由于微尺度物体的非直观行为和专门的逐层组装方法，教育新生进行小型化科学仍然具有挑战性。在我们对现有文献的分析中，我们注意到，仍然很难有低成本的活动来引发深度学习。此外，很少有活动说明学习目标和衡量效果的标准。为此，我们创建了一个新的教育活动，使学生能够在课堂环境中使用廉价，广泛可用的材料构建和测试微流体混合器，阀门和气泡发生器。虽然本科和研究生工程专业的学生能够成功地构建设备，我们的活动是独一无二的，因为重点不是成功地构建和操作每个设备。相反，它是为了获得对小型化科学，设备设计和构造的理解，以便能够独立完成。我们的数据表明，该活动是适当的发展研究生和高级本科生（n = 57）的概念理解，以及使学生的持久印象。我们还报告了与学生误解模式相关的观察结果，以及小型化科学如何为教育研究人员提供了一个独特的机会来引发和研究误解。更广泛地说，由于这项活动向参与者传授了一种创建微系统的可行方法，并且可以在几乎任何全球环境中实施，因此我们的工作使小型化科学的教育民主化。注意到护理点技术在全球环境中的广泛潜力，这一活动可以增强当地专家的能力，以满足他们的需求。
Educating new students in miniaturization science remains challenging due to the non-intuitive behavior of microscale objects and specialized layer-by-layer assembly approaches. In our analysis of the existing literature, we noted that it remains difficult to have low cost activities that elicit deep learning. Furthermore, few activities have stated learning goals and measurements of effectiveness. To that end, we created a new educational activity that enables students to build and test microfluidic mixers, valves, and bubble generators in the classroom setting with inexpensive, widely-available materials. Although undergraduate and graduate engineering students are able to successfully construct the devices, our activity is unique in that the focus is not on successfully building and operating each device. Instead, it is to gain understanding about miniaturization science, device design, and construction so as to be able to do so independently. Our data show that the activity is appropriate for developing the conceptual understanding of graduate and advanced undergraduate students (n = 57), as well as makes a lasting impression on the students. We also report on observations related to student patterns of misunderstanding and how miniaturization science provides a unique opportunity for educational researchers to elicit and study misconceptions. More broadly, since this activity teaches participants a viable approach to creating microsystems and can be implemented in nearly any global setting, our work democratizes the education of miniaturization science. Noting the broad potential of point-of-care technologies in the global setting, such an activity could empower local experts to address their needs.
