IB Mathematics Applications & Interpretation (AI) HL Internal Assessment Example

The student's exploration has a clear overall progression from data collection to modelling, interpretation, and conclusion.

The student organizes the work in a way that is easy to follow, with clear sections and a logical sequence.

The student keeps most of the content focused on the investigation and the final question.

Some claims in the conclusion would be stronger if they were supported by numerical evidence rather than description alone.

A few formatting and structure issues interrupt the flow, such as repeated numbering and an extra blank page.

Some lengthy calculations could be moved more fully into the appendix to keep the main argument tighter.

The student uses mathematical language and notation appropriately in most places, including regression, logarithms, determinants, and differential equations.

The student includes several clear representations, such as tables, graphs, algebraic work, and the final model.

The student's writing is usually clear enough that the reader can follow the mathematics and the prediction being made.

There are some notation and terminology inconsistencies, especially around the cooling constant and the use of transformed variables.

The graphs would communicate more effectively with clearer labels, legends, and less visual clutter.

A few unit and wording slips reduce precision and make the mathematics less consistent than it should be.
