本研究結合家長參與兒童家中電腦網路學習的相關因素，應用「計畫行為理論」建構一個整體性的「家長參與兒童家中電腦網路學習行為意圖模式」，透過實證研究的方式，加以驗證此理論模式的適用性。本研究採用問卷調查法，針對661位國小學童家長進行施測，並採用SPSS與LISREL套裝軟體，建立資料檔案並進行各項統計分析。研究結果發現：一、家長參與行為意向的理論模式與實證資料適配程度良好。二、家長參與之行為意圖對家長實際參與行為有顯著直接效果。三、家長參與兒童家中電腦網路學習的行為態度、主觀規範及知覺行為控制對其參與的行為意圖有顯著直接效果。最後，本研究根據研究發現提出三項針對教育實務與研究之建議。

This study applied the theory of planned behavior (TPB) to explain the behavior intention of elementary school students’ parents’ involvement in children’s computer and Internet use for learning at home and to investigate the key impact factors on their attitude, subjective regulation, perceived behavioral control and behavior intention. The subjects were six hundred and sixty-one elementary school students’ parents who were asked to response to the questionnaire, and SPSS and LISREL were used to analyze the data. The research conclusions were as follows: (1) The theoretical model of parents’ involvement behavior intention in children’s computer and Internet use for learning at home fit the observed data quite well. (2) “Behavior intention” had significant direct effects on “actual behavior”. (3) “Attitude”, “subjective regulation” and “perceived behavioral control” had significant direct effects on “behavior intention”. Finally, suggestions for educational practices and further research are proposed.
