Describes a system to construct paper models of all 51 of the possible fullerene isomers from C60 through C84. Provides students, teachers, and specialists with an inexpensive mechanism to follow the literature interplay on fullerene structures. (JRH)

Describes ways that students can explore mathematical connections through the travels of Geo-dolls. (Contains 12 references.) (Author)

Uses base-ten manipulative pieces to illustrate divisibility tests with single-digit divisors. (YDS)

Describes a lesson on long division using chip trading which follows that algorithm for long division. (MKR)

Shows how geometric truths can be reinforced by simple exercises with lines and dots. (MKR)

The child's attention, how this attention is reasoned about, and how attention works as a surface for pedagogical intervention are central to understanding modern schooling. This article examines attention as an object of knowledge related to the organization and management of individuals. I address what we might learn about attention by studying…

This study evaluated the relative suitability of a range of base materials for producing tactile maps and diagrams via a new ink-jet process. The visually impaired and sighted participants tactilely scanned arrays of symbols that were printed on seven substrate materials, including paper, plastic, and aluminum. In general, the rougher substrates…

Katrina is 10 years old and has Down syndrome. She is making good progress with learning numbers and mathematics. We describe how Katrina has learned number concepts and arithmetic skills over several years. We highlight the influence of early learning habits, visual supports, motivation and practice, and the uses made of different number…

This Action Research Project is meant to investigate the effects of incorporating research-based instructional strategies into instruction and their subsequent effect on student achievement in the area of problem-solving. The two specific strategies utilized are the integration of manipulatives and increased social interaction on a regular basis.…

Responding to the concern from our faculty that undergraduate students do not have robust laboratory skills, we designed and implemented a strategy to individually teach and assess the manipulative skills of students in first-year laboratories. Five core laboratory skills were selected for the course entitled Human Biology, a large, first-year…

Judge Harry T. Roman, an electrical engineer and inventor, has selected the best of the crop in the 2006/2007 Tech Directions Inventors Award Competition. The challenge this year called on students to slow the filling of landfills by devising uses for discarded plastic water, juice, soda, and sports-drink bottles. Judge Roman noted "many common…

The basics of the metric system are explained, and the materials a teacher will need to instruct students in metrics are described. (JD)

Describes the work in one area (functions) of an experimental project in mathematics involving the same group of children from kindergarten through second grade. The project was undertaken chiefly to give mathematical continuity to activities that made use of manipulative aids. (BR)
