IB Psychology SL Internal Assessment Example

The student states a clear aim that matches the rest of the investigation and explains why the topic matters beyond the experiment itself.

The student describes the theoretical framework accurately enough for the reader to understand the logic behind the study.

The student operationalizes both variables clearly, making it easy to see how the hypothesis can be tested.

The hypotheses use broader wording rather than fully embedding the operational definitions directly.

The theoretical explanation could be made even more precise by stating the exact mechanism the student expects to drive memory improvement.

The student describes the research design clearly and explains why the independent-groups approach is useful.

The student gives a relevant participant description and explains why this sample is appropriate for the investigation.

The student describes the materials and controls in a way that shows awareness of how to reduce confounding variables.

Some controls could be explained more explicitly, especially how fairness was maintained across conditions.

The sampling rationale would be even stronger if the student named more clearly which participant characteristics mattered most and why.
