一、通过演示实验培养学生的观察、思维能力1.教师要操作规范、程序有条理,现象明显生动,以身示范陶冶学生对物理实验的兴趣,培养学生崇尚科学的思想意识.2.要以培养观察、思维能力为重点目标.因此,在演示实验中,要展现条理清晰的物理图景,使之有利于学生在观察的基础上推进思维活动深入发展.例如,为阐明声音是怎样发生的,应做“发声体在振动的演示实验.”先将悬吊的塑料球接触不发声的音叉,而后接触敲响
First, through the demonstration experiment to develop students’ observation, thinking ability 1. Teachers should operate the norms, procedures are organized, the phenomenon is vivid, to demonstrate the students’ interest in physics experiments, to cultivate students’ ideology of advocating science.2. Training observation and thinking ability are the key objectives. Therefore, in the demonstration experiment, it is necessary to demonstrate a clear physical picture so that students can promote the in-depth development of thinking activities on the basis of observation. For example, to clarify how the sound occurs, The “sounding body’s demonstration experiment in vibration should be done.” First, the suspended plastic ball should contact the unvoiced tuning fork, and then the contact sounds.
