An Interactive Geometric Drawing System Based on Web

Abstract

The invention provides an interactive type geometric construction system based on the Web. The interactive type geometric construction system is mounted on a Web server and a database server, so that a client terminal and a teacher end can perform online interactive study through the Internet. The interactive type geometric construction system based on the Web comprises an input unit used for obtaining the task and the requirement for geometric construction and recording a construction operation process, a drawing unit used for calling a corresponding geometric model to carry out geometric construction on a web page according to the task and the requirement for geometric construction, a diagram detecting unit and an output unit. The diagram detecting unit is used for detecting whether a diagram is correct or not. The output unit is used of obtaining a checking result, outputting a final result diagram and recording the geometric construction process. By means of the interactive type geometric construction system based on the Web, the stability of the system is good, the system is easy to operate and the online learning efficiency is improved as the interactive type geometric construction system based on the Web is provided with the intelligent prompt and judgment and process monitoring.

Description

technical field [0001] The invention relates to a geometric drawing system, in particular to a Web-based interactive geometric drawing system. Background technique [0002] In recent years, with the popularization and promotion of broadband Internet and mobile Internet technology, online learning has become an important way of learning, not only for adults, but also for primary and middle school students' in-class learning and extracurricular tutoring. [0003] In the teaching process, how to use the characteristics of timely computer feedback and what you see is what you get to develop students' mathematical ability has been paid more and more attention. The geometric drawing ability is the foundation and difficulty of mathematics learning in primary and secondary schools. [0004] Many schools are using stand-alone software such as Geometric Sketchpad to assist teachers in formulating questions, drawing pictures and making animation demonstrations during lesson preparatio...

AI Technical Summary

Problems solved by technology

[0004] Many schools are using stand-alone software such as Geometric Sketchpad to assist teachers in formulating questions, drawing pictures and making animation demonstrations during lesson preparation, so as to help students more easily form graphics and spatial imagination, but because: 1) need to install fixed software, Moreover, there is a problem of compatibility between the software version and the operating system. For many years, students have not been able to benefit from this kind of computer drawing operation, especially with the popularity of tablet computers and large-screen smart phones, how to use computers more conveniently when cross-platform Drawing becomes a problem; 2) The stand-alone version of geometric drawing software cannot provide intelligent judgment of correctness and error of drawing, so it cannot meet the needs of students' independent online learning; 3) When students have problems in the process of drawing, they need to consult the teacher At the same time, the existing drawing software cannot reproduce the students' drawing process, so the teacher cannot effectively observe the students' thinking process, and cannot effectively provide targeted guidance
