I agree that teaching "critical" drawing is important; in fact, I begin teaching
drawing from observation with first grade students.
I'm wondering if the statements you made:
("Critical" DRAWING involving "careful judgement
or judicious evaluation" neither of which are
consistently employed in the public school
system, especially in grades K through 8. Children
are continually allowed to draw and paint in any
fashion they wish under the guise of "creativity."
In fact, many high school teachers draw as
they did in grade school; good or bad; the point
is - that by looking at elementary and secondary
classroom efforts in general, (visually) indicates
a decided lack of instruction in "critical"
come from some studies you have read or conducted, or if they are just
generalizations based on some of your personal observations.
I'm also wondering if you advocate using Nicolaides text with K-8 students.?
