The summer institutes incorporated effective components of professional development: long duration, focused content built on prior knowledge, active learning, community building, voluntary participation, and alignment with state and national science standards (Garet et al., 2001; National Academy of Sciences, 2005).
Additionally, they have tested variations of the STeLLA PD program including one that was of equal duration but focused on content deepening and did not include any video analysis work.
There are three types of tour: Rotational, aimed at entry-level employees, structured and of "finite duration"; Transformational, focused on completing a specific task and personalized to an individual employee; and the rarer Foundational tour, which is when an employee and employer want a lifelong link.
