The main purpose of this research is to investigate the difference in the accuracy of the forehand long-stroke performed by the badminton players in different groups of "Goal of Motor Learning" and "Achievement Motivation" in the beginning stage. This data is intended to be a reference to improve the P. E. (Physical Education) teaching. First of all, this research administered the test of "Goal of Motor Learning Scale" and "Achievement Motivation Scale", then, proceeded the practical teaching and testing of the forehand long-stroke of badminton. All the data were collected through the Two-Way Anova, and conclusions were made as following: 1. According to the analysis of "Goal of Health, the first factor of Goal of Motor Learning" with the four factors of "Achievement Motivation", we find that there are no interactions with each other between factors. But, the data indicate: (1) In the analysis of the learning performance in different groups of "Goal of Health" and "Work Mastery", we conclude that in the accuracy of the forehand long-stroke in the beginning stage, the testees in high "Work Mastery" have higher performance than the testees in low "Work Mastery". (2) In the analysis of the learning performance in different groups of "Goal of Health" and "Work Orientation", we conclude that in the accuracy of the forehand long stroke in the beginning stage, the testees in high "Goal of Health" have higher performance than the testees in low "Goal of Health". (3) In the analysis of the learning performance in different groups of "Goal of Health" and "Personal Unconcern", we conclude that in the accuracy of the forehand long-stroke in the beginning stage, the testees in high "Goal of Health" have higher performance than the testees in low "Goal of Health". 2. According to the analysis of "goal of Achievement, the third factor of Goal of Motor Learning" with the four factors of "Achievement Motivation", we find: (1) "Goal of Achievement" and "Competitiveness" interact with each other: in the accuracy of the forehand long-stroke in the beginning stage, the testees in low "Goal of Achievement" but high "Competitiveness" and high "Goal of Achievement" but low "Competitiveness" have higher performance than the testees in low "Goal of Achievement" but low "Competitiveness". (2) In the analysis of the learning performance in different groups of "Goal of Achievement" and "Work Mastery", we conclude that in the accuracy of the forehand long-stroke in the beginning stage, the testees in high "Work Mastery" have higher performance thant the testees in low "Work Mastery".
