Summer Enrichment Workshop (SEW) is a 3-week enrichment program held at The University of Alabama (UA) Tuscaloosa, Alabama, for students identified as gifted and talented. The faculty of the College of Education, Program of Gifted and Talented (GT), formed a partnership with a College of Engineering faculty member who mentored the graduate student GT interns to develop and teach middle school science minicourses in the SEW program. Data indicate that the challenge level of the science middle school minicourses improved, and interns experienced more competence and confidence in teaching upper-level science courses. Contributing factors included having a science expert to collaborate in planning content and coteaching lessons; consistent reflection on practice; making learning more real-world; providing support, assistance, guidance, and counseling; long-term planning; problem solving and inquiry; and experimentation and risk taking, followed by immediate corrective feedback.
