Dive into the most pressing global challenges of our time through the power of debate! This dynamic course empowers students to become effective advocates for the United Nations Sustainable Development Goals (SDGs), exploring critical issues from climate action and poverty to sustainable cities and gender equality.

Each session will focus on a new SDG-related topic, challenging students to research diverse perspectives, construct logical arguments, and present compelling cases. We will utilize a collaborative, team-based debate format (two teams of five students each) that ensures active participation and fosters teamwork.

What You'll Learn & Develop:

Deep Understanding of SDGs: Gain in-depth knowledge of the 17 Sustainable Development Goals and their real-world complexities.

Critical Research Skills: Learn to identify credible sources, gather compelling evidence, and analyze complex information.

Logical Argumentation: Master the art of building structured, persuasive arguments and identifying flaws in opposing viewpoints.

Effective Communication: Enhance your public speaking, clarity, and articulation skills through regular debate practice.

Collaborative Teamwork: Work effectively in a team, strategizing and synthesizing arguments to achieve a common goal.

Global Awareness & Advocacy: Develop a stronger voice to advocate for positive change in your community and on the global stage

Each week, students will receive a "Debate Briefing Document" outlining the upcoming SDG topic, resolution, and key research areas. During our live sessions, teams will finalize their arguments, engage in structured debates, and receive constructive feedback to continually refine their skills.

Join us to sharpen your mind, find your voice, and contribute to a more sustainable future!

Target Audience: Students (ages 12-18)
