为探讨通过教师的启发、指导,培养学生积极、主动地学习的路子,我们于1985年下半年至1986年上半年,在银川十五中初三化学课教学中,试行了以狠抓基础、培养能力为中心,以自学、实验为主要内容的“自学、实验、讲授、练习”四环节单元教学实验.现将实验情况介绍如下:一、基本做法(一)自学自学是“四环节”的基础,旨在培养学生的阅读能力和理解能力.主要步骤是:1.印发切合学生实际,紧扣教材的自学提纲.提纲以基础题为主,适应配合一些综合性题.如氢气的实验室制法一节,安排两课时讲完,第二课时自学提纲如下:(1)启普发生器由几部分组成?(2)锌粒和稀硫酸各从什么地方放入?(3)反应在
In order to explore ways of cultivating students’ active and active learning through the inspiration and guidance of teachers, we tried to pay attention to the basics in the third half of 1985 to the first half of 1986. The four-unit teaching experiment of “self-study, experiment, lecture, and practice” centered on self-learning and experimentation is the main content of self-learning and experiment. Now the experimental situation is described as follows: 1. Basic practice (1) Self-study is “four links” The basic aim is to cultivate students’ reading ability and comprehension ability. The main steps are: 1. To publish a self-study curriculum that meets the students’ needs and closely follows the teaching materials. The outline is based on the basic questions and is adapted to meet a number of comprehensive questions. Such as the hydrogen laboratory. In the section on the method of production, two classes are arranged and the second lesson is self-study. The outline is as follows: (1) What is the composition of the Kaipu generator? (2) Where are the zinc particles and dilute sulfuric acid put in? (3) The reaction is
