There is an increasing sensitivity to the challenges posed by the language of examination papers and of instruction in scientific subjects, especially for non-native speakers of English. It has been observed that in addition to technical subject-specific vocabulary, non-technical words such as instructional verbs have been sources of difficulty, and there are indications that other "ordinary" English words cause problems. For many years the aerospace industry has striven to make its manuals understandable and unambiguous to non-native speakers, a goal shared by writers of examination papers. To achieve this, the industry uses Simplified English, a controlled language with limited vocabulary and restricted grammatical rules. While recognising the limitations of this approach, the authors considered that by testing examination papers against the rules of Simplified English, it might be possible to identify areas of potential difficulty for non-native speakers. This paper describes the results of a study which tests past examination questions using software based on AECMA Simplified English, the controlled language in established use in the British aerospace industry. The results identified many lexical items which were not in the original list of "Approved words". Some of these were technical words and others were non-technical terms which are in common use in an engineering context. However, some were potential problem sources, including implicit instructions and vague or ambiguous words. Software alerts that related to sentence structure, in particular those related to sentence complexity, indicated that some sentences had additional problems. (Contains 1 note.)

Engineering, the "E" in STEM, is seldom taught as a distinct curriculum subject in English and Welsh schools to pupils under the age of 14 years. This contrasts with design and technology (D&T), taken in this paper to represent the largest contributor to the "T" in STEM (the remainder being taken to be the computing and digital communications aspects of ICT), which is currently taught to all pupils up to the age of 14 and remains a very popular option thereafter. The UK Government STEM programme (with sister projects: the LSIS 16+ STEM programme, the London Engineering Project and the 14-19 Diploma in Engineering) has provided large-scale action-research opportunities to better understand the nature of the T and E in STEM. This paper describes how the T and E in STEM have been found to be subjects in their own right and also to provide practical context for other STEM subjects. Some effective-practice guidelines have been established as a result, and these are discussed, but the paper concludes there is still much to do to fully establish the identity and character of the T and the E in STEM. Ideas for how this might develop are offered. (Contains 3 figures.)

From the mid-20th C., construction and engineering pedagogy and curricula have moved from long-held traditional experiential apprenticeship approaches to one ostensibly decoupling practice and theory. This paper traces this decoupling and explores modern-day opportunities and challenges for recoupling university education with industry practice. Within this context the UK Government funds Graduate Level Apprenticeships (GLA) and introduces the Teaching Excellence Framework (TEF), arguably signalling a desire to recouple. Nevertheless, many challenges from following previous UK Government policy prioritising research remain, particularly for post-1992 institutions. Arguably, Higher Education Institutions (HEI's) are at a pedagogical crossroads, considering whether to choose REF-ville, TEF-ville, and/or Apprentice Township. Do HEI's continue their increasingly decontextualized theoretical approach, or re-embrace construction and engineering education's experiential roots? We present and discuss opportunities and challenges currently facing HEI's, aiming to help inform decisions regarding recoupling theory and practice in construction and engineering teaching and learning, but potentially also other fields.

This paper presents an investigation of how experience-led content in an engineering degree can be strengthened by creating opportunities for engineering students to benefit from the knowledge, skills and resources of students with current professional experience. Students who study civil engineering part-time at Coventry University (while also working in the industry) are being used as mentors for full-time students, and careful attention is being paid to the input they can make to group project work. This paper reviews the results of evaluations of these two initiatives. The clearest enhancement to learning provided by the part-time students in these settings is the access they provide for the full-time students to real examples and the provision of actual physical artefacts such as drawings, photos, example documents and templates. Full-time students also gain an awareness of the value of the professional skills. The study confirms the value of these initiatives and points to future improvements. (Contains 3 tables.)

Despite sustained efforts to promote engineering careers to young women, it remains the most male-dominated academic discipline in Europe. This paper will provide an overview of UK data and research on women in engineering higher education, within the context of Europe. Comparisons between data from European countries representing various regions of Europe will highlight key differences and similarities between these nations in terms of women in engineering. Also, drawing on qualitative research the paper will explore UK students' experiences of gender, with a particular focus on the decision to study engineering and their experiences in higher education.

This paper draws attention to the findings of an exploratory study that critically identified and analysed relevant perceptions of elementary level engineering education within the UK. Utilising an approach based upon grounded theory methodology, 30 participants including teachers, representatives of government bodies and non-profit providers of primary level engineering initiatives were interviewed. Three main concepts were identified during the analysis of findings, each relevant to primary engineering education. These were pedagogic issues, exposure to engineering within the curriculum and children's interest. The paper concludes that the opportunity to make a real difference to children's education by stimulating their engineering imagination suggests this subject area is of particular value.

This paper describes the design, implementation, and evaluation of an educational program. Engineering the Future (EtF) sought to promote a permanent, informed awareness within the school community of high-level engineering by embedding key aspects of engineering within the education curriculum. The Scottish education system is used for a case study in which a range of pilot high schools worked in close partnership with two university engineering departments. The study focuses on electronic/electrical engineering (EEE), a technically challenging area, which reflects many of the problems that are intrinsic to modern society. In so doing, the work also sought to support and refine the transition from the school environment to higher education engineering courses. EtF is founded on research into transformational change and describes the findings of a three-year program that sought to develop sustainable and transferable means of encouraging school students to study engineering at university. The authors describe the conditions needed to support sustainable developments. They also provide an analysis of inevitable constraints and suggest strategies to address these issues. The paper concludes that sustainable long-term promotion of engineering within schools to support the transition to university is possible if certain conditions are fulfilled. These conditions include the use of a model that facilitates partnerships among researchers, policy-makers, and practitioners in all sectors. Building such essential linkages is often challenging, but this effort is necessary if changes in engineering education are to be realized and sustained. (Contains 1 table.)

Of all professions, engineering is ranked near the bottom in the UK in terms of the proportion of female applicants for university places, so the engineering industry is missing out on some of the best young talent available. Despite initiatives to increase the number of women entering engineering, there has been little change over the last decade. Engineering's popularity with males has declined over the same period. This paper discusses the findings of recent research into school students' perceptions of engineering. It identifies some of the barriers to engineering careers, including gender stereotyping, negative images and a lack of knowledge about the subject. The paper offers some solutions and concludes that schools, industry and higher education can work together to attract more young people of both sexes to engineering careers.

The attribute focus in engineering education now adopted by the engineering education accrediting bodies of the US, UK and Australia is based on meeting the assumed needs of professional practice. It is associated with an increasing expectation by employers of work-ready graduates rather than relying on subsequent work-based learning and experience to develop many of the essential professional practice attributes. Yet the scope of the mechanical engineering profession is broad and views of practitioners contributing to debate on attribute requirements are largely influenced by their own often unique professional formation. In addition, the formative development of the profession in Australia has been significantly influenced by 19th and 20th century UK and US practices, although historically the industrial profile of Australia has been strikingly different. An analysis of current industry distribution of Australian, UK and US mechanical engineers presented in this paper shows continuing, although less marked, differences. To develop a clearer perception of the profession in Australia, its educational formation, and operational environment, this paper provides a concise study of the formative development of the profession, and presents a breakdown of the industry sectors in which they are currently employed. The effects of momentous global changes in engineering employment and formation over recent decades are also discussed. Recent changes in engineering employment have included major structural changes to organisations, accelerating technical and educational developments and mounting societal expectations making it imperative that attributes be attuned to the new engineering paradigm as increasing demands are placed on our graduates. This paper provides an essential foundation for ongoing debate and analysis of attribute needs related to this broadly based engineering discipline. Although presented from an Australian perspective, many issues discussed are applicable worldwide. (Contains 2 tables.)

This paper describes the findings of the research done by Loughborough University in conjunction with ten construction industry collaborators in an attempt to identify what construction professionals mean by value. The aim of the research is to establish a common approach to identify value in projects and to monitor its development throughout the project life cycle so that it becomes part of everyday thinking and communication in multidisciplinary teams. The author links some of the findings to the formal value management methodology applied in the construction industry. The research draws on interviews with different professional disciplines to show that organizational and professional "values" impact on project value judgements. It further establishes a framework to identify and measure value. The author analyses this framework and examines alternative approaches to monitor value development as monitoring of value contributes to project success. The paper concludes that, to achieve a high-quality product, it is important to consider all stakeholder values on projects, not just those of the project sponsor. However, to achieve this, key construction players need to develop a refreshed approach to value management. To such an extent, teaching this research on university MSc engineering programmes helps to prompt alternative thinking to established methodologies. (Contains 2 tables and 3 figures.)

Emissions reductions targets for the UK set out in the Climate Change Act for the period to 2050 will only be achieved with significant changes to the built environment, which is currently estimated to account for 50% of the UK's carbon emissions. The socio-technological nature of Civil Engineering means that this field is uniquely placed to lead the UK through such adaptations. This paper discusses the importance of interdisciplinary teaching to produce multi-faceted team approaches to sustainable design solutions. Methods for measuring success in education are often not fit for purpose, producing good students but poor engineers. Real-world failures to apply sustainable design present a serious, difficult to detect, and ultimately economically negative situation. Techniques to replace summative examinations are presented and discussed, with the aim of enhancing core technical skills alongside those required for sustainable design. Finally, the role of our future engineers in policy-making is discussed. In addition to carbon, the provision of water and food will heavily influence the work of civil engineers in the coming decades. Leadership from civil engineers with the technical knowledge and social awareness to tackle these issues will be required. This provides both opportunities and challenges for engineering education in the UK.

This paper reports on a funded collaborative large-scale curriculum innovation and enhancement project undertaken as part of a UK National Higher Education Science, Technology Engineering and Mathematics (STEM) programme. Its aim was to develop undergraduate curricula to teach appropriate skills for professional engineering practice more effectively. Sheffield Hallam University (SHU) led the project with Loughborough and London South Bank Universities as partners. Project advisers included Imperial College London and Coventry University. The four collaborative project objectives were to: develop an approach to interdisciplinary cross-year integration and professional team practice, project management, learning, teaching and assessment; develop cross-year student support systems to aid the above; develop the assessment of professional skills; and evaluate and disseminate the project outcomes to the wider STEM community. The activity allowed partners to trial and test a rounded implementation in each institution involving academic taught material, practical laboratory-based project work, together with an appropriate support structure for operation across a range of undergraduate courses.

Engineering academic units might engage with social media for a range of purposes including for general communication with students, staff, alumni, other important stakeholders and the wider community at large; for student recruitment and for marketing and promotion more generally. This paper presents an investigation into the use of Twitter by six engineering academic units internationally, using publicly available Twitter data over an 18-month period for analysis and visualization, to characterize the engagement by engineering academic units with one popular social media tool. Widely varying levels of activity were observed, from essentially undirected "Megaphone" Tweeting, through to sustained and complex interactions with multiple external accounts. This work provides insights into how engineering academic units are using Twitter and how they might more effectively use the platform to achieve their individual objectives for institutional social media communications and marketing, and offers a methodology for future research.

There is increasing evidence that action learning is valuable in a higher education setting. This paper goes on to report a personal development programme, based on principles of critical action learning, where the aim is to equip early-career scientists and engineers working in a university setting with the knowledge, skills and confidence to approach the management of innovation. After learning about action learning and critical reflection, the participants, all postdoctorate researchers, completed innovation projects at work, meeting in action learning sets as they proceed. We explain a method of critical thinking before reporting results from an evaluation study based on interviews and focus groups. We consider examples of projects undertaken before considering challenges for students with this approach to learning. Challenges included scepticism about the usefulness of management literature, difficulties in finding "problems" within the constraints of postdoctoral work, and the discomfort and intensiveness of action learning. However, through adaptation by the tutors with students, some significant results were achieved.

UK educators often express concerns that students from some cultural backgrounds frequently seem unwilling or are unable to apply critical thinking skills within their academic programmes. This may be due not to a lack of ability or confidence but rather to the way they have been previously taught and assessed. Often, the design of UK courses implicitly requires critical thinking skills, but the design of the use of these skills in courses may not have taken into account the conceptualization of critical thinking across a diverse global group of students. This paper reports on the results of a study of Master's engineering students from two universities in the UK to assess their conceptualization of critical thinking. The findings provide evidence that international engineering students' understanding of critical thinking is not well developed, although they may, without being aware of it, have a critical thinking mindset, and often display these skills.

In the UK, women remain under-represented in engineering and technology (E&T). Research has, therefore, investigated barriers and solutions to women's recruitment, retention and progression. Recruitment into the sector may be supported by exploring the career decisions of women and men who have chosen to study E&T. Triangulating quantitative and qualitative data from E&T students at a UK university, this paper examines the gendered nature of career choice narratives. It finds that women often maintain contradictory views; upholding gendered stereotypes about women's suitability for the so-called masculine work, yet also subscribing to ideals that the sector is accessible to all who wish to work in it. This is explained using an individualist framework in which women construct an autonomous sense of self, yet are also shaped by a gendered self. Women's discourse around career choice, therefore, reveals the problematic nature of gender norms for achieving gender equity in E&T. (Contains 2 tables and 3 notes.)

Recent scholarship references indicate that integration of the student body can result in an enhanced learning experience for students and also greater satisfaction. This paper reports the results of a case study whereby mechanical engineering students studying at a newly established branch campus in Dubai of a British university were exposed to vertical and horizontal integration. Different activities have been embedded to ensure that students integrated and worked together with their peers and colleagues at different levels. The implemented processes and practices led to improved academic achievements, which were better than those of a similar cohort of students where no effort had been made to integrate. The analysis revealed that cooperative learning and the degree of academic support provided by teachers are positively and directly correlated with academic as well as the students' own sense of personal achievement. The results are discussed in light of previous research and with reference to the cultural context of the study. (Contains 10 figures and 3 tables.)

This paper reports on a multifaceted approach in electrical engineering outreach focused on the area of semiconductor technology. The activities developed can be used in combination for a very wide range of audiences in both age and stage of education, as has been demonstrated with great success. Moreover, the project has developed cross-disciplinary activities designed to engage nonscientific audiences and has used entirely "nonscientific" venues, such as art galleries. The suite of activities, given the umbrella title "Chips for Everyone", includes: (1) "Chips for Everyone": drop-in activities for fairs, shows, shopping centers; (2) "Chips with Relish": interactive workshops for groups of school pupils; and (3) "Chips with Flair": an arts-science collaboration in music, art, video, and engineering to present a new perspective on semiconductor technology. To achieve this diverse mix of outreach activities, the Chips for Everyone team represents a very broad spectrum of skills, its members being engineering academics, musicians, artists, education academics, public engagement specialists, and student teachers in technology. The development process is quite generic and could be applied in other science, technology, engineering, and mathematics (STEM) areas. The subject focus of the project is semiconductor technology, a technology that influences the daily lives of everyone and yet is largely invisible. The activities seek to engage, engender interest, and promote informed discussion about this technology and engineering in general. From modest beginnings as a filler during the setting up of another outreach program, Chips for Everyone has developed into a major program reaching over 25 000 young people and families in school workshops, shopping centers, and art exhibitions in Scotland and across the U.K. The development method for the activities is innovative and creative, using the complimentary skills of research academics and students in both electronic engineering and technology initial-teacher education (ITE).

The nuclear engineer emerged as a new form of recognised technical professional between 1940 and the early 1960s as nuclear fission, the chain reaction and their applications were explored. The institutionalization of nuclear engineering--channelled into new national laboratories and corporate design offices during the decade after the war, and hurried into academic venues thereafter--proved unusually dependent on government definition and support. This paper contrasts the distinct histories of the new discipline in the USA and UK (and, more briefly, Canada). In the segregated and influential environments of institutional laboratories and factories, historical actors such as physicist Walter Zinn in the USA and industrial chemist Christopher Hinton in the UK proved influential in shaping the roles and perceptions of nuclear specialists. More broadly, I argue that the State-managed implantation of the new subject within further and higher education curricula was shaped strongly by distinct political and economic contexts in which secrecy, postwar prestige and differing industrial cultures were decisive factors.

High skills are today seen as being of vital importance to economies, industries, companies and individuals. The engineering industry is no exception and the graduate engineer has a key position in this regard. In the research reported in this paper, the authors use in-depth interviews with industry experts to investigate the provision of undergraduate engineering education in the UK. The current and future skill needs of industry are examined. A typology of future engineering roles and their requisite attributes is proposed. Implications for undergraduate engineering are also discussed. (Contains 1 figure and 1 table.)

Courses in product design are offered within the United Kingdom at the University of Brighton and the University of Sussex and in both cases are run within engineering departments alongside traditional engineering courses. This paper outlines some of the intrinsic pedagogic practices that are employed by these, and other, design courses. It highlights why creativity is a central tenet within these courses, which has underpinned the successful bid by the universities to jointly become the UK Centre of Excellence in Teaching and Learning in Creativity (CETL in C), and why, in particular, creativity is a key requirement in sustainable design. It supposes why these practices might, and should, offer a suitable role model for more traditional engineering courses. (Contains 1 table.)

This paper gives a synopsis of an extensive programme of case studies on real uses of computer-assisted learning (CAL) materials within UK engineering degree programmes. The programme was conducted between 2000 and 2003 and followed a questionnaire-based survey looking at CAL use in the UK and in Australia. The synopsis reveals a number of key messages for academic tutors and authors including students' enthusiasm for notes, self-tests and features to aid visualisation. Publishers should also consider pricing and licensing arrangements suited to the individual user. (Contains 5 tables.)

The role and performance of the engineering and scientific institutions in the UK have been undergoing gradual change in response to external, State and global influences. Consequently, the institutions are having to adapt and in the process of doing so the traditional balance between learned society and qualifying association activities is now in a state of flux. The relevance of professional registration is being questioned by employers and practitioners alike and the institutions are now having to operate in a greater collaborative context than hitherto. This paper reviews developments which have been taking place since the early 1970's and, by using responses from a survey of engineering and scientific institutions, identifies significant current problems and some challenges which lie ahead and which have yet to be confronted if the institutions are to continue to make a constructive contribution to society.

This paper reports a survey of the progress of participants in a year in industry scheme for A' level graduates in the UK typically aged 18/19. The scheme involves spending a supervised year in industry prior to a degree programme in engineering. The evidence shows that the year in industry: has a beneficial effect on the degree classification of the academically weaker participants, but little effect on the stronger; encourages all participants to take up further study; provides participants with a more positive picture of industry and engineering; but does not provide greater motivation to enter industry; provides greater financial remuneration in the world of work than would otherwise be the case. These results can be interpreted in terms of the way young people weigh the benefits of different career paths. Our hypothesis is that this involves moving to situations where they are more likely to be treated as adults. (Contains 7 tables and 2 charts.)

At present, value management (VM) is struggling to survive amidst other management fads. The problem is that it is still not recognized as a professional or academic discipline. There is no sound academic base and a lack of understanding by the public, owners and corporate organizations. The future survival of VM is therefore always being questioned. This study adopts a quantitative approach, trying to gaze through a "crystal ball" to look at current practices and forecast the future courses and directions of VM by considering different aspects such as education, research, practice, VM societies and promotional activities. Various influences on VM development are also examined. The survey sample was taken from the membership directories of SAVE International, USA, and the Institute of Value Management, UK. Forty per cent of the members were selected for the study on a random basis, and the response rate was 23%. From the survey findings, each of the different aspects will be examined in detail. In addition, the paper introduces a building engineering and management programme on offer in Hong Kong, which integrates the VM topic into the syllabus of a course in engineering economics.

The programmes offered by both institutions are geared to the application of current technology. All the University of Derby programmes, including the BSc(Hons) degree in Electrical and Electronic Engineering and the Higher Technical Institute Diploma in Electrical Engineering, are accredited in the UK at Incorporated Engineer level by the Institution of Incorporated Engineers. Both academic institutions have adopted outcomes-based assessment and this paper examines how this influences the assessment of student learning, and considers the experience gained from quite different approaches used to deliver a similar learning experience.

Engineering Design is rightfully regarded as a key element within all university Engineering courses and most laboratory assignments and project work seek to optimise the student's acquisition of knowledge and understanding of this process. Within this paper Engineering Design has been classified into a new "hierarchy of task level" each one defined by an increased degree of design freedom that an Engineer has to consider. It is argued that this classification accurately reflects the varying complexity of tasks found within real world industrial environment. The optimal matching of these task levels to university course assignments is discussed and limitations identified. The need for further design experience within a wider industrial context is shown to be essential if the nature of design freedom is to be fully appreciated by the next generation of professional Engineers.

This paper examines the notion of clusters and clustering from the perspective of complex capital projects, drawing on two detailed case studies of long-term engineering projects. It suggests that conventional notions of clusters are often predicated on a high volume model of production and a stable environment for innovation. The case studies illustrate how the locus of innovation is shifting in response to changes in the nature of demand for major capital goods and the services associated with them. It is suggested this leads to greater dispersion in networks for innovation within complex capital projects. [ABSTRACT FROM AUTHOR]

The concerns over shortages of engineering graduates with the right skills entering industry is increasing. Lack of highly skilled graduates increases recruitment costs and affects the performance of the UK industry. Employers should therefore supply more feedback on the quality of graduates to make sure the changing requirements of industry are recognized and reflected in engineering degree programs. This research investigated how linking students throughout their degree study with employers affected students, academia, and employers. Evidence was obtained from sponsored and placement undergraduate engineering students in a department of Civil and Building Engineering, their academic tutors, and their employers. The results showed sponsored engineering programs that are operated by a university department in cooperation with employers matched the needs of students and requirements of employers. Sponsorship allowed both students and sponsors to have practical experience of working arrangements over three or more years before either party made a full commitment, it helped to develop undergraduate programs, and provided students with experience of real-life industrial engineering challenges. The main conclusions to be drawn from this study are sponsorship is a valuable strategy for enhancing the professional skills of intending engineers. More feedback from employers on the quality of graduates should be provided to departments of engineering so that the changing requirements of industry are recognized and reflected in engineering degree programs.

A great deal of enterprise teaching is carried out in business schools and has been for many years. The challenge of the UK's Science Enterprise Challenge was to extend enterprise teaching more thoroughly to science and engineering students. While some of the centres launched under the initiative developed the activity of business schools, there were notable exceptions. This paper focuses on the attempts to implement the challenges of teaching enterprise to engineering students in the Department of Mechanical Engineering at the University of Sheffield. This was one of the most successful departmental interventions of the White Rose Centre for Enterprise (WRCE), formed in 1999 as part of the UK Science Enterprise Challenge initiative. WRCE's remit, like that of the other science enterprise centres, was to increase enterprise learning and entrepreneurship, thus bringing about a 'cultural change' in those universities involved in the collaboration. WRCE's approach was to embed enterprise in the teaching programme of the science and engineering departments. The general propositions of WRCE are reviewed in the light of the activities within the Department of Mechanical Engineering. Some detailed qualifications of those propositions arise, with strong emphasis on the importance of pedagogic approaches and sequence of content. [ABSTRACT FROM AUTHOR]
