随着新课程标准的全面贯彻实施,传统的实验仪器已跟不上教材变化的需要。新的中学物理教材新增了大量的演示实验。由于仪器的开发相对于课本而言,具有明显的滞后性,一时不能满足教学的需要,教具(学具)的设计与制作已成为填补这一空白的重要手段。 With the full implementation of the new curriculum standards, the traditional experimental equipment can not keep up with the changing needs of teaching materials. New high school physics textbooks added a large number of demonstration experiments. Since the development of instruments is obviously lagging behind that of textbooks, it can not meet the needs of teaching for a short time. The design and production of teaching aids have become an important means to fill this gap.
