GEMOC's teaching program aims to:
- provide undergraduate and postgraduate students with a broad, integrative understanding of Earth architecture and processes, bridging the discipline boundaries of geology and geophysics
- train undergraduate and postgraduate students in new conceptual approaches and the applications of advanced technology, including geochemical analysis techniques and the integrated field and laboratory use of geographic information systems (GIS)
- develop international links in teaching programs (especially postgraduate) relevant to GEMOC's goals
- develop formal tailored course work components at postgraduate level which also can be packaged for distance education delivery and as short courses available to the mining industry
- enhance the pool of high quality geoscience graduates by restructuring academic programs to attract a new clientele
HIGHLIGHTS 1999 - 2000
- A new degree, the Bachelor of Environmental Science in Environmental Geology is ready for its launch in 2001. Initial indications are that this will be a popular degree for both new and existing students. Students are also able to opt for a more flexible but similar program under the current Bachelor of Science degree. The BEnvSc program is aimed at producing professional Environmental Geologists equipped with skills for employment in both urban geology and the resource sector. Third year units to be taken by these students include GEOS 315 Environmental and Groundwater Geophysics, GEOS 377 Exploration and Environmental Geochemistry, and GEOS 399 Soils. Students are routinely exposed to the state-of-the-art equipment in GEMOC's Geochemical Analysis Unit. The program was constructed with advice from the GEMOC Advisory Board.
This degree can be combined with Law or Economics to complete a BEnvSc/LLB, BEnvSc/BEc, or undertaking postgraduate studies within the Department or the Graduate School of the Environment.
- The Department of Earth and Planetary Science is co-convening a strand of a second new degree, the Marine Geoscience strand of the Bachelor of Marine Science. The Department is introducing a new first year unit GEOS 116 Marine Geoscience, restructuring an existing second year unit in 2002 that will become GEOS 260 Marine Depositional Environments, and taking part in another broad second year unit, Marine Science in 2002. These changes are in line with both the long and short term aims of the GEMOC teaching program and in particular will include the further integration of geology and geophysics.
- An increasing number of Earth and Planetary Sciences units is coming on-line and including the use of computer packages in teaching to assist student learning. A new interface is being implemented to present a consistent format for the teaching sites to make them more accessible.
- Routine use of the GIS approach in undergraduate teaching continues. Students are introduced to computer-based mapping in their first field unit and use portable computers to construct maps. Macquarie funded replacement of these portable computers for 2001 ($61,960).
- The upgrade of teaching microscopes at Macquarie was completed
in 2000 with a grant of $120,000 (in addition to $89,000 from
GEOPHYSICS TEACHING PROGRESS 2000
- Collaboration in teaching and research between GEMOC and Geophysics at the University of Sydney continues.
- The named degree, Bachelor of Geophysics, continued after its inception in 1998 to increase the visibility of Geophysics.
- The Bachelor of Technology in Exploration Geoscience has a Geophysics strand initiated in 1999, streamed from the second year level (see flow sheet on Appendix 6).
- Use of an extensive pool of GPS units for undergraduate (and postgraduate) fieldwork continued. Subscription to time signal allows real time differential applications with mapping resolution of less than 5 metres.
- Extended implementation of new seismic, gravity and resistivity equipment for student field projects in exploration, groundwater, environmental and engineering geophysics.
- Equipment upgrades funded by Macquarie University have resulted
in an excellent array of new instrumentation. Acquisitions in
- GEOMETRICS G856 Proton Precession Magnetometer
- GEOSOFT, MODELVISION, EMVISION Software upgrades
- Bartington MS2 magnetic susceptibility-temperature system upgrade
- Seismic trigger cable modifications
- ARTEMIS TEM system with system upgrade ordered
OUTCOMES AT MACQUARIE
The introduction of new units and restructuring of existing
undergraduate units at Macquarie as described in each Annual Report
has achieved the goals of attracting new clientele and increasing
the visibility of geoscience. However, this is within an environment
of a contracting pool of science undergraduates. Despite this,
GEMOC core units at 100 level have maintained average enrolments;
200 units have maintained average retention rates of 33%; and
300-level units had retention rates for 2000 of 49% and 91% for
Geology and Geophysics core subjects respectively.
