This book brings readers into classrooms and communities to explore critical curriculum issues in the United States throughout the twentieth century by focusing in on the voices of teachers, administrators, students, and families. Framed by an enduring question about curriculum, each chapter begins with an essay briefly reviewing the history of topics such as student resistance, sociopolitical and culturally-centered curricula, curriculum choice, the place and space of curriculum, linguistic policies for sustaining cultural heritages, and grading and assessment. Multiple archival sources follow each essay, which allow readers to directly engage with educators and others in the past. This promotes an in-depth historical analysis of contemporary issues on teaching for social justice in the fields of curriculum studies and curriculum history. As such, this book considers educators in the past—their struggles, successes, and daily work—to help current teachers develop more historicallyconscious practices in formal and informal education settings.
