A Study On Secondary Function Teaching Based On "Introduction To Academic Cases"

The function is the foundation of modern mathematics and is the most important and complex content in middle school mathematics.It runs through the entire mathematical learning process.Due to the richness of function content,the foundation of knowledge,the universality of application,and the inclusion of mathematical ideas,it has become the core content of middle school mathematics,providing a wide range of application space and methodological significance for the study of other branches of mathematics.Therefore,some scholars have studied the teaching of quadratic functions from different aspects.I combined four years of ninth grade teaching work and found that every time I taught a quadratic function,the teacher was exhausted and the students were still left behind.Students do not have a good grasp of the image and properties of quadratic functions for the concept of quadratic functions,and it is even more difficult to do a quadratic function comprehensive problem.From the actual teaching effect,students to the quadratic function part of the knowledge of the situation are not optimistic.On this basis,in order to adapt to the current new teaching methods,I have studied the teaching of quadratic functions based on the "introduction of studies".By consulting a large number of documents and materials,I combined the research conclusions of the majority of educational scholars.Some old teachers with rich teaching experience in consulting schools used questionnaires and test papers to investigate the students' understanding and mastery of quadratic functions,and also investigated the students' views and suggestions on the current teaching methods.According to the results of the survey,This paper makes an analysis of the reasons for the learning difficulties of students and the promotion of the study of quadratic function teaching.Finally,from the concept of quadratic function,the image and nature of quadratic function,the application of quadratic function three aspects of teaching research,the design of the corresponding design of the corresponding teaching strategy,the demonstration of the case.Put forward: connecting with life,seize students 'interest in learning;Analogous primary function to realize knowledge transfer;Pay attention to the drawing process and strengthen the knowledge base;Throughnumerical deformation,deepen the understanding of nature;Transform the inherent thinking mode and penetrate the combination of numbers and forms;Problem classification,effective decomposition of difficulties;The problem is stratified to help students clear their minds;Using hands-on operation,multimedia display and other teaching AIDS and other teaching countermeasures.To help students to construct the contents of quadratic function autonomously by using the instruction of the program.Cultivate students 'ability of observation and induction;Strengthen students 'basic drawing and computing ability and standardize the problem solving process so as to improve the teaching effect.Hope that through this paper,to the majority of mathematics teachers to provide a reference.
