While slides are commonly used to illustrate themes and concepts in re
gional geography courses, we argue that slide tests are also effective
tools to test students' understanding of these themes and concepts. A
fter briefly discussing the purpose for using slides, we check our cla
ssroom environment against visual screening standards. We outline proc
edures for testing with slides and generalize five pretest results. Th
en we consider the qualitative results derived from three formal exami
nations. Themes addressed in these examinations include wealth versus
poverty, language diversity, housing characteristics, transportation m
odes, deforestation, and the Panama Canal. We consider areas of visual
confusion and misinterpretation, and follow with suggestions for impr
oving slide set tests. Finally, we suggest implications for analysis o
f slides scanned into computers.
