Research On Optimization Strategy And Application Of New Knowledge Micro Courses In Junior Middle School Mathematics Based On Zhang Jingzhong’s Educational Mathematics Thought

The education informatization 2.0 action plan issued by the Ministry of education in2018 clearly pointed out the problem of "insufficient development and service capacity of digital education resources and insufficient in-depth integration of information technology and subject teaching".As a digital resource,micro class can give full play to the potential of information technology and improve teachers’ teaching methods,which has become an important topic of information technology integration teaching research.However,the research shows that there are some prominent problems in the design of new micro courses in mathematics,such as emphasizing experience rather than theoretical guidance,emphasizing form rather than content.Therefore,exploring the optimization strategy of micro courses has strong theoretical value.Under the background of the "double reduction" policy,mathematics teachers urgently seek new ways to promote the high efficiency and high quality of teaching and learning.Academician Zhang Jingzhong’s educational mathematics thought aims to make mathematics easier,transform the difficult points of mathematics,reduce the difficulty,and make it more suitable for teachers’ teaching and learning,which is in line with the requirements of the development of the times.Therefore,the implementation of educational mathematics thought in mathematics teaching has high practical significance.Based on the above thinking,the author will focus on the optimization strategy and application of new knowledge micro courses in junior middle school mathematics based on Zhang Jingzhong’s educational mathematics.The following research questions are put forward:（1）how to optimize the new knowledge micro course of mathematics based on the idea of educational mathematics?（2）What is the teaching effect of optimizing the new knowledge micro course?In theory,based on academician Zhang Jingzhong’s educational mathematics thought,combined with the teaching concept of multiple representation theory and the trinity of fish and fishing desire,this paper discusses the optimization strategy of new knowledge micro courses in mathematics,that is,design optimization strategy,interface optimization strategy and recording optimization strategy.Among them,the design strategies include:enhancing interest and stimulating learning desire;Understand the diversity and highlight the essential connection;Diversity of activities to improve mathematical literacy.The principles of optimizing interface are: information packaging principle,space proximity principle,time proximity principle,consistency principle and dual channel principle.The interface optimization strategies are: context presentation strategy,clue pointing strategy,dynamic and static combination strategy,graphic structure strategy.Optimize the recording strategy: highlight the "speaking" point-inspiration and guidance strategy;Identify the "look" point-visual impact;Cut into the "listening" point-auxiliary experience.
