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 i2 Using place value labels was positively correlated with decimal number line (r=.32) and equivalency (r=.45) accuracy, while whole number labels were negatively correlated (r=-.32, r=-.34). → Malone Amelia S. 2017

Evidence¶

Malone Amelia S. 2017¶

Malone Amelia S., Loehr Abbey M., Fuchs Lynn S. (2017). The Role of Domain-General Cognitive Abilities and Decimal Labels in At-Risk Fourth-Grade Students' Decimal Magnitude Understanding. Learning and Individual Differences. https://doi.org/10.1016/j.lindif.2017.05.007

q3 · i2 · associational · r2

Correlational analysis (Table 5) among 127 at-risk fourth graders: place value labels r=.32** with Number Line and r=.45** with Decimal Equivalency; whole number labels r=-.32** and r=-.34** respectively.

"Using place value labels was positively correlated with students' decimal magnitude understanding, whereas using whole-number labels was negatively correlated with students' decimal magnitude understanding."

Discussion¶

Learner Variables¶

Operations and Place Value — predictor: learners who differ on it differ in outcomes

Cognitive abilities correlate with decimal label use patterns — related
Place value label use correlates with accuracy on fraction-decimal equivalency items — a narrower finding that bears on this claim
Domain-general cognitive abilities predict at-risk fourth graders' decimal magnitude understanding — related
Most at-risk fourth graders apply whole-number logic when comparing decimals with different digit counts — related
