Analytical Thinking, Analytical Action
The November 2016 issue of the Journal of Chemical Education is now available online to subscribers. Topics featured in this issue include: electrochemistry; researching how assessment aids learning; using technology to teach; environmental chemistry; hands-on, minds-on activities and demonstrations; geology-inspired chemistry.
Learning electrochemical analysis and techniques is critical for students to develop conceptual understanding and gain practical skills. Researchers use electrochemistry to analyze a variety of systems extending from molecules to materials that encompass research themes ranging from clean energy to substrate activation in biological systems. In Introduction to Electrochemistry and the Use of Electrochemistry to Synthesize and Evaluate Catalysts for Water Oxidation and Reduction, Samuel J. Hendel and Elizabeth R. Young describe a lab to familiarize students with electrochemistry as well as quantitative electrochemical characterization and analysis. Students are introduced to the fundamentals of experimental electrochemistry using the ferricyanide/ferrocyanide redox couple as a model system. Students then conduct electrochemical analyses of the water electrolysis reaction and identify catalysts for both hydrogen and oxygen generation in the reductive and oxidative half-reactions, respectively. These experiments are discussed in the context of clean energy storage to promote the connection of the teaching laboratory to real-world applications.
Editor-in-Chief Norbert J. Pienta has been traveling around the world to discuss matters of common interest concerning teaching and learning within introductory chemistry courses. Read about his latest travels in Innocents Abroad, Redux: Latin America.
