This chapter presented three principles from cognitive psychology to explain some misconceptions and misrepresentations of constructivism and brain-based education. These principles were then translated into five recommended action steps that addressed teachers' needs to identify and articulate the specifics of content, to ensure that students have multiple exposures to content, to identify procedures to be mastered, to structure content and tasks using the principle of sameness, and to engage students in complex tasks that require them to address content in unique ways.
