近年来,研究型学习在高中教育教学中蓬蓬勃勃地开展着,初中渗透研究型学习则以探究性为主。本文从初三化学实验着手,进行探究性教学的尝试,开放演示实验,大胆地把课堂演示实验让予学生,激发他们的情,调动他们的思,更重要的是培养学生的自信心和创新精神。在这基础上,把一些验证性实验改成探究性实验。 In recent years, research-based learning has flourished in the teaching of high school, and research-based learning in junior high school has been mainly exploratory. This article starts from the third chemistry experiment, tries to explore the teaching, opens the demonstration experiment, boldly gives the students the demonstration in the classroom, stimulates their feelings and mobilizes their thinking, and more importantly, cultivates students' self-confidence and innovation spirit. On this basis, some of the confirmatory experiments into exploratory experiments.
