Many recent high-tech applications such as optical fiberfor high-speed communication or dielectrics in microelectronics also exploit some such qualities,but these are neither necessary nor sufficient attributes for a material to be called as glass. Ageneral definition of glass is that it is 'a solid with liquid like structure', 'a noncrystalline solid' orsimply 'an amorphous solid'. 1 None of these definitions is very helpful to typical engineeringstudents, even the ones majoring in Materials Science and Engineering, so that they canappreciate the characteristics of this important class of material. Clearly, an experimentaldemonstration of the essential features of

In instances that engineers are involved withenhancement and development of pre-existing programs, the size and complexity of aparticular program may become overwhelming. Universities are preparing the students tocope with the challenges that they are encountering in their work environment in thecontext of simulation and modeling. Different tools may be adopted in variousdepartments for training the students in programming such as C, C ++, Basic, Visual Basic,Fortran, or Matlab, etc. Some departments are facing the question of what environmentto adopt to train the students. Many departments have incorporated Matlab in some oftheir courses. References [1-3] are a few among

for staticinterference, and to produce assembly drawings. In general, CAD assembly models don’t move.Turning CAD models into mechanism modelsOnce a CAD assembly model is created, it is straightforward to extend this to a kinematic ordynamic model. Some CAD systems have this capability built in, and others use third-partysoftware. The procedure below is based on Dynamic Designer, but other software would requiresimilar steps. 1) Specify units and gravityThe first step is to specify the units, and to define the gravitational field. Gravitationalacceleration can be turned on and off, and its direction and magnitude can be specified. 2) Specify ground and moving partsA mechanism is composed of parts that are grounded, and parts that move.

This desirability is expected to increase further now that ABET accreditationprovides a reference point for those not familiar with EP.Before changing to EP, the Physics program at UW-P had several tracks: a major in physics,with or without an emphasis in engineering or education, and a minor in physics with anemphasis in arts and sciences or education.

To emphasize the need for students to reflect on thesequestions and come up with their own thoughts, the essays were to be written without referenceto any materials and without discussion with others. The students were given one week to writethe essay, and it was due on the day that discussion of these topics began in class. Some quotesfrom the essays that capture the main themes are presented in Table 1.The sophistication and clarity of the students’ definitions of engineering were
