Beth Cavallari Beth Cavallari is the Head of Educational Multimedia Services (EMS) which is part of the Teaching and Educational Development Institute at the University of Queensland. EMS develops educational multimedia software and other materials for flexible delivery for the University and for a variety of external clients. Beth's main role is management, although she is sometimes part of a development team, providing instructional design and evaluation. She is also involved in lecturing with the Graduate School of Education at the University of Queensland. Beth was a teacher and Education Consultant in the New South Wales Department of School Education for 15 years before taking on a university role. At the University of Wollongong in New South Wales she worked as an Instructional Designer for three years before moving to the University of Queensland. Beth has been involved in the design and development of more than thirty multimedia software programs, including two award-winning packages, Backman! and Lake Iluka. Geoff Hamer Geoff Hamer started working in the IT industry in the swinging sixties, when he joined the Universities and National Research Division of ICT (now ICL) in the UK, selling the 1900 series computers against the main competition of the day, the IBM 360 series. His favourite prospect was the Physics Department of St Andrews University, because of their proximity to the Royal and Ancient Golf Club. Unfortunately, they purchased an IBM 360/44. Geoff came to the University of Wollongong as Manager of the Computer Centre in the mid seventies, after a brief and frustrating stint at the Port Kembla steelworks, coordinating the metrication of the plant's production systems. The University had just ordered its first mainframe, a giant Univac 1106, with half a meg of memory, 200 megs of disk and 16 terminals. The 1106 did everything - student Fortran and Basic exercises, on-line training in a range of software tools (an early CAL application), statistical and finite element analyses for students and researchers, payroll, student records, library systems - you name it. The computer was also the base on which a successful bureau business was built -which in the ensuing years funded much needed hardware enhancements and student lab equipment, as well as a computer trainee scheme. With the advent of low cost entry machines and desk-tops, the bureau business faded away and Geoff's team moved smoothly and naturally into the growth fields of CBT and CAL - developing interactive multimedia programs for both industrial clients and University and DEET-funded academic staff. In 1994, this team became a key component of CEDIR, the new department set up by the University to assist university teachers in the development of distance and flexible delivery teaching programs.
