This paper focuses on the use of scaling aspects for understanding transport processes with reaction in catalytic pores and pellets. The idea is to identify a systematic up-scaling approach in the learning process to help students with several concepts related to the transport-reaction process and the mathematical description associated with them.…

Discusses improvisation as a phenomenon. Offers suggestions for a learning sequence. Warns against allowing students to skip levels. Identifies developmental levels of improvisation as exploration, process-oriented, product-oriented, fluid, structural, stylistic, and personal improvisation. Urges that improvisation can and should be a meaningful…
