Teaching Research About Function Concept Of High School Based On Information Technology

With the continuous deepening of basic education curriculum reform and the acceleration of educational information informatization,mathematics teaching has been gradually overwhelmed by information technology.Giving full play to the role of information technology in improving students' mathematical literacy,and exploring ways to integrate information technology into curriculum teaching become important research questions.Function concept is the core concept of high school mathematics.Function idea act as an important way of thinking in high school mathematics.It is of great significance to master function idea for students' problem-solving.The present thesis makes an investigation of information technology on function concept teaching,and problem-solving teaching with function idea.By using the method of literature research,investigation and case study,The study can draw the following conclusion:Firstly,students are not fully aware of the importance of the function and is not enough understand the history of the development of the function and is not clear about the characteristics of the study object and the relationship with the movement of the understanding of the relationship.Secondly,teachers do not understand the role of information technology in the basic characteristics of performance functions,the ability to cultivate students' abstract generalization,and the ability to use functions to solve problem problems.The use of information technology basically stay in the demonstration and display and so on.Thirdly,advanced teaching philosophy may not occur with advanced information technology.So the teaching idea of teacher should keep pace with the times.The advantages of information technology needs to be valued by teachers according to modern teaching theory,mush importance should be attached to the improvement of students' comprehensive competence while we are paying attention to students' scores.Last but not least,function is considered as one of the most difficult knowledge point by students.The instruction integrated information teaching visually shows the relationship among variables,which makes abstract concepts into concrete images and further make static for dynamic.On the one hand,it helps students grasp the essence of function and find out the constant rules in the process of motion change,which contributes to students' understanding of function idea.On the other hand,the understanding of knowledge is strengthen competence.Students' function concept can be consolidated by information technology aided function idea.Furthermore,it ishelpful to promote students' understanding of function idea and reserve their problem-solving ability for the following learning.
