Inquiry-Based Learning

Incoming material is kept when a written question is already waiting for it, ahead of opening the source. Purpose is what decides what is kept, and questions are how purpose gets manufactured. Writing a problem and then satisfying it changes both what gets consumed and how that material is thought about. Without a written question, part of the effort during intake goes to deciding what is even relevant, and that sort runs at the same time as the material arrives. Intake without a question is like running down a road because someone said to, then realising an hour in that the destination was never named.

Red light

The house name for the routine is Traffic Light: red light writes the questions, green light answers them. Unfocused intake takes in too much at once, is harder to process, is forgotten quickly, costs the time of relearning, and feels tedious. Red light is what breaks the habit of reading to consume.

Red starts with a list of keywords and concepts — enough to cover the topic’s main ideas, not every term on the page. Those keywords get four stems: which feel most relevant or easiest, and those are where it starts; what there is curiosity about; why this needs knowing; what problem it solves or how it would be applied. Working the stems raises further questions, especially off curiosity, and those get written down too. Red light ends with a written list of questions.

Keywords in: rainfall, drains, soil, paving.
Questions out: why does paving change where the water goes ·
what does saturated soil stop doing · where does a drain fail first ·
how would this street flood differently after a week of rain.

Green light

Green reads, listens, and searches to satisfy those questions rather than to memorise everything. Each question is there to open several relationships rather than to collect a single correct reply, so green hunts for more than one answer. Relationships get expressed in the notes, messy at first. Every two or three keywords, the map gets simplified and judged for what is worth keeping.

The relationships found exceed what can be held mentally, which is why they go on paper and go non-linear — the note form Non Linear Note Making exists to hold. What is drawn during green light exists to hold thinking outside the head and to make the flow visible, not to record a result, so the structure stays provisional until much later. Detail too fine-grained to answer any question goes to rote memorisation for now: parked until it becomes relevant, not written off.

The loop

Green ends when red’s questions are answered. Then red comes again. Each pass surfaces material that raises the next pass’s questions, so the cycle compounds until most of the topic has been covered. Early questions are not going to be good ones. Struggling with them is normal, and the asking continues anyway.

The objective is becoming familiar with how asking questions changes the processing of new material, not finishing the topic.

The price is a pass of question-writing before any reading starts, and notes that stay messy through the middle.

The name collision

The mainstream classroom version is genuinely contested. There is no agreed definition of what inquiry even is, no clear guidance on how it is to be implemented, heavy dependence on the facilitator, and effectiveness that varies widely across studies. Most of that research is aimed at educators and curriculum makers rather than at a person studying alone. Comparison research finds unassisted discovery losing to explicit instruction, while discovery with feedback, worked examples, and scaffolding can beat it. A self-written question list with a stopping rule is the scaffolded kind, not the unassisted kind. Implemented badly, the classroom version is useless or harmful.

This version is framed from a cognitivist, self-regulated angle under cognitive load theory, keeping the part that survives that framing: the written question removes the concurrent relevance sort. Treated as the textbook version, the criticisms stand.

This routine is substantially modified, and it is not what mainstream research calls inquiry-based learning.

What it should produce

The starting keyword does not decide the outcome, because working the questions surfaces which keywords are the important ones. Groups come from comparing concepts against each other, not from the order the source presented them in and not from what was assumed before starting. A map that keeps reproducing the source’s own arrangement means the questions are not doing the work yet.

Order Control is the order the questions pull, against the order the source is arranged in. Survive and Thrive is why relationship-building is what gets knowledge kept. Higher Order Learning is comparing, judging, and connecting — what the questions are for.

After several loops the map is a structure built from the learner’s own judgments about what matters, which is what the opening claim looks like once it has run. The same loop tightens later inside the Bear Hunter System: aim takes over from red light, and shoot from green.
