Science, Technology, Engineering, and Mathematics (STEM) Education Faculty Publications

We introduce a conceptual framework of K-12 STEM literacy that rightfully and intentionally positions each and every student, particularly minoritized groups, as belonging in STEM. In order to conceptualize the equity-based framework of STEM literacy, we conducted a systematic review of literature related to STEM literacy, which includes empirical studies that contribute to STEM literacy. The literature on the siloed literacies within STEM (i.e., science, technology, engineering, and mathematics literacy) also contributed to formulate the necessity of and what it means to develop STEM literacy. The Equity-Oriented STEM Literacy Framework illuminates the complexities of disrupting the status quo and ...

Biodiversity Monitoring And Volunteer Motivations: A Case Study On The Imagined Communities Of Citizen Scientists In Meinung, Taiwan, Serena May Calcagno

Master's Projects and Capstones

The Asia Pacific’s biodiversity is under threat. One significant step that can improve conservation is gathering data on what species exist in different areas over time, which can provide insight into ecosystem health. This is especially important in biodiversity hotspots, where high levels of endemism and anthropogenic risk overlap. Though it is one of the few places in the Pacific not classified as a biodiversity hotspot, Taiwan has an unusually high saturation in terms of biodiversity data points. Investigating the motives of biodiversity monitoring volunteerism is already a topic of growing scholarly interest, but relatively few studies have focused ...

Modeling Functions: Modified Falling Ladder Task, Nakia Salam

Symposium of Student Scholars

Modeling Functions: Modified Falling Ladder Task

By the time students graduate from high school, the knowledge of functions has shifted from a conceptual understanding to a procedural approach, where the understanding of functions is based upon memorized computational steps that can’t be modeled. A focus on the computational aspect of functions can have a long-term effect on students’ ability to understand the meaning of functional relationships, negatively affecting their overall ability to reason mathematically. Without educators making a conscious decision to recognize the value of modeling and force its’ inclusion, there are few opportunities to experience the application of ...
