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 i1 The main effect of task difficulty was significant (Wilks' Lambda = .86, p < .05, ŋ2 = .14) on intrinsic (ŋ2 = .07) and extraneous cognitive load (ŋ2 = .09). → Gupta 2020 q3 i? No significant difference between difficult and easy tasks was found for germane cognitive load (F = .204). → Gupta 2020 (2)

q3 · i1 · causal · r2

In a 2 x 2 x 2 factorial experiment with college students solving simultaneous equations, task difficulty was defined by solution steps; "The analysis on the main effect of task difficulty was significant (Wilks’ Lambda λ = .86, p < .05, ŋ2 = .14)" for intrinsic (F1, 107 = 8.60, ŋ2 = .07) and extraneous load (F1, 107 = 9.92, ŋ2 = .09).

"The analysis on the main effect of task difficulty was significant (Wilks’ Lambda λ = .86, p < .05, ŋ2 = .14) as measured by intrinsic (F1, 107 = 8.60, p < .01, ŋ2 = .07) and extraneous cognitive load (F1, 107 = 9.92, p < .01, ŋ2 = .09)"

q3 · i? · causal · r2

Same experiment, task-difficulty contrast on the CLM germane subscale: "no significance was found for germane cognitive load ( F = .204, p < .653)". The authors suggest load from difficulty "may render germane cognitive load unavailable for learning".

"but no significance was found for germane cognitive load ( F = .204, p < .653). The results indicate high intrinsic or extraneous cognitive load due to task difficulty may render germane cognitive load unavailable for learning."
