Use the Zoom In strategy

Use the Zoom In strategy to have students look closer at part of a graph or table and revise their interpretation.

How-to guide Teaching with Tuva

Last reviewed: February 2021

Zoom-In data stories prompt students to look at a portion of a graph or table in greater detail by “zooming in” or “zooming out,” or to consider how the addition of new information affects an interpretation. 

Goal:  Students look more closely at data to explain patterns or modify an interpretation or prediction when presented with new information or a view of data at a different scale.

Example: Tuva Data Story Where Does Electricity Come From? 

Students compare electricity generation by wind and solar during recent decades. Then explain how and why patterns change when other sources of energy are added.

Part 1:

 

Line graph of US wind and solar electricity generation climbing over time, wind well ahead of solar

 

  • What similarities do you notice in wind and solar electricity generation in the US?
  • How are patterns in wind and solar electricity generation different?
  • What questions does the graph of wind and solar raise for you?

Part 2:

 

Line graph of US electricity generation by source, showing coal declining as natural gas rises

 

  • What new patterns do you notice in the graph?
  • An explanation for how patterns in the graph changed could be _____.
  • After thinking about this graph, I am wondering _____.

Implementation ideas: 

Use Zoom-In data stories to introduce the NGSS cross-cutting concept of Scale, Proportion, and Quantity. Students can create a headline for graphs at different scales, and compare the key idea communicated by each graph.
