小学教育-小学数学第一学段＂图形与几何＂教学策略探究论文

摘 要“图形与几何”是构成小学数学课程体系的重要成分。但在实际教育活动中学生的几何素养和空间观念距离课标要求仍有较强的差距。如何提高“图形与几何”的教学效果，增强学生的空间思维能力成为了一线教师的研究新潮。从教学策略理论观点出发，梳理国内外有关该领域的教学研究现状。选定了第一学段“图形与几何”的课堂教学策略为研究对象。以课堂观察为探究内容，考察教学准备、实施和评价这三方面策略开展情况。针对“图形与几何”教学中存在的问题，凝炼出以学生思维发展特点为前提，调动学生学习几何的积极性，促进其空间观念发展的改进教学策略。关键词：第一学段；图形与几何；教学策略Abstract“figures and geometry” are an important component of the primary school mathematics Curriculum system. However, in the actual educational activities, there is still a strong gap between students’ Geometric library and space concepts and the requirements of Curriculum standard. How to improve the teaching effect of figure and geometry and enhance the students is. Starting from the theoretical point of view of teaching strategy this paper reviews the current situation of teaching research in this field at home and abroad. The classroom teaching strategy of figure and geometry in the first stage is selected as the research object. Taking classroom observation as the content of inquiry this is paper. investigating is the implementation of the three strategies. Of teaching preparation, implementation and eve. Location in view of the problems is existing in the teaching of figure and geometry this paper puts forward the improved teaching strategy based on the characteristic is of students’ thinking development. arousing students’ enthusiasm in learning, geometry and promoting the development of their space concept.Key words: The first paragraph; Figure and geometry; Instructional strategy目 录引言.............................................
