本研究探讨了如何21个大学水平的普通化学的学生，谁收到的指令，强调离子方程的符号水平，解释他们的亚微观层次的理解沉淀反应。学生们通过绘画和半结构化访谈表达的解释揭示了他们所持有的误解的本质。这些误解和教学改革的建议，以目标的误解在这篇文章中进行了检查。
This study examined how 21 college-level general chemistry students, who had received instruction that emphasized the symbolic level of ionic equations, explained their submicroscopic-level understanding of precipitation reactions. Students’ explanations expressed through drawings and semistructured interviews revealed the nature of the misconceptions that they held. These misconceptions and recommendations for instructional changes to target the misconceptions are examined in this article.
