This book consists of seven chapters, each providing a different point of view on the topic of critical thinking, which is defined as the analysis of facts to form a judgment. Chapter One aims to develop a method for improving students' critical thinking skills using cooperative learning. Chapter Two focuses on an education program designed to develop students' creativity and critical thinking skills and the impact this program had on teachers in Portuguese public schools. Chapter Three discusses the methods of teaching critical thinking that are most suitable for the Russian educational community. Chapter Four analyzes the importance of critical thinking skills for fighting misinformation in the context of the COVID-19 pandemic, around which many unscientific rumors and conspiracy theories are propagated alongside truthful information. Chapter Five also concerns the COVID-19 pandemic, specifically in connection with the natural human bias towards optimism and how this bias distorts risk assessment in health-related decisions but also provides a sense of control and hope. Chapter Six discusses how teachers can leverage Donald Trump's proclivity towards manipulative rhetoric, glaring fallacies, and conspiracy theories for teaching critical thinking skills, as well as the potential pitfalls of doing so. Finally, Chapter Seven aims to rethink Essential Learning Outcomes by examining what skills are valued by employers and proposes a strategy of cross-listing courses to facilitate skill acquisition across disciplines.
