He received his B.S. in Mechanical Engineering and Ph.D. in Engineering Education (both at Tufts University). In his research, Hynes explores the use of engineering to integrate academic subjects in K-12 classrooms. From close observations of classroom teaching and learning, he studies how students come to understand what engineering is and how learners conceptualize and engage in engineering and design. Specific research interests include design metacognition among learners of all ages; the knowledge base for teaching K-12 STEM through engineering; broadening the contexts of engineering activities to broaden participation and engagement; and teaching engineering. He has worked with a number of Boston Public Schools in integrating engineering activities into their curriculum.
