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 i? Mathematics self-concept showed a small overall decline over the school year, with significant individual variability in initial levels and change. → Lehikoinen 2025 q2 i? Individual interest showed an overall statistically significant decrease over the school year, with significant individual variability. → Lehikoinen 2025 (2)

Lehikoinen, H., Väisänen, P., Havu-Nuutinen, S., Lappalainen, K., & Niemivirta, M. (2025).

q2 · i? · causal · r1

Latent growth curve modelling of three-wave questionnaire data from 146 sixth-graders showed a negative self-concept slope. The article reports "a small overall decline in mathematics self-concept over time", with significant slope variance (S² = 0.141, p = .020).

"The results from this model showed a negative slope in students' self-concept (M =−0.081, p = .077), thus indicating a small overall decline in mathematics self-concept over time"

q2 · i? · causal · r1

Univariate latent growth model for interest in the same three-wave sample showed an overall decrease in individual interest (M = −0.154, p < .001) with significant onset and change variance. No effect size was printed.

"the results showed an overall decrease in individual interest ( M =−0.154, p < .001) as well as significant individual differences in the variance of both the onset ( S2 = 0.938, p < .001) and change over time (S2 = 0.135, p = .017)"
