In the Challenge-Based Learning (CBL) methodology, the Act phase is where research and planning transform into concrete action. After completing the Investigate phase, where students or teams explore a challenge in depth, the Act phase is dedicated to implementing solutions, testing their effectiveness, and refining them based on real-world feedback.

What Happens in the Act Phase?
The Act phase is structured around three key steps:
Developing and Implementing the Solution
This involves transforming the proposed solution into a tangible product, strategy, or intervention.
Teams apply their research findings from the Investigate phase to build and deploy their solution.
Testing and Evaluating the Solution
Solutions are tested in real-world conditions to assess their effectiveness.
Data is collected through observations, surveys, and feedback from stakeholders.
Adjustments and improvements are made based on results and performance metrics.
Reflecting on the Process
Participants analyze the successes and challenges encountered during implementation.
Reflection helps refine problem-solving skills and prepare for future iterations or scaling of the solution.
Why is the Act Phase Important?
The Act phase bridges the gap between theoretical knowledge and practical application. It fosters:
Critical thinking and problem-solving by requiring teams to adapt and refine their solutions based on real-world interactions.
Collaboration and communication through stakeholder engagement and teamwork.
Innovation and adaptability, as solutions evolve based on testing and feedback.
Real-world impact, as participants move from planning to making a tangible difference.
Looking Ahead
At the end of the Act phase, teams will have a tested and refined solution, along with valuable insights into how to approach real-world challenges effectively. This phase not only brings the learning experience full circle but also equips participants with essential skills for future problem-solving and innovation.
