Tietz, Paul I. – Natural Sciences Education, 2019
Hydraulic fracturing is a major process for oil and natural gas production in the United States, and sand mines in Western Wisconsin provide highly desirable sand for the fracturing industry. After being mined, sand is wet-sieved to isolate economical-size fractions. Polyacrylamide is used as a flocculant to settle out the fine particles,…

Anderson, Laurel J.; Dosch, Jerald J.; Lindquist, Erin S.; McCay, Timothy S.; Machado, Jose-Luis; Kuers, Karen; Gartner, Tracy B.; Shea, Kathleen L.; Mankiewicz, Carol; Rodgers, Vikki L.; Saunders, Patricia A.; Urban, Rebecca A.; Kilgore, Jason S.; Powell, Amanda S.; Ramage, Benjamin S.; Steinweg, J. Megan; Straub, Jacob N.; Bunnell, Sarah L.; Witkovsky-Eldred, Marissa – Scholarship and Practice of Undergraduate Research, 2020
Multisite, course-based undergraduate research experiences (CUREs) in the Ecological Research as Education Network (EREN) were assessed for impacts on student learning of collaborative science skills using a survey that could serve as a starting point for a validated assessment instrument for multisite CUREs. Pretests/posttests were administered…

Shaner, Sarah E.; Hooker, Paul D.; Nickel, Anne-Marie; Leichtfuss, Amanda R.; Adams, Carissa S.; de la Cerda, Dionisia; She, Yuqi; Gerken, James B.; Pokhrel, Ravi; Ambrose, Nicholas J.; Khaliqi, David; Stahl, Shannon S.; Schuttlefield Christus, Jennifer D. – Journal of Chemical Education, 2016
Electrochemical water oxidation is a major focus of solar energy conversion efforts. A new laboratory experiment has been developed that utilizes real-time, hands-on research to discover catalysts for solar energy conversion. The HARPOON, or Heterogeneous Anodes Rapidly Perused for Oxygen Overpotential Neutralization, experiment allows an array of…

Cronje, Ruth; Murray, Kelly; Rohlinger, Spencer; Wellnitz, Todd – International Journal of Science Education, 2013
Our objective was to investigate the impact of the Science Writing Heuristic (SWH) on undergraduates' ability to express logical conclusions and include appropriate evidence in formal writing assignments. Students in three laboratory sections were randomly allocated to the SWH treatment ("n"?=?51 students) with another three sections…

Lu, Fong-Mei; Eliceiri, Kevin W.; Squirrell, Jayne M.; White, John G.; Stewart, James – CBE - Life Sciences Education, 2008
This study was undertaken to gain insights into undergraduate students' understanding of early embryonic development, specifically, how well they comprehend the concepts of volume constancy, cell lineages, body plan axes, and temporal and spatial dimensionality in development. To study student learning, a curriculum was developed incorporating…
