Spring Semester 2016
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 was 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 Allianceand the Georgia Center for Advanced Telecommunications Technology.

Some Papers
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.
