在学生的数学学习中,有些知识需要我们引导、讲解,有些知识应该放手让学生自己探索、寻找,在教学中,教师应如何把握教学的“授”与“放”呢?根据知识的生成结构,小学数学基础知识可分成三种:工具型知识、规律型知识、经验型知识。下面我们就这三种类型的基础知识及其在教学中的处理展开具体分析。一、主要特征及教学处理1.工具型知识这类知识是学生必备的知识,是后续学习的基础,不具备这些知识,后续学习就会受阻。比如:“数”的教学中的数数、写数、读数,
In the mathematics study of the student, some knowledge needs us to guide, explain, some knowledge should let the student explore by oneself, look for, in the teaching, how should the teacher grasp the teaching “teaching” and “putting”? According to The formation of knowledge structure, elementary mathematics can be divided into three basic knowledge: tool-based knowledge, regular knowledge, empirical knowledge. Below we have a detailed analysis of these three types of basic knowledge and its teaching in the process. First, the main features and teaching 1. Tool-based knowledge This knowledge is necessary for students knowledge is the basis for follow-up study, do not have this knowledge, follow-up study will be blocked. For example: “number ” in teaching the number of, write number, readings,
