Research On The Teaching Of Power,Exponential And Logarithmic Functions

The function is the foundation of high school mathematics,a main line of high school mathematics,the power function,exponential function,logarithmic function is an important part of function.From the perspective of the new curriculum,mathematics course content requirements for the definition of "wide and shallow",but does not reduce the importance of function module,the power function,exponential function,logarithmic function requirements of bujianfanzeng;from the college entrance examination papers proposition,in the national unified entrance examination and college entrance examination mathematics mathematical proposition proposition papers,involving the function of content,accounting for a large fraction of.However,in the actual teaching process,teachers teach students to reflect,reflect the difficult to learn,especially in power function,exponential function,logarithmic function of three kinds of function,function concept,master the students to understand the nature and use of map drawing examples,there are some difficulties.This paper is based on the students,starting from the students’ cognitive structure,recent developments in the area,with power function,exponential function and logarithmic function in this part as the carrier,a detailed analysis of the power,exponential and logarithmic functions in the process of learning the common fault,then the implementation of specific teaching strategies.The first part of the thesis,combined with the actual high school mathematics education,about power,refers to three kinds of function content,senior high school students’ learning and teachers’ teaching situation of confusion,and a profound understanding to the necessity of this study and the urgency,and then puts forward the overall idea of the article.The second part of the paper,combined with the test volume survey and questionnaire survey,confirmed that the power function,exponential function and logarithmic function learning process students are prone to cognitive errors.The third part of the paper,combined with the test results,analysis of power,index,logarithm function cognitive error causes.Finally,the analysis of the function concept,the comparative teaching,error correction and other aspects of the function of cognitive analysis,and developed a teaching strategy.
