Introduction:
Sociology is a discipline that studies society and its various structures, institutions, and dynamics. It offers valuable insights into understanding societal issues and provides tools for addressing and solving them. Contemporary case studies can be used effectively to illustrate the relevance of sociology in solving societal issues by demonstrating the application of sociological theories and concepts in real-world contexts.

Key Pointers:
1. Understanding Social Inequality: Sociology provides a framework for understanding social inequality and its impact on society. Case studies that highlight issues such as income disparities, racial discrimination, and gender inequality can be analyzed using sociological theories like functionalism, conflict theory, or symbolic interactionism. These case studies can show how sociological perspectives help identify the root causes of inequality and suggest strategies for addressing them.

2. Exploring Social Change: Sociology examines the processes and factors that drive social change. Case studies that explore societal transformations, such as the impact of technology, globalization, or social movements, can be analyzed using sociological lenses. By studying these case studies, we can understand the role of sociology in predicting and managing social change, as well as its implications for various social groups.

3. Examining Social Institutions: Sociology examines various social institutions like family, education, and healthcare, and their role in shaping society. Case studies that focus on issues within these institutions, such as the changing dynamics of the modern family or the impact of education on social mobility, can demonstrate how sociology helps identify structural issues and propose solutions for better functioning institutions.

4. Analyzing Social Problems: Sociology helps in identifying and analyzing social problems like crime, poverty, and substance abuse. Case studies that discuss these issues in different contexts and societies can be used to apply sociological theories like strain theory, labeling theory, or social disorganization theory. By analyzing these case studies, we can gain insights into the social factors contributing to these problems and devise effective strategies for prevention and intervention.

5. Promoting Social Justice: Sociology is committed to promoting social justice and equality. Case studies that highlight social movements, advocacy work, or policy changes can demonstrate the role of sociology in challenging existing power structures and promoting positive social change. These case studies can inspire individuals to engage in activism and contribute to a more just and equitable society.

Conclusion:
Contemporary case studies provide real-world examples that illustrate the relevance of sociology in solving societal issues. By analyzing these cases using sociological theories and concepts, we can gain a deeper understanding of the root causes of social problems and develop effective strategies for addressing them. Sociology plays a crucial role in shaping policies, advocating for social justice, and promoting a more equitable society.
