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.

UFS teams up with Department of Agriculture and donates latest farming technology to Oppermans

Emerging and commercial farmers of the Oppermans Community in the Northern Cape will now be able to monitor the salinity levels on their farms effectively for the first time.

This is as a result of a donation of the latest technology that measures the salinity of soil – the EM38 system – which the University of the Free State (UFS) is donating to the community.

The unique project was launched by the Department of Soil, Crop and Climate Sciences at the UFS and the Department of Agriculture in the Free State during an information day held at Jacobsdal recently.

The day was attended by members of the Oppermans Community and representatives of the UFS as well as the Department of Agriculture. Mr Sugar Ramakarane, Head of the Department of Agriculture in the Free State, did the welcoming and several academics from the UFS held discussions about various topics related to the salinity levels in soil.

Since the establishment of the Oppermans Community emerging farmers are now for the first time able to accurately monitor the salinity levels on their farms as well as that of irrigation schemes of commercial farms in the area.

“In a region such as the Northern Cape it is very important that the salinity level of soil is monitored properly. As water is administered to crops, salts accumulate in the soil because the roots leave most of the salts in the soil when it transpires. When the salinity of soil increases, the osmotic potential thereof can also increase, which can seriously damage the water intake of crops and can create loss in yield and income,” said Prof. Leon van Rensburg from the Department of Soil, Crop and Climate Sciences at the UFS and leader of the Oppermans Project.

To assist the farming community of Oppermans to apply precision farming and to measure the salinity level of soil more accurately the latest technology that measures salinity in soil – the EM38 – will be donated to the community. Although the system is used throughout the world, the UFS is the only tertiary institution in the country that owns the latest version of this system.

“We are also training two persons from the Oppermans Community as technicians that will monitor the use of the system. The advantage of the donation of the system for the university is that we can gather data that can be used for research purposes by our Master’s and Doctoral students. We also want to see if water-table heights can be measured with this system,” said Prof. Van Rensburg.

According to him the system has several advantages for the community’s emerging farmers. “For the first time the salinity level of soil can now be measured accurately, salt maps can be drawn up, we can advise farmers about the corrections that need to be made and salinity management plans can be compiled,” he said.

The system is very accurate as it takes measurements every 200 mm while it is pulled by a four-wheel motorbike. The readings provide the distribution of salts up to a soil depth of 1 500 mm. “In the past the measuring of salinity levels was time-consuming and the cost thereof was R90 for one sample. The new system is more cost-effective,” stated Prof. Van Rensburg.

The instruments will be handed over to the African Spirit Group of the Oppermans Community, who will then become the owners. The service to farmers will then be managed by an operational group consisting of people from the Oppermans Community, a postgraduate student who can compile salinity maps and Prof. Van Rensburg, who will act as project leader and advisor.

The system will also be made available to farmers at the Riet River and Vaalharts Schemes.
