Margaret L NiessMargaret (Maggie) L. Niess is Professor Emeritus of Mathematics Education at Oregon State University. Her research focuses primarily on the knowledge teachers rely on for integrating technologies in teaching mathematics and science, otherwise called echnological Pedagogical Content Knowledge or TPACK. Her most recent book was Blended Online Learning and Instructional Design for TPACK: Emerging Research and Opportunities. She is currently co-principal investigator in a National Science Foundation grant titled: Child's Play: Learning Computer Science Through Tabletop Games. She has authored multiple peer-reviewed journals and chapters including multiple teacher preparation books. She directed the design, implementation, and evaluation of an online Master of Science degree program for inservice K-12 mathematics and science teachers with an interdisciplinary science, mathematics, and technology emphasis. Her research has identified an online learning trajectory framing student-centered instructional strategies using a social metacognitive constructivist context. She has chaired multiple committees for the Association of Mathematics Teacher Educators (AMTE's Technology Committee), American Educational Research Association's (AERA's SIG-TACTL called Technology as a Change Agent in Teaching and Learning), and the Society for Information Technology and Teacher Education (SITE's the Mathematics Education SIG and the Teacher Education SIG).
