【摘要】：随着新课程改革的推行,教学方式的变革渐入人心,数学探究教学越来越受到数学教育者的重视。现代信息技术在课堂中的运用为改变教学方式、提高课堂教学的效率提供了技术支持。同时,国家也非常重视信息技术与课程教学整合,因此很多动态软件被应用到数学教学中来,尤其是几何画板的应用十分广泛。因几何画板数学功能强大,操作简单,所以深受广大学者和一线教师的喜爱,这为开展数学探究教学提供了良好的契机。基于此,笔者将初中数学探究教学与几何画板结合起来,从而开展基于几何画板的初中数学探究教学的研究。本文研究的问题是基于几何画板的初中数学探究教学。首先,笔者回顾了数学探究教学的相关理论,梳理了几何画板在初中数学教学中的应用现状,并总结了几何画板的特点、功能。其次,通过分析《义务教育数学课程标准》,提出了在初中数学中开展探究教学的选材原则:选取的内容须具有探究的价值;选取的内容应体现知识的形成过程;选取的内容要适度。然后,根据这些原则选出初中数学教材中适合基用几何画板探究的内容,再结合不同类型的数学课程、几何画板的背景及探究教学的特点,笔者构建了初中数学探究教学的一般流程,探讨了适合于几何画板的探究教学模式:综合实践的教学模式以及课内问题的教学模式。对教学模式中的各个教学环节进行了详细阐述,提出了在开展初中数学探究教学时的教学策略:激发探究动机;掌握探究技能;学会提出问题;营造探究氛围;避免假伪探究。最后,笔者根据所设计的教学模式开发出若干个典型的教学案例。本人研究的主要成果包括以下三个方面:1.提出了在初中数学中开展探究教学的选材原则;2.探讨在几何画板背景下适用于数学不同类型课的探究教学模式且阐述在实施探究教学过程中的教学策略;3.根据探究教学的模式以及教学的策略设计出若干个典型的教学案例,以供使用。
[Abstract]:With the implementation of the new curriculum reform, teaching methods change gradually into people's minds, mathematics inquiry teaching has attracted more and more attention to mathematics education. The use of modern information technology in the classroom to change the teaching way, provide technical support to improve the efficiency of classroom teaching. At the same time, the state attaches great importance to the teaching of information technology and curriculum integration, therefore a lot of dynamic software has been applied to mathematics teaching, especially the application of the Geometer's Sketchpad is very extensive. Because of the Geometer ssketchpad powerful, simple operation, so the majority of scholars and teachers alike, which provides a good opportunity for developing mathematical inquiry teaching. Based on this, the junior high school mathematics inquiry teaching with geometry in order to carry out research on Geometric Sketchpad, Sketchpad based on junior high school mathematics inquiry teaching. This paper studied the problem of the junior high school mathematics inquiry teaching Sketchpad based on . first, the author reviews the theory of mathematics inquiry teaching, combing the application of the Geometer's Sketchpad in mathematics teaching in junior high school, and summarizes the characteristics of the Geometer's Sketchpad function. Secondly, through the analysis of "compulsory education mathematics curriculum standard", puts forward the principles of inquiry teaching in junior middle school mathematics: selected the content must have research value; the content should reflect the process of knowledge formation; selection of content should be moderate. Then, according to the study by the Geometer's Sketchpad for base content of the principle of selected junior middle school mathematics teaching, mathematics course again different types, and explore the background of the Geometer's Sketchpad teaching characteristics, the author constructed the general process of junior high school mathematics inquiry teaching, discusses the teaching mode suitable for the Geometer's Sketchpad: comprehensive practice teaching mode and teaching mode in class problem. The teaching mode The teaching in detail, put forward to carry out inquiry teaching in junior high school mathematics teaching strategy: arousing inquiry motivation; mastery of skills; learn to question; create inquiry atmosphere; to avoid pseudo inquiry. Finally, according to the design of the teaching mode to develop several typical teaching cases. I mainly the research includes the following three aspects: 1. puts forward the selection principles of inquiry teaching in junior middle school mathematics study in 2.; under the background of the Geometer's Sketchpad applies to math class of different types of inquiry teaching mode and exploration in the teaching process of teaching strategies in the implementation; 3. according to the inquiry teaching mode and teaching strategy design several typical teaching cases for use.
