| At present,in our country teachers’ classroom teaching modernization is being reformed gradually.Under such social education environment,it is imperative to vigorously promote the reform of learning-based classroom teaching,which requires teachers of all subjects in the school to pay attention not only to students’ mastery of textbook knowledge,but also to students’ all-around development.The teaching mode of "learning before guidance-problem evaluation" is a new teaching mode which solves preexisting educational puzzles,cooperates with teachers’ positive evaluation in the teaching process,and carries forward the sense of teamwork at the same time.This mode is put forward to meet the advanced education concept and the current national requirements for high school mathematics curriculum standards.Through comprehensive analysis of the current research results on this kind of teaching mode,we know most of them focus on the publicity and promotion at the theoretical level,and there are fewer studies on the application of this model to the actual classroom.On this basis,this paper will deeply discuss how to better combine the teaching mode with the reality of today’s high school mathematics classroom,which is helpful to enrich the theoretical level on the one hand,and has distinct practical value on the other hand.On the basis of referring to a large number of academic materials and combining with the specific standards that students should meet in the Curriculum Standards of High School Mathematics(2017 Edition),this paper investigates the mathematics foundation and learning characteristics of high school students.At the same time,according to the learning theory of constructivism,the teaching research of exponential function,logarithmic function,and graphs and properties of function y=x+(k/x)is carried out for senior one students,and the teaching effect is analyzed and evaluated.This paper also compares the two classes,one of which applies this teaching model,the other doesn’t,so then analyzes the teaching effect of the teaching model of "learning before guidance-problem evaluation".According to the author’s investigation of high school students’ reality of learning mathematics,the author puts forward the corresponding future teaching prospect.This paper adopts the research method combining the questionnaire survey and the comparison method to carry out the teaching practice of applying images and properties of the three kinds of function to the senior one students in the high school investigated by the author.Through the analysis of various data,it can be found that the teaching mode of "learning before guidance-problem evaluation" can,on the premise of realizing students’ mastery of the knowledge taught by teachers,conduct other aspects of learning and research more efficiently,thus increasing the class activity of students in the class.It can be seen that this paper has not only enriched the research results of this teaching model in the concrete practice,but also provided helpful guidance for teachers in front-line teaching,which plays an important role in promoting the overall improvement of the current curriculum education reform. |
