This　research　investigated　the　application　of　linear　structural　equation　model　in　analyzing　the　influencing　factors　on　learning　interest　in　the　course.　Algorithms　and　Data　Structures　in　computer　science.　Our　results　show　that　the　main　factors　impacted　on　learning　interest　of　the　students　are　students　specialized　basis　and　teachers　teaching　strategies.　The　weights　of　effects　on　learning　interests　for　the　two　factors　are　49.56%　and　43.11%,　respectively.　Good　teaching　effects　and　teaching　strategies　are　important　to　arouse　the　students　learning　interest.　©　2011　IEEE.
