Preschool Education in the 21st Century – Innovative Insights, Strategies, and Practical Approaches explores early childhood teaching, learning, and learning to teach, focusing on young children and fostering the 4 C’s of 21st Century Learning: Collaboration, Critical Thinking, Creativity, and Communication. Early childhood teachers play a crucial role in building a strong foundation for all children’s future success—but it requires thoughtful, attentive, and developmentally appropriate approaches. In this volume, the authors bring unique perspectives from around the globe, including Japan, Nigeria, the United States, and Australia, as they explore the role of the teacher and ways to cultivate the 4 Cs that grow children’s understanding of the world around them. Through examples of high-quality, mindful, and compassionate approaches, the authors share lessons from the field and practical strategies and tools that early childhood educators can implement in their classrooms. Chapters explore inclusive practices that build 21st-century skills and future-ready learning environments. Innovative approaches to teaching and learning provide insights into the use of digital tools and technological practices in early childhood, including emerging technologies, and their impact on children’s learning. Particular attention is given to cultivating curiosity and critical thinking through integrating STEM—Science, Technology, Engineering, and Mathematics—into preschoolers’ classrooms, homes, and informal learning environments, while fostering STEM Habits of Mind. This volume offers ideas and insights for educators and researchers as the ever-changing world presents the field of early childhood with opportunities and challenges, including new ways to look at old problems. The authors in this volume think deeply and write thoughtfully about supporting the whole child in learning and growing. Readers will be inspired as they prepare early learners, and those who teach them, to be future-ready.
