本文从一节《平面镜》实验展示课的两个场景对比谈起,阐述了物理实验的核心价值是培养学生的主动探究能力和学生的长远发展,而体现这种核心价值的关键点在于能否培养学生的评价和质疑习惯。纵观如今的物理实验课堂,教师往往只看重眼前有效,忽视评价和质疑习惯培养,正是这种看得见的“眼前有效”剥夺了孩子的评价和质疑习惯。 In this paper, we compare the two scenarios of a “flat mirror” experimental demonstration class, and expound that the core value of physics experiment is to cultivate students ’active exploration ability and students’ long-term development. The key point to reflect this core value lies in whether Develop students’ assessment and questioning habits. Throughout today’s physics experiment classroom, teachers tend to focus on the immediate validity, neglect of evaluation and questioning habits, it is this visible “immediate effect ” deprived of children’s evaluation and questioning habits.
