Wietsma, Jan Jaap; van der Veen, Jan T.; Buesink, Wilfred; van den Berg, Albert; Odijk, Mathieu – Journal of Chemical Education, 2018
Lab-on-a-chip technology is brought into the classroom through development of a lesson series with hands-on practicals. Students can discover the principles of microfluidics with different practicals covering laminar flow, micromixing, and droplet generation, as well as trapping and counting beads. A quite affordable novel production technique…

Cukurova, Mutlu; Bennett, Judith; Abrahams, Ian – Research in Science & Technological Education, 2018
Background: Recently, there is a growing interest in independent learning approaches globally. This is, at least in part, due to an increased demand for so-called "21st century skills" and the potential of independent learning to improve student skills to better prepare them for the future. Purpose: This paper reports a study that…

Cintamulya, Imas; Mawartiningsih, Lilik – Asia-Pacific Forum on Science Learning and Teaching, 2018
The plant taxonomy textbooks that are generally used in colleges need to be complemented with a DNA-based molecular review. In general, plant taxonomy textbooks devote more space to morphology than to molecular-level characteristics. The research reported here used the results of DNA-based research to develop a molecular plant taxonomy textbook.…

Manneh, Ilana A.; Rundgren, Carl-Johan; Hamza, Karim M.; Eriksson, Lars – International Journal of Science Education, 2018
In this study, we explore the issues and challenges involved in supporting students' learning to discern relevant and critical aspects of determining oxidation states of atoms in complex molecules. We present a detailed case of an interaction between three students and a tutor during a problem-solving class, using the analytical tool of practical…

Hoffmann, Roald – International Journal for Talent Development and Creativity, 2016
This article makes a case for a positive role of tension in the creative process in chemistry. I begin with an argument that there is an inherent tension in what makes molecules interesting--their positioning along various polar axes. One of these, the age-old differentiation between useful (to society and for personal profit) commercialization…

Stull, Andrew T.; Gainer, Morgan; Padalkar, Shamin; Hegarty, Mary – Journal of Chemical Education, 2016
Mastering the many different diagrammatic representations of molecules used in organic chemistry is challenging for students. This article summarizes recent research showing that manipulating 3-D molecular models can facilitate the understanding and use of these representations. Results indicate that students are more successful in translating…

Vasquez, Thomas E., Jr.; Saldan~a, Cristina; Muzikar, Katy A.; Mashek, Debra; Liu, Jane M. – Journal of Chemical Education, 2016
This laboratory experiment provides undergraduate students enrolled in organic chemistry the opportunity to design and synthesize their own peptide, which is then tested for antimicrobial activity. After reading a primary scientific paper on antimicrobial peptides, students design and synthesize their own hexapeptide that they hypothesize will…

Wallace, Colin S.; Prather, Edward E.; Hornstein, Seth D.; Burns, Jack O.; Schlingman, Wayne M.; Chambers, Timothy G. – Physics Teacher, 2016
Light and spectroscopy are among the most important and frequently taught topics in introductory college-level general education astronomy courses (hereafter Astro 101). This is due to the fact that the vast majority of observational data studied by astronomers arrives at Earth in the form of light. While there are many processes by which matter…

Robertson, Carol – Science Teacher, 2016
Deoxyribonucleic acid (DNA) is life's most amazing molecule. It carries the genetic instructions that almost every organism needs to develop and reproduce. In the human genome alone, there are some three billion DNA base pairs. The most difficult part of teaching DNA structure, however, may be getting students to visualize something as small as a…

Lakin, Joni M.; Han, Yi; Davis, Edward – Journal of STEM Education: Innovations and Research, 2016
The "Grand Challenges" for Engineering are an effort to portray engineering as a field that has profound impacts on society. This study explores the level of interest first-year engineering students had in various "Grand Challenges" and in nanotechnology topics. We administered a survey to a large sample of students enrolled in…

Ardiel, Evan L.; Giles, Andrew C.; Yu, Alex J.; Lindsay, Theodore H.; Lockery, Shawn R.; Rankin, Catharine H. – Learning & Memory, 2016
Habituation is a highly conserved phenomenon that remains poorly understood at the molecular level. Invertebrate model systems, like "Caenorhabditis elegans," can be a powerful tool for investigating this fundamental process. Here we established a high-throughput learning assay that used real-time computer vision software for behavioral…

Thayer, Kelly M. – Biochemistry and Molecular Biology Education, 2016
Analyzing protein structure has become an integral aspect of understanding systems of biochemical import. The laboratory experiment endeavors to introduce protein folding to ascertain structures of proteins for which the structure is unavailable, as well as to critically evaluate the quality of the prediction obtained. The model system used is the…

Rothe, Erhard W.; Zygmunt, William E. – Chemical Engineering Education, 2016
We inserted a self-taught molecular modeling project into an otherwise conventional undergraduate chemical-reaction-engineering course. Our objectives were that students should (a) learn with minimal instructor intervention, (b) gain an appreciation for the relationship between molecular structure and, first, macroscopic state functions in…

Witherow, D. Scott – Biochemistry and Molecular Biology Education, 2016
This work describes a 10-week laboratory project studying wild-type and mutant bacterial alkaline phosphatase, in which students purify, quantitate, and perform kinetic assays on wild-type and selected mutants of the enzyme. Students also perform plasmid DNA purification, digestion, and gel analysis. In addition to simply learning important…

Best, Katherine T.; Li, Diana; Helms, Eric D. – Journal of Chemical Education, 2017
The electrophilic addition of a hydrohalic acid (HX) to an alkene is often one of the first reactions learned in second-year undergraduate organic chemistry classes. During the ensuing discussion of the mechanism, it is shown that this reaction follows Markovnikov's rule, which states that the hydrogen atom will attach to the carbon with fewer…
