科技时代,加强学生的科技素质培养刻不容缓。化学课应当充分利用实验教学,提高学生的科技素质。一、利用演示实验提高学生的观察力化学是以实验为手段来研究物质及其变化的科学,是以观察物质及其变化为特征的,因而在化学实验中培养学生的观察力是极其重要的。如何在化学实验教学中更好地培养学生的观察能力呢?演示实验是教学成功的前提。对于刚刚进入初三的学生来说,他们不能根据实验的目的去观察,在观察中带有很大的
In the age of science and technology, it is imperative to step up students’ cultivation of science and technology. Chemistry class should make full use of experimental teaching, improve students’ science and technology quality. First, the use of demonstration experiments to improve students ’observational chemistry is the means of experiment to study the matter and its changes in science, is based on the observation of the material and its changes are characterized, and thus in the chemical experiments to develop students’ observational power is extremely important . How to cultivate students’ observation ability better in chemistry experiment teaching? Demonstration experiment is the premise of teaching success. For students who have just entered the third grade, they can not observe for the purpose of experiment and have a large
