| 3-D Anatomical Models Are Most Effective for Educating In a recent study, retention of information about cataracts was compared, using four different educational tools: a three-dimensional anatomical model, a poster, a brochure and an audiovisual presentation. The same information was included with each method. Knowledge retention was significantly higher with a three dimensional model. The portion of respondents who answered twelve questions correctly was 95% for the anatomical model, 78% for the brochure, 72% for the audiovisual presentation and 71% for the poster. The percentage of correct responses is 22% to 34% higher with the three-dimensional anatomical model than with the other three learning tools. Without receiving any information prior to answering questions about cataracts, 44% of respondents, on average, answer each question correctly. The percentage of correct responses is 2.2 times greater after receiving information on cataracts. “Anatomical models are the most valuable means to explain, in a short period of time, what is relevant to the surgery or the disease for each patient.” Physicians Prefer 3-D Anatomical Models “With a three-dimensional structure, there is the ability to point to something, to hold something, which is not available in two dimensions.” Physicians Are Likely to Keep 3-D Anatomical Models Indefinitely “I’ve had the GPI anatomical model of an eye for about three years, and it’s like new. There isn’t any printing to rub off. It’s an educational device, and I’ll continue using it as long as I have all the parts or as long as it’s still relevant.”
