This presentation was developed as part of the course Introduction to Sociology taught at the American University of Technology. The lecture materials are based primarily on the conceptual framework and theoretical foundations presented in the 17th edition of Introduction to Sociology by John J. Macionis. The presentation introduces students to the basic principles, concepts, and analytical perspectives of sociology, including the sociological imagination, social structure, culture, institutions, and patterns of social interaction. The materials are designed to facilitate students’ understanding of key sociological theories and to encourage critical analysis of social phenomena in contemporary societies. The lecture slides were prepared for undergraduate teaching and aim to provide a structured overview of the discipline while integrating theoretical explanations with illustrative examples relevant to modern social contexts.
