摘要 数学学习的基础是正确理解每一个概念,概念学习本质是对概念属性的辨认,而例子则是概念属性的具体化和形象化,包括正例与反例,对概念学习有重要的辅助作用.教师在教学时偏重从正面解释概念且举例形式不丰富,学生往往理解不透彻,抓不住它的本质属性.本文正是研究正反例强化策略在数学概念教学中的应用,实质是结合概念的特征,依据概念获得的两种方式,从而指出构造正反例的时机、方法及数量,来帮助学生理解和掌握概念. 该论文有参考文献 5篇。 50837 毕业论文关键词:正例 反例 策略 数学概念教学 The Application of Reinforcement Strategy about Positive and Negative Examples in Mathematics Concept Teaching Abstract The foundation of mathematics learning is to understand each concept correctly. The essence of concept learning is to identify attributes and examples are specific and vivid attributes, including positive and negative examples. Examples play an important role in concept learning. Teachers put emphasis on positive interpretations of the concept in teaching, and they don’t provide various forms of examples. So that, students often do not understand concepts thoroughly, which means that they can’t grasp the essential attributes of a concept. The Application of Reinforcement Strategy about Positive and Negative Examples in Mathematics Concept Teaching is discussed in this paper. The essence is combining with features of a concept, according to the two ways of getting a concept. It is pointed out the structure of the time, methods and quantities of positive and negative examples, to help students understand and master the concept.
