Research Of Automatically Appraise Strategy Based On VB Program Design

With the continuous development of information society, information technology education is more and more popular in middle school education, the middle school information technology curriculum has been incorporated into the scope of the college entrance examination. Middle school information technology curriculum includes compulsory module "information technology" and elective module "algorithm and program design","the application of multimedia technology"."Algorithm and program design" as an elective module, mainly in the VB program design as an example to introduces the algorithm and the algorithm for programming languages. From the college entrance examination in recent years can be seen, more and more students choose to answer the test of this module.In this study, through the analysis of the information technology curriculum in middle school, used a relatively perfect evaluation strategy, construction of automatic marking system based on VB program design, it is according to the students’ progress and mastery level formation test, after automatic marking, error analysis of questions and related knowledge involved, and give feedback to the students and teachers. Students through the feedback of evaluation results and error analysis of the knowledge points, can be more comprehensive understanding of their learning situation, better combination of classroom learning. Teachers can report the overall level of error distribution, according to the evaluation results of statistical analysis of the data, effectively improve the teaching content and teaching strategies.This article based on the VB programming framework for an automatic marking system of VB program, access to VB program information by way of words recognition, parsing and code analysis, and then according to the acquired information, automatic marking of the program. The focus of this study is to analysis and implementation of automatic marking strategy of VB program design. The innovation of this research is to execute the VB script language using the "Script Control" control, propose the VB code to test components design scheme, improve the generality of automatic marking system. Another innovation is proposed for data analysis on the idea of automatic evaluation results, the error of knowledge distribution feedback to students and teachers, it can improve the quality of teaching.This paper works as the following:Firstly, this article discussed and introduces the course "algorithm and program design" teaching and evaluation methods in detail, listed knowledge framework and content of the course, laid a solid theoretical foundation and practical foundation for later research.Secondly, this article analyzed the acquisition method on the VB program information, made a good preparation for the research of automatic marking strategy on VB program design, Is conducive to achieve the automatic marking system.Thirdly, this article describes the process and implementation of automatic marking strategy on VB program design in detail, according to several VB programming regular examination questions corresponding reading strategies are presented, and combined a specific case to make the detailed description of automatic marking strategy on VB program design.Finally, this article based on the automatic marking analysis the results, create table of generate error distribution and result analysis report and then give the feedback to teachers and students,, and the independent study and analysis of the contents of these two parts are integrated into the learning platform.
