新课标试行以来,由于热、光学等内容列入要求较低的选学内容,高考实验考核内容只剩下力学和电学内容。但几年来实验中的“新题”、“难题”迭出,实验题的得分仍很差。许多题虽均由课本原型实验改编而来,但已有一定的区别和提高,有的甚至面目全非,因此复习教学中注重实验的改进和拓展就显得非常重要。 Since the implementation of the new curriculum standards, due to thermal, optical and other content included in the lower elective content, college entrance examination only the content of mechanical and electrical test content examination. However, in recent years, the experimental “new title”, “problem” after another, the experimental question score is still poor. Although many of the questions are adapted from textual prototype experiments, but some differences have been made and some are even beyond recognition, it is very important to review experimentally-oriented improvements and extensions in teaching.
