Instrumented One-Dimensional Cutting-Stock Educational Exercise: Replication Package

This record provides the replication package for an instrumented browser-based educational exercise on the one-dimensional cutting-stock problem. The package includes the current Brazilian Portuguese and English versions of the student instrument, byte-preserved historical versions used during the original study, a deterministic Python and JavaScript verifier, an English class dashboard, session-log schema and examples, 22 consented session logs without direct personal identifiers, independent human coding, automated tests, reproducibility scripts, and the generated results used to verify the quantitative claims reported in the associated study. The instructional task uses a fixed cutting-stock instance with 48 pieces and bar capacity 8.5. First Fit Decreasing (FFD) uses 14 bars for this instance, while the exact verifier proves an optimum of 13 bars. The replication workflow distinguishes result fidelity (matches_ffd_result) from procedural fidelity (followed_ffd_procedure and ffd_process_errors). The package is fully reproducible from the included scripts. At release, all 48 automated tests passed, including JavaScript/Python equivalence checks. The reproduced outputs match the bundled expected_results.json, and the pre-deposit privacy audit reports 22 session files, 22 unique technical session identifiers, 22 human-coding rows, and no direct-identifier issues. The deposited archive was deterministically generated from Git commit: 09c841040495608313ea19cb1100a21fdd9c626b Archive SHA-256: e8de0ad1bc28b93c42f713d697599d4d01eb5255ae9be6ec4ee9dc5a795f5174 Software components are licensed under the MIT License.
