Toward Designing and Developing Likert Items to Assess Mathematical Problem Solvingics courses. For future STEM majors, there is little debate over the procedural skills that are needed in algebra to continue in STEM, but what are the mathematical problem solving (MPS) skills needed to persist in calculus and beyond? There are currently few efficient tools that can be used to expl

Creating and Sustaining Online Problem Solving Forums: Two Perspectivesg in high school, by means of online problem-solving forums. We focus on two classroom communities and their interactions, during two school years, with an additional community, a research group that initiated the use of the forums. In one of the classroom communities, online problem solving has eve

The ARPA Experience in Chile: Problem Solving for Teachers’ Professional Developmentular teachers’ practice as a way of enriching mathematics classrooms, moving the attention from teacher to students and opening the route for developing abilities intertwined with content rather than content alone. Starting with the educational context in Chile, we describe the origin of the ARPA In

This paper is devoted to theoretical aspects of sparse approximation. The main motivation for the study of sparse approximation is that many real world signa

In 2000, Stefanie Petermichl discovered a representation formula for the venerable Hilbert transform as an average (over gr
