國中相似形翻轉教學之研究

本研究旨在探討翻轉教學之概念，及如何將此概念應用於教學上。本研究以相似形單元為例，根據現國民中學課本教材，進行教材研究之編制。本研究經由文獻探討與教材研究編制後，獲得以下結論: 一、編寫完整的教材，引導學生自主思考學習二、本研究教材編列步驟如下: (一)探討面積公式。 (二)利用面積大小的比較引入相似圖形。 (三)透過相似圖形比較邊角關係，引出相似之定義。 (四)利用圖形特徵比較導出相似概念之迷思。 (五)透過相似三角形與相似多邊形之圖形舉例探討其邊角關係。 (六)利用生活中的相似及相似活動，加深學生對相似概念的了解、應用。茲根據以上結論，提出幾點建議供教育單位參考:1.教師應對課程內容精熟，及具備良好的引導能力，以不斷調整課程內容，使學生能一步步進行探索；2.教學重點應放在如何讓學生能夠自己探索，讓學生從過程中找到對學習的熱情；3.此教學模式不宜放入太難課程，因課本上較深層概念較難用此模式進行，因此使用翻轉教學要特別注意較難部分應如何處理。

The purpose of this research are explore the concept of flipped classroom and how to apply to teaching. This study takes a similar form as an example to preparation of teaching materials based on Junior high school textbooks. After researching the literature and compiling the textbooks, this study obtained the following conclusions: Ⅰ. Compile the complete textbooks to guide students to think and study independently Ⅱ. The steps of this research for compiling textbook are as follows: (1)Explore the area formula. (2)Introduce the similar figures by compare area size. (3)Leading to the definition of similar by compare the corner relationship through similar figures, (4) Derive the myth of similar concepts by compare graphic features (5) Use similar triangles and similar polygons for example to explore the relationship between its corners. (6) Use similarities in life and similar activities to deepen students understand and apply similar concepts. Here are some suggestions for educational units to reference based on the above conclusions: 1. Teachers should be familiar with the content of the course and have good guiding ability to adjust the content of the course so that students can explore step by step; 2. The focus of teaching should be placed on how to allow students to explore on their own, so that students can find their passion for learning from the process; 3. This teaching mode should not be use difficult courses, because deeper concepts in textbooks are more difficult to use this mode, so pay attention to the use of flip teaching.
