The class quasi-experiment was conducted to determine whether using computer simulation teaching strategy enhanced student understanding of statistics concepts for students enrolled in an introductory course. One hundred and ninety-three sophomores in hospitality management department were invited as participants in this two-year longitudinal study. Students received computer simulation intervention in experimental group and traditional teaching method in control group. In particular, learning effectiveness difference was found in two groups. The pretest scores were found to do something with the improvement rate. The preliminary results of this study indicated some evidence that these methods may improve student understanding of statistics concepts.
