• Programming: Gain hands-on experience with programming languages such as Python, Java, or C++. Learn basic programming constructs like variables, control structures (loops and conditionals), functions, and classes.

• Problem-solving: Develop problem-solving skills through practice and exposure to various computational problems. Learn techniques such as divide and conquer, dynamic programming, and greedy algorithms to tackle complex problems effectively.

 

• Computational Thinking: Cultivate computational thinking skills, which involve breaking down problems into smaller, manageable parts, identifying patterns, and designing algorithms to solve them. Understand how computational thinking applies to various domains beyond computer science.

 

• Software Engineering Principles: Explore principles and best practices of software engineering, including modular design, code reuse, testing, debugging, and version control. Learn how to write clean, maintainable, and scalable code.

 

• Ethical and Social Implications: Consider the ethical and social implications of computing technologies. Discuss topics such as privacy, security, intellectual property, accessibility, and the impact of technology on society.

 

Throughout the course, students will engage in lectures, hands-on exercises, coding assignments, and projects to reinforce their understanding of the material. By the end of the course, participants will have gained a solid foundation in computer science principles and will be better equipped to pursue further studies or careers in the field.

 

2. Justice: The exploration of ethical and moral philosophy through the lens of justice is a profound and multifaceted journey that delves into critical questions about the nature of fairness, equality, and the responsibilities individuals and societies have towards one another. This course encompasses both historical and contemporary perspectives, allowing students to understand how ideas about justice have evolved over time and how they continue to shape our societies today.

 

• Foundations of Justice: The course begins by examining foundational theories of justice proposed by philosophers throughout history. This includes a study of classical theories such as utilitarianism, deontology, and virtue ethics, as well as more modern approaches like John Rawls’ theory of justice as fairness.

 

• Equality and Equity: One of the central themes explored in the course is the distinction

 

between equality and equity. Students investigate questions such as: What does it mean for a society to be just? Is it enough for everyone to be treated equally, or does justice require addressing systemic inequalities and providing equitable opportunities for all?

 

• Social Contract and Obligations: The concept of the social contract is examined in depth, exploring the idea that individuals enter into a mutual agreement with society to uphold certain rights and obligations. Students analyze the implications of this contract for issues such as distributive justice, criminal justice, and the role of government in ensuring fairness and order.

 

 

• Justice and Diversity: The course also considers how notions of justice intersect with issues of diversity, identity, and cultural pluralism. Students explore questions such as: How should justice be understood in multicultural societies? What obligations do individuals and institutions have towards marginalized groups?

 

• Justice in Practice: Drawing upon real-world examples and case studies, students examine how theories of justice are applied in practice. This includes analyzing legal systems, social policies, and international frameworks for promoting justice and human rights.

 

• Contemporary Debates: Finally, the course engages students in contemporary debates surrounding justice, such as debates about economic inequality, environmental justice, global poverty, and social justice movements. Students are encouraged to critically evaluate different perspectives and develop their own informed opinions on these complex issues.

 

Throughout the course, students are challenged to think critically, engage in rigorous ethical reasoning, and consider the practical implications of different theories of justice for individuals and societies. By the end of the course, students gain a deeper understanding of the complexities of justice and are better equipped to contribute to informed discussions and decision-making in their personal and professional lives.
