I had the pleasure of introducing science, technology, engineering, and math (STEM) practices and content to York County Head Start teachers this past September. During the day-long STEM teacher training workshop teachers were introduced to foundational principles of STEM and STEM content appropriate for young children. We started off the day with incorporating reflective journaling in the early childhood classroom. We then headed outdoors, teachers learned how to use the schoolyard and building areas to introduce and reinforce STEM practices and content. From journaling, to using technology and tools, finding patterns and shapes, architecture, and nature of matter. Teachers were introduced to : developing lessons that develop and strengthen 21st century skills, engineering design process, technology and tools to use within the early childhood classroom, how to incorporate STEM practices within the Block Center, exploring shapes and geometry, building ramps and much more. It was a great group of teachers, they left the day-long introductory STEM teacher training workshop excited, and ready to begin implementing STEM practices and content within their early childhood classrooms. The following photos are a sample of the STEM explorations conducted during the training.
