人教版《数学》八年级下册有一图形(如图1).在教学中,可从图1及其变式中设计一系列探索性问题,来引导学生探究平行四边形的其它性质,让学生通过探究来挖掘平行四边形性质之间的内在联系,以形成知识组块,从而提高解题能力,发展思考力.请看下面的教学片断及教学思考.一、教学过程师:回顾我们已经学过的平行四边形性质(对边相等,对角相等)的研究过程,你发现了有哪些思考问题的规律?
PEP teaching mathematics eighth grade under a graphics (Figure 1) in teaching, from Figure 1 and its variants in the design of a series of exploratory questions to guide students to explore other properties of the parallelogram, so that students Through inquiry to explore the nature of the parallelogram between the intrinsic link in order to form a knowledge block, thereby enhancing the ability to solve problems, develop the ability of thinking.Please see the following teaching fragments and teaching thinking.Part One, teaching process: review we have learned Of the parallelogram of the nature (on the same side, equal to the diagonal) of the research process, you found what are the rules of thinking?
