Abstract

This study was a quasi-experimental trials that compared relative effectiveness of Infographics Based Reusable Learning Objects Educational Intervention (RLO and Traditional Didactic Lectures (TDL). A total of 282 Clemson university students were randomized into four groups – Control, RLD, TDL and RLO+TDL and changes in their pre-test and post-test scores were compared before and after each interventions. Specific outcomes tracked included the number of correctly recognized symbols identifying a type plastic, the number of correctly answered question about the safety of using plastic food containers in a microwave and the satisfaction with the instruction. The analysis suggests that RLO intervention was more effective than TDL, for improving symbol recognition and for improving health perceptions of plastic food containers. In addition, satisfaction with RLO was higher than with TDL by ∆M = 1.04 points t (119) = 15.1, p < 0.01.
