Subclaims¶

q3 i? Bootstrapped indirect effects via biology course grade were significant for enrollment in the second course (.08, 95% CI [.0172, .1781]) and STEM major persistence (.06, 95% CI [.0007, .1685]). → Canning 2018

q3 · i? · causal · r3

Bootstrapping mediation analysis (Hayes' PROCESS, 5,000 samples) in the randomized experiment testing course grade as mediator of UV effects on retention outcomes. The article concludes "biology course grade partially mediated the positive effect of the UV intervention"; indirect effects are unstandardized, so no effect size magnitude is coded.

"Results based on 5,000 bootstrapped samples indicate that the indirect effect via biology course grade equaled .08, 95% CI [.0172, .1781] for enrollment in the second course and .06, 95% CI [.0007, .1685] for STEM major persistence. The confidence intervals of the indirect effects do not include zero; thus we can conclude that biology course grade partially mediated the positive effect of the UV intervention on continuation to the second course of the sequence and STEM major persistence."

Discussion¶

Related Claims¶

• A UV essay in the final unit of the course promotes enrollment in the second biology course, especially for high-performing students — a narrower finding that bears on this claim
• A utility-value writing intervention increases continuation to the second course of the biology sequence — a broader claim this one bears on
• A utility-value writing intervention increases STEM major persistence across the semester — related
