It would appear that Open Plan Classrooms (OPCs) are making a comeback. Or probably more accurately, they never really went away. You may have also heard of them being referred to as Modern Learning Environments (MLEs). I have no knowledge of their prevalence, past or present. But it is looking increasingly likely that your local school may be using, or planning to use this kind of space. So for that reason, I think it’s worth taking a look at what they are, and examine their potential impact on teaching and learning.
I don’t see how an open plan classroom could ever be worthwhile. Just ask anyone that has to work in an open area office.
