中学化学实验教学对学生能力的培养是多方面的。但我认为主要是培养学生的观察能力,思维能力和实验能力。本文就自己在这三方面的作法和体会谈点不成熟的看法,请同志们批评指正。一、引导学生正确地观察实验现象,培养学生观察能力敏锐而精确的观察,往往是创造性思维发展的先导。学生对化学实验现象感知越充分、完整,思维就越有源泉,就越有助于获得真正的知识。因此,培养观察能力,是培养其他能力的基础。怎样培养学生的观察能力呢? 1.分清主次,抓住本质。许多化学实验,其现象是复杂的。如果只是笼笼统统地要学生看实验,而不引导学生向着预定的总方向循序渐进的,有方向性的、有目的地观察,学生可能
The cultivation of students’ abilities in middle school chemistry experiment teaching is multifaceted. However, I think it is mainly to cultivate students’ observation ability, thinking ability and experimental ability. This article asks comrades to criticize and correct me for their immature views on the three aspects of the practice and the physical talks. First, to guide students to observe experimental phenomena correctly, and to develop students’ observational acuity that is sensitive and accurate is often a precursor to the development of creative thinking. The more complete and complete the students feel about the phenomenon of chemical experiments, the more active the thought is, and the more helpful it is to obtain true knowledge. Therefore, training observation ability is the basis for developing other abilities. How to develop students’ observation ability? 1. Distinguish between primary and secondary, grasp the essence. In many chemical experiments, the phenomenon is complicated. If you only want students to look at the experiment in a cage, and do not guide students toward the planned general direction, directional and purposeful observation, students may
