论文摘要
由于微观对象的非直觉行为和复杂的组装方法,学习微型化科学仍然具有挑战性。创建微型系统的传统方法需要昂贵的设备,设施和训练有素的员工。为了改善和民主化的微电位教育,我们创建了一项新的教育活动,使学生能够通过利用贴纸微流体来构建和测试先进的微流体,该贴纸由双面干膜粘合剂层组成。我们的活动与T-Mixers和Bubble Generators一起,是第一个使学生在课堂环境中构建阀门和F-Mixer的活动。这有助于强调设备制造的直观方面,例如使用层和层对齐的复杂的3二二级形状。此外,本文提供了第一个报道的定量数据,该数据涉及学生知识的显着改善和通过建立和测试几种常见设备的信心。在活动之后,所有11名学生都在概念的掌握和信心方面都有很大的改善。学生对指导反思的反应突出了该活动如何支持各种学习需求和偏好。鉴于对学生学习的影响,我们的低成本活动有助于减少全球小型化科学教育的障碍。
Learning miniaturization science remains challenging due to the non-intuitive behavior of microscale objects and complex assembly approaches. Traditional approaches for creating microsystems require expensive equipment, facilities, and trained staff. To improve as well as democratize microdevice education, we created a new educational activity that enables students to build and test advanced microfluidics by leveraging sticker microfluidics, composed of double-sided dry film adhesive layers. Along with T-mixers and bubble generators, our activity is the first to enable students to build a valve and F-mixer in the classroom setting. This helps emphasize less intuitive aspects of device manufacturing such as the creation of complex 3-dimenstional shapes with layers and layer alignment. In addition, this paper provides the first reported quantitative data on significant improvements in student knowledge and confidence from building and testing several common devices. All 11 students had substantial improvements in conceptual mastery and confidence after the activity. Student responses to a guided reflection highlight how the activity supports a variety of learning needs and preferences. Given the impact on student learning, our low-cost activity helps reduce global barriers to miniaturization science education.
