MathePraxis – connecting first-year mathematics with engineering applications

First-year engineering students often complain about their mathematics courses as the significance of the difficult and abstract calculus to their field of study remains unclear. We report on the project MathePraxis, a feasibility study which was designed as a means to give first-year students some impression about the use of mathematics in real practice. We aim to increase the motivation and retention rates among engineering students by connecting the contents of the first-year mathematics lectures with practical applications. We developed three projects, two of which are described in this article: an inverted pendulum considered as a model for the automated control within a Segway and a study on the optimal design of a ribbed cooler. In this article, we briefly present the mathematical content of the projects and report on their implementation.     

Teaching Engineering Practices

Engineering is featured prominently in the Next Generation Science Standards (NGSS) and related reform documents, but how its nature and methods are described is problematic. This paper is a systematic review and critique of that representation, and proposes that the disciplinary core ideas of engineering (as described in the NGSS) can be disregarded safely if the practices of engineering are better articulated and modeled through student engagement in engineering projects. A clearer distinction between science and engineering practices is outlined, and prior research is described that suggests that precollege engineering design can strengthen children’s understandings about scientific concepts. However, a piecemeal approach to teaching engineering practices is unlikely to result in students understanding engineering as a discipline. The implications for science teacher education are supplemented with lessons learned from a number of engineering education professional development projects.     

Creating a bridge to simulate simultaneous engineering experiences for senior undergraduate students

Launching new or improved products to the market typically involves extensive collaboration within and beyond the enterprise. Succeeding in a customer-driven market economy demands the practice of simultaneous engineering. The standard engineering or engineering technology curricula continue to make efforts in providing students with opportunities to engage in real-life projects that simulate simultaneous engineering. However, the educational community as a whole has much to implement in this area. This paper presents an approach used to nurture simultaneous engineering through a unique collaboration between instructors in different disciplines. Student teams, formed from three different classes, conceived problems and worked through a problem-solving model to design and develop solutions. An assessment of these interdisciplinary projects revealed significant learning outcomes and their relationships to the diversity of team members. The experiences of both students and instructors are described and some recommendations made for instructor teams that envisage interdisciplinary student projects.     

Characterizing engineering faculty's teaching approaches

In this paper, we identify several approaches engineering faculty use to teach engineering topics. We report results from an exploratory study, consisting of 16 faculty interviews from five diverse institutions of higher education. We focus specifically on engineering faculty because the engineering faculty teaching culture is not well explored, even though there are many ongoing projects to reform engineering education. The results from this study contribute to efforts currently underway to improve teaching and learning in engineering education, as well as in higher education. Results from this study highlight the disciplinary nature of teaching in the engineering domain. Furthermore, our results can serve as a foundation to compare teaching approaches in other disciplines, or to potential changes in engineering teaching practices.

Common elements of capstone projects in the world's top-ranked engineering universities

‘Capstone’ is a metaphor used to describe a final achievement that builds upon previous works and encapsulates them. Capstone projects are included in engineering curricula to integrate multi-disciplinary subjects and teach professional skills that are difficult to impart in a traditional lectured course. Since these projects serve to transition students into professional engineers, they have a direct impact on a university's industry reputation and ranking. Therefore, it is worthwhile to study the capstone programmes implemented at the world's top-ranked engineering universities to discover common elements which characterise them. In this paper, common elements of the capstone programmes implemented in mechanical and aerospace engineering undergraduate programmes in the world's top-ranked engineering universities are identified and analysed to determine established best practices. These practices can be modelled and applied to the pedagogy of engineering programmes at universities around the world to improve the development of professional skills of future graduates.     

The impact of group design projects in engineering on achievement goal orientations and academic outcomes

This study examined the impact of incorporating group design projects into a second-year engineering class on achievement goal orientations and two academic outcomes: concept inventory and final exam scores. In this study, two sections were taught using lecture format, but one section also completed three group design projects as part of their curriculum. The intervention of incorporating group design projects had a positive effect on mastery goals and a negative effect on performance-approach goals. The effect of the intervention on academic outcomes was mediated by mastery goals but not performance-approach or performance-avoidance goals. Implications and future directions are discussed.     

Projects in Technology Education and Fostering Learning: The Potential and Its Realization

The current study aimed at examining the efficacy of technological projects as learning tools by exploring the following questions: the extent to which projects in technology develop students as independent learners; the types of knowledge the students deal with in working on their projects; the role of problem-solving in technological projects; and how projects integrate into traditional schooling. The subjects were 53 high school (12th grade) students who prepared graduating projects in technology under the supervision of nine teachers. Data were collected by observing the students in the laboratory, administrating two questionnaires to both the students and the teachers, and analyzing 25 portfolios prepared by the students of their projects. The findings indicate that projects in technology provide a good opportunity to engage students in challenging tasks that enhance their learning skills. To maximize this potential, it is necessary to employ the project method from the early stages of learning technology. It is especially important that teachers having a strong engineering orientation also acquire pedagogical knowledge on issues such as fostering independent learning, creativity, peer learning and reflective practice in the technological classroom.     

Students' metacognition during an engineering design project

This study evaluated metacognitive changes of three groups of 160 engineering students working on 60 different design projects. Two metacognitive features, cognitive self‐appraisal and cognitive self‐management, were used to indicate students' metacognitive level. The Engineering Design Project Inventory was used to assess students' metacognition. Students were asked to complete the instrument at the early and final stages of the project. Statistical results revealed a significant change in mechanical engineering students' metacognition while engaged in the project. Eighteen themes of responses that described the influencing factors for the change in students' self‐appraisal and 23 themes of responses that described the influencing factors for their self‐management change were identified from two open‐ended questions.

After a brief survey of the engineering curriculum, the various computer facilities as well as the main software packages available, are highlighted. The presence of some important research centres, closely collaborating with the faculty considerably enhances the efforts of the university. The more general education CAE programs for students are described and also some specific CAD educational initiatives. A few typical research projects involving students collaboration as final thesis work are also reviewed.     

Assessment of Communication Competencies in Engineering Design Projects

Reforms in engineering education have caused a shift from the traditional stand-alone course in technical communication for Engineering students towards communication training integrated in courses and design projects that allows students to develop four layers of competence. This shift creates opportunities for realistic and situated learning, but offers challenges for assessment of communication competence at student, course and program levels. On the basis of a detailed definition of communicative competence, three formats for integrated communication training are described: Linked to design projects, integrated in design projects and integrated at program level. Assessment of communication competence in these formats is constrained by their characteristics with regard to student motivation, individual and group work, and situated learning.

Design Issues in a Cross‐institutional Collaboration on a Distance Education Course

Collaborative learning has been gaining momentum as a promising pedagogy in higher education. Research on student collaboration is increasing. However, one arena is often overlooked—faculty collaboration. In this article, a cross‐institutional faculty collaboration is presented. The context is faculty collaboration on the design of an undergraduate engineering course. Specifically, this paper examines design issues encountered in the faculty collaborations associated with developing, delivering, and redesigning a senior‐level engineering design course that was taught simultaneously at two universities. This course was taught in state‐of‐the‐art distance learning classrooms. Both within class and outside class, participating students and faculty made use of a Web‐based environment that supported a variety of synchronous and asynchronous interactions. The course itself focused on team design projects and provided instruction on the engineering design process, in various specific skills needed for the students’ projects, and on how to function effectively as part of a geographically distributed engineering design team. The participating faculty members represented different backgrounds, academic disciplines, and academic cultures. Issues related to collaborations on development, delivery, and redesign are elaborated. Based on the lessons learned, suggestions for future cross‐institutional faculty collaboration in course development are provided.

Final year engineering projects in Australia and Europe

The paper starts by emphasising that final year engineering projects are regarded important in the training and education of professional engineers in Australia and Europe. The sources of projects available to students were also mentioned. Some Australian universities insist on individual projects but some not, each with their own reasons. However, it can be argued that all European universities run individual projects. In most cases, whether it is in Australia or Europe, the total load for final year engineering projects is about 6.25% of the load of engineering programmes. Assessment methods were also described. They were all different whether in Australia or Europe but not very significant. It was discovered that literature reviews, oral presentations and written reports or dissertations were important elements in the assessment schemes. Many university staff, in both continents, encouraged students to publish their work in international conferences and journals if the originality of the projects was high. It can be argued that the individual project is most effective in learning outcome; however, the cost involved is also very high and its sustainability in smaller universities in Australia is in doubt.     

A comprehensive performance analysis and improvement method

Performance analysis and improvement are critical skills for the performance technologist. A comprehensive approach to these tasks, which includes techniques from industrial and organizational psychology, industrial engineering, and organizational behavior management, is described. The approach comprises four steps: (1) conducting an organization‐wide survey to identify general improvement areas, (2) objectively pinpointing performance improvement potentials, (3) systematically identifying performance constraints, and (4) selecting or designing an improvement technique. Survey results for 63 organizations are presented and the effect of management practices on management span of control are examined. Eighteen performance constraints are organized into a decision tree that is used to select 1 of 27 improvement techniques. The results of this approach to performance analysis and improvement are described for 58 improvement projects in a medium‐sized bank.

Assessing Institutionalization of Curricular and Pedagogical Reforms

Stakeholders often want evidence that curricular and pedagogical reforms will endure, but institutionalization of reforms is typically assessed superficially, if at all. This study involved developing and testing an Institutionalization Process Model. The model was developed from literature on institutional theory and a qualitative investigation of factors influencing institutionalization of externally funded curricular and pedagogical reforms at 7 engineering schools. The reforms focused on content (design), method (group projects), and improving the climate for students underrepresented in engineering. The model posits that regulative, normative, and cognitive institutionalization processes affect the likely diffusion of curricular and pedagogical reforms beyond faculty members directly involved in the reform effort. Subsequently, institutional data and a faculty survey conducted at the seven engineering schools were used to test the model using logistic regression. Findings showed that cognitive institutionalization indicators had a stronger influence than regulative or normative indicators on diffusion of design and group projects. The normative indicator of perceived support for teaching was the only significant predictor of increased sensitivity to the needs of underrepresented students.
