Subclaims¶

q2 i? English learners who received the MLS-WEPs intervention scored 0.481 standard deviations higher on calculation and 0.702 standard deviations higher on explanation in Unit 1 than controls, holding prior knowledge constant. → Xiaojuan Ke · Kristie J. Newton 2024

Evidence¶

Xiaojuan Ke · Kristie J. Newton. (2024). English learners learn from worked example comparison in algebra. Instructional Science (2024) 52:831–858. https://doi.org/10.1007/s11251-024-09668-6

q2 · i? · causal · r2

Multiple regression on Unit 1 pre/post scores from 78 English learners in sheltered algebra classes, controlling for prior knowledge and proficiency. The intervention condition predicted higher standardized scores: "0.481 (t(77) = 2.82, p = 0.01) standard deviations higher on the calculation component" and 0.702 on explanation.

"In addition, ELs who received the intervention scored 0.481 (t(77) = 2.82, p = 0.01) standard deviations higher on the calculation component and 0.702 (t(77) = 4.77, p < 0.001) standard deviations higher on the explanation"

Discussion¶

Learner Variables¶

• Algebraic Thinking — outcome: instruction changes it
• Operations and Place Value — outcome: instruction changes it
