IB Geography HL Internal Assessment Example

The student poses a clear geographical investigation focused on a real coastal process at a named site.

The student links the question to relevant theory such as aeolian transport, vegetation stabilisation and dune succession.

The student identifies Mambrui precisely and provides enough locational detail to make the fieldwork feasible.

The student's maps include useful conventions such as titles, north arrows, keys and scales.

The maps have some spelling, labelling and source-acknowledgement issues that reduce clarity.

The specific transect used is not clearly identified on the local map.

The geographic context would be stronger with more detail on dune type, coastal exposure and human pressures.

The question includes variables that are not fully measured in the investigation, which limits how completely it can be answered.

The student chooses methods that are broadly suitable for a coastal transect investigation, especially the use of quadrats, pH readings and systematic sampling.

The student explains the pH procedure step by step, which makes the fieldwork easier to follow.

Using repeated readings and averages shows an attempt to improve reliability.

The transect approach is appropriate for comparing change across a dune system.

The method does not address all variables named in the question, especially wind speed and any direct measure of dune formation.

There are inconsistencies in the sampling intervals described versus the data later presented.

The pH procedure is not described in enough technical detail to show proper calibration and standardisation.

The number of trials reported is unclear, which weakens confidence in the reliability of the method description.
