This article examined six theory- and practice-based elements of instructional learning design in online teacher professional development (oTPD), how these elements were implemented into Edinger's PACKaGE model of gifted education oTPD, and how teachers evaluated each element. Elements were based on Berge's (1995) instructor roles model theory and gifted education research. Each element was evaluated by teachers (N = 184) who completed oTPD designed from the PACKaGE model. Self-report survey findings suggest that teachers considered most elements, such as asynchronous discussion board and article review assignments, to be useful to a great extent to their gifted education learning and pedagogy. However, teachers reported less usefulness for the online group project element. This finding directly contrasts with researchers' suggestions for oTPD. These findings may encourage teachers to choose theory- and research-based oTPD. PD designers can investigate and implement oTPD elements that satisfy instructional design model needs for optimal teacher learning and gifted education pedagogy.
