Bunce, Diane M.; Komperda, Regis; Dillner, Debra K.; Lin, Shirley; Schroeder, Maria J.; Hartman, JudithAnn R. – Journal of Chemical Education, 2017
Students with an insufficient amount of time to study are becoming more prevalent in the general college population as many who enroll in college have competing responsibilities (full-time jobs, childcare, etc.). Such students are likely to choose study resources that they consider to be both effective and efficient. Students at the U.S. Naval…

Wheeler, Lindsay B.; Maeng, Jennifer L.; Whitworth, Brooke A. – Journal of Chemical Education, 2017
The purpose of this investigation was to explore changes in undergraduate and graduate teaching assistants' (TAs') content knowledge and beliefs about teaching within the context of an inquiry-based laboratory course. TAs received professional development (PD), which was informed by the TA training literature base and was designed for TAs…

Gibbons, Rebecca E.; Laga, Emily E.; Leon, Jessica; Villafan~e, Sachel M.; Stains, Marilyne; Murphy, Kristen; Raker, Jeffrey R. – Journal of Chemical Education, 2017
Research on classroom response systems (CRSs) in chemical education has primarily focused on the development of evidence-based strategies for implementation and novel practitioner uses of CRSs in instructional practice. Our national survey of postsecondary chemistry faculty extends these discussions, providing a broad-based understanding of the…

Box, Melinda C.; Dunnagan, Cathi L.; Hirsh, Lauren A. S.; Cherry, Clinton R.; Christianson, Kayla A.; Gibson, Radiance J.; Wolfe, Michael I.; Gallardo-Williams, Maria T. – Journal of Chemical Education, 2017
This study was designed to evaluate the effectiveness of student-generated videos as a supplement to teaching assistant (TA) instruction in an undergraduate organic chemistry laboratory. Three videos covering different aspects of lab instruction (experimental technique, use of instrumentation, and calculations) were produced using…

Christiansen, Michael A.; Lambert, Alyssia M.; Nadelson, Louis S.; Dupree, Kami M.; Kingsford, Trish A. – Journal of Chemical Education, 2017
We recently shared our design of a two semester flipped organic chemistry course in which we gave students in-class quizzes to incentivize attendance and watching the lecture videos in advance. With a second iteration, we planned to make the video-watching experience more engaging. We accordingly hypothesized that if students completed short…

Hawker, Morgan J.; Dysleski, Lisa; Rickey, Dawn – Journal of Chemical Education, 2016
Metacognitive monitoring of one's own understanding plays a key role in learning. An aspect of metacognitive monitoring can be measured by comparing a student's prediction or postdiction of performance (a judgment made before or after completing the relevant task) with the student's actual performance. In this study, we investigated students'…

Garcia, Jennifer; Schultz, Linda D. – Journal of Chemical Education, 2016
The classic technique for sulfate analysis in an undergraduate quantitative analysis lab involves precipitation as the barium salt with barium chloride, collection of the precipitate by gravity filtration using ashless filter paper, and removal of the filter paper by charring over a Bunsen burner. The entire process is time-consuming, hazardous,…

Gerczei, Timea – Journal of Chemical Education, 2016
The work presented here is the summary of a 3 year study that aimed to uncover how students' perception of science changes with the chance to participate in a mini-conference that is incorporated into the biochemistry lecture course. Students were asked to work in groups of 2 or 3 and research a topic that is related to the material covered in…

Mabrouk, Patricia Ann – Journal of Chemical Education, 2016
Over a three-year period, chemistry and engineering students participating in six Research Experience for Undergraduates (REU) programs were surveyed before and after participating in a research ethics training workshop. The goal was to learn what undergraduate students already knew about key concepts in research ethics at the start of their…

Warfa, Abdi-Rizak M. – Journal of Chemical Education, 2016
A meta-analysis of recent quantitative studies that examine the effects of cooperative learning (CL) on achievement outcomes in chemistry is presented. Findings from 25 chemical education studies involving 3985 participants (N[subscript treatment] = 1,845; N[subscript control] = 2,140) and published since 2001 show positive association between…

Warner, Don L.; Brown, Eric C.; Shadle, Susan E. – Journal of Chemical Education, 2016
Academic programs generally work to make their laboratory curriculum both as instrumentation rich and up to date as possible. However, little is known about the relationship between the use of instrumentation in the curriculum and student learning. As part of our department's ongoing assessment efforts, a project was designed to probe this…

Drury, Sara A. Mehltretter; Stucker, Kyle; Douglas, Anthony; Rush, Ryan A.; Novak, Walter R. P.; Wysocki, Laura M. – Journal of Chemical Education, 2016
A central goal of nonmajors chemistry courses is to instill within students the sense that chemistry does not occur in a vacuum but rather permeates everyday life. To encourage students to consider chemistry within the broader context of society and public policy, a week-long module in a survey course for nonmajors was designed to connect…

Jordan, Jeremy T.; Box, Melinda C.; Eguren, Kristen E.; Parker, Thomas A.; Saraldi-Gallardo, Victoria M.; Wolfe, Michael I.; Gallardo-Williams, Maria T. – Journal of Chemical Education, 2016
Multimedia instruction has been shown to serve as an effective learning aid for chemistry students. In this study, the viability of student-generated video instruction for organic chemistry laboratory techniques and procedure was examined and its effectiveness compared to instruction provided by a teaching assistant (TA) was evaluated. After…

Hibbard, Lisa; Sung, Shannon; Wells, Breche┬┤ – Journal of Chemical Education, 2016
Flipped learning has come to the forefront in education. It maximizes learning by moving content delivery online, where learning can be self-paced, allowing for class time to focus on student-centered active learning. This five-year cross-sectional study assessed student performance in a college general chemistry for majors sequence taught by a…

Kimberlin, Stephanie; Yezierski, Ellen – Journal of Chemical Education, 2016
Students' inaccurate ideas about what is represented by chemical equations and concepts underlying stoichiometry are well documented; however, there are few classroom-ready instructional solutions to help students build scientifically accurate ideas about these topics central to learning chemistry. An intervention (two inquiry-based activities)…
