Experimental Data (EXPERIMENTAL_DATA)</p><p dir="ltr">Individual participant metrics recorded during the experiment:</p><ul><li>Group and Expertise Level: Assigned group (Control vs. Experimental) and skill level (determined by the researchers through a preliminary skills survey).</li><li>Performance: Task resolution times (hh:mm:ss) and perceived difficulty (Likert scale) for each of the 5 tasks (T1 to T5).</li><li>Process Variables: Indicators of whether the participant encountered major problems, used AI assistants (Copilot, ChatGPT), or relied on traditional resources (Google, StackOverflow).</li></ul><p dir="ltr">2.

Session Metrics (EXPERIMENTAL_BUNDLES_SUMMARY)</p><p dir="ltr">Quantitative measurements extracted directly from the IDE session logs:</p><ul><li>Total and valid session files generated.</li><li>Total context switches (total vs. those involving code changes).</li><li>Average number of distinct files explored before making modifications.</li></ul><p dir="ltr">3. Usability Evaluation (SUS)</p><p dir="ltr">Responses from the experimental group to the System Usability Scale (SUS) questionnaire:</p><ul><li>Scores per question (Q1 to Q10), sum of scores, and adjusted final score (on a 0-100 scale).</li></ul><p dir="ltr">4.
