Abstract
This educational device has been specifically developed so that a severely mentally disabled person can build simple and compound machines that are used in the teaching of basic mechanics. The four elements-building units, linkages, connector-strips and a special supporting base called a linkage-box, are capable of being united even though the disabled person may also have severe physical disabilties in hand and arm movements. As the machines are built, the disabled person is also having a three dimensional real life experience with concepts such as, 'force', 'weight', 'mechanical advantage', pulley, wheel, axle, velocity, rotation, directionality and cause and effect relationships. The knowledge and skills developed can also find practical application in the vocational, residential and recreational settings.
