This study explores the effectiveness of two different formative examination strategies on the University of Technology students' achievement on their learning achievement in an e-Learning environment of Calculus course. Quasi-Experimental design is employed; 167 students from three classes of one University of Technology in the study. These students' classes are randomly assigned into two groups, Group ”A” and Group ”B”, to learn the topic ”Differentiation and Integration”. Two classes test in the computer classroom(Group ”A”), and one class tests in the traditional classroom Group ”B”). However, there is significant difference between Group ”A” and Group ”B” in the Differentiation achievement. But next semester, we hold traditional tests in three traditional classrooms. There is significant difference between Group ”A” and Group ”B” in the Integration achievement.
