The Teaching Study On The Exercise Lesson Of Multiplication And Division Of Integral Expressions In Grade 7

This paper takes the seventh grade students of DaYang middle school to learn "the multiplication and division of integral form" as an example,and mainly studies the following contents: select the seventh grade students of DaYang middle school to carry out a questionnaire survey,and statistical survey data,and analyze the existing problems;Combined with the practice of DaYang middle school,the causes of the problems are analyzed from the aspects of knowledge itself,students and teachers.Aiming at the concrete problems in the recitation class of DaYang middle school,this paper puts forward the concrete teaching strategies.The significance of this study is to,through the sun middle school grade seven students "," integral expression of the investigation of the status of the recitation,and to find the sun middle school grade seven students in the " integral expression," the problems existing in the recitation,and cause problems based on the discussion,on the one hand,for the sun middle school grade seven students to learn the part to provide effective methods,provide effective teaching strategy for teachers,so as to improve the teaching quality of sun middle school.On the other hand,students can realize the necessity and practicality of learning "multiplication and division of integral form" and stimulate their interest in learning mathematics.In addition,the research results of this paper can also provide experience for the majority of front-line teachers in similar schools.The research conclusion of this paper is that the survey found that the problems of recitation class are: students' lack of interest in "integral multiplication and division" and lack of good learning habits,students will not use the algorithm,classroom explanation is too much lack of interaction,the teacher lectures "one size does not fit all".Combined with the practice of DaYang middle school,this paper analyzes the causes of the problems from the aspects of knowledge itself,students and teachers.The reason of "multiplication and division of integral form" knowledge itself is trivial and computationally strong;The reasons of students are poor foundation of mathematics and lack of confidence in learning.There are some reasons for teachers to ignore the individual differences of students and the teaching methods of teachers need to be improved.Specific teaching strategies are proposed: teachers should select typical exercises,pay attention to the inspiration,pertinence,diversity and flexibility of exercises,and pay attention to lesson preparation;Integration of knowledge points to simplify the complex;Lay a solid foundation for students and cultivate their self-confidence;Select teaching methods to improve teaching effects,such as creating situations,summarizing problems,skillfully guiding,variable teaching,etc.Make full use of after-class time to expand classroom capacity;The teacher carries on the teaching reflection positively after the exercise class,summarizes the experience and the insufficiency unceasingly;Cultivate good math learning habits of students,such as the habit of taking notes in recitation class,recitation after class review habits.The research methods of this paper mainly include literature research,questionnaire survey and statistics.
