Denoting read vs unread posts in classroom discussion

In coursework where you are required to write a reflection and post that reflection on and then reply to people's comments on your post as well as reply to other people's post, is there a way of removing/eliminating/denoting which  posts/comments you have already replied to? In a class of 60 people, if each person must post a reflection and then we are required to comment on all 60 reflections plus people's comments on our reflection, it is hard to keep track of what one has already read and what one has already commented on. It would be great if there was a way to denote the ones that haven't been read yet, maybe have them be highlighted or bolder (like office email) as opposed to the ones that have been read which are lighter in shade or not highlighted. If this is already doable, can someone point me in the right direction because I have not been able to find this feature.
