概念图被认为是一种有效的学习工具，可以帮助学生将新概念整合到现有的知识中。它们也有助于评估学生的学习，并帮助阐明学习发生的地方以及学生持有的无效或不完整的想法。我们已经开发了一个基于网络的概念图建设和基于规则的评价系统，称为概念图工具（CMT），正在部署在大学一级。在学生使用CMT的绘图功能为课程中提出的特定主题构建个人概念图后，他们可以使用基于规则的评估系统对课程教师创建的标准概念图进行评分。学生会得到关于如何改进概念图的即时反馈，他们可以迭代地使用CMT来提高他们对手头主题的理解。基于规则的评估或分级系统部分地在用于概念图的一致评分的手动系统上建模。我们对系统的测试表明，有一个很强的正相关（>0.80）之间的分数的学生的概念图的课程教师评分手动和CMT规则为基础的评价系统。
Concept maps have been heralded as an effective learning tool to help students integrate new concepts into their existing set of knowledge. They are also useful for evaluating student learning and helping to illuminate where learning has occurred and where invalid or incomplete ideas are held by the student. We have developed a web-based concept map construction and rule-based evaluation system called the Concept Mapping Tool (CMT) that is being deployed at the university level. After students use the drawing facility of CMT to construct individual concept maps for a particular topic that was presented in a course, they can then use the rule-based evaluation system to grade their concept maps against a criterion concept map created by the course instructor. Students are given immediate feedback on how to improve their concept maps, and they can use CMT iteratively to improve their understanding of the topic at hand. The rule-based evaluation or grading system is modeled in part on a manual system for the consistent scoring of concept maps. Our tests of the system show that there is a strong positive correlation (>0.80) between the scores on students’ concept maps given by the course instructor grading manually and by the CMT rule-based evaluation system.
