以潛在成長模式探索國中生家庭學習資源與英語學習動機變化對英語學習成就的影響

Using the Latent Growth Modeling to Explore the Impact of Changes in Family Learning Resources and English Learning Motivation of Junior High School Students on English Learning Achievement

本研究以基隆市國中生學習狀況資料庫的3,309名學生資料，探討五學期的家庭學習資源與英語學習動機成長軌跡，並分析家庭學習資源與英語學習動機成長對英語學習成就的影響。潛在成長模式分析顯示：國中生家庭學習資源成長軌跡呈直線平穩趨勢，學生在八年級下學期最高，隨著學期往後推移逐漸減少，最低點為九年級上學期。國中生英語學習動機成長軌跡呈直線下滑趨勢，七年級下學期最高，九年級上下學期最低。七年級生的家庭學習資源與英語學習動機愈好，九年級英語學習成就愈好；同時在五學期家庭學習資源與英語學習動機成長對於九年級英語學習成就提升效果。學校及教師應針對家庭學習不利子女提供英語學習扶助方案，並應提出改善提升各學期英語學習動機的策略。

The purpose of this study is to use the data of 3,309 students in the learning status database of junior high school students in Keelung City to explore the growth trajectories of family learning resources and English learning motivation during the five semesters, and analyze the impact of family learning resources and the growth of English learning motivation on English learning achievement. Analysis of the latent growth modeling showed that the growth trajectory of family learning resources for junior high school students showed a linear and stable trend. The growth trajec-tory of students was the highest in the second semester of eighth grade, and gradually decreases as the semester went by. The lowest point is in the first semester of ninth grade. The growth trajectory of English learn-ing motivation of junior high school students showed a linear downward trend, with the highest level in the second semester of seventh grade and the lowest in the first and second semester of ninth grade. The better the home learning resources and English learning motivation of seventh-grade students, the better the English learning achievements of ninth graders; at the same time, the growth of home learning resources and English learning motivation in the fifth semester had an effect on im-proving the English learning achievements of ninth graders. Schools and teachers should provide English learning support programs for children whose families were disadvantaged in learning, and should propose strat-egies to improve English learning motivation in each semester.
