Evaluating the web-based instruction by item analysis

The web-based instruction has been rapidly increasing in the educational environment with the development of information and communication technology, and this has brought a need for evaluating the web-based instruction. This paper evaluates the web-based instruction by investigating the levels of students satisfaction and comparing them with the lecture-based instruction to find the differences between the two instructions and the problems of the web-based instruction. The results reveal that the web-based instruction has the advantage of multimedia effects but needs to be more improved in terms of interactions. Also, the factor analysis shows that the web-based instruction is composed of two dimensions of presenting instructional materials and operating a course while the lecture-based instruction is composed of only one component. These findings suggest that the web-based instruction should be designed and implemented in consideration of the features of the web system.
