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 in the personalization condition spent significantly less time solving hard KC problem parts in Unit 6 (6.93 second reduction, p = 0.048). → Walkington 2013 q3 i? Students who had received personalization were still faster at writing expressions in Unit 10 (6.26 second reduction, p = 0.004). → Walkington 2013 (2)

Evidence

Walkington 2013

Walkington, C. A. (2013). Using adaptive learning technologies to personalize instruction to student interests: The impact of relevant contexts on performance and learning outcomes. Journal of Educational Psychology, 105(4), 932–945. doi:10.1037/a0031882

q3 · i? · causal · r2

Hierarchical linear regression of step duration in Unit 6. Experimental students showed a "6.93 second reduction, p = 0.048" on hard KCs. Experimental group achieved 0.59 correct per minute versus 0.42 for controls on hard KCs.

"Students in the personalization condition spent significantly less time (6.93 second reduction, p = 0.048) solving problem parts involving hard KCs in Unit 6"

q3 · i? · causal · r2

Hierarchical linear regression of step duration in Unit 10. Students previously personalized showed a "6.26 second reduction, p = 0.004" on expression-writing, suggesting accelerated future learning. No significant time differences for easy or medium KCs.

"Students who had received personalization in Unit 6 were still faster at writing algebraic expressions in Unit 10 (6.26 second reduction, p = 0.004; Table 8)."
