Electronic book system based on dynamic geometry and computer algebraic system

Abstract

The invention discloses an electronic book system based on dynamic geometry and computer algebraic system. The electronic book system comprises a text module, a dynamic geometrical graphic module, a computer algebraic system, an interactive widget module and a typesetting module, wherein the typesetting module is respectively in electric connection with the text module, the dynamic geometrical graphic module, the computer algebraic system and the interactive widget module; the interactive widget module is respectively in electric connection with the text module, the dynamic geometrical graphic module and the computer algebraic system; and the computer algebraic system is respectively in electric connection with the text module and the dynamic geometrical graphic module. According to the invention, a dynamic interactive book with continuous front and back contents, parameters and action driving can be prepared by inserting the dynamic text, formula, geometric object with constrained relationship and widget (button, input frame, slide rod, and the like) for controlling the parameter conversion and combining with the paging and typesetting of the file. After the book is prepared, the user can read, operate and share on a browser in a cross-platform manner, without using any plug-in and player.

Description

technical field [0001] The invention relates to the technical field of electronic teaching materials and teaching aids, in particular to an electronic book system based on dynamic geometry and computer algebra systems. Background technique [0002] Most of the existing e-book generation methods use the following methods: digitization of paper books, and direct digitization of existing paper books through image scanning; making e-books through general document editing software, in the text content Insert static pictures, graphics, etc., and finally generate documents in pdf or other formats; use flash and other animation software combined with certain programming to create dynamic books with specific content; dynamic geometry and computer algebra systems are widely used in various teaching aids , such as the familiar Super Sketchpad, Geometry Sketchpad, etc., can be used to create dynamic and interactive courseware content related to mathematics, physics and other subjects. ...

Problems solved by technology

[0003] The digitization of paper books is a fast way to generate e-books, but the generated content is limited by existing publications, and the content is rigid. Since most of them are generated by image scanning technology, the files take up a lot of space; e-books made by general-purpose document editing software , the content can be customized, and rich pictures and graphics can be inserted, the generated file is small in size, and the layout is reasonable and easy to read, but it cannot support dynamic geometry and algebraic operations, and cannot meet the needs of interactive science and engineering content; through flash The dynamic books with specific content produced by animation software combined with a certain program design can add some dynamic content and meet some interactive needs, but the production process is complicated and requires the cooperation of content experts, technical experts and other experts in various fields. Completed; Super Sketchpad and Geometry Sketchpad are teaching aid software familiar to mathematics teachers. Using these software, dynamic and interactive courseware can be produced to visualize abstract mathematical problems, but these software lack complete word processing and typesetting, it is impossible to generate multi-page e-books, and the generated content can only be opened with specific software, which greatly limits the use of users
