different reason not tied to lack of resources: found a major better suited to their interests, decided to pursue another career or life opportunity, did not develop a strong engineering identity, etc.ConclusionsOverall this paper was a data driven approach to understand how SES impacts studentpersistance and performance through the aerospace engineering curriculum at a large R1university. We found that students from low SES backgrounds struggled more in calculus andearly aerospace classes, left the major at a higher rate, and had lower 6-year graduation ratescompared to students from high SES backgrounds. The admissions criteria at this universitysuggests that students come in with a strong math background. Students from low

soon as the test is over or the course is completed, the students often just forget the material since they have no reason to retain the compartmentalized, modularized material.Subjects that are separate in the curriculum, such as thermodynamics and mechanical design, areintegrated in practice, since thermal and mechanical systems must function cohesively in realmechanical systems (e.g. an air conditioner). With this in mind, we propose to implement anovel, potentially transformative approach to integrating coursework through five semesters ofthe core mechanical engineering curriculum. The proposed work will test two hypotheses: 1. A long-term design project that integrates knowledge from multiple courses strengthens student

To meet thisgoal, we propose a curriculum development in the electrical engineering technology programdigital logic design series. Faculty involved in developing and teaching the new curriculum mustbe well-informed of advances in technology currently used in industry. Likewise, industry wantsto have qualified and well-educated employees coming out of academia who are ready toimplement their knowledge on day one of their employment. As a result, while academia needsto be fully aware of the current state-of-the-art knowledge requirements, industry must be driving

among students. Simultaneously, the level of trust in public and private institutions, interms of the honesty and integrity of those in leadership, is dwindling. For engineers, whoseoccupation allows them potential for positive or negative societal impacts, it is critical that theirdecisions involve sound ethical judgment. Despite this obvious need, the amount of time given toethics in an engineering curriculum is minimal. With all the knowledge and skills needed inengineering, it seems as if there is neither time nor space to teach ethics.Consequently, the results are predictable. During a recent meeting of engineering students,the students were asked what kinds of ethical questions they encountered at work or intheir studies. The majority

Ultimately, the productof the SAGE process is an improved curriculum. We contrast this with the engineering designprocess, which can involve development of new products rather than improving and evolvingexisting ones. As such, the SAGE process assumes that a degree program has already beenestablished and that objectives, outcomes, and topics for courses within the curriculum have beendefined. Ideally, the program uses a standardized style for documenting course syllabi as wouldbe exemplified by templates used for

An inability to recall previously learned knowledge is a symptom of anunderlying problem: a lack of effective understanding of engineering concepts and principles tothen see their application in a new context. In other words, the connections between concepts andapplications are weak. To address this underlying problem, civil engineering students at the USMilitary Academy at West Point were required to solve review problems on each homeworkassignment in two civil engineering design courses. This paper describes the theoreticalunderpinnings of these assignments and their implementation.
