GEMOC ARC National Key Centre

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

Highlights 2004

Curriculum Development

• Our tailored problem-based learning (TPBL) units GEOS116 Marine Geoscience and GEOS115 Earth Dynamics, Materials and the Environment continue to be revised and were, again, well received by students. The format includes lectures, problem-based workshops and traditional skill-based practicals. The workshops are completed as group work projects and are modelled on real-life scenarios with the students adopting a role as part of a geoscience team.
  

• GEOS377 “Environmental Geology” was redesigned with the help of a Macquarie University Teaching Development Grant. The project was titled: Bringing the workplace into the classroom – the redesign of GEOS377 using Tailored Problem-Based Learning and real workplace scenarios. This unit utilised the TPBL model but also aimed to introduce professional and generic skills that are seen as important by employers of graduates in the environmental geology area.

• The unit is based around 3 projects that develop scientific problems from an initial tender stage to the preparation of final reports. All work is completed as group work with students taking the role of small consulting teams. GEOS377 Environmental Geology is a core unit of the new Bachelor of Enviromental Science in Environmental Geology.

Nathan Daczko co-ordinated three units in 2004 - GEOS115, GEOS230, and GEOS307. GEOS230 Field and Laboratory Studies in Geoscience was run for the first time. This 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. Laboratory techniques covered include petrographic microscopy, x-ray diffraction, x-ray fluorescence, electron microprobe, geoscience computing and the construction and interpretation of geological and other maps. A new field trip to the historic gold mining town of Hill End provided an excellent opportunity to apply these laboratory practices in the field. This new unit attracted 19 students from the Department of Earth and Planetary Sciences in 2004 and will be offered externally for the first time next year.

• GEOS307 Field Geology and Mapping was again run in the Broken Hill/Olary region in conjunction with the University of Sydney. Field studies in the Broken Hill/Olary region allow students to gain experience mapping in a geological province not encountered before in their course. The unit attracted 21 students from the Department of Earth and Planetary Sciences in 2004.

• Another successfull field-based unit GEOS373 “Volcanic Geology Fieldwork”, centred on a trip to New Zealand, was run again in 2004.

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. Our portable computer lab allows students access to up-to-date computer software for use in both the classroom and field.

Geophysics teaching progress 2004

• Collaboration in teaching and research between GEMOC and Geophysics at the University of Sydney continues.

• The named degree, Bachelor of Geophysics, continued in 2002 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 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 software was either purchased or upgraded

• Seismic trigger cable modifications

• ABEM SAS4000 Resistivity System and a ABEM LUND system
• ASHTECH Z-Xtreme Differential GPS system
• DUALEM Frequency Domain EM System

Outcomes

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.
