High School Information Technology Courses Online Review System Design

Before the professional level test of information technology, teachers and students always review systematically. However, every student varies in their basis, knowledge mastered and knowledge unknown to them, while the present information technology test system or stimulation practice system handles every student in the same way with the same testing content or the same practicing content. It results in, to some extent, wasting their study time (spend their time in vain on practicing what they have already known time and time again). Meanwhile, students can not practice fully what they have not mastered, which downplay the class efficiency in revision lessons of information technology.The design of An Online Revision System of Information Technology in High Schools is an online revision system of information technology specifically developed on basis of sufficient analysis of characteristics of information technology in high schools (There are many students in a class and the teacher is unlikely to take every student's needs into account.) and peculiarities of high school students (with various base and demand for themselves).It has the following functions different from other systems.1. Enforcement of the error correctionWith the different academic requirements of students, the quality of their practice is different. Some students hold negative attitude to the tasks assigned by teachers. The correct rate of each practice is very low. In response to such a situation, the online review system will automatically record the mistakes made by the students to set up their own mistake bank. Correcting mistakes becomes part of the mission. If it can not be completed, they can not go to the next module to study. So it guides students to take every practice seriously, and at the same time facilitates students to grasp these mistakes.2. Personalized review functionThe contents mastered by students vary. If teachers do a unified review, the students will certainly waste part of their time. The online review is to allow students to review what is still new to students and do consolidation exercise accordingly. This avoids wasting time and improves classroom efficiency.3. Intelligent guidance functionTeaching in large classes can not be concerned about all students, leaving some problems unsolved, thus affecting this part of the follow-up training of students and wasting their valuable study time. In response to this circumstances, the online review system will automatically adjust to student mistakes and pick out points of knowledge for students. Through a series of knowledge and the consolidation exercise, students can master the content.This paper introduces the design of the "high school information technology course online review system ", and realize some of the key technologies and skills.
