Background Technology

[0002] Internet-based educational services, such as online lectures or cyber lectures, are becoming increasingly popular. Furthermore, to overcome the limitations of offline lectures that are restricted by time and space, online lectures, which offer freedom of choice in time and location, are becoming even more prevalent.

[0003] However, in online lectures, it is very difficult to maintain a high level of concentration because it is impossible to communicate face-to-face in real time and receiving immediate feedback is difficult.

[0004] In particular, when using non-face-to-face learning methods during the process of understanding and memorizing English grammar, which has a different linguistic structure from Korean, it is easy for problems to arise where interest in learning English and concentration decrease.

[0005] Therefore, there is a growing need for learning methods that maintain learners' high concentration even when conducting online lectures remotely, and in particular, maximize the effects of understanding and memorization. Prior art literature

[0030] FIG. 1 is a simplified block diagram illustrating an electronic device (100) that performs an educational material provision operation using concept cards according to an exemplary embodiment of the present disclosure.

[0031] Referring to FIG. 1, an electronic device (100) that performs the operation of providing educational materials using concept cards may include an input / output module (110), a communication module (120), a memory (130), and a processor (140). Hereinafter, the electronic device (100) is an electronic device that provides educational materials for performing English education using concept cards, and the method of providing educational materials using concept cards is assumed to be implemented through the electronic device (100) that performs the operation of providing educational materials using concept cards.

[0032] The input / output module (110) may be various interfaces or connection ports that receive user input or output information to the user. The input / output module (110) may be divided into an input module and an output module.

[0033] The input module receives user input from the user. The input module is for inputting video information (or signals), audio information (or signals), data, or information input by the user, and may include at least one of at least one camera, at least one microphone, and a user input unit. Voice data or image data collected by the input unit may be analyzed and processed into a user control command.

[0034] User input can take various forms, including key input, touch input, and voice input. Examples of input modules capable of receiving such user input include traditional keypads, keyboards, and mice; as well as touch sensors that detect user touch; microphones that receive voice signals; cameras that recognize gestures through image recognition; proximity sensors consisting of light or infrared sensors that detect user approach; motion sensors that recognize user movements using accelerometers or gyroscopes; and all other diverse forms of input means that detect or receive various types of user input. This is a comprehensive concept.

[0035] Here, the touch sensor can be implemented as a piezoelectric or capacitive touch sensor that detects touch through a touch panel or touch film attached to the display panel, or as an optical touch sensor that detects touch by an optical method. In addition, the input module may be implemented in the form of an input interface (USB port, PS / 2 port, etc.) that connects an external input device to receive user input, instead of a device that detects user input itself.

[0036] The output module can output various types of information and provide it to the user. The output module is a comprehensive concept that includes a display for outputting video, a speaker for outputting sound (and / or an amplifier connected thereto), a haptic device for generating vibration, and various other forms of output means. In addition, the output module may be implemented in the form of a port-type output interface that connects the individual output means described above.

[0037] For example, an output module in the form of a display can display text, still images, and videos. The term "display" refers to a broad concept of an image display device that includes all types of devices capable of performing image output functions, such as Liquid Crystal Displays (LCDs), Light Emitting Diode (LED) displays, Organic Light Emitting Diode (OLED) displays, Flat Panel Displays (FPDs), transparent displays, Curved Displays, flexible displays, 1D displays, holographic displays, projectors, and others. Such a display may also take the form of a touch display integrated with the touch sensor of an input module.

[0038] In other words, the input / output module (110) can receive user input or provide output to the user based on a user interface.

[0039] The communication module (120) can communicate with an external device. Accordingly, the device can transmit and receive information with an external device through the communication module. For example, the device can communicate with an external device using the communication module so that information stored and generated within the electric vehicle charging management system is shared. The communication module (120) may include, for example, at least one of a wired communication module, a wireless communication module, a short-range communication module, and a location information module.

[0040] Here, communication, that is, the transmission and reception of data, can be performed via wired or wireless means. To this end, the communication module may be composed of a wired communication module that connects to the Internet, etc., via a Local Area Network (LAN); a mobile communication module that connects to a mobile communication network via a mobile communication base station to transmit and receive data; a short-range communication module that uses a Wireless Local Area Network (WLAN) family communication method such as Wi-Fi or a Wireless Personal Area Network (WPAN) family communication method such as Bluetooth or Zigbee; a satellite communication module that uses a Global Navigation Satellite System (GNSS) such as GPS; or a combination thereof. The wireless communication technology used for communication may include Narrowband Internet of Things (NB-IoT) for low-power communication. In this case, for example, NB-IoT technology may be an example of LPWAN (Low Power Wide Area Network) technology and may be implemented according to standards such as LTE Cat (category) NB1 and / or LTE Cat NB2, but is not limited to the names mentioned above. Additionally, or generally, wireless communication technology implemented in wireless devices according to various embodiments may perform communication based on LTE-M technology. In this case, for example, LTE-M technology may be an example of LPWAN technology and may be referred to by various names such as eMTC (enhanced Machine Type Communication).For example, LTE-M technology may be implemented in at least one of various standards such as 1) LTE CAT 0, 2) LTE Cat M1, 3) LTE Cat M2, 4) LTE non-BL (non-Bandwidth Limited), 5) LTE-MTC, 6) LTE Machine Type Communication, and / or 7) LTE M, and is not limited to the names mentioned above. Additionally or generally, wireless communication technology implemented in wireless devices according to various embodiments may include at least one of ZigBee, Bluetooth, and Low Power Wide Area Network (LPWAN) for low-power communication, and is not limited to the names mentioned above. As an example, ZigBee technology can create personal area networks (PANs) related to small / low-power digital communication based on various standards such as IEEE 802.15.4 and may be referred to by various names.

[0041] The wired communication module may include various wired communication modules such as a Local Area Network (LAN) module, a Wide Area Network (WAN) module, or a Value Added Network (VAN) module, as well as various cable communication modules such as USB (Universal Serial Bus), HDMI (High Definition Multimedia Interface), DVI (Digital Visual Interface), RS-232 (recommended standard 232), power line communication, or POTS (plain old telephone service).

[0042] In addition to Wi-Fi modules and WiBro (Wireless broadband) modules, the wireless communication module may include wireless communication modules that support various wireless communication methods such as GSM (global System for Mobile Communication), CDMA (Code Division Multiple Access), WCDMA (Wideband Code Division Multiple Access), UMTS (universal mobile telecommunications system), TDMA (Time Division Multiple Access), LTE (Long Term Evolution), 4G, 5G, and 6G.

[0043] The wireless communication module may include a wireless communication interface comprising an antenna and a transmitter that transmit a signal. Additionally, the wireless communication module may further include a signal conversion module that modulates a digital control signal output from the control unit through the wireless communication interface into an analog wireless signal under the control of the control unit.

[0044] The wireless communication module may include a wireless communication interface comprising an antenna for receiving signals and a receiver. Additionally, the wireless communication module may further include a signal conversion module for demodulating an analog wireless signal received through the wireless communication interface into a digital control signal.

[0045] A short-range communication module is for short-range communication and can support short-range communication by using at least one of Bluetooth™, RFID (Radio Frequency Identification), Infrared Data Association (IrDA), UWB (Ultra Wideband), ZigBee, NFC (Near Field Communication), Wi-Fi (Wireless-Fidelity), Wi-Fi Direct, and Wireless USB (Wireless Universal Serial Bus) technologies.

[0046] The location information module is a module for obtaining the location (or current location) of the electronic device (10) according to the present disclosure, and representative examples thereof include a GPS (Global Positioning System) module or a WiFi (Wireless Fidelity) module. For example, if a GPS module is utilized, the location of the electronic device can be obtained using signals sent from GPS satellites. As another example, if a WiFi module is utilized, the location of the electronic device (10) can be obtained based on information from a Wireless Access Point (AP) that transmits or receives wireless signals from the WiFi module. If necessary, the location information module may perform any of the functions of other modules of the communication module to obtain data regarding the location of the device, either substituted or additionally. The location information module is a module used to obtain the location (or current location) of the device, and is not limited to a module that directly calculates or obtains the location of the device.

[0047] The memory (130) can store various types of information. The memory can store data temporarily or semi-permanently. For example, the memory may store an operating system (OS) for operating the first device and / or the second device, data for hosting a website, or data regarding a program or application (e.g., a web application) for generating Braille. In addition, the memory may store modules in the form of computer code as described above.

[0048] Examples of memory (130) may include a hard disk drive (HDD), a solid state drive (SSD), flash memory, ROM (Read-Only Memory), and RAM (Random Access Memory). These memories may be provided as built-in or removable types.

[0049] The processor (140) controls the overall operation of the electronic device (100). To this end, the processor (140) performs computation and processing of various information and can control the operation of the components of the first device and / or the second device.

[0050] The processor (140) may be implemented as a computer or a similar device according to hardware, software, or a combination thereof. Hardware-wise, the processor (140) may be provided in the form of an electronic circuit that processes electrical signals to perform control functions, and software-wise, it may be provided in the form of a program that drives the hardware processor. Meanwhile, unless otherwise specifically mentioned in the following description, the operation of the first device and / or the second device may be interpreted as being performed by the control of the processor (140). That is, the modules may be interpreted as the processor (140) controlling the first device and / or the second device to perform the following operations.

[0051] The processor (140) may be implemented with a memory that stores data for an algorithm or a program that reproduces the algorithm for controlling the operation of components within the device, and at least one sub-processor (not shown) that performs the aforementioned operation using the data stored in the memory. In this case, the memory and the processor may each be implemented as separate chips. Alternatively, the memory and the processor may be implemented as a single chip.

[0052] In addition, the processor (140) can control one or a combination of the components described above in order to implement various embodiments according to the present disclosure, which will be described in FIGS. 2 to 7 below, on the device.

[0053] FIG. 2 is a block diagram illustrating a method for providing educational materials using an electronic device (100) that performs an operation of providing educational materials using a concept card according to one embodiment of the present disclosure, and FIG. 3 is a flowchart specifically illustrated.

[0054] At least one processor (140) of an electronic device (100) that performs an operation of providing educational materials using concept cards according to the present disclosure may be configured to provide a visual card in which sentences pre-set according to keywords are sequentially displayed based on the user interface, provide a voice corresponding to each sentence within the card together with the visual card based on the user interface, and when the provision of each sentence within the visual card and the voice corresponding to the sentence is completed, change a part of the sentence or add a new sentence within the visual card, and check whether the user input entered based on the user interface for the changed part of the sentence or the new sentence matches the correct answer.

[0055] As illustrated in FIG. 2, the electronic device (100) according to the present disclosure can perform an educational material provision operation method by performing an explanation step (S210), a verification step (S220), and a practice step (S230).

[0056] The explanation step (S210) is to explain the set educational keywords, such as the interrogative pronoun and infinitive of English grammar, by breaking them down into small sentences so that the student can easily understand them.

[0057] In the explanation step (S210), at least one processor (140) may provide the input / output module (110) with educational materials in the form of conversational text consisting of multiple sentences for a keyword, configured as concept cards.

[0058] In other words, the output module of the input / output module (110) can output sentences consisting of fewer than a preset number of words to the user screen for each sentence, output a main explanation of the concept, and, if necessary, output additional explanations such as examples or comments, distinguished from the main explanation.

[0059] In addition, as an embodiment, educational materials are configured in a conversational form so that the output module of the input / output module (110) outputs the main explanation and additional explanation sequentially, rather than outputting the entire sentence at once. Sequential output increases the learner's concentration on each sentence and allows the same level of concentration as in face-to-face learning to be maintained in non-face-to-face learning.

[0060] The above at least one processor (140) can output to the input / output module (110) a sentence composed of a preset number of words in the form of an interactive interface.

[0061] In this case, educational materials can be provided audiovisually by adding audio media that reads the sentences, in addition to outputting the sentences through visual media.

[0062] In other words, the concept can be presented as visual text, and the text can be played back as audio. Input through the user interface-based input / output module (110) can be controlled so that the learner can focus on the explanation until the audio playback is finished, and then input through the input / output module (110) can be controlled to be performed in the subsequent verification step (S220).

[0063] The verification step (S220) is a step for verifying whether the learner has properly understood the explanation in the explanation step (S210), and at least one processor (140) may perform the verification step (S220) after the explanation step (S210) for each concept card or for each sentence within a concept card.

[0064] In the explanation step (S210), specific words in the order sheet presented can be left blank to induce the user to input the correct answer through the input / output module (110), thereby checking the level of understanding and memorization. Additionally, actual example sentences or quizzes with specific concepts applied to the main explanation can be presented to verify sentences with applied concepts and aid in understanding.

[0065] At this time, the verification step (S220) may be performed after the corresponding explanation step (S210) is completed. For example, at least one processor (140) may control the input / output module (110) to output an example of the verification step (S220) or provide audio after all sentences corresponding to the explanation step (S210) and all audio for said sentences have been output, or to receive the correct answer for the quiz or the correct answer for the blanks. This is to induce the learner to watch or listen to the explanation step (S210) with concentration until the end.

[0066] In other words, after completing both the text output and the audio playback of the text, parts of the text can be changed to blanks or questions verifying memorization can be displayed. This is intended to prevent the problem of not understanding the entire explanation, which could arise if blanks were marked or questions were provided in advance, causing the user to focus only on the content to be entered or concentrate on solving the problems rather than the explanation.

[0067] If you fail to fill in the blanks or answer the question correctly, you can repeat the audio playback of the text until you fill in the blanks with the correct answer or answer the question correctly.

[0068] The practice step (S230) may be a step that enables the user to internalize the concept by repeating and providing the content performed in the explanation step (S210) and the verification step (S220). This is intended to enhance the learning effect through repetitive learning.

[0069] The practice stage (S230) displays and plays examples of the concept, and after the sentences in the examples end playback, it creates blanks in some of the content to induce user interface-based input. By creating the blanks after playback ends, learners are prevented from predicting the words where the blanks will appear in advance, thereby encouraging them to focus on the entire content.

[0070] In other words, the practice step (S230) is a step for repetitive learning and can be performed by repeating the process or configuration of the preceding explanation step (S210) and learning step (S220).

[0071] Additionally, the practice step (S230) is a step for repetitive learning, and the at least one processor (1400) may omit the practice step (S230) if it is determined that the difficulty of the concept is low or sufficient repetitive learning has been performed.

[0072] Specifically, the method for providing educational materials using concept cards according to the present disclosure can be performed by at least one processor (140) of the electronic device (100).

[0073] As illustrated in FIG. 3, the method may include the steps of: providing a visual card in which sentences pre-set according to keywords are sequentially displayed based on the user interface (S310); providing voice corresponding to each sentence within the card along with the visual card based on the user interface (S320); changing a part of the sentence or adding a new sentence within the visual card when the provision of each sentence within the visual card and the voice corresponding to the sentence is completed (S330); and checking whether user input entered based on the user interface for the changed part of the sentence or the new sentence matches the correct answer (S340).

[0074] Steps (S310) and (S320) may be identical or similar to the described step (S210) of FIG. 2.

[0075] Steps (S330) and (S340) may be identical or similar to the verification step (S220) of FIG. 2.

[0076] FIGS. 4 to 7 are screens illustrating a user interface of an electronic device (100) that performs an educational material provision operation using a concept card according to one embodiment of the present disclosure.

[0077] First, concept keywords to be learned can be guided along with a voice saying, "Shall we learn?" or "Listen carefully to the explanation and press Enter to proceed to the next step." As illustrated in FIG. 4, the sentence (41) "Shall we learn about the interrogative words who, whom, whose, and what today?" can be output to the input / output module (110) at the same time as the voice is output. The sentence (41) can present keywords that run through the entire concept card.

[0078] Then, example sentences may be read aloud, or explanations regarding the above examples or concepts may be provided. In this case, the explanation may be provided simultaneously with visual sentences and auditory sounds.

[0079] As illustrated in FIG. 4, example sentences (42) and explanatory texts (43, 44) corresponding to sentence (41) can be output. At this time, explanatory texts (43, 44) containing more important content can be output as an interface highlighted with a square.

[0080] Example sentence (42), which is less important than the explanatory text (43, 44), can be output in a form different from the explanatory text (43, 44).

[0081] In one embodiment, at least one processor (140) can output an explanatory text (43) to an input / output module (110) that reads, "First, an interrogative word is a word used to specifically ask about something you are curious about, and is placed at the beginning of a sentence," and can also output and play audio of the same content.

[0082] When playback is complete, as shown in FIG. 4, at least one processor (140) can change the word 'first', which is part of the sentence output to the input / output module (110), into a blank space.

[0083] At this time, if the user inputs 'first' based on the user interface, it can be output as described in the explanation (43).

[0084] Alternatively, as an example, at least one processor (140) may output an explanatory text (44) to the input / output module (110) that reads, “Since it asks for specific information such as ‘who’ or ‘what,’ it does not answer with Yes or No,” and may also output and play audio of the same content.

[0085] When playback is complete, as shown in FIG. 4, at least one processor (140) can change 'specific information', which is part of the sentence output to the input / output module (110), into a blank space.

[0086] At this time, if the correct answer, 'specific information,' is not entered based on the user interface, the audio of the explanatory text (44) can be played again to induce input based on the user interface. The audio of the explanatory text (44) contains 'specific information' and can serve as a hint if the user listens attentively.

[0087] As illustrated in FIG. 4, if the correct answer, 'specific information,' is not entered more than a preset number of times, a hint can be provided to the user. For example, a dotted line or gray text can be displayed inside the blank space.

[0088] Alternatively, the at least one processor (140) may be configured to provide the original sentence corresponding to the blank space translucently when the user input entered into the blank space exceeds a preset number of times and is not identical to the original sentence.

[0089] In one embodiment, at least one processor (140) may be configured to change a part of the sentence into a blank space at the same time as the completion of the provision of each sentence and voice within the visual card or within a preset time.

[0090] Additionally, the at least one processor (140) may be configured to provide voice corresponding to each sentence within the card based on the user interface if the user input entered into the blank space based on the user interface is not identical to the original sentence.

[0091] In one embodiment, at least one processor (140) may be configured to change the blank space so that it cannot be entered based on the user interface while the voice is being provided again, and to change the blank space so that it can be entered based on the user interface again when the voice is being provided is completed.

[0092] That is, at least one processor (140) can provide audiovisual explanations of English grammar based on concept cards containing explanatory text (43, 44) through an input / output module (110).

[0093] At least one processor (140) can provide sequential information, such as offline lectures, by providing each sentence sequentially rather than providing the entire explanatory text (43, 44) at once.

[0094] In addition, after the playback of the explanatory text (43, 44) is completed, a blank space or a quiz, additional explanation, and example sentences as shown in FIG. 5 can be provided to allow the learner to focus on the explanatory text (43, 44), and to test the memorized content after completing understanding and memorization.

[0095] As illustrated in FIG. 5, at least one processor (140) may output a verification step (S220 in FIG. 2) after an explanation step (S210 in FIG. 2), and may, for example, provide a subjective or objective quiz question (45) or provide additional explanatory text (46) required in the quiz question (45).

[0096] In the verification step (S220 of FIG. 2), blanks can also be provided as in the example (47) to induce the user interface-based blanks to be filled in.

[0097] As illustrated in FIG. 6, the example sentence (47) output to the input / output module (110) may include a sentence containing blanks, an example sentence in which words are arranged randomly and the word order can be selected, an example sentence in which words corresponding to a condition can be selected, and additional explanatory text.

[0098] Accordingly, the at least one processor (140) may be configured to newly output at least one of an example sentence corresponding to the previous sentence, an example sentence in which words included in the example sentence are randomly arranged, and a quiz question when the previous sentence and voice provision within the visual card is completed.

[0099] In addition, the above example sentence or part of the above quiz question is provided as a blank, and user input for the blank is received based on the above user interface, thereby allowing verification of whether the learner has completed memorization.

[0100] Meanwhile, the above at least one processor (140) may be configured to output the previous sentence and the example sentence or the quiz question so that they are visually distinguishable.

[0101] As shown in Fig. 6, the main explanatory text can be distinguished by printing the sentence within the highlighted box, while the quiz or example text can be distinguished by printing the sentence without the highlighted box.

[0102] In one embodiment, the at least one processor (140) may be configured to receive user input based on the user interface after voice provision corresponding to additional explanations for the example sentence and the quiz is completed, when the words included in the example sentence fail to sort the words of the randomly arranged example sentence or the quiz question is answered incorrectly.

[0103] When the explanation step (S210) and the verification step (S220) are completed, at least one processor (140) can output the problem score graded in the verification step (S220) or the problem score graded in the practice step (S230) to the input / output module (110).

[0104] As illustrated in FIG. 7, a first score is output, and if the first score is less than a preset score, for example, less than 80 points, the explanation step (S210), verification step (S220), or practice step (S230) can be repeated for relearning. After relearning, at least one processor (140) can output the problem score graded in the verification step (S220) or the problem score graded in the practice step (S230) to the input / output module (110) as a second score.

[0105] You can collect and check incorrect answers from the first or second round separately.

[0106] Accordingly, the electronic device (100) according to the present disclosure can change some words in the sentence into blanks after the visual sentence and auditory voice have been provided, and while the visual sentence and auditory voice are being provided, all pre-set main words are provided without being changed into blanks, and after the visual sentence and auditory voice have been provided, the blanks can receive user input through a user interface.

[0107] Learner concentration can be further enhanced by providing educational materials through audiovisual media and simultaneously performing an educational process that changes the form of the next sentence depending on the playback of each stage or its completion.

[0108] In addition, to check whether the explanation was heard properly, user input based on a user interface is provided in a visual sentence containing blanks, and if the user input differs from the correct answer, auditory voice may be repeatedly provided.

[0109] Learner concentration can be enhanced by providing visual sentences and auditory sounds sequentially, while simultaneously controlling the timing of text blank changes and the timing of receiving the correct answer for the blanks.

[0110] Meanwhile, the disclosed embodiments may be implemented in the form of a recording medium that stores instructions executable by a computer. The instructions may be stored in the form of program code and, when executed by a processor, may generate a program module to perform the operation of the disclosed embodiments. The recording medium may be implemented as a computer-readable recording medium.

[0111] Computer-readable recording media include all types of recording media that store instructions that can be decoded by a computer. Examples include ROM (Read Only Memory), RAM (Random Access Memory), magnetic tape, magnetic disk, flash memory, optical data storage devices, etc.

[0112] As described above, the disclosed embodiments have been explained with reference to the attached drawings. Those skilled in the art will understand that the present disclosure may be practiced in forms different from the disclosed embodiments without changing the technical spirit or essential features of the present disclosure. The disclosed embodiments are illustrative and should not be interpreted restrictively. Explanation of the symbols
