It probably is at mine. In fact, we're not supposed to access the internet for any personal use whatsoever. So obviously, my use of UKB is purely for the preparation and delivery of lessons. Currently my class are studying a unit looking at classic boulder problems of the Peak and North Wales, with a focus upon those between 7a and 7c this week. Since I work in a special school, the unit is differentiated according to the needs of my pupils and is much longer than is usual in a mainstream school. I reckon we'll be on this unit for the next year or more.
