In this seminar-style course, we will discuss classic and recent findings in the “science of learning”, drawing on fields ranging from cognitive psychology and education to cognitive neuroscience and neurobiology.
We will read primary sources and discuss them each week.
We will also embrace the idea that effective learning in the sciences (as in all fields) requires effective communication, whether in research papers, course lectures, or presentations to non-scientific audiences.
We will critically evaluate best communication practices for different media, venues, and audiences in light of research on the science of learning.

SLAC Outreach Seminar, Spring (1 credit)
This course provides hands-on training in communicating research-related topics to local populations (children in a K-8 setting, retirement communities).
Initial in-class meetings will provide an overview of potential local venues (schools, community forums), and feedback about calibrating presentations for children, interested lay public groups, etc.
Through the semester, we will meet periodically to assess progress, discuss course materials, practice the presentations that students develop, and provide feedback on these presentations.
