Davis, Eric J.; Pauls, Steve; Dick, Jonathan – Journal of Chemical Education, 2017
Presented is a project-based learning (PBL) laboratory approach for an upper-division environmental chemistry or quantitative analysis course. In this work, a combined laboratory class of 11 environmental chemistry students developed a method based on published EPA methods for the extraction of dichlorodiphenyltrichloroethane (DDT) and its…

Kloser, Matthew J.; Brownell, Sara E.; Shavelson, Richard J.; Fukami, Tadashi – Journal of College Science Teaching, 2013
Undergraduate biology lab courses have long been criticized for engaging students in "cookbook" experiences in which students follow a given protocol to collect data that help answer a predetermined question. Recent reform documents in biology education have suggested that students should engage in lab courses that provide more authentic…

Selco, Jodye I.; Bruno, Mary; Chan, Sue – Journal of Chemical Education, 2012
A hands-on, minds-on inquiry chemistry experiment was developed for use in K-12 schools that enables students to combine the chemicals of their choice and observe the results. The chemistry involved is water based and builds upon acid-base, double displacement, and iodometric detection of starch reactions. Chemicals readily available in the…

Knight, Jonathan D.; Fulop, Rebecca M.; Marquez-Magana, Leticia; Tanner, Kimberly D. – CBE - Life Sciences Education, 2008
Active-learning strategies are increasingly being integrated into college-level science courses to make material more accessible to all students and to improve learning outcomes. One active-learning pedagogy, case-based learning (CBL), was developed as a way to both enhance engagement in the material and to accommodate diverse learning styles.…
