For example Schwartz, Lindgren and Lewis (2009, p. 57) argue that direct instruction “tends to focus students’ attention to the told-solution procedures, not problem situations, so students learn answers to a problem space they never come to understand”. With conventional approaches, students risk noticing only the eye-catching surface features of a problem and fail to recognise the structure beneath. As a result, they might not be prepared to transfer their knowledge and skills to new situations (Schwartz, Lindgren and Lewis, 2009).
