Dana-Picard, Thierry; Kidron, Ivy; Zeitoun, David – International Journal for Technology in Mathematics Education, 2008
The study of a real function of two real variables can be supported by visualisation using a Computer Algebra System (CAS). One type of constraint of the system is due to the algorithms implemented, yielding continuous approximations of the given function by interpolation. This often masks discontinuities of the given function and can provide very…

Affouf, Mahmoud; Walsh, Thomas P. – International Journal for Technology in Mathematics Education, 2007
The purpose of this study was to demonstrate the effectiveness of web-based homework (WBH) assignments on the overall comprehension measured by the final examination in a first year college algebra course. This study included 1653 students over a three year period. Results indicate a strong correlation between achievement on the WBH assignments…
