备课是教学的一个重要环节,而对教材的“挖掘”与“处理”又是备课中的重要一步;对教材“挖掘”、“处理”是否得当,直接影响课堂教学中对重难点的突破、直至教学效果,因此十分重要.下面笔者结合自己的教学实践体会,谈谈这方面的认识. Preparing lessons is an important part of teaching, and “digging” and “processing” of textbooks is also an important step in preparing lessons; whether teaching materials, “excavating”, and “processing” are appropriate affects the classroom directly.
