IB Economics HL Internal Assessment Example

The student includes relevant diagrams for all three commentaries, showing clear effort to integrate visual economic analysis.

The most successful diagrams do help signal the intended direction of change, especially in the macroeconomic and foreign-exchange sections.

Several diagrams are not accurately matched to the economics being discussed, especially the cartel/medicine figure and the inflation figure.

Some labels and numerical changes are inconsistent with the written analysis, which weakens the credibility of the visuals.

The explanations are often only partly connected to the actual diagram shown, so the reader cannot always see a clear line from graph to economic outcome.

The student uses a substantial range of relevant economic terminology across the portfolio.

Many terms are appropriate to the articles and help keep the commentaries economically focused.

Some key terms are used imprecisely or inconsistently, especially where the analysis shifts between related concepts such as deflation and disinflation.

At points, terminology is used in a way that does not match the model or mechanism being discussed, which reduces analytical precision.
