[0023] To make the objectives, technical solutions, and advantages of the present invention more clear, the technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0024] Currently, the evaluation of teachers' teaching quality relies primarily on on-site observation by experts, the subjective experience of reviewers, and the overall impression and subjective judgment formed by classroom teaching activities. However, this traditional evaluation model often only provides a general assessment of teachers' teaching level, and it is difficult to provide nuanced and multi-faceted feedback.

[0025] Specifically, the aforementioned evaluation model fails to fully consider a wide range of dimensions, including the depth and breadth of teaching content, the innovativeness and applicability of teaching methods, student engagement and interaction in class, and the level of tutoring and support provided by teachers after class. A comprehensive and in-depth evaluation of teachers' teaching performance requires the collection and in-depth analysis of detailed and specific teaching data from a wider range of channels. For example, this could include collecting information on students' homework completion, test scores, their willingness to answer questions in class, and their frequency of interaction in discussion forums.

[0026] However, collecting the above data will greatly increase the complexity and workload of the evaluation work, and may reduce the overall efficiency of the evaluation to a certain extent. In this regard, the present invention provides a teacher teaching scoring method, which aims to efficiently evaluate teacher teaching. Figure 1 It is a flow chart of the teacher teaching scoring method provided by the present invention, such as Figure 1 As shown, the method includes step 110 , step 120 and step 130 .

[0027] Step 110: Determine the course teaching audio of the teacher to be rated and the teacher rating scale. The teacher rating scale includes multiple observation points for rating the teacher's teaching ability.

[0028] Specifically, teachers to be evaluated are those currently requiring teaching evaluation. Course teaching audio refers to the audio data recorded during the classroom teaching process of the teacher to be evaluated. This audio data fully records the classroom conversations between teachers and students, the content of the lecture, and other audio information related to the teaching.

[0029] Among them, the course teaching audio can be directly recorded using professional audio acquisition equipment (such as high-sensitivity microphones, voice recorders, etc.) to obtain audio data independently, or you can choose to use video acquisition equipment to record the entire classroom teaching activities, and then extract the audio part from the recorded video data.

[0030] In addition, the teacher rating scale refers to a tool used to systematically and structuredly evaluate teachers' teaching performance. The teacher rating scale contains multiple observation points for scoring teachers' teaching abilities. Each observation point is used to measure teachers' teaching abilities from different evaluation dimensions. For example, the evaluation dimensions may include teaching content, teaching methods, teaching interaction, teaching effectiveness, teaching literacy, teaching objectives, etc.

[0031] For example, observation point 1, "Conformity with curriculum standards and curriculum reform concepts, emphasis on the cultivation of subject literacy," measures a teacher's teaching ability from the perspective of "teaching content." Observation point 2, "Conformity with students' actual needs, specific, structured, achievable, operational, and testable," measures a teacher's teaching ability from the perspective of "teaching objectives."

[0032] The teacher rating scale may be selected from existing scales, or a special scale may be customized according to teaching objectives, course content, and teacher evaluation requirements, which is not specifically limited in the embodiment of the present invention. Figure 2 is a schematic diagram of the teacher rating scale provided by the present invention, such as Figure 2 As shown in the figure, the first-level indicators refer to the highest-level classification dimensions for evaluating teachers' teaching abilities, which may include target evaluation, process evaluation, etc. The second-level indicators refer to more detailed evaluation dimensions under the first-level indicators, which are used to measure teachers' performance under the corresponding first-level indicators from different aspects. For example, the first-level indicator "process evaluation" can correspond to the second-level indicators "teacher activities" and student activities. The observation points are the evaluation dimensions under each indicator. For example, the observation point corresponding to "process evaluation"-"student activities" can be "paying attention to students' learning process and attaching importance to the cultivation of scientific literacy."

[0033] Step 120: Perform role separation and voice transcription on the course teaching audio to obtain the teacher-student dialogue text.

[0034] Specifically, course teaching audio usually contains the voices of teachers and students. In order to accurately analyze the classroom teaching situation, it is necessary to separate the voices of teachers and students in the course teaching audio (that is, to separate the roles), and to transcribe the audio after role separation to obtain the teacher-student dialogue text.

[0035] The teacher-student dialogue text refers to the text data containing the teacher-student dialogue content obtained after role separation and voice transcription. The teacher-student dialogue text not only records the content of the dialogue, but also marks the speaker of each sentence (teacher or student). An example of a teacher-student dialogue text is as follows: [Teacher]: Hello students, today we are going to learn a new chapter.

[0036] [Student A]: Teacher, how did you derive this formula? [Teacher]: This is a good question. The derivation process of this formula is... [Student B]: Teacher, I don’t quite understand... [Teacher]: It’s okay, let’s take another example... Alternatively, the course audio can be fed into a voiceprint recognition model, which identifies the voice characteristics of different speakers and segments the audio according to speaker roles, generating audio separated by roles. A speech recognition model is then used to transcribe the separated audio into text, generating the text of the teacher-student conversation. The voiceprint recognition model can be a Transformer model, and the speech recognition model can be a Conformer model.

[0037] Step 130: Based on the teacher-student dialogue text and the teacher rating scale, the rating model is applied to perform teacher rating, and the teaching rating and rating analysis of the teacher to be rated are obtained.

[0038] Specifically, teacher-student dialogue texts are authentic records of classroom teaching activities, encompassing the teacher's lecture content, questioning methods, interactions with students, responses to student questions, and more. Analyzing teacher-student dialogue texts allows for an objective understanding of a teacher's teaching behaviors and styles, providing a factual basis for teacher evaluations and avoiding reliance solely on subjective impressions.

[0039] The teacher rating scale is a pre-set evaluation system that clarifies the evaluation dimensions. It provides a unified and objective evaluation framework for the evaluation process, ensuring the consistency and comparability of the evaluation results.

[0040] In other words, the text of the teacher-student dialogue provides objective facts, and the teacher rating scale provides objective criteria. Combining these two in teacher ratings can reduce subjective bias and improve the objectivity of the evaluation. Furthermore, the teacher rating scale includes multiple observation points for evaluating teachers' teaching ability, allowing for assessments of teachers' teaching ability from different dimensions, achieving a comprehensive evaluation of their teaching.

[0041] Based on this, the embodiment of the present invention inputs the teacher-student dialogue text and the teacher rating scale into the rating model, and the rating model is used to rate the teacher to obtain the teaching rating and rating analysis of the teacher to be rated. Among them, the teaching rating refers to the result of a quantitative assessment of the teacher's teaching ability, usually presented in the form of a numerical value or grade, which is used to reflect the teacher's comprehensive performance in various evaluation dimensions. The rating analysis refers to a detailed explanation and description of the teacher's teaching rating, including the score of each evaluation dimension, the analysis of advantages and disadvantages, and the rating basis supporting the rating results. The rating analysis is intended to help teachers understand their own teaching strengths and weaknesses and provide a reference for teaching improvement.

[0042] For example, if the teaching score is 85 points (out of 100), the corresponding score analysis can be "Teaching content dimension: 90 points, the content is accurate and in-depth, and can effectively stimulate students' interest in learning. Teaching method dimension: 80 points, the methods are diverse, but some methods are not closely integrated with students' actual situations. Classroom interaction dimension: 85 points, teacher-student interaction is active, but student participation needs to be further improved, for example, more questioning methods or group activities can be tried. Scoring basis: In the 20-minute classroom recording, the teacher asked 15 questions and the students answered 8 times; the teacher used a variety of teaching methods such as heuristic questions and group discussions; the teaching content was highly consistent with the textbook content and appropriately expanded on related knowledge." Compared with the traditional method of mainly relying on the subjective experience of lecture experts or reviewers and their overall perception of classroom teaching to evaluate teachers' teaching, the embodiment of the present invention obtains the teacher-student dialogue text by role separation and voice transcription of classroom teaching audio, and combines it with the teacher rating scale and uses the rating model for automatic scoring, which can evaluate the teacher's teaching ability more objectively and comprehensively, reduce the interference of subjective factors, and improve the efficiency and accuracy of evaluation.

[0043] Among them, the scoring model can be a large language model (LLM, referred to as a large model). A large model refers to a natural language processing (NLP) model with a large parameter scale. The number of model parameters and / or the complexity of the model structure exceeds a preset threshold. The model processes large-scale text data during training and has the ability to understand and generate natural language.

[0044] As an optional embodiment, the scoring model can be trained based on the following steps: A large number of sample teacher-student dialogue texts and sample teacher rating scales are collected, and their corresponding teaching rating labels and rating analysis labels are determined through manual annotation. Subsequently, an initial model is trained based on the sample teacher-student dialogue texts, sample teacher rating scales, teaching rating labels, and rating analysis labels to obtain the scoring model.

[0045] Furthermore, by combining the text of teacher-student conversations with the teacher rating scale, it is possible to pinpoint problems teachers face during their teaching process and provide targeted suggestions for improvement, such as optimizing questioning techniques, adjusting teaching strategies, and designing more engaging classroom activities. For example, if a teacher scores low on the dimension of "classroom interaction," the text of the teacher-student conversation can be analyzed to identify the reasons for the lack of interaction, such as insufficient flexibility in the teacher's questioning style and low student engagement.

[0046] The teacher teaching scoring method provided in the embodiment of the present invention obtains the teacher-student dialogue text by role separation and voice transcription of classroom teaching audio, and combines it with the teacher scoring scale and uses the scoring model for automatic scoring. It can evaluate the teacher's teaching ability more objectively and comprehensively, reduce the interference of subjective factors, and improve the efficiency and accuracy of the evaluation.

[0047] Based on the above embodiment, based on the teacher-student dialogue text and the teacher rating scale, the rating model is applied to perform teacher rating, and the teaching rating and rating analysis of the teacher to be rated are obtained, including: Based on the teacher-student dialogue text, the scoring model is applied to analyze the course structure and obtain the course structure information; Based on the teacher rating scale, the rating model is applied to identify the observation point intention and obtain the teacher rating intention; Based on the course structure information and the teacher's scoring intention, the scoring model is applied to score the teacher and obtain the teaching score and scoring analysis of the teacher to be scored.

[0048] Specifically, given that teacher-student dialogue texts involve multiple teaching links, grading teachers based on these texts would make it difficult to distinguish the specific content related to each observation point, resulting in reduced grading accuracy and efficiency. For example, to assess whether a teacher "can effectively guide students to understand core concepts," it would be necessary to filter out explanations and interactions related to that concept from a large amount of dialogue text, which is time-consuming, labor-intensive, and prone to errors. Without parsing the course structure, the grading model may be interfered with by irrelevant information, resulting in inaccurate grading.

[0049] To this end, an embodiment of the present invention breaks down the teacher-student dialogue text into smaller units, such as knowledge points, concepts, examples, exercises, etc., to understand the overall structure and logical relationships of the course, so as to quickly locate the specific teaching content related to a certain observation point, avoid information redundancy and interference, and improve the accuracy and efficiency of scoring.

[0050] Based on this, an embodiment of the present invention applies a scoring model to teacher-student dialogue text to perform course structure analysis (i.e., breaking down the teacher-student dialogue text into smaller units) to obtain course structure information. Course structure information can be understood as a description of the organization and logical relationships of classroom teaching content, including the division of knowledge points, explanation of concepts, presentation of examples, arrangement of exercises, and the interrelationships and dependencies between them. In other words, course structure information is used to assist in understanding the overall framework of the course.

[0051] Furthermore, given that observation points in teacher rating scales are often described in general terms, the scoring model needs to convert these abstract descriptions into specific, executable instructions in order to automatically score. For example, the observation point "accuracy of teaching content" can be interpreted as "whether the teacher's explanation is consistent with the textbook" or "whether there are any errors in the teacher's explanation."

[0052] Based on this, the present invention uses a scoring model to identify the intent of observation points in the teacher rating scale. This method converts the abstract language descriptions of the observation points into specific, executable instructions, thereby obtaining the teacher's scoring intent. In other words, the teacher's scoring intent transforms abstract observation points into a series of clear, quantifiable evaluation criteria and indicators, guiding the scoring model on which teaching content and teaching behaviors to focus on, and how to make judgments and scores.

[0053] Because course structure information can quickly locate teaching content related to a particular observation point, the teacher's scoring intent can guide the scoring model to automatically analyze this content, thereby improving scoring efficiency. In other words, the embodiments of the present invention, combining course structure information with teacher scoring intent, can more efficiently and accurately match teachers' teaching behaviors with evaluation criteria, thereby achieving an objective and comprehensive assessment of teachers' teaching abilities.

[0054] Based on any of the above embodiments, the course structure information includes multiple course teaching links and their corresponding teacher teaching minutes; Based on the course structure information and the teacher's scoring intention, the scoring model is applied to the teacher to obtain the teacher's teaching score and scoring analysis, including: Based on the teacher's teaching minutes of each course teaching link and the teacher's grading intention, determine the teaching grading link from each course teaching link; Based on the teacher-student dialogue text, the scoring model is applied to score teachers in the teaching scoring link, and the teaching scores and scoring analysis of the teachers to be scored are obtained.

[0055] Specifically, course teaching links refer to the components of each course, representing the various stages that teachers go through to complete the teaching of the corresponding course. For example, a course may include an introduction, a new lesson, example questions, classroom exercises, classroom discussions, a summary, and homework assignments.

[0056] Furthermore, the teacher's teaching notes for a particular course segment provide a summary of the teacher's teaching activities during that segment. This can also be understood as a concise record of the teacher's teaching focus, methods, and interactions with students during that segment. For example, for the "introduction segment," the corresponding teacher's teaching notes might read, "The teacher reviews previous knowledge through questions, introducing new content."

[0057] Considering that not all teaching links are relevant to observation points, by analyzing teachers' teaching notes and their scoring intentions, we can filter out the teaching links (i.e., teaching scoring links) that are closely related to a specific observation point from each course teaching link. This narrows the scoring scope, avoids analyzing irrelevant teaching links, and improves scoring efficiency. In other words, teaching scoring links refer to the course teaching links that are closely related to the observation points in the teacher's scoring scale.

[0058] It can be seen that the embodiment of the present invention determines the teaching scoring links related to the evaluation objectives by breaking down the course into teaching links and combining the teacher's teaching minutes and the teacher's scoring intentions, thereby refining the granularity of the scoring and focusing the scoring on the teaching scoring links related to the observation points, thereby improving the efficiency, accuracy and pertinence of the scoring.

[0059] It should be noted that each step in the embodiments of the present invention can be implemented through a scoring model, or some steps can be implemented through a scoring model and some steps can be implemented through algorithmic analysis. For example, in the above steps, "based on the teacher's teaching minutes of each course teaching link and the teacher's scoring intention, determine the teaching scoring link from each course teaching link" can be implemented through rule matching or text similarity calculation, and "based on the teacher-student dialogue text, apply the scoring model to the teaching scoring link to obtain the teacher's teaching score and scoring analysis" can be implemented through a scoring model.

[0060] Based on any of the above embodiments, the teacher-student dialogue text is used to apply the scoring model to the teaching scoring link to score the teacher, and the teaching score and scoring analysis of the teacher to be scored are obtained, including: Based on the course teaching videos and teacher-student dialogue texts, the scoring model is used to conduct course retrospective and teaching analysis in the teaching scoring process to obtain the teacher's teaching situation; Based on the teacher's teaching situation, determine the teaching score and score analysis of the teacher to be scored.

[0061] Specifically, course teaching videos are videos that record the teacher's classroom teaching process. Course teaching videos can intuitively show the teacher's teaching behavior, such as the teacher's body language, facial expressions, and blackboard writing. This information is very important for understanding the teacher's teaching intentions and teaching effectiveness. Course teaching videos can be captured by using video capture equipment to record the entire classroom teaching process.

[0062] It should be noted that if the classroom teaching audio in the above embodiment is recorded independently by a professional audio acquisition device (such as a high-sensitivity microphone, voice recorder, etc.), and the course teaching video is obtained by recording with a video acquisition device, then the classroom teaching audio and classroom teaching video need to be time-aligned to ensure that the audio and video content are synchronized in time, so that the interaction between students, teaching content and teaching behavior can be correctly analyzed. However, the classroom teaching audio and course teaching video are collected by corresponding devices respectively, and time alignment is required, which not only wastes the collection cost but also has low efficiency. Based on this, the embodiment of the present invention preferably obtains the course teaching video by recording with a video acquisition device, and separates the course teaching audio from the course teaching video.

[0063] Considering that course teaching audio can only record sound information but not image information, course teaching video can make up for the lack of audio information. For example, course teaching video can show the teacher's blackboard content, demonstration process, etc.

[0064] In addition, the teacher-student dialogue text can record the detailed content of the teacher's explanation and the interaction with the students. The teacher-student dialogue text can assist in video analysis, such as quickly locating a key moment in the video through the text content. Course teaching videos provide intuitive teaching scenes, and teacher-student dialogue texts provide detailed teaching content. Combining the two can provide a more comprehensive understanding of the teacher's teaching behavior and teaching effect, and then can To this end, the embodiment of the present invention combines course teaching videos and teacher-student dialogue texts to conduct course retrospection and teaching analysis in the teaching scoring process to obtain the teacher's teaching situation, so as to understand the teacher's teaching level more accurately and comprehensively. Among them, the teacher's teaching situation refers to the summary and description of the teacher's teaching behavior and teaching effect in the teaching scoring process through course retrospection and teaching analysis. For example, the teacher's teaching situation can be "clear and easy to understand, and able to use vivid examples to explain abstract concepts", "questions can guide students to think, but fail to take into account students of different levels".

[0065] Course review refers to reviewing teachers' specific teaching behaviors during the teaching and assessment phase, such as how they explain key points, ask questions, and interact with students. Teaching analysis refers to evaluating the quality of teachers' teaching during the teaching and assessment phase, such as whether their explanations are clear and understandable, whether their questions stimulate students' thinking, and whether they can answer students' questions in a timely manner.

[0066] By analyzing a teacher's teaching performance, we can determine whether the teacher's performance on a certain observation point meets the scoring criteria. For example, if the teacher's teaching performance shows "clear and easy to understand", it can be judged that the teacher performed well on the observation point of "clear presentation of teaching content".

[0067] In addition, the scoring analysis needs to provide specific scoring basis. The teacher's teaching performance can serve as a basis for scoring and support the scoring results. For example, the following explanation can be used to explain why the teacher received a high score on the observation point of "clear presentation of teaching content": "The teacher's teaching performance shows that the teacher's explanations are clear and easy to understand, and he can use vivid examples to explain abstract concepts. This shows that the teacher has good communication skills and can effectively transfer knowledge." It can be seen that the embodiment of the present invention combines course teaching videos and teacher-student dialogue texts to conduct course retrospection and teaching analysis on the teaching scoring link, thereby obtaining the teacher's teaching situation, and can more comprehensively and objectively understand the teacher's teaching behavior and teaching effect in the teaching scoring link, provide a more reliable basis for subsequent teacher scoring, and generate a more convincing scoring analysis.

[0068] Based on any of the above embodiments, the teacher rating scale is determined based on the following steps: Determine the school district where the teacher to be evaluated is located, and obtain at least one of the teacher training plan, teacher evaluation direction, and teacher assessment requirements of the school district; Based on at least one of the teacher training plan, teacher evaluation direction, and teacher assessment requirements, the scoring model is applied to extract key information to obtain key information of teacher scores; Based on the key information of teacher ratings, observation points are refined to obtain multiple observation points for teacher teaching ability ratings.

[0069] Specifically, a teaching district refers to the school or educational institution where the teacher is located, such as a key middle school in a city, a rural primary school in a county, a vocational and technical college, or a college in a university. Different teaching districts may have different corresponding teaching objectives and evaluation standards. Therefore, embodiments of the present invention obtain at least one of the teacher training plan, teacher evaluation direction, and teacher assessment requirements of the teacher's teaching district, so that teacher evaluations are more consistent with the actual conditions and development needs of the teaching district.

[0070] The teacher training plan refers to a long-term development plan formulated to enhance teachers' professional qualities and teaching abilities. It may include training content, training objectives, training methods, and assessment requirements. Teacher evaluation focuses on key areas or aspects of evaluating a teacher's teaching performance, including teaching content, teaching methods, and teaching effectiveness. Teacher assessment requirements refer to the specific requirements and assessment standards for teachers' teaching work.

[0071] After obtaining at least one of the teacher training plan, teacher evaluation direction and teacher assessment requirements of the teacher's teaching district and school, key information is extracted based on the scoring model to obtain key information of teacher scoring. This teacher key information can be regarded as information with important reference value for evaluating the teacher's teaching ability.

[0072] Furthermore, considering that the key information for teacher ratings is usually the requirement for teachers' teaching ability, it is relatively general and abstract and difficult to use directly for evaluation. For example, the key information of "focusing on cultivating students' innovative spirit and practical ability" cannot directly guide how to evaluate whether teachers have achieved this. Observation points need to be specific, operational, and measurable to guide evaluation. For example, the key information for teacher ratings of "focusing on cultivating students' innovative spirit and practical ability" can be refined into the following observation points: "Are students encouraged to put forward different viewpoints and ideas in class?", "Are students provided with practical opportunities to apply knowledge to practice?", "Are students guided to engage in innovative thinking and research?" In other words, refining the observation points of key information for teacher ratings is to transform abstract requirements into specific, operational, and measurable evaluation indicators.

[0073] As an optional embodiment, when determining the teacher rating scale, it is also possible to receive text used to represent the user's customized needs, and perform intent recognition on the text to determine the aspects of the teacher's teaching ability that the user hopes to focus on, such as teaching interactivity, teaching content innovation, student participation, etc., and then determine multiple observation points for the teacher's teaching ability scoring based on the aspects of the teacher's teaching ability that the user hopes to focus on.

[0074] It can be seen that the embodiment of the present invention realizes the customization of the teacher rating scale by obtaining at least one of the teacher training plan, teacher evaluation direction and teacher assessment requirements of the teaching district and school, and extracting key information to refine the observation points, so as to make it more in line with the actual situation and development needs of the teaching district and school, and improve the pertinence and effectiveness of the evaluation.

[0075] Based on any of the above embodiments, based on the teacher-student dialogue text and the teacher rating scale, a rating model is applied to perform teacher rating, and a teaching rating and rating analysis of the teacher to be rated is obtained, which then includes: Generate grading invitations based on course teaching data and teacher grading scales; Receive expert ratings for each observation point based on user rating invitation feedback; Generate a score comparison chart based on each observation point in the teacher rating scale, the expert rating of each observation point, and the teaching rating and rating analysis of each observation point; A rating comparison chart is displayed.

[0076] Considering that the teaching ratings obtained based on the above-mentioned scoring model have a complete chain of evidence, strong logical connections, and high traceability, the scoring model may not be able to capture some subtle teaching details in the classroom (such as the teacher's eye contact), resulting in an incomplete teaching rating. In addition, while expert ratings can capture subtle teaching details in the classroom through teaching experts, their evaluation results are easily influenced by personal experience and experience. The heavy workload and lack of full attention may lead to a lack of accuracy in memory points and recorded data, which in turn may lead to subjectivity and uncertainty in the expert ratings.

[0077] Based on this, the embodiment of the present invention further obtains expert scores and generates a score comparison chart by combining the expert scores and the teaching scores, thereby integrating the objectivity of the teaching scores and the subtle insights of the expert scores to improve the accuracy, comprehensiveness and credibility of the evaluation.

[0078] Specifically, when obtaining expert ratings, a rating invitation is first generated based on the course teaching data and the teacher's rating scale. This rating invitation is a notification or request sent to users (such as teaching experts or reviewers) inviting them to rate the teacher's teaching. The rating invitation typically includes information such as the evaluation object (such as teacher and course information), the teacher's rating scale, and the rating entry point. The rating invitation can be in the form of a website link, QR code, app push, SMS push, WeChat official account push, etc.

[0079] Afterwards, users will provide expert ratings for each observation point based on the feedback from the rating invitation. The expert ratings here refer to the evaluations of teachers' teaching by teaching experts or reviewers with rich teaching experience and professional knowledge according to the observation points in the teacher rating scale, and the rating results given.

[0080] After obtaining the expert ratings, a rating comparison chart is generated based on each observation point in the teacher rating scale, the expert ratings of each observation point, and the teaching ratings and rating analysis of each observation point. In other words, the rating comparison chart contains information corresponding to each observation point, the expert ratings of each observation point, and the teaching ratings and rating analysis of each observation point.

[0081] Showing each observation point in a score comparison chart can comprehensively present a teacher's performance in different aspects; displaying expert scores can address potential shortcomings in teaching scores and provide a more nuanced evaluation perspective; displaying teaching scores can provide quantified results and traceable evidence; and displaying score analysis can help teachers understand the reasons behind the scores. Optionally, the score comparison chart can take the form of a bar chart, radar chart, line chart, or other similar format.

[0082] in, Figure 3 is a schematic diagram of the score comparison chart provided by the present invention, such as Figure 3 As shown in the figure, the AI score is the teaching score obtained based on the above-mentioned scoring model. The observation points, expert scores, AI scores and score analysis are displayed in the score comparison chart, which can more intuitively and comprehensively present the teacher's performance in different aspects, and help teachers understand the reasons behind the score, thereby promoting the professional development of teachers.

[0083] Based on any of the above embodiments, receiving the expert ratings for each observation point from the user based on the rating invitation feedback, further comprising: Generate a teacher rating report based on the expert ratings at each observation point, as well as the teaching ratings and rating analysis at each observation point; Based on the teacher rating report, or the teacher rating report and rating comparison chart, the teaching strategy of the teacher to be rated is generated.

[0084] Specifically, a teacher rating report is a written report that provides a comprehensive assessment of a teacher's teaching ability. Based on both teacher and expert ratings, it summarizes a teacher's strengths and weaknesses and provides suggestions for improvement. A teacher rating report can include basic information (such as the teacher's name and course title), an overall evaluation (e.g., an overall assessment of the teacher's teaching level), itemized evaluations (e.g., a detailed evaluation of the teacher across various evaluation dimensions), teaching rating results, expert rating results, and rating comparisons (e.g., a comparative analysis of teaching and expert ratings).

[0085] In addition, teacher strategies can be understood as action plans designated to improve teachers' level, which may include problem reflection (guiding teachers to reflect on the problems they encounter in the teaching process), teaching improvement (proposing specific improvement measures for the problems encountered by teachers in the teaching process), and teaching and research breakthroughs (encouraging teachers to participate in teaching research, explore new teaching methods and teaching models, and achieve teaching innovation).

[0086] As an optional embodiment, the teaching strategy of the teacher to be evaluated can be generated based on the teacher evaluation report. If the teacher scores low in the "classroom interaction" dimension and the teacher evaluation report indicates that his or her questioning style is relatively simple, the teacher can be advised to learn some new questioning skills and try to apply them in class.

[0087] As another optional embodiment, the teaching strategy of the teacher to be scored can be generated based on the teacher scoring report and the scoring comparison chart. If the scoring comparison chart shows that the teaching score is high in the "depth of teaching content", but the expert score is low, it may indicate that the teacher has a certain depth in knowledge explanation, but is lacking in guiding students to think deeply. It can be suggested that the teacher pay more attention to designing some questions that can stimulate students' thinking when preparing lessons.

[0088] Considering that the score comparison chart can more intuitively show the difference between teaching scores and expert scores, thereby providing more comprehensive information for formulating more targeted teaching strategies, the embodiment of the present invention preferably generates the teaching strategy of the teacher to be scored based on the teacher score report and the score comparison chart.

[0089] Based on any of the above embodiments, Figure 4 This is a flow chart of another method for teacher teaching scoring provided by the present invention, such as Figure 4 As shown, for online scenarios (i.e., online teaching), courses are recorded to obtain teacher course video data, and course audio data is extracted from the course video data. The course audio data is separated into roles and transcribed to obtain teacher-student dialogue text. Based on the teacher-student dialogue text, the course structure is analyzed to obtain teacher teaching minutes for each course teaching link. Teaching analysis is performed based on the teacher teaching minutes and the teacher rating scale to obtain teaching scores. At the same time, user expert scores are obtained for each observation point in the teacher rating scale. Based on the teaching scores and expert scores, a score comparison chart is generated. Based on the score comparison chart, the comparison between human and machine scores (i.e., the comparison between teaching scores and expert scores) can be clearly obtained. Then, based on the human and machine score comparison, a teacher rating report is generated. In addition, for offline scenarios (i.e., offline teaching), course evaluation data is collected, and a teacher rating report is generated based on the course evaluation data. Among them, all of the above steps can be implemented by the rating model.
