The previous article reviewed the range of educational technology professional development session and program goals. In this article, the second part of four-part series, the author presents and explains educational technology-related professional development (ETPD) models. ETPD models can be classified into five general types of professional development, according to the kinds of professional learning that characterize each: (1) instructor-organized sessions (6 models); (2) individualized learning (4 models); (3) collaborative learning (5 models); (4) data-based inquiry (3 models); and (5) development of materials and approaches (2 models). Here, the author describes the range of ETPD models which makes clear how very differently ETPD sessions need to be designed, depending on the session and program goals that providers intend them to meet, which in turn are determined by participating teachers' learning needs and preferences. In Parts Three and Four, the author will address how to combine goals and models to fit particular teachers' characteristics, then assess the efficacy of those designs.
