Math anxiety has long been recognized to play a role in the math achievement of middle school and high school students (Hembree, 1990). Various studies have linked math anxiety to increased worries about math failure (Richardson & Woolfolk, 1980), to an avoidance of math and=or numerical tasks (Krinzinger, Kaufmann, & Willmes, 2009), and to an increased cortisol response when performing math ...

Abstract In this paper, we propose a new shape decomposition method, called convex shape decomposition. We formal-ize the convex decomposition problem as an integer linear programming problem, and obtain approximate optimal so-lution by minimizing the total cost of decomposition under some concavity constraints. Our method is based on Morse theory and combines information from multiple Morse ...
