• 中文摘要： 本研究共設計了兩套作為診斷學生投影概念的示範實驗群測工具。這些工具的設計參考了皮亞傑原始的個別面診過程。診斷對象約四百位學生，其中包括國中、高中及大學理科和非理科的學生。 本研究不祗是重新確認了前人研究報告所宣稱關於學生的若干自發性投影概念，同時也發現了許多新的概念特性。 根據皮亞傑關於思想的操作觀點，我們對這些投影概念的特性和發展，作了探一層的探討和統計分析。研究結果發現這些概念可以區分為三個發展階層。 我們也分析了學生的投影概念階層和代表一般認知成長的重量和體積概念的關係。它們之問有顯著的相關性。 本研究並且嚐試探討了這些發現在教學上的意義。
• 英文摘要： In this study，diagnostic group tests for investigating students' conceptions of shadow forma-tion were designed based on Piaget's original clinical procedures．More than four hundred students，including high school students，non-science and science major college students，were tested usingthese instruments． Various misconceptions as pointed out by previous investigators were confirmed and new featureswere also discovered among our subjects．The insight， meaning and developments of these concep-tions were studied statistically and analysed from a Piagetian view of operational thinking. Threedevelopmental levels of these conceptions were found． The correlations of these conceptual levels and the general cognitive developmental stages，asindicated by the abilities in weight and volume concepts，were also statistically investigated．Thelevels of shadow formation were found to be highly dependent on these cognitive stages. The meaning of these findings to teaching and learning were also discussed．
