Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of teaching materials, in particular to a loose-leaf teaching material construction and operation management system for vocational education. BACKGROUND

[0002] Teaching materials are materials used by teachers and students for teaching and learning, which are prepared according to curriculum standards and reflect the teaching content of a subject. Teaching materials are usually divided into volumes according to school years or semesters, units or chapters, and their content can be the main part of textbooks, or can include exercise books, activity books, story books, supplementary exercises, tutoring materials, audio tapes, video tapes, computer discs, newspapers and magazines, radio and television programs, slides, photos, cards, etc. Teaching materials not only include officially published books, but also all teaching materials used in the classroom and outside the classroom, such as learning materials used on computer networks. The definition of teaching materials has broad and narrow meanings. Broadly speaking, teaching materials refer to all teaching materials used by teachers and students in the classroom and outside the classroom, and any material that helps learners to increase their knowledge or develop their skills can be called a teaching material. Narrowly speaking, teaching materials mainly refer to textbooks, which are the core teaching materials of a course. In the field of vocational education, the traditional teaching material development method usually uses manual management, which is inefficient and cannot meet the needs of both the companies that develop the teaching materials and the schools that use the teaching materials, making it difficult to adapt to the flexibility of vocational education. In addition, the traditional teaching material development and management process lacks effective monitoring and evaluation mechanisms, making it difficult to ensure the quality and teaching level of the teaching materials. Therefore, teaching materials need to be changed to loose-leaf teaching materials.

[0003] Traditional teaching materials mostly construct teaching content based on a knowledge system, emphasizing the systematicness, completeness and coherence of the knowledge system, and cultivating students to have a solid theoretical foundation. Loose-leaf teaching materials usually organize teaching based on individual tasks and connect the tasks in the form of loose-leaf, emphasizing practice and application based on the understanding and mastery of knowledge, and cultivating students to have strong practical ability based on a certain theoretical foundation. Loose-leaf teaching materials are suitable for student-centered teaching modes and reflect the deep interaction between teaching materials and learners under the premise of student-centeredness. In the process of cultivating high-quality technical and skilled talents in higher vocational colleges, the "three teachings" reform, which takes teachers, teaching materials and teaching methods as the core, is the core of educational and teaching reform. The development of loose-leaf teaching materials and the construction of teaching resources are effective forms and carriers of teaching reform, and play an important role in promoting the cultivation of high-quality technical and skilled talents.

[0027] In order to deepen the understanding of the present application, the present application will be further described below in conjunction with examples, which are only used to explain the present application and do not constitute a limitation on the protection scope of the present application.

[0028] Example one

[0029] According to Figure 1 , 2 , 3, 4, the present embodiment proposes a loose-leaf textbook construction and operation management system for vocational education, which comprises a textbook resource management module, a loose-leaf textbook generation module, a textbook operation monitoring module and a statistical analysis module. The textbook resource management module is used to build a resource library, manage and integrate various teaching resources, and provide an interactive channel for the participation of enterprise and school sides in editing, with resource processing function and text conversion function built in the interactive channel.

[0030] The loose-leaf textbook generation module takes the resource library as the basis, and is used to edit textbooks according to the needs of the school side, generate loose-leaf textbooks, and access relevant departments for textbook approval, and provide a textbook use channel for the school side after approval.

[0031] The textbook operation monitoring module is used to monitor the textbook operation process in real time, and provides a channel for students to feedback problems or suggestions, and informs the management enterprise side and the school side to handle them.

[0032] The statistical analysis module is used to periodically collect the use data of the textbooks for statistics and analysis, and generate a textbook evaluation report. The present application manages and integrates various teaching resources by building a resource library, and the construction and editing of the resource library can be jointly participated by enterprises and schools. Taking the resource library as the basis, the textbooks are edited according to the needs of the school side, and the loose-leaf textbooks are generated, and a channel is provided for students to feedback problems or suggestions, which is conducive to meeting the needs and feedback of users, intelligently generating corresponding textbooks, reducing manual management, improving efficiency, and adapting to the flexibility of vocational education.

[0033] The textbook resource management module, the loose-leaf textbook generation module, the textbook operation monitoring module and the statistical analysis module are based on the WIN system platform, developed by using AngularJS+NodeJS+NoSQL framework, the front-end interface is established by using AngularJS framework, and the service end is established by using NodeJS. The system provides a friendly user interface and a humanized operation process, so that the user can easily use the system.

[0034] The textbook resource management module includes an editing interaction module, a management integration module, and a resource library construction module. The editing interaction module includes an authentication module, an editing interaction channel, a resource processing module, and a text conversion module. The authentication module is used to verify the identity data of the enterprise and the school. After successful verification, the editing interaction channel is opened to receive data. The editing interaction channel is based on a server-side channel for transmitting XML, text, PDF, images, videos, and other file formats. It also integrates Big Data technology and uses distributed fast exchange technology for information transmission.

[0035] The resource processing module preprocesses the data received from the editing interaction channel. It uses Lightroom / ACR global noise reduction and Nik Dfine 2 local noise reduction to denoise the image data, and employs super-resolution algorithms, interpolation algorithms, and video coding algorithms to improve the resolution of the video data. Super-resolution algorithms convert low-resolution video frames into high-resolution ones using computer vision and image processing techniques. These algorithms typically use deep learning techniques, such as convolutional neural networks (CNNs), for training and optimization. Interpolation algorithms are mathematical methods to improve video resolution. They insert high-resolution pixel values ​​between low-resolution video frames to generate higher-resolution video frames. Common interpolation algorithms include bilinear interpolation, bicubic interpolation, and spline interpolation. Video coding algorithms compress video data into a smaller space, reducing the size of video files and improving transmission speed and storage efficiency. By using more efficient video coding algorithms, video resolution can be improved while maintaining video quality.

[0036] The text conversion module for image data employs a CNN to acquire visual features, an RNN to acquire sequence features of the image, and a classifier (CTC) or decoder (attention) to acquire text sequence information, thereby extracting the document from the image. Specifically, it uses a CNN to acquire visual features of the image; an RNN to acquire sequence features of the image; and a classifier (CTC) or decoder (attention) to acquire text sequence information. Secondly, regarding text recognition types, it can be based on characters or words. Character-based recognition has a smaller number of classifications but supports the recognition of custom words. Word-based recognition has higher accuracy. Character-based recognition is the primary method. The image text recognition algorithm is as follows:

[0037] CRNN algorithm:

[0038] Algorithm description: CNN + RNN + CTC

[0039] CNNs typically use VGG16, MobelNet, ResNet34, and ResNet50.

[0040] RNN: BLSMT / BGRU is generally used.

[0041] Classification loss function: CTC.

[0042] For video data, the Dynamic Time Warping (DTW) algorithm is used to identify documents in the video and attach the obtained documents to the corresponding data in the form of data packets. Dynamic Time Warping is a mainstream method in continuous speech recognition. While it involves significant computation, it is technically simple and boasts high accuracy. In systems with small vocabularys and isolated word recognition, many improved DTW algorithms have been proposed, such as methods using frequency-scale DTW for isolated word recognition.

[0043] The resource library construction module builds a resource library based on cloud storage to store the data received by the editing interaction module. The management and integration module uses the TF-IDF statistical document retrieval algorithm to evaluate the keywords in the documents. Based on different educational fields of vocational education, the documents in the resource library are classified according to the keywords. TF-IDF is used to extract and vectorize the features of the documents. pyLDAvis is used to perform visual clustering of the documents based on engineering project topics to obtain the visual clustering results. Then, the initial number of text documents k is selected according to the selection criteria of high intra-cluster similarity and low inter-cluster similarity of engineering project topics to obtain the initial model. Then, the correlation between different educational fields t is calculated. The TF-IDF formula is shown in formula (1):

[0044]

[0045] The distribution of feature terms across different categories within a single category and the positional factors of feature words affect the discriminative power of the text. The contribution of a word to discriminative power varies depending on its position within the text document. The TF-IDF method is used to calculate the weights of feature words, where word w is located in c... t The improved IDF calculation formula in the class is shown in formula (2):

[0046]

[0047] In formulas (1) and (2), N is the total number of text documents, T is the total number of terms, and x is the number of text documents containing term t, while c t The number of text documents is y, excluding c.t The number of text documents containing term t is k;

[0048] The correlation calculation for different educational fields is shown in formula (3):

[0049] relevance(term_w|topic_t)=λ*p(w|t)+(1-λ)*p(w|t) / p(w) (3)

[0050] In formula (3), the relevance of a word to the education field topic is adjusted by the λ parameter. If λ is close to 1, then the word w that appears more frequently under the project topic t is more relevant to the project topic t. If λ is closer to 0, then the more special and unique word w under the project topic t is more relevant to the project topic t. By adjusting the size of λ, the relevance of the domain word term_w to the project topic topic_t can be changed. After selecting a project topic, the words closest to the project topic are selected. By summarizing the meaning expressed by these words, the meaning of the project topic can be summarized, thereby assessing the importance of a word to the education field in the document and extracting keywords.

[0051] The loose-leaf textbook generation module includes a textbook editing module, a textbook generation module, a textbook approval module, and a textbook usage module. The textbook editing module receives the school's requirements, uses the STAR-Net algorithm to infer the semantics of the requirements, and combines it with Term-Frequency, Inverse Document Frequency, and TF-IDF algorithms to extract text, as well as corresponding image and video data from the resource library that are suitable for the school's requirements.

[0052] STAR-Net: Spatial Transformer + CRNN.

[0053] Term-Frequency: The number of times a word appears in a document within a given corpus, divided by the total number of occurrences in that document.

[0054] Inverse document frequency (IVF) is a measure of the general importance of a word. The more common a word is, the larger the denominator, and the smaller the inverse document frequency, which is closer to 0. Adding 1 to the denominator prevents the denominator from being 0.

[0055] TF-IDF: Final TF-IDF = Term Frequency (TF) * Inverse Document Frequency (IDF).

[0056] The above formula shows that TF-IDF is directly proportional to the number of times a word appears in a file in the resource library, and inversely proportional to the number of files in the resource library that contain that word. TF-IDF can be used as an algorithm to extract keywords from a file, that is, to calculate the TF-IDF value of each word in the document, and then sort them in descending order. The first few words can be regarded as important terms in a document.

[0057] The textbook generation module extracts data from the textbook editing module and generates a loose-leaf textbook with layout, content arrangement, interactive elements, and functional notes that meet the school's requirements. Specifically: Layout design: Ensuring aesthetics and readability, including clear and concise titles and subtitles, segmented layout, appropriate white space, suitable fonts and font sizes, concise and clear images, charts, and tables, and proper attribution and copyright information; Content design: Determining the structure, organization, and presentation of the textbook content, including chapter order, themes, concepts, examples, and cases; designing the textbook style, including fonts, layout, colors, icons, and cover; writing the textbook content, including text, images, charts, and examples; reviewing the textbook to ensure accuracy, completeness, and ease of understanding; and printing and binding; Interactive design: Adding interactive elements, such as question-and-answer sections, exercises, case studies, and practical activities, to enhance learner engagement and learning effectiveness; and analysis of professional job positions and typical work tasks. By analyzing professional job positions and typical work tasks, theoretical knowledge is combined with enterprise work tasks, integrating content on professional ethics and moral education; the textbook is modularly designed. The loose-leaf textbook contains three parts: modules, projects, and tasks. Loose-leaf notes are used for learning records and supplementary content, practical training is combined with specific tasks, and functional inserts provide additional information and resources; horizontal and vertical modules are divided into six parts: information, planning, decision-making, implementation, inspection, and evaluation, and three stages: preview, implementation, inspection, and evaluation.

[0058] The textbook approval module connects the school's review department and relevant regulatory departments online. It allows schools to submit generated loose-leaf textbooks. Once approved, the textbook usage module is opened. This module is deployed using the ElasticSearch+Logstash+Kibana framework, forming a Kibana visualization platform for direct online use by schools. Simultaneously, it provides printing permissions for printed textbooks, facilitating both use and direct printing.

[0059] The design and development of loose-leaf teaching materials includes loose-leaf textbooks, loose-leaf notes, teaching resource packages, and other teaching materials. Loose-leaf textbooks are a crucial component, playing a coordinating and guiding role. "Loose-leaf textbooks" possess the dual attributes of "loose-leaf" and "textbook." "Loose-leaf" features structure, formalization, modularity, flexibility, reconfigurability, and engaging elements, aligning with teaching, self-directed learning, and personalized learning. Specifically, it includes: "School-Enterprise Dual System and Cooperation," based on real-world enterprise scenarios, showcasing new industry formats, levels, and technologies to cultivate students' comprehensive professional qualities; "Digital Resources," supporting teaching development of micro-lecture videos, animations, and other digital resources to help students understand key points and difficulties in the textbook; and "Curriculum Ideological and Political Education." The textbook incorporates the spirit of craftsmanship, providing students with a rich intellectual experience; it employs a "task-based writing method," based on national occupational standards, aiming to cultivate comprehensive vocational abilities, using typical work tasks as a vehicle, centering on students, and prioritizing ability development, combining theoretical and practical learning; it uses "loose-leaf binding," bound by textbook publishers; and it features "dynamic updates and management," requiring timely adjustments to the content of loose-leaf textbooks as technology advances, job requirements change, student learning evolves, and training objectives are adjusted. Therefore, a mechanism for updating and adjusting loose-leaf textbooks is established. Vocational education loose-leaf textbooks are not only used in school teaching but also in corporate training and self-study by working professionals.

The management and integration module uses the TF-IDF statistical document retrieval algorithm to evaluate the keywords in the documents and classifies the documents in the resource library according to the keywords based on different educational fields of vocational education.

6. A construction and operation management system for loose-leaf textbooks for vocational education according to claim 5, characterized in that: The loose-leaf textbook generation module includes a textbook editing module, a textbook generation module, a textbook approval module, and a textbook usage module. The textbook editing module receives the school's requirements and uses the STAR-Net algorithm to infer the semantics of the requirements. It combines this with Term-Frequency, Inverse Document Frequency, and TF-IDF algorithms to extract text, images, and video data from the resource library that are suitable for the school's requirements. The textbook generation module then uses the data extracted by the textbook editing module to generate a loose-leaf textbook with a layout, content arrangement, interactive elements, and functional notes that meet the school's requirements.

7. A construction and operation management system for loose-leaf textbooks for vocational education according to claim 6, characterized in that: The textbook approval module is used to connect the school's review department and relevant regulatory departments online, submit the generated loose-leaf textbooks, and after the review is approved, open the textbook usage module. The textbook usage module is deployed using the ElasticSearch+Logstash+Kibana framework to form a Kibana visualization platform for schools to use directly online, and simultaneously provides printing rights for paper textbooks.

8. A construction and operation management system for loose-leaf textbooks for vocational education according to claim 1, characterized in that: The textbook operation monitoring module includes a supervision module and a feedback module. The supervision module is used to monitor the operation process of the textbook in real time, including judging whether the publication and use process of the textbook is compliant, judging whether there are typos in the textbook, and notifying the management company and the school using the textbook when problems are found.

9. A construction and operation management system for loose-leaf textbooks for vocational education according to claim 8, characterized in that: The feedback module is an open channel and provides a student feedback channel for anonymously collecting student feedback on questions or suggestions, and then feeding back the questions and suggestions to the school and the company. Different questions or suggestions are sorted by the frequency of their submission.

10. A construction and operation management system for loose-leaf textbooks for vocational education according to claim 9, characterized in that: The statistical analysis module is used to periodically collect and analyze textbook usage data, including textbook usage rate, vocational education pass rate of students using this textbook, and school ratings of the textbook, thereby generating a textbook evaluation report to provide data support for teaching evaluation and improvement.
