Data and Analysis Materials for an Integrated Structured Generative AI Workflow for Novice Design Users

This dataset supports an exploratory within-subject evaluation of an integrated structured generative-AI workflow for novice users completing exhibition-oriented spatial-design tasks. It includes de-identified post-task questionnaire data, platform logs, screen-recording behavior coding, independent image-quality ratings, matched image-pair analysis data, response-level source-identification judgments, a prompt-level 2×2 supplementary study, pre-experiment materials, requirement-field coding materials, final design-statement coverage coding data, and manuscript-aligned statistical outputs. Direct identifiers and persistent links were removed. Raw recordings and source-identification stimulus images are not included because of privacy and reuse-rights considerations.
