The knowledge of the mechanical properties of polymers and other materials is essential for several tasks in the field of materials science, like component design and material development. The tensile test is one method of determining many of the material's most defining mechanical characteristics. However, the teaching of laboratory experiments…

A series of computer programs designed to provide a dynamic simulator of Joyce and Weil's models of interactive teaching are described. Initially developed and tested at the City University of New York (CUNY), the system is capable of supporting retrospective and predictive analysis of selected kinds and patterns of verbal behavior in a variety of…
