兴趣是学生学习的内在动力,巧用实验情境、生活情境、问题情境、故事情境,可充分调动学生的探究欲望,培养学生的探索精神。因此,教师要尽可能地挖掘教材中的趣味因素,培养学生探究化学问题的兴趣和自信心。 Interest is the intrinsic motivation for students to learn. By using experimental situations, living situations, problem situations and story situations, students can fully mobilize the exploration desire of students and develop students’ exploration spirit. Therefore, teachers should try their best to excavate the interesting factors in teaching materials and cultivate students’ interest and confidence in exploring chemical problems.
