EDU-STEM is Equity and Diversity in Undergraduate Science, Technology, Engineering and Mathematics (STEM), a network funded by the National Science Foundation to support the research-coordination efforts of those interested in equitable teaching practices in introductory biology. The EDU-STEM network is a sustained multi-institutional education research and implementation research-coordination network, initially centering on introductory biology. This network is motivated by a focus on equity and inclusion in large introductory biology courses.
