The purpose of the present study was to evaluate the online delivery of an affective curriculum for gifted and talented youth to gain further understanding of its effectiveness and perceived advantages and disadvantages of delivering affective curriculum online. Using convergent parallel mixed-methods design, we evaluated data from 38 secondary education students and 4 camp counselors to examine their experiences with the online delivery of an affective curriculum. We found the curriculum effectively increased students' self-perceptions, planning, and self-monitoring. Further, camp counselors generally perceived the online delivery to be effective and identified several benefits of online delivery, such as increased access and easier differentiating. Yet, they continued to prefer a face-to-face delivery where possible. Implications for practice are discussed.
