Use of interactive whiteboards (IWBs) in school classrooms and conference rooms is increasing. To evaluate the effectiveness of IWBs as a tool for Extension education, two groups of 3rd and 4th grade Minnesota students (n=325) were taught nutrition using traditional methods or IWBs. Significant increases in knowledge and behavior were observed in both groups after the lessons, with no differences observed between groups. Teachers and Extension staff were generally positive about using IWBs to teach nutrition. The results indicate IWBs can be effective when used for Extension nutrition education in schools.
