Electronic Theses and Dissertations
The mechanism of RAPRENOx reactions - RAPid REduction of Nitrogen Oxides using Isocyanic acid - proposed by Robert A. Perry1 in an attempt to help control the emission of nitrogen oxides pollutant into the atmosphere, has been re-investigated theoretically. The study of reaction mechanisms was carried out using Chemist software2. All mathematically possible elementary steps have been evaluated and the chemically reasonable ones have been considered to propose new sets of reaction mechanisms. Density Functional Theory (B3LYP/6-31 G**) calculations using Gaussian 983 were made in order to study the relative energies of all species and …

Grading The General Chemistry Laboratory: A Constructivist Approach., Barbara Stewart
Electronic Theses and Dissertations
Constructivist theories of learning posit that instructors cannot transfer their knowledge to students; students must actively construct their own understanding. The Inter-Chem-Net project uses technology and instrumentation to provide an individualized experience within the large general laboratory course, effectively establishing a constructivist methodology. A grading rubric was developed to communicate course expectations and provide an easy and reliable method of evaluating student work in the general chemistry laboratory. The grading rubric separates the learning outcomes into a checklist of skills associated with each particular grade. This checklist provides detailed feedback for individualized choices of experiments, a key component of the …
