The document provides guidance for students on writing an A2 essay that evaluates approaches to help close the global development gap. It discusses identifying relevant sources, structuring the essay, using evidence to support arguments, and understanding concepts. Students participate in activities to analyze sources for evidence of the development gap, causes, and actions taken. They discuss strategies seen in a video on Cambodia and themes in a reading on trade barriers and the rich-poor gap. The goal is to hone skills in observation, interpretation, and using evidence in essays.
