Here we discuss the design and implementation of an introductory DNA Barcoding module that we developed for the University of Hawai‘i at Mānoa’s Science in Action Program, a two-week summer program that teaches high school students about Hawai‘i’s biodiversity. Students used the concept of characterization to explain the relationships among organisms using morphological, ecological, and molecular data. Additionally, students gained experience in the scientific practice of generating explanations by gathering multiple lines of evidence to support or refute a claim, linking claims with evidence, and presenting such claims in written and oral formats to identify unknown algae samples. During this activity, students also gained real-world research experience in the field of biodiversity research. We also discuss potential modifications for future iterations of this module. 

As part of the Institute for Scientist and Engineer Educators Professional Development Program (PDP), our team designed an activity for the Akamai internship program’s Preparation for Research Experiences and Projects (PREP) course. The activity focused on content around different renewable energy and storage technologies, and the widely applicable engineering practice of optimization through iteration and evaluating trade-offs. Here we describe the overall activity, with primary emphasis on how the PDP backward design process and integration of the Equity & Inclusion (E&I) theme led us to design and implement a unique model we call the “expert training model” that has important E&I implications. We found that an educational activity design that focuses on E&I considerations, such as identifying multiple ways to productively participate and developing learners’ identity in STEM, simultaneously satisfies criteria for being an engaging and authentic STEM experience. We also reflect on potential pitfalls and ways to improve and adapt this model.
