Functional Algebra with the use of the Graphing Calculator

Developing an Online Function Reader

A function reader is a program that can read an input function and evaluate the function for a given input value at run time. Any Computer Algebra System and Graphing Calculator are function readers. Evaluation of a given function is often done by using a function reader. However, any Computer Algebra System or Graphing Calculator is costly. As the world is connected by the Internet, would that...

The Impact of Graphing Calculators on Student Performance in Beginning Algebra

The Microsoft Word Free Mathematics Add-In and Microsoft Mathematics Beta 4.0

This paper explores the use of powerful, free computer algebra system (CAS) software for the K-12 and university science, technology, engineering and mathematics (STEM) classrooms. Educational institutions are sorely in need of affordable technology. The financial reality facing many schools prohibits the allocation of limited resources for appropriate mathematical software. The free mathematic...

Visualization of the projective line geometry for geometric algebra Drawing lines in GAViewer

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 ...

Algebra and technology: Emerging issues*

Synopsis: Although there are a number of technologies related to school algebra, it is only the personal technology of the graphics calculator that seems likely to be available widely enough to influence curriculum design and implementation on a large scale. The algebra curriculum of the past is overburdened with symbolic manipulation at the expense of understanding for most students. But algeb...
