If you’re teaching mathematics, you might find these videos on how to teach students to write mathematics useful. These practical tips are presented by Kevin Houston (University of Leeds), Mike Robinson (Shefrield Hallam) and Franco Vivaldi (Queen Mary, University of London). As noted:
Students don’t write mathematics correctly. They throw down a mess of symbols with the answer underlined at the bottom and rely on the examiner’s intelligence to get the marks. Teaching them to write in a more orderly and logical way has numerous advantages: it makes marking easier; allows students to demonstrate understanding (or not); forces an improvement in their thinking skills. Expressing their ideas clearly and correctly is a valuable skill for graduates in further study, employment and life in general.
