The purpose of this study was to evaluate the effects of science and technology summer camps on the confidence, values, and future intentions of female and male campers. The week-long camps were administered by Actua, a national organization with a mandate to increase awareness of science and technology among Canadian youth. Campers completed a survey both pre- and post-camp. Camps were perceived to be a very positive experience by 83% of campers. Significant positive changes were reported in confidence, values, and future intentions. Results provide some of the first quantitative evidence, at a national level, for the effectiveness of science and technology summer camps that use a hands-on, interactive approach.
