yes - nursery may be a waste of time, but as a teacher myself I see how much "work" gets done. I believe that there are benefits to "play" that are overlooked by parents do not see the educational value of it...YES, there are benefits to play...belows a short article I read regarding this topic...
Developing through play
CHILDWISE by RUTH LIEW
PLAY is fun. Children need to play as much as they need food, shelter and clean air. Children do not need to cram their minds with information. When they play, they learn to be resourceful and seek out the right kind of information for use in their play.
In many homes today, children have more toys than their parents ever did but sadly, the toys are mostly remote-controlled or high-tech in nature. The places they play in are limited and structured. By the time they reach school age, children play only games arranged by their schools or clubs. They hardly make up their own games or play freely with their friends.
Play spaces at home, usually arranged by adults, have stuffed animals, board games and store-bought toys all kept in plastic storage boxes. Some, kept high up on the shelves, are inaccessible to young children. They have to rely on adults to get the toys. When adults take over what children can do for themselves, they will lose opportunities to be creative and imaginative.
Unfortunately I think it is the system that is making us all nervous and uptight about sending our kids early to school....unfortunately from the schools point of view, they find it much easier to screen applications (some schools have over 200 applications for 10 spots) than interview each student, that's simply not possible. This is the easiest for them. Therefore, unless the culture of the schools change, there is really not much us parents can do but to make sure our kids are given the best chance to get into a school that fits their learning type. Would I send my 2 year old to a nursery? From a teachers point of view, yes. Would I take my kid out of school to leave for a family vacation? Probably. Would I question the amount of learning at the school? No because learning does not only happen within a school setting. But, then, why send your child to school, isn't that ironic? Yes, but society is built that way and to not follow the norm puts you at a disadvantage, to me it's as plain simple as that.
