IB Psychology HL Internal Assessment Example

The student states a focused aim and clearly explains why the investigation matters beyond the experiment itself.

The student's theory is described accurately and linked to the wording manipulation in a meaningful way.

The student's hypothesis is directional and operationalized, with both conditions and the speed estimate made measurable.

The dependent variable should be defined more precisely as each participant's speed estimate in km/h rather than as a mean speed estimate.

The theoretical framing would be stronger if the student distinguished schema theory more clearly from the misinformation effect.

The student describes the research design clearly and explains why it fits the investigation.

The student gives useful participant details, including age range, gender breakdown, and school context.

The student identifies the main materials and explains the role they play in controlling the procedure.

The sampling explanation would be stronger if the student explained how driving experience was handled rather than only noting that it may have varied.

The control of materials and language could be linked even more directly to the independent variable and internal validity.
