IB Psychology HL Internal Assessment Example

The student stated a clear, focused aim and explained why it matters beyond the investigation itself.

The student described schema theory accurately and linked it convincingly to the memory task.

The student identified the independent and dependent variables correctly and showed strong awareness of how they operate in the study.

The hypothesis would be stronger if the operational details were built directly into the prediction rather than stated separately.

The rationale for the background study could be made slightly more precise in how it supports the student's exact comparison.

The student clearly described the independent-measures design and explained why it was suitable for this memory task.

The student identified the sampling method and participant characteristics clearly, with a sensible rationale for the chosen group.

The student described the controlled variables and materials in enough detail to show awareness of how to keep the task fair and consistent.

Some explanations would be stronger if the student discussed the trade-off in representativeness as well as the practical benefits of the method.

A few controls are explained mainly in terms of what could go wrong, rather than directly in terms of how they protect validity.

The preparation of the uncategorised materials could be justified more explicitly.
