This study investigated the use of art lessons to enhance the comprehension of specific concepts taught in a school curriculum. Reading and mathematics achievement measures were administered as pre- and posttests to 87 fifth graders. Students in the treatment group were taught art lessons by an art teacher. In these lessons, the concepts of area, volume, perimeter, congruency, pattern, and sequence were stressed. Students in the comparison group were taught these concepts by their classroom teachers during the regular mathematics and reading periods. Results indicated that students in the treatment group exhibited significantly higher mean posttest scores for the concepts of pattern and area, and combined posttest scores across the six concepts, than students in the comparison group. For all concepts except perimeter, students in the treatment group showed a greater gain than students in the comparison group in test scores between pre- and posttest. A 33-item reference list is provided. Sample lessons that use art in the teaching of concepts are appended. (BC)
