It is always a interesting to compare and contrast the differing views of students on key questions.

When the debate can be reduced to an either/or option (e.g. ‘success or failure?’, ‘hero or villain?’) this can be done most simply by students organising themselves along a continuum line.

When the debate is based around three main interpretations, I arrange the three options on different points of a triangle. Students have to then write their initials in the appropriate spot to indicate their respective ‘leaning’:

Why did Franco win the Spanish Civil War?

In the example above (“Why did Franco win the Spanish Civil War?”), students wrote their initials in two separate triangles. The first reflects the relative importance of Nationalist Strengths, Republican Weaknesses and International Factors; the second covers Military, Socio-Economic and Political Factors.

The method is a simple one but provides a visual snapshot of what students are thinking and which students in particular are most in disagreement.

Taking it further

  • Get students who are most clearly in disagreement to explain their choices to the class. Allow other members of the class to adjust their position in the triangle based on what they hear.
  • Blank out the central part of the triangle. This prevents students from defaulting at the ‘safe’ option of placing themselves in the middle of the triangle to avoid ‘leaning’ towards any particular interpretation:
"Account for the Union victory in the American Civil War" Did Richard III kill the Princes in the Tower?
