Subclaims¶

q2 i? Understanding of matching polarity improved significantly (p = .039) and mistakes in missing connections were significantly reduced (p = .031); improvements in connection type, redundant connections, and crossing lines/short circuits were not statistically significant. → Ioannou 2025

Ioannou, A., Miliou, O., Georgiou, Y., Timotheou, S., Barkhuus, L., & Rode, J. (2025). Learning design for short-duration e-textile workshops: outcomes on knowledge and skills. Education Tech Research Dev, 73, 443–463. https://doi.org/10.1007/s11423-024-10411-8

q2 · i? · design · r2

McNemar tests on individual pre/post knowledge exercises (n = 22) scoring connection, polarity, and current flow as present/absent. Table 3 reports polarity matched rising from 1 to 8 and missing connections falling from 10 to 4; only p = .039 and p = .031 reach significance.

"There was a significant improvement of students' understanding of matching polarity (p = .039) and a significant reduction in their mistakes in relation to missing connections (p = .031). Last, we found an improvement, albeit not statistically significant, of students' understanding of the remaining features of a simple circuit."
