This book is tailored for undergraduate students taking the Critical Thinking courses in universities. The book starts with a brief introduction on the Critical Thinking concept and the barriers to thinking critically. Then, the chapter progresses to recognising and evaluating arguments, the types of fallacies, and how to detect fallacies in communication as well as in media. Class activities provided throughout the book are aimed for students to test their comprehension of the topics and to practise what they have learnt. Margin notes containing interesting and valuable information are interspersed throughout the chapters for quick reference. Review and Discussion Questions, Case Studies, and Critical Thinking Questions at the end of each chapter serve to encourage students to think critically and promote their confidence by justifying their points of view in group discussions.
