Stephens, Philip J. – World Journal of Education, 2017
The purpose of this study is to determine whether viewing narrated video clips improves student learning. The study was conducted with undergraduate, mostly Biology majors, in an Animal Physiology course held in successive semesters. When both classes were given the same face-to-face lectures and identical online resources their performance on an…

Niederer, Kyle A.; Fodor, Matthew D.; Catino, Arthur J. – Journal of Chemical Education, 2018
Torsional effects influence kinetic selectivity in a wide range of organic transformations. As such, textbooks commonly use Newman projections to illustrate the torsional effects that arise in their transition states. Unfortunately, these representations fall short when the reaction occurs "within a ring." In many cases, the torsional…

Miller, Diane M.; Chengelis Czegan, Demetra A. – Journal of Chemical Education, 2016
This paper describes assignments that have been implemented in a General Chemistry I course to promote science literacy. This course was chosen in particular because it reaches a broad audience, which includes nonscience majors. The assignment series begins with several discussions and tasks to develop information literacy, in which students find…

Danowitz, Amy M.; Brown, Ronald C.; Jones, Clinton D.; Diegelman-Parente, Amy; Taylor, Christopher E. – Journal of Chemical Education, 2016
Undergraduate research is an important capstone experience that provides students with the conceptual and technical aptitude for graduate or industrial research. However, this experience is often compressed into a single term in a course-based undergraduate research experience (CURE) or run by individual faculty members for select students on an…

Guron, Marta; Paul, Jared J.; Roeder, Margaret H. – Journal of Chemical Education, 2016
Although much of the scientific community concerns itself with ideas of a sustainable future, very little of this interest and motivation has reached the classroom experience of the average chemistry major, and therefore, it is imperative to expose students to these ideas early in their careers. The focus of most undergraduate chemistry curricula…

Nigam, Manisha; Rush, Brittney; Patel, Jay; Castillo, Raul; Dhar, Preeti – Journal of Chemical Education, 2016
A green, aza-Michael reaction is described that can be used to teach undergraduate students conjugate addition of nitrogen nucleophile to an a,ß-unsaturated ester. Students analyze spectral data of the product obtained from the assigned reaction to determine product structure and propose the mechanism of its formation. The experiment requires…

Kennedy, Sarah A. – Journal of Chemical Education, 2016
The green chemistry course taught at Westminster College (PA) incorporates nontraditional teaching techniques and texts to educate future chemists about the importance of using green chemistry principles. The course is designed to introduce green chemistry concepts and demonstrate their inherent necessity by discussing historical missteps by the…

Young, Sherri C.; Colabroy, Keri L.; Baar, Marsha R. – Journal of Chemical Education, 2016
The laboratory is a mainstay in STEM education, promoting the development of critical thinking skills, dexterity, and scientific curiosity. The goals in the laboratory for nonchemistry, prehealth majors, though, could be distinguished from those for chemistry majors. In service courses such as organic chemistry, much laboratory time is often spent…

Bendorf, Holly D.; Vebrosky, Emily N.; Eck, Brian J. – Journal of Chemical Education, 2016
In this experiment for an upper-division course in organic structure determination, each student prepares an unknown compound and characterizes the product using multiple spectroscopic techniques. The unknowns, 2-aryl-substituted 1,4-dihydro-3,1-benzoxazines and 1,2,3,4-tetrahydroquinazolines, are prepared in a single step by the condensation of…

Logan, Jennifer L.; Quin~ones, Rosalynn; Sunderland, Deborah P. – Journal of Chemical Education, 2015
An assignment incorporating posters into a second-year analytical chemistry lab is described. Students work in groups and are assigned one of the application-themed weekly laboratories as a topic. Course data acquired for these weekly laboratories are compiled into spreadsheets that the poster group then analyzes to present in an on-campus poster…

Cook, Deborah H. – Journal of Chemical Education, 2014
Conflicts in Chemistry: The Case of Plastics, an innovative role-playing activity for high school students, was developed by the Chemical Heritage Foundation to promote increased public understanding of chemistry. The pilot program included three high school teachers and their students at three different schools and documented implementation and…

Davenport, Jodi L.; Leinhardt, Gaea; Greeno, James; Koedinger, Kenneth; Klahr, David; Karabinos, Michael; Yaron, David J. – Journal of Chemical Education, 2014
Two suggestions for instruction in chemical equilibrium are presented, along with the evidence that supports these suggestions. The first is to use diagrams to connect chemical reactions to the effects of reactions on concentrations. The second is the use of the majority and minority species (M&M) strategy to analyze chemical equilibrium…

Chase, Catherine C.; Klahr, David – Journal of Science Education and Technology, 2017
An important, but as yet unresolved pedagogical question is whether discovery-oriented or direct instruction methods lead to greater learning and transfer. We address this issue in a study with 101 fourth and fifth grade students that contrasts two distinct instructional methods. One is a blend of discovery and direct instruction called…

Amaral, Katie E.; Shank, John D.; Shibley, Ivan A., Jr.; Shibley, Lisa R. – Journal of Chemical Education, 2013
General Chemistry I historically had one of the highest failure and withdrawal rates at Penn State Berks, a four-year college within the Penn State system. The course was completely redesigned to incorporate more group work, the use of classroom response systems, peer mentors, and a stronger online presence via the learning management system…

Manchanayakage, Renuka – Journal of Chemical Education, 2013
Two green chemistry courses have been introduced into the liberal arts curriculum at Susquehanna University. Green chemistry was integrated into an existing course, Chemical Concepts, and offered as Green Chemical Concepts for nonscience majors. This course is designed to instill an appreciation for green chemistry in a large and diverse group of…
