Abstract Title: Validation of the Japanese translation of the Force Concept Inventory and preliminary data analysis on the effects of class instruction and gender
Abstract: The Japanese translation of the Force Concept Inventory (FCI) was evaluated using the classical test theory indices for its quality as a concept inventory. Based on a hypothesis that Japanese students and American students share similar concepts of motion and force, the item difficulty indices of the pretests of American students and Japanese students attending mid-level universities in their respective countries were compared. The indices indicated that the Japanese translation is of high quality and comparable to the original FCI (correlation coefficient between the two groups = 0.87). Because the results indicated that the Japanese translation of the FCI is of high quality, the Japanese data on the pretest and posttest scores were then analyzed to measure the efficacy of class instruction. The data analysis showed that the posttest scores of Japanese students depended primarily on their pretest scores and secondarily on class instruction but not on gender.
