This dimension focuses on the “syntactic structures” of knowledge,that is the understanding of knowledge.Researchers of Harvard argue that students' understanding of knowledge should include understanding of methods.According to application of research methods,students may question the statements or construct new knowledge.This viewpoint gives us inspirations about evaluation.In recent year,this kind of questions appear in the exams in China.For example:three students inquire which can shield the remote signal best using paper,plastic film and cotton cloth at home.Student A does this experiment at his home.He put several pieces of paper between the remote and TV,operates the remote and if it still can influence the TV,increases the number of pieces of paper until the remote can't control the TV.He mark down the number of the paper— 14 pieces.Student B does the same experiment but use plastic film at her home.She mark down the number of the plastic film—20 pieces .Student C does the same experiment but use cotton cloth at his home.He mark down the number of the cotton cloth— 10 pieces.They draw the conclusion:cotton cloth can shield the remote signal most effectively among paper,plastic film and cotton cloth.The inquiry questions are:
