IB Mathematics Analysis and Approaches (AA) HL Internal Assessment Example

You present the investigation with a clear title page, introduction, methods, conclusion, and references, which makes the work easy to follow.

Your figures, captions, headings, and page numbering create a strong visual structure and help the reader move through the exploration smoothly.

Most of the content stays focused on the carafe’s capacity and supports the central aim of the investigation.

A few sections include more explanation than necessary, especially repeated formula descriptions and extended algebra.

Some parts of the argument would be clearer if repetitive worked details were compressed into tables or shorter summaries.

There are a few places where the flow weakens because later numerical reporting is not fully consistent with earlier calculations.

You use appropriate mathematical language and notation for most of the exploration, including coordinates, functions, integrals, units, and percentage error.

You make effective use of several representations, including photographs, annotated diagrams, regression plots, tables, and algebraic derivations.

Your communication is generally logical, with variables introduced before they are used and figures referenced where needed.

Some notation becomes crowded or difficult to follow when several similar boundary functions are introduced close together.

A few expressions are transcribed unclearly, which makes it harder for the reader to track exactly which curve or interval is being used.

The final summary would be stronger if every reported numerical result matched the values obtained earlier in the exploration.
