对物质的颗粒性(PNM)的概念理解已被证明是学习化学成功的关键。在这项研究中，使用了一种新开发的工具，称为颗粒物性质评估(ParNoMA)作为前测和后测，以衡量学生对PNM关于物质阶段和相变的概念性理解。本研究调查了分子水平水的动画对从中学到大学的学生纠正PNM误解的能力，并对男女学生的结果进行了比较。数据表明，分子水平的动画帮助学生提高了他们在ParNoMA上的分数。男生的前测成绩显著高于女生；观看动画的男生和女生的后测成绩相当。观看动画似乎提高了女学生的后测成绩，缩小了国际考试前存在的性别差距。
Conceptual understanding of the particulate nature of matter (PNM) has been shown to be critical for success in learning chemistry. In this study, a newly developed instrument called the Particulate Nature of Matter Assessment (ParNoMA) was used as a pretest and posttest to measure students' conceptual understanding of the PNM regarding phases of matter and phase changes. The capacity of animations of molecular-level water to remediate PNM misconceptions held by students from middle school through college was investigated and the results of male and female students were compared. The data indicate that molecular-level animations helped students to improve their scores on the ParNoMA. Pretest scores for male students were significantly higher than those for female students; the posttest scores for the students who viewed the animations were equivalent for males and females. Watching the animations seemed to improve the posttest scores of female students, closing the gender gap that existed prior to the int...
