| With the promulgation of the "Full-time Compulsory Education Mathematics Curriculum Standards(Revised Draft)" in 2011,educators at home and abroad have begun to pay widespread attention to problem solving.Nowadays,core literacy has become the center of a new round of curriculum reform,and mathematics teaching should be carried out around this central task.The teaching under the core of mathematics should be open,comprehensive and problem-based.Through the thinking of students,asking questions and making conjectures,they can draw conclusions and improve their ability in the exchange and cooperation between teachers and students or betwen students and students.However,the problem setting in the classroom is not chaotic and optional.The teacher does not simply ask students to solve the problem.Instead,the student is the center.With the suitable problems,the students are guided to take the initiative to ask questions by themselves and participate in the problem.They improve their problem-solving ability in the process of problem solving.In this paper,two classes in grade 5 in a primary school in Xiamen City,is used as the experimental object.Class 6 Grade 5 is selected as experimental classe and Class 5 Grade 5 is used as control classe.Through the questionnaire and a pre-test,we can see the problem-solving ability and core literacy level that students have abtained.On the basis of the analysis of the teaching materials and the recommendations of the internship school team teachers,we constructed a core literacy teaching strategy for the primary school mathematics "problem solving".After four month of teaching in the experimental classe,we can compare and analyze the post-test and pre-test.The research results show that the "problem solving" teaching under the core literacy has certain effects on improving the problem-solving ability of students,and there is a significant effect on students’ mathematical modeling literacy and data analysis literacy improvement.The teaching specific links of "problem solving" in primary school mathematics under core accomplishment include:(i)creating situations,introducing problems(ii)problem embedding,causing thinking(iii)practice Consolidation(iv)classroom summary.The part(ii)can be specifically divided into three links:(1)Problem introduction Knowledge point(2)Problem Inquiry Confusion Point(3)problem looking for growth point.Three links according to this lesson focus on the implementation of core literacy,through the layer of progressive problem setting,guide students to go through the problem solving process,improve problem-solvingability and core literacy level. |
