Resumen de The Effects of a Two-Year Molecular Visualization Experience on Teachers' Attitudes, Content Knowledge, and Spatial Ability.

Vickie M. Williamson, Thomas J. José

• This study measures changes in teachers' attitudes, content knowledge, and spatial ability following a two-year visualization workshop experience. The workshop involved intensive, half-day sessions over three weeks for two consecutive summers, in which the participants worked with three-dimensional models and computer-generated images. No changes were observed in content knowledge and only a few significant changes in attitude were found. However, this study did find that throughout the workshop teachers' spatial abilities significantly increased with use and decreased with lack of use.
