Challenge Based Learning (CBL) provides an efficient and effective framework for learning while solving authentic Challenges. The framework is collaborative and hands-on, asking all participants (students, teachers, families, and community members) to identify Big Ideas, ask good questions, discover and solve Challenges, gain in-depth subject area knowledge, develop 21st-century skills, and share their ideas.
The longer duration of a Mini Challenge (2–4 weeks) allows for more in-depth research and reach of Solutions. Taking a “show me what you can do” perspective, Mini Challenges are good for intense learning experiences that stretch the Learners and can be used to prepare Learners for Macro Challenges.
The CBL Framework is divided into three interconnected phases: Engage, Investigate, and Act. Each phase includes activities that prepare the Learners to move on to the next stage. The Nano Challenge follows this general framework but shortens and simplifies the process.
Through a process of Essential Questioning, the Learners move from an abstract Big Idea to a concrete and actionable Challenge.
All Learners plan and participate in a learning journey that builds the foundation for Solutions and addresses curriculum requirements and personal interests.
Evidence-based Solutions are developed, implemented with an authentic audience, and then evaluated based on their results.
Throughout the Challenge, Learners document their experience using audio, video, images, and photography. The ongoing collection of content provides the resources for reflection, informative assessment, and documentation of the learning process.
There are two pathways toward earning this micro-credential:
It is highly recommended that you use the CBL tracking matrix and/or canvas available at
This section lists the items you must submit to earn this micro-credential and the criteria by which they will be evaluated. To earn this micro-credential, you must receive a passing evaluation for Parts 1 and 3, and a “Yes” for each component of Part 2.
(200-word limit for each response)
Submit two personal, peer, or student examples that demonstrate an understanding of each phase of CBL. These can be submitted using the CBL matrix or canvas and can contain links to exemplar presentations, diagrams, or videos. The experience will be evaluated using the following rubric.
Provide a reflection on what you, your peers, or students learned, using the following questions as a guide (200-word limit):
