The Application Of Information-based Teaching Methods In High School Mathematics Class

With the use and promotion of the new teaching materials and new curriculum reform,the demands for talents of the 21st century will highlight the comprehensive abilities of "using the obtained electronic information","mastering new technology","applying systematic methods",etc.In the process of cultivating learners,means of education have changed from the traditional ways of teachers",showing charts","relying on chalk",and "oral explanation" to the computer-based multimedia,broadcast,projectors,televisions and other modern teaching models.Information-based teaching methods pay more attention to the student's subject position.It can fully mobilize the students' enthusiasm and initiative in learning,and make the students to be more creative and think positively.It can also help to cultivate the students' all-round development.Although the teachers and students have gradually noticed the differences and gaps between the traditional and modern teaching methods,and have made choices during the actual teaching process,neither have they formed a complete systematic understanding nor conducted detailed researches of the information-based teaching methods in the practical application.Trigonometric function is one of the important contents in middle school mathematics.Its research method is mainly the formula deformation and image transformation in algebra and it has also preliminarily connected algebra with geometry.Trigonometric function is an important part of high school function learning.This article takes the students of different learning bases from grade one and grade three in Chengcheng middle school,Weinan city as research objects.The students from different class types of grade one are selected to explore the influence of information-based teaching methods on the different levels of classes.The grade three students are chosen to explore the influence of information-based teaching methods on the deepening of students' knowledge and memory.Through comparing specific trigonometric function plate,the article chooses "the image of function y=A sin(cox+?)"in section eight,chapter one of the Beijing normal university version of high school mathematics(Compulsory four)as an typical example,exploring the function of image transformations of y=A sin((?x+?).With the application of modern education technologies to specific teaching cases,the article discusses the influences of information-based teaching methods on students'study of course content in high school math classes.
