Addition Reactions of Alkenes The Diels-Alder reaction, addition of oxygen to tetrakis(N, N-dimethylamino) ethylene, polymerization of ethylene, and addition of iodine to a-pinene are demonstrated. Molecular models of ethene are shown.
Synthesis Explorer: A Chemical Reaction Tutorial System for Organic Synthesis Design and Mechanism PredictionJonathan H. Chen and Pierre Baldi Synthesis Explorer is an interactive tutorial system for organic chemistry that enables students to learn chemical reactions in ways previously unrealized. Pedagogical experiments in undergraduate classes at UC Irvine indicate that the system can improve average student examination performance by ~10%. Chen, Jonathan H.; Baldi, Pierre. J. Chem. Educ.2008, 85, 1699.

Experimental Design and Optimization: Application to a Grignard ReactionNaoual Bouzidi and Christel Gozzi This 5-week project, which systematically investigates optimizing the synthesis of benzyl-1-cyclopentan-1-ol, constitutes an initiation into research methodology and experimental design to prepare the student-engineer for an industry internship. Other pedagogical goals include experience in synthetic techniques, obtaining reproducible yields, and using quantitative analysis methods. Bouzidi, Naoual; Gozzi, Christel. J. Chem.

Saying What You Mean: Teaching Mechanisms in Organic ChemistryJ. Brent Friesen Ways to maintain clarity and consistency when teaching reaction mechanisms in organic chemistry include the use of balanced reaction equations, avoiding the use of shortcut notations, including key electrons and bonds in structural representations, and distinguishing between covalent and ionic bonds. Friesen, J. Brent. J. Chem. Educ.2008, 85, 1515.
