The purpose of this study was to compare student scores on geographic skills in the experimental group with student scores on geographic skills in the control group after adjustment was made in teaching methods and learning materials for verbal and spatial ability for students in the experimental group. Hypotheses tested at the .05 level were as follows. 1. Females would score higher than males on a criterion measure of verbal ability. 2. Males would score higher than females on a criterion measure of spatial ability. 3. Experimental/verbal students would score higher on a geography skills posttest. 4. Experimental/spatial students would score higher on a geography skills posttest. 5. The experimental group would score higher than the control group on a geography skills posttest. The sample was 150 high school United States History students in a medium-sized North Texas school district. Analysis of covariance was used to analyze results of the study of six classes after fifteen days of instruction in physical geography concepts. Experimental classes received geographic instruction directed to verbal and spatial abilities; control group classes received traditional geographic instruction which utilized textbook, lecture, and whole-group instruction. Three high schools participated in the study. Conclusions were that males and …
