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? In Extract 2, algebraic errors committed while working outside the topic of geometry caused a discontinuity, yet learners ultimately evaluated a and b, resulting in effective folding back. → Mabotja 2018

q2 · i? · qualitative · r3
Qualitative analysis of Extract 2, where learners Lesiba and Lebogang misread side labels and made algebraic errors while solving for magnitudes a and b after establishing triangle similarity. The authors report the discontinuity was overcome through critical sharing of ideas.
"This led to a discontinuity that emanated from algebraic errors committed while working outside the topic of geometry."
Discussion¶
Learner Variables¶
- Algebraic Thinking — predictor: learners who differ on it differ in outcomes
