The purpose of this study was to investigate the effect of graphic organizers on the academic achievement of high school students receiving instruction in United States History via an online blended learning environment. With 60 participants in the study, the students were equally divided into two groups of 30 participants each. Group I was designated as the treatment group, while Group II formed the control group. A two-tailed t-test was used to determine that the means of the two posttests were not significantly different at a probability level of .05. Therefore, the results of this research study indicated that high school students who received instruction in United States History in an online blended learning environment using graphic organizers did not perform significantly higher on the End-of-Course Test than high school students who did not receive instruction using graphic organizers.
