The Developmental Trajectory of Middle School Students'Mathematical Problem Solving Ability:A Study Based on Epistemic Network Analysis
Cultivating students'mathematical problem solving ability is one of the important goals of mathematics curriculum and teaching in middle schools.This study adopts epistemic network analysis to explore the development trajectory of middle school students'mathematical problem solving ability,which include the followings:firstly,students should acquire the compe-tencies of problem transformation and problem solving scheme execution;then they will acquire the competency of problem struc-turing in addition to the first two competencies;and finally they will acquire the competency of mathematical problem solving abili-ty in all dimensions,including the competendcy of problem solving scheme formulation.Among them,the competency of problem structuring is the key to promoting the development of students'mathematical problem solving ability from low level to medium level,and the competency of problem solving scheme formulation is the key to promoting the development of their mathematical problem solving ability from medium level to high level.
