Why is PBL so hard to implement at scale?
Three reasons. First, there's a training problem: most PBL professional development uses sit-and-get delivery to teach an experiential approach. Teachers who haven't experienced PBL as learners aren't ready to design it for students. You can't learn to swim from a lecture.
Second, there's a belief problem. The most difficult barrier isn't logistics or curriculum — it's whether teachers genuinely believe their students are capable of sustained, self-directed inquiry. If the answer is no, every PBL unit will be over-scaffolded into something that looks like a project but functions like a worksheet.
Third, there's a leadership problem. PBL implementation requires active instructional leadership support — not just approval from a distance. Leaders need to understand PBL well enough to visit classrooms, have informed conversations about what they see, and make resource decisions that support the work.

What's the difference between doing projects and doing project-based learning?
In traditional projects, students learn content first and then apply it to a project at the end of a unit — the project is a culminating activity.
How can school leaders support PBL implementation?
By going beyond cheerleading.
How does PBL connect to real-world audiences and experiences?
Through a design element that most traditional instruction lacks entirely: authentic audience.
