How to run The Shared River as Problem-Based Learning: your role, the pre-planning maps, pacing, role cards, sources, and debrief prompts. The golden rule — guide, don't tell. In PBL the students should feel they, not you, planned the investigation.
| Phase | What you do | What you resist |
|---|---|---|
| ① Surface | Teach vocabulary and facts efficiently; run the jigsaw; check acquisition of the map & data. | Rushing to the problem before facts are secure. |
| ② Deep | Facilitate the resource–needs concept map and source routine; model claim + evidence. | Giving your own interpretation of the sources or data. |
| ③ Transfer | Read the problem well; hold the KWHL chart; answer questions with questions; point to sources. | Answering the “Need to know” questions yourself, or handing students the “right” agreement. |
The Surface phase uses a four-topic jigsaw (What makes a region?) — a high-leverage move (d ≈ 0.92) because every student must teach. The flow: expert groups each study one topic and take notes → students re-mix into home groups with one expert per topic → each expert teaches → an individual check for understanding holds everyone accountable.
The per-expert-group source links (articles + reference pages) live on the Surface page, one set per topic. Confirm access through your district before class.
Before teaching, brainstorm every direction the shared-river problem could branch — so you can steer discussion and decide, in advance, which threads are productive and which are too sensitive or off-topic for your class and community.
