A Case Study Of "Integrated And Practical"Teaching Design For Junior Middle School Mathematics

With the deepening and development of the new curriculum standards,more and more people begin to study the contents of the field of mathematics synthesis and practice in junior high school.Through the study of relevant theoretical knowledge and the reference of existing experience,the author analyzed and studied different types of junior middle school mathematics comprehensive and practical teaching design cases,and kept exploring,reflecting and summarizing the main results as follows:(1)After analyzing the research status of the synthesis and practice of junior high school mathematics at home and abroad,this paper expounds the meaning,characteristics and educational value of the synthesis and practice of junior high school mathematics.Its characteristics are: synthesis and innovation,independence and exploration,generation and openness,and process and practice.Based on Dewey's "learning by doing" education theory and constructivism learning theory,Piaget's activity teaching theory and Bruner's "discovery teaching method" as the practical guide,we should carry out the effective teaching of mathematics synthesis and practice in junior middle school.(2)Analyzing the teaching contents of junior high school mathematics synthesis and practice from three aspects: the teaching requirements of the new curriculum standards on junior high school mathematics synthesis and practice,the presentation of junior high school mathematics synthesis and practice in the junior high school mathematics textbook published by the People's Education Press,and the classification of the class types of junior high school mathematics synthesis and practice.It also puts forward that the teaching design of synthesis and practice should follow five basic principles,such as reality,openness,inquiry,feasibility and consolidation.(3)On the basis of the previous theory,refer to the relevant literature research,gives the junior high school mathematics integrated and practical teaching design process,including three modules: one is to choose and determine the theme;Second,the design and development of comprehensive and practical teaching;The third is the implementation and evaluation of comprehensive and practical teaching.And put forward the "question to stimulate interest,hands-on practice,cooperation and communication,practice and exploration,expand the application" as the main line of teaching strategies.(4)According to the related theory basis to the junior middle school mathematics comprehensive and practical part as an example,design a "hands-on classes--to 'use of goniometer measurement object height" and "mathematical modeling classes--with the application of the quadratic function,for example","law of probing into the regular class-with'the graphics changes to explore and express" and other three types of teaching design.And from the teaching content,goal and goal analysis,teaching model,teaching process design and analysis,goal design and detection,teaching reflection and other aspects of analysis and research,are equipped with relevant analysis instructions,to explore different types of comprehensive and practical course effective teaching mode.Different types of comprehensive and practical courses,teaching design process and teaching mode are also different.But this paper only to junior high school mathematics synthesis and practice of the "mathematical activity" section of the three teaching cases for in-depth research and analysis,the teaching model is not perfect,not comprehensive.At the same time the paper is not comprehensive and practice of junior middle school mathematics of other content such as "project learning","experiment and explore","information technology" and so on the in-depth research,so we will continue to strengthen the comprehensive study of teaching content and practice of each plate,design develop excellent comprehensive and practice of junior middle school mathematics teaching case,Exploring and practicing reasonable teaching process and effective teaching mode is an aspect that needs further thinking and research in the future.
