A new article called "Animating an equation: a guide to using FLASH in mathematics education" has recently been published in International Journal of Mathematical Education in Science and Technology. The article is written by Ezzat G. Bakhoum. Here is the abstract of the article:
Macromedia's FLASH development system can be a great tool for mathematics education. This article presents detailed Flash tutorials that were developed and taught by the author to a group of mathematics professors in a summer course in 2005. The objective was to educate the teachers in the techniques of animating equations and mathematical concepts in Flash. The course was followed by a 2-year study to assess the acceptance of the technology by the teachers and to gauge its effectiveness in improving the quality of mathematics education. The results of that 2-year study are also reported here.
