This book is divided into six chapters that examine opportunities, perspectives, and challenges in a variety of school environments. The first chapter investigates Catholic schools from the perspectives of Catholic school leaders. Chapter Two is a quantitative study, which explores the relationship between teaching characteristics of primary grade schoolteachers, such as teaching length, number of pupils, monthly income, frequency of seminar participation, and teaching style with their knowledge, attitude, and practices (KAP) on free play. In Chapter Three the author investigates potential underlying causes of the pervasive issues in American public education: high teacher attrition, shortages, low efficacy, and student academic regression. Chapter Four is a quantitative examination of enrollment data from Ohio's three largest voucher-based religious private schools based on racial diversity. In Chapter Five, the authors evaluate a new online training course on risk assessment and indoor microenvironments offered to New Jersey Career-Technical Education students during COVID-19. In the last chapter, the authors address the challenges that, although public school is free and available to all children, it is not equal for all.
