A Case Study On The Time Allocation Of First Round Of Basic Review In Senior High School Mathematics

Classroom teaching time is an important teaching resource,and the allocation of classroom teaching time is also a necessary skill for teachers to engage in teaching activities.With the change of the college entrance examination scheme and the current situation of the allocation of time for first round of basic review of senior high school mathematics,it is urgent for us to adjust the allocation of time for first round of basic review of senior high school mathematics.This study takes first round of basic review class of senior high school mathematics teachers in three new four-star high schools in Danyang City as the research object.From the perspectives of teachers and students,the current situation of first round of basic review class of senior high school mathematics is investigated in the form of questionnaires and interviews.The results are as follows:(1)Teachers:1.Teachers have a weak sense of time allocation and lack of reflection.2.Teachers have insufficient abilities in many aspects,which are manifested as inadequate lesson preparation,poor language expression art,single or excessive teaching forms,improper handling of accidents,etc;3.Poor awareness of sharing experience among teachers.(2)Students: 1.Weak awareness of time;2.Lack of goal awareness;3.Distraction.This is the influence of senior high school mathematics first round basic review class time allocation maladjustment of the reason.Six excellent senior high school math teachers were selected to take 48 classroom records of first round of basic review lessons.The average time of the five aspects of topic introduction,knowledge sorting,example explanation,classroom exercises and classroom summary was respectively 1 minute 49 seconds,15 minutes3 seconds,16 minutes 40 seconds,9 minutes 46 seconds and 1 minute 42 seconds.At the same time,the frequency and coverage rate of their classroom questions are also statistically studied.It is tentatively suggested that the time allocation of 5 links in first round of senior high school mathematics basic review class should be controlled in about 2 minutes,15 minutes,16 minutes,10 minutes and 2 minutes.The obtained data should be tracked by the experimental control class,and the correctness of the conclusion should be verified through several test scores and students' return visits.Then I observed and studied a class example of a senior teacher with originality.He broke the traditional basic review class model of 5 links and skillfully generated 7 link models,that is,he added two links of self-examination and classroom self-organization,whose practicality was recognized by most front-line teachers.Based on the time allocation principles of foresight,practicability,prioritization,and developmental principles,combined with the factors that affect the time allocation of first round of basic review of senior high school mathematics,the teacher ' s time allocation concept,lesson preparation,and Teaching methods and questions are put forward,and then suggestions are given for students' time concept,self-control ability and learning motivation.Finally,specific guidance is given on the time allocation of the five links of first round of basic review classes in senior high school mathematics.Teachers and students actively improve their abilities and cooperate with each other to build an efficient basic review classroom.
