[0002] With the development of electronic whiteboard technology, they are gradually being applied to various fields, such as education. Electronic whiteboards are a teaching aid used by teachers. During daily lectures, they can display courseware and provide written explanations, which is very convenient. However, currently, the use of electronic whiteboards is limited to teachers. For example, teachers' evaluation of student performance in class relies on subjective evaluation, without technical solutions to utilize electronic whiteboards to assist in the evaluation, which is not conducive to accurate assessment. Summary of the Invention

[0003] The present application provides a method, apparatus, device, and storage medium for providing integral feedback of an all-in-one electronic whiteboard to address at least one of the problems in the related art. The technical solution is as follows:

[0004] In a first aspect, an embodiment of the present application provides a method for providing integral feedback of an all-in-one electronic whiteboard, comprising:

[0005] During the lecture, the electronic whiteboard is used to identify the lecture stage and to calculate the performance indicator set corresponding to each student in different lecture stages. The performance indicator set includes several performance indicators, including the number of times the electronic whiteboard is operated, the accuracy rate of answering questions, the time taken to respond, the number of times speaking, and the concentration score;

[0006] Adjust the basic weights of each performance indicator according to different teaching stages, and determine the dynamic weights of each performance indicator in different teaching stages;

[0007] Determine the stage score corresponding to each student in different lecture stages based on the performance indicator set corresponding to each student in different lecture stages and the dynamic weight corresponding to each performance indicator, and determine the total score corresponding to each student based on the stage score;

[0009] In one embodiment, identifying the lecture stage by using the electronic whiteboard integrated device includes:

[0010] The electronic whiteboard all-in-one device collects audio information and uses an audio recognition model to identify a first word in the audio information.

[0011] or,

[0012] The electronic whiteboard all-in-one device collects the courseware image currently displayed on the screen, performs text recognition on the courseware image, and obtains the second word. When the second word contains the preset trigger word corresponding to the lecture stage, it is determined that the corresponding lecture stage is currently entered.

[0013] In one embodiment, the statistical performance indicator set corresponding to each student in different lecture stages includes:

[0014] Different students can be distinguished through facial recognition at different stages of the lecture;

[0015] Count the number of times each student operates the electronic whiteboard all-in-one, count the total number of questions answered by each student and the number of correct answers, and determine the accuracy rate of each student's answers based on the ratio of the correct number to the total number;

[0016] Each time the teacher asks a question, the question time is recorded, as well as the student who spoke and the time when the student started speaking. The time interval between the speaking time and the question time is determined as the time for answering. Based on the recorded number of students who spoke, the number of times each student spoke is counted.

[0017] Through the posture recognition model, the listening postures of different students are identified, and the corresponding attention concentration score of each student is determined based on the listening posture.

The dynamic weights corresponding to the number of operations, the correct answer rate, the quick answer time, the number of speeches, and the concentration score in the listening stage are obtained. The dynamic weight corresponding to the concentration score is the largest.

[0020] When the lecture stage is the practice discussion stage, the basic weights corresponding to the number of operations and the number of speeches are increased, and the basic weights corresponding to the correct answer rate, the basic weights corresponding to the quick answer time, and the basic weights corresponding to the concentration score are reduced, and the dynamic weights corresponding to the number of operations, the correct answer rate, the quick answer time, the number of speeches, and the concentration score in the practice discussion stage are obtained;

[0024] Normalizing each performance indicator in the performance indicator set corresponding to each student in different lecture stages to obtain each normalized performance indicator;

[0025] According to the normalized performance indicators corresponding to each student in different teaching stages and the dynamic weights corresponding to each performance indicator, a weighted sum is performed to obtain the stage score corresponding to each student in different teaching stages.

[0026] In one embodiment, determining the total score corresponding to each student based on the scores at each stage includes:

[0027] Determine the duration of the lecture phase, the practice and discussion phase, and the review and consolidation phase, and determine the course length based on the sum of the duration of the lecture phase, the practice and discussion phase, and the review and consolidation phase;

[0028] Calculate the ratios of the duration of the lecture phase, the duration of the practice and discussion phase, and the duration of the review and consolidation phase to the course length, and obtain the first-stage coefficient of the lecture phase, the second-stage coefficient of the practice and discussion phase, and the third-stage coefficient of the review and consolidation phase.

[0029] The total score corresponding to each student is obtained by weighted summing up the stage integral of each student's listening stage, the first stage coefficient of the listening stage, the stage integral of the practice and discussion stage, the second stage coefficient of the practice and discussion stage, the stage integral of the review and consolidation stage, and the third stage coefficient of the review and consolidation stage.

[0031] Divide the screen of the electronic whiteboard into a lecture area and an integration area;

[0032] The points area displays the stage points and total points corresponding to each student in different teaching stages in real time, wherein the teaching area is used to display courseware.

[0033] In a second aspect, an embodiment of the present application provides an integral feedback device for an all-in-one electronic whiteboard, comprising:

[0034] A statistics module is used to identify the lecture stage through the electronic whiteboard during the lecture and to count the performance indicator sets corresponding to each student in different lecture stages.

[0040] The beneficial effects of the above technical solution include at least:

[0041] During the lecture, the electronic whiteboard all-in-one machine identifies the lecture stage and counts the performance indicators corresponding to each student in different lecture stages, such as the number of times the electronic whiteboard all-in-one machine is operated, the accuracy of the answers, the time for answering questions, the number of times speaking, and the concentration score. According to the different lecture stages, the basic weights corresponding to each performance indicator are adjusted, and the dynamic weights corresponding to each performance indicator in different lecture stages are determined, which more reasonably reflects the characteristics of different lecture stages; according to the performance indicator set corresponding to each student in different lecture stages and the dynamic weights corresponding to each performance indicator, the stage points corresponding to each student in different lecture stages are determined, and the total points corresponding to each student are determined based on the stage points.

[0047] Hereinafter, only certain exemplary embodiments are briefly described. As will be appreciated by those skilled in the art, the described embodiments may be modified in various ways without departing from the spirit or scope of the present application. Therefore, the drawings and description are to be regarded as illustrative in nature and not restrictive.

[0048] Reference Figure 1, showing a flow chart of a point feedback method for an electronic whiteboard integrated device according to an embodiment of the present application, the point feedback method for the electronic whiteboard integrated device may include at least steps S100-S400:

[0049] S100: During the lecture, the electronic whiteboard is used to identify the lecture stage, and the performance indicator set corresponding to each student in different lecture stages is counted.

[0050] Optionally, the performance indicator set includes several performance indicators, including the number of operations on the electronic whiteboard all-in-one device, the accuracy rate of answering questions, the time for answering questions, the number of times of speaking, and the concentration score.

[0051] S200: Adjust the basic weight corresponding to each performance indicator according to different teaching stages, and determine the dynamic weight corresponding to each performance indicator in different teaching stages.

[0052] S300. Determine the stage points corresponding to each student in different teaching stages based on the performance indicator sets corresponding to each student and the dynamic weights corresponding to each performance indicator, and determine the total points corresponding to each student based on the stage points.

[0053] S400, using the electronic whiteboard all-in-one to display in real time the corresponding stage points and total points of each student in different teaching stages.

[0054] The technical solution of the embodiment of the present application is to identify the teaching stage during the teaching process through the electronic whiteboard all-in-one machine, and count the performance indicators corresponding to each student in different teaching stages, such as the number of operations on the electronic whiteboard all-in-one machine, the accuracy of answering questions, the time for answering questions, the number of times speaking, and the attention concentration score. According to different teaching stages, the basic weight corresponding to each performance indicator is adjusted to determine the dynamic weight corresponding to each performance indicator in different teaching stages, so as to more reasonably reflect the characteristics of different teaching stages; according to the performance indicator set corresponding to each student in different teaching stages and the dynamic weight corresponding to each performance indicator, the stage score corresponding to each student in different teaching stages is determined, and the total score corresponding to each student is determined based on the stage score. The stage score and total score of different teaching stages are determined based on multiple performance indicators and dynamic weights, which is conducive to improving the comprehensiveness and accuracy of the evaluation; the stage score and total score corresponding to each student in different teaching stages are displayed in real time by the electronic whiteboard all-in-one machine, and the feedback display is conducive to stimulating students' enthusiasm.

[0055] In one embodiment, when a teacher uses an electronic whiteboard all-in-one machine to give a lecture, step S100 identifies the lecture stage through the electronic whiteboard all-in-one machine, including step S110 or S120:

[0056] S110. Collect audio information through the electronic whiteboard all-in-one machine, and identify the first word in the audio information through the audio recognition model. When the first word contains a preset trigger word corresponding to the lecture stage, determine that the current stage has entered the corresponding lecture stage.

[0057] Optionally, teachers can set preset trigger words for different teaching stages based on their own teaching habits. The specific trigger words set are not specifically limited. For example, for the listening stage, preset trigger word A is set, for the practice and discussion stage, preset trigger word B is set, and for the review and consolidation stage, preset trigger word C is set. In the embodiment of the present application, audio information is collected in real time by the electronic whiteboard all-in-one machine, and the first word in the audio information is identified by the audio recognition model. It is determined whether the current first word contains one of the preset trigger words A, B, and C, and the corresponding teaching stage is determined to be entered. For example, if the preset trigger word B is included, it is determined to enter the practice and discussion stage.

[0058] S120. Capture the courseware image currently displayed on the screen through the electronic whiteboard all-in-one machine, perform text recognition on the courseware image, and obtain a second word. When the second word contains a preset trigger word corresponding to the lecture stage, determine that the current stage has entered the corresponding lecture stage.

[0059] Alternatively, in some cases, the teacher may not verbally state the corresponding preset trigger word, but may trigger the class through text. For example, the teacher may have labeled the corresponding titles for each lecture stage in a pre-prepared PowerPoint presentation. The electronic whiteboard then captures the currently displayed presentation image and performs text recognition on the presentation image to obtain a second word. If the second word contains the preset trigger word for the corresponding lecture stage, the class is determined to have entered the corresponding lecture stage. For example, if the second word contains the preset trigger word C, the class is determined to have entered the review and consolidation stage.

[0060] In one embodiment, the step S100 of collecting statistics on the performance indicator sets corresponding to each student in different teaching stages includes steps S130-S160:

[0061] S130. During different lecture stages, different students are distinguished through face recognition.

[0062] Alternatively, an electronic whiteboard or an external camera connected to the electronic whiteboard can be used to capture the faces of different students and distinguish them using a facial recognition algorithm. It should be noted that because the above method can distinguish the specific stage of the current lecture, when the performance indicator set is subsequently obtained, the corresponding data will be recorded in the corresponding lecture stage, realizing automatic indicator statistics for each student at different lecture stages.

[0063] S140. Count the number of times each student operates the electronic whiteboard all-in-one, count the total number of questions answered by each student and the number of correct answers, and determine the accuracy rate of each student's answers based on the ratio of the correct number to the total number.

[0064] Optionally, the number of times each student operates the electronic whiteboard is counted (for example, when a student goes on stage to answer questions or give a lecture, he or she will touch and operate the electronic whiteboard, and each time he or she goes on stage to operate, the number of operations is recorded), and the total number of answers given by each student and the number of correct answers are counted. For example, after a student answers a question, the teacher will say "correct" or mark the correct answer with a "√" symbol on the screen. At this time, the number of correct answers given by the student can be automatically identified, and then the correct answer rate of each student can be determined based on the ratio of the correct number to the total number. In some implementation methods, since the number of answers in class is not particularly large, the teacher can also manually count the students' answers after they answer to determine the correct answer rate.

[0065] S150. Each time the teacher asks a question, the question time is recorded, as well as the student who speaks and the time when the student starts speaking. The time interval between the speaking time and the question time is determined as the time for answering. Based on the recorded number of students who speak, the number of speeches of each student is counted.

[0066] Optionally, the electronic whiteboard can record the time of each question asked by the teacher, that is, the moment when the question begins, and the student who spoke and the time when the student began speaking, determine the time interval between the speaking time and the question time as the time for answering, and count the number of speeches of each student based on the recorded number of students who spoke, that is, each speech of the student represents one speech. In some implementations, the teacher can also record manually.

[0067] S160. Identify the listening postures of different students through a posture recognition model, and determine the corresponding attention concentration score of each student based on the listening posture.

[0068] Alternatively, teachers can collect data on the listening postures of both attentive and distracted students, assigning different attention scores to each posture. This data can then be used as a training set to train a neural network model, generating a posture recognition model. This posture recognition model can then be used to identify the listening postures of different students and determine a corresponding attention score for each student based on their posture.

[0069] Therefore, the performance indicator set corresponding to each student in different teaching stages finally counted in the embodiment of the present application includes multiple performance indicators such as the number of operations on the electronic whiteboard all-in-one device, the accuracy rate of answering questions, the time for answering questions, the number of times speaking, and the concentration score.

[0070] In one embodiment, the sum of the dynamic weights corresponding to the performance indicators in different teaching stages is the same as the sum of the basic weights corresponding to the performance indicators, that is, the sum before and after adjustment is kept equal to 1. Step S200 includes steps S210-S230:

[0071] S210. When the lecture stage is the listening stage, the basic weight corresponding to the attention concentration score is increased, and the basic weight corresponding to the number of operations, the basic weight corresponding to the correct answer rate, the basic weight corresponding to the quick answer time, and the basic weight corresponding to the number of speeches are reduced, and the dynamic weights corresponding to the number of operations, the correct answer rate, the quick answer time, the number of speeches, and the attention concentration score in the listening stage are obtained. The dynamic weight corresponding to the attention concentration score is the largest.

[0072] It should be noted that, considering the characteristics of the listening stage, teachers usually introduce new knowledge points, so whether students listen attentively is the most important factor, that is, whether their attention is focused is the top priority. At the same time, students are less likely to answer questions or speak during this stage. Therefore, when the lecture stage becomes the listening stage, the basic weight corresponding to the attention score is increased accordingly, and the basic weights corresponding to the number of operations, the basic weight corresponding to the correct answer rate, the basic weight corresponding to the quick response time, and the basic weight corresponding to the number of speeches are reduced. Ultimately, the dynamic weights corresponding to the number of operations, the correct answer rate, the quick response time, the number of speeches, and the attention score in the listening stage are obtained. This maximizes the dynamic weight corresponding to the attention score, which is beneficial to improving the calculation accuracy of the stage score in the subsequent listening stage.

[0073] S220. When the lecture stage is the practice discussion stage, the basic weight corresponding to the number of operations and the basic weight corresponding to the number of speeches are increased, and the basic weight corresponding to the correct answer rate, the basic weight corresponding to the quick answer time, and the basic weight corresponding to the attention concentration score are reduced to obtain the dynamic weights corresponding to the number of operations, the correct answer rate, the quick answer time, the number of speeches, and the attention concentration score in the practice discussion stage.

[0074] It should be noted that during the practice discussion phase, students learn new knowledge and then discuss representative topics raised by the teacher based on what they have learned. Therefore, some students will express their own opinions on the electronic whiteboard, that is, operate on the electronic whiteboard, or express their opinions by raising their hands. Therefore, the number of operations and the number of speeches are the most prioritized factors. Therefore, when the lecture phase is the practice discussion phase, the basic weight corresponding to the number of operations and the basic weight corresponding to the number of speeches are increased, and the basic weight corresponding to the correct answer rate, the basic weight corresponding to the quick response time, and the basic weight corresponding to the concentration score are reduced. This gives the dynamic weights corresponding to the number of operations, the correct answer rate, the quick response time, the number of speeches, and the concentration score in the practice discussion phase.

[0075] S230. When the lecture stage is the review and consolidation stage, the basic weight corresponding to the correct answer rate and the basic weight corresponding to the quick answer time are increased, the basic weight corresponding to the number of operations is reduced, and the basic weight corresponding to the number of speeches and the basic weight corresponding to the attention concentration score are maintained, so as to obtain the dynamic weights corresponding to the number of operations, the correct answer rate, the quick answer time, the number of speeches and the attention concentration score in the review and consolidation stage.

[0076] It should be noted that, considering the characteristics of the review and consolidation phase, it is necessary to use the knowledge learned and the knowledge points summarized by the teacher after the discussion to further review and consolidate by answering questions. Therefore, answering questions is the most important factor. Therefore, when the lecture phase is the review and consolidation phase, the basic weight corresponding to the correct answer rate and the basic weight corresponding to the quick response time are increased, the basic weight corresponding to the number of operations is reduced, and the basic weight corresponding to the number of speeches and the basic weight corresponding to the concentration score are maintained. This gives the dynamic weights corresponding to the number of operations, correct answer rate, quick response time, number of speeches, and concentration score in the review and consolidation phase.

[0077] In one embodiment, step S300 determines the stage score corresponding to each student in different lecture stages based on the performance indicator sets corresponding to each student in different lecture stages and the dynamic weights corresponding to the performance indicators, including steps S310-S320:

[0078] S310 , normalizing each performance indicator in the performance indicator set corresponding to each student in different teaching stages to obtain each normalized performance indicator.

[0079] Optionally, since the statistical dimensions of each performance indicator in different performance indicator sets are different, a normalization function is first used to normalize each performance indicator in the performance indicator set corresponding to each student in different teaching stages to obtain each normalized performance indicator for subsequent calculations.

[0080] S320. Perform weighted summation based on the normalized performance indicators corresponding to each student in different teaching stages and the dynamic weights corresponding to the performance indicators to obtain the stage scores corresponding to each student in different teaching stages.

[0081] Optionally, weighted summation is performed based on the normalized performance indicators corresponding to each student in different teaching stages and the dynamic weights corresponding to each performance indicator, so as to obtain the stage points corresponding to each student in different teaching stages of listening stage, practice and discussion stage, and review and consolidation stage.

[0082] In one embodiment, step S300 determines the total score corresponding to each student based on the scores of each stage, including steps S330-S350:

[0083] S330. Determine the duration of the lecture phase, the duration of the practice and discussion phase, and the duration of the review and consolidation phase, and determine the course length based on the sum of the durations of the lecture phase, the practice and discussion phase, and the review and consolidation phase.

[0084] Optionally, since the teacher will allocate lecture time based on the importance of different stages, the length of different lecture stages can represent the importance of the corresponding stage points in the total points.

[0085] In the embodiment of the present application, since it is possible to determine which lecture stage to enter by using preset trigger words, the electronic whiteboard all-in-one machine can record the corresponding time when entering each lecture stage, so that the time length of the lecture stage, the time length of the practice and discussion stage, and the time length of the review and consolidation stage can be calculated based on each time, and the course length can be further determined based on the sum of the time length of the lecture stage, the time length of the practice and discussion stage, and the time length of the review and consolidation stage.

[0086] S340. Calculate the ratios of the duration of the lecture phase, the duration of the practice and discussion phase, and the duration of the review and consolidation phase to the course length, and obtain the first-stage coefficient of the lecture phase, the second-stage coefficient of the practice and discussion phase, and the third-stage coefficient of the review and consolidation phase.

[0087] Optionally, calculate the ratios of the length of time of the lecture stage, the length of time of the practice and discussion stage, and the length of time of the review and consolidation stage to the length of the course respectively, and use each ratio as the first stage coefficient of the lecture stage, the second stage coefficient of the practice and discussion stage, and the third stage coefficient of the review and consolidation stage. The size of the stage coefficient represents the importance of each lecture stage, and the larger the coefficient, the more important it is.

[0088] S350. Perform weighted summation based on each student's stage integral of the lecture stage, the first stage coefficient of the lecture stage, the stage integral of the practice and discussion stage, the second stage coefficient of the practice and discussion stage, the stage integral of the review and consolidation stage, and the third stage coefficient of the review and consolidation stage to obtain the total integral corresponding to each student.

[0089] Finally, the first-stage coefficient, the second-stage coefficient, and the third-stage coefficient are used as the weights corresponding to the listening stage, the practice and discussion stage, and the review and consolidation stage, respectively. Then, the weighted summation is performed according to each student's stage integral of the listening stage, the first-stage coefficient of the practice and discussion stage, the stage integral of the practice and discussion stage, the second-stage coefficient of the practice and discussion stage, the stage integral of the review and consolidation stage, and the third-stage coefficient of the review and consolidation stage to obtain the total integral corresponding to each student.

[0090] It should be noted that when determining the dynamic weights corresponding to the number of operations, answer accuracy, quick response time, number of speeches, and concentration scores in different lecture stages, the extent of the increase can be calculated based on the stage coefficient. Taking the practice discussion stage as an example, the stage coefficient corresponding to this lecture stage is the second-stage coefficient. To increase the basic weight corresponding to the number of operations and the basic weight corresponding to the number of speeches, the sum of the preset value and the second-stage coefficient is calculated, and then the product of this sum and the basic weight corresponding to the number of operations is calculated to obtain the dynamic weight corresponding to the number of operations. The product of this sum and the basic weight corresponding to the number of speeches is calculated to obtain the dynamic weight corresponding to the number of speeches. For example, the preset value is 1, the second-stage coefficient is 0.2, the sum is 1.2, and the basic weight corresponding to the number of operations is 25%. The dynamic weight corresponding to the number of operations is determined to be 30%. The dynamic weight corresponding to the number of speeches is calculated in a similar way. When the basic weight corresponding to the correct answer rate, the basic weight corresponding to the quick response time, and the basic weight corresponding to the concentration score are reduced, the sum of the reduced weights is the same as the increased part of the weights of the number of operations and the number of speeches, ensuring that the sum of all dynamic weights is 1. It can be understood that the dynamic weight adjustments in other lecture stages are similar and will not be repeated.

[0091] In one embodiment, step S400 includes steps S410-S420:

[0092] S410: Divide the screen of the electronic whiteboard into a lecture area and a scoring area.

[0093] In the embodiment of the present application, teachers can freely set the proportions of the lecture area and the integral area. The screen of the electronic whiteboard all-in-one is divided into two display areas, the lecture area and the integral area, based on the proportions.

[0094] S420. Display the corresponding stage score and total score of each student in different teaching stages in real time in the score area.

[0095] In an embodiment of the present application, the stage points and total points corresponding to each student in different lecture stages are displayed in real time in the points area, and the courseware is displayed in the lecture area, so that when the points are displayed, it does not affect the normal lecture, and students can see their own stage points and total points in real time, which encourages students to discuss and answer questions more actively, which is conducive to improving students' learning enthusiasm and enhancing teaching effectiveness.

[0097] A statistics module is used to identify the lecture stage through the electronic whiteboard during the lecture and to count the performance indicator sets corresponding to each student in different lecture stages.
