College students in a teacher education program of study typically take one or more courses in psychology. An important reason for this is that an understanding of psychology helps one to understand people—in particular, one’s students, their parents, and fellow educators.
One of my favorite forms of self-education and entertainment is to view Technology, Entertainment and Design (TED) Talks (TED, 2017). These videos are typically under 18 minutes in length and the speakers are well-qualified in their presentation areas.
