Research On Effective Teaching Design Of Function In Junior High School Under New Curriculum Background

Since our country has started the new turn of elementary education curriculum in September,2001, the reform of the elementary education curriculum has been unceasingly deepened. How to develop student's comprehensive qualities through more scientific and effective teaching activities and promote student's all-round progress and development is an urgent issue and challenge that each teacher faces.However, as a result of influence of the long-term traditional teaching idea,and the huge change that occurred to the contemporary students'characteristics,teachers have encountered many difficulties in implementing the new curriculum Among them,how to design teaching process that conforms to the law of development of young people's body and mind is a prominent difficulty. Based on his teaching practice of junior middle school mathematics,the author conducted relevant research on effective teaching design of junior middle school function under the new curriculum background.First, to make teaching more efficient and more effective, this article made a study of the definition of effective teaching and its characteristic and then summarizes the theories related to teaching design,for the purpose of grasping the definition of teaching design ,the flow , its characteristic and theoretical foundation.Next, the article, by means of questionnaire and interview, analyzes the present condition of teaching and learning of function, analyzing students'hindrance and common problems from students'angle on one hand, and looking forward to the ideal teaching approaches from teachers'point of view on the other hand.Then, the article carries a correlation analysis on the links of teaching design of junior middle school function content. This includes:analysis of students'demand,analysis of study content,analysis of students'condition,determination of concrete teaching goal,choice of teaching material,design of teaching strategies,the choice of teaching media, the compilation of appraising plan and so on.Finally,based on above analysis and research and combined with author's teaching practice,the article compiles three cases of junior middle school function teaching design, separately from the three aspects of designing the concept of function teaching design,the principle of function(nature), the teaching design and the function application and teaching design. A correlation analysis is conducted to the case. At the same time,from the perspective of function teaching, several rational proposals have been pointed out as to the teaching of junior middle school function.
