About the role of information technology in the high school mathematics teaching

IT human understanding in the production and scientific experiment and change nature and accumulated to obtain information, to transmit information, store information, process information, and the information standardization experience, knowledge, skills, and reflect the experience, knowledge, skills, labor The information the purpose of the binding process.

Educational psychology: people access to outside information, 83% from the visual, 11% from the hearing, and 3.5% from the sense of smell, and 1.5% from tactile, and 1% from the taste. Obviously, increased visual, auditory amount of information people get the most desirable amount of information the new curriculum standards that: “IT should be powerful tool for learning math and problem-solving as a student, working to change the way students learn, so that students happy and have more energy into reality, the exploratory teaching activities. “the author will combine the integration of information technology and mathematics teaching methods, has done some preliminary discussion.

The traditional teaching is mainly explained by teachers the analytical mathematical knowledge, inspired induce students to understand math, but students how to grasp the extent of the individual will have to see the potential and ability to understand abstract mathematical knowledge to take advantage of changes in information technology demonstrate the process and a result, changing one of the variables, changed and unchanged in the observations which seize the mathematical nature of the problem, understanding so intuitive appearance to the depth, abstract from special specific to the general, from the summarized guessed reasoning proved that changed in the past only focus on the transmission of knowledge, and more knowledge-generating process of experiment and explore this improvement of teaching methods makes it easier for students to understand and master mathematics, to promote the development of mathematical thinking ability, obviously the IT and high school mathematics curriculum integration is necessary ‘s.

First, information technology can be used as information processing tool In life, we will always take advantage of a variety of information, we deem valuable information after the processing of information selected Of course, this information needs to be stored and transmitted in this process, we often use information technology to obtain information processing information, storing transmit information, the IT Information processing tool.

First need in the teaching of mathematics integrated implementation of the teaching content of information processing, the formation of learning resources, information technology environment to start teaching students to use information technology to gain valuable information and knowledge, to construct the final completion of the significance of knowledge. IT build learning resources and to be able to store a repository, the use of information technology can build the platform of the transfer and exchange of information resources, teachers and students together to complete the learning task. provides a wealth of background information technology for mathematics teaching design, allows students to give full play to the visual auditory, tactile and other sensory synergy and more effective math learning.

IT is an effective cognitive tools Constructivist theory of “cognitive tools” that learning is thinking as an intermediary, has been overly concerned with technology transfer in order to more directly affect the learning process, should be reduced, and more concerned about how to accomplish different tasks require learning by thinking technology. cognitive the tool theory is born out of this on the basis of cognitive tool support, guidance, expansion of the the learners thinking process of psychological or computing device. former exists in the learner’s cognitive element recognized knowledge strategy, which is external, including computer-based devices and the environment, they are aid into a tool of knowledge construction. multimedia teaching technology and network technology as the core of modern information technology to become the best, most practical cognitive tools IT curriculum integration, emphasis on IT services in specific tasks, students in a natural way to treat IT as access to information, to explore the issues, collaborative problem-solving cognitive tools, and the use of such tools as smoothly like pencils, erasers, natural to cultivate the students to learn IT as access to information, explore issues, collaborative discussion, cognitive tool for problem-solving and knowledge building, information technology as a presentation tool, communication tools, individual counseling tools scenarios to explore and discover learning tools, information processing and knowledge building tools, collaboration tools, development tools, emotional incentive tools.

IT conducive to embody a mathematical way of thinking Shuxingjiege is an important mathematical thinking IT can take the initiative to design number, shape dynamic presentation characteristics, given the unique charm of knowledge. Rapidly changing variables, synchronization screen graphic changes, or screen. graphical gradient, window synchronization variable changes, and the demo process can be controlled as needed the demo speed can be adjusted, you can see a number of changes in a variety of situations at any time or unchanged, graphics dynamic or static, the “number of “and” shape “of the potential relationship dynamically displayed so that teachers can be rendered in a targeted manner to explain or organizations to discuss and guide students observed in accordance with the contents of the various variables, validation, comparison, find the general and special attributes, so that students can deepen the perception of geometry, keen to seize the change characteristics really modern information technology to assist teaching.

For example: conic unit teaching objectives through the the cone curve of learning, to enable students to further understand the algebraic language to describe geometric elements and their relationships, and thus the geometric problems into algebraic problems to deal with algebra problems, the geometric algebra results meaning the final solve geometric problems, feel conic portray the real world and solve practical problems in, further experience Shuxingjiege thought.

Oval lesson teaching objectives there are two lines: open-wire is the definition of an ellipse elliptic equation and its simple, dark line through the ellipse defined teaching the the students learn Shuxingjiege thought, by the Institute of the derivation of the elliptic equations algebraic geometry problems of the ideas and methods to cultivate the ability of students to explore issues.
