上自然课时,很多老师都希望学生在自主探究的过程中,能把自己辛苦准备的材料充分运用到实验中去,使教学环节井然有序,教师轻松、顺利地驾驭课堂。然而在实际教学中,由于学生思维的差异,他们在研究过程中往往出现不同的方法,使用不同的材料,甚至有些材料根本不用,这也可以算是创新的表现吧。 On the nature class, many teachers hope that students can make full use of their hard-prepared materials in the experiment in the process of self-exploration so that the teaching links can be organized and teachers can easily and smoothly manage the classroom. However, in practical teaching, due to the differences of students' thinking, they tend to have different methods in the research process, using different materials, even some of the materials do not, which can be regarded as innovative performance.
