IB Psychology SL Internal Assessment Example

The student states a clear, focused aim and explains why the investigation matters beyond the immediate study.

The student describes the dual-process model accurately and connects it directly to the predicted effect of font readability.

The student operationalizes the independent and dependent variables clearly, so the hypothesis is measurable and specific.

The hypothesis could be phrased more precisely in a comparative form.

A few lines imply stronger causal certainty than the evidence can support.

The link between the theory and the exact expected outcome could be stated even more sharply.

The student identifies an appropriate independent-samples design and explains why it avoids order effects.

The student describes sampling procedures and participant characteristics with enough detail to show how the study was organized.

The student includes relevant controls and materials, and several of them are linked to the purpose of keeping the procedure consistent.

The explanation of how participants were allocated to conditions is not fully clear.

The sampling choice is described more as convenient than as well justified for the research question.

Some material choices, especially the font selection and test length, would benefit from a stronger rationale.
