Description

Technical Field

[0001] This invention relates to the field of practical training and teaching technology, and in particular to a practical training and teaching and recording interactive system. Background Technology

[0002] Currently, some practical training and recorded video interactive systems on the market, although including both practical training modules and recorded video interactive modules, suffer from poor synergy between the two. For example, during practical training, students cannot easily access relevant recorded videos for reference, and while watching recorded videos, they cannot directly access the practical training interface for hands-on practice. This fragmentation between modules leads to the underutilization of teaching resources and affects teaching effectiveness. Furthermore, the data for practical training and recorded video interaction are stored in different systems, requiring teachers to log into different systems for management and operation, increasing their workload. Summary of the Invention

[0003] In view of this, the present invention proposes a practical training and recording interaction system, which can effectively solve the defects of the existing technology, such as the fragmentation between modules leading to the inability to fully utilize teaching resources, and the fact that the data of practical training and recording interaction are stored in different systems, requiring separate logins to different systems for management and operation.

[0004] The technical solution of this invention is implemented as follows:

[0005] A practical training and recording interactive system includes:

[0006] The practical training module is used for demonstrating practical operations, supervising students' practical training process, and managing practical training tasks.

[0007] The recording and playback interactive module is used to record, store, edit, and play back teaching videos;

[0008] The integration module is used to integrate the practical training module with the recorded interactive module, and the degree of integration between the practical training module and the recorded interactive module is evaluated through an integration degree calculation formula.

[0009] The interactive module is used to enable real-time or non-real-time interactive communication between practical training and recorded broadcasts at different times and locations.

[0010] As a further optional solution to the aforementioned practical training and recording interactive system, the practical training module includes:

[0011] The demonstration teaching unit is used to demonstrate practical training operations. The demonstration process is recorded and stored in the system resource library.

[0012] The operation inspection unit is used to monitor students' operation in real time during practical training.

[0013] The practical training task management unit is used to assign practical training tasks and record and manage practical training results.

[0014] As a further optional solution to the aforementioned practical training and recording interaction system, the recording interaction module includes:

[0015] The video recording unit is used to record practical training and theoretical explanation processes, generating teaching videos.

[0016] The video storage and management unit is used to store recorded teaching videos in the system resource library and to classify and manage them.

[0017] The video editing unit is used to edit the recorded teaching videos;

[0018] The video playback unit is used to play back the recorded teaching videos.

[0019] As a further optional solution to the aforementioned practical training and recording interactive system, the integration module includes:

[0020] The data interaction unit is used to realize data transmission and sharing between the practical training module and the recording and interactive module using a standardized data interface;

[0021] The functional collaboration unit is used to enable the practical training demonstration operation function, student practical training process inspection function, and practical training task management function in the practical training teaching module to work together with the teaching video recording, storage and editing functions in the recording and broadcasting interaction module based on the data transmitted by the data interaction unit through system integration technology.

[0022] The integration assessment unit is used to quantitatively evaluate the degree of integration between the practical training module and the recorded interactive module using an integration calculation formula.

[0023] As a further optional solution to the aforementioned practical training and recording interactive system, the integration degree calculation formula is as follows:

[0024] ;

[0025] Where C represents the degree of integration, It represents the collection of various functions in the practical training and teaching process. This represents a collection of functions for the recorded and interactive segments. This represents the contribution of cross-temporal and spatial interaction functions to the integration, with γ and δ being weighting coefficients.

[0026] As a further optional solution to the aforementioned practical training and recording interactive system, obtaining the contribution value of the cross-temporal and spatial interactive function to the integration specifically includes:

[0027] Collect cross-temporal and spatial interactive factors in the process of practical training and recorded interaction. The cross-temporal and spatial interactive factors include the frequency, duration and number of participants of real-time interaction, as well as the number of questions submitted, the number of replies and the number of effective interactions in non-real-time interaction.

[0028] The contribution value of cross-temporal and spatial interaction factors is calculated based on the contribution value calculation formula;

[0029] The specific formula for calculating the contribution value is as follows:

[0030] ;

[0031] This represents the contribution of the cross-temporal and spatial interaction function to the integration, where n is the number of cross-temporal and spatial interaction factors that influence the contribution value. Let be the weight coefficient of the j-th intertemporal interaction factor, used to reflect the importance of this factor in the overall contribution. This is the numerical index after quantification of the j-th cross-temporal interaction factor.

[0032] As a further optional solution to the aforementioned practical training and recording interactive system, the system also includes a user management module for authenticating, assigning permissions, and managing information for different user roles.

[0033] A practical training and recording interaction method, wherein the method applies any of the above-described practical training and recording interaction systems.

[0034] The beneficial effects of this invention are as follows: The practical training module undertakes the function of demonstrating practical operations, while the recording and interactive module realizes functions such as recording teaching videos. When teachers assign practical training tasks, they can link relevant recorded video resources. After completing the practical training tasks, students can submit their results in the form of videos, documents, etc. The recording and interactive module can store these results and link them to the practical training tasks. Teachers can evaluate students' task results based on the recorded videos, and other students can also learn and exchange ideas by watching the result videos, promoting the sharing and utilization of teaching resources and solving the defect of existing technologies where the separation between modules leads to the inability to fully utilize teaching resources. Furthermore, the integration module combines the practical training module and the recording and interactive module... The data is integrated to build a unified data storage platform. All data related to practical training and recorded interactive sessions are stored on this unified platform. Teachers and students only need to log in to one system to access and manage all relevant data without switching between different systems, which improves work efficiency and solves the shortcomings of existing technologies where practical training and recorded interactive sessions are stored on different systems, requiring separate logins for management and operation. In addition, the integration module evaluates the degree of integration between the practical training module and the recorded interactive session module through an integration degree calculation formula. By analyzing the integration degree index, the collaborative work between modules can be understood, existing problems and deficiencies can be identified, and the overall performance and stability of the system can be improved.

[0040] The technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0041] refer to Figures 1 to 4 A practical training and recording interactive system includes a practical training module, a recording interactive module, an integration module, and an interactive module.

[0042] The practical training module is used for demonstration operations. Teachers can demonstrate through the system via live streaming or pre-recorded videos. It also allows teachers to monitor students' practical training process, supporting them to view students' operation status through remote monitoring and real-time data feedback, and provide timely guidance. The module manages practical training tasks, including the entire process of task release, submission, grading, and grade recording.

[0043] In some embodiments, the practical training module includes:

[0044] The demonstration teaching unit is used to demonstrate practical training operations. The demonstration process is recorded and stored in the system resource library.

[0045] The operation inspection unit is used to monitor students' operation in real time during practical training.

[0046] The practical training task management unit is used to assign practical training tasks and record and manage practical training results.

[0047] Specifically, teachers can conduct practical training demonstrations through live streaming or pre-recorded videos. Live demonstrations allow teachers to interact with students in real time, answer questions, and create a learning atmosphere that is close to a real classroom. Pre-recorded videos allow teachers to carefully record demonstration content to ensure that the operation steps are clear and accurate. Students can pause and replay the video at any time to watch key operation steps repeatedly, deepen their understanding and mastery of knowledge, and improve learning outcomes.

[0048] It supports teachers to remotely monitor students' practical training process and view students' operation status through real-time data feedback. This enables teachers to promptly identify errors or problems that students encounter during operation and provide timely guidance, preventing students from developing bad habits that will affect their subsequent learning, ensuring the accuracy of students' practical training operations, and improving the quality of practical training teaching.

[0049] The system covers the entire process of practical training task release, submission, grading, and grade recording. Teachers can easily release practical training tasks in the system, specifying task requirements and objectives; students can submit practical training results online, and the system automatically records information such as submission time; teachers can grade assignments and record grades online, reducing the cumbersome process of traditional paper-based assignment collection, grading, and grade registration, and greatly improving the efficiency of teaching management.

[0050] The demonstration teaching unit records and stores the demonstration process in the system resource library, forming a wealth of teaching resources. These resources can not only be used for students to review and consolidate their learning after class, but also serve as a reference for subsequent teaching. New teachers can learn from excellent teaching demonstration videos to conduct their own teaching, thereby achieving effective integration and reuse of teaching resources and reducing teaching costs.

[0051] By reviewing students' practical training videos and results, combined with real-time data feedback, teachers can more comprehensively and accurately assess students' performance during the training process, including their mastery of operational skills and problem-solving abilities. This helps teachers identify students' strengths and weaknesses, providing a basis for personalized teaching.

[0052] The recording and interactive module is used to record teaching videos. It supports automatic recording (recording starts automatically according to the preset teaching schedule) and manual recording (teachers can control the start and end of recording). Recorded videos are stored in the system resource library. Videos can be edited, such as trimming, adding subtitles, highlighting key points, etc., and students can replay the videos for learning. Students can replay the videos anytime and anywhere according to their own needs.

[0053] In some embodiments, the recording and playback interaction module includes:

[0054] The video recording unit is used to record practical training and theoretical explanation processes, generating teaching videos.

[0055] The video storage and management unit is used to store recorded teaching videos in the system resource library and to classify and manage them.

[0056] The video editing unit is used to edit the recorded teaching videos;

[0057] The video playback unit is used to play back the recorded teaching videos.

[0058] Specifically, it supports two recording modes: automatic recording (which starts and ends automatically according to the preset teaching schedule) and manual recording (which teachers can control to start and end the recording). Automatic recording is suitable for regular teaching scenarios, such as practical training with fixed time and fixed courses, which can ensure the complete recording of the teaching process and reduce the teacher's workload. Manual recording gives teachers more control in special situations: for example, when teachers add important explanation content or demonstration operations on the spot, they can start recording independently to ensure that key teaching information is not missed, which improves the flexibility and adaptability of video recording.

[0059] The video storage and management unit stores the recorded teaching videos in the system resource library and manages them by category. This allows a large number of teaching videos to be saved and organized in an orderly manner, making it convenient for teachers and students to quickly find and access the videos they need. For example, they can be classified according to course name, teaching chapter, recording time, etc., which improves the efficiency of resource management and avoids the chaos and loss of video resources.

[0060] The video editing unit allows for editing, adding subtitles, and highlighting key points in recorded teaching videos. Teachers can personalize the videos according to their teaching needs, removing unnecessary segments to make the teaching content more concise and prominent. Adding subtitles can help students better understand the content while watching the video, especially in the presence of noise or when the teacher has a strong accent. Highlighting key points can guide students to focus on key knowledge points and improve learning outcomes.

[0061] The video replay unit allows students to review videos for learning. Students can replay videos anytime and anywhere according to their own needs, which provides students with flexible learning time arrangements. Students can review and consolidate classroom content after class, or watch the videos repeatedly for parts they do not understand, meeting the learning pace and needs of different students. For example, if a student is not familiar with a certain step after a practical operation, they can replay the video to learn the operation method of that step again.

[0062] The integration module is used to integrate the practical training module with the recording and interactive module. It uses data interface docking, system integration and other technical means to realize data interaction and functional collaboration between the two modules.

[0063] In some embodiments, the integration module includes:

[0064] The data interaction unit is used to realize data transmission and sharing between the practical training module and the recording and interactive module using a standardized data interface;

[0065] The functional collaboration unit is used to enable the practical training demonstration operation function, student practical training process inspection function, and practical training task management function in the practical training teaching module to work together with the teaching video recording, storage and editing functions in the recording and broadcasting interaction module based on the data transmitted by the data interaction unit through system integration technology.

[0066] The integration assessment unit is used to quantitatively evaluate the degree of integration between the practical training module and the recorded interactive module using an integration calculation formula.

[0067] Specifically, the data interaction unit adopts a standardized data interface, enabling efficient and accurate data transmission and sharing between the practical training module and the recording and interactive module. The standardized interface ensures seamless data exchange between different modules, avoiding transmission errors or data loss caused by incompatible data formats. For example, student training operation data recorded in the practical training module can be successfully transmitted to the recording and interactive module, providing a foundation for subsequent video association and analysis. Through the standardized data interface, data between the two modules can maintain real-time synchronization. When data in the practical training module changes, such as when teachers modify training task information, the recording and interactive module can promptly obtain these updates, ensuring data consistency between the two modules. This ensures that teachers and students receive the latest and most accurate information in both the practical training module and the recording and interactive module, improving the efficiency of teaching management and the scientific nature of decision-making.

[0068] Based on the data transmitted by the data interaction unit, the functional collaboration unit utilizes system integration technology to enable the practical training demonstration operation function, student training process inspection function, and practical training task management function in the practical training teaching module to coordinate with the teaching video recording, storage, and editing functions in the recording and broadcasting interaction module. For example, during the practical training demonstration operation, the recording and broadcasting interaction module can automatically start recording to fully record the teacher's demonstration operation. When the teacher inspects the student training process, the relevant inspection data can be correlated with the student's practical operation video, facilitating subsequent comprehensive analysis by the teacher. Functional collaboration expands the teaching application scenarios and brings more possibilities to teaching. For example, by combining the practical training task management function and video editing function, teachers can create corresponding teaching video resource packages for different practical training tasks. Students can watch relevant videos in a targeted manner according to the task requirements to achieve more precise learning. At the same time, functional collaboration also makes the teaching process smoother, reduces the operational inconvenience caused by switching between different modules, and improves the user experience.

[0069] The integration assessment unit uses an integration calculation formula to quantitatively evaluate the degree of integration between the practical training module and the recorded interactive module. This quantitative assessment can objectively reflect the collaborative work between the two modules and provide a clear basis for system optimization and improvement.

[0070] It should be noted that the functional coordination unit includes:

[0071] Triggering the linkage sub-unit:

[0072] It has a practical training demonstration trigger recording function. When the teacher starts the practical training demonstration operation in the practical training teaching module, this sub-unit automatically sends a trigger signal to the recording and interactive module to start the recording of the teaching video and record key information such as the start time of the demonstration operation and the operation topic to ensure that the demonstration process is completely recorded.

[0073] The system includes a task posting and recording function. When a teacher posts a practical training task in the practical training module, the recording and recording interaction module is triggered to generate a recommended list of teaching videos related to the task. Teaching videos closely related to the task's knowledge points and operational points are pushed to students participating in the practical training, making it convenient for students to preview or review relevant knowledge in advance.

[0074] Includes a monitoring and recording function. When teachers monitor students' training process in the practical training module, if they find any questions or errors in the students' operations, this sub-unit can quickly call up the corresponding recorded video clips in the recording and interactive module, such as the standard demonstration video of the operation steps, and show them to the students in real time to assist teachers in providing on-site guidance.

[0075] Functional integration presentation sub-unit:

[0076] The system interface integrates the practical training and recording interaction functions, and integrates the operation interface of practical training and the recording video playback window into a single layout. For example, a split-screen display is used, with the practical training operation interface on the left and the recording video playback window on the right, so that teachers and students can perform practical training operations and watch teaching videos on the same interface at the same time.

[0077] It provides a quick function switching button, which allows users to quickly switch between practical training functions (such as demonstration operation, task management, etc.) and recording and interactive functions (such as video recording, playback, etc.) by clicking the button, thereby improving the efficiency of teaching and learning;

[0078] It supports comprehensive analysis and visualization of data related to practical training and recorded video interaction. For example, it can generate charts containing practical training data and recorded video learning data, intuitively presenting information such as students' learning progress, operational proficiency, and video learning effects, providing teachers with comprehensive teaching evaluation basis.

[0079] In some embodiments, the integration degree calculation formula is specifically as follows:

[0080] ;

[0081] Where C represents the degree of integration, It represents the collection of various functions in the practical training and teaching process. This represents a collection of functions for the recorded and interactive segments. This represents the contribution of cross-temporal and spatial interaction functions to the integration, with γ and δ being weighting coefficients.

[0082] Specifically, in the formula It represents the collection of various functions in the practical training and teaching process. This represents a collection of functions for the recorded and interactive segments, through... This item comprehensively considers the functions of both modules. It assesses the interrelationship and synergy between practical training functions (such as demonstration operation, inspection process, and task management) and recording and broadcasting interactive functions (such as video recording, storage, editing, and playback). For example, when the demonstration operation function in practical training and the video recording function in recording and broadcasting interactive functions work closely together, this item's value will be relatively high, reflecting good integration between the functions. The calculation method reflects the interaction between two sets of functions. Different combinations of functions will produce different synergistic effects. This formula can capture these complex interactive relationships. For example, the function of inspecting students' training process in practical teaching is combined with the real-time video playback function in recording and broadcasting interaction. Teachers can more accurately inspect the details of students' operation by playing back the video. This functional interaction is reflected in the formula, which helps to accurately evaluate the integration effect.

[0083] In the formula The article emphasizes the contribution of cross-temporal and spatial interaction functions to the integration. Cross-temporal and spatial interaction (such as real-time or non-real-time interactive communication at different times and locations) plays an important role in modern teaching. This formula incorporates it into the integration evaluation system, highlighting the value of interactive functions in module integration. For example, students can use the system to conduct non-real-time interactive communication with teachers after class to solve problems encountered in practical training. This kind of interaction has a positive impact on teaching effectiveness, and the formula can quantitatively evaluate it.

[0084] The integration degree C is calculated using a formula to arrive at a specific numerical value that objectively measures the degree of integration between the practical training module and the recorded interactive module. This value can intuitively reflect the integration effect between the two modules, avoiding the ambiguity and uncertainty of subjective evaluation. For example, by comparing the integration degree values ​​under different time periods or different teaching scenarios, the changing trend of system integration can be clearly understood.

[0085] In some embodiments, obtaining the contribution value of the cross-temporal and spatial interaction function to the integration specifically includes:

[0086] Collect cross-temporal and spatial interactive factors in the process of practical training and recorded interaction. The cross-temporal and spatial interactive factors include the frequency, duration and number of participants of real-time interaction, as well as the number of questions submitted, the number of replies and the number of effective interactions in non-real-time interaction.

[0087] The contribution value of cross-temporal and spatial interaction factors is calculated based on the contribution value calculation formula;

[0088] The specific formula for calculating the contribution value is as follows:

[0089] ;

[0090] This represents the contribution of the cross-temporal and spatial interaction function to the integration, where n is the number of cross-temporal and spatial interaction factors that influence the contribution value. Let be the weight coefficient of the j-th intertemporal interaction factor, used to reflect the importance of this factor in the overall contribution. This is the numerical index after quantification of the j-th cross-temporal interaction factor.

[0091] Specifically, the solution collects cross-temporal and spatial interaction factors during practical training and recorded interactive sessions, covering multiple dimensions such as the frequency, duration, and number of participants in real-time interactions, as well as the number of questions submitted, the number of replies, and the number of effective interactions in non-real-time interactions. This comprehensive collection of factors can accurately reflect the actual situation of cross-temporal and spatial interactions and avoid the one-sidedness of single-factor evaluation. For example, situations such as high frequency of real-time interactions but low number of participants, or many questions submitted but few replies in non-real-time interactions, can be reflected through comprehensive consideration of multi-dimensional factors, thereby more accurately evaluating the interaction status.

[0092] The contribution value of cross-temporal and spatial interaction factors is calculated based on a specific contribution value calculation formula, which introduces weighting coefficients. and quantified numerical indicators This method can scientifically quantify the contribution of various cross-temporal and spatial interactive factors to the integration. The weighting coefficients reflect the importance of different factors in the overall contribution. For example, the frequency of real-time interaction may be more important than the number of participants in certain teaching scenarios. By reasonably setting the weighting coefficients, the calculation of the contribution value can be more in line with the actual situation. The weighting coefficients in the formula... The evaluation criteria can be dynamically adjusted according to different teaching needs and scenarios. If more emphasis is placed on the effect of non-real-time interaction in teaching reform, the weight coefficient of non-real-time interaction-related factors can be appropriately increased, thereby flexibly adjusting the evaluation criteria so that the evaluation results can better serve the teaching objectives.

[0093] It should be noted that the numerical indicators obtained after quantifying the aforementioned cross-temporal and spatial interaction factors are... The specific steps include:

[0094] Data preprocessing steps:

[0095] Data cleaning: Through preset data verification rules, outliers and missing values ​​in cross-temporal and spatial interaction data are identified and removed; for outliers, such as negative real-time interaction durations or values ​​far exceeding the reasonable range, they are marked and removed from the dataset; for missing values, if the data item is key information and the missing ratio is less than a preset threshold (e.g., 5%), it is filled using the mean imputation method based on similar interaction scenario data; if the missing ratio exceeds the threshold, the data record containing the missing value is deleted.

[0096] Data standardization: Transform cross-temporal and spatial interactive data with different dimensions and units to the same scale; For data such as real-time interaction frequency (unit: times / time period) and real-time interaction duration (unit: minutes), use linear transformation standardization method to map the data to the [0,1] interval;

[0097] Steps for quantifying interactive metrics:

[0098] Quantification of Real-Time Interaction Metrics: Calculate the real-time interaction frequency metric by counting the number of real-time interactions between different participants (teachers and students, students and students) within a specific time period (e.g., one day, one week), using this as a quantified value for the real-time interaction frequency. Determine the average real-time interaction duration metric by recording the duration of each real-time interaction and calculating the average of all real-time interaction durations to measure the depth of the interaction. Quantify the real-time interaction participation metric by counting the proportion of participants in the real-time interaction to the potential participants. Potential participants are the total number of people who should participate in the interaction within a specific time period, reflecting the coverage of the interaction.

[0099] Quantification of Non-Real-Time Interaction Metrics: This includes: Statistical analysis of the number of effective non-real-time interactions. Based on pre-defined rules for determining effective interaction, a student's question is counted as one effective interaction if it receives a valuable response from a teacher or other student and the question is resolved. The total number of effective interactions within a specific time period is recorded. Calculation of Non-Real-Time Interaction Response Time Metrics: For student-submitted questions or messages, the time interval from submission to receiving the first response is recorded. The average of all response intervals is calculated as the quantified value of the non-real-time interaction response time, reflecting the timeliness of the interaction. Quantification of Non-Real-Time Interaction Content Quality Metrics: Natural language processing technology is used to analyze the response content in non-real-time interactions, evaluating the completeness, accuracy, and usefulness of the response content and assigning a corresponding quality score ranging from 0 to 10 points to measure the quality of the interaction content.

[0100] Comprehensive quantification processing steps:

[0101] Weights are assigned to each quantitative indicator. Based on the importance of cross-temporal and spatial interaction in different teaching scenarios, the weight coefficients are determined by expert scoring or entropy weighting based on historical data analysis. For example, in training scenarios that emphasize real-time guidance, the weight of real-time interaction indicators is relatively high.

[0102] Based on the assigned weights, a weighted summation method is used to calculate the comprehensive quantitative value of cross-temporal and spatial interaction.

[0103] The interactive module enables real-time or non-real-time interactive communication between practical training and recorded videos at different times and locations. Real-time interaction includes voice calls, video conferencing, and text chat rooms, supporting instant communication between teachers and students, and among students themselves, during practical training and video learning. Non-real-time interaction includes students submitting questions and leaving messages while watching recorded videos, with teachers or other students responding at appropriate times. The system records and organizes the interactive content for easy review later.

[0104] In some embodiments, the interactive module includes:

[0105] The real-time interactive unit supports real-time voice and video communication between teachers and students, and between students, during practical training and recorded learning, as well as interactive forms such as text chat and Q&A.

[0106] In the non-real-time interactive units, students can submit questions and leave messages while watching pre-recorded videos, and teachers or other students can respond at appropriate times. At the same time, the system supports recording and organizing the interactive content for easy review later.

[0107] The user management module performs identity authentication, permission allocation, and information management for different user roles such as teachers and students, ensuring that different users can use the various functions of the system according to their permissions, and guaranteeing the security and orderliness of cross-time and space interaction.
