I teach first and second grade and I am also trying to improve
"craftsmanship", but many of my students come from homes where they have not had an
opportunity to learn to use media. I ask them if they colored over something
for a reason (if it involves water they will say the person is under water) or
if they were just trying to hurry.
Mostly I find that they have just never learned how to color in or around
things. I also try to insist that the entire page is colored. I only have 45
minutes of classtime which is about 15 to 30 minutes of drawing time. Even
so, if they rush through it I make them fix it or do it over so they don't get
free time to play. If they have to do it over a time or two, it usually
convinces them that I am serious and if I see that there is no improvement the
second time I talk to the classroom teacher and start looking for other reasons. I
have two students now that constantly rush through their work and may do the
assignment two or three times, but they are also doing that with their
classwork and may have some learning disabilities.
I am trying to find ways to help the kids critique their own work
(based on rubrics or simple criteria) but I just can't seem to schedule it all into
45 minutes. I am also concerned than some kids really can't do better and am
looking for ways that I can teach those skills.
Like Woody, I try to encourage all of them to do their best and not try
do things the same way as someone else, but it is the "doing their best" that I
am having a problem with.
Good luck, and let me know if you come across any new ideas that work,
