Experiences in automatic assessment on mass courses and issues for designing virtual courses

Abstract

In this paper, we present some experiences on using automatic assessment in large scale courses of introductory programming, data structures, and algorithms over a period of 10 years. Automatic assessment provides an effective method for giving immediate 24/7 feedback service for students of mass courses. A very important factor in the promoting of learning is the possibility to resubmit answers after receiving the feedback. However, our experience shows that the resubmission option is not the only key motivation factor. More important factors include the challenge of exercises and the grading scale or the course assignments. A successful combination of all of these can produce good learning results.
