q2 i? Students who only received BWEs showed BW action counts and performance similar to the control group and no consistent improvement. → Preya Shabrina 2024

q2 · i? · causal · r?

Performance and BW-action analysis of the 168 completers showed the BWE-only group “behaved and performed mostly like the control group C”; T1 received insignificant higher average scores than C in problems 3.4–5.4 and showed no consistent signs of improvement.

"On the other hand, T1 students who only received BWE, behaved and performed mostly like the control group C, who were not introduced to the backward strategy at all."

Related Claims¶

• Students trained with both backward worked examples and backward problem solving significantly outperformed control and BWE-only students on posttest problem scores — related
• The BWE+BPS group constructed significantly shorter solutions than the other groups in only two posttest problems — related
• Training-level test problem scores were only marginally associated with training treatment (p=0.0563), with the BWE+BPS group scoring lower early in training — related
• Students trained with both BWE and BPS derived subgoals during proof construction with significantly higher efficiency than the other groups — related
