The ACF parameters of thesetwo signals are found to be quite higher than that of the other signals. This can be related to the vehicleacoustics. With regard to the temporal aspects of vehicle acoustics, reflected signal with various delaysand amplitudes superimpose the direct signal inside the vehicle. The effective duration ( τ e ) of the ACFcan reveal the characteristic temporal aspects of vehicle acoustics.4. ConclusionIn this paper, we studied the acoustical

of engineering is quite difficult. Thesurvey data reflects the students’ perceptions of their understanding more so than it does their actualunderstanding. However, it can be argued that the students’ perceptions of their levels of understandingof engineering are crucial to their abilities to make important decisions early in their engineering careers.Perception of understanding leads to confidence in decision making. Therefore, a student who believeshe understands engineering is more likely to be comfortable with the decisions he makes in engineeringthan is someone who does not believe he has an adequate understanding of engineering. Although somemay say that a more holistic view of engineering is preferable to a compartmentalized view, the

. The group also demonstrated a lot of cognitive and superficial elaboration as well. This group outperformed the passive superficial group on both near (p=0.1) and far transfer (p=0.05).In our study, homework problems are similar to worked examples. The exams, which make up80% of the final grade, tend to look like homework problems; therefore final grades may be usedas a rough indicator of near transfer. The concept inventories represent far transfer tests sincethey require a more conceptual understanding. • The Help Seekers reflect the active meta-cognitive group.

The post-WWII and Sputnikeras saw a massive influx of federal support for research in higher education, increased hiring ofresearch-oriented faculty members, and curriculum revisions that reflected faculty members'interests. By 2000, engineering education looked more like that in a traditional science than in aprofession.3 Government, business, and professional societies pressed for engineering educationreforms in order to sustain America's technological and economic leadership.

sophomores who left engineering found that the most important reasoncited for women and second most important for men was that the “reason for choosingthe major was found inappropriate”. In other words, a significant number of studentswere not retained because they no longer felt engineering offered interesting work ormany job opportunities. Thus, retention of engineering students may be improved byplacing the freshman and sophomore curriculum more in the context of true engineeringwhere they can see these opportunities. Efforts across the nation to enhance theengineering experience in freshmen courses by adding design and/or project basedcomponents are a reflection of this effort.11, 12 Assessment has shown that introducingdesign and project based

Decrying suchinequity, efforts increased from the late 1960’s and early 1970’s to educate and train minoritystudents in the technical fields. To that end, one would be hard pressed to find a higher educationinstitution that had not developed some sort of program to support minority students’ STEMparticipation1. Though the rate at which students seek to study STEM is increasingly comparableby race/ethnicity, the rate of students graduating with STEM degrees is still disparate2 3 4.
