Introduction Research has been undertaken to answer the following question: Can icon-based programming languagesbe used to teach first year programming concepts to undergraduate students more effectively than text-basedlanguages? 5 6 Many noted researchers (e.g. Glinert and Scanlan ) have empirically established the cognitive advantagewhich graphical methodologies provide over textual ones.

thedevelopment of an innovative delivery system. In 1993, a faculty committee consisting of representatives from various departments was formed by thedean to develop an “innovative curriculum” for the college. In carrying out the task, the committee consideredand used as reference several models from other institutions, including Drexel University’s “E4 EducationalProgram1” and the “Integrated, First Year Curriculum2” at Rose-Hulman Institute of Technology. The newengineering curriculum developed at the University of Miami had the following objectives: 1. Facilitate the transition of students from high school to college environment, 2. Expose students to engineering in their freshman year, 3. Make the study of mathematics, basic sciences

The goals of the curriculum are to provide (1) motivation andcontext for the fundamental material taught in the first-year mathematics and science courses; (2) arealistic and positive orientation to the engineering profession, and (3) training in the problem-solving, study,and communication skills that correlate with success in engineering school and equip individuals to belifelong learners.Curriculum Structure and Instructional Approach In the fall semester of 1994, IMPEC students took the first courses in calculus and physics(mechanics) as well as a one-credit engineering course.

The research done by Johnson addressed the technical and practical aspects of the serial interfacebetween a personal computer running CIManager and the Adept One robot running the V+ operating system.Multiple design alternatives were specified and evaluated by Johnson for the development of this AdeptOne/CIManager interface. This project was executed over a four-month period and resulted in thedevelopment of two separate programs - the Serial Interface Monitor (SIM) on the Adept robot and theADEPT 1 driver under CIManager.

University of South Alabama(USA) began, in Fall 1993, an evaluation of the undergraduate program to meet the challenge ofengineering education for the 21st Century. Restructuring of the mechanical engineering curriculum atUSA is also prompted by the changing ABET (Accreditation Board for Engineering and Technology)requirements for design. Under the current criteria, design is defined as "an experience that must grow withthe student's development," and "the design experience is developed and integrated throughout thecurriculum"1. In addition to the development of student creativity, formulation of design problemstatements and specifications, consideration of alternative solutions, and feasibility considerations, ABETsuggests that design should also

A more specific proposal defining a world-class engineer for the 21st century has been recently put forwardby the Penn State Center for Enhancement of Undergraduate Engineering Education. The following qualitieswere identified (Kearns et al., 1995) for this purpose:1. Aware of the World: sensitive to cultural-differences, environmental concerns, and ethical principles; alert to market opportunities.2. Solidly Grounded: thoroughly trained in the fundamentals of engineering and science; having a historical perspective of advances in science which can impact engineering prepared to continue life-long learning.3.

Delivery time is also critical since the student as we] 1 ascurrent and potential employers would like a degree in a reasonable time, or even in a minimum time. Asteachers we insist on our students achieving defined competencies before a degree is granted and thestudents and employers also require this, certainly when they are given professional responsibility. So inlearning and in facilitating student colleagues to do quality work we need deliberate processes to help us.

Since executive positions more often go to employees coming from thetechnical ranks, increasing the number of women who study engineering should also, over the long run, increasethe number of women executives in industry. The engineering profession and its image will be enhanced bygreater participation of women. It may become a more caring and balanced profession that considers the impact .of engineering designs and projects on society, the environment, and the health of individuals The abilities ofwomen cannot be ignored if this country is to solve its problems

Mathematical applications can be easily addressed in the classroom. When confrontedwith the cacophonous, grimy, economic reality, students learn to use science to understandproduction systems. On the factory floor all variables save one are not generally given. As thestudents overcome problems and analyses despite gaps in readily available data, the meaning ofengineering education takes hold. Solving meaningful problems amid the din is the bestexperience.

While this design provedexceptionally strong, the value of studying these hangars is in the changes that were made in the designbetween hangars no. 1 and 2. Construction of hangar no. 1 required extensive form work and welding ofthe reinforcing steel. With hangar no. 2 the roof members were prefabricated on the ground, lifted intoplace and then welded together. This system of prefabrication also produced exceptionally strong units.However, of importance in this study, the prefabrication allowed hangar no. 2 to be constructed at a costsubstantially lower than the cost of hangar no. 1.
