Tornado Damage Assessment in the aftermath of the May 20th 2013 Moore Oklahoma Tornado

This report presents observations, findings, and recommendations from an engineering reconnaissance trip following the May 20th, 2013 tornado that struck Moore, Oklahoma. A team of faculty, research scientists, professional engineers, and civil engineering students were tasked with investigating and documenting the performance of critical facility buildings and residences, (IBC Occupancy Category II, III, and IV), in Moore, OK. The Enhanced Fujita (EF) 5 tornado created a 17-mile long damage swath destroying over 12,000 buildings and killing 24 people. The total economic loss from this single event was estimated at $3 billion. The May 20th tornado was the third major tornado to hit Moore in the previous 15 years.

Laboratories transformation

BACKGROUND OR CONTEXT Laboratories provide the physical spaces for engineering students to connect with theory and have a personal hands-on learning experience. Learning space design and development is well established in many universities however laboratories are often not part of that movement. While active, collaborative and group learning pedagogies are all key words in relation to these new spaces the concepts have always been central to laboratory based learning. The opportunity to build on and strengthen good practice in laboratories is immense. In the 2001 review “Universities in Crisis” many references are made to the decline of laboratories. One such comment in the review was made by Professor Ian Chubb (AVCC), who in 2013, as Chief Scientist for Australia, identifies the national concern about STEM education and presents a strategic plan to address the challenges ahead. What has been achieved and changed in engineering teaching and research laboratories in this time? PURPOSE OR GOAL A large number of universities in Australia and New Zealand own laboratory and other infrastructure designed well for the era they were built but now showing signs of their age, unable to meet the needs of today’s students, limiting the effectiveness of learning outcomes and presenting very low utilisation rates. This paper will present a model for new learning space design that improves student experience and engagement, supporting academic aims and significantly raising the space utilisation rate. APPROACH A new approach in laboratory teaching and research including new management has been adopted by the engineering disciplines at QUT. Flexibility is an underpinning principle along with the modularisation of fixed teaching and learning equipment, high utilisation of spaces and dynamic pedagogical approaches. The revitalised laboratories and workshop facilities are used primarily for the engineering disciplines and increasingly for integrated use across many disciplines in the STEM context. The new approach was built upon a base of an integrated faculty structure from 2005 and realised in 2010 as an associated development with the new Science and Engineering Centre (SEC). Evaluation through student feedback surveys for practical activities, utilisation rate statistics and uptake by academic and technical staff indicate a very positive outcome. DISCUSSION Resulting from this implementation has been increased satisfaction by students, creation of social learning and connecting space and an environment that meets the needs and challenges of active, collaborative and group learning pedagogies. Academic staff are supported, technical operations are efficient and laboratories are effectively utilised. RECOMMENDATIONS/IMPLICATIONS/CONCLUSION Future opportunities for continuous improvement are evident in using the student feedback to rectify faults and improve equipment, environment and process. The model is easily articulated and visible to other interested parties to contribute to sector wide development of learning spaces.

New approaches to materials education

A novel approach to the teaching of material to engineering students is outlined. It starts from the overview of the "world" of materials made possible by material property charts, and develops both an understanding of material properties and skills in selecting materials and processes to meet design specifications. It is supported by extensive computerbased methods and tools, and is well adapted both for elementary and for advanced courses. © 2003 by Granta Design Limited.

工科大学生心理应激、应对与自我概念的关系研究

In the period of college, an individual matures rapidly in all aspects. College engineering students are the important parts of undergraduates. The state of an individual’s mental health may affect and even decide his future life and work. The level of the student’s self-concept and the kind of coping styles the students adopt are directly related to their mental health. So, it is significant to study the psychological stress, coping and self-concept of college engineering students for the mental health education and research of college engineering students. Based on overviews of former research, with the China College Student Psychological Stress Scale, the Coping Styles Scale and the Tennessee Self-Concept Scale, 559 college engineering students were investigated to explore the characteristics of and the relationship between the psychological stress, coping styles and self-concept of college engineering students. The results showed: 1. The stresses of learning, living and daily hassles were the main psychological stresses of college engineering students. There were significant differences in psychological stress between students from the countryside and those from urban areas, between needy students and non-needy students, between single-parent students and non-single-parent students, among students from different grades, with different academic achievements and of different postgraduate targets, between student party members and non-party members, between student cadres and non-cadres. However, there were no significant differences between male and female, between those from single-child families and from multiple-child families. 2. The coping styles of solving problem, seeking help and rationalization were the main coping styles of college engineering students. There were significant differences in the coping styles between needy students and non-needy students, among students from different grades, with different academic achievements and of different postgraduate targets, between student party members and non-party members, between student cadres and non-cadres. However, there were no significant differences between students from the countryside and from urban areas, between male and female, between single-parent students and non-single-parent students, between those from single-child families and from multiple-child families. 3. The self-concept of college engineering students was positive in general. There were significant differences in self-concept between students from the countryside and those from urban areas, between male and female, between needy students and non-needy students, between single-parent students and non-single-parent students, among students from different grades, with different academic achievements and of different postgraduate targets, between student party members and non-party members, between student cadres and non-cadres. However, there were no significant differences between those from single-child families and from multiple-child families. 4. The psychological stress had significantly negative correlation to the immature coping styles, and had partial correlation to the mature coping styles. Coping style has significant predictability on psychological stress. 5. The positive factors of the self-concept had significantly negative correlation to psychological stress, but self-criticism had positive correlation to psychological stress. There are significant differences between high self-concept students and low self-concept students for psychological stress. Self-concept has significant predictability on psychological stress. 6. The positive factors of the self-concept had significantly negative correlation to the coping styles of self-blame, illusion, avoidance, and rationalization, but had significantly positive correlation to the coping style of solving problem and seeking help. Self-criticism had significantly negative correlation to the coping styles of self-blame, illusion, avoidance, and rationalization. There are significant differences between high self-concept students and low self-concept students for coping styles. Self-concept has significant predictability on coping styles. 7. The self-concept of college engineering students had an effect on psychological stress by coping styles. However, the effect by the immature coping styles was higher than that to the mental health directly, and the effect by the mature and mixed coping styles was slighter than that to the mental health directly. According to the results, improving the college engineering students’ self-concept level and establishing right self-concept, developing the middle school student’ active coping styles and overcoming the negative coping styles are essential and important to the college engineering students’ mental health and provide useful clues for the psychological education of the college engineering students.

Group Design-Build-Test Projects as the Core of an Integrated Curriculum in Product Design and Development

The School of Mechanical and Aerospace Engineering at Queen’s University Belfast introduced a new degree programme in Product Design and Development (PDD) in 2004. As well as setting out to meet all UK-SPEC requirements, the entirely new curriculum was developed in line with the syllabus and standards defined by the CDIO Initiative, an international collaboration of universities aiming to improve the education of engineering students. The CDIO ethos is that students are taught in the context of conceiving, designing, implementing and operating a product or system. Fundamental to this is an integrated curriculum with multiple Design-Build-Test (DBT) experiences at the core. Unlike most traditional engineering courses the PDD degree features group DBT projects in all years of the programme. The projects increase in complexity and challenge in a staged manner, with learning outcomes guided by Bloom’s taxonomy of learning domains. The integrated course structure enables the immediate application of disciplinary knowledge, gained from other modules, as well as development of professional skills and attributes in the context of the DBT activity. This has a positive impact on student engagement and the embedding of these relevant skills, identified from a stakeholder survey, has also been shown to better prepare students for professional practice. This paper will detail the methodology used in the development of the curriculum, refinements that have been made during the first five years of operation and discuss the resource and staffing issues raised in facilitating such a learning environment.

Does flexibility in secondary level mathematics curriculum affect degree performance?

The authors have much experience in developing mathematics skills of first-year engineering students and attempting to ensure a smooth transition from secondary school to university. Concerns exist due to there being flexibility in the choice of modules needed to obtain a secondary level (A-level) mathematics qualification. This qualification is based on some core (pure maths) modules and a selection from mechanics and statistics modules. A survey of aerospace and mechanical engineering students in Queen’s University Belfast revealed that a combination of both mechanics and statistics (the basic module in both) was by far the most popular choice and therefore only about one quarter of this cohort had studied mechanics beyond the basic module within school maths. Those students who studied the extra mechanics and who achieved top grades at school subsequently did better in two core, first-year engineering courses. However, students with a lower grade from school did not seem to gain any significant advantage in the first-year engineering courses despite having the extra mechanics background. This investigation ties in with ongoing and wider concerns with secondary level mathematics provision in the UK.

Interpreting A-level Mathematics grades – as easy as A, B, C?

Many concerns have been expressed that students’ basic mathematical skills have deteriorated during the 1990s and there has been disquiet that current A-level grading does not distinguish adequately between the more able students. This study reports the author’s experiences of teaching maths to large classes of first-year engineering students and aims to enhance understanding of levels of mathematical competence in more recent years. Over the last four years, the classes have consisted of a very large proportion of highly qualified students – about 91% of them had at least grade B in A-level Mathematics. With a small group of students having followed a non-traditional route to university (no A-level maths) and another group having benefitted through taking A-level Further Mathematics at school, the classes have contained a very wide range of mathematical backgrounds. Despite the introductory maths course at university involving mainly repetition of A-level material, students’ marks were spread over a very wide range – for example, A-level Mathematics grade B students have scored across the range 16 – 97%. Analytical integration is the topic which produced the largest variation in performance across the class but, in contrast, the A-level students generally performed well in differentiation. Initial analysis suggests some stability in recent years in the mathematical proficiency of students with a particular A-level Mathematics grade. Allowing choice of applied maths modules as part of the A-level maths qualification increases the variety of students’ mathematical backgrounds and their selection from mechanics, statistics or decision maths is not clear from the final qualification.

Time Efficient Assessment and Feedback Methods for Large Computer-Aided-Design Cohorts

Timely and individualized feedback on coursework is desirable from a student perspective as it facilitates formative development and encourages reflective learning practice. Faculty however are faced with a significant and potentially time consuming challenge when teaching larger cohorts if they are to provide feedback which is timely, individualized and detailed. Additionally, for subjects which assess non-traditional submissions, such as Computer-Aided-Design (CAD), the methods for assessment and feedback tend not to be so well developed or optimized. Issues can also arise over the consistency of the feedback provided. Evaluations of Computer-Assisted feedback in other disciplines (Denton et al, 2008), (Croft et al, 2001) have shown students prefer this method of feedback to traditional “red pen” marking and also that such methods can be more time efficient for faculty.
Herein, approaches are described which make use of technology and additional software tools to speed up, simplify and automate assessment and the provision of feedback for large cohorts of first and second year engineering students studying modules where CAD files are submitted electronically. A range of automated methods are described and compared with more “manual” approaches. Specifically one method uses an application programming interface (API) to interrogate SolidWorks models and extract information into an Excel spreadsheet, which is then used to automatically send feedback emails. Another method describes the use of audio recordings made during model interrogation which reduces the amount of time while increasing the level of detail provided as feedback.
Limitations found with these methods and problems encountered are discussed along with a quantified assessment of time saving efficiencies made.

A Transition Study to Support Curriculum Reform

This paper presents details of a project to support the transition from school to university for engineering students in the UK. The initial phases have already been disseminated by the project collaborators. The background, rationale, objectives and outcomes of this latter phase of the project are presented and specific data from a web-based transition diagnostic is discussed which verifies specific learning issues amongst engineering students enrolling in their first year of study. This prompted further investigations into these specific learning issues, which produced relevant data pertinent to enhancing learning through curriculum reform with the ultimate goal of accommodating the transition from school to university, improving the learning experience and increasing retention.

Saúde mental e comportamentos de risco em estudantes universitários

A saúde dos estudantes do ensino superior é uma importante questão de saúde pública, com impacto não só a nível pessoal e social, como também institucional. Nesse sentido, a presente investigação teve como objectivos: 1) caracterizar a saúde mental dos estudantes universitários, ao nível de sintomas depressivos, stress e bem-estar; 2) identificar os seus padrões de consumo de álcool, em termos de quantidade e frequência de consumo, ingestão esporádica excessiva e tipos de bebidas mais ingeridas; 3) conhecer a prevalência de dois comportamentos de risco ligados ao álcool, os comportamentos sexuais de risco e a condução sob o efeito de álcool; 4) analisar a relação entre saúde mental e consumo de álcool no ensino superior. Para esse efeito, realizou-se um estudo transversal com 666 alunos do 1º ciclo da Universidade de Aveiro. Os instrumentos utilizados foram: Ficha de Caracterização Sociodemográfica e Académica; Medida de Saúde Comportamental-20; Inventário da Depressão em Estudantes Universitários; Inventário de Stress em Estudantes Universitários; Questionário de Comportamentos de Risco em Estudantes Universitários. Os resultados mostraram que 32% dos estudantes se encontravam num patamar disfuncional quanto à sua saúde mental, 15% apresentavam sintomatologia depressiva e 26% sofriam de níveis elevados de stress, mas que apenas uma minoria destes alunos estava a receber apoio psicológico profissional. Os níveis de saúde mental foram inferiores nas mulheres, nos alunos do 1º e do 3º ano, da área de Saúde e de estatuto socioeconómico baixo. Para além disso, a maioria dos estudantes consumia álcool e 41% tiveram episódios de ingestão excessiva no último mês. Durante as festas académicas, um quarto dos estudantes ingeriu cinco ou mais bebidas por noite. O consumo de álcool foi superior nos homens, nos estudantes da área de Engenharias, de estatuto socioeconómico elevado e nos deslocados. Quanto a problemas ligados ao álcool, 13% dos estudantes sexualmente activos admitiram ter tido relações sexuais decorrentes do consumo de álcool, no último ano, e 29% praticaram condução sob o efeito de álcool no último mês. Estes comportamentos foram mais frequentes em estudantes do sexo masculino e naqueles que tiveram episódios de ingestão excessiva. Não se encontrou, de um modo geral, uma relação entre saúde mental e consumo de álcool, tendo sido detectadas apenas correlações, fracas, do stress e do bem-estar com o consumo de álcool. Ao contrário do que era esperado, verificou-se que à medida que o consumo de álcool aumentava, o stress diminuía e o bem-estar aumentava ligeiramente. Estes dados salientam a necessidade de as instituições do ensino superior reforçarem a identificação e o tratamento de problemas existentes e apostarem na prevenção, tanto através de estratégias dirigidas a toda a comunidade, no âmbito da educação para a saúde e da literacia em saúde mental, como através de iniciativas destinadas aos grupos de risco aqui identificados.

Construção de competências transversais no sector das telecomunicações : percepções e estilos de aprendizagem

Tem sido frequentemente referido na literatura que os diplomados do ensino superior estão mal preparados para as exigências do mercado de trabalho. Face à situação económica actual, mais do que conhecimentos académicos, os estudantes necessitam desenvolver competências que promovam a sua empregabilidade e aprendizagem ao longo da vida. Isto é particularmente relevante no sector das Telecomunicações, face às constantes mutações tecnológicas e organizacionais. Estas competências são usualmente designadas por competências transversais, englobam o conjunto de competências que são comuns às diferentes actividades profissionais. Trata-se de competências imprescindíveis à empregabilidade, uma vez que permitem aos indivíduos agir numa multiplicidade de tarefas e funções. O presente trabalho propõe uma caracterização da construção das competências transversais no sector das Telecomunicações, tendo por base as percepções dos estudantes de engenharia, mas também as percepções das empresas do sector. No sentido de apoiar a fundamentação de estratégias práticas promotoras do desenvolvimento das competências transversais, o presente trabalho analisou os estilos de aprendizagem dos alunos de engenharia, tendo sido realizado um estudo para a adaptação do Index of Learning Styles (Felder & Soloman, n.d.) para a população portuguesa. No presente trabalho, 337 estudantes avaliaram o seu domínio num conjunto de competências transversais, bem como a sua importância para um futuro profissional. Desta avaliação foram identificados gaps de competências transversais que traduzem necessidades de desenvolvimento e formação. Foram também analisadas as relações entre as competências transversais e os estilos de aprendizagem dos estudantes, e as relações entre as competências transversais e um conjunto de variáveis psicológicas relacionadas com o desempenho competente: auto-eficácia, auto-regulação e optimismo. Representantes de empresas do sector das Telecomunicações avaliaram a importância das mesmas competências transversais para as práticas de negócio. A interpretação dos resultados, bem como as possíveis implicações destes no desenvolvimento de estratégias promotoras da construção das competências transversais, são discutidos à luz da literatura relevante.

Qualidade, sustentabilidade e FCS: o caso de uma IES privada no Brasil

Este trabalho de investigação foi realizado com o objetivo geral de se descobrir quais são os Fatores Críticos de Sucesso e os aspectos chaves de qualidade e sustentabilidade, a serem considerados no ensino de Engenharia de Produção em um IES privada no Brasil. No presente estudo de caso executou-se uma revisão teórica sistemática nas áreas temáticas da pesquisa, que propiciou a criação de um framework que define os 7 Fatores Críticos de Sucesso ao ensino de Engenharia de Produção, apontando sua divisão nas áreas de qualidade e sustentabilidade, e, por fim, a subdivisão em 6 subáreas de ações operacionais a serem consideradas pela gestão de IES para alcançar melhorias de desempenho em suas atividades. Posteriormente ao levantamento teórico, foi realizado o estudo de caso propriamente dito, que dividiu-se em duas etapas, uma qualitativa e uma quantitativa. Na primeira elaborou-se um roteiro de entrevista em profundidade aplicada a um terço do corpo docente do curso em estudo, captando a impressão destes sobre as temáticas em estudo voltadas à execução de suas atividades. Os dados obtidos foram organizados com o auxílio do software WebQDA, gerando ideias do que deve ser trabalhado para melhorar as condições e resultados do referido curso. A etapa quantitativa foi iniciada com a elaboração de um questionário on-line, desenvolvido a partir do enquadramento teórico e da informação obtida na parte qualitativa do estudo, que envolveu respostas de cerca de dois terços dos discentes de Engenharia de Produção. A informação foi recolhida através de um formulário disponibilizado pelo googledocs, e os resultados foram analisados com o auxílio do software SPSS, permitindo conhecer as expectativas e percepções dos alunos e, consequentemente, os gaps provenientes a serem trabalhados. Finalmente, o estudo revelou que para aspectos de qualidade, os pontos de tangibilidade, como infraestrutura geral, laboratórios técnicos específicos, cantina e biblioteca, precisam ser melhorados, e, para aspectos de sustentabilidade, surge a necessidade de melhorar as formas de divulgação do curso, captação de alunos e propostas para a retenção dos mesmos para outros cursos e projetos da IES. Deste modo, o trabalho desenvolvido atingiu seu objetivo e se mostrou válido para aplicações na IES e em outros cursos da mesma (com as devidas adaptações). Fica como recomendação final aplicar o estudo periodicamente para se captar as mudanças situacionais que ocorrerem, manter um controle eficiente dos aspectos estudados e gerar melhorias contínuas no curso estudado e na própria IES.

Smart object for 3D interaction

This paper reports on the creation of an interface for 3D virtual environments, computer-aided design applications or computer games. Standard computer interfaces are bound to 2D surfaces, e.g., computer mouses, keyboards, touch pads or touch screens. The Smart Object is intended to provide the user with a 3D interface by using sensors that register movement (inertial measurement unit), touch (touch screen) and voice (microphone). The design and development process as well as the tests and results are presented in this paper. The Smart Object was developed by a team of four third-year engineering students from diverse scientific backgrounds and nationalities during one semester.

The European Project Semester at ISEP: the challenge of educating global engineers

Current engineering education challenges require approaches that promote scientific, technical, design and complementary skills while fostering autonomy, innovation and responsibility. The European Project Semester (EPS) at Instituto Superior de Engenharia do Porto (ISEP) (EPS@ISEP) is a one semester project-based learning programme (30 European Credit Transfer Units (ECTU)) for engineering students from diverse scientific backgrounds and nationalities that intends to address these goals. The students, organised in multidisciplinary and multicultural teams, are challenged to solve real multidisciplinary problems during one semester. The EPS package, although on project development (20 ECTU), includes a series of complementary seminars aimed at fostering soft, project-related and engineering transversal skills (10 ECTU). Hence, the students enrolled in this programme improve their transversal skills and learn, together and with the team of supervisors, subjects distinct from their core training. This paper presents the structure, implementation and results of the EPS@ISEP that was created in 2011 to apply the best engineering practices and promote internationalisation and engineering education innovation at ISEP.

Standard commercial education robotic platform: intermediate solution to teaching robotics

Teaching robotics to students at the beginning of their studies has become a huge challenge. Simulation environments can be an effective solution to that challenge where students can interact with simulated robots and have the first contact with robotic constraints. From our previous experience with simulation environments it was possible to observe that students with lower background knowledge in robotics where able to deal with a limited number of constraints, implement a simulated robotic platform and study several sensors. The question is: after this first phase what should be the best approach? Should the student start developing their own hardware? Hardware development is a very important part of an engineer's education but it can also be a difficult phase that could lead to discouragement and loss of motivation in some students. Considering the previous constraints and first year engineering students’ high abandonment rate it is important to develop teaching strategies to deal with this problem in a feasible way. The solution that we propose is the integration of a low-cost standard robotic platform WowWee Rovio as an intermediate solution between the simulation phase and the stage where the students can develop their own robots. This approach will allow the students to keep working in robotic areas such as: cooperative behaviour, perception, navigation and data fusion. The propose approach proved to be a motivation step not only for the students but also for the teachers. Students and teachers were able to reach an agreement between the level of demand imposed by the teachers and satisfaction/motivation of the students.
