The Teaching Practice Research Of "Quadratic Equation" Exercises Class In Ninth Grade

Equation is an effective model to describe the quantitative relationship in the real world and an important tool for students to establish the relationship between mathematics and life.As an important part of equation model,"Quadratic equation" is crucial for junior high school students to learn its content.Exercise is an important form of mathematical knowledge,and exercise classes are an indispensable part of mathematical teaching.Exercise class teaching can not only consolidate students’ old knowledge,but also strengthen their mathematical thinking,enabling them to gradually master various mathematical thinking methods,and thus comprehensively improve their mathematical core literacy.However,at present,most of the teaching research on the exercise class of Quadratic equation focuses on teaching design or teaching strategy research,which cannot be combined with teaching practice.Therefore,this paper will focus on the teaching practice of the exercise class of "Quadratic equation".Through reading the literature,the research status at home and abroad is sorted out,and the teaching content of Quadratic equation is specifically analyzed.On this basis,by using the methods of questionnaire survey,teacher interview and classroom observation,this paper studies the current teaching situation of the "Quadratic equation" exercise class,and finds the following problems in the exercise class teaching: first,exercise selection depends on teaching aids;Secondly,the teaching content mainly focuses on "question types and answering skills";Thirdly,teaching activities fail to fully consider student subjectivity.In view of the problems found in the current teaching situation,under the guidance of curriculum standards and education and teaching theories,the teaching strategies for optimizing the Ninth grade "Quadratic equation" exercise class are proposed from four aspects: the selection before exercise class,the explanation in exercise class,the cultivation of exercise solution methods,and the evaluation and feedback of exercise class.Based on this strategy,the teaching practice of the exercise class of "Quadratic equation" was carried out.Through practice,it was found that students in the experimental class showed a significant increase in interest in learning exercises,and the classroom atmosphere became more active.Therefore,the teaching strategy of "Quadratic equation" exercise class proposed in this study is feasible and effective for students to "learn".
