Subclaims¶

Reading the evidence codes

q is the design tier, i the impact, n the sample, and the kind with its r the rigour judged within that kind: what each code means.

This claim: no standardized effect is recorded in observations/ for it yet, so no benchmark reading is possible.

q3 i? Students who left biomedical fields had significantly lower end-of-semester interest, prior achievement, and biology course grades than students who remained. → Rosenzweig 2021

q3 · i? · associational · r2

Orthogonal contrast-code regression comparing stayers to all leavers, with a Bonferroni-adjusted alpha of .0125 for the four psychological-variable tests. The article reports unstandardized b coefficients and z statistics for each difference.

"students who left biomedical fields reported significantly lower interest in biology at the end of the semester, b = −0.14, z = −6.10, p < .001, had lower prior achievement, b = −0.11, z = −5.40, p < .001, and received lower biology course grades, b = −0.13, z = −8.98, p < .001, compared to students who remained in biomedical fields."

Discussion¶

Learner Variables¶

Interest — predictor: learners who differ on it differ in outcomes
Motivation — predictor: learners who differ on it differ in outcomes

End-of-course interest in biology and introductory biology grades each predicted lower likelihood of leaving biomedical fields — possibly the same claim (merge candidate)
Interest and value were the dominant topics in leavers' explanations, especially among students leaving due to attraction — related
URM students left biomedical fields at higher rates than majority students, an effect explained in part by their lower biology course grades — related
