Abstract
Description
[Technical field]
[0001] The present invention relates to an experiment data processing system, a data processing device, and a program related to the processing. [Background technology]
[0002] A graphing function calculator, which is a type of desktop calculator, can calculate simultaneous equations and perform operations using variables, and can draw graphs of the calculation results and display them on a display.Graphing function calculators equipped with a function for connecting to sensors are also in widespread use, and can draw graphs of measurement results based on data obtained from the sensors and display them on a display (for example, Patent Document 1).
[0003] Such graphing scientific calculators are often used in situations such as science experiment classes at schools. For example, data measured during an experiment by a learner (student) is sent to the graphing scientific calculator via a data logger for data collection, and the data transferred to the graphing scientific calculator is plotted in a coordinate system with separately set coordinate axes to create a graph.
[0004] In recent years, learning support devices that use computers to support learners in school classes, exams, individual learning, etc., as well as learning support systems that connect learning support devices over a network to form a system, have become widely used (for example, Patent Document 2).

[0005] [Patent Document 1] JP 2005-10850 A [Patent Document 2] JP 2004-53766 A Summary of the Invention [Problem to be solved by the invention]
[0006] The purpose of laboratory classes is to understand the laws of physics and chemistry through experiments, and in order to achieve this, it is necessary to obtain correct experimental results. However, there have been cases where the basis for judging whether an experiment is being conducted correctly was not clear, and the accuracy of the judgment was inconsistent. For example, the judgment of the results of a conventional experiment largely included a qualitative element, in which the teacher visually compared the actual experimental results with the correct (ideal) experimental results described in a textbook or laboratory text. Furthermore, when there are a large number of students, it takes a lot of time and effort for the teacher to check all the experimental results. In addition, experience and skill are required to properly judge experimental results, and it takes a lot of time and money to train and secure teachers with such capabilities.
[0007] In addition, in the case of distance experimental classes in which the students and teachers are separated, the process of the students presenting their experimental results to the teacher and the teacher presenting the students with an evaluation of the experimental results takes a certain amount of time, even when online communication methods are used.
[0008] For simple test questions in which students select answers from pre-prepared options, conventional learning support systems can automate the process from answering questions to notifying students whether their answers are correct or not, using computers and networks, making learning more efficient. However, for learning tasks such as science experiments, where various factors are involved and have complex effects on the results, existing learning support systems were not able to adequately handle such tasks.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0018] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. Fig. 1 is a block diagram showing a configuration example of an experiment data processing system 1 including a graph function calculator 10 and a tablet terminal 30, which are embodiments of a data processing device and an evaluation device of the present invention. Figs. 2 to 5 are diagrams showing examples of use of the experiment data processing system 1.
[0019] The graph function calculator 10 and the tablet terminal 30 can communicate with each other via the communication unit 17 and the communication unit 35, and the communication unit 17 and the communication unit 35 are equipped with communication units compatible with each other's communication standards. The communication between the communication unit 17 and the communication unit 35 may be wireless or wired. In addition, the graph function calculator 10 and the tablet terminal 30 may communicate directly, or may communicate via a network 40. As an example of a direct communication means between the graph function calculator 10 and the tablet terminal 30, a type of short-range wireless communication that is often installed in smartphones and the like can be used. In addition, the network 40 may be further connected to an external Web server 41, and the graph function calculator 10 and the tablet terminal 30 may communicate with the Web server 41.
[0020] The experimental data processing system 1 is used, for example, in science experiment classes at school. Each learner (student) participating in the experiment uses an individual graphing scientific calculator 10 and tablet terminal 30. Alternatively, a single graphing scientific calculator 10 may be shared by a learning group consisting of multiple learners. When multiple people share the graphing scientific calculator 10, the tablet terminal 30 that transmits and receives data to and from the graphing scientific calculator 10 may be automatically selected using user information added to the experiment result data described below.
[0021] The graphing function calculator 10 is a type of desktop calculator, and in addition to the calculation functions of a general function calculator, it has the function of acquiring data (measurement contents) measured by various sensors 21, which are measuring means, via a data logger 20 (data acquisition function), the function of generating experimental result data based on the acquired data (experimental result data generation function), and the function of outputting the experimental result data to a tablet terminal 30 (experimental result data output function).
[0022] The tablet terminal 30 is a type of portable information terminal, and in addition to the functions of a general tablet terminal, it has the function of receiving and acquiring experimental result data output from the graphing function calculator 10 (experimental result data acquisition function), the function of evaluating the experimental results based on the experimental result data received from the graphing function calculator 10 (experiment evaluation function), and the function of notifying the results of the evaluation (notification function).
[0023] The schematic configuration of the electronic circuit of graphing scientific calculator 10 is shown in Figure 1. In graphing scientific calculator 10, the components included in the block diagram of Figure 1 work together to function as a control unit. The electronic circuit of graphing scientific calculator 10 has a CPU (Central Processing Unit) 11, which is a computer, and an input unit 12, a display unit 13, a memory 14, a recording medium reading unit 15, a data acquisition unit 16, and a communication unit 17 are connected to CPU 11.
[0024] The input unit 12 is a part that accepts user operations. As shown in Figures 2 to 5, the input unit 12 is provided with a plurality of keys (hardware keys) that can be pressed into the front side of the housing of the graphing scientific calculator 10 as elements that make up the input unit 12. When the user operates these keys, instructions related to calculations such as numerical values, operation symbols, and functions, instructions to execute applications, instructions related to settings of the graphing scientific calculator 10, etc. are input to the CPU 11 as predetermined operation signals.
[0025] As shown in Figures 2 to 5, the display surface of the display unit 13 is disposed on the front side of the housing of the graphing scientific calculator 10. The display unit 13 includes a display device that displays characters, symbols, images, etc. on the display surface in a dot matrix format, and a display driver that causes the display device to display (draw) images under the control of the CPU 11. As the display device, an LCD (Liquid Crystal Display) or an LED (Light Emitting Diode) is used. The type of display device used for the display unit 13 is not limited to this, and any device capable of displaying information such as graphs, which will be described later, may be used.
[0026] It is also possible to use another type of input unit instead of (or in combination with) an input unit using hardware keys such as the input unit 12 of this embodiment. As an example, the display surface of the display unit 13 may be configured to double as a touch panel type input unit, or a voice input microphone for voice operation may be provided.
[0027] The memory 14 is composed of a ROM (Read Only Memory), which is a semiconductor memory that is read-only, and a RAM (Random Access Memory), which is a semiconductor memory that is randomly accessible. Various processing programs are stored in the ROM. The CPU 11 performs overall control of the graphing scientific calculator 10 by reading and executing the programs from the ROM in response to operation signals from the input unit 12. The RAM is used as a working area for the programs and data (e.g., temporary data such as numerical values during calculation) when the CPU 11 executes the programs.
[0028] A user information storage area is provided in the memory 14, and user information for identifying a user who uses the graphing scientific calculator 10 can be stored therein.
[0029] The processing programs stored in memory 14 include an experiment support program 14a (an application for experimental teaching) for causing graphing scientific calculator 10 to function as a component of experimental data processing system 1. Experiment support program 14a may be a pre-installed type stored in graphing scientific calculator 10 in advance, or may be distributed in a form that allows a user to install it later on graphing scientific calculator 10. Graphing scientific calculator 10 realizes a data acquisition function, an experiment result data generation function, and an experiment result data output function by CPU 11 controlling the operation of each part according to the commands written in experiment support program 14a.
[0030] The recording medium reading unit 15 reads and writes data from and to an external recording medium such as a memory card attached to the graphing scientific calculator 10. Programs such as the experiment support program 14a may be stored in an external recording medium and input to the graphing scientific calculator 10. Experiment result data generated by the graphing scientific calculator 10 may also be output to an external recording medium.
[0031] The data acquisition unit 16 is an interface for connection to a data logger 20. The data logger 20 collects data by measuring a particular scientific property such as voltage, current, pressure, temperature, pH, sound pressure, light, etc.
[0032] A sensor 21, which is a measuring means, is connected to the data logger 20. The data logger 20 is equipped with a plurality of channels CH1, CH2, ... for connecting the sensors 21, a data memory 22 for storing the measurement data input from the sensor 21, and a connection interface 23 for connecting to the graphing scientific calculator 10.
[0033] In this embodiment, a current sensor 21a is connected to channel CH1, and a voltage sensor 21b is connected to channel CH2, and an experiment is performed to measure the current and voltage in an electric circuit. The current value measured by the current sensor 21a and the voltage value measured by the voltage sensor 21b are input to the data logger 20 via channels CH1 and CH2. The input measurement data of the current and voltage are temporarily stored in the data memory 22. Note that the measurement target in the experiment is not limited to the current and voltage, and the present invention can be applied to various experiments as long as some measurement that can be converted into data is performed by a measurement means.
[0034] The data acquisition unit 16 of the graphing scientific calculator 10 and the connection interface 23 of the data logger 20 are connected to each other so that they can communicate data with each other via a communication cable 24. Note that the form of communication between the graphing scientific calculator 10 and the data logger 20 is not limited to this, and data communication may be performed via a wireless connection instead of a wired connection via the communication cable 24.
[0035] The data acquisition function in the experiment support program 14a of the graphing scientific calculator 10 controls communication so that, with the graphing scientific calculator 10 and the data logger 20 connected so as to enable data communication, the measurement data stored in the data memory 22 is imported into the graphing scientific calculator 10. The measurement data input from the data logger 20 to the graphing scientific calculator 10 is stored in the data storage area of the memory 14.
[0036] In this embodiment, the graphing scientific calculator 10 and the data logger 20 are separate entities, but the configuration and functions corresponding to the data logger 20 may be built into (integrated with) the graphing scientific calculator 10. In this case, the sensor 21 may be directly connected to the data acquisition unit 16, and the measurement data obtained by the sensor 21 may be directly stored in the memory 14 of the graphing scientific calculator 10.
[0037] The experiment result data generation function in the experiment support program 14a of the graphing scientific calculator 10 draws a graph showing the experiment results based on the measurement data acquired via the data logger 20 and displays it on the display unit 13. The process of drawing this graph is the generation of the experiment result data. In other words, the generation of the experiment result data is a process of processing the measurement contents of the sensor 21, which is a measuring means, in a predetermined format to make the experiment results evaluable. For example, a graph can be generated by plotting the current value and voltage value acquired from the current sensor 21a and the voltage sensor 21b in a coordinate system with the vertical axis representing current and the horizontal axis representing voltage. Then, this experiment result graph G1 (see FIG. 2) is drawn (displayed) on the display surface of the display unit 13.
[0038] As described above, the graphing scientific calculator 10 can acquire measurement data from the sensor 21 and perform data processing such as drawing graphs of experimental results, and has a standalone experiment support function. Furthermore, as described below, by linking the graphing scientific calculator 10 with the tablet terminal 30, a more advanced and convenient experiment support function can be obtained.
[0039] The experiment result data output function in the experiment support program 14a of the graphing scientific calculator 10 outputs the experiment result data (experimental result graph G1) generated by the graphing scientific calculator 10 to the communication unit 17, and transmits the experiment result data to the tablet terminal 30. The experiment result data transmitted from the graphing scientific calculator 10 to the tablet terminal 30 may be data that allows the tablet terminal 30 to perform a comparative evaluation of the experiment results described below. For example, the original measurement data acquired from the data logger 20 may be supplemented with information on the type of sensor 21 and graph drawing format data used to draw the experiment result graph G1, and this may be output as the experiment result data.
[0040] Furthermore, a timestamp and user information may be added to the experiment result data output by the graphing scientific calculator 10. When one graphing scientific calculator 10 is shared by multiple people, communication can be managed so that the experiment result data is sent only to the tablet terminal 30 that matches the user information output by the graphing scientific calculator 10 among the multiple tablet terminals 30.
[0041] The schematic configuration of the electronic circuit of the tablet terminal 30 is shown in Fig. 1. In the tablet terminal 30, the components included in the block diagram of Fig. 1 work together to function as a control unit. The electronic circuit of the tablet terminal 30 includes a CPU 31, which is a computer, a display unit 32 with a touch panel, a memory 33, a recording medium reading unit 34, and a communication unit 35.
[0042] Display unit 32 is equipped with a dot-matrix display device similar to display unit 13 in graphing scientific calculator 10, and displays various types of information such as characters, symbols, images, etc. Display unit 32 also serves as an input unit that accepts user operations, and user operations performed through display unit 32 are input to CPU 31 as predetermined operation signals.
[0043] Various processing programs are stored in the memory 33. The CPU 31 performs overall control of the tablet terminal 30 by reading and executing the programs from the memory 33 in response to operation signals from the display unit 32.
[0044] The processing programs stored in the memory 33 include an experiment support program 33a (an application for experimental teaching, an electronic textbook application) for causing the tablet terminal 30 to function as a component of the experiment data processing system 1. This experiment support program 33a may be a pre-installed type stored in advance in the tablet terminal 30, or may be distributed in a form that allows the user to install it later on the tablet terminal 30. The tablet terminal 30 realizes an experiment result data acquisition function, an experiment evaluation function, and a notification function by the CPU 31 controlling the operation of each part according to the commands written in the experiment support program 33a.
[0045] Electronic textbook data 33b is stored in memory 33. Electronic textbook data 33b may be stored in advance in tablet terminal 30, or may be provided by downloading from network 40 or Web server 41. Electronic textbook data 33b is created in an electronic document format such as PDF (Portable Document Format) and includes an experimental lesson page. The experimental lesson page describes the purpose and procedure of the experiment, and the learner refers to the page when preparing and working on the experiment.
[0046] 2 to 5 show a state in which a page of an experimental lesson in electronic textbook data 33b is displayed on display unit 32 of tablet terminal 30. A notification area 33c is set in a part of the page of the experimental lesson. Notification area 33c is an area in which the display contents can be dynamically changed according to the progress of the experiment and the evaluation of the experimental results. The display contents of notification area 33c are changed under the control of experiment support program 33a.
[0047] The electronic textbook data 33b further stores model experiment result data. The model experiment result data is data related to a preset (predicted or assumed) experimental result, and is a typology of the relationship between the preconditions and results of an experiment, such as "if an experiment is performed under these conditions, this experimental result will be obtained." The model experiment result data is stored as a graph with a common data format to the graph of the experimental result data output by the graphing scientific calculator 10. Specifically, the graph of the experimental result data and the graph of the model experiment result data use graphs with the same representation among various graphs such as line graphs and bar graphs, and further have the same scale widths and units of the vertical and horizontal axes, and are generated in a state where a comparison and evaluation of the degree of agreement can be made. A graph with such a relationship is called a graph with a common format. Then, when the graphing scientific calculator 10 outputs graph data (experiment result graph G1) as the experimental result data, the graph of the experimental result data and the graph data with the common format are stored as the model experiment result data in the electronic textbook data 33b. The model experiment result data may be set so that it cannot be viewed by students before or during the experiment.
[0048] The model experiment result data stored in the electronic textbook data 33b includes at least model experiment result data (hereinafter referred to as theoretical value experiment data) showing the experiment results when the measurements in the experiment are performed correctly (ideal values).
[0049] The recording medium reading unit 34 reads and writes data from an external recording medium, such as a memory card, attached to the tablet terminal 30. Programs, such as the experiment support program 33a, and electronic textbook data 33b may be stored in the external recording medium and input to the tablet terminal 30.
[0050] The communication unit 35 has a communication standard and a communication interface compatible with the communication unit 17 of the graphing scientific calculator 10 , and is capable of mutual data communication with the graphing scientific calculator 10 .
[0051] The experiment result data acquisition function in the experiment support program 33a of the tablet terminal 30 controls communication so that, when the graphing scientific calculator 10 and the tablet terminal 30 are capable of data communication, the experiment result data transmitted from the graphing scientific calculator 10 is imported into the tablet terminal 30. The experiment result data input from the graphing scientific calculator 10 to the tablet terminal 30 is stored in a data storage area of the memory 33.
[0052] The experiment evaluation function in the experiment support program 33a of the tablet terminal 30 evaluates the experiment results based on the experiment result data input to the tablet terminal 30 by referring to the contents of the electronic textbook data 33b.
[0053] Specifically, the experiment support program 33a has a graph drawing function similar to that of the graphing scientific calculator 10, and draws an experiment result graph from the experiment result data input from the graphing scientific calculator 10. In the example of Fig. 2, the experiment result graph G1 is displayed in the notification area 33c of the experiment lesson page of the display unit 32.
[0054] The experiment evaluation function in the experiment support program 33a compares a graph of theoretical experimental data showing an ideal experimental result stored as model experimental result data in the electronic textbook data 33b with an experimental result graph G1, which is experimental result data obtained based on actual measurement data, and calculates the degree of agreement. The least two-row method or the like can be used to calculate the degree of agreement. A reference value (threshold value) is set for the degree of agreement, and if the degree of agreement is higher than the reference value, it is determined that the experimental result is correct. On the other hand, if the degree of agreement does not meet the reference value, it is determined that the experimental result is incorrect. In this way, the correctness of the experimental result data is judged. Elements such as the level of the reference value and the selection of the range of the graph used for the judgment can be appropriately set according to the type of experiment, the purpose of the experiment, the accuracy required for the experiment, etc.
[0055] The notification function in the experiment support program 33a of the tablet terminal 30 notifies the user (learner) of the above-mentioned judgment result by the experiment evaluation function. For example, FIG. 3 shows a notification form in which the display unit 32 is used as a notification means, and the word "OK" indicating the judgment content that the experiment result is correct is displayed in the notification area 33c of the display unit 32. If it is judged that the experiment result is incorrect, "NG" is displayed in the notification area 33c of the display unit 32 (see FIG. 5). The display indicating the judgment content is not limited to such text information, and it is also possible to notify by symbols, icons, blinking or lighting, changing the display color of the experiment result graph, etc. By notifying the display unit 32, the learner who performed the experiment can quickly obtain the judgment result of whether the experiment was performed appropriately or not.
[0056] In addition, as a notification means other than display on the display unit 32, it is also possible to use a voice notification using a speaker provided in the tablet terminal 30, or a vibration notification using a vibrator provided in the tablet terminal 30, etc.
[0057] The model experiment result data stored in the electronic textbook data 33b may not only be theoretical experimental data showing correct experimental results, but also model experiment result data in cases where the experimental method is incorrect and measurements are not performed correctly (error state) (hereinafter referred to as error experiment data). In particular, it is desirable to associate the causes of the error state with the error experiment data, and to store a database of error causes and their results in a typological form.
[0058] The experiment evaluation function in the experiment support program 33a compares the error experiment data with the experimental result data, in addition to comparing the theoretical value experiment data with the experimental result data (theoretical values and experimental values) described above. For example, the error experiment data is created as graph data in a common format with the experimental result data, and is evaluated based on the degree of agreement between the graphs. If the degree of agreement is equal to or exceeds a reference value and it is determined that the experimental result data corresponds to the error experiment data, the cause of the error state (error in the experimental method) can be inferred from the error experiment data. In response to this, the notification function in the experiment support program 33a notifies the user (learner) of the error state in addition to determining whether the experimental result is correct.
[0059] 4 shows the experimental results when the current sensor 21a and the voltage sensor 21b are connected in the opposite direction to the correct connection destination of the circuit to be measured. On the graphing scientific calculator 10 and the tablet terminal 30, an experimental result graph G2 is drawn, which is different from the experimental result graph G1 which is the correct experimental result.
[0060] The electronic textbook data 33b stores, as one type of erroneous experimental data, graph data in which the current sensor 21a and the voltage sensor 21b are connected in reverse, together with information indicating the cause. The experiment evaluation function in the experiment support program 33a first determines that the experimental result graph G2 is not a correct experimental result by comparing it with a graph of theoretical experimental data. It then compares the graph data of the erroneous experimental data with the experimental result graph G2 to calculate the degree of agreement, and if the degree of agreement is equal to or greater than a reference value, determines that the erroneous experimental result is caused by the current sensor 21a and the voltage sensor 21b being connected in reverse.
[0061] In response to this determination, the notification function in the experiment support program 33a of the tablet terminal 30 causes the notification area 33c of the experiment lesson page in the display unit 32 to notify the user of the error state, as shown in Fig. 5. Specifically, in addition to displaying the word "NG" to indicate that the experiment result is incorrect, the cause of the error and advice for remedying the error are displayed as text information. This allows the learner to quickly and in detail know the error in the experiment method.
[0062] The error state can be notified not only by display on the display unit 32, but also by voice using a speaker provided in the tablet terminal 30. If it is difficult to convey complex information by the notification means, error codes (such as combinations of several digits and letters) corresponding to various error states may be prepared, and the notification means may only notify the error codes. The error codes and their meanings may be written in the electronic textbook data 33b.
[0063] In this embodiment, the case where the current sensor 21a and the voltage sensor 21b are connected to the wrong destination is illustrated, but the expected error state varies depending on the type and procedure of the experiment, and is not limited to the above example. There are various error states, such as a wrong resistor value attached to the circuit, a wrong setting of Celsius and Fahrenheit in a measurement using a temperature sensor, and an air leak in a measurement using a pressure sensor, which are just a few examples. Since it is difficult to cover all error states in an experiment, it is practical to pick up representative situations in which many learners are likely to make errors and in which error states are likely to appear in error experiment data (easy to determine errors in the experiment) and store them in the electronic textbook data 33b.
[0064] In this invention, the comparative evaluation of experimental results and notification of the evaluation include not only the determination and notification of correctness by comparing theoretical experimental data with experimental result data, but also the determination of the type of error state by comparing error experimental data with experimental result data, and notification regarding the cause of the error state and improvements.
[0065] As described above, in the experimental data processing system 1 of this embodiment, the experimental support programs 14a and 33a cooperate with each other to operate the respective control units of the graphing scientific calculator 10 and the tablet terminal 30, and the experimental results are evaluated and the contents of the evaluation are notified by comparing the degree of agreement between the graph of the experimental result data generated by the graphing scientific calculator 10 based on the measurement contents acquired from the sensor 21 and the graph of the model experimental result data (theoretical value experimental data, error experimental data) incorporated in the electronic textbook data 33b. This makes it possible to quantitatively determine the correctness of the experimental results without relying on qualitative judgments such as visual confirmation by the teacher. For example, even if a teacher who is skilled in evaluating experimental results is absent, it is possible to reliably know whether the experimental results are correct or not. In addition, even if there are a large number of learners compared to the number of teachers, an evaluation of the experimental results based on equal evaluation criteria is quickly provided to each learner, improving the efficiency of learning the experiment.
[0066] An example of processing by the experimental data processing system 1 will be described with reference to the flowcharts of Figures 6 and 7. In the following description, unless the subject of control or processing is specified, it is assumed that the CPU 11 in the graphing scientific calculator 10 and the CPU 31 in the tablet terminal 30 control the control unit and perform processing.
[0067] Fig. 6 shows the processing in the graphing scientific calculator 10. At the start of this processing, the experiment is completed, and measurement data obtained via the sensor 21 is stored in the data memory 22 of the data logger 20. The processing shown in Fig. 6 is started when the user operates the input unit 12 to instruct the graphing scientific calculator 10 to execute the experiment support program 14a. Subsequent processing is performed by the CPU 11 controlling the operation of each unit according to the commands written in the experiment support program 14a.
[0068] In step S100, it is checked whether data communication is possible between the graphing scientific calculator 10 and the data logger 20. If data communication is not possible (step S100: NO), the process waits until communication with the data logger 20 is established. At this time, a message prompting the user to confirm the connection with the data logger 20 may be displayed on the display unit 13. If data communication is possible (step S100: YES), the process proceeds to step S101, where measurement data is imported from the data logger 20 and the measurement data is stored in the memory 14.
[0069] Next, the process proceeds to step S102, where an experimental result graph is drawn based on the measurement data stored in memory 14, and the experimental result graph is displayed on display unit 13. If the experiment is performed correctly, the experimental result graph will be G1 as shown in Figures 2 and 3, and if the experiment is performed incorrectly, the experimental result graph will be G2 as shown in Figures 4 and 5.
[0070] After drawing the experimental result graph, in step S103, it is checked whether data communication is possible between the graphing scientific calculator 10 and the tablet terminal 30. If data communication is not possible (step S103: NO), the calculator waits until communication with the tablet terminal 30 is established. At this time, a message prompting the user to confirm connection with the tablet terminal 30 may be displayed on the display unit 13. If data communication is possible (step S103: YES), the calculator proceeds to step S104, and the experimental result data including the experimental result graph is transmitted to the tablet terminal 30.
[0071] Fig. 7 shows the processing in tablet terminal 30. The processing shown in Fig. 7 is started when the user operates the touch panel of display unit 32 to instruct execution of experiment support program 33a in tablet terminal 30. Note that electronic textbook data 33b may be associated with experiment support program 33a, and experiment support program 33a may be executed when a file of electronic textbook data 33b is opened or a predetermined location of the electronic textbook displayed on display unit 32 is touched. Subsequent processing is performed by CPU 31 controlling the operation of each unit according to the instructions written in experiment support program 33a.
[0072] In step S200, it is checked whether data communication is possible between the graphing scientific calculator 10 and the tablet terminal 30. If data communication is not possible (step S200: NO), the system waits for communication to be established with the graphing scientific calculator 10. At this time, a message prompting the user to confirm the connection with the graphing scientific calculator 10 may be displayed on the display unit 32. If data communication is possible (step S200: YES), the system proceeds to step S201, where the experiment result data (experimental result graph) is imported from the graphing scientific calculator 10 and the experiment result data (experimental result graph) is stored in the memory 33.
[0073] Next, the process proceeds to step S202, where the degree of agreement between the graph of the experimental result data acquired from the graphing scientific calculator 10 and the graph of the theoretical experimental data among the model experimental result data stored in the electronic textbook data 33b is determined. If the degree of agreement is equal to or greater than the reference value (step S202: YES), the experimental result is determined to be correct, and the process proceeds to step S203. In step S203, a display indicating that the experimental result is correct is displayed on the display unit 32 (see FIG. 3).
[0074] If the degree of agreement between the graph of the experimental result data and the graph of the theoretical experimental data does not meet the reference value (step S202: NO), it is determined that the experimental result is incorrect, and the process proceeds to step S204. In step S204, it determines the degree of agreement between the graph of the experimental result data acquired from the graphing scientific calculator 10 and the graph of the error experimental data among the model experimental result data stored in the electronic textbook data 33b. If there are multiple graphs of error experimental data, it sequentially determines the degree of agreement with the graph of each error experimental data.
[0075] If the degree of agreement between the graph of the experimental result data and the graph of the error experimental data (if there are multiple graphs of error experimental data, any of them) is equal to or greater than the reference value (step S204: YES), the process proceeds to step S205. Here, since there is error experimental data that has been found to match the experimental result data, the user can be informed of the content of the error in the experimental method and advice for improvement by referring to the information on the error state associated with the error experimental data. Therefore, in step S205, in addition to the erroneous experimental result, a display including information on the error state is displayed on the display unit 32 (see FIG. 5).
[0076] If the degree of agreement between the graph of the experimental result data and the graph of the error experimental data (if there are multiple graphs of error experimental data, all of them) does not meet the reference value (step S204: NO), proceed to step S206. Here, since there is no error experimental data that has been found to match the experimental result data and the details of the experimental error cannot be identified, in step S206, only a display indicating that the experimental result is incorrect is displayed on the display unit 32.
[0077] Once the evaluation content regarding the experiment results has been notified (displayed on the display unit 32) in any of step S203, step S205, or step S206, the processing of the experiment support program 33a on the tablet terminal 30 ends and the flow chart of FIG. 7 is exited.
[0078] In the experimental data processing system 1 of this embodiment, the graphing scientific calculator 10, which is a data processing device, has a data acquisition function for acquiring measurement contents by the sensor 21, and an experimental result data generation function for generating experimental result data in a predetermined format, such as a graph, from the acquired measurement contents. The tablet terminal 30, which is an evaluation device, has an experiment evaluation function for evaluating the experimental results based on the experimental result data received from the graphing scientific calculator 10. There are advantages to sharing functions between the graphing scientific calculator 10 and the tablet terminal 30 in this manner.
[0079] Graphing function calculators that process input data and draw graphs are already in practical use and are on the market. Therefore, in the graphing function calculator 10, the technology of existing graphing function calculators can be used for data processing of the measurement content that is the basis, making it highly versatile. Furthermore, the role of the graphing function calculator 10 in the experiment data processing system 1 is limited to outputting the experiment result data to the tablet terminal 30, so the processing and control burden on the graphing function calculator 10 can be reduced.
[0080] The tablet terminal 30 stores electronic textbook data 33b including model experiment result data to be compared with the experiment result data. From the viewpoints of ease of viewing and hardware performance, it is suitable to view the experiment lesson page of the electronic textbook data 33b on a tablet terminal 30 having a display unit 32 with a large display surface. In addition, the more examples of expected experiment failures there are, the larger the amount of error experiment data included in the model experiment result data becomes, and accordingly the amount of data in the electronic textbook data 33b and the processing load when performing comparative evaluation of the experiment result data increase. Therefore, in the experiment data processing system 1, it is suitable to use the tablet terminal 30, which is more likely to have higher processing performance than the graphing scientific calculator 10, as an evaluation device.
[0081] The above embodiment is a specific example shown to facilitate understanding of the invention, and the present invention is not limited to this embodiment, and various modifications and changes are possible without departing from the gist of the invention. Below, modifications different from the above embodiment will be described.
[0082] In the above embodiment, the graphing scientific calculator 10 generates the experimental result data in a graph format. The graphing improves the visibility of the experimental results and makes it easier to make judgments. However, the experimental result data may be generated in a format other than a graph. For example, the graphing scientific calculator 10 may generate experimental result data in a table format. In this case, the model experimental result data that is referred to when evaluating the experimental result data on the tablet terminal 30 is also in a table format.
[0083] In the above embodiment, the evaluation content of the experiment result data is notified by the tablet terminal 30, but the evaluation content may be notified by the graphing scientific calculator 10. For example, by adding a step of transmitting the evaluation content (determination result) from the tablet terminal 30 to the graphing scientific calculator 10 before steps S203, S205, and S206 in the flowchart of Fig. 7, the notification in steps S203, S205, and S206 can be made by the display unit 13 of the graphing scientific calculator 10 or the like (the display unit 13 can be used as the notification means). Also, the evaluation content can be notified by both the graphing scientific calculator 10 and the tablet terminal 30.
[0084] In the above embodiment, data transfer between the graphing scientific calculator 10 and the tablet terminal 30 is performed by a wireless or wired connection via the communication units 17 and 35. Alternatively, it is also possible to transfer experimental result data and the like using an external recording medium that is detachably attached to the recording medium reading unit 15 and the recording medium reading unit 34.
[0085] Furthermore, data transfer between the graphing scientific calculator 10 and the tablet terminal 30 may be performed by a method other than sending and receiving electronic data. For example, content corresponding to the experimental result data may be displayed on the display unit 13 of the graphing scientific calculator 10 in the form of a graph or two-dimensional code, the displayed content may be photographed using the camera function of the tablet terminal 30, and the photographed image may be processed and digitized so that the tablet terminal 30 can obtain the experimental result data.
[0086] The data processing device in the experimental data processing system can be configured as a dedicated graphing function calculator 10, or as a smartphone, personal digital assistant, personal computer, etc. (implemented with a program equivalent to the experimental support program 14a) that has the function of generating and outputting experimental result data.
[0087] The evaluation device in the experimental data processing system may be configured as a tablet terminal 30 capable of communicating directly with the data processing device (graphing scientific calculator 10), or may be configured as a Web server 41 (see FIG. 1) that communicates with the graphing scientific calculator 10 and the tablet terminal 30 via a network 40. For example, experimental result data is transmitted from the graphing scientific calculator 10 or the tablet terminal 30 to the Web server 41, and a comparative evaluation is performed on the Web server 41 between the experimental result data and model experimental result data, and the evaluation result is transmitted from the Web server 41 to the graphing scientific calculator 10 or the tablet terminal 30 for display. In this case, the electronic textbook data 33b may be stored in the Web server 41 instead of the tablet terminal 30.
[0088] As a further modified example, model experiment result data (theoretical value experiment data, error experiment data) can be sent from the tablet terminal 30 or Web server 41 storing electronic textbook data to a data processing device corresponding to the graphing scientific calculator 10, and the experiment result data and the model experiment result data can be compared and evaluated on the data processing device side. In this case, since the data processing device has the experiment evaluation function that the tablet terminal 30 (evaluation device) in the above embodiment has, the evaluation device having an independent configuration can be omitted. For example, the tablet terminal 30 is used to view electronic textbook data, but the generation of the experiment result data and the process up to its evaluation can be completed not by the tablet terminal 30 but by the graphing scientific calculator 10 (or a smartphone instead of the graphing scientific calculator 10). The evaluation content of the experiment result data performed by the graphing scientific calculator 10 may be displayed on the display unit 13 of the graphing scientific calculator 10 itself, or may be transmitted to the tablet terminal 30 and displayed on the display unit 32.
