USE OF ULTRASOUND IMAGING EQUIPMENT IN CLASSROOM AS A TEACHING AID

摘要

The inventive process named SWITCH is a unique teaching aid for students and teachers of biology to help them better understand the basic concepts and remove the ambiguities left behind by traditional teaching methods. It utilizes a portable ultrasound machine in a class room setting to obtain real time images of internal organs of human/animal body and project them on a big screen while the audience watches. The images so produced are not only vivid and multidimensional but also carry information like organ size, shape, texture, position and physica l relationship to other organs in the body. In case of heart and blood vessels the real time images demonstrate exact function of chambers and valves and flow of blood in color from arterial to venous tree. The technique aims at fortifying truthful concepts of systems in a living body from the very basic to advanced levels of biology education. It has been developed in accordance wi th curricular guidelines for various levels and therefore has different modules dedicated to those levels (high school, colleges, universities, technical training institutes and other professional training institutions). Modules are based on chapters of respective recommended text books and can be utilized at the beginning, during or at the end of a chapter.
