Teaching and Training Program
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
- Once again our tailored problem-based learning (TPBL) units GEOS116 Marine Geoscience and GEOS115 Earth Dynamics, Materials and the Environment were well received by students. This format, which includes lectures, problem-based workshops and traditional skill-based practicals is designed to encourage the students to become more active learners and to develop a range of generic skills. The workshops are completed as group work projects and the students are required to produce scientific reports based on the results of their investigations. Generic skills developed include teamwork, problem-solving, critical thinking and written and verbal communication.

- GEOS230 Field and Laboratory Studies in Geoscience was run successfully in 2005, including being offered externally for the first time. This new unit uses projects integrated with lectures and laboratory classes to develop the theoretical knowledge and hands-on experience needed to map, describe and interpret rocks (and other materials eg soils, fossils, etc) in the field and the laboratory. One popular component of the unit is a forensic science murder mystery where an academic staff member has been murdered and three other staff are the key suspects! Many arguments ensue amongst the students over who did it. This type of project increases the student engagement with the unit content and leads to better retention of the key concepts. Once again the unit included a field trip to the historic gold mining town of Hill End.
- GEOS307 Field Geology and Mapping was run by Dr David Durney in 2005 for last time before he retires, bringing the end of an era. Field studies near Eugowra in the Forbes region of NSW allowed students to gain experience mapping deformed and varied geological units. The unit will return to the Broken Hill region in 2006.
- A number of students attended the GEOS381 Special Interest Seminar field trip to New Caledonia in 2005 run jointly with The School of Geosciences at The University of Sydney. They enjoyed great weather. The highlight of the trip was the spectacular exposures of blueschist and eclogite in the NE of New Caledonia.
- Our portable computer lab was upgraded in 2005 with the purchase of new laptop computers. This facility allows students access to up-to-date computer software for use in both the classroom and field. The use of computer packages and web interfaces in Earth and Planetary Sciences continues as a routine feature of content and skills delivery. Both geology and geophysics units incorporate packages used by industry into classroom and field teaching.

Geophysics teaching progress 2005
- The named degree, Bachelor of Geophysics, continued in 2005 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 in Appendix 6).
- Use of an extensive pool of GPS units for undergraduate (and postgraduate) fieldwork continued.
- Extended implementation of new seismic, gravity GPS 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, SeisImager and Claritas software was either purchased or upgraded
- Seismic trigger cable modifications
- ABEM SAS4000 Resistivity System and an ABEM LUND system
- ASHTECH Z-Xtreme Differential GPS system
- DUALEM Frequency Domain EM System
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 enrolment levels. 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.
