Criteria Breakdown
Criterion A: Focus and Method —
6/6
The research question “Can one find the most optimal caffeine dosage schedule with the use of mathematical modeling?” is clearly stated and highly focused. The methodology is complete and systematic, demonstrated through the five-step model construction process (concentration → effect → tolerance → productivity → optimization). Evidence of informed selection is strong: the student justifies choosing d_w = 4 hours to prevent unrealistic micro-dosing and d_m = 5 minutes to balance accuracy with computational efficiency. The approach is appropriate for Computer Science, effectively integrating machine learning techniques with pharmacokinetic modeling. The topic is communicated accurately throughout with precise technical descriptions.
Criterion B: Knowledge and Understanding —
6/6
Criterion C: Critical Thinking-
6/6
Criterion D: Presentation —
4/4
Criterion E: Engagement —
0/6
The Reflections on Planning and Progress Form (RPPF) is missing from the submission. According to IB requirements and the explicit instructions provided, without the RPPF it is impossible to assess the student's engagement with the research process, including their planning, decision-making, and personal reflection on challenges.
