Technology use in mathematics often involves either exploratory or expressive modeling. When using exploratory models, students use technology to investigate a premade expert model of some phenomena. When creating expressive models, students have greater flexibility for constructing their own model for investigation using objects and mechanisms…

Discusses representations in the context of solving a system of linear equations. Views representations (concrete, tables, graphs, algebraic, matrices) from perspectives of understanding, technology, generalization, exact versus approximate solution, and learning style. (KHR)

The Center for Improved Engineering and Science Education (CIESE) at Stevens Institute of Technology helps mathematics teachers to integrate and implement engaging and innovative collaborative lessons into their curriculum for illustrating complex mathematics concepts. CIESE has developed online projects that incorporate complex mathematics…
