IB Geography SL Internal Assessment Example

The investigation question is clearly geographical and explicitly linked to the Bradshaw model, which gives the work a strong theoretical focus.

The location is precise and feasible for primary fieldwork, with a named river basin and mapped sampling sites that support investigation in the field.

The mapping is generally clear and convention-compliant, with locational maps that help the reader understand the study area.

The theoretical justification could be more precise about which Bradshaw-model assumptions are being tested and why the chosen setting is appropriate.

Some site labelling and numbering are not fully consistent across the document, which weakens the coherence of the location framework.

A few presentational issues, such as crowded labels and an awkwardly orientated map, reduce clarity even though the overall mapping is adequate.

The methods are described in a detailed and largely replicable way, including width, depth, velocity, gradient, and wetted-perimeter techniques.

The methods are clearly linked to the research question and to downstream change, rather than being a simple equipment list.

The use of repeats and systematic site progression shows an understanding of how to gather comparative field data.

The methodology contains internal inconsistencies, especially the mismatch between six and ten sites, which weakens confidence in the sampling design.

Some procedural details are incomplete, such as the exact calculation steps for processed variables and the full depth-sampling procedure.

The description does not fully demonstrate reliability at the highest level because raw readings, uncertainty, and repeat data are not clearly presented.
