- The memory PowerPoint and the Curtis videos on memory offer some interesting real life situations, which could provide the basis for knowledge questions. Which knowledge questions on the topic of 'memory' can you come up with? Remember that knowledge questions should be open ended questions on the notion of knowledge. Knowledge questions often start with expressions such as 'To what extent...', 'How....', 'On what basis...', 'What counts as evidence...', 'What does it mean to...', 'What is the scope of/are the limitations of...', 'How can we be sure...?', 'How can we measure/distinguish...?' Knowledge questions are centred around what counts as knowledge, how we can use models to predict outcomes, whether it is possible to come up with a universal 'truth' in an area of knowledge etc.
