Well, I certainly believe that drawing can be learned, if it is taught correctly.
For 9 years, and 41 classes, I taught a class in oil painting at our local recreation center. It was an adult class. The first evening of class I always had the students draw a "grid" on their canvas with charcoal pencil. It was a simple grid with a vertical centerline, a horizontal centerline, and a cross, drawn from corner to corner.
I also furnished each student with a proportional, color photo upon which I had also Photoshopped the same grid.
Following the photo that had the grid on it, I taught students how to seek out "key points", and locations that were positioned logically by the grid, and from there, we drew a relatively useful depiction of the photo on the canvas.
Thinking back now, after 9 years, and 41 classes, I never had even one student who claimed that he/she "couldn't draw". They all did relaltively well, and all my students created drawings that were appropriate for using as a guide for painting.
I think the reason that my students were able to grasp the whole "drawing concept", and to perform in such a matter-of-fact way is that I never told any of them that it was supposed to be considered "difficult". I just showed them how to do it, and they followed along, believing that this was sorta' something that would work out if they did exactly as I was suggesting.
It worked for me. However, I had much more difficulty getting students to perform as well at applying paint, but the drawing operation always went rather well, as I recall.
