摘要： The study presented here is a follow-up to a previous report in which we investigated how general-chemistry students in a transformed curriculum reason about simple acid base reactions. In the present study, we use and adapt the previously developed coding scheme for a longitudinal study in which we follow students from general chemistry through organic chemistry. We find that (i) generally, the manner in which students reason about acid base reactions increases in sophistication over the course of a two-semester sequence of organic chemistry;(ii) there is little difference in reasoning between students at the end of a transformed general-chemistry course and a similar cohort at the beginning of organic chemistry;(iii) the nature of a student's general-chemistry experience has a profound effect on the sophistication of their reasoning in that students from a transformed general-chemistry course are more likely to provide causal mechanistic explanations for simple acid base reactions than students with other general-chemistry experiences;and (iv) the type of acid base reaction that the students discuss impacts the type of reasoning they exhibit. We find that when asked to explain a Lewis acid base reaction, students are less likely to invoke electrostatic ideas.

摘要： 在高中阶段的实践性科目中,化学占据了重要的位置,它贯穿了我们高中三年的学习生活。经历了初中阶段的奠基,高中阶段的化学学习将会步入一个新的高度。无论是学习的深度,还是难度,都会有所上升。尤其在高中阶段,无机化学让位,有机化学成为学习的重点。在学习时掌握正确的方法,提升自己的效率,对于我们高中生来说有一定难度。所以,找到有机化学在掌握时的诀窍,是我们探讨的重中之重。
