中学化学实验过程的思维培养必须根据化学教学的要求 ,努力培养、发展学生思维能力素质的四个属性 ,即“敏捷性、严密性、整体性和创造性。”例如做下列实验 :图 1 实验前先检查实验装置的气密性。实验开始时 ,先关闭活塞ａ ,并取下烧瓶Ｂ ;向Ａ中加入一定量浓度适当的盐酸
The cultivation of the thinking in the middle school chemistry experiment process must be based on the requirements of chemistry teaching, and strive to cultivate and develop the four attributes of the students’ thinking ability quality, namely “agility, rigor, integrity, and creativity.” For example, the following experiments are performed: Figure 1 Before the experiment Check the air tightness of the experimental device first. At the beginning of the experiment, first close the piston a and remove the flask B; add a certain amount of hydrochloric acid with appropriate concentration to A.
