IB Grade: A

Criteria A: Focus and Method

6/6

Criteria StrandsPro

A.1Topic communication and clarity

Excellent

A.2Research question formulation and focus

Excellent

A.3Research methodology

Moderate

Criteria Feedback

The student defines a focused investigation and keeps the central question visible throughout most of the report.
The student narrows the scope to two key sprint variables, which makes the study manageable and purposeful.
The student's method shows clear modelling intent through segmented calculations and graph-based comparison.

The student's research question wording is a little awkward and could be more precise and academic.
The method would be stronger if the data selection and Excel process were explained more transparently.
Some of the source choices and the way the athletes were paired are not fully justified.

Criteria B: Knowledge and Understanding

4/6

Criteria StrandsPro

B.1Subject knowledge application

Good

B.2Use of terminology and concepts

Moderate

Criteria Feedback

The student shows solid understanding of sprint biomechanics and applies relevant ideas such as force, inertia, and neuromuscular control.
The student uses scientific terminology effectively in many places, which helps their explanation sound appropriately technical.
The student makes a good attempt to connect physiological ideas directly to the performance variables they are studying.

Some terminology is used inconsistently, especially around stride and step frequency.
A few physiological explanations are oversimplified, especially where sprint fatigue and ATP use are discussed.
Some claims are broader than the evidence in the student's report really supports.
