Abstract
Caution marks and accompanying notes were extracted from 22 junior high school technology
and home economics textbooks from three different publishers in order to compare shapes, colors,
and verbal expressions by publication year, school type, and publisher. The results indicated that
caution marks and notes varied from textbook to textbook, and that there was no uniformity among
the different school types or publishers. In order to emphasize the ideas of safety and caution, and
effectively alert students, it is suggested that general caution marks be standardized and that uniform
guidelines on caution marks be used in textbooks.
