This paperaddresses a follow-on question; does including these on-demand videos improve studentperformance and retention in the longer term? To investigate this hypothesis, Video AI wasmade available in Statics-Strengths in the spring of 2008, student use was tracked, and a simpleevaluation instrument (quiz) was deployed at the beginning of Mechanics of Materials(Mechanics), which was

Pre-requisite knowledge test in Statics is given at thebeginning of the course to reinstate the importance of understanding of free bodydiagrams. Thus, the Machine Design course deals more with application of the theory andconcepts learned in the mechanics sequence, namely, equilibrium of rigid bodies and freebody diagrams to design and/or to select mechanical components. Design standards (suchas ANSI, AGMA, etc.) are used in depth in this course and the students are

Mechanics course (Fall semester 1998) at the United States Air ForceAcademy was used as a testing ground for introducing and assessing the effectiveness of visualand hands-on learning aids using photoelastic materials and the finite element method (FEM).The course combines statics and strength of materials at an introductory level for all studentsregardless of major. Typically, the concepts of stress caused in objects by torsion, bending, andcombined loading are among the most difficult for students to grasp. For these topics, “enhancedlearning modules” were developed to bring visualization and hands-on learning aids into theclassroom experience. A complete description of these special modules is presented in thecontext of a learning styles

Although many students at thesecolleges usually take FEA as seniors, there are a few graduate students at Kettering who take thisclass. Some of whom are on-campus while few others are off campus (distance learning)students.

This also requiredrealignment of the existing electrical engineering program.Some of the key principles in the design and offering of the new program were: • Commonality as much as possible for courses and laboratories between mechanical and electrical engineering. An example of this is the concentration in robotics, an area in which students in both majors jointly take coursework. Other examples are controls and materials science. • Sharing of equipment with an existing industrial technology program. This provided immediate access to CAD laboratories with appropriate software, PLC- based mechanical systems and an automated

Other projects focused on developing curricular orrecruiting materials attractive to women and men. This paper will discuss the results and lessonslearned in the various programs.IntroductionDespite some progress toward equality in engineering, women remain underrepresented [1],especially in mechanical and electrical engineering, which are two of the largest disciplines. Onereason for the lack of women in these fields is that more women than men change their major toa non-engineering field after beginning college [1], and many students hold inaccurate views ofengineers and engineering [2] that discourage them from entering the

, not realizing thatin today’s world high school physics classes most closely resembles mechanical engineeringpractice, not modern theoretical physics.Many students respond in a reasonable way to this uncertainty - by seeking admission inthe undeclared category and hoping to decide on their ultimate path once at the university.But, of course, most of their first courses will consist of required background material inscience and math - not engineering. And the danger here is that students may opt out ofthe engineering track before they have really had a chance to experience it.Thus our departments face a two-fold challenge with regard to lower division students.
