Abstract：The purpose of this study was to examine the effects of a computer simulation program for teaching health-related physical fitness on physical education teacher education (PETE) students' creativity and pedagogical content knowledge. Eighty-six PETE students participated in this program. Forty-four students were assigned into a computer simulation program for teaching health-related physical fitness class as an experimental group. Forty-two students were assigned to a direct teaching class as a control group. Sixteen weeks of a computer simulation program for teaching health-related physical fitness was implemented. All participants completed the new test of creativity assessment and scale of pedagogical content knowledge before and after the intervention. The results indicated significant group × time interactions on creative thinking ability and pedagogical content knowledge, and the experimental group participants' creative thinking ability performed significantly better scores than the control on the variables. However, there was no significant difference between 2 groups. Also, the participants in the experimental group achieved significantly higher scores on the post-test of creativity and pedagogical content knowledge than n the pre-test, while the participants in the control group only demonstrated significantly better scores on the post-test of verbal flexibility of creativity than the pre-test. We conclude that the computer simulation in teaching health-related physical fitness program could enhance creative thinking ability and pedagogical content knowledge in physical education. Therefore, this program may be employed on the spot teaching, when they encounter difficulties, allowing learners to pre-design creativity, then execute, identify, evaluate and develop different learning experiences in teaching health-related fitness program.
