My school has about 700 students and about 50 teachers. We have two lunch periods, so we take turns when we can. We have no study periods and no free periods. We have library science students every period. Our classes have increased somewhat, and our circulation has increased.
Some classes come for only part of the period.
Video use has increased greatly, since the teachers need more things to do to vary their instruction. They also want us to order more videos, but the principal has nixed that idea. We don't keep the library open any longer than we did before. One problem has been getting the teachers to plan their library time to avoid conflicts with other teachers. I asked the English teachers to work out a schedule for term papers back in the summer, and they wouldn't.
