q2 · i? · qualitative · r3

Qualitative analysis of opinion-based comments in the think-aloud protocols, discussed in the article's interpretation of students' reflection on their own position when reading the other-side account. Counts are descriptive; no statistical test is reported for this shift.

"the think-aloud comments against the “own-side” doubled, while statements supporting their “own-side” decreased by half in the final assessment compared to the initial assessment."

q2 · i? · causal · r1

Case-study and count-based qualitative analysis: five pupils expressed other-side-supporting opinions at posttest (only one had at pretest) and six expressed opinions against the Greek side at posttest (one at pretest), yielding "a total of 8 pupils" with evidence of a shift.

"In other words, a total of 8 pupils show evidence that they have shifted from one- sided to two-sided reasoning after the intervention."
