"Teachers have been told to stop marking schoolchildren's work with red pen because it is an "aggressive" colour. Queensland's Deputy Opposition Leader Mark McArdle told parliament today that teachers were being advised to reconsider their pen choice because it may offend children. Mr McArdle tabled a Queensland Health document proposing "strategies for addressing mental health wellbeing in any classroom". It says: "Don't mark in a red pen (which can be seen as aggressive) - use a different colour."" (AAP).
