Research On Teaching Design Of Problem Chain Based On Mathematics Core Literacy

With the continuous change of times and the multi-dimensional development of society,the general environment puts forward a new definition of talents and requires more dimensions of talents' ability.High school mathematics is a compulsory course in high school,and the concept of mathematics core literacy is put forward in the curriculum standard.Question chain teaching is a teaching method in which students construct their own framework for a certain knowledge in the process of asking questions,obtaining answers and discussing with teachers.According to the current domestic education situation and the practice of mathematics classroom teaching in senior high school,this paper proposes to study the teaching design of problem chain based on mathematics core literacy,so as to meet the quantitative teaching indicators and strive to achieve the goal of cultivating students' mathematics core literacy.Firstly,this paper analyzes the contents and corresponding levels of the six core mathematical literacy,and finds that the high-level levels of the six core literacy put forward requirements for students to identify and abstract mathematical problems in various complex and comprehensive situations.Based on the above analysis,this paper puts forward that the teaching design of problem chain based on mathematics core literacy should follow the integrity and relevance,hierarchy and development,situationality and mobility,then explains it.Then,it puts forward four strategies that can be applied in the teaching design of problem chain based on mathematics core literacy: situational introduced strategy,core clarified strategy,induction and summary strategy,and using promotion strategy.Based on the above research results,the general process of problem chain teaching design based on mathematical core literacy is given.Then,using the general process proposed in the third chapter,combining with the principles and strategies designed,taking the derivation and application of the general term formula of the equal ratio series as the teaching material content,and taking the achievement of knowledge,skills and the cultivation of mathematics core literacy as the teaching goal,four main problem chains are designed: situation introduction problem chain,core problem chain,induction and summary problem chain and application and promotion problem chain.Finally,the paper puts the design results into the teaching experiment,observes the students' classroom response,and conducts the pre and post exercise tests on them.After analyzing the experimental results,it is found that the application of the problem chain teaching method based on mathematics core literacy is helpful to increase students' classroom participation,achieve teaching objectives and improve test scores...
