  1. For better readability, we did not report max/min scores as they ranged mostly from 0 to 1
  2. T0 pretest, T1 posttest, T2 delayed posttest, SF faces questions under “simple,” SE edges questions under “simple,” SV vertices questions under “simple,” AF faces questions under “advances,” AE edges questions under “advances,” AV vertices questions under “advances”
