The visual and verbal as modes to express understanding of the human body

In this study, students' expression of understanding of structure and function in three systems of the body through visual (drawn) and verbal (written and spoken) modes was probed. Those with good comprehension had high scores in both modes. Pedagogical practices must emphasise explicit use of drawings and words to link structure and function concepts. This can help students of lower ability to form an integrated mental model which will aid understanding and expression.
