Using both quantitative and
qualitative analyses, we will evaluate the hypotheses that: a) Classroom teachers can successfully and consistently integrate a CEMS approach in their algebra instruction, b) Students» procedural flexibility, procedural knowledge, and conceptual knowledge for a variety of algebra topics can be reliably assessed and each type of knowledge is positively related and
predictive of one another over time, and c) Integrating a CEMS approach supports better procedural flexibility, conceptual knowledge, and procedural knowledge for a variety of algebra topics (units) than business as usual instruction.
Indeed, the lack of agreement between the model's «hindcast» and actual temperatures since 1995 should remind us again to view this only as a very preliminary
analysis with
predictive ability that is much more
qualitative than quantitative.
