CISR-ODE, A C plus plus framework with ODE solver for code based system dynamics simulation

Ordinary differential equations are used for modelling a wide range of dynamic systems. Even though there are many graphical software applications for this purpose, a fully customised solution for all problems is code-level programming of the model and solver. In this project, a free and open source C++ framework is designed to facilitate modelling in native code environment and fulfill the common simulation needs of control and many other engineering and science applications. The solvers of this project are obtained from ODEINT and specialised for Armadillo matrix library to provide an easy syntax and a fast execution. The solver code is minimised and its modification for users have become easier. There are several features added to the solvers such as controlling maximum step size, informing the solver about sudden input change and forcing custom times into the results and calling a custom method at these points. The comfort of the model designer, code readability, extendibility and model isolation have been considered in the structure of this framework. The application manages the output results, exporting and plotting them. Modifying the model has become more practical and a portion of corresponding codes are updated automatically. A set of libraries is provided for generation of output figures, matrix hashing, control system functions, profiling, etc. In this paper, an example of using this framework for a classical washout filter model is explained.

On- and off-campus engineering student usage of a computer conferencing system

This article reports on the introduction of a computer-conferencing component into a first-year study unit in technology management at Deakin University, Australia. It was found that significant variations in computer usage were correlated to student study mode, including source of computer access, source of Internet access, hours-per-week computer usage, regular use of e-mail, regular use of the Internet, number of times the conference was accessed, use of computers for games, and use of computers for learning. Other moderate differences were also noted. Following exposure to the computer conference, on-campus students were more likely to agree that computers could assist their learning, and off-campus students were less likely to agree that learning from computers would be better than classes/lectures.

Longitudinal study of computer usage in flexible engineering education

A longitudinal analysis of computer usage by commencing students in Deakin University's undergraduate engineering and technology programs over the period 1998 to 2001 revealed that; access to computers was at high levels; mean computer usage for off campus students had not changed significantly, but had risen significantly for on campus students; while access to the Internet / WWW had not increased significantly, reported regular use of the Internet / WWW had risen significantly; while most students continued to report their source of Internet / WWW access as either home or university, the proportion reporting home as their source of access had risen significantly; and the reported regular use of email rose significantly. Other results are also presented.

These results imply that commencing engineering and technology students are well placed to adopt online delivery and support of teaching and learning. However, while it might now be reasonable to assume that all students have access to computers and the Internet, the experiences of on campus students in computer laboratories with broadband network access will be different from off campus students accessing the Internet via a dialup modem connection. A small proportion of commencing students were unaware of the computing facilities provided by the university; an orientation program covering computing facilities and services would benefit all commencing students.

Comparative academic performance of engineering and technology students at Deakin University, Australia

Students completing three-year engineering technology and four-year professional engineering undergraduate courses may undertake a number of common study units. To gain an objective understanding of the academic performance characteristics of both student groups in the engineering and technology programs at Deakin University (Australia), a study was  undertaken of close to 9000 unit enrollments. It was found that: overall the BTech withdrawal rate was about 20% higher than for BE students; the rate of withdrawal was significantly different between the two student groups; the grade distribution for completing students was not significantly different between the two groups; the mean final grade was not significantly different between the two student groups; the failure rate was not significantly different between the two student groups; and the overall wastage rate (withdrawn rate plus fail rate) was significantly higher for BTech students. Other related results are also reported.

Framework for undergraduate engineering management studies

The importance of management to the long-term careers of practicing professional engineers has long been recognized. Undergraduate engineering education should therefore provide an exposure to the management skills required by engineers in professional practice. For the rational and effective design of undergraduate engineering management studies, it is essential to understand the nature of engineering management and to identify those management skills identified as important by practicing professional engineers. Through an investigation of the recent literature, the management skills considered important by engineering stakeholder groups are identified and ranked. This information is supplemented by recent surveys conducted by the author of stakeholders in Australia, including academic staff, mature age undergraduate students, and recent graduates of the engineering programs at Deakin University in Australia. Based on an examination of the literature and original research, a framework of ranked classified management skills is proposed. Broadly, the ranking framework is generic professional skills first, followed by general management skills and technical discipline specific management skills, followed by other professional discipline skills and theoretical skills.

Usage of a computer conferencing system by on- and off-campus engineering students

This paper reports on the introduction of a computer conferencing  component into a first year study unit in Technology Management at Deakin University, Australia. It was found that significant variations in computer  usage were correlated to student study mode, including source of computer access, source of Internet access, hours per week computer usage, regular use of email, regular use of the Internet, and number of times the conference was accessed. Other moderate differences were also noted. Following  exposure to the computer conference, on-campus students were more likely to agree computers could assist their learning, and off-campus students  were less likely to agree that learning from computers would be better than classes/lectures.

On-line support for students studying engineering management off-campus in summer semester

An on-line site was created to support students studying a time shortened, off-campus unit in engineering management that was being offered over summer semester for the first time. An evaluation exercise was undertaken to assess the effectiveness of this arrangement, to identify what types of on-line resources students rated as important, and to identify those on-line resources that students actually used in their summer semester studies. Most students reported that they were successful in achieving their summer semester study goals, and that summer semester study was as good as or better than studying in a standard semester. The types of on-line resources ranked most highly by students were those that assisted in strategic study and exam preparation. The on-line resource ranked as least important and used least in practice was a discussion forum for all students. Other results and statistical analysis are presented.

Review of first-year engineering and technology units based on student unit evaluations

There is recognition that the first-year of university study is a critical phase in the preparation, motivation and retention of science, mathematics,  engineering and technology (SMET) students. First-year provides the foundation/generic skills upon which students will base their undergraduate studies and professional practice; first-year is where many poorly prepared/at risk students will drop out and contribute to the poor student retention rate observed in the SMET disciplines; and first-year is when students may lose the motivation to pursue their chosen career direction if they find the studies at the commencement of their undergraduate program appear to bear no relationship to their intended career. In 2003, the Learning Resources Advisory Group of the Deakin University School of Engineering and Technology was requested to undertake a review of first-year units in the School’s programs. The information contained in anonymous unit evaluation questionnaires from the years 2000-2002 was used as the basis for analysing student perceptions of first-year units. In unit evaluations, students reported a wide range of issues that impacted negatively on their perception of the content and conduct of first-year units. It was noted that units service taught by other Schools form a significant element of the first-year of all of the Engineering and Technology undergraduate programs – typically 25 to 50 percent of the content. The significant influence of these units on the perceptions of the first-year of the School’s commencing students means that the School should exercise some control over the content and delivery of these units.

The learning outcomes of an online reflective journal in engineering

Reflective thinking based on experiential learning is a key skill required for the lifelong learner and the socially mature professional. Following several semesters employing a written reflective journal as an assessable task, a fourth-year engineering management unit adopted an online reflective journal. During the initial semester of use, an evaluation was undertaken to investigate student perceptions of the online journal. A summary of this previous work is presented here. Following three semesters of use of the online journal, an analysis of the student use of the journal was undertaken to investigate its contribution to unit learning outcomes. Based on the evaluation of student perceptions of the online reflective journal, it was found that a majority of students understood the purpose of the journal, and valued the journal in their learning; a majority of students read the journal entries of other students, and indicated that this assisted their learning; and the two most frequently reported ‘most useful’ aspects of the journal were the ‘enforced’ continuous revision of course material, and the ability to compare their understanding of the course material with that of other students. Based on a regression analysis of the factors related to student usage of the online reflective journal, it was found that the significant contributors to final unit mark where: prior academic performance; number of journal postings; and mode of study. This research confirmed that the online reflective journal was fertile territory in the landscape of educational technology, both in terms of student perceptions and contribution to unit learning outcomes.

Evaluation of Australian undergraduate engineering management education for flexible delivery

This thesis examines issues in Australian undergraduate engineering management studies in the context of flexible learning delivery. It is proposed that, within an Australian context: a) the management skills and competencies required by graduate engineers can be determined and classified on a rational basis, permitting an educational focus on those elements most appropriate for graduates; and b) on-line and other computer-based technologies are a practical and effective method for the support of undergraduate engineering management studies. The doctoral project incorporates: • an examination of the nature of engineering management; • a review of the relevant literature establishing the importance of management studies in undergraduate engineering courses; • a review of historical and recent developments in Australian undergraduate engineering management studies; • an investigation of the management skills and competencies required by graduate engineers - based on original research; • an examination of flexible delivery of engineering education - based on professional practice experience; and • an evaluation of case studies of flexible delivery of engineering management education - based on original research and professional practice experience. A framework of ranked classified management skills is developed. Broadly, the ranking framework is generic professional skills, followed by general management skills and technical discipline specific management skills, followed by other professional discipline skills and theoretical skills. This framework provides a rational basis for design of undergraduate engineering management studies. This is supplemented by consideration of the management skills required for the future of engineering practice. It is concluded that undergraduate engineering management education is well suited to delivery and support by on-line and computer-based technology. Recent developments in improved access to the Internet, software systems for on-line collaboration and changes in copyright legislation to create a broad-based right to communication via on-line media have contributed to the facilitation of on-line delivery of teaching and learning. It is noted that though many on-line infrastructure issues have been satisfactorily resolved, higher level issues will emerge as being crucial, including the academic staff development and reward for operating in an online teaching environment and the financial sustainability of on-line development and delivery of courses.

Advanced virtual engineering educational program for engineering research and teaching excellence

In this paper, an advanced virtual engineering educational program developed at University of South Australia for both on-campus and off-shore students will be studied. This extensive training program is based on a comprehensive online tutorial and comprises both face-to-face and online learning. The program provides a tailored evaluation format to ensure that all postgraduate students, including course work and research students, will have appropriate exposure to updated learning skills and research resources. Although the internet (WWW) is the primary resource being used in this educational program, other resources such as video conference, video taping, and face-to-face lecturing have also played a role in promoting engineering teaching and research excellence. The feedback from students in recent years has been very encouraging, showing increased information literacy skills and improved researching abilities. As off campus class numbers have increased, further development of the program to meet their requirement has been a priority.

Engineering management studies as part of continuing engineering education

Engineering management is an important area of undergraduate preparation. With the introduction of engineering and technology degrees via flexible delivery, there are a growing number of mature age engineering students returning to study to upgrade their qualifications. These students offer a new and unique perspective on engineering management - they may have had significant practical experience as a manager/supervisor in an engineering environment. This paper reports on a survey undertaken to better understand the perceptions of mature age engineering students relating to engineering management. The engineering management competencies identified as most important by mature age engineering students are those that are practically orientated, most clearly associated with engineering and generic professional skills. Management competencies identified as less important by mature age students are those that are more theoretical and most clearly associated with other business functions or professional occupations.

A systems approach to the engineering workforce

The engineering function, work force and associations should be viewed as a system, for an adequate understanding of the complex interactions involved, for development of coherent policies and for achieving optimal overall performance. Such an approach embraces professional, para-professional and other categories, and requires a coherent system of qualifications, education, occupational identifiers and role definitions. For engineering education, it facilitates effective design of educational programs for each category and educational articulation between them. For industry and society, it fosters work force effectiveness and harmony. The paper provides the basis for systematising the complex of elements that make up the engineering system.

An evaluation of a project-based learning initiative in engineering education

Project-based learning (PBL) is a well-known methodology for engineering design education due to a number of benefits it is claimed to offer. This paper presents the initial offering of a first-year engineering PBL unit at Griffith University in Australia. An evaluation of student perceptions of the unit revealed that students generally enjoyed the experience, with the oral presentation aspect receiving the lowest satisfaction rating. There was no significant difference in the ratings between any demographic grouping, suggesting that all students were able to participate in, and experience, the unit in essentially the same way. The best aspects of the unit and those aspects needing improvement were similar to the findings of other investigations documented in the literature. It is proposed that future offerings of the unit will reduce the number of design projects from three to two per semester and will attempt more sophisticated individualisation of marks for group work activities.
