In this study, a set of hybrid images was designed as a new and up‐to‐date unexamined type of external visual representations in the chemistry classroom. One challenging teaching theme was chosen (“Amino acids and proteins”), and the hybrid images were used among novices—primary school students. For the purpose of the study, two groups were formed: experimental and control. The experimental group was taught using the hybrid images, while the control group was subjected to a traditional approach. After conducting the experiment, no statistically significant difference in the average performances between the two groups was found. However, the experimental group outperformed the control group in several test items. Additionally, misconceptions appeared within the C group. The results showed that several hybrid images with a potentially good methodological design might help students to develop conceptual understanding of some important concepts of amino acids and proteins (e.g., formation of peptide bonds). © 2019 International Union of Biochemistry and Molecular Biology, 47(6):644–655, 2019.

混合图像作为小学化学课教学的一部分：掌握氨基酸和蛋白质的概念

在这项研究中，一组混合图像被设计为化学课堂中一种新的和最新的未经审查的外部视觉表示。选择了一个具有挑战性的教学主题（“氨基酸和蛋白质”），混合图像用于新手——小学生。为了研究的目的，形成了两组：实验组和对照组。实验组使用混合图像进行教学，而对照组则采用传统方法。进行实验后，发现两组之间的平均表现没有统计学上的显着差异。然而，实验组在几个测试项目上的表现优于对照组。此外，C 组内部出现了误解。结果表明，具有潜在良好方法设计的几个混合图像可能有助于学生对氨基酸和蛋白质的一些重要概念（例如，肽键的形成）进行概念性理解。© 2019 国际生物化学与分子生物学联盟，47(6):644–655，2019。
