Abstract
Interpreting three-dimensional models of biological macromolecules is a key skill in biochemistry, closely tied to students' visuospatial abilities. As students interact with these models and explain biochemical concepts, they often use gesture to complement verbal descriptions. Here, we utilize an embodied cognition-based approach to characterize undergraduate students' gesture production as they described and interpreted an augmented reality (AR) model of potassium channel structure and function. Our analysis uncovered two emergent patterns of gesture production employed by students, as well as common sets of gestures linked across categories of biochemistry content. Additionally, we present three cases that highlight changes in gesture production following interaction with a 3D AR visualization. Together, these observations highlight the importance of attending to gesture in learner-centered pedagogies in undergraduate biochemistry education.
解读生物大分子的三维模型是生物化学的一项关键技能，与学生的视觉空间能力密切相关。当学生与这些模型互动并解释生化概念时，他们经常使用手势来补充语言描述。在这里，我们利用一种基于具身认知的方法来描述本科生在描述和解释钾离子通道结构和功能的增强现实（AR）模型时的手势。我们的分析揭示了学生使用的两种手势制作的新模式，以及在生物化学内容的不同类别中相互关联的共同手势集。此外，我们还介绍了三个案例，这些案例强调了与三维 AR 可视化互动后手势的变化。这些观察结果凸显了在生物化学本科教育中以学习者为中心的教学法中关注手势的重要性。
期刊介绍：
CBE—Life Sciences Education (LSE), a free, online quarterly journal, is published by the American Society for Cell Biology (ASCB). The journal was launched in spring 2002 as Cell Biology Education—A Journal of Life Science Education. The ASCB changed the name of the journal in spring 2006 to better reflect the breadth of its readership and the scope of its submissions.
LSE publishes peer-reviewed articles on life science education at the K–12, undergraduate, and graduate levels. The ASCB believes that learning in biology encompasses diverse fields, including math, chemistry, physics, engineering, computer science, and the interdisciplinary intersections of biology with these fields. Within biology, LSE focuses on how students are introduced to the study of life sciences, as well as approaches in cell biology, developmental biology, neuroscience, biochemistry, molecular biology, genetics, genomics, bioinformatics, and proteomics.
