本研究主要探討以十週棒球運動文學課程，對於自我認知強烈的國中生，在運動態度及內在動機上的影響。本研究以準實驗研究法，以桃園市某公立國中三年級學生為研究對象。實驗組29人，於學期中以十週聯課時間教授棒球文學；控制組28人，教學維持不變。首先於實驗教學前實驗組、控制組分別施以前測，經過實驗組實驗教學後，再分別施以後測。在資料分析方面，所採統計方法包括描述性統計、迴歸同質性考驗、單因子共變數分析、獨立樣本t考驗、詹森－內曼統計法檢驗變項間的關係。本研究所得結果如下：一、實驗組、控制組於實驗前在棒球上的運動態度、運動動機，男生平均數皆比女生高，顯見男生對棒球普遍較女生有較高的興趣。二、實驗組於實驗教學後，整體棒球運動態度未達顯著差異，男生運動態度平均數小幅退步，女生運動態度平均數則小幅進步。三、實驗組於實驗教學後，整體棒球運動動機達顯著差異，而其達顯著差異中，男、女生效果剛好相反，男生平均數降低，女生平均數則提高。本研究針對以上結果加以討論，得知以棒球運動文學介入平日教學，男生在運動態度及運動動機上沒有效果，女生則在運動動機上有顯著的效果，建議學校在體育相關教學中，對於運動動機及運動態度上，可多做跨領域的合作，並考慮性別的不同而有不同的教學方法。

In this study, we tried to identify the effects on sport attitude and inner motivation of Junior High School Students after 10-weeks Baseball Literature. The study took students of 9th grade of a public junior high school in Taoyuan City. Experimental Group consisted of 29 persons and Control Group consisted of 28 persons. Control Group maintained normal curriculum and the Experimental Group was given with the lecture of 10 weeks Baseball Literature in Extra Curriculum Class. Both groups were tested before and after the experiment. In data analysis, we adopted a number of statistical methods, including Descriptive Statistics, Homogeneity of Regression, One-Way ANCOVA, Independent-Sample T-test, Johnson-Neyman Techniques to test the relationship between various variables. The outcomes of the Study are given below: 1. Before the experiment, boys of both Experimental and Control Groups are higher than girls in average in both Sports Attitude and Sports Motivation. It is obvious boys have higher interests in baseball than girls, generally. 2. After the experiment, sports attitudes of both Experimental and Control Group are not tested to be varied significantly; however, both groups are shown varied significantly in baseball sports motivation. 3. In the sports attitude progress of Experimental Group is not varied significantly in both boys and girls; on the other hand, in progress of sports motivation, both boys and girls varied significantly. After discussion of the outcomes as stated above, introduction baseball sports literature into ordinary curriculum is not effective in both sports attitude and sports motivation of boys, but girls are showing significant effects in the part of sports motivation. It is therefore suggested that in the physical education related instructions, give higher emphasis in cross-field cooperation and adopt different instruction approach basis gender difference.
