近年來，在自然與生活科技領域的學習上，學習者的需求逐漸從技能學習轉變為合作式的問題解決，而合作式問題解決也成為現今學習者必備的能力之一。因此本研究旨在探究合作式問題解決教學法，並將此教學法應用於國民小學動力機械課程的設計與將此教學法落實於教學活動執行之中。此外，本研究更確實地開發出一套完整的小學動力機械課程的教材，教材單元分別是國小課程當中的力與結構及齒輪與滑輪兩個單元，各個單元包含課本、教師手冊、習作本與測驗卷四大部分，除此之外更包含了動力機械課程各單元教學之電子檔與組裝程式，學生透過老師的導引、同儕之間的問題討論，並輔以適當的教學器材及課程輔具，相信對學生學習動力機械課程有極大的助益。

Recent educational research had turned the emphasis on the abilities of pupils’ skills into the abilities of pupils’ problem solving in a collaborative way in science education. Thus, one of the aims of this study is to investigate the teaching approach of the ‘Collaborative Problem Solving’ (CPS) in depth. Furthermore, this study also aims to apply the CPS approach into the course design of Power Mechanics for primary education. As the significant contributions, this study successfully integrated the CPS approach with the course of Power Mechanics for primary education and developed four main components for this curriculum: teacher’s guidebook, student’s textbook, assignment and the test for students.
