Engineering education anywhere, anytime: from distance education to blended learning at Deakin University Australia

In 2005 the Sloan Consortium called for engineering education to be available "anywhere, anytime."* Increasing numbers of engineering departments are interesting in offering their programs by means of online learning. These schools grapple with several difficulties and issues associated with wholly online learning: course structure, communication with students, delivery of course material, delivery of exams, accreditation, equity between on-campus and off-campusstudents, and especially the delivery of practical training. Deakin University faced these same challenges when it commenced teaching undergraduate engineering via distance education in the early 1990's. It now offers a fully accredited Bachelor of Engineering degree in both on-campus and off-campus modes, with majors that include civil,mechanical, electrical/electronics, and mechatronics/robotics.This presentation describes Deakin's unique off-campus delivery, students, curricula, approaches to practical work, and solutions to the problems mentioned above. Attendees will experience how Deakin Engineering delivers course materials, communicates with off-campus students, runs off-campus classes, and even delivers lab experience to students living thousands of miles away from the home campus. On display will be experimental lab kits, video presentations, student projects, and online broadcasts of freshman lab experiments. Participants will have the opportunity to see some of these resources hands-on. I will also discuss recent innovations in off-campus delivery ofcourses, including how flipping the classroom has led to blended learning with the on-campus students.Many universities have placed engineering distance education into the too-hard basket. Deakin Engineering demonstrates that it is possible to deliver a full undergraduate degree by means of distance education and online learning, and modern technology makes the job easier than everbefore. The benefits to the professor are many, not the least of which is helping a student living in a remote area or with a full-time job become fully trained and qualified in engineering.

Comparative acoustic performance and mechanical properties of silk membranes for the repair of chronic tympanic membrane perforations

The acoustic and mechanical properties of silk membranes of different thicknesses were tested to determine their suitability as a repair material for tympanic membrane perforations. Membranes of different thickness (10-100μm) were tested to determine their frequency response and their resistance to pressure loads in a simulated ear canal model. Their mechanical rigidity to pressure loads was confirmed by tensile testing. These membranes were tested alongside animal cartilage, currently the strongest available myringoplasty graft as well as paper, which is commonly used for simpler procedures. Silk membranes showed resonant frequencies within the human hearing range and a higher vibrational amplitude than cartilage, suggesting that silk may offer good acoustic energy transfer characteristics. Silk membranes were also highly resistant to simulated pressure changes in the middle ear, suggesting they can resist retraction, a common cause of graft failure resulting from chronic negative pressures in the middle ear. Part of this strength can be explained by the substantially higher modulus of silk films compared with cartilage. This allows for the production of films that are much thinner than cartilage, with superior acoustic properties, but that still provide the same level of mechanical support as thicker cartilage. Together, these in vitro results suggest that silk membranes may provide good hearing outcomes while offering similar levels of mechanical support to the reconstructed middle ear.

Australasian partnership in a first-year engineering course: Deakin University and Wuhan University of Science and Technology

This paper presents the results of domestic Chinese undergraduate engineering course taught by international Australasian teaching staff. The project is a part of a teaching collaboration between Deakin University and Wuhan University of Science and Technology. The cohort of students from Wuhan was a freshman undergraduate engineering course in mechanical engineering. The particular subject was a freshman engineering-materials course taught in English. The course covered an introduction to material-science principles and practices. A survey was used for evaluating student perceptions. It is aimed that this study will help academics from Deakin University to better understand student experiences, and to identify the current challenges and barriers faced in student learning. Analysis of the survey has shown that 90% of students agreed that they were motivated to learn and achieve the learning goals through this collaborative program. Around 90% of students found that group-based practical activities were helpful in achieving learning goals. Overall, 90% of students strongly agreed they were satisfied with the method of teaching.

Biocompatible and biodegradable Mg/Mg composite foam for bone tissue engineering.

This thesis focuses on studying solid and porous Magnesium-composite structures. Magnesium is attracting increasing interest as promising biodegradable material for medical applications; however, suffering from low mechanical properties. This thesis suggests the manufacturing and application of a new approach that is high str
