Abstract: In the areas of engineering education due to various shortcomings of
the traditional laboratories, virtual laboratories have appeared as a
potential alternative to traditional laboratories. Every system – mechanical,
electrical, biological– can be accurately described by a mathematical model.
The models can be applied in practice because the computers allow us to solve
it in a numerically way. In this paper, we focus on the theory of the
modeling, applied on the areas of electrical machines. Three key problems are
discussed in this application: the purpose, the content and the impact of such
a laboratory in studying and learning the scientific and engineering
principles of electrical machines areas.

Abstract: Many lecturers question the necessity to incorporate changes in the
methodology of their subjects and the lack of instruments to verify if the
changes that these active methodologies have a desirable effect. In this
sense, the validation of the JDS adapted to university teaching, allow to fill
up this deficiency. Any lecturer that want to know the satisfaction of
students with his teaching, have with this tool a robust procedure that can
complement or clarify the information that arrives by the student’s surveys or
other sources. The model consists of seven scales that measure the
characteristics of the job as well as an indicator of the motivate profile of
the work (MPS) and six scales of satisfaction with diverse aspects of the job.
The scales vary significantly when we compared the data obtained from an
experimental group with active methodologies teaching with respect to two
control groups with traditional teaching. The adapted version of JDS scales
has suitable values of internal consistency. Only the models hypothesized with
correlated factors, display accepted values respect to the reliability of
construct and the variance extracted and also the best values of
goodness-of-fit indicators.

Abstract: A regular subject of a degree course can be split into 4 main parts:
Lecturing classes, hands-on skills, homework exercises and in-class exercises.
There are many researches on lecturing classes and hands-on skills and,
although there are many related with homework and in-class exercises, they are
focused on the methodology more than of the type of media used to perform
them. Homework and in-class exercises have the objective of the reinforcement
of the knowledge learned in lecture classes. Generally, these problems or
exercises are presented written in a paper or, sometimes, in an electronic
format using a word processor or pdf. Despite of the type of exercise or
problems proposed for the students, we suggest the use of multimedia
activities as a medium to propose these exercises. In this paper we will show
different kind of multimedia activities that can be used for homework and
in-class exercises. This classification will allow us to choose the type of
multimedia activity depending on the type of knowledge that it is wanted to
transfer to the student. These multimedia activities have been used in the
subjects “Redes de Area Local” and “Integracion de Redes” that are lectured in
the third course of the Telecommunications Technical Engineering in the higher
Polytechnic School of Gandia of the Polytechnic University of Valencia. We
will show the measurements taken from a questionnaire presented to the
students and we will discuss their results obtained. We will also compare the
marks of the students in both subjects in the last two course years.

Abstract: Some practical approaches have been presented successfully, which
can be applied for control engineering education. Compared with conventional
lecturing and laboratory exercising, instructing outcomes can be improved
significantly. Two independent sets of instruments from Feedback Instruments
Limited are selected to conduct experiments on a basis of the fundamental
control theories. In particular, the 33-110 servo system is selected,
consisting of three components: mechanical unit, analogue unit and digital
unit. The 150 servo system contains a number of major discrete component
units. Both systems can be used to test the fundamental control principles,
such as the PID control. Matlab is employed for data analyzing, simulation,
plotting and programming. Simulink is also employed to implement numerical
simulations for advanced control practices. For practical control problems in
real time, such as robotic control and engine control, Labview can be applied
considering its merits of the graphical user interface design and block
diagram approach. Some typical examples to improve classes at the system and
control laboratory are presented, using software or hardware instructing tools
such as the Matlab, Simulink and Labview.

Abstract: Since opting to Outcome Based Education method, the teaching of the
subject Material Technology had resorted to problem-based learning method to
achieve the outcomes attributed to this course. For the students to attain
communication skill and life-long learning, problem-based learning is utilized
to replace traditional lectures and laboratory works. Traditionally, lectures
are given for 28 hours in a 42-hour per semester course and the rest allocated
for laboratory works. In the newly endorsed method, the lecture hours are
reduced to 14 hours and the rest is for presentation and seminars by the
students. As for laboratory work, instead of doing individual experiment with
individual report, the whole laboratory work for the semester is designed as
components of a project. The results of the transition are: the students are
more interested to attend class especially during presentation sessions where
they provide high commitment; for a descriptive-form courses, such as
Materials Technology, boring lectures can be made interesting by the students
themselves presenting the materials with the lecturer’s guide and as for the
laboratory work, no more free riders and lack of understanding the
relationship between individual experiment with the problem to be solved. The
work load of the students is calculated using the definition of notional
credit hour and the new improved delivery method for this course still
maintain the three credit allocation.

Abstract: The creation of knowledge from information can be promoted by proper
representations of information which make the inherent logical structure of
the information transparent. Since concepts are the basic units of human
thought and hence the basic structures of logic, the logical structure of
information is based on concepts and concept systems. Methods from the theory
of formal concept analysis and frequent set mining are applied for automated
extraction of information from students’ responses to preliminary tests about
their lack of knowledge or misconception of fundamental terms and skills.
Personalized recommendations are suggested to each student once possible
difficulties in learning a new subject are detected.

Abstract: An accurate training on measurement techniques and measurement
system design can be obtained by carrying out real experiments with real
electronic components and circuits. The measurement system presented in this
paper performs the computer aided study of the bending stress sensor. This
experimental system is very useful for engineering undergraduates because they
can test the theoretical knowledge about measurement techniques, sensors and
transducers, signal conditioning circuits, data acquisition boards, signal
processing methods and computers (hardware and software). The bending stress
sensor consists of four strain gauges connected in a full-bridge circuit, and
it transforms the load or force into measurable voltage change. An
instrumentation amplifier and a noise suppression circuit and amplifier are
designed for conditioning the output voltage of the bending stress sensor. The
computer aided study of this sensor imposes a data acquisition board with a
microcontroller, adequate software and a friendly user interface. The
procedure for strain gauge sensor study supposes the following four stages:
assignation of the measurement points, plotting the transfer characteristic of
the force transducer, computing some parameters of the force transducer (zero
error, differential sensitivity, relative sensitivity), weighing some objects
using the strain gauge sensors. The architecture and design considerations for
signal conditioning module and data acquisition board are also presented in
this paper.

Abstract: The article acquaints readers with over four-year experience with
virtual mobility gained during development of the network of interuniversity
study in the Czech Republic. Virtual mobility represents utilization of
information and communication technologies to obtain the same benefits as one
would have with physical mobility but without the need to travel. The
contribution describes two projects based on the issue of virtual mobility.
The system of interuniversity study is depicted; special attention is devoted
to the efficiency of virtual mobility. The efficiency is in this paper
understood as a difference in numbers of students who got enrolled in courses
at the beginning of the academic year and those who completed courses
successfully at the end of the year. Reasons of the unsuccessful study are
explored in detail.

Abstract: The paper proposes an easy extraction path of almost static and
dynamic parameters of a power MOSFET based on a laboratory technique that
requires only one test circuit. Hard switching the power MOSFET on a resistive
load, the gate charge, the forward transconductance, the on-state resistance
and the switching times, and the intrinsic capacitances are extracted from the
waveforms of the gate voltage, drain voltage, and drain current. The
extraction procedure for all these parameters of device is described step by
step in the paper. A simple test allows students to evaluate the switching
performance of a power MOSFET and to teach the difference between MOSFET
technologies comparing the Figure of Merit (FOM) index of devices. This test
can be repeated for many MOSFETs and IGBTs to compare their overall switching
performance and to observe the device behavior for various operating
conditions of the device under test (resistive or inductive loads and
different supply voltages, and drive gate currents) and it can be used as an
education tool in Power Electronics at its basic level.

Abstract: Experiments play an essential role in teaching earthquake
engineering because the response of the structures is of dynamic nature and
students are not usually accustomed to earthquake loads. Fortunately, severe
earthquakes have long return periods, thus testing models in a shaking table
until collapse is the best way to make the students understand the effects of
earthquakes on structures and stimulate their interest on the field. However,
testing a structure on a shaking table up to collapse can be dangerous and it
is not feasible in the physical presence of a large number of inexperienced
students. This paper presents an innovative approach for teaching earthquake
engineering, based on an enhanced distance learning system, that uses
synchronous ("video streaming") and asynchronous ("e-learning platforms")
technologies. An extensive use of online educational tools are proposed to
motivate students' participation in dynamic tests and competition for
predicting the responses. As an example of implementation, a recent experience
at the University of Granada is described. Here, several shaking table tests
on two half scale models are combined with numerical simulations aimed at
predicting the observed response. Based on this experience, the advantages and
practical problems from the perspective of engineering are identified. In
closing, several recommendations are made for improving the results of this
teaching method.

Nevertheless, a prospective experimenter is also encouraged to perform tests
by using Linux operating system and appropriate solutions that come with that
OS. In addition to the opportunities for experimenting with repeater programs
for personal computers, networking procedures and commands are implemented in
non-computer, or so-called 'hardware' types of radio relay devices. This work
suggests the readers a couple of basic methods of communication in a wired

Title of the Paper: The Challenge of
Implementing a Student-Centred Learning Approach in Large Engineering Classes

Authors: Cristina C.
Danko, Antonio A. L. S. Duarte
Abstract: The renovation of teaching and learning methodologies, promoted by
the onset of the Bologna Declaration, is leading to shifting perceptions of
roles and responsibilities of both teachers and students. Particularly in
large engineering classes, certain subjects benefit from more active
approaches to learning, namely those associated with team work and tutorial
practices, rather than traditional lecture/teacher-driven presentations.
Project-led education (PLE) and Project/problem-based learning (PBL) are
successful student-centred teaching strategies by directing team work towards
independent learning. These new approaches transfer the teacher’s role from a
mere transmitter of knowledge to that of advisor and facilitator of the
learning process, by providing guidance and suggestions designed to encourage
students to find their own solutions for proposed problems. This paper
describes a methodology for promoting and encouraging independent team work
using tutorial techniques for the practical sessions of the Environmental
Impact Assessment course (mandatory and elective) included in the Civil
Engineering programme at the University of Minho. The authors were faced with
a multi-faceted problem: managing and motivating a large class of civil
engineering students in a transdisciplinary and non-traditional civil
engineering setting. So, they decided to implement a project-based strategy
aiming to foster the development and enhancement of student /skills and
aptitudes. The learning objectives were well-defined, as well as a set of
pre-scheduled tutorial meetings for team work monitoring and assessment. The
overall project goal was to conduct a critical analysis of one or more cases
concerning environmental impact assessment, in view of the concepts
apprehended in lecture and through literature review of pertinent documents
and applicable regulations. The students were pleased with the requirement to
use and critically analyse procedural documents and regulations, favouring a
broader understanding of the subject. The opportunity to study and analyse
real cases was referred as a particularly positive aspect of this methodology,
which allowed for another learning dimension towards the development of
professional competencies. At the end of the semester and upon submitting the
final written report, each student was required to conduct a simple exercise
of self and peer-assessment. The results of the Teaching/Learning Evaluation
institutional survey were used to determine how successful the implementation
of the new EIA course design had been, and, overall, both instructors and
students considered the implemented methodology to be positive and suitable.
The ability to conduct independent work and the freedom to manage their own
work schedules were particularly appreciated, especially by students with
heavier workloads from other courses. The experience described represents a
significant move towards innovative approaches for handling and motivating
large engineering classes in a transdisciplinary context, by encouraging
active and collaborative learning activities, and by leading with real-world
problems.

Abstract: Employers nowadays place main concern on and give emphasis to
employability skills in potential engineers which caused a significant
increase in unemployment among engineering graduates in Malaysia. There are
several discussions and studies on “What types of skills and abilities are
needed in the workplace?” How the government and higher education overcomes
this rising phenomenon? This study attempts to look into engineering
employability skills that have been required for their new engineers by other
countries in Asia such as Malaysia, Japan, Singapore and Hong Kong. This paper
will put forward a list comprised of the essential skills needed by these four
countries, and compare the existing similarities and differences of these
enlisted skills. Information was gathered from articles, journals, papers and
reports. The findings indicate that these countries have published reports on
the necessary frameworks of employability skills to prepare engineering
graduates for the employment today and in the future. Overall, the studies
suggest that the engineering graduates should acquire a set of generic skills
such as communication skills, problem solving and interpersonal skills.

Abstract: The modern design of office buildings shows a tendency to increase
the window share per facade to be more impressive with grand visibility and
well daylit rooms. An increased window share in general results in an
increased use of energy and costs for cooling, but these disadvantages can be
reduced with a more careful design. The aim of this paper is to show the
influence of window design and room layout on cooling demand and daylight
availability in office buildings in Northern Europe. The results in the paper
are based on design calculations for two different room types and daylight
measurements on two room scale models in a daylight laboratory. Calculations
show the influence of window design parameters on the cooling demand. The
daylight measurements show the influence of window design parameters on the
availability for daylight. The results have then been combined to show
feasible window design regarding daylight availability and resulting cooling
demand for different window orientations. The results show that, in most
cases, it is possible to find a combination of window share and window solar
factor that is feasible from daylight as well as cooling point of view. The
main finding is that there is a smaller or wider range of feasible design for
different window orientations. Here, the product of window share and solar
factor is introduced as a guideline to find feasible designs.

Abstract: Nowadays, it is an evidence considering the Knowledge Society as a
result of advances in Information and Communication Technologies (ICT) where
people from all over the world have many benefits from the technological
progress. In this sense, it is clear that the introduction of ICT in education
has changed the traditional way of teaching and learning and forced the
teachers and students to adapt their technical abilities and knowledge of ICT.
Generally, the ICT support can be retrieved in teacher training programmes,
education management and information systems, educational content, distance
learning, education policy, media outreach and assistance for equipment and
related facilities. But the implementation of ICT in the teaching/learning
process mainly conducted to the change of the educational perspectives and
instruments. One of the best examples is given by the e-learning technology
which promotes modern methods of interaction by using ICTs. E-learning
technology is also proposed as an educational technology in many educational
projects where initial and in-service teachers are the main actors who work
inside different e-platforms. Courses, training modules, tasks and homework,
surveys and assessment forms have been proposed together with other solutions
that enhance the participation of teachers for working in a collaborative way.
In this respect, the three years European Socrates Comenius 2.1 Project
“VccSSe - Virtual Community Collaborating Space for Science Education”
(128989-CP-1-2006-1-RO-COMENIUS-C21) tried to promote the use of virtual
instrumentation and virtual experiments in educational environment, like new
and modern teaching methods for the Mathematics and Science teachers. Taking
also into consideration that the training sessions were developed using the
Moodle course management system, the paper illustrates some considerations
related to the training process made in the frame of the mentioned project and
other aspects regarding the advisability of the training modules “Virtual
Instrumentation in Science Education”, on the basis of the participants’
opinions emphasized in the project web-assessment forms.

Abstract: Effective and efficient communication and collaboration is a
prerequisite for the success of a project. This paper presents the numerical
data which relieve the amount of the collaborative activity developed through
collaborative platforms in the frame of two European educational projects
during around one thousand days of these projects life-time. The paper extends
the research presented in [7] by including the data of the last four months of
the two projects considered. The aim of this paper is to show how much a
collaborative platform can be used during a three years educational project
life-time and what types of project activities requests a more intense use, in
terms of quantity, of these platforms. For this evaluation, it is proposed a
method which has as basis the processing of the statistical data from the log
files generated by the web server which hosts the collaborative platforms.

Abstract: Questionnaires investigating foreign language acquisition in
engineering via traditional or web-based methods are versatile, allowing the
collection of both subjective and objective data through the use of open or
closed format questions. Modern computers have only made the task of
collecting and extracting valuable material more efficient. Just as well, they
have made English learning easier, more interactive and accessible. Therefore
we are currently confronted with clear progress and a shift in teacher/student
roles, whose impact must be thoroughly investigated in point of effectiveness
and possible unwanted side effects. However, a questionnaire is only as good
as the questions it contains, and as relevant as its respondents/pools of
subjects are. Many standards must be met before a questionnaire can be
considered a sound research tool. The majority deal with making the
questionnaire understandable and free of bias. Mindful review and testing are
necessary to weed out minor mistakes that can generate significant changes in
meaning and interpretation. When these guidelines are followed, the
questionnaire becomes a powerful and economic evaluation tool. Additionally,
when it is designed and applied together with students, it becomes a valuable
instrument for developing their research abilities and furthering both their
theoretical background and field research skills. The present questionnaire
constantly generated data in 1999-2009, a relevant decade in investigating the
Romanian learning and labour markets, and is a subsequent implementation of a
Leonardo da Vinci program entitled: Recipes for successful e-language
teaching, Guidelines for the implementation of effective and dynamic language
teaching in ODL environment.

Abstract: This project presents some new problems facing the study process in
the distant learning system (DLS), and also tries answering the central
question: “Why do we need personalized e-learning curricula?”. Web application
was developed in order to detect changes in learning styles and measure the
level of satisfaction of the students with the presented e-curriculum for C++
programming language. This research would contribute to creating those type of
learning objects which will be preferred for each student with different
learning style. Also, the data collected from the students can help educators
in choosing type of learning activities or in the design of those activities
which can suit all types of learner.

Product Development Methods with Activity Theory to Trigger New Concept
Generation

Authors: Denis A. Coelho
Abstract: This paper reviews literature on product development established
processes, showing how these emphasize requirements specification as a
starting point in new concept generation. Rather than limiting inputs for new
concept generation to verbal requirement lists, industrial design students
seem to prefer to be stimulated with ideas in context. Activity theory is
considered to the benefit of many human activity processes, as the fundamental
ground-laying theory on this matter illustrates. A new method that takes as
point of departure human activity to search for new product concepts was
developed and is presented in this paper. It supports pushing the envelope of
creativity beyond the mere upgrade of existing concepts. Systematic design
procedures are also used to evaluate and improve the initial concepts and
guide their development. Paradigm shift may represent a great opportunity but
also a challenge for widespread adoption of new concepts. The proposed method
is put into perspective with activity based methods for systems design. The
paper concludes with further application area suggestions for activity theory
within the engineering domain.

Abstract: Critical to any form of assessment is accountability. In the
educational arena for example, teachers are accountable to themselves, to
their students and the families, to schools and society. Portfolios constitute
an evaluation practice increasingly implemented both in instruction and in
employment procedures. The process of selecting evidence for inclusion in
portfolios involves ongoing dialogue and feedback between participants and
service providers. Portfolio assessment of the program or participants
provides a means of conducting evaluation throughout the life of that program,
addressing the evolving needs and assets of the participants and of the
community involved, helping to maintain focus on program outcomes and on the
steps required to meet them. Well-designed portfolios represent important,
contextualized learning that requires complex thinking and communication
skills. Traditional tests have been criticized as being insensitive to local
curriculum and instruction, and assessing not only student achievement but
aptitude. Portfolios are being heralded as vehicles that provide a more
equitable and sensitive portrait of what students know and are able to do.
This modern method encourages teachers and schools to focus on important
student outcomes, provide parents and the community with credible evidence of
student achievement, and inform policy and practice at every level of the
educational system.

Abstract: The formation of engineers involve enabling students in their own
specialty knowledge, and, in skills related with critical thinking,
reflection, argument development with verifiable and sustainable evidence,
discussion management, negotiation and consensus solutions, and convincing,
allowing them to improve the decision-making. This research contributes to the
study of argumentative discourse, introducing a pilot scheme which is to
characterize how students gathered in groups to argue their positions during a
speech to their peers, via the Internet, to solve a mathematical problem. The
study focuses on the connection between the academic performance of the
students and the activities of building knowledge. Besides that,
epistemological, argumentative aspects and pattern of dialogue are considered.
The research is classified as exploratory, descriptive and experimental
design. The methodology is a combination of proposals by Weinberger, Chang,
and the author. A Case Study was used, specifically the Problem Solving to
design tasks. A Virtual Classroom was built under Moodle platform, where there
were exercises materials, interactive program to study, and self-assessment
links to related books, etc, available to the students. In this place,
discussion forums were developed without a teacher’s presence in order to save
the students messages that come from the discussion to do the task. In order
to analyze the results of the investigation, it is taken as an analysis unit
the full message posted by each student: all messages were coded by two
different researchers, and then the Kappa coefficient was 82%. Among the
results obtained is a large proportion of interactions that reflects a correct
handling of the relationship between the given problem and the theoretical
foundations to applications in specific situations, showing a good level of
knowledge construction. However, the new approaches and ways of solving
problems were few. Often, the students ignored the messages of other members
of the group, leading to a repetition of the issues that were previously
raised and, therefore, most of the discussions were not focused on the task.
No evidence different to the result of the mathematical calculation was
presented. Although the social interactions were out of this research, it was
clear that the members of the group did not get rapport between them and,
consequently, the engagement to participate in the forum activities was not
strengthened. For all these reasons, there is not a enough evidence to ensure
that the academic performance of the students make be better using these
strategies. Finally, to optimize the successful implementation of this type of
methodological strategies, the presence of the teacher in the discussion
forums should be considered so that he performs the necessary interventions to
guide students towards constructing knowledge.

Abstract: This paper discusses a comprehensive study of employers’ perception
and expectation of Malaysian engineering graduates towards assessing
measurable qualities. To have better overview in this issue, a survey on the
needs, perception and expectation of Malaysian industries towards graduate
engineers is conducted. In order to create a smoother transition from
education to practice, some argue that engineering education should put more
emphasis on the engineering-based knowledge. Thus, this study investigates
also the gap analysis which is defined as the difference between expectation
and perception among majority of Malaysian industries towards existing
engineering graduates. Literally, it is to investigate the discrepancies
between employers’ perception and expectation towards future engineering work
force of all the sectors or industries in Malaysia for non-technical and
technical proficiencies. For the purpose of this paper, both technical and non
technical attributes are analyzed and discussed. A total of 422 companies from
various industries in Malaysia were chosen for the face-to-face interview
sessions using a set of questionnaires. The respondents were mainly from high
ranking personnel in their firm. The outcomes of this study will later be
considered as a revision guideline for the engineering education curricula of
Malaysian Institutions of Higher Learning.

Abstract: In visual applications, the color and width of an object’s outline
determine the feelings invoked in the viewer. This study investigates the
effect of the outline color and width on the preference of young children for
objects presented in PDA-based learning applications. The impact of three
different outline colors [the original object color, a darker color of the
same hue and saturation as the original object color, and black] and three
different outline widths [1 pixel, 2 pixels, and 4 pixels] on the visual
preferences of young children is examined in a series of experiments conducted
with kindergarten and elementary school students in Taiwan. The analysis of
variance results suggest that young children prefer the outline of the object
to be the same color as the object itself or at most to have a thin frame with
the same color as the original object, but with a slightly darker shade.

Abstract: The implementation of outcome-based education (OBE) curriculum in
the university syllabus nowadays plays an important role in producing quality
graduates students. Assurance to the effectiveness of OBE, a steady and
continuous assessment must be carried out through each course as well as the
industrial training program. This paper discussed the perceptions of the
undergraduate students from Civil and Structural Engineering Department who
have undergone their industrial training program. Questionnaires were prepared
and summarized into three main aspects i.e. 'personal attitude',
'communication' and 'work attitude' of the students before and after the
training program. The results show that the overall student's performance
before the training averaging from 48% to 63% for these three main aspects.
Interestingly the percentage has tremendously increased to 89% - 95% after
completion of the training program. This proved that the OBE implementation in
university syllabus is beneficial for improvement to the engineering education
and engineering profession in general.

Abstract: Aware of the qualities besides knowledge which are most valued by
engineering firms (the ability to make decisions, a capacity for teamwork,
initiative, capacity for solving problems and efficient communication, among
others), an experience based on Problem-based Learning (PBL) has been carried
out in which students have had to decide on what they understand as critical
thinking and participation in multi-task teamwork in order to self-assess
their own participation and critical thinking and evaluate that of their
team-mates. A quantitative analysis of the grades indicated that there were no
significant differences except with regard to the students’ preparation time.
A qualitative analysis showed that the students experienced the process as one
similar to that of facing their professional future.
