This document provides an overview of Module 4 of Sociology 101 which will focus on different types of social interaction. It discusses Goffman's work on focused vs unfocused interactions and how expressions reveal interactions. It also outlines three reasons why the study of daily life is important to sociology: it reveals patterns of social behavior, how people creatively shape reality through interaction, and insights into larger social systems. The module will explore how new communication technologies impact social interaction and daily life. Students are assigned readings on social interaction and will complete activities and assessments on the topics covered.
