Gary S. Stager, Ph.D.

Since 1982, Dr. Gary Stager has helped school educators around the world embrace computational technology as an intellectual laboratory, vehicle for self-expression, and window onto a world of possibilities for amplifying the potential of each student in preparation for an uncertain future. All of his work is rooted in the Piagetian notion that “knowledge is a consequence of experience.” His activities with teachers and students are guided by a focus on learning-by-doing.

Gary is one of the world’s leading experts and advocates for computer programming, robotics and learning-by-doing in classrooms. In 1990, Dr. Stager led professional development in the world’s first laptop schools and played a major role in the early days of online education. In addition to being a popular keynote speaker at some of the world’s most prestigious education conferences, Gary is a journalist, teacher educator, consultant, professor, software developer, and school STEM. Director. An elementary teacher by training, he has taught students from preschool through doctoral studies.

Dr. Stager’s most recent book is Twenty Things to Do with a Computer Forward 50: Future Visions of Education Inspired by Seymour Papert and Cynthia Solomon’s Seminal Work.

When Jean Piaget wanted to better understand how children learn mathematics, he hired Seymour Papert. When Dr. Papert wanted to create a high-tech alternative learning environment for incarcerated at-risk teens, he hired Gary Stager. This work was the basis for Gary’s doctoral dissertation and documented Papert’s most-recent institutional research project.

Dr. Stager’s work earned a Ph.D. in Science and Mathematics Education and he collaborated on a project that won a Grammy Award. Recently, Gary was invited by Fondazione Reggio Children to lead a public seminars on education and teach students in Reggio Emilia, Italy.

Gary is on the advisory board of the NSF-funded project, BJC4NYC: Bringing a Rigorous Computer Science Principles Course to the Largest School System in the US and maintains the world’s largest archive of text and multimedia by Seymour Papert at The Daily Papert.

Gary is the founder of the Constructing Modern Knowledge Summer Institute for educators.
