现代教学观认为,数学教学的本质是思维活动。因而, 数学教学必须按照数学教学的思维活动规律来进行,也就是说,数学教学必须体现数学思维过程。在实际教学中,大部分课的结构基本上是使用“以讲为主、练习为辅、先讲后练”的模式。而“三份作业”提出的课堂教学模式与传统的“讲一练”模式相反,是一种“练一讲”模式,即过去是以讲为主,现在要求以练为主;过去是先讲后练,现在要求先练后讲,并且把讲和练结合起来,边练边讲,寓讲于练。根据实践,我在教学中摸索出“三份作
The view of modern teaching thinks that the essence of mathematics teaching is thinking activity. Therefore, mathematics teaching must follow the laws of mathematics teaching activities to carry out, that is, mathematics teaching must reflect the mathematical thinking process. In actual teaching, the structure of most of the courses basically uses the mode of “emphasizing on speaking, supplemented by practice, and speaking after practice.” The “three assignments” put forward the classroom teaching model and the traditional “talk a practice” mode is opposite, is a “practice a talk” mode, that is based on the past speaking, and now requires training to practice; the past is the first Speaking after practice, now requires that after the first practice, and stresses and practice together, while practicing while speaking, speak in practice. According to practice, I worked out three teaching in teaching
