Math anxiety is a common phenomenon which can have a negative impact on numerical and arithmetic performance. However, so far little is known about the underlying neurocognitive mechanisms. This mini review provides an overview of studies investigating the neural correlates of math anxiety which provide several hints regarding its influence on math performance: while behavioral studies mostly o...

Let $X$ be a vector space over a field $K$ of real or complex numbers. We will prove the superstability of the following Go{l}c{a}b-Schinzel type equation$$f(x+g(x)y)=f(x)f(y), x,yin X,$$where $f,g:Xrightarrow K$ are unknown functions (satisfying some assumptions). Then we generalize the superstability result for this equation with values in the field of complex numbers to the case of an arbitr...

Predicting Student Performance in Verbal Math Problems Based on Cognitive, Metacognitive, and Affective Factors F. Karimi, Ph.D. A.R. Moraadi, Ph.D. P. Kadivar, Ph.D. R. Kormi Noori, Ph.D. To determine the predictive role of metacognitive, cognitive, and affective factors in solving verbal math problems, a cluster sample of 450 junior high school  students was given ...

Jahanshahloo et al. (Appl Math Comput 153:215–224, 2004) propose a method for ranking extremely efficient decision making units (DMUs) in data envelopment analysis (DEA) using super-efficiency technique and l1-norm and they show that the presented method is able to eliminate the existing difficulties in some methods. This paper suggests an alternative transformation to convert the nonlinear mod...

With an aim to high-level understanding of the mathematical contents in a document image the requirement of math-zone extraction and recognition technique is obvious. In this paper we present fully auotmatic segmentation of displayed-math zones from the document image, using only the spatial layout information of math-formulas and equations, so as to help commercial OCR systems which cannot dis...

This full research-and-development project designs, develops and tests an interrelated system of technological, pedagogical and analytic components to provide a range of opportunities for middleand high-school students to engage in significant mathematical discourse (DR K-12 challenge 2); it catalyzes and supports these opportunities by enhancing the ability of in-service teachers to engage in,...
