A few years ago, a US study suggested that teachers should stop using red pens because the colour is associated with ‘warning, prohibition, caution, anger, embarrassment and being wrong’.
The research revealed that students think they’ve been assessed more harshly when their work is covered in red ink compared to other colours. It could even have a negative impact on teacher-student relationships and learning outcomes.
News of the report was met with ridicule by many, including Tory MP Bob Blackman who said: “It sounds to me like some petty edict which is nonsense. It is absolutely political correctness gone wild.”
