Science students can benefit from visual aids. In biology lectures, visual aids are usually limited to tables, figures, and PowerPoint presentations. In this IRB-approved study, we examined the effectiveness of the use of five prop demonstrations, three of which are at the intersection of biology and chemistry, in three community college biology courses. We hypothesized that students' performance on test questions is enhanced by the use of prop demonstrations. Consistent with our hypothesis, we showed that students learn more effectively and perform better on questions that relate to demonstrations than on questions related to lessons that do not have a demonstration component.
理科学生可以从视觉辅助工具中受益。在生物学讲座中，视觉辅助工具通常仅限于表格、图表和PowerPoint演示文稿。在这项经机构审查委员会批准的研究中，我们在三门社区学院生物学课程中考察了使用五个道具演示（其中三个处于生物学和化学的交叉领域）的效果。我们假设，使用道具演示可提高学生在测试题上的表现。与我们的假设一致，我们发现，与没有演示部分的课程相关的问题相比，学生在与演示相关的问题上学习更有效，表现也更好。
