Investigation And Strategy Research On Expansion Mathematics Curriculum Teaching Of Junior Middle School

The junior high school expansion mathematics curriculum is an extension and supplement of the mathematics basic curriculum teaching.The scientifically-planned and ra tionally-designed expansion mathematics curriculum can effectively broaden students' subject horizons,develop students' interest in mathematics,and fully develo-p st udents' core literacy.According to the survey,the current expansion mathematics curriculum can be guaranteed in some regions.However,it is difficult to break away from the shackles of the exam in the specific design and implementation of the curric-ulum,and it is impossible to implement the purpose of the expansion curriculum,and it is even unable to design and implement closely which focus on the core literacy of the students.Therefore,the research direction of this paper is focused on the investigation and strat egy research of junior high school expansion mathematics curriculum teaching.Through the questionnaire survey,we understand and analyze the design and implem-enta tion of expansion mathematics curriculum in 7 junior high schools in Hangzhou.Based on this,combined with the literature analysis method,this paper proposes a de-sign strategy for expansion mathematics curriculum under the guidance of core literacy.The study initially obtained the following conclusions:1.The junior high school mathematics expansion curriculum should focus on the core literacy: knowledge learning,problem solving,exchange and cooperation,mathematical thinking and mathematical spirit.2.Current status of implementation of junior high school mathematics expansion curriculum: Teachers are very confused about how mathematics expansion curriculum are designed and implemented;Course content arrangements fail to take into account academic conditions;The goal design of the curriculum focuses more on basic knowledge and basic skills;Lack of learning resources and evaluation The mechanism is not perfect and there is no evaluation standard for mathematics development classes.3.The design strategy of the mathematics development curriculum based on core literacy was proposed: starting from the design process,the theory and case studies of pre-analysis,problem design,and activity process arrangement were carried out.
