What is problem-based learning?
It is a teaching approach in which students build knowledge by investigating an authentic, open-ended problem rather than memorising an answer before applying it. Learners identify what they need to know, test ideas, explain decisions, and refine solutions while the teacher guides the process. Saval delivers this approach through structured scenario challenges that can be answered with text, code, images, matching tasks, or selected responses. Teachers define the rubric and assessment settings, then use AI grading and live classroom views to check understanding as the lesson unfolds. This makes PBL practical for both K-12 schools and university courses without reducing a real-world problem to a recall-only quiz.
