Given the ongoing socio-ecological crises, higher education institutions need curricular interventions to support students in developing the knowledge, skills, and perspectives needed to create a sustainable future. Campus farms are increasingly becoming sites for sustainability and environmental education toward this end. This paper describes the design and outcomes of a farm-situated place-based experiential learning (PBEL) intervention in two undergraduate biology courses and one environmental studies course over two academic years. We conducted a mixed-method study using pre/post-surveys and focus groups to examine the relationship between the PBEL intervention and students’ sense of place and expressions of pro-environmentalism. The quantitative analysismore »Free, publicly-accessible full text available May 1, 2023

Training the future synthetic biology workforce requires the opportunity for students to be exposed to biotechnology concepts and activities in secondary education. Detecting Wolbachia bacteria in arthropods using polymerase chain reaction (PCR) has become a common way for secondary students to investigate and apply recombinant DNA technology in the science classroom. Despite this important activity, cutting-edge biotechnologies such as clustered regularly interspaced short palindromic repeat (CRISPR)-based diagnostics have yet to be widely implemented in the classroom. To address this gap, we present a freeze-dried CRISPR-Cas12 sensing reaction to complement traditional recombinant DNA technology education and teach synthetic biology concepts.

This Work-In-Progress paper seeks to continue the development of a framework with which to organize engineering ethics instructional approaches. We build on a recent coding framework that was developed as part of a systematic review of US post-secondary engineering ethics education literature. We apply and iterate on the framework by analyzing the 2016 National Academy of Engineering report, “Infusing Ethics into the Development of Engineers: Exemplary Education Activities and Programs,” which includes two-page synopses of 25 exemplary ethics programs. By applying the framework to these exemplars, we aim to identify prominent instructional approaches utilized across NAE exemplars and the extentmore »

Over the past decade, the trade of counterfeit goods has increased. This has been enabled by advancements in low-cost digital printing methods (e.g., inkjet and laserjet) that are an asset for counterfeit production methods. However, each printing method produces characteristic printed features that can be used to identify not only the printing method, but also, uniquely identify the specific make and model of printer. This knowledge can be used for determination of whether or not the analyzed item is counterfeit. During the first phase of this research, chemical and physical analyses were performed on printed documents and ink samples formore »
