Most research on K-12 educational making has focused on tinkering with tangible and digital materials and processes within STEM disciplines like computing and engineering. Despite the growing fields of bioengineering and synthetic biology, far fewer studies have explored educational making possibilities in these realms. In this study we explore students’ engagement with biomaking, where people can make new materials and artifacts by genetically manipulating microorganisms. We examined 34 high school students’ experiences and reflections on making biologos by growing color pigments and making biosensors by creating fluorescent reactions. Through observations of workshop interactions and focus group interviews, we found that biomaking primarily engages students with assembly, or step-by-step, processes rather than experimentation or tinkering with materials. In the discussion we address the potentials and affordances of assembly practices in promoting rich learning experiences not just in biomaking, but also in other K-12 maker contexts.

Biohacking Food: A Case Study of Science Inquiry and Design Reflections about a Synthetic Biology High School Workshop.
In synthetic biology scientists genetically modify—or biohack—cells in order to repurpose their function or products. While synthetic biology is gaining societal relevance, few opportunities exist for K-12 students to have actual biodesign or biohacking experiences. To examine how high school students can use synthetic biology to engage not only in key science inquiry but also maker practices, we developed and implemented a workshop in which high school students genetically modified and repurposed yeast to produce and deliver vitamin A. Analyzing workshop observations and interviews of focus groups, we addressed the following research questions: (1) How did biodesign activities reflect science practices as characterized in national science standards? and (2) What did students have to say about their experiences with bio-design activities? In the discussion, we address what we learned about facilitating and improving biodesign in K-12 in classrooms.

While much research focused on making emphasizes digital and tangible media, few studies have explored making with biology, or biomaking, where people use cells as fabrication units to grow or “make” desired materials for designing real world applications. This lack is especially glaring considering how biomaking and related industries are often aligned with a growing push toward sustainable production as a way of addressing the pressing environmental issues of the day. In order address how maker frameworks could be used as a productive way of bringing biomaking into K-12 contexts, we report on the design and implementation of a biomaking workshop where teams of high school students both assembled a physical biosensor and imagined applications for this technology to address real world issues. Using classroom observations, analysis of classroom projects, and focus group interviews, we examined student experiences and perceptions of these activities in order to ask: What the affordances and challenges of biomaking in supporting maker learning, especially with regard to the less common practices of assembly and imagining? In the discussion, we review what we learned about facilitating biomaking in K-12 setting, as well how our analysis led us to a revaluation of the often crucial but neglected role assembly plays in more ‘typical’ maker activities, and the possibilities for enriching maker activities by including design prototyping and imagination.more » « less

Kong, S.C. (Ed.)This work aims to help high school STEM teachers integrate computational thinking (CT) into their classrooms by engaging teachers as curriculum co-designers. K-12 teachers who are not trained in computer science may not see the value of CT in STEM classrooms and how to engage their students in computational practices that reflect the practices of STEM professionals. To this end, we developed a 4-week professional development workshop for eight science and mathematics high school teachers to co-design computationally enhanced curriculum with our team of researchers. The workshop first provided an introduction to computational practices and tools for STEM education. Then, teachers engaged in co-design to enhance their science and mathematics curricula with computational practices in STEM. Data from surveys and interviews showed that teachers learned about computational thinking, computational tools, coding, and the value of collaboration after the professional development. Further, they were able to integrate multiple computational tools that engage their students in CT-STEM practices. These findings suggest that teachers can learn to use computational practices and tools through workshops, and that teachers collaborating with researchers in co-design to develop computational enhanced STEM curriculum may be a powerful way to engage students and teachers with CT in K-12 classrooms.more » « less

This fundamental research in pre-college education engineering study investigates the ways in which elementary school students and their teacher balance the tradeoffs in engineering design. STEM education reforms promote the engagement of K-12 students in the epistemic practices of disciplinary experts to teach content.1,2,3 This emphasis on practices is a paradigm shift that requires both extensive professional development and research to learn about the ways in which students and teacher learn about and participate in these practices. Balancing tradeoffs is an important practice in engineering but most often in classroom curricula it is embedded in the concept of iteration1,4; however, improving a design is not always the same as balancing trade-offs.1 Optimizing a multivariate problem requires students to engage in a number of engineering practices, like considering multiple solution, making tradeoffs between criteria and constraints, applying math and science knowledge to problem solving, constructing models, making evidence-based decisions, and assessing the implications of solutions5. The ways in which teachers and students collectively balance these tradeoffs in a design has been understudied1. Our primary research questions are, “How do teachers and students make decisions about making tradeoffs between criteria and constraints” and “How do experiences in teacher workshops affect the ways they implement engineering projects in their classes.” We take an ethnographic perspective to investigate these phenomena, and collected video data, field notes, student journals, and semi-structured interviews of eight elementary teachers in a workshop and similar data from two of the workshop teachers’ classes as they implemented the curriculum they learned in the workshop. Our analyses focus on the disciplinary practices teachers and students use to make decisions for balancing tradeoffs, how they are supported (or impeded) by teachers, and how they justify these decisions. Similarly, we compared two of the teachers wearing their “student hat” in the workshop as well as their “teacher hat” in the classroom5. Our analyses suggest three significant findings. First, teachers and students tended to focus on one criterion (e.g. cost, performance) and had few discussions about trying to minimize cost and maximize performance. Second, curriculum design significantly impacts the choices students make. Using two examples, we will show the impact of weighting criteria differently on the design strategies teachers and students make. Last, we noted most of the feedback given was related to managing classroom activity rather than supporting students’ designs. Implications of this study are relevant to both engineering educators and engineering curriculum developers.more » « less

When conducting a science investigation in biology, chemistry, physics or earth science, students often need to obtain, organize, clean, and analyze the data in order to draw conclusions about a particular phenomenon. It can be difficult to develop lesson plans that provide detailed or explicit instructions about what students need to think about and do to develop a firm conceptual understanding, particularly regarding data analysis. This article demonstrates how computational thinking principles and data practices can be merged to develop more effective science investigation lesson plans. The data practices of creating, collecting, manipulating, visualizing, and analyzing data are merged with the computational thinking practices of decomposition, pattern recognition, abstraction, algorithmic thinking, and automation to create questions for teachers and students that help them think through the underlying processes that happen with data during high school science investigations. The questions can either be used to elaborate lesson plans or embedded into lesson plans for students to consider how they are using computational thinking during their data practices in science.more » « less
