A version-aware evidence pipeline for input during educational-technology development

Definitions and mathematical statement

Shared notation.
Standard number systems are $\mathbb N,\mathbb Z,\mathbb Q,\mathbb R,\mathbb C$. Specialized notation and index ranges follow the cited source and the definitions below.

A development study gathers evidence relevant to a software or instructional design choice. Its population, tool version, intervention, and outcome define what the results can support. Feedback from users is one type of evidence and is not automatically a controlled effectiveness comparison.

Record scope and qualifications.
The catalogue title is retained as metadata. Named certificates, contracts, bounds or frameworks in that title are not asserted as results of the original source extract. No proposed feature, study design, outcome, or decision criterion is fixed. The supplied catalogue marks this record open; its present research status was not independently checked. The source text below is rendered literally where necessary; damaged formulas and composite extracts are not silently repaired into a new mathematical claim.
Statement recorded in the supplied source.
5. How to give input as the technology is developed?

- What studies will help to answer that question? [S2]

Source status.
The supplied catalogue labels this source record open; that metadata was checked against the supplied snapshot on 2026-10-11. The label is preserved for provenance and is not an independent verification of present open status or mathematical correctness.

Short English statement

The source asks how research can inform assessment-technology development.

Sources

Preparation and review.
The original source and UnsolvedMath contributors retain attribution for the source extract. Codex (GPT-6; exact serving revision not exposed) assisted with definitions, English summaries, scope notes and formatting. No new human mathematical authorship or independently verified solution is asserted. Permanent source ID 20002105 and code AIM-INFRASTRUCTURE-0005 checked against the complete supplied registry and current repository. Distinct upstream records, including repeated questions and broad or damaged extracts, are retained for complete coverage of the source CS category. A repeated record is not a new independent conjecture. Complete mathematical-equivalence and current-literature review has not been performed. Preparation and final review follow contribution prompts C and D, with source gaps disclosed. Structural and rendering checks do not establish a new theorem or open status.

Research attempt

Literature, source context and scope

The primary AIM notes describe a brainstorming session. The original excerpt and all catalogue qualifications remain above. They do not specify a mathematical theorem or a complete empirical study. The formal model below is an explicitly limited research route introduced for this attempt, not a reconstruction of a missing original conjecture. The supplied catalogue's earlier research summary was inspected as context; its named framework is not adopted as an established solution. The elementary result below is not claimed novel, and no educational effectiveness data were collected.

Attempt: using development feedback to select and evaluate features

I tested the common inference that the best observed pilot result estimates the quality of the feature selected during development. The model has $m$ candidate versions of equal true success probability $1/2$, each receiving one independent Bernoulli pilot observation $X_j$. It isolates selection bias; it is not a complete study design.
Proposition: The selected pilot maximum has expectation $1-2^{-m}$ although every candidate has true success probability $1/2$. An independent fresh outcome for the selected candidate has expectation $1/2$.
Proof: The maximum is zero exactly when all $m$ independent observations are zero, an event of probability $2^{-m}$. Since it is binary, its expectation is $1-2^{-m}$. Choose an index $J$ attaining the maximum by any fixed tie rule based only on pilot data. Conditional on the complete pilot data, $J$ is fixed and a fresh outcome $Y_J$, independent of those data, has mean $1/2$. Taking expectations gives $E(Y_J)=1/2$. More generally, if candidate means are $p_j$, the fresh selected outcome is conditionally unbiased for $p_J$; the pilot maximum need not be. ∎

Verification and remaining gaps

For eight candidates the expected displayed winning pilot is $255/256$, while the fresh success probability is $1/2$. Enumerating all 256 equally likely pilot vectors checks the first value. The false inference is reusing selection evidence as an unbiased evaluation of the selected version. Fresh evaluation removes this particular dependence under the stated assumptions, but it does not establish a learning construct, appropriate comparison, version stability, representativeness or which user inputs are useful. The broad development-research agenda remains unresolved.

References and source attribution

American Institute of Mathematics, workshop discussion notes on open educational resources and assessment, https://aimath.org/pastworkshops/oerassessmentproblems.pdf. The 16-page primary PDF was opened on 11 October 2026 and its numbered brainstorming item was checked against the supplied record. The source supports the provenance and agenda, not the additional modeling assumptions or an empirical educational conclusion. Catalogue and contributor attribution are retained in the reproduced Sources section. The worked mathematics is proved here without reliance on an unverified external theorem.
Integration review.
Codex (GPT-6; exact serving revision not exposed) reviewed the written arguments and expanded layout and source-reference wrappers. Repository metadata and the production web renderer were checked using Python 3.13 and JavaScript with MathJax 3.2.2. This model-assisted review is not independent human proof verification; no PDF compilation or formal proof checking is asserted.

Completion Estimate

COMPLETION: 0% No substantiated new progress toward the entire original target is claimed. The worked results and failed route are delimited above; a known result, illustrative model, or auxiliary obstruction is not counted as original-target completion.

Final status and attribution

Attempt status: unresolved. This describes this research attempt, not a new ruling on the source catalogue's status or on external literature claims. The mathematics and this self-audit were generated by OpenAI gpt-6-astra, reasoning ultra, on 11 October 2026. Codex (GPT-6; exact serving revision not exposed) orchestrated the batch and contributed formatting/repository review. No human mathematical authorship, independent human proof checking, or formal verification is claimed. The historical preparation paragraphs in the reproduced catalogue body concern that body only.

Contribution prompt A was applied to the complete definition and supplied source record, followed by the adversarial checks of prompt B. Local reproduction files are batch008/checks.py, computations.json, and the per-ID audit JSON. They were not public links at preparation time. Numerical checks are finite and do not prove unrestricted results. No LaTeX engine was found locally; compilation was not performed by this research agent.
