q2 i? Evaluation of the 11 pairs' pre/post circuit diagrams, drawn with no facilitator input at post-test, showed three pairs improving from incorrect to correct, seven pairs correct at both tests, and one pair designing a flawed post-test circuit. → Ioannou 2025

q2 · i? · causal · r1

Qualitative evaluation of group circuit diagrams from 11 pairs, with post-test diagrams drawn without facilitator input; three of the seven consistently-correct pairs had benefited from facilitators' scaffolding before the test. Findings triangulated the individual exercise results.

"three pairs improved their circuit design, from an incorrect drawing at pre-test to a correct one at post; one pair designed a flawed circuit in the post-test (conductive thread crossing, therefore making the circuit non-functional); and seven pairs drew a correct circuit both before and after."
