I have recently begun working for an agency in my local area and have thus far been posted to three different secondary schools. I have enjoyed the challenge of "hitting the ground running", being welcomed by the cover manager, given a copy of the school's policies, and thrown straight into the classroom, sometimes teaching every year group throughout the day, and almost always with classes of 30 students of more. In most cases, lesson plans and worksheets have been left for me to use throughout the day and I work through these diligently with the students, sometimes even picking up text books and learning/revising the topic quickly, so that I can help students or explain things more clearly (e.g. I re-learned how to find the nth term in maths the other day!) My question is how to deal with marking. From my point of view, I'm not really paid enough to do the marking, especially when I've taught 150 students throughout the day. On top of this, I am not usually a subject specialist and so I do not feel competent to mark the students' work (I worry that I may mark something as correct, when in fact it is incorrect). Indeed, many classes start with a 'Do Now' task, and I sometimes have to rely on students being correct, as I personally do not know the answers and the teacher has not included them in the PowerPoint. If I was to mark the students work, I'd therefore have to read through their work alongside module revision guides in order to determine whether their work is correct. When covering a recent English lesson, the students had to write an essay based on a novel they had read. In this instance, it would have been extremely difficult for me to mark the work, as I am personally unfamiliar with the novel and so any feedback I provided would be of no particular benefit to the student in terms of relating to the novel. So, the general rule seems to be that supply teachers should mark books. I would like to know how many of you actually do this? I understand that in a long-term role, it comes with the territory of essentially fulfilling the role of a permanent staff member, but what about when we undertake short-term roles (one or two days at one school, then a couple of days at another, etc.)?
