Abstract

The purposes of this research are to construct and validate the efficiency of the computer-assisted instruction in IEG320 Probability and Statistics for Engineer. The instrument used in the research comprise of unit test, satisfied evaluated questionnaire, and computerassisted instruction including pre-test, post-test. 20 students, enrolled in IEG 320 Probability and Statistics for Engineer in 2nd semester of 2011 academic year, sampled by using purpose are applied to this research. The students took pre-test, unit test, and post-test. The scores from these Probability and Statistics for Engineer test are proposed. The efficiency of the computer-assisted instruction is 80.50/81.50 which more than standard criteria 80/80. Moreover, the averaged difference from pre-test and post-test score is significantly statistics at level .05.
