The Design And Practice Of Algebra Study In Junior High School

Basically,every knowledge point in the math class can be explained by mathematics exercises,also can be improved and consolidated,the form "exercise" shows in the whole teaching procedure.So it is the reason that the importance for the junior middle school teacher is the design of the exercise.Especially in some remote mountain area,the quality of students general lower than which in cities,and they have little interest in study.what can improve current situation is to design exercises which is suitable for the students.The research use the method is case study method.For example,in the Nine-year compulsory education mathematics textbook,under the eighth grade,chapter 18,first period,<parallelogram>,my objects of study is two classes of students who were taught by a researcher of junior middle school in towns,to carry out the research through the procedure of the design how to teach parallelogram.In order to achieve the research,I put forward the question:what is the principle of the design of mathematic exercises?Through the implementation plan and introspection,I draw a conclusion just as follows:the design of mathematic exercise needs to follow the objective,scientific,harmonious and beautiful principles.Usually,the method of the design of mathematic exercises conclude deductive method,base quantity method,inverse method,condition of transformation method,analogy and promotion method,historical evolution method and model method.Finally,according the conclusion of the research,I come up with some suggestions:1.Teachers should comprehend and grasp the knowledge of mathematic correctly,pay attention to the easily wrong point and the difficulty in daily study.By the way,they also should spend more time listening class,remarking,and communicating with experienced teachers.2.The design of mathematic exercise need to rethink and perfect continuously,so it is importance to develop a rethink habit for teachers.
