Eight historical sources provide students with an avenue to sharpen their skills for the Source Study section of the ATAR course examination. The sources come from both key players of the revolution and from historians. As such students will have an opportunity to examine differing points of view or perspectives. A series of questions akin to the those posed in both Units 3 and 4 will be used to elicit higher order thinking. Finally, students are presented with three historians' perspectives on the February Revolution. This should give them an opportunity to address the concept of 'contestability' in history.
