Thinking Habit 09

Narrow or Broaden
Thinking

Shift between specific details and the larger context to see patterns and relationships.

Driving question

Would a closer look or a wider view help me understand this?

Teacher prompts

  • Which specific detail needs a closer look?
  • What becomes visible when you examine the larger context?
  • Does this one example represent the broader pattern?
  • How does the wider view change your interpretation of the detail?

What students do

  • Notice when the current scope leaves something important unclear.
  • Narrow attention to inspect a specific detail, case, or mechanism.
  • Broaden attention to consider context, patterns, or connected parts.
  • Connect the two views to refine an explanation or decision.

See the habit in the work

A student interprets a long lunch line. Moving between one observation and a week of records changes the explanation and the proposed next step.

Illustrative classroom example · School inquiry · Understanding a lunch line

Draft

We need another lunch station because Monday’s line took twelve minutes.

The information available

In this fictional example, the line took twelve minutes on Monday and five to six minutes on each other day that week. Monday’s log records a payment-terminal restart while meals continued to be prepared.

One wait time reveals a problem on that day, but it does not show whether the same problem occurs routinely.

Draft

We need another lunch station because Monday’s line took twelve minutes.

Teacher feedback

What do the other days show? Now look closely at Monday: where did the delay occur? How should those two views affect the recommendation?

The teacher asks the student to broaden from one day to the week, then narrow to a specific event within the unusual day.

Draft

We need another lunch station because Monday’s line took twelve minutes.

Revised

Looking across the week, Monday’s twelve-minute wait was unusual. Looking more closely at Monday, the log shows a payment-terminal restart. We should investigate that interruption and collect more observations before concluding that another station is needed.

What changed: The student broadened the time frame, narrowed attention to a particular event, and used both views to qualify the recommendation.

Try it in class

Zoom in, zoom out, reconnect

  1. Choose an observation, passage, or problem. Ask students to describe it at their current level of detail.
  2. Have them inspect one specific detail, then step back to examine the larger context or a broader set of cases.
  3. Ask them to explain how the two views relate and what changes in their interpretation.

Make the shift visible

Have students record the detail they examined, the wider context they considered, and the connection that changed or strengthened their thinking.

Look for a purposeful change in scope. Naming more details or adding background is useful when it helps explain the original question or reveals a relationship that was previously missed.
