4C/ID model in practice

This week my students were working their first individual project, creating a website from sketch. At first, since we have been going through this process for about five times, I planned to demonstrate the whole process again at the beginning of the class. Then let them do it by themselves. And then I realized that I underestimated the complication of this task. They had some difficulties when doing it independently. Although my students went through all the steps for several times, they did it by following my demonstration, and they have never gone through the whole process in one time. So there is a gap. According to van Merriënboer's 4C/ID model, the scaffolding should be removed corresponding to students' progress. Apparently, I removed the scaffolding to fast. So I created a job-aid to help them through this process and tried to use it in another section I taught. This time students' reaction was very positive, which indicated that this intervention really helped.
