Cognitive Scientists from Educational Testing Service will aid development of a Logic Model/Theory of Action for teaching and learning in the Algebra Project. The goal is to develop a theory of action and logic model that reflects the successful teaching and learning with the instructional materials that the project has used during the National Science Foundation’s DRK-12 award to prepare low performing high students to graduate on time and be ready to take college mathematics courses for credit. This model can also guide future research and product development. Development of a report/paper for submission to mathematics education and education policy journals would provide an important contribution to the literature on working with students who have not been reached with current approaches. The NSF is providing a $45,000 supplemental award for this effort.
