1. The Florida State University (FSU) Computer Science Integrated with Mathematics in Middle Schools (CSIMMS) project explores the feasibility and effectiveness of integrating Computer Science (CS) into middle school general mathematics courses. Through Design Based Research, we developed and tested 13 teaching modules that integrate CS concepts into general middle school mathematics courses, grades 6, 7, and 8, beginning in 2017. In this paper, we discuss our experience with integrating computer science into middle school mathematics and report our preliminary findings.

Systems of linear equations (SLE) comprise a fundamental concept in linear algebra, but there is little research regarding the teaching and learning of SLE, especially students' conceptions of solutions. In this study, we examine students’ understanding of solutions to SLE in the context of an experientially real task sequence. We interviewed two undergraduate mathematics majors, 3 who were also preservice teachers, to see how they thought about solutions to SLE, especially linear systems with multiple solutions. We found participants used their knowledge of SLE in two dimensions to think about systems in higher dimensions, sometimes ran into algebraic complications, andmore »

In this paper, we introduce an RME-based (Freudenthal, 1991) task sequence intended to support the guided reinvention of the linear algebra topic of vector spaces. We also share the results of a paired teaching experiment (Steffe & Thompson, 2000) with two students. The results show how students can leverage their work in the problem context to develop more general notions of Null Space. This work informs further revisions to the task statements for using these materials in a whole-class setting.
