To date, there remains limited knowledge about the cognitive, motivational and psychological impact of the COVID-19 global pandemic on learners across all developmental levels. This book seeks to explore the impact of the COVID-19 global pandemic on high school, undergraduate and graduate-level learners around the world. This research has been conducted in multiple countries, across multiple continents, using multiple diverse populations, using several different research methodologies, along with an emphasis on both the challenges as well as the positive outcomes that have resulted from this unprecedented event, the COVID-19 global pandemic. The concluding chapter serves to synthesize this diverse research into the effects of the pandemic on high school, undergraduate and graduate learners. Specifically, this thematic conclusion elucidates the effects of the COVID-19 global pandemic on: learner socialization, mental health and well-being, self-regulated learning, autonomy and responsibility, the experiences of underrepresented and underserved learners, technology, and familial experiences.
