Eighty-two students enrolled in a regular World History course were purposefully selected and assigned to 1 of 4 groups: (a) Highlight, (b) Animation, (c) Highlight-and-Animation, or (d) Comparison. A One-Way ANCOVA with a Bonferroni Adjusted Alpha was used in analyzing the results of the knowledge and comprehension World History pretest and posttest that were administered. A Factorial ANCOVA with a Bonferroni Adjusted Alpha was used in analyzing the influence of the Scholastic Reading Inventory (SRI) moderator. Using the eEdition World History textbook tools of highlight and animation did not significantly impact the World History knowledge and comprehension scores achieved by participants and the participant's SRI level did not significantly moderate the relative effectiveness of the conditions.
