It is also an effective mode.Digital Graphic Design is a foundation course with strong practicality and applicability for undergraduates majoring in educational technology, which is mainly using Photoshop, or CS2 to illustrate the basic function of computer image processing and editing. The network teaching platform for undergraduates of IMNU is an'all-in-one and digitizing teaching supporting environment' based on the existing CRTVU, which can provide teachers teaching activity supporting constructivism teaching designing theory. This paper combines the teaching function of network teaching platform and is guided by modern theory of learning.

Students are guided and boosted to understand the interconversion of Photoshop's and CS2's precinct and path and the integrated application of layer and path. From students'information literacy and cooperation ability, the results of learning activities are analyzed. After that, teaching self-examination is necessary which will be the reference for the next teaching activity. |
