Full Challenge: The number of professional development opportunities for PK-12 teachers that focus on how to engage students in active STEM learning experiences.

Challenge Description: Teachers often lack professional development opportunities that enable them to design and deliver active STEM learning experiences for their students. Active STEM learning experiences are those that enable students to construct their own understanding; build on the ideas, experiences, and questions that students bring to the classroom; are grounded in real-world problems; and engage students in hands-on and collaborative learning.
