為了解國中生的家庭社經地位、文化資本、自然科學習興趣對自然科學習動機成長情形之影響，本研究使用「國民中學學習狀況之追蹤調查資料庫」，以臺北市文山區2403名國中生為母群，有效樣本為709位，透過潛在成長曲線進行分析，研究結果包括：一、國中生自然科學習動機隨著年級提高逐年下降；二、國一生的家庭社經地位對自然科學習動機沒有明顯影響；三、國一生的家庭社經地位對後續五學期的自然科學習動機有正向影響；四、國一生的家庭文化資本對自然科學習動機有正向影響；五、國一生的家庭文化資本對後續學期的自然科學習動機有正向影響；六、國一生的自然科學習興趣對自然科學習動機有正向影響，國一生的自然科學習興趣對後續學期的自然科學習動機有正向影響。
