A Course-Based Teaching Experience for STEM Undergraduates Improves Student Perceptions of Teaching Self-Efficacy and Attitudes Toward Teaching Careers.

The Learn By Doing Lab is a course in which STEM undergraduates teach hands-on life science and physical science to local third- through eighth-grade schoolchildren visiting the campus.
