| Function models can be seen everywhere in life and are widely used.Function plays a pivotal role in junior high school mathematics.Every section has a function.Function runs through junior high school mathematics learning.It is the main content of junior high school mathematics and algebra courses.It contains rich mathematical ideas and methods,which influence This will help students learn and grow in the future.Over the years,it has also been a popular test site for the high school entrance examination.Scores account for a large percentage of the total scores in the high school entrance examination.It requires students to have high abilities in all aspects.The student’s learning function is directly related to the student’s mathematics learning.It has always been a factor for many junior high school students.It is a very headache problem,so how to break through the teaching and learning difficulties of the function has become an urgent problem for teachers and students to solve.Based on a wide range of materials and literature,this paper has formulated a questionnaire on functional learning,divided into teacher and student versions,combined with interviews,using the school’s most recent ACTS test transcript and comparison of the whole district,from knowledge Analyze academic conditions in terms of skills and abilities,combine the above surveys,and formulate function diagnostic questions based on the Chengdu high school entrance examination questions in the past five years,feedback their problems in function learning from the students’ specific problem-solving situations,and find the causes.Based on the statistical analysis of the survey results,the author believes that the typical problems of function learning for junior high school students are mainly divided into learning habits,knowledge,abilities,emotions,and teachers.After deriving the typical problems of student function learning,the author combines my own teaching practice and the experience of excellent front-line teachers around,research operable strategies,and explains from the two levels of teachers and students.The teacher level should pay attention to the cultivation of students’ habits.To achieve,go deep into the essence,pay attention to the concept generation process,strengthen the connection between knowledge and knowledge,pay attention to the setting of life situations,so that mathematics can return to life from life;students should pay attention to every aspect of learning and learn Timely summarize,review,and reflect,learn to classify knowledge,and do a good job of collecting and redoing wrong questions.To provide guidance for my future teaching and help students’ functional learning,and to provide reference for all front-line teachers. |
