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? Among changed comments, Multi-Step-Block is the clearest hotspot, followed by Conditional-Return, Output-Formatting, Conditional, and Arithmetic-Update, and the widest flows end in Heavy Modification, suggesting students more often needed substantial restructuring than minor edits. → fig2-flows

Trace of changed comments from question to construct to modification category (Figure 2), covering the top seven constructs (5,692 of 6,221 events), with BankAccount dominating change events. No effect size is printed.
"Multi-Step-Blockis the clearest hotspot, followed by Conditional-Return,Output-Formatting,Conditional, andArithmetic-Update. The widest flows end inHeavy Modification, especially forMulti-Step-Block, suggesting students more often needed substantial restructuring than minor edits."
Discussion¶
Related Claims¶
- Students shift toward How comments for procedural constructs: 94.3% of Multi-Step-Block and 57.3% of Loop-Iteration comments were How comments — related
- Students rarely rewrite specification comments: within the first 10 attempts, Unchanged (48.4%) and New (41.3%) dominate while substantial revisions total only 4.4% — a broader claim this one bears on
- Low comment rewriting does not imply a smooth process: students describe the main effort as verifying generated code rather than revising prompts — related
- Student comments directing AI code generation are dominated by What comments, with How comments second and Why comments rare — related
- Creating computational literature develops computational literacy even when code modification is minor — related
