Integrated engineering workstations in electrical engineering laboratories

This paper provides a description of integrated engineering workstations (IEW’s) used in undergraduate electrical engineering laboratories. The IEW’s are used for the design, analysis, and testing of engineering systems. Examples of laboratory experiments and software programs are presented.

An Ethical History of Photography in Combat and of Combat Photography in the United States during World War II

With the United States‘ entry into the Second World War, the word ?censorship? was seen largely as antithetical to, rather than a necessary counterpart to, victory among Americans. People did not want to be censored in their writing, photographs or speech,but it proved to be necessary even before the war began, in order to protect government secrets and the people on the home-front from scenes that were too disturbing. Even before the war had officially begun, there were problems with censorship among journalists and newspapers. The initial response of outrage in reference to censorship in the United States was common among journalists, newspapers, magazines, and radio news; nevertheless, there was a necessity for censorship among Americans, on the home frontand the front lines, and it would be tolerated throughout the war to ensure that enemies of America did not gain access to information that would assist in a defeat of the United States in the Second World War. The research I have conducted has dealt with the censorship of combat photography during World War II, in conjunction with the ethics that were in play at the time that affected the censors. Through exploring the work of three combat photographers — Tony Vaccaro, James R. Stephens and Charles E. Sumners — I wasable to effectively construct an explanatory ethical history of these three men. Research on the censorship and effects it had on the United States brought me to three distinctareas of censorship and ethics that would be explored: (1) the restrictions and limitations enforced by the Office of Censorship, (2) a general overview of war and photography as it influenced the soldiers and their families on the home-front, (3) and the combat photographers and personal and military censorship that influenced their work. Although their work was censored both by the military and the government, these men saw the war in a different light that remained with them long after the battles and war had ceased.Using the narratives of Tony Vaccaro, Charles E. Sumners and James R. Stephens as means for more in depth research, this thesis strives to create lenses through which to view the history and ethics of censorship that shaped combat photography during the Second World War and the images to which we refer as representative of that war today.

The Impact of Gender and Pedagogy on the Development of Self-Regulated Learning Strategies in Undergraduate Engineering Classrooms

The purpose of this paper is to examine ways in which pedagogy and gender of instructor impact the development of self-regulated learning strategies as assessed by the Motivated Strategies for Learning Questionnaire (MSLQ) in male and female undergraduate engineering students. Pedagogy was operationalized as two general formats: lecture plus active learning techniques or problem-base/project-based learning. One hundred seventy-six students from four universities participated in the study. Within-group analyses found significant differences with regard to pedagogy, instructors’ gender, and student gender on the learning strategies and motivation subscales as operationalized by the MSLQ. Male and females students reported significant post-test differences with regard to the gender of instructor and the style of pedagogy. The results of this study showed a pattern where more positive responses for students of both genders were found with the same-gendered instructor. The results also suggested that male students responded more positively to project and problem-based courses with changes evidenced in motivation strategies and resource management. Female students showed decreases in resource management in these two types of courses. Further, female students reported increases in the lecture with active learning courses.

Effect of Participant Gender, Professor Gender, and Activity Interventions on the Understanding of Concepts in Thermodynamics

Misconceptions about heat and temperature have been seen across all educational levels, even in undergraduate engineering courses. One way these misconceptions can be remediated is through instructional methods, such as inquiry-based activities. Performance on assessments in sciences and engineering has been found to vary when gender is taken into consideration. The purpose of the current study was to investigate the effects of participant gender, professor gender, and level of inquiry-based activities on the conceptual understanding of 247 undergraduate engineering students in thermodynamics. A pre-test post-test design was used. Conceptual understanding of thermodynamics was measured by students’ scores on the Concept Inventory for Engineering Thermodynamics (CIET; Vigeant, Prince & Nottis, 2011). Inquiry-based activities were developed by the researchers and given to professors who determined if they would do all, some, or none of them as they taught. Significant differences were found among participants of different gender, different gender of the professor instructing the course, and level of inquiry-based activity. The participants who were exposed to all of the activities provided didsignificantly better on the post-test than those who were only exposed to some or none of the activities. The results from this current study indicated that differences in gender, professorgender, and level of inquiry-based activity has an effect on undergraduate engineering students’ conceptual understanding of thermodynamics. Future research should investigate more factorsthat contribute to lower representation of women in the engineering field.
