摘要:随着教育事业的不断发展,新课程改革的实施,现代教育技术在学校中的应用越来越普及和广泛,制作及应用教学课件是将信息技术整合于数学课程教学的重要手段。为能更好的优化教学效果、提高教学效率,本研究选用美国Key Curriculum Press公司开发,中国人民教育出版社汉化的“几何画板”为开发工具,设计并制作初中数学教学案例资源。旨在利用信息技术工具,将初中数学教学化抽象为形象,化静态为动态,优化教学手段,丰富课堂内容,帮助学生理解,培养学生学习数学的兴趣,激发学生学习的主动性,开拓学生的思维能力,提高课堂教学效率,促进中学数学教学质量的提高。
本研究的主要内容是用“几何画板”创设情景,以帮助学生更好地理解数学材料。通过教师或学生操作“几何画板”,来“做数学”、开展几何数学,引导学生进行观察、猜测、验证、交流、概括、证明、应用,去研究几何数学教学现象与规律,以提高学生学数学的兴趣、增强理解能力、探究能力等。主要运用访谈法通过和学校里面个别的初中数学教师进行面对面的交流,了解他们的教学内容和教学方式。本设计的特色是运用“几何画板”制作初中数学中的函数和几何内容的案例,包含函数图象的变化、几何图形的移动、翻转及其动画等。
本文结构安排如下:1、阐述设计目的、设计意义、研究方法、国内外研究现状;2、初中数学课程概述(初中数学课程标准的理念目标、初中数学课程标准的基本要求、初中数学课程的教学特点、初中数学课程的教学要求);3、案例资源设计与实现(开发技术概述、案例设计、案例实现);4、总结与展望,评价与修改。

ABSTRACT:With the continuous development of education, the implementation of the new curriculum reform, the modern education technology in school is more and more widely applied and widely, making and application of courseware is the integration of ICT in mathematics curriculum teaching important means. In order to better optimize the effect of teaching, improve teaching efficiency, this study selects the United States of America Key Curriculum Press development, Chinese people's education press Chinese" geometry drawing board" for the development of tools, design and production of the junior middle school mathematics teaching resources. Aimed at the use of information technology tools, the junior middle school mathematics teaching for the abstract image of static, dynamic, optimizing teaching means, enrich the teaching contents, help the students to understand, to cultivate students' interest in mathematics learning, stimulate students' learning initiative, to develop the students thinking ability, improve the efficiency of classroom teaching, to promote the middle school mathematics teaching to improve the quality of.
The main content of this study is to use" geometry drawing board" the creation of scenarios, to help students better understand mathematics materials. The teacher or student" geometry drawing board", to" do the math", in geometry, guide the students to observe, guess, validation, AC, generalization, proof, application, to study geometry mathematics teaching phenomena and regularity, and to improve students' interest of studying mathematics, enhancing understanding ability, research ability. The main use of interviews and school through individual junior middle school mathematics teachers face to face communication, understanding of their teaching contents and teaching methods. This design feature is the use of" geometry drawing board" in junior middle school mathematics function and content of geometry case, contains the function image change, the geometry of the mobile, flip and animation.
This paper is structured as follows:1, elaborates the design objective, significance, research methods, design research status at home and abroad;2, the junior middle school mathematics curriculum outline ( junior middle school mathematics curriculum standard idea of target, the junior middle school mathematics curriculum standards of the basic requirements, the junior middle school mathematics curriculum teaching characteristic,the junior middle school mathematics curriculum teaching request );3, case resource design and implementation of ( development of technology, case-based design, case implementation );4, summary and outlook, evaluation and modification.
