Description

Rich media editing method, generation method, device and system in intelligent teaching materials

Technical field

The present invention relates to the technical field of information data processing, and in particular to rich media editing methods, generation methods, devices and systems in intelligent teaching materials.

Background technique

Intelligent electronic textbooks or learning resources are different from ordinary e-books. Instead of simply scanning traditional textbooks and placing them on the learning network, intelligent electronic textbooks or learning resources condense the depth of teaching content and knowledge points by front-line teachers. The concept of mining, processing and planning, combined with integrated media arrangement design, displays text, pictures, audio, video and other contents in one scene, and can achieve good interaction with learners, allowing students to learn, practice and test in one place Completed in the scene, it truly realizes the digitization of teaching material content and the intelligence of interactive functions.

However, the current process for producing such an intelligent electronic textbook or learning resource is very complicated. It is roughly as follows: First, teachers involved in the planning need to document the content of the textbook and the form in which it is presented. For example, the recording method is Word software, as shown in Figure 1. The specific method is to write the teaching material content in Word, and then use the annotation function to mark out the form in which the content will be presented. Then the art editor will design according to the document content, and finally the production will be done. The teacher writes the content of the teaching material into an HTML file through programming based on the annotations in the Word document and the design of the art editor.

The above process is very complicated, especially the editing of rich media, such as inserting clickable pictures, inserting galleries, videos or audios, etc. The planning teacher first needs to describe the specific implementation effect in the form of comments and upload the rich text file to be edited. It also requires the art editor to design based on the document content. Finally, the production teacher needs to write the corresponding HTML file based on the annotations in the Word document and the art editor's design to achieve rich media editing. It requires a lot of time and energy, which greatly reduces the efficiency of teachers in planning and editing a teaching material, and also greatly weakens the enthusiasm of teachers to participate in planning and editing teaching materials.
