The teaching project of Drs Matthew Huber and Martin Clark on utilising aerial photography and 3D models increased student engagement in Geology field studies.

The goal of an educator, as seen by Dr Matthew Huber and Dr Martin Clark, is to try and improve the understanding of students. They believe that by combining technological and geological elements within the framework of games, students not only learn but also enjoy the process.

Dr Huber and Dr Clark are from the Department of Geology at the University of the Free State (UFS).

By bringing innovative methods into their teaching processes, they have successfully enhanced student engagement and learning in Geology field studies.

Limited innovation equals limited engagement

As part of the third-year Economic Geology and Exploration Geology courses, students were taken on a field trip to the Vredefort impact structure and an active gold mine. At the Vredefort structure, they were able to view the rock types mined for gold – which are exposed on the surface – to prepare them to identify the rocks when going underground. They also visited an open-pit quarry that was mined for granite dimension stone in the 1950s.  

Fot the visit to the quarry, the students were given ‘traditional’ assignments in advance to make measurements, sketch relevant features, and write down observations. 

“We found that they were not particularly engaged in what they were doing; it was simply an assignment that was separated from any deeper meaning in their minds,” explains Dr Huber.

The status quo of student engagement was about to change. Dr Huber and Dr Clark put their heads together and had a long discussion on how they could improve the exercise. 

Innovative methods equal increase in engagement

“We realised that we could change the focus of the exercise entirely by framing it as a game. When the exercise started, the students were divided into ‘companies’, and then told that they had to pick blocks with particular features to extract from the quarry. They were given parameters concerning how much various aspects of the activity would cost and were then told to make as much money as possible. We did not give them any particular measurements but provided them with all the tools they needed.”

“This had a transformative effect on the students – instead of being bored with the quarry exercise, they were begging for more time to look at the rocks, coming up with innovative solutions on their own,” says Dr Huber.

He believes this is what student engagement means. “Even though we did not assign any particular measurements for the students to do, most of them were diligently making measurements and even arguing with one another about the best way to pick out blocks,” he adds.

To evaluate the students, Dr Clark brought in a technological aspect to the exercise. He made a 3D model of the quarry while the game was in progress, which was used at the end of the task. 

“The students showed us the blocks that they had picked out on the digital 3D model, which we could rapidly evaluate. In addition, they had an opportunity to look at the problem from a different perspective, resulting in ‘last minute’ innovative solutions. The exposure to this type of digital interaction on a traditional geological excursion has increased the ‘cool’ factor for the students and subjected them to new ways of problem-solving – similar to what they can expect later in their careers,” explains Dr Clark.


Innovative methods equal more possibilities

Both Drs Clark and Huber agree that the feedback they received from the students was amazing. “They did not want the assignment to end, and unanimously petitioned us for more time in the quarry, driven by their desire to make the best decisions for their groups. This level of passion from students has never been experienced by either instructor on any other field course,” adds Dr Huber. 

Although games are not a new concept in education, the two academics say they are not aware of any other institution that has attempted to digitally recreate a site for students in real time with this type of game. Drs Clark and Huber also wrote an academic article that is currently in revision for the Journal of Geoscience Education, titled, ‘Using gamification and fourth industrial revolution components to enhance student engagement in traditional field exercises for economic geology students’.

“The other wonderful aspect of this type of exercise is that we now have a digital archive of the site, and we can use that in both student training and our research. In times like now, where it is difficult to travel to the field, this type of model of geological exposures is invaluable,” says Dr Clark. 

They both believe the attitude and philosophy of the educators are very important in terms of student training. Regardless of whether face-to-face or online teaching is offered, there can be a good response to games used in the classroom.

“The more learning scenarios we can expose students to in fun, enjoyable, and innovative ways, the more likely we will spark lifelong passions that they can take with them through their careers. Our goal is not only to create good students but give them the tools to become thought leaders for the next generation of learners,” says Dr Clark.

Researcher wins prize for her work to reduce environmental pollution

Josepha Zielke, a PhD student at the Institute for Groundwater Studies at the University of the Free State (UFS), received the prize for the best student presentation at the International Mine Water Association (IMWA) symposium in Leipzig, Germany, this year. Her paper was titled Fine Ash Leaching in Tailings Dams – An Impact on the Underlying Aquifers?
 
Zielke said: “It is an honour to receive this prize as a student. IMWA is a big association which allows you to establish a network with other scientists, to exchange opinions and ideas and to gain new inspiration for your own work. It was exciting and informative to hear about the research conducted around the world and to meet the researchers themselves.”
 
Born in Germany, Zielke always wanted to study overseas. During an exchange year in Grade 11, she visited South Africa. When she had to make a decision about in which country to complete her studies, South Africa was first choice as she was familiar with the people and the country.
 
Zielke joins leading institute on groundwater research in the country
She completed her BSc Hons in Geology at the Nelson Mandela Metropolitan University. After working for a year in exploration, she decided to focus her studies on water-related problems which  has been a growing issue, not only in South Africa, but in many places around the world. Zielke heard that the UFS Institute for Groundwater Studies was the leading institute on groundwater research in the country, and decided to join the university.
 
After completing her MSc research, An analysis of the geochemical weathering profile within a fine ash tailings dam, Mpumalanga, South Africa, Zielke started the research for her PhD project on groundwater pollution along a fault system in Mpumalanga.
 
Research adding value to the environment by reducing pollution
She explains the focus of her research: “Several production plants and mine waste facilities are located on or near these geological structures which could be a possible cause of ground and surface water pollution. With the aid of geophysical ground surveys (using electromagnetics and electrical resistivity tomography), aquifer and tracer tests, we are trying to determine where the pollution is coming from, how far it has been distributed and to model the potential risks.
 
“This research will add value to the environment by preventing or at least reducing pollution leaking into the environment. Industrial sites always have a negative footprint on the environment but at least we try and contain it by finding the cause of ground and surface water pollution. Thereafter we try and solve the pollution problem or at least mitigate the damage to prevent the spreading of ground and surface water pollution in the area.”
