摘要
本课利用蚊子发声装置发出的"嗡嗡"声引入新课,在观察、比较、分析,归纳概括中建立声音是由物体振动产生的科学概念,提升学生多感官观察、比较、归纳、概括能力,激发了学生研究声音的学习兴趣。在引导学生认识声音的产生时,提高学生的参与度,让他们在愉快的制作和玩耍过程中探究声音产生的根本原因,建构正确的科学概念。
This lesson introduces the"buzz"sound from the mosquito vocal device into the new lesson,establishes the scientific concept that sound is produced by object vibration in observation,comparison,analysis and generalization,improves students’ability of multi sensory observation,comparison,induction and generalization,and stimulates students’interest in studying sound.When guiding students to understand the production of sound,we should improve students’participation,let them explore the root causes of sound production in the process of happy production and play,and construct correct scientific concepts.
