Ramnarain, Umesh; Hlatshwayo, Manzini – South African Journal of Education, 2018
Despite growing consensus regarding the value of inquiry-based teaching and learning, the implementation of such a pedagogical practice continues to be a challenge for many South African teachers, especially at rural schools. The research reported in this article concerns the interaction between Grade 10 Physical Sciences teachers' beliefs about…

Kazeni, Monde; Baloyi, Eddy; Gaigher, Estelle – South African Journal of Education, 2018
The South African Physical Sciences Curriculum and Assessment Policy Statement (CAPS) requires learners to develop science inquiry skills, including Integrated Science Inquiry Skills (ISIS). However, the performance of learners in assessment tasks related to ISIS has been consistently poor over several years. The use of ineffective pedagogical…

Bannin, Timothy J.; Datta, Partha P.; Kiesewetter, Elizabeth T.; Kiesewetter, Matthew K. – Journal of Chemical Education, 2019
In this experiment, students are asked to conduct a catalytic cross-metathesis experiment and compare this reaction to the Wittig reaction within the confines of green chemistry. Students synthesize stilbene from styrene using Grubbs second-generation catalyst. Products can be minimally characterized by IR spectroscopy and melting point, but using…

Kean, Kelsey M.; van Zee, Kari; Mehl, Ryan A. – Journal of Chemical Education, 2019
The content and design scheme for a readily adaptable, research-based laboratory course in chemical biology are presented. In this course, students interrogate protein structure and function using the site-specific incorporation of noncanonical amino acids by genetic code expansion. The relatively new field of genetic code expansion enables…

Maass, Katja; Engeln, Katrin – Journal of Education and Training Studies, 2018
Although well researched in educational studies, inquiry-based learning, a student-centred way of teaching, is far away from being implemented in day-to-day science and mathematics teaching on a large scale. It is a challenge for teachers to adopt this new way of teaching in an often not supportive school context. Therefore it is important to…

Raboh, Ghada – Journal of Chemical Education, 2018
A high performance liquid chromatography (HPLC) experiment for the upper level analytical chemistry laboratory is described. The students consider the effect of mobile-phase composition and pH on the retention times of ionizable compounds in order to determine the acid dissociation constant, K[subscript a], of a phenolic acid. Results are analyzed…

Ghanem, Eman; Long, S. Reid; Rodenbusch, Stacia E.; Shear, Ruth I.; Beckham, Josh T.; Procko, Kristen; DePue, Lauren; Stevenson, Keith J.; Robertus, Jon D.; Martin, Stephen; Holliday, Bradley; Jones, Richard A.; Anslyn, Eric V.; Simmons, Sarah L. – Journal of Chemical Education, 2018
Innovative models of teaching through research have broken the long-held paradigm that core chemistry competencies must be taught with predictable, scripted experiments. We describe here five fundamentally different, course-based undergraduate research experiences that integrate faculty research projects, accomplish ACS accreditation objectives,…

Avent, Cherie M.; Boyce, Ayesha S.; LaBennett, Richard; Taylor, Darlene K. – Journal of Chemical Education, 2018
Mastery of core chemistry content is a degree requirement for several STEM majors. Gatekeeper courses, like general and physical chemistry, have a history of weeding out struggling students, and often underrepresented groups underperform. While gatekeeper courses ensure students are prepared for STEM degrees, it is essential they do not create…

King, Jorge H. Torres; Wang, Hong; Yezierski, Ellen J. – Journal of Chemical Education, 2018
Despite the importance of asymmetric catalysis in both the pharmaceutical and commodity chemicals industries, asymmetric catalysis is under-represented in undergraduate chemistry laboratory curricula. A novel guided-inquiry experiment based on the asymmetric aldol addition was developed. Students conduct lab work to compare the effectiveness of…

Hosker, Bill S. – Journal of Chemical Education, 2018
A highly simplified variation on the do-it-yourself spectrophotometer using a smartphone's light sensor as a detector and an app to calculate and display absorbance values was constructed and tested. This simple version requires no need for electronic components or postmeasurement spectral analysis. Calibration graphs constructed from two…

Boyd-Kimball, Debra; Miller, Keith R. – Journal of Chemical Education, 2018
Laboratory courses are often designed using step-by-step protocols which encourage students to conduct experiments without thinking about what they are doing or why they are doing it. Such course design limits the growth of our students as scientists and can make it more difficult for a student to transition to the expectations of a research…

Skelton, Peter; Blackburn, J. Joey; Stair, Kristin S.; Levy, Natalie; Dormody, Thomas J. – Journal of Agricultural Education, 2018
Inquiry-based teaching methods have been found to enhance students' abilities to understand the process of scientific inquiry. The purpose of this study was to determine if middle school students taught through an inquiry-based teaching approach consisting of scientific skill development, scientific knowledge, and scientific reasoning were more…

Schuster, Mariah L.; Peterson, Karl P.; Stoffregen, Stacey A. – Journal of Chemical Education, 2018
This two-period undergraduate laboratory experiment involves the synthesis of a mixture of isomeric unknowns, isolation of the mixture by means of distillation, and characterization of the two products primarily by NMR spectroscopy (1D and 2D) supported with IR spectroscopy and GC-MS techniques. Subsequent calculation and examination of the…

Latimer, Devin R.; Ata, Athar; Forfar, Christopher P.; Kadhim, Mustafa; McElrea, April; Sales, Ramon – Journal of Chemical Education, 2018
This guided-inquiry, upper-division undergraduate organic lab experiment, a hybrid of problem-based learning (PBL); process-oriented, guided-inquiry learning (POGIL); and peer-led team learning (PLTL) has been developed to ease the transition from the undergraduate lab to a research lab environment. The characterization of a mixture of camphor and…

Dyer, Robert M. B.; Venton, B. Jill; Maeng, Jennifer L. – Journal of Chemical Education, 2018
University of Virginia, like many other universities, has developed a chemistry outreach program (called Chemistry Learning through Experimentation, Awareness, and Demonstration; i.e., Chemistry LEAD) that visits K-5 schools and teaches inquiry-based chemistry lessons in order to engage local students with science. Chemistry LEAD is graduate…
