Sustainability issues are increasingly important in engineering work all over the world. This article explores systematic differences in self-assessed competencies, interests, importance, engagement and practices of newly enrolled engineering students in Denmark in relation to environmental and non-environmental sustainability issues. The empirical base of the article is a nation-wide, web-based survey sent to all newly enrolled engineering students in Denmark commencing their education in the fall term 2010. The response rate was 46%. The survey focused on a variety of different aspects of what can be conceived as sustainability. By means of cluster analysis, three engineering student approaches to sustainability are identified and described. The article provides knowledge on the different prerequisites of engineering students in relation to the role of sustainability in engineering. This information is important input to educators trying to target new engineering students and contribute to the provision of engineers equipped to meet sustainability challenges. 相似文献

ABSTRACTThe purpose of this study was to examine community college engineering students’ perceptions of their classroom climate and how these perceptions are related to fundamental skills in engineering. The study was guided by the following research question: How are community college engineering students’ perceptions of their fundamental engineering skills related to their perceptions of classroom climate? Data from a 2009 National Science Foundation sponsored project, Prototype to Production: Processes and Conditions for Preparing the Engineer of 2020 (P2P), which contains information from students in 15 pre-engineering community college programs, were examined. Measures of classroom climate and fundamental skills related to engineering were first established through an exploratory factor analysis. In order to explore differences in student perceptions by individual characteristics and by institution, hierarchical linear modeling (HLM) was used. Results indicated that for community college engineering students, a warmer perception of classroom climate was associated with a higher perception of fundamental engineering skills. At community colleges, class sizes are generally smaller, especially compared to introductory courses at universities, and may provide a warmer climate for students considering beginning their engineering degrees. Given the diversity within community colleges, these institutions may provide an important pathway for underrepresented groups in engineering. 相似文献

GIS-Based Simulation of Engineering Construction Schedule 总被引：1，自引：0，他引：1
For its complexity, engineering construction schedule design is limited by various factors. Simulation-based engineering construction schedule takes critical path method （ CPM ） network as frame and calls complex cyclic operation network （CYCLONE） simulation model enclosed in advance for its simulation nodes. CYCLONE simulation model takes charge of simulating stochastic duration of activity and efficiency of resources, while CPM model performs project scheduling. This combination avoids the shortcomings of both models. Furthermore. geographic information system （ GIS ） technique is utilized to visualize the construction processes which are otherwise difficult to be understood by static results described. Application in practical project verifies the feasibility and advantage of the technique. 相似文献

Students’ perceptions of engineering have been documented through studies involving interviews, surveys, and word associations
that take a direct approach to asking students about various aspects of their understanding of engineering. Research on perceptions
of engineering rarely focuses on how students would portray engineering to others. First-year engineering student teams proposed
a museum exhibit, targeted to middle school students, to explore the question “What is engineering?” The proposals took the
form of a poster. The overarching research question focuses on how these students would portray engineering to middle school
students as seen through their museum exhibit proposals. A preliminary analysis was done on 357 posters to determine the overall
engineering themes for the proposed museum exhibits. Forty of these posters were selected and, using open coding, more thoroughly
analyzed to learn what artifacts/objects, concepts, and skills student teams associate with engineering. These posters were
also analyzed to determine if there were any differences by gender composition of the student teams. Building, designing,
and teamwork are skills the first-year engineering students link to engineering. Regarding artifacts, students mentioned those
related to transportation and structures most often. All-male teams were more likely to focus on the idea of space and to
mention teamwork and designing as engineering skills; equal-gender teams were more likely to focus on the multidisciplinary
aspect of engineering. This analysis of student teams’ proposals provides baseline data, positioning instructors to develop
and assess instructional interventions that stretch students’ self-exploration of engineering. 相似文献

This article describes the effort undertaken at the University of Iowa to institute a software engineering curriculum at the graduate level. Specifically, the article presents the experiences over 2 years in developing a pilot 2‐semester course in object‐oriented software engineering. This pilot course had the goal of introducing practical and realistic object‐oriented software engineering to students, and developed several innovative techniques to achieve this goal on a very limited budget. Students were exposed to realistic software engineering phases, processes and methodologies in developing real‐world software. This pilot course has culminated in a Master of Science subtrack in Software Engineering offered cooperatively by the Departments of Computer Science and Electrical and Computer Engineering at the University of Iowa, which made its debut in the Fall of the 1992/1993 academic year. 相似文献

A round 60% of useful energy is wasted in industry, homes, or transportation. Therefore, there has been increasing attention on thermoelectric materials for their ability to harvest waste heat into useful energy. The efficiency of a thermoelectric material depends on its electrical conductivity, Seebeck coefficient, and thermal conductivity in a conflicting manner which results in efficiency optimization challenges. Single crystals and polycrystalline layered materials have comparatively better ... 相似文献

To describe the spatial tendency and complex relationship of geological structures, a digital modeling based on geographic information system and the visualization of hydroelectric engineering geology information are presented. The functions of information visual query, spatial cutting, section drawing, and coupled analysis with hydraulic structures are realized. The geologic model can match the attribute data with the shape data of geological structures, and organize the information for spatial query and analysis of the 3D model. With an application in Laxiwa hydroelectric project on the upriver of Huanghe River, the method provides a 3D parallel section view and query results of geoinformation, and 3D section views of geoinformation along axis of spillway tunnel,and along the 5th axis with underground structures, respectively. 相似文献

This paper assesses whether cost engineering is an academic discipline or not. Cost engineering is an interdisciplinary field that focuses on the scientific approach towards management issues in engineering. It is still in a dynamic stage in that its domain is revised periodically. Despite the rapid expansion of its role in practice, it is found that cost engineering is not an academic discipline. In particular, it possesses most of the key attributes that an academic discipline should uphold, but it lacks attributes that are vital for an academic discipline: the expression of human imagination, and a generalized syntactical and conceptual structure. More work is therefore needed to establish cost engineering as an academic discipline. Apart from cultivating the vital attributes, partnerships between the cost engineering industry and academia can also be introduced. 相似文献

A number of internal and external pressures bear down on engineering colleges today. These include the shortage of experienced manpower, the rapid rate of scientific discoveries requiring absorption in curricula, the increasing college population, competition by industry for faculty members, and the need for additional income for plant expansion and faculty salaries. Within the body of engineering schools, one faction presses for the scientific reorientation of curricula while another holds to the professional art of design as the principle requirement in engineering colleges. Despite the traditional assumption that education is distinguished by large moments of inertia and that the time scale is measured in terms of generations, we lack sufficient time in a world of latent chaos. Positive and exciting internal forces must be injected into our dynamic system. 相似文献

A Reanalysis of Engineering Majors’ Self-Efficacy Beliefs 总被引：1，自引：1，他引：0
This study examines differences in women??s engineering self-efficacy beliefs across grade levels in comparison to men??s engineering self-efficacy (ESE) beliefs across grade levels. Data for this study was collected from 746 (635 men, 111 women) engineering students enrolled in a large research extensive university. Four major conclusions resulted from this study. (1) No significant differences in overall mean engineering self-efficacy scores were found by gender. However, this study found differences between men??s and women??s mean coping self-efficacy (CSE) and engineering career outcome expectations (ECOE) subscale scores. Freshmen men had significantly higher ECOE compared to upperclassmen women. (2) Overall, fifthyear men had significantly lower mean ESE scores compared to all other groups. (3) When the fifth-year group was removed from the data set, all first-year students had significantly lower subscale scores compared to all other years. In addition, men in their first-year of engineering had significantly lower subscale scores compared to other groups of men. (4) No significant differences in overall ESE scores were found among first to fifth-year women. Also, no significant differences in self-efficacy subscale scores were found among first to fifth-year women. 相似文献
