Claim-Evidence-Reasoning (CER) data stories prompt students to interpret a graph in terms of a written claim, and then explain how specific features of the graph led them to make their claim, or how it supports a provided claim.
Goal: Prompt students to state a claim, and explain how features of a graph support the claim.
Example 1: Tuva Data Story Adaptation to Environmental Change
Two box plots show the distribution of measurements of beak depth (how big the beak is) for finches before and after a year of drought in the Galapagos Islands. Students are given the following prompts:
Implementation ideas: Assign Claim, Evidence, Reasoning data stories as straightforward practice for making (or evaluating) claims, linking them to specific features of a graph, and connecting the claim to wider meaning or implications.

Example 2: Tuva Data Story Where do Earthquakes and Volcanoes Occur?
