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.

q2 i0 Motivation was not a significant predictor of incidental vocabulary acquisition (β = .02, p > .05). → Zhao 2016

Evidence¶

Zhao 2016¶

Zhao, A., Guo, Y., Biales, C., & Olszewski, A. (2016). Exploring learner factors in second language (L2) incidental vocabulary acquisition through reading. Reading in a Foreign Language, 28(2). http://nflrc.hawaii.edu/rfl doi:10.64152/10125/66903

q2 · i0 · associational · r1

In the multiple linear regression (N = 129), motivation measured by the MIVLS (self-efficacy, intrinsic and extrinsic subscales, α = 0.78) was not significant: "β = .02, t = 0.17, p > .05".

"Motivation (β = .02, t = 0.17, p > .05) was not a significant predictor of L2 incidental vocabulary acquisition."

Discussion¶

Learner Variables¶

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

Incidental vocabulary learning anxiety positively predicts L2 incidental vocabulary acquisition through reading — related
L2 proficiency, anxiety, and mastery of strategies jointly explain 18% of variance in incidental vocabulary acquisition — a broader claim this one bears on
Higher L2 reading proficiency, motivation, and involvement load are associated with larger incidental vocabulary gains — reports the opposite
L2 proficiency positively predicts L2 incidental vocabulary acquisition through reading — related
Mastery of incidental vocabulary learning strategies positively predicts L2 incidental vocabulary acquisition through reading — related
