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.…

Describes the application of basic factor analytical and classical scaling techniques to mathematics placement test data that indicates that the sequence of mathematical skill areas traditionally taught in schools should be somewhat altered in order for students to reach optimal achievement levels.
