With the underrepresentation of minority students in science, technology, engineering, and mathematics (STEM) related fields, it is important for us to develop ways to narrow this gap. This study examines the use of LEGO robotics to increase the interest and motivation of children, particularly Hispanic and African-American students. Participants were fifth graders from two low SES schools attending an after-school robotics program. Students were randomly assigned either learning science in the traditional classroom setting or learning science with robotics. The results from this study found that learning with LEGO robotics can increase minority students' interest and motivation in science and technology.
