Research And Implementation On Data Acquisition System Of Learning Evaluation For Web-based Education

Web-based learning evaluation is used to change the behavior of the student for web-based Learning, and provide an important help to improve learning. An effectively actualized evaluation can't go without sufficient and objective data, so whether can we collect learning evaluation data or not has direct relationship with the result of learning evaluation.On one side, teachers and students are separated, and learning activity is unstable, which brings even more problems to collect evaluation data to web-based learning than to traditional education. On the other side, the acquisition system of web-based evaluation and the education theory are not deeply united, so information collected by the acquisition systems are not enough to support the efficient evaluation, and because the method of interaction is not reasonable , some system can not gather enough evaluation data.With analysis and research on principles of collecting evidences and technologies of designing system, this paper designed a standard for classifying evaluation data, and Implemented data acquisition system of learning evaluation for web-based education. The main work of this paper includes:Firstly, classified the learning evaluation data for web-based learning into three sorts: collecting web quiz data, collecting web test data and collecting self's and each other's evaluation data.Secondly, constructed hanging web quiz module to collect web quiz data in order to enhance the probability of students' attendance, and solved the problem of data's lack in web quiz.Thirdly, constructed the method for collecting data from formative test, with test paper's creation, examination and score's made automatically in order to collect more test data.Fourthly, through self's and each other's evaluation, and teacher's evaluation on rewards and punishment, writing diary and sending exercises to collect self's and each other's evaluation data.Fifthly, this paper constructed the module which could display every kind of evaluation data and could support data analysis.
