VENT-RED v1.0 — Pedagogical impact dataset: student survey responses, R analysis script, and run log

This deposit accompanies the manuscript "Computational transparency as cognitive scaffolding in resource-constrained engineering education: Technical validation and pedagogical impact of an open-access ventilation design tool" (Benavides-Muñoz, Heras-Benavides & Feijoo Veintimilla, 2026). It contains the full reproducibility package for the pedagogical impact analysis of VENT-RED v1.0, a free and open-access duct-sizing tool tested with 189 engineering students across three cohorts at Universidad Técnica Particular de Loja (Ecuador). Files Input_data.xlsx — Anonymised survey responses (N = 189; Student_ID, Group, and five 5-point Likert items: Manual_Complex, Time_Reduction, Conceptual_Understanding, Design_Confidence, Transparency_Learning). VENT-RED.R — Single-file R script that ingests Input_data.xlsx and reproduces every table (T01–T11) and figure (F2–F12) reported in the manuscript: descriptive statistics, Cronbach α, diverging Likert plots, one-sample tests against the neutral midpoint, Kruskal–Wallis with Dunn post-hoc, Spearman correlations, multiple linear regression with diagnostics, VIF, LMG relative-importance decomposition, and cohort × item agreement heatmap. 00_run_log.txt — Verbatim console capture from one full execution of the script, including all tables and the academic interpretation block. Reproducibility. Place all three files in the same working directory and run the script in R ≥ 4.2. Required CRAN packages are listed and auto-installed at the top of the script. Outputs are written to ./FIGS_VENT/ as PNG (600 dpi), SVG, PDF and XLSX. A sessionInfo.txt is generated automatically.本附属数据集存档配套稿件《资源受限工程教育中的计算透明度作为认知支架：一款开源通风设计工具的技术验证与教学影响》（Benavides-Muñoz、Heras-Benavides与Feijoo Veintimilla，2026）。本包包含VENT-RED v1.0教学影响分析的完整可复现性研究包，VENT-RED v1.0是一款免费开源的风管选型工具，已在厄瓜多尔洛哈私立技术大学的3届共189名工科学生中开展测试。 Files - Input_data.xlsx：匿名化问卷调研数据（样本量N=189；包含字段：Student_ID、Group，以及5个5点李克特（Likert）量表题项：Manual_Complex、Time_Reduction、Conceptual_Understanding、Design_Confidence、Transparency_Learning）。 - VENT-RED.R：单文件R脚本，可读取Input_data.xlsx并复现稿件中报告的全部表格（T01–T11）与图表（F2–F12），具体包括：描述性统计、克隆巴赫α系数（Cronbach α）、发散式李克特量表绘图、以中性中点为基准的单样本检验、Kruskal-Wallis检验搭配Dunn事后检验、斯皮尔曼相关性分析、带诊断分析的多元线性回归、方差膨胀因子（VIF）、LMG相对重要性分解，以及批次×题项一致性热图。 - 00_run_log.txt：脚本完整运行一次的原始控制台输出记录，包含所有表格与学术解读模块。 复现说明：将全部3个文件置于同一工作目录，在R版本≥4.2的环境中运行该脚本。脚本顶部已列出所需CRAN软件包并将自动完成安装。所有输出结果将保存至./FIGS_VENT/目录，格式包括PNG（600dpi）、SVG、PDF与XLSX。系统将自动生成sessionInfo.txt会话信息文件。
