课堂是课程与教学变革的主阵地。如何变革课堂,启迪学生智慧,把学生从“死”的知识中解放出来,获得再创造的自由,是初中物理课堂教学中要积极思考的。传统的《密度的应用》教学,重在利用密度公式进行变式计算的训练,而这些死板单调的知识灌输,对生活在时时刻刻不断接受着新事物的学生来说,已然不能产生任何兴趣。何不从学生的生活出发,调动学生的现有感知、认知体验,进而引发他们对知识的好奇与探索?
Classrooms are the main front for curriculum and teaching reform. How to change the classroom, enlighten students’ wisdom, liberate the students from the knowledge of “death ” and obtain the freedom to recreate are the positive thinking in junior middle school physics classroom teaching. The traditional teaching of “application of density” focuses on the training of variation calculation using density formulas. These inflexible and instilling knowledge are no longer of any interest to students living constantly receiving new things constantly . Why not start from the student’s life, to mobilize the students’ current perception, cognitive experience, and then lead them to the curiosity and exploration of knowledge?
