Direct linkJeffery, Kathleen A.; Frawley Cass, Samantha M.; Sweeder, Ryan D. – Journal of STEM Education: Innovations and Research, 2019
This study examines differences in the ability of undergraduate students, taught in lecture-based or context-based general chemistry courses, to describe reaction kinetics. The subjects included 210 students from a residential science college at a large research university. Two open-ended questions were used to engage students' surface knowledge…

Graulich, Nicole; Schween, Michael – Journal of Chemical Education, 2018
Acquiring conceptual understanding seems to be one of the main challenges students face when studying organic chemistry. Traditionally, organic chemistry presents an extensive variety of chemical transformations, which often lead students to recall an organic transformation rather than apply conceptual knowledge. Strong surface level focus and…

Tang, Hui; Abraham, Michael R. – Journal of Chemical Education, 2016
Computer-based simulations can help students visualize chemical representations and understand chemistry concepts, but simulations at different levels of representation may vary in effectiveness on student learning. This study investigated the influence of computer activities that simulate chemical reactions at different levels of representation…

Tural, Guner – Asia-Pacific Forum on Science Learning and Teaching, 2014
The effects of the context-based approach have been discussed in educational settings as one of the innovative instructional approaches. Many countries throughout the world have implemented context-based physics projects or programs to make physics more relevant to students' lives. This paper examined the effects of context-based physics…

Perles, Carlos E.; Volpe, Pedro L. O. – Journal of Chemical Education, 2008
A simple commercial blood glucose meter is used to follow the kinetics of mutarotation of D-glucose in aqueous solution. The results may be compared with those obtained using an automatic polarimeter, if this is available This experiment is proposed for use by students in a general chemistry, biology, organic chemistry, and physical chemistry…

Aldahmash, Abdulwali H.; Abraham, Michael R. – Journal of Chemical Education, 2009
Using animated computer-generated graphics to assist instruction has recently attracted the attention of educators and educational researchers. The specific focus of this study is to compare the influence of animated visuals with static visuals on college students' understanding of organic reaction mechanisms in chemistry. This study also focuses…
