This study examines African American students’ interactions with the graphing calculator as a tool to support their mathematical learning. Two participants, chosen through purposive sampling, were the focus of this study. The participants were presented with a task-based interview, and the strategies they employed in solving these tasks with the help of a graphing calculator were examined. The ...

The availability of technology has changed enormously during the last 20-30 years. From the large and clumsy desk calculators of the 1970’s over to the so called functional calculators in the 1980’s and during the last 10-15 years we have got graphing calculators as well as symbolic calculators. There are also calculators which include software for geometrical constructions on the market today....

This thesis describes a method for computationally recognizing the geometrical interpretation of most blades of the model of projective line geometry in geometric algebra. These different interpretations are not merely recognizable by the grade of the elements, or the absence or presence of some basis vector, as can be done for the homogeneous model for geometric algebra. GAViewer, a graphical ...

a graph g is said to have a totally magic cordial labeling with constant c if there exists a mapping f : v (g) ∪ e(g) → {0, 1} such that f(a) + f(b) + f(ab) ≡ c (mod 2) for all ab ∈ e(g) and |nf (0) − nf (1)| ≤ 1, where nf (i) (i = 0, 1) is the sum of the number of vertices and edges with label i. in this paper, we give a necessary condition for an odd graph to be not totally magic cordial and ...

mean labelings are a type of additive vertex labeling. this labeling assigns non-negative integers to the vertices of a graph in such a way that all edge-weights are different, where the weight of an edge is defined as the mean of the end-vertex labels rounded up to the nearest integer. in this paper we focus on mean labelings of some graphs that are the result of the corona operation. in parti...

Algebra is a very important topic in mathematical programs for upper secondary education, but a vast majority of students is weak in understanding and using formal algebraic tools. This paper discusses some ideas about using the graphing calculator to support the learning of algebra in the context of functions and to help students overcome algebra-anxiety. Accepting the graphing calculator as a...
