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 andteachers of biologyto help them better understand the basic concepts and remove the ambiguitiesleft behind bytraditional teaching methods. It utilizes a portable ultrasound machine in aclass room setting toobtain real time images of internal organs of human/animal body and projectthem on a big screenwhile the audience watches. The images so produced are not only vivid andmultidimensional butalso carry information like organ size, shape, texture, position and physicalrelationship to otherorgans in the body. In case of heart and blood vessels the real time imagesdemonstrate exactfunction of chambers and valves and flow of blood in color from arterial tovenous tree. Thetechnique aims at fortifying truthful concepts of systems in a living bodyfrom the very basic toadvanced levels of biology education. It has been developed in accordance withcurricularguidelines for various levels and therefore has different modules dedicated tothose levels (highschool, colleges, universities, technical training institutes and otherprofessional traininginstitutions). Modules are based on chapters of respective recommended textbooks and can beutilized at the beginning, during or at the end of a chapter.
