初中化学基本概念又是学生学习基础理论、元素化合物、实验和化学计算等化学知识的基础,没有这些基础,要想学好化学是不可能的。在现行初中化学教材中,有许多精炼的化学概念,这些概念是用简练的语言高度概括出来的,常包括定义、原理、反应规律等。初中学生的阅读和理解能力都有待培养和提高,因此,在教学过程中讲清概念,把好这一关是非常重要和必要的。如何更好地进行化学基本概念的教学,本人在平时的教学中做了如下尝试:
The basic concepts of junior high school chemistry are also the basis for students to learn basic theories, elemental compounds, experiments and chemical calculations and other chemical knowledge. Without these foundations, it is impossible to learn chemistry well. In the current junior high school chemistry textbook, there are many refined chemical concepts. These concepts are highly summarized in concise language, often including definitions, principles and reaction rules. The reading and comprehension ability of junior high school students needs to be nurtured and improved. Therefore, it is very important and necessary to clarify the concepts in the process of teaching so that they can get the job done. How to better carry out the basic concepts of chemistry teaching, I made the following attempts in the usual teaching:
