鑄造單元實習教具之開發及其應用

Abstract

研究者身為鑄造科教師多年教學發現，在教授機械製造科目鑄造單元時，由於鑄造程序的抽象概念，多數機械群學生無法理解。在新課綱機械群增加鑄造單元實習課程，礙於學校添購鑄造設備經費與規劃教學場地之問題。 本研究將鑄造單元實習教具縮小化、輕便化與實體化，自製一套簡易鑄造單元實習之教具，使教學教具不受時間、地點限制，故機械群的學生可以隨時使用操作教具，有效提升學生學習行動力。讓學生達到做中學、學中思，以提升學習成效，也能解決技術型高中機械群課程設備經費與場地問題。 本自製教具相較傳於統鑄造單元實習設備有以下四項大突破： 一、教具成本低（約相差793倍）。 二、教具重量輕（約相差406倍）。 三、教具體積小（約相差1180倍）。 四、具有行動力，不受時間、地點限制。 關鍵詞：機械群、鑄造實習、做中學According to the years of my teaching experiences as a foundry teacher, the unit of foundry practicium has been taught in the subject of mechanical production still, most mechanics students can’t get a whole picture due to the abstract concepts of foundry procedures and thus they have no choice but to quit learning. In addition, the foundry practicium has been added to the latest standard curricula. However, its teaching is hindered by the problems that teachinical high schools have insufficient funding for foundry equipment or lack proper teaching fields. In this study, I attempt to make the teaching aids for foundry practicium smaller, more convenient, and more authentic. The set of simpler teaching aids for foundry practicium enables students to learn by doing and think by learning, so that more satisfactory learning results can be produced, and the problems of teaching equipment and fields for mechanics students in technical high schools can be solved. The following are the major innovations of the teaching aids that are created through this research , compared with traditional foundry practicium equipment: 1. The cost is a lot lower (by 793 times ). 2. The weight is a lot less (by 406 times ). 3. The size is a lot smaller (by 1180 times). 4. The mobility is a lot better, without any time or place limits.
