IB Psychology HL Internal Assessment Example

The student states a clear, testable aim and explains why the investigation matters in an educational context.

The student connects Dual System Theory directly to the task rather than leaving it as background information.

The student operationalizes both variables clearly in the hypothesis, which makes the study easy to understand and investigate.

The student's causal language is sometimes too strong, so the theory link would be more precise if phrased more cautiously.

The null hypothesis could be matched more closely to the research hypothesis in terms of wording and operational detail.

A brief acknowledgement of alternative explanations would make the introduction even more rigorous.

The student explains why an independent-groups design fits the investigation and how it helps reduce order effects.

The student describes the participant characteristics clearly and includes relevant sampling details.

The student outlines the main controls and materials in a way that shows awareness of standardization and comparison with the original study.

Some of the student's justifications go beyond what the sampling method can actually guarantee, especially around ability and withdrawal.

The materials description would be stronger if it included exact font details and other presentation specifics.

The student's explanation of the time limit could be more fully justified rather than simply stated.
