Using a Nationwide Internet‐Based Bridge Design Contest as a Vehicle for Engineering Outreach

The West Point Bridge Design Contest is a nationwide competition intended to increase middle school and high school students' interest in engineering. Unique among national engineering competitions, it entails no cost to participants, is entirely Internet‐based, and is achievable by any student with a Web‐enabled computer. By leveraging information technology, a project team of just three people has provided an engaging engineering design experience to over 30,000 students in the past two years. The project receives financial and promotional support from the American Society of Civil Engineers and private industry. Feedback from contestants and teachers indicates that students' interest in engineering is positively affected by their participation in the contest.     

Identifying Factors Influencing Engineering Student Graduation: A Longitudinal and Cross‐Institutional Study

Pre‐existing factors are quantitatively evaluated as to their impact on engineering student success. This study uses a database of all engineering students at nine institutions from 1987 through 2002 (a total of 87,167 engineering students) and focuses on graduation in any of the engineering disciplines. We report graduation rate as a function of years since matriculation, and determine the typical time‐to‐graduation. A multiple logistic regression model is fitted to each institution's data to explore the relationship between graduation and demographic and academic characteristics. A pooled model is fitted to six institutions where a complete data set was available. High school GPA, gender, ethnicity, quantitative SAT scores, verbal SAT scores, and citizenship had significant impact on graduation. While HSGPA, SATQ were significant for all models tested, the significance of other predictors varied among institutions. These studies add to the existing body of research about factors affecting the success of engineering students.     

Influence of African American Engineering Student Perceptions of Campus Climate on Graduation Rates

African American undergraduate engineering student perceptions of institutional and personal/social campus climate factors were investigated to determine how these perceptions influence academic performance and institutional graduation rates. Data collection was accomplished through use of a quantitative and qualitative survey instrument administered to a national sample of subjects. The research discovered wide variation in individual institutional African American graduation rates and differences in rates among groups of institutions categorized by their academic selectivity or their designation as a Historically Black College and University. Students at institutions in the higher of the academic selectivity categories had higher graduation rates. However, students enrolled in the Historically Black Colleges and Universities category had more favorable perceptions of their college experience and had higher grades than students attending other institutions. After controlling for institution category, higher graduation rates were associated with students' lower perceptions of racism and discrimination and with students' greater institutional commitment.     

Gender and Ethnicity Differences in Freshmen Engineering Student Attitudes: A Cross‐Institutional Study*

We examine the attitudes of entering freshman engineering students and how they change over the course of the first year at 17 institutions. In addition to better understanding these attitudes and the changes that occur, we explore how these changes potentially affect such issues as “first term probation” and attrition from engineering programs. Particular attention is directed at isolating differences due to gender and ethnicity. Thirteen different student attitudes were captured using the Pittsburgh Freshman Engineering Attitude Survey© (PFEAS) at the beginning of the first semester (pre) and at either the end of the first semester or first academic year (post). Definite gender differences were found on the pre‐survey for five of the attitude measures. For all but one of these measures, female engineering students' initial attitudes were more negative than those of male students. Across the sample of institutions, female students consistently began their engineering studies with a lower confidence in background knowledge about engineering, their abilities to succeed in engineering, and their perceptions of how engineers contribute to society than did their male counterparts. However, those same female students were more comfortable with their study habits than were the male students. The post questionnaire data indicated that differences for three of these five attitude measures persisted. Most important, female engineering students continued to maintain a lower confidence in their abilities to succeed in engineering as compared to male engineering students. When the PFEAS data were mapped into EC 2000 outcomes, comparable cross‐institutional gender differences were observed that paralleled those found for the attitudinal measures. Because the number of minority students was relatively small, significant cross‐institutional differences between each minority cohort studied (African American, Asian Pacific, and Hispanic) and the majority cohort, similar cross‐institutional patterns could not be observed. However, possible trends were found between African American and majority students' attitudes for certain measures, while other attitudinal measures were found to be significant when Hispanic students were compared to majority students. Significant attitudinal differences between Asian Pacific and majority students were similar to those found between female and male engineering students. By knowing how attitudinal measures differ among gender and ethnic cohorts, and understanding how those differences relate to attrition from engineering programs, we can then developed more informed programmatic initiatives that can impact these attitude in a positive manner. As a result, we may be able to reduce engineering attrition, especially by underrepresented student cohorts.     

Developing and Assessing Students' Entrepreneurial Skills and Mind‐Set*

A primary goal of The Pennsylvania State University's new Engineering Entrepreneurship (E‐SHIP) Minor is to build students' life skills so they can succeed within innovative, product‐focused, cross‐disciplinary teams. The E‐SHIP Minor is designed for undergraduate students majoring in engineering, business, or IST (Information Sciences and Technology) who aspire to be innovation leaders for new technology‐based products and companies. This paper outlines five E‐SHIP program components to meet this mission: the core courses for the minor, E‐SHIP competitions in which students exhibit their products and ideas, the E‐SHIP Event Series, student organizations to support out‐of‐classroom entrepreneurial interest, and team projects for local industry and Penn State researchers. Penn State's engineering entrepreneurship program is reviewed, summarizing both quantitative and qualitative assessment data to date, previewing future assessment plans, and providing a summary of lessons learned during the development and implementation of this program.     

Women's Perceptions of the Climate in Engineering Technology Programs

A review of the literature shows that women learn and behave in ways that differ from the norm in engineering, science, and mathematics, but no research has been done specifically on women in engineering technology. In order to determine whether there is a difference between what women in engineering technology perceive as important to them and what exists in their academic programs, we conducted a survey of 100 female students from 2‐year and 4‐year schools throughout the country. Specifically, we were interested in their perceptions of competition and challenge, faculty support, recognition of their abilities, peer support, and inclusion in the program. The results showed significant differences between what was important to them and what they perceive exists in the program in all areas except competition and challenge. Differences were also found based upon demographic variables.     

National Aerospace Design Competitions: Industry/University Partnerships

This paper describes the growth of the individual and team national undergraduate and graduate AIAA/Industry design competitions. These design competitions have been developed primarily to enhance the university capstone design education experience of both undergraduate and graduate aerospace engineering programs. The competitions represent an Industry/University partnership to improve the design capability of individuals, corporations and the nation at large. The AIAA serves as the facilitator in this process. The student design teams respond to RFPs developed by AIAA Technical Committees. The competitions are funded by interested corporations. The AIAA design competition model or template could easily be implemented by any professional engineering society to nurture and encourage student capstone design efforts in that society's discipline. Students, corporations, the AIAA and the nation benefit from these competitions which enhance the competitiveness of all of the participants and thereby the competitiveness of the national community. The paper also includes an assessment of these competitions and some thought about their future direction.     

Gender Differences in Elements of the Undergraduate Experience that Influence Satisfaction with the Engineering Major and the Intent to Pursue Engineering as a Career

Background Groups within and outside of educational institutions are interested in factors that influence satisfaction among students enrolled in the engineering major as well as elements within the college environment that shape students' intentions to work in engineering in the future and whether these elements differ by gender. Purpose (Hypothesis ) This study identified gender differences on indicators of the undergraduate experience including faculty‐related and student‐related variables as well as measures of satisfaction with the institutional environment that are related to satisfaction with the engineering major and intent to pursue a career in engineering ten years from now. Design /Method The mixed methods approach used for this investigation involved nine institutions with engineering undergraduate degree programs. An online questionnaire was administered to undergraduate students enrolled in engineering. Qualitative data was collected through focus group interviews with students at each of the nine participating institutions. Results Findings reveal that satisfaction with the engineering major does not translate directly to pursuing a career in engineering, particularly among women. In terms of elements of the undergraduate experience, some types of interactions with faculty and peers have both short‐ and long‐term impacts on interest in engineering as a major and as a career. Conclusions Creating learning environments that emphasize care and respect for students as well as overseeing student interaction during group work can make a difference in students' satisfaction in the engineering major and in interest in engineering as a career, particularly for women.     

Study of Instructional Modes for Introductory Computing

The School of Engineering at Vanderbilt University requires all engineering students in their first semester to take a course that introduces computers in engineering. Two questions arise: is the best setting in which to teach this type of material either a combination of lecture and laboratory or all‐laboratory; and does a student‐owned laptop computer contribute more to learning? For two years the course was organized with these two different modes of instruction. For a third year the students learned in the all‐laboratory environment and 30 percent of the students used their own laptop computer. At the end of the semester an in‐depth questionnaire with quantitative ratings was given to the students to determine if there were differences in their learning preferences. Contingency tables were used to compare responses. There were several statistically significant differences in student responses favoring the all‐laboratory mode and students using laptop computers. Several of them are: the students are much more comfortable with computers at the end of the semester; either laboratory or working by oneself were the preferred settings for learning; and lecture was not a preferred setting for learning any topic.     

Evaluating the Effectiveness of Computer Tutorials Versus Traditional Lecturing in Accounting Topics

Colleges and universities are continually making efforts to incorporate computers and technology into the varied aspects of their teaching environments. However, it is difficult to distinguish the effectiveness of these machine tutors from their human counterparts. There has been much debate about technology‐based instructional strategies in learning environments. This article addresses one issue of that debate—the effectiveness of teaching undergraduate engineering students using computer‐mediated tutorials versus traditional lecturing. Specifically, this research compared student test scores using computer‐mediated accounting tutorials alone with those of students who received traditional lectures and computer‐mediated tutorials on the same topic. Statistical analyses were performed to determine which was a better instructional method. Based on previous research by the authors and other published research, it was hypothesized that both methods would be satisfactory instructional tools and yield similar educational results. The results indicate that there was no statistically significant difference between the two methods. This was consistent with previous studies. This study concludes that computer‐mediated tutorials could be substituted for traditional lectures without impacting what a student learns—at least for teaching accounting fundamentals.     

Student Performance and Acceptance of Instructional Technology: Comparing Technology‐Enhanced and Traditional Instruction for a Course in Statics

The College of Engineering at the University of Cincinnati has evaluated the use of instructional technologies to improve the learning process for students in fundamental engineering science courses. The goal of this effort was to both retain more students in engineering programs and improve student performance through appropriate use of technology. Four modes of instruction were used to teach an engineering fundamentals course in statics. A traditional instructor‐led course, a Web‐assisted course, a streaming media course, and an interactive video course were all presented using a common syllabus, homework, tests, and grading regimen. Evaluations of final course grades indicate that use of instructional technology improved student performance when compared with traditional teaching methods. Student satisfaction with technology varied considerably with the Web‐assisted format having the highest student approval rating of the technologies. The results indicate that time on task and interest in content can be improved through the appropriate use of technology.     

Introducing Middle School Students to Engineering Principles Using Educational Bridge Design Software

In an effort to motivate middle school students to consider future careers in engineering, an educational outreach program was developed and implemented during National Engineers Week. The outreach program concentrated on bridge engineering and was presented within one day to the entire eighth grade student population of the local public school system. The program began with a presentation on careers in engineering with a particular emphasis placed on bridge engineering. Fundamental engineering concepts used in bridge design were then explained. The students used these concepts to design a single‐span truss bridge using an educational bridge design software program. Finally, a bridge design competition was held in which the students attempted to optimize the design of their bridge.     

Enabling Engineering Performance Skills: A Program to Teach Communication,Leadership, and Teamwork*

A minor in Engineering Communication and Performance is being created at the University of Tennessee in conjunction with the engage Freshman Engineering Program. This minor provides engineering undergraduate students with formal training and a credential in complementary performance skills necessary for success in today's workplace. This interdisciplinary program is designed to improve the ability of engineering graduates to work on teams, to be effective communicators, to be socially adept, and to be prepared for leadership roles . Five courses compose the minor. Three of these courses are new and custom‐prepared for engineering students, while the other two may be selected from a limited list of courses that provide in‐depth training on supervision, cultural diversity, and interpersonal interaction. This multi‐disciplinary program takes a novel approach in the subject matter presentation and in the method of coaching students to use these skills. In the custom courses, students receive instruction and are placed in mini‐practicums. To complete the minor, students participate in a full practicum in a social service setting. This paper discusses assessment; course development; program basis and development; strategies for implementation of this new program; integration between engineering, counseling psychology, and human services; and student, faculty, and industry response to the program. The collaboration makes this program transportable to other institutions as it is dependent on having institution expertise in the disciplines of counseling and human services rather than having engineering educators with expertise in these fields. Our experience with establishing this collaboration will also be discussed.     

Teamed Internships in Environmental Engineering and Technology: A Project Report

This paper is a summary report of the “Teamed Internships Program” (TIP), an Advanced Technological Education (ATE) grant through the National Science Foundation (NSF). This three‐year project created internships encompassing regional industries, federal research facilities, and two‐ and four‐year educational institutions. The project cultivated teamwork and communication skills for environmental technician and engineering students, developed instructional materials, and provided valuable contacts with industry. To foster faculty and teacher enhancement and student interest in environmental science and technology, insights from the program were incorporated into instructional materials and educational modules for dissemination to local secondary schools.     

Outcomes of a Longitudinal Administration of the Persistence in Engineering Survey

Background Understanding more about student decisions to leave engineering may lead to higher retention. This study builds on the literature and focuses on the experiences of a cohort of students who aimed to complete their undergraduate work in 2007. Purpose (Hypothesis ) This paper presents the outcomes of the longitudinal administration of the Persistence in Engineering survey. The goal was to identify correlates of persistence in undergraduate engineering education and professional engineering practice. Design /Method The survey was administered seven times over four years to a cohort of students who had expressed interest in studying engineering. At the end of the study, the participants were categorized as persisters or non‐persisters. Repeated measures analysis of variance was used, in conjunction with other approaches, to test for differences between the groups. Results Persisters and non‐persisters did not differ significantly according to the majority of the constructs. Nevertheless, parental and high school mentor influences as a motivation to study engineering, as well as confidence in math and science skills, were identified as correlates of persistence. Intention to complete an engineering major was also a correlate of persistence; it appears to decline sharply at least two semesters prior to students leaving engineering. The findings also suggest that there might be differences among non‐persisters when they are further grouped by when they leave engineering. Conclusions Facilitating higher levels of mentor involvement before college might increase student motivation to study engineering, and also constitute a mechanism for fostering confidence in math and science skills. Since the intention to complete an engineering degree decreases well before students act, there may be opportunities for institutions to develop targeted interventions for students, and help them make informed decisions.     

The Challenge to Change: On Realizing the New Paradigm for Engineering Education

The new paradigm for engineering education goes beyond the need to keep students at the cutting edge of technology and calls for a better balance in the various areas of engineering school scholarship. There is considerable concern that perpetuation of the old paradigm by engineering schools will all but assure minor roles for engineers in the future as well as difficulty in adapting to the exigencies of the fast‐paced global marketplace. However, the transition from the old to the new paradigm will not be easy since many of our research‐intensive universities are faced with financial pressures while the wherewithal to make the change rests mostly with those who oppose the change in the first place. This situation, coupled with the fact that there is no “one‐size‐fits‐all” transition paradigm, represents the challenge to change. Still, a number of engineering schools have made significant changes and have developed innovative approaches in their undergraduate programs. Taken together, the proven methodologies and knowledge gained should make it possible for most engineering schools to devise revitalization programs that fit the context of their institution, its student body, faculty, and objectives. This paper argues for a study to assess the impact of the tools and methodologies developed by pace‐setting engineering schools and the NSF Engineering Education Coalitions to lay the foundation for future reform initiatives.     

Retention and Performance of Male and Female Engineering Students: An Examination of Academic and Environmental Variables

In the present article, we conducted an exploratory study of student persistence and performance in a key course in the engineering sequence (i.e., Statics). At issue was whether certain characteristics of students (i.e., their gender, SAT-math scores, GPA) and institutions (i.e., class size, percentage of female enrollment, gender of instructor) would be associated with higher levels of persistence and performance. Students from 48 sections of Statics from 17 institutions were included in the study (N = 4,993 males and 1,123 females). Within-gender analyses showed that the primary factors associated with persistence were GPAs and SAT-math scores. Between-gender analyses revealed that the size and direction of the gender gap in persistence varied across institutions. Factors associated with these variations included the selectivity of the institution and the relative level of female persistence.     

Motivating Students with Disabilities to Prepare for SEM Careers

The National Science Foundation funded the project Enabling SUCCESS (Enabling Students to Undertake the Challenge of Careers in Engineering and Science) at Louisiana Tech University beginning in 1996. The goals of this three‐year project were to: stimulate student interest in science, engineering, and mathematics (SEM); heighten the awareness among middle school students, their families, and their science teachers of the opportunities for persons with disabilities in these fields; and provide them with an understanding of the importance of career exploration and taking appropriate college preparatory courses in high school. The project at Louisiana Tech University built upon twenty years of experience in applying assistive technology to the needs of people with disabilities and a ten‐year history of national educational reform initiatives. The project staff included engineering and science professors, teacher educators, college students, practicing engineers and scientists with disabilities, and rehabilitation technology professionals. A unique feature of this project was its focus on middle school students (grades six through nine) with disabilities, their parents, and their teachers. Through on‐campus workshops and showcases, home science activities, and college student mentoring, the project sought to inform and motivate. This paper summarizes the major activities of the model project and the results of the three‐year effort.
