Rick Ginsberg and Yong Zhao want educators to question the status quo and clear out ineffective practices to make room for K-12 reforms that work. Their 2023 book, Duck and Cover: Confronting Dubious Practices in Education, Ginsberg and Zhao examine kindergarten readiness, college- and career-readiness, reading proficiency by 3rd grade, social and emotional learning, education technology, class size, dress codes, state standardized testing, meta-analysis, and more.
