C与S构图评估技术的比较研究

The Comparison Between C and S CMap Assessment Techniques

引用Yue等学者关于2种概念图——自由构图与选择构图(简称C与S)评估技术等价性的实验研究,用总正确得分、单命题得分、命题选择和结构复杂性4个变量,以《量子力学》为载体对C与S技术进行了定性和定量的比较研究.实验结果显示,2种构建概念图技术的效果不同,|Z|=1.98,P<0.05,因此,C技术比S技术更能捕捉学生构建知识结构的情况,而S技术在构图的制作上易于C技术;就评价工具而言,C技术更适于形成性评估,而S技术较适于终结性评估.构图结果表明,当今大学生在知识组织、知识构建、知识表征特别是知识创新方面有待提高.

According to the equivalence study of two concept-map assessment techniques（C technique and S technique） made by Yue Yin,Jim Vanides and Maria Araceli Ruiz-Primo. By using quantum mechanics, both their products are compared quantitatively and qualitatively as to total accuracy score, individual proposition scores, proposition choice, map structure complexity. The conclution is the two mapping techniques are not equivalent： ｜ Z｜ = 1.98, P 〈 0.05, C technique is better than S technique in capturing students＇ partial knowledge, even though S can be scored more efficiently than C. Based on their characteristics,if used as an assessment tool, C technique is more suitable for formative assessment while S technique is more fit for large scale assessments. The results indicates that the colleges need improving in knowledge organization, knowledge construction and knowledge representative, especially in knowledge innovation.
