A Study On The Influence Of Different Introduction Methods On The Learning Quality Of Mathematics Concepts Of Junior High School Student

Mathematical concept is the basic unit of mathematics,mathematics concept teaching is one of the focus of the mathematics teaching,the introduction of the concept as the first step in the concept teaching,the introduction of concepts in a different way,makes the student to the understanding of the concept of deviation,affecting the quality of classroom teaching,even influence the mathematics view,so choose the right means of concept is introduced,It is the key point of concept teaching to let students immerse themselves in the process of concept learning and correctly understand mathematical concepts.The main research questions are as follows :(1)are there significant differences in the impact of three concept introduction methods on the quality of students' concept learning?(2)Are there significant differences in the impact of the three concept introduction methods on the concept learning quality of students of different genders,students of different academic levels and students of different learning strategies?Around the research problem,the first step is literature analysis.Refer to relevant literature according to research problems and research needs,so as to determine follow-up research ideas and research tools,and make full preparations for the research;The second step adopts expert consultation method and content analysis method.According to the tangent line of the circle,the teaching design,post-test questions and interview outline of different introduction methods are designed by combining the teaching materials,literature and the modification opinions of frontline teachers and experts.The third step is to adopt the experimental method and questionnaire method.Respectively introduced in different mode to carry out the teaching of three class,one class based on academic view approach to teaching,introduced definition of problem situation,takes over the definition based on academic view of 2 class teaching in the form of review introduced 3 class based on the teaching material view definition of hands-on approach to teaching are introduced,the three class test after test and questionnaire survey;The fourth step is interview analysis.After the teaching,one student was selected from the high group,the middle group and the low group to interview,and the junior high school students' learning strategy scale prepared by Wang Guangming et al.was used to conduct a questionnaire survey.The fifth step is data analysis.Statistical software SPSS 22.0 was used to analyze the data and determine the significant impact of different introduction methods of circle tangents on students' concept learning quality.Conclusion :(1)there are significant differences in the quality of concept learning between the three teaching methods of introducing circle tangent line.Among them,only the introduction of problem situation and the introduction of hands-on operation,the introduction of review and the introduction of hands-on operation can produce significant and moderate differences in the quality of students' concept learning.(2)There was no significant difference in the concept learning quality of students of different genders in the three teaching methods of the tangent line of the circle;(3)There is a significant difference in the concept learning quality of students with different academic levels.Among them,the three introduction teaching methods only have significant difference in the quality of concept learning between high group and intermediate group,and the difference effect is large;(4)There are significant differences in the concept learning quality of students with different learning strategies.Among them,using different introduction methods only has a significant difference in the concept learning quality of students with medium and low learning strategies,and the effect is large.Teaching suggestions include :(1)innovate the way of introducing concepts to stimulate students' interest in learning;(2)Introduce concepts into hands-on operation to cultivate students' hands-on ability;(3)Pay attention to the creation of problem situation,closely related to students' life;(3)Strengthen the cultivation of learning strategies and establish good learning habits.
