在新课程改革背景下,新的教学方法层出不穷,包括问题化教学、探究式教学、合作式教学等。在课堂上,情景和问题只是手段,而活动既是手段又是目的。学生是活动的主体,教师起引导启发、指导帮助作用。有效开展合作学习能解决细节问题,体验物理情感,收获思想方法,领会科学本质。 In the context of the new curriculum reform, new teaching methods emerge in an endless stream, including problem-based teaching, inquiry-based teaching and cooperative teaching. In class, situations and problems are just instruments, and activity is both means and purpose. Students are the main part of the activity. Teachers play a leading role in guiding and helping. Effective cooperation in learning can solve the details of the problem, experience the physical emotion, harvest ideas and methods, understand the nature of science.
