Research On Effectiveness Design Of Lead-in To Mathematics Class In Junior High School

In recent years,under the guidance of the concept of new curriculum reform,more and more teachers begin to pay attention to lead-in.In the process of mathematics teaching in junior high school,teaching lead-in,which is the first part,plays an important role of leading to the key point.Adopting appropriate ways to conduct lead-in can not only help students settle down and quickly enter the state of preparation,but can also attract students' attention to make them clear of the learning direction and tasks of this math lesson,and effectively to stimulate students' desire for knowledge.At the same time,it is also the emotional bond for teachers and students to interact to realize good communication.Based on the important role and practical significance of lead-in in mathematics teaching,this paper carries out a research on the strategies of lead-in in junior high school mathematics from the two aspects of relevant theories and teaching practice.The content of this paper can be divided into four sections,which respectively,are the relevant concept definition and theoretical basis,the analysis of the existing problems and the improvement of the existing problems in the lead-in of mathematics class in junior high school,the validity of the lead-in of mathematics class in junior high school and the design of the lead-in of mathematics class in junior high school.In the research of this topic,the author mainly adopts the literature method,the educational experiment method,the questionnaire method and the observation method.On the basis of consulting many domestic and foreign related literature,the author has a deep understanding of the research status of this topic.Through a large number of observation of mathematics classroom teaching,combined with their own teaching practice experience,the author found the common problems and causes of mathematics lead-in in current junior high school,and put forward feasible improvement strategies.Then we carry out the mathematics class teaching experiment,and draw the corresponding conclusion by analyzing the data,which provides the factual basis of proving the effectiveness of the improvement strategies.Through sorting and integration,the principles of junior high school mathematics teaching lead-in are summarized.Finally,on the basis of following the principle of lead-in,the author further develops the lead-in design for different types of math courses.The innovation of this study lies in the junior high school mathematics class import and comprehensive exploration of the system,from finding problems to put forward the improvement strategies,to test the effectiveness of the strategy,the last arrival to class import effectiveness design,for example,not only enrich the theory of mathematics class import,also for the import of first-line teachers design provides reference.The teacher in the lead-in design should also avoid a single form lead-in,lead-in content deviating from the teaching objectives,long-time lead-in,neglect of the main status of students and other problems.The lead-in of junior high school mathematics class should be carefully designed on the basis of following the principles of systematicness,purpose,inspiration,interestingness,participation and capacity,so as to ensure the importance of the lead-in in the class effectively.Only by following the law of students' cognition,taking students as the main body of teaching,accurately grasping the teaching objectives,effectively integrating educational resources,and overall planning of teaching activities,can we actively carry out teaching interaction and realize teaching benefits between teachers and students.
