IB World Studies SL Extended Essay Example

The topic and research question are communicated clearly and maintained consistently throughout, with strong sign-posting and appropriate World Studies framing.

Methodology is comprehensive and informed: the mixed-methods approach (Python simulations, satellite/GCM data, literature synthesis) is well-described and suited to the question.

Frequent section headings, a contents page and linking phrases ensure the focus is never lost, demonstrating expert planning and execution.

Justification of some key design choices (e.g. linear albedo decline, dataset selection criteria) is asserted rather than fully justified.

Quantitative uncertainty analysis (RMSE, confidence limits) is acknowledged but not implemented.

Minor breadth in scope (mixing global GCMs, ABMs, machine-learning contexts) slightly dilutes razor-sharp focus.

Source material is expertly chosen: peer-reviewed journals, IPCC AR6, NASA/NSIDC datasets and primary code outputs form a robust, discipline-relevant basis.

Knowledge of physics and computer-science concepts is coherently integrated and applied to interpret both primary and secondary data.

Terminology and specialized concepts (e.g. radiative forcing, ensemble spread, agent-based modelling) are used accurately and consistently throughout.

A small number of weaker, non-scholarly visuals (e.g. wiki and forum images) detract slightly from overall scholarly rigor.

Some key theoretical concepts (e.g. Stefan–Boltzmann’s Law, Hadley cell circulation) lack formal citation.

Minor inconsistencies in defining variables (Q_reflected vs Q_absorbed) and in source credibility could be tightened.
