Has any educator tried the Left Brain Vs Right Brain teaching methodology on his students?

Yes, for teaching to draw, i use a right brain teaching methodology and the students increase the creativity on their work.

Thank you for answering. At least someone shares my experience in that field. I personally used it in teaching Digital Media. It helped me evaluate the student's level of creativity versus innovation. It was an extremely successful method through which my students became the first awarded in the whole university.
