怎样讲清基本概念?这里结合《政治经济学常识》的教学,谈几点做法和体会。 一、深入钻研教材,找出重点和难点 在教学中,我特别重视钻研教材。每讲一节课,我力求突出重点,突破难点。如讲商品的二重性,我确定以商品的价值作为一个难点和重点来讲授。在讲清价值的概念的基础上,用实例进一步说明,然后阐明价值是通过什么形式来表现的,最后进行小结。 二、抓住关键词句讲清基本概念 为了讲清“商品”这个概念,我抓住“劳动产品”和“用来交换”这两个关键词句加以说明。首先说明商品必须是劳动产品。但劳动产品,并不就是商品,只有“用来交换”的劳动产品才能成为商品。例如,粮食是劳动产品,但只是为自己消费而生产的粮食,就不是商品。只有当农民把它拿到市场上去卖掉,以换回其他生 How to make clear the basic concepts? Here we combine the teaching of “Political Economics Common Sense” and talk about some practices and experiences. I. Drilling into the teaching materials to identify key points and difficulties In teaching, I pay special attention to studying teaching materials. Each lesson, I strive to highlight the key points and break through the difficulties. As for the duality of commodities, I have determined that the value of commodities is a difficult and important point to teach. On the basis of clarifying the concept of value, using examples to further explain, and then clarify the value is expressed in what form, and finally to make a summary. Second, seize the key words to clarify the basic concepts In order to clarify the concept of “goods”, I seize the “labor product” and “used to exchange” these two keywords to illustrate. First of all, it means that the product must be a labor product. However, labor products are not commodities. Only labor products used for “exchange” can become commodities. For example, food is a product of labor, but food produced for its own consumption is not a commodity. Only when the farmers take it to the market and sell it in exchange for other students
