Color, texture, line, shape, and form are just some of the words the author's students learn as they study the environment around them.

The "relativist"…

This experimental investigation replicates previous investigations of the effects of left margin screen background color hue to signal lesson sections on declarative knowledge and extends those investigations by adding a measure of structural knowledge. Participants (N = 80) were randomly assigned to receive 1 of 4 computer-based lesson treatments…
