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? Thematic analysis of student portfolios showed rapid "error-type decay": intervention students corrected procedural misconceptions (e.g., misapplication of the chain rule) weeks ahead of control peers. → Matey Yordanov 2026

Matey Yordanov, Mikhail Bychkov, and Andrei Kuchma. (2026). The Effect of High-Frequency, Automatically-marked Formative Assessments on Student Outcomes in A-Level Sciences. https://arxiv.org/abs/2607.23566 doi:10.48550/arxiv.2607.23566
q2 · i? · causal · r2
Qualitative thematic analysis of student portfolios tracking conceptual error decay over the term. The article describes "a rapid phenomenon of ''error-type decay''" attributed to step-by-step marking; no effect size is reported.
"Because the Cortex algorithm assesses logic step-by-step (e.g., appending a ! at the precise locus of failure), students in the intervention cohort rectified fundamental procedural misconceptions (e.g., the misapplication of the chain rule in calculus) weeks in advance of their control group peers."
Discussion¶
Learner Variables¶
- Operations and Place Value — outcome: instruction changes it
Related Claims¶
- Instruction that confronts science misconceptions (conceptual-conflict interventions, refutation text) produces conceptual change more often than standard exposition — the general claim this finding bears on, with the studies behind it
- A procedural \"answer is coming\" interpretation of the equals sign leads students to chain arithmetic and errors on missing-number equations — related
- Guided ASR practice did not produce statistically significant improvement in any specific pronunciation error type, with some errors unimproved or regressed — related
- In a 16-week quasi-experiment, A-Level STEM students receiving high-frequency automated marking scored 16.8 percentage points higher on a blind-graded final mock exam than control students with human marking — related
- Dialogue evidence shows coach feedback induces genuine conceptual change, shifting the agent from misconception to conceptually correct explanation rather than superficial answer alignment — related
- On the misconception-annotated math dataset, LLMs predominantly follow a solve-first, error-injection process aligned with misconception-based distractor design — related
