Technology and Secondary School Mathematics
This is the web site page devoted to EMAT 4680/6680 Technology and Secondary
School Mathematics at the University of Georgia as led by Jim Wilson. The
development of this course has been assisted by my involvement in the Learning and Performance Support Laboratory, University of Georgia. A little support was
provided from grants GRA/GCATT94.02 and GRA/GCATT94.03 of the Georgia Research Alliance and the Georgia Center for Advanced
Telecommunications Technology.

Roots
2 and 5. This paper examines sets
of equations that have graphs crossing the x-axis only at 2 and 5. For a
preview on one family of such graphs, click here.
Exploration
of a Triangle Ratios Problem. Given a triangle ABC and an interior point M. Extend
a segment from each vertex through M to its intersecion with the opposite side
creating segments AD, BE, and CF. The exploration will evaluate some ratios of
segments within the triangle.
