Teaching Integrated STEM in Middle School is a valuable resource for educators, researchers, and policymakers who are committed to furthering integrated STEM education. Through a review of the literature on the topic, the volume offers a clear understanding of the impact of integrated STEM education on instructors' teaching practices and student outcomes. The book presents a framework and instructional guide that educators can utilize to develop new curricular materials. Two sample units—focused on designing a two-stage water filter and formulating sunscreen—provide step-by-step guidance for lesson implementation and offer strategies for assisting students as they use engineering models to devise design solutions. Teaching Integrated STEM in Middle School also outlines future research directions that are essential for the advancement of integrated STEM education.
