Practical Research On The Teaching Activities Of Mathematics "problems" For Junior High School Students

The Mathematics Curriculum Standards for Full-time Compulsory Education(Experimental Draft),published in 2001,emphasizes that improving students' mathematical literacy is the aim of mathematics curriculum in junior middle school education.The curriculum standards require that students' mathematical thinking ability be trained,their mathematical language expression ability be emphasized,and their ability to solve mathematical problems be improved.Today's junior high school mathematics classroom is still more traditional teaching methods,teachers are the protagonists in class,habits in the classroom,students rarely have the opportunity to actively explore mathematical knowledge,students' learning effect is not good.Many students often feel that the exercises to solve are familiar,but there is still no way to solve the problem.How to cultivate students' mathematical thinking ability and improve their ability to solve mathematical problems is an urgent problem in current mathematics education.Based on the current situation of junior middle school mathematics classroom,in order to cultivate students' mathematical thinking ability and improve their ability to solve mathematical problems,the author combines his own learning and teaching experience to think about this problem: can students' "problem-explanation" activities be integrated into junior middle school mathematics teaching activities,put forward operational student "problem-explanation" activities process and mode,and according to these activities Flow and pattern design students' teaching activities of "problem-solving".In the teaching activities of "problem-solving",gradually cultivate students' mathematical thinking ability and improve their ability to solve mathematical problems?In order to study this problem,the author first combs the relevant literature and puts forward the principles of junior high school students' mathematics "problem-solving" teaching activities,including the principle of teacher-student participation,the principle of pre-plan,the teaching principle in accordance with aptitude of them and the principle of pleasure.It points out that the content ofstudents' "problem-explanation" is students' examination,thinking,expansion and Reflection on exercises under the guidance of teachers.According to the principle and content of problem-solving,this paper puts forward the process and mode of student's teaching activity of "problem-solving",designs and implements student's teaching activity of "problem-solving".This paper makes an empirical analysis on the effect of students' teaching activities of "problem-solving" by means of experiments.By setting up an experimental class and a control class,using pre-test and post-test,it examines the changes of students' understanding of mathematics learning and their ability to solve mathematical problems by means of questionnaires and mathematical examinations.The results of the experiment show that the students' problem-solving teaching activities have indeed improved their ability to solve mathematical problems,enhanced their interest in learning mathematics,and promoted the exchange of mathematical problems between teachers and students,students and students.In designing the teaching activities of "problem-explanation",there are also some points needing attention,including students' "problem-explanation" can not blindly pursue high difficulty,teachers should pay attention to the control and guidance of the process of problem-explanation,etc.
