Baby Steps, Professional Development, and Fun!: One administrator’s experience preparing a science department to infuse engineering into its science instruction. Over the past five years, I have slowly prepared my science department of 25 teachers to integrate engineering practices and content into their instruction. This work started due to the merger of our science and engineering programs at NNHS and has expanded due to the Framework for K-12 Science Education. During this workshop, I will provide an overview of the process, and then, participants will have the opportunity to take part in a number of the activities that we have done as a department including: a tuning protocol designed to identify opportunities for integrating engineering into existing science lessons; jigsaw protocols to examine the engineering components of the Framework for K-12 Science Education; and the Marshmallow Challenge, a structured conversation focused on the questions “What is science," "Why do we teach science," "What is engineering," and "Why do we teach engineering.” The “what next?” portion of the workshop will cover an introduction to the integration of engineering into the Next Generation Science Standards (and the Draft Revised MA Frameworks for Science and Technology/Engineering).
