在评估中使用学生构建的概念图与国家科学教育标准规定的重点变化是一致的。权威人士对概念图评分系统及其相关的有效性和可靠性表示担忧。他们青睐的方法，采用专家/标准地图作为参考，并强调使用准确的概念关系，在推导出的分数，这已被发现与标准化考试的表现。在这项研究中，学生构建的概念图（n= 17），出现了从教学后的采访有关氯氟烃的老师，专家地图使用的关系加权方案进行了评分。评分方案的评分者间可靠性较高（r= 0.959）。学生的地图得分与他们在加州成就测试中的得分高度相关（r= 0.729），与他们的探路者指数中度相关（r= 0.474），后者被认为是结构知识的一个很好的衡量标准。修正后的地图分数，仅来自于包含一个或多个概念的关系中采用的探路者分析，是一个有统计学意义（p= 0.031）的探路者指数的预测。这项研究的结果支持了其他人的建议，使用专家参考，并强调概念图评估的概念关系。
The use of student-constructed concept maps in assessment is congruent with the changing emphases set forth by the National Science Education Standards. Authorities have expressed concern about concept map scoring systems and their associated validity and reliability. They favor methods that employ expert/criterion maps as referents and emphasize the use of accurate concept relationships in deriving scores, which have been found to correlate with performance on standardized tests. In this study, student constructed concept maps (n= 17) that emerged from post-instructional interviews about chlorofluorocarbons were scored against a teacher-expert map using a scheme weighted for relationships. Interrater reliability for the scoring scheme was high (r= .959). Students' map scores correlated highly with their scores on the California Achievement Test component total (r= .729) and moderately with their Pathfinder index (r= .474), the latter believed to be an excellent measure of structural knowledge. A revised map score, derived only from relationships containing one or more of the concepts employed in Pathfinder analysis, was a statistically significant (p= .031) predictor of the Pathfinder index. The findings of this study support the recommendations of others to use expert referents and emphasize concept relationships in assessing concept maps.
