Responding to the linguistic and cultural diversity of the U.S. K-12 student population and an increasing emphasis on STEM, this book offers a model for professional development that engages teachers in transformative action research projects and explicitly links literacy to mathematics and science curriculum through sociocultural principles. Providing detailed and meaningful demonstrations of participatory action research in the classroom, Razfar and Troiano present an effective, systemic approach that helps preservice teachers support students' funds of knowledge. By featuring teacher and researcher narratives, this book centers teacher expertise and offers a more holistic and humanistic understanding of authentic and empathetic teaching. Focusing on integrating instructional knowledge from ESL, bilingual, and STEM education, the range of cases and examples will allow readers to implement action research projects in their own classrooms. Chapters include discussion questions and additional resources for students, researchers, and educators.
