Data analytics as key to student success
Knowing who our students are and what their needs are is crucial information that forms the foundation of how institutions could help students succeed to cross the hurdles of student life.

Knowing how to help students succeed through higher education is one of the most pressing challenges currently confronting the system. Despite a significant change in the student population over the past few decades, we are only now beginning to understand who our students are and what their needs are. This crucial information forms the foundation of how institutions could help students succeed. Through two national-level projects funded by the Kresge Foundation, the University of the Free State (UFS) is contributing to the understanding of students and the development of data analytics. 

Siyaphumelela
  

The first project’s goal is to improve the institutional capacity of five higher education institutions to develop institutional research, with a specific focus on data analytics. The UFS was selected to be part of the Siyaphumelela Programme (meaning ‘we succeed’ in isiXhosa) that is sponsored by the Kresge Foundation, and supported by the NGO, the South African Institute for Distance Education (Saide). The project has enabled the UFS to strengthen capacity, collaboration, and to promote a culture of evidence. 

The project has also enabled the UFS to move from data reporting to a more analytical approach. This approach has enabled it to assess the impact of larger student success efforts and continuously improve the quality of these efforts. A focus on data analytics has helped the institution to reflect on its infrastructure and data management procedures. The development of dashboards has also allowed information to be shared with faculties. The UFS therefore sees a data analytical focus as critical to improving its effectiveness and efficiency.

The UFS is also playing a leading role nationally to develop academic advising that helps students align their studies, career, and life goals. Academic advising at the UFS includes the first-year experience module UFS101, online advising portals, and individual consulting sessions for students which focus on curriculum planning and success coaching. We have also proved a significant relationship between academic advice, student engagement and success.(Read Creating pathways for student success and Understanding students: A key to systemic success).


Student engagement

The second national project is focused on student engagement and has been run by the Centre for Teaching and Learning at the UFS for 10 years. To date, 20 universities have participated in at least one survey and the project also plays an important role in supporting the Siyaphumelela project goals. 

Engagement data has helped us to better align teaching and learning, and design environments that put student success and quality at the centre of institutional thinking. 

The culmination of findings from student engagement data in 2017 led to the publication of the book: Engaging students: Using evidence to promote student success, edited by Prof Francois Strydom, George Kuh, and Dr Sonja Loots, with contributions from various international and national experts in the higher education environment. This is the first comprehensive publication contextualising student engagement findings in the South African context for the benefit of advancing student success.

Both these projects are contributing to significant developments in the field of higher education and arguably more importantly, to help students succeed.

UFS venture cleans up acid mine drainage

South Africa is one of the most important mining countries in the world, beginning in the 1870s. Although the mining industry has been responsible for significant development and employment, it pollutes the environment and waters sources. Through the joint effort of a well-known mining company, the University of the Free State, and the Technology Innovation Agency (UFS/TIA) SAENSE Group, a new treatment for Acid Mine Drainage (AMD) has been developed.

The system treats the major contaminants found in acid mining wastewater effectively.  
 
The UFS remediation systems use a reservoir tank into which the AMD is pumped. The water then flows passively (without using energy) to the Barium Carbonate Dispersed Alkaline Substrate (BDAS) system. The metals and anions in the AMD react chemically with the barium carbonate and precipitate (form solids). The solids stay in the tank while the clean water is released.

The efficacy and applicability of the research was demonstrated on site in Belfast, Mpumalanga where the team constructed a pilot plant in July 2014. This patented technology has treated 1 814 400 litres of Acid Mine Drainage to date with an outflow water quality that satisfies the South African National Standards (SANS) 241:2006 & 2011 regulations for drinking water.   

Rohan Posthumus from the (UFS/TIA) SAENSE Group said: “At this stage, we do not recommend that the water should be used as drinking water, but certainly it can lower water usage in mines while finding application in dust suppression of washing processes. The team would like to complete a full characterisation of the final released water. There are currently no toxic by-products formed, and even very basic filtration can make the outflow drinking water.”

Prof Esta van Heerden’s research group from the Department of Microbial, Biochemical, and Food Biotechnology has been working on AMD research for some time, but the development of the BDAS system was started in 2013 by post-doctoral student, Dr Julio Castillo, and his junior researcher, Rohan Posthumus.

The data from the BDAS system have led to two publications in peer-reviewed journals as well as a registered patent.
