This study investigated whether the instruction of visualdesignprinciples had an influence on pre-serviceteachers’ perception and analysis (interpretation) of visual materials. In addition, the relationships between pre-serviceteachers’ visual intelligence and their perception and analysis (interpretation) of visual materials were also explored. Participants were 86 pre-serviceteachers who took a one-credit required educational technology course at a mid-western university in the United States. Some participants were absent in the weeks when data were collected, resulting in a total of 59 responses included in data analysis. Findings implied that the instruction of visualdesignprinciples could possibly improve pre-serviceteachers’ visualliteracy. Suggestions for future research were discussed.
