An Empirical Research of Cognitive Diagnosis for Two-Dimensional Vector in High School
In order to explore students'potential cognitive structures and improve the current"score-based"dilemma in educational evaluation,we developed and administered a diagnostic test for high school two-dimensional vector knowledge based on cognitive diagnostic assessment(CDA).Quality verification shows that the test has good discrimination and difficulty,the Q matrix and attribute hierarchical relationship are reasonably constructed,and can be used to explore and diagnose high school students'mastery of two-dimensional vector knowledge.The analysis method of cognitive diagnostic technology can provide detailed diagnostic feedback for groups and individuals respectively,and provide corresponding remedial teaching or teaching guidance based on students'actual cognitive structure.Meanwhile,the advanced learning path constructed based on students'ability level and mastery attribute model can provide reference and guidance for teachers'teaching and students'independent learning.
