【摘要】：人类世界已经走入信息时代,伴随着计算机和网络技术日新月异的发展,我们生活和工作的方方面面都发生了巨大的变革。图形计算器是一种适用于理科学习尤其是数学学科的专业的手持技术,图形计算器在近三十年来不断的更新换代中,其功能越来越丰富,并且具有操作简单和便于携带等优势,已经越来越多的应用于国内外的数学教学和数学学习之中。函数是高中数学中极为重要的部分,它的思想方法贯串高中代数的始终,但是由于函数的抽象性和复杂性,对于高中生来说,函数部分既是重点又是难点。图形计算器这一新的手持技术引入高中数学课堂后,不仅仅改变了教师教的方式,而且改变了学生学的方式。在高中函数的学习方面,图形计算器能够提供专业的技术支持,是教师教和学生学的得力助手,为数学实验提供了平台,为学生自主探究提供了工具。本文以皮亚杰的建构主义学习理论和杜威的“新三中心论”以及布鲁纳的发现学习理论为基础,结合我国新课程改革的理念和要求,通过自身使用图形计算器与函数部分进行整合的教学实践,以及对学生和听课教师的调查和反馈,主要得出以下结论：1、学生乐于接受图形计算器,图形计算器的介入对高中生函数学习起到了促进作用,优化了学生的学习方式。2、教师要更新观念,提高操作水平,改进教学方法,鼓励学生开展数学实验,提高学生运用图形计算器分析和研究函数问题的能力。图形计算器的介入有助于提高教学效果。
[Abstract]:The human world has entered the information age, with the rapid development of computer and network technology. Great changes have taken place in all aspects of our lives and work. Graphic calculators are a professional handheld technology for science studies, especially mathematics. In the past 30 years, the graphic calculator has more and more functions, and has the advantages of simple operation and easy to carry. Function is a very important part of senior high school mathematics, and its thought method runs through the whole course of high school algebra. But because of the abstractness and complexity of the function, the function part is not only the focus but also the difficulty for the senior high school students. The graphics calculator, a new handheld technology, is introduced into the mathematics classroom of the senior high school. It not only changes the way teachers teach, but also changes the way students learn. In the study of high school functions, graphic calculators can provide professional technical support, and are the right assistants for teachers and students to learn. This paper is based on Piaget's constructivism learning theory, Dewey's "new three-center theory" and Bruner's discovery learning theory. Combined with the concept and requirements of the new curriculum reform in our country, through the teaching practice of integrating the graphic calculator with the function part, as well as the investigation and feedback to the students and the teachers, the following conclusions are drawn: 1. Students are willing to accept graphics calculators, the involvement of graphics calculators to high school students function learning has played a role in promoting the optimization of students' learning methods. 2, teachers should update their concepts, improve the level of operation. Improving teaching methods, encouraging students to carry out mathematical experiments, and improving students' ability to analyze and study function problems by means of graphic calculators, the intervention of graphic calculators will help to improve the teaching effect.
