Cause and Consequence

By The Critical Thinking Consortium

Direct historical-thinking explanation of causes and consequences; use it to distinguish event sequence from a causal explanation.

For “Distinguish Sequence from Historical Cause,” what idea from the video helps with the lesson task, and what must still be checked in the supplied text, data or model?

Learning objective

Build a timeline and evaluate whether two proposed causes are supported by the supplied sources.

Before you begin

  • Order events on a timeline; distinguish a source from an inference.

Gather your materials

  • Paper or a note-taking document
  • Pencil; the original lesson texts and records below

Language to know

Chronology
An arrangement of events by time.
Causation
A relationship in which one condition or event helps produce another.
Corroboration
Checking a claim against independent relevant evidence.

Understand the concept

Fictional historical model, not an actual port: a council ledger dates a road repair to Year 4; toll receipts rise in Year 5; a merchant’s Year 6 letter says “I came because the inland fair moved here”; an undated later summary credits the road alone. A sequence shows that repair preceded higher receipts, but not why receipts rose. The letter offers another mechanism, while one merchant’s account cannot explain every arrival. Historical causation requires a proposed link, relevant evidence and attention to alternatives, not merely an earlier date.

Teach it step by step

  1. Place the dated records on a timeline and keep the undated summary separate.
  2. Distinguish the ledger’s observation from the summary’s explanation.
  3. Compare road repair and fair relocation as possible causes, stating evidence and limits for each.
  4. Write a qualified causal paragraph and name one source that could test the competing explanations.

Make the thinking visible

Worked example or model response

“Road repair preceded the receipt increase, but the merchant identifies a relocated fair as a reason for one visit. The evidence supports investigating both conditions rather than attributing the entire increase to the road. More letters or records of fair dates would help test their relative roles.”

Guided practice

Together evaluate “Year 4 must have caused Year 5 because it came first.” Identify the missing reasoning.

Independent practice

Write a four-event source timeline and a 120-word evaluation comparing two causes. Explain why the later summary’s date and source base matter.

Quick assessment

Can two causes both contribute without the dossier establishing how much each mattered?

Answer key & assessment criteria

Answers and teaching guidance

  1. Guided: Temporal order is necessary for this proposed cause but does not supply a mechanism or rule out alternatives.
  2. Independent criteria: Timeline preserves dates and uncertainty; paragraph distinguishes observations from explanations, assesses both causes and requests relevant corroboration.
  3. Quick check: Yes. Multiple contributing conditions are possible; the limited sources do not quantify their relative effects.

Look for: Timeline preserves dates and uncertainty; paragraph distinguishes observations from explanations, assesses both causes and requests relevant corroboration. Accept a different conclusion when it addresses the task and is supported by the supplied material.

Make it work for your learner

More support

Provide dated source cards and a cause/evidence/alternative chart.

Extension challenge

Add a fictional toll-rate change and explain why receipts alone would then be an even weaker measure of trade volume.
