【摘 要】随着最新课程标准的改革与发展,对初中数学几何教学也提出了新的要求,应试教育束缚下的“填鸭式”教学模式已不再适应创新教育要求。为更好培养学生的创新思维,提高课堂教学效率与质量,新课标下的教学大纲要求教师必须创新课堂教学模式,借助多媒体等各项教学设备,引领学生自主思考,提高学生的数学几何图形分析能力。所以本文基于此背景下,分析当前初中数学几何教学中存在的问题以及具体的教学策略,旨在改进初中数学教学工作,以适应创新教育主题,引导学生自主思考。

【Abstract】With the reform and development of the latest curriculum standards, new requirements are put forward for junior high school mathematics geometry teaching. The "cramming" teaching mode under the shackles of exam oriented education no longer meets the requirements of innovative education. In order to better cultivate students' innovative thinking and improve the efficiency and quality of classroom teaching, The teaching syllabus under the new curriculum standard requires teachers to innovate the classroom teaching mode, with the help of multimedia and other teaching equipment, guide students to think independently and improve students' mathematical geometry analysis ability. Therefore, based on this background, this paper analyzes the problems existing in the current junior high school mathematics geometry teaching and specific teaching strategies, aiming to improve junior high school mathematics teaching, to adapt to the theme of innovative education and guide students to think independently.

一、初中幾何教学中存在的问题
(一)教学方式老旧
初中几何传统教学缺乏创新思维,教学设施落后,教学方法陈旧,仅靠老师拿着一根粉笔在黑板板书式的讲解很难将几何的多面体空间性体现出来,再加上初中学生通常空间立体感不强,因此很难学好几何内容。随着科学技术的进步,教学设施也在不断更新,幕布多媒体教学逐步进入初中几何教学,但是几何图形也仅仅是平面展示,教学设备的更新没有从根本上改变教学方式,初中几何教学依然枯燥无趣,难以调动学生的学习兴趣,无法有效提高学生学习效率。
(二)学生缺乏生活经验
艺术来源于生活,初中教材中很多几何图形都可以在生活中找到实例,然而现阶段“两耳不闻窗外事,一心只读圣贤书”的教学模式,限制了初中学生生活体验,导致学生对生活中常见的几何图形认识不足。……
