曲靖师范学院 本科生毕业论文 论文题目：小学数学问题情境创设的误区和对策 作者、学号： 学院、年级：教师教育学院 学科、专业：教育学 小学教育（数学与科学方向） 指 导 教 师： 完 成 日 期： 年5月20日 曲靖师范学院教务处 小学数学问题情境创设的误区和对策 摘要 小学数学教学中创设问题情境是改革实验教科书的一大亮点，新奇、灵活、巧妙、有趣、富有针对性的问题情境不仅促进学生的数学思考，而且使教学如鱼得水，取得事半功倍的良效。相反，问题情境的创设华而不实、离题万里、枯燥乏味、牵强附会便会事与愿违，适得其反，这样不仅冲淡了数学课应有的数学味，可能还会导致课堂教学目标未能及时实现，从而影响教学的进度。本文针对新课改下教师在创设问题情境时，缺失实效性、目的性、趣味性、数学性、科学性诸多误区进行反思和分析，然后详细诠释问题情境正确理解问题情境，最后提出通过变花哨为内涵，精选信息 ，设计矛盾、趣味和悬念的问题情境，凸显情境的数学味，紧扣学科教学目标等多种创设有效问题情境的对策，进而让教师们正确理解问题情境，尽快走出创设的误区。 关键词：小学数学；问题情境；误区；对策 The Erroneous Zones and Countermeasures of Creating Problem-Situation in Elementary School Math Abstract: Producing problem-situations is a highlight of the textbook for elementary school Mathematics teaching reform experiment. Original, flexible, clever, interesting, and suitable to the problem-situations not only promotes the students mathematical thinking, but also makes the teaching procedure ahead of the time. On the contrary, those problem-situations with flashy, reverse, boring and far-fetched will backfire our teaching aims, it could give less prominence to math leaning environment and cause teaching aims fail to come true on time, influence the teaching according to schedule. This article will reflect and analyze those erroneous zones ,such as actual effect, issue, interests, Mathematics and sciences ,what had lost by teacher in the new teaching reform experiment, then explain elaborately the real meaning of problem-situations and finally put forward effective countermeasures to the problem situations via selecting information, designing contradictory, interesting, suspenseful problem-situations, highlighting the situation of mathematics taste, fastening of teaching objective, etc. And let the teachers have a correct understanding of the situation to get out of the promotion of the major traps as soon as possible. Key words: elementary school math; problem-situation; erroneous zones; countermeasures 目录 引言…………………………………………………………………………………… 1 研究方法…………………………………………………………
