| Exercise is an important manifestation of mathematical knowledge,and exercise class is an important class type in mathematics teaching.Both of them play a very important role in students' mathematics learning and play a great role in improving students' mathematics achievement.However,there are still many problems in today's senior high school mathematics exercise class teaching,which leads to low teaching efficiency,is not conducive to the cultivation of students' skills,abilities and mathematical literacy,and cannot play the real role of exercise class.Based on this,this paper uses literature analysis,questionnaire survey and other research methods,and combined with their own practical experience,in-depth into the high school mathematics classroom to study the following two issues.On the one hand,it is an inquiry into the reasons for the low teaching efficiency of high school mathematics exercise classes.On the other hand,it is how to design the teaching of high school mathematics exercise classes in order to play its real role.The following conclusions are drawn from the research:(1)In this paper,exercise classes are divided into four categories,namely,new exercises,pure exercises,assessment exercises,comprehensive application exercises.According to different types of exercise class teachers should carry out different teaching design,including updating the teaching objectives and teaching focus of exercise class.(2)Teachers should make adequate preparations before preparing lessons,including not only carefully studying the contents of teaching materials and curriculum standards,but also thoroughly understanding the learning and psychological conditions of the students taught,and if necessary,guiding them,while scientifically designing teaching links,paying attention to the guidance of students' values,and sparing no effort to promote the healthy development of students' comprehensive quality in all aspects.(3)exercise choice to pay attention to the following points,the quantity of questions should be moderate and representative;the question type should be targeted and hierarchical,and should have ductility;the reasonable application of problem variants and open questions,if conditions permit,we can try to make up the questions independently.(4)in classroom teaching,teachers should pay attention to the role played by teachers,and students' independent learning should be emphasized.Through a series of teaching links such as classroom teachers' questions and the communication between students and students,students should be inspired and induced to keep up with the teaching progress,and more importantly,students should pay attention to teaching according to their aptitude.(5)Teachers should carry on the teaching reflection in time,carry on the objective and scientific analysis to the teaching,control their own teaching mode and teaching method,and constantly improve their teaching ability and teaching efficiency. |
