The final part of the process was to use the completed diagrams as an essay plan. I photographed each of the diagrams and shared them with the students. Their task was to use the diagrams as the basis of their essay on “Why did Stalin become leader of the USSR?”. Each paragraph was to focus on separate categories of hexagons, and the points made in each paragraph should have some logical order and ‘flow’. Moreover, the order of the paragraphs should be dictated by the arrows linking the categories, with the opening sentence of each paragraph after the first one being based on the explanation over each arrow.
