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
- As part of the Marine Geoscience strand of the new Bachelor of Marine Science, the Department of Earth and Planetary Sciences introduced a highly successful new first year unit, GEOS116 Marine Geoscience. The unit was run in a tailored problem-based learning (TPBL) format designed to develop a number of generic and science-specific skills concurrent with content delivery. The traditional problem-based learning approach was tailored to meet the needs of first year students coming directly from secondary education. The unit was closely evaluated throughout the semester, with surveys returning responses such as "good, challenging, fun - heaps different to other courses". The implementation of the approach was facilitated by a University Flagship grant awarded to members of the Department. In 2002, GEOS115 Earth Dynamics, Materials and the Environment will be repackaged along TPBL lines.
- A new degree, the Bachelor of Environmental Science in Environmental Geology began in 2001. The BEnvSc program is aimed at producing professional Environmental Geologists equipped with skills for employment in both urban geology and the resource sector. Students can also major in Environmental Geology within the BSc structure. Third year units to be taken by these students include GEOS315 Environmental and Groundwater Geophysics, GEOS377 Exploration and Environmental Geochemistry, and GEOS399 Soils. Students are routinely exposed to the state-of-the-art equipment in GEMOC's Geochemical Analysis Unit.
- The use of computer packages and web interfaces in Earth and Planetary Sciences is becoming a routine feature of content and skills delivery. Both geology and geophysics units incorporate packages used by industry into classroom and field teaching. Our portable computer lab was upgraded in 2001 (with University funding of $61,960) to ensure that student are able to access up-to-date computer software.
- GEOS224 Introduction to Field Geology was opened up to a wider clientele in 2001 including students enrolled in the new Marine Geoscience program. While the unit still covers an introduction to the traditional geological mapping skills and introductory GIS (with data transfer and mapping via the MAPINFO program carried out using the upgraded portable computers) there is added emphasis on the development of generic field and teamwork skills.
GEOS 224 Introduction to Field Geology, held at Keepit, NSW. Students combine working in the field and GIS in a regional mapping exercise.
GEOPHYSICS TEACHING PROGRESS 2001
- Collaboration in teaching and research between GEMOC and Geophysics at the University of Sydney continues.
- The named degree, Bachelor of Geophysics, continued in 2001 after its inception in 1998 to increase the visibility of Geophysics. It has evolved into the advanced geophysics stream in the Bachelor of Science degree.
- The Bachelor of Technology in Exploration Geoscience has a Geophysics strand initiated in 1999, streamed from 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 over the last five years have resulted in an excellent array of new instrumentation. Acquisitions include:
- GEOMETRICS G856 Proton Precession Magnetometer
- GEOSOFT, MODELVISION, EMVISION, ERMAPPER and Claritas Stratview R48 Seismograph
- Seismic trigger cable modifications
- ABEM SAS4000 Resistivity System and a LUND 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. 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. Reorganisation of course structures and acquisition of teaching infrastructure (computers, high-technology instruments, GIS units) have increased the visibility of geoscience and have resulted in the presentation of geoscience with an interdisciplinary and innovative approach using state-of-the art technology and concepts.
