新的课程标准理念要求,学科课程必须与信息技术整合。信息技术在中学物理教学中的应用有其独特的优势,利用多媒体技法,可以使许多复杂的物理问题变难为易,从而减轻教学负担,提高教学效率。下文仅就简化电路实现电阻等效问题,来说明如何利用多媒体的动静变化、遮掩还原、压缩放大等技法来优化教学方法。选题一:如图甲,学生在学习电路时,弄清它们是并联 The new curriculum standard philosophy requires that subject curricula be integrated with information technology. The application of information technology in secondary school physics teaching has its unique advantages. Using multimedia techniques can make many complex physical problems become difficult, thus reducing the teaching burden and improving teaching efficiency. The following only to simplify the circuit to achieve resistance equivalent problem, to illustrate how to make use of multimedia dynamic changes, cover reduction, compression and amplification techniques to optimize teaching methods. Topic 1: Figure A, students learn the circuit, make it clear that they are in parallel
