the teaching aims
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
this program has four short-term objectives:
- to reform the undergraduate curriculum
- to strengthen Geophysics training
- to introduce GIS-based philosophy and practice to both fieldwork and laboratory work
- to introduce a general-interest course to attract different clientele
achievements 1996 - 1998
During the first three years of GEMOC we have largely realised our short-term objectives and made substantial progress toward the relevant teaching aims. Flow sheets defining course structures are set out in Appendix 6. During 1998, publicity and outreach continued through the established channels of career markets, brochures and school visits, with the innovation of inviting year 11 students to attend a lecture and/or practical session in GEMOC. The Geochemical Analysis Unit hosted these sessions in 1998.
The great outdoors: students participating in GEOS260, Lithospheric Environments.
- The undergraduate curriculum has been reformed to attract a wider clientele, to reflect the changing interests of students, and to incorporate the new conceptual approaches and applications of advanced technology made available through GEMOC.
- In Planet Earth (GEOS112) we have successfully introduced a 3-day voluntary field trip which combines geoscience research with an outdoor experience. This popular field trip will be continued in 1999.
- In Earth Dynamics, Materials and the Environment (GEOS115) the curriculum has changed to include a greater emphasis on map reading skills and the way in which people interact with the geologic environment. Our newly refurbished teaching space allows small group tutorials and ready access to the internet. An evening offering introduced in 1998 was very successful and will be continued in 1999. Retention rates into second year following GEOS115 and the field unit GEOS224, have improved over the 3 year period.
Hands on experience: measuring dip and strike during GEOS224, Introduction to Field Geology.
- Minerals, Energy and the Environment (GEOS251) was redesigned by Simon Jackson in 1998 and will be offered as an internal unit in 1999, the first time in 5 years, as well in the current distance education mode. The unit now has its own web site. GEOS251 continues to be popular with students enrolled in Economics and Law and is the second general interest unit to be introduced or redesigned in GEMOC.
- Earth's Evolving Environment (GEOS272) has run successfully since its introduction in 1996 and has continued to attract a clientele from outside the geoscience pool.
- Volcanic Geology Fieldwork (GEOS373), a popular unit which examines modern magmatic environments of the Pacific Rim as keys to interpreting the ancient, is now offered as a new independent unit.
- In 1998 Simon Jackson started teaching in the units Aqueous Geochemistry (GEOS333) and Exploration and Environmental Geochemistry (GEOS377)
- in a cooperative arrangement with the Department of Chemistry, and will be joined in this by John Ridley in 1999.
- Links with Geophysics have been strengthened with the merging of the Geology and Geophysics areas, the arrival of Paul Morgan and the introduction of Global Earth Processes (GEOS436). This unit aims to integrate geophysical and petrological data to give realistic geological, thermal and seismic tomography images of the Earth.
- Our new named degrees, the Bachelor of Science in Geophysics, and the Bachelor of Technology in Exploration Geoscience (designed in close consultation with industry), continue to attract outstanding students with higher than average entry requirements. A new named degree, the Bachelor of Science in Environmental Geology, is planned for introduction in 2000.
- The Honours and Postgraduate unit Geochemical Applications and Techniques (GEOS437) continues to be popular and also serves as a SUCOGG Honours unit.
- More information is given below in the section on "Integration of Geophysics".
outcomes at Macquarie:
Increased visibility and teaching quality may be reflected in;
- Increased retention rates in core units (see graph). 300-level geophysics (118%) attracts students from other departments
- Increasing 100-level numbers in core unit (30% in 1998, 40% in 1999)
Geographic information systems in teaching
The last three years have seen a large step forward in the introduction of GIS into undergraduate teaching.
- In 1997 and 1998, laptop computers (through a grant of over $125,000 from Macquarie) and MapInfo software were purchased. Several teaching laboratories have been refurbished to facilitate use of the laptops and networked to allow teaching via the html environment.
- The laptops and GIS software have been used successfully in Introduction to Field Geology (GEOS224) during which the students use GPS data collected in the field to undertake a simple data entry and manipulation exercise. We are currently staging the introduction of GIS into GEOS115 via a mineral deposits exercise and Geological Structures (GEOS255) via the field excursion.
- The use of GIS databases and imaging is being phased in all units as an integral part of the teaching methodology to be consistent with industry practice.
- Micro-GIS (see Technology Development) is incorporated into the Geochemistry strand of Bachelor of Technology at third year and in relevant Honours courses and projects. ($33,000 for 1998 has been funded by Macquarie University to provide a microscope with digitised image capture to assist this purpose)
- Other teaching equipment funding for microscope replacements, powerbook portable computers, digital imaging systems and geophysical equipment were funded in 1998 (over $170,000) or awarded for expenditure in 1999 (approximately $230,000)
- The third year geological information systems unit GEOL3009 was further refined and increased student numbers make it the best attended of all 3rd year units in the Geology Department at ANU. Teaching continues to be centred on the science of remote sensing and image processing and the tools of GIS and database systems. Laboratory practical sessions involving acquisition of practical skills are the major component of the unit. A combination of conventional (lectures, hand-outs, assignments) and world wide web delivery modes is used to allow an auto-instructional self-paced programmed learning approach in the teaching of GIS and image processing. This combination of directed learning and "do-it-yourself" exercises, creates student enthusiasm and a high level of engagement and interest.
GEMOC offers scholarships for students with excellent undergraduate records who are carrying out GEMOC-related projects.
