Worksheets a no no?

So this is what I learned in school tonight, it is a big no no to use worksheets on children who are not of school age. I was shocked when she said this was taught in credentials class.  I wasn't told this in my credentials class.  Without trying to remember word for word how she explained it, I found this list of reasons online.  I'll post the source link below it.
Worksheets – A Big No-No!
HERE ARE THE MAIN OBJECTIONS TO USING WORKSHEETS WITH CHILDREN
UNDER KINDERGARTEN LEVEL
1. Children this age do not understand abstract concepts well. Letters, numbers and shapes
on a piece of paper are abstract symbols representing something else that is real.
2. Children learn basic concepts by using all their senses, by manipulating objects. They
will not learn anything new with worksheets. At most worksheets will provide drill for
concepts already learned.”
3. Children under kindergarten age don’t have the fine motor control within the lines; do
many of the other tasks often asked on typical worksheets.
4. “Seat Work” --- Sitting at a table is hard enough for kindergarten and first grade students.
Younger children have a shorter attention span and find it difficult to sit still for more
than a few minutes at a time.
5. Worksheets are not fun, not for long anyway. As soon as fascination of “playing school”
wears off they become drudgery. (Think back to your own days in elementary school.)
We want to make children eager, enthusiastic learners, not people who avoid learning
situations.
6. Worksheets do not develop creativity. In some cases they may actively inhibit the
creative process in children. When children are given patterns to copy or in color in, they
become less likely to come up with their own way of drawing things.
7. Teachers sometimes use worksheets merely to “occupy” children… to use up time.
There are so many better things children can be doing with their own time!
In November 1984 issue of Young Children (NAEYC), Carol Seefelt says “Asking children to
complete worksheets may be a form of stealing. Every time children are asked to fill-in
worksheets they are being robbed of opportunities to think and learn by doing.” http://www.southwest.tn.edu/childcare/parent_handbook.pdf

This really got me to thinking about how we have stifled the creativity of our children with all the worksheets and testing! So what's your thoughts?
