小学低年级数学“图形与几何”教学现状与改进策略研究 ——以徐州市 M 小学为例 摘要 图形与几何是小学数学四大领域之一，《义务教育数学课程标准》（2011 年版）对该 领域提出的要求是培养学生的空间观念，发展学生的几何直观和推理能力。然而在实际教学 中出现的问题是学生的几何素质不高，空间感薄弱的现象。因此如何开展“图形与几何”教 学，发展学生的几何能力和空间感成为所有小学数学老师思考的问题。本文试图从实际教学 的现状出发，对低年级“图形与几何”教学进行调查研究，旨在培养学生的空间观念和几何 能力，提高图形与几何教学的质量和学生的学习兴趣。文中运用问卷调查，访谈，观察这三 种研究方法针对教师对“图形与几何”教学目标、内容、方式、评价方式这四个方面进行了 有关“图形与几何”教学现状的调查及相关改进策略，全文共分为五个部分。 关键词 小学数学 图形与几何 低年级 Study on the teaching status and improvement strategy of "graphics and geometry" in lower grade mathematics inprimary school—— A case study of S Primary School in Xuzhou City Abstract Graphics and geometry are one of the four fields of elementary school mathematics, and the mathematics curriculum standards for compulsory education (2011 edition) is an important part of it The requirements of the field are to cultivate students' spatial concept and develop their geometric intuition and reasoning ability. However, the problems in the actual teaching are that students' geometry quality is not high and their sense of space is weak. Therefore, how to carry out "graphics and geometry" teaching and develop students' geometry ability and sense of space has become a problem for all elementary school mathematics teachers .Based on the actual teaching situation, this paper tries to investigate and study the "graphics and geometry" teaching in the lower grades, aiming at cultivating students' spatial concept and geometry ability, improving the quality of graphics and geometry teaching and students' interest in learning. In this paper, three research methods including questionnaire survey, interview and observation are used to investigate the current situation of "graphics and geometry" teaching and relevant improvement strategies from the four aspects of "graphics and geometry" teaching objectives, contents, methods and evaluation methods.
