Williams, Leah C.; Reddish, Michael J. – Journal of Chemical Education, 2018
Many chemistry laboratory exercises follow a given protocol with known results. Such traditional laboratories rarely give students an accurate representation of how research is conducted, the scientific practices involved in research, and the ownership that accompanies developing and carrying out an independent project. Several laboratory reforms…

George-Williams, Stephen R.; Soo, Jue T.; Ziebell, Angela L.; Thompson, Christopher D.; Overton, Tina L. – Chemistry Education Research and Practice, 2018
Many examples exist in the chemical education literature of individual experiments, whole courses or even entire year levels that have been completely renewed under the tenets of context-based, inquiry-based or problem-based learning. The benefits of these changes are well documented and include higher student engagement, broader skill development…

Beck, Rachel C.; Erdmann, Mitzy A. – Journal of Chemical Education, 2018
Identification and quantification of an unknown illicit drug (cocaine) from both simulated drug paraphernalia and simulated urine can be achieved via direct analysis in real time (DART) triple quadrupole linear ion trap (QTRAP) mass spectrometry (MS). We describe a novel, hands-on laboratory activity which utilizes the recent DART technology…

Students' Understanding and Perceptions of Assigned Team Roles in a Classroom Laboratory Environment
Ott, Laura E.; Kephart, Kerrie; Stolle-McAllister, Kathleen; LaCourse, William R. – Journal of College Science Teaching, 2018
Using a cooperative learning framework in a quantitative reasoning laboratory course, students were assigned to static teams of four in which they adopted roles that rotated regularly. The roles included: team leader, protocol manager, data recorder, and researcher. Using a mixed-methods approach, we investigated students' perceptions of the team…

Sibbernsen, Kendra J. – Journal of Astronomy & Earth Sciences Education, 2014
A mixed-method quasi-experimental study was designed to determine how 130 undergraduates in an introductory astronomy survey course laboratory changed their understanding of scientific inquiry working as individuals in relative isolation compared to working in small, collaborative learning groups when using specially designed astronomy curricula…

Erol, Mustafa; Buyuk, Ugur; Tanik Onal, Nagihan – Educational Sciences: Theory and Practice, 2016
The inadequacy of experimental activities (or lack of equipment) in science courses in rural parts of Turkey negatively effects students' acquisition of scientific thinking and inquiry skills. The fact that success rates are notably low in international assessments demonstrates the necessity to adopt "different" approaches apart from the…

Wilson, Meredith – ProQuest LLC, 2012
Geologic field trips are among the most beneficial learning experiences for students as they engage the topic of geology, but they are also difficult environments to maximize learning. This action research study explored one facet of the problems associated with teaching geology in the field by attempting to improve the transition of undergraduate…
