Michael von Maltitz
Prof Michael von Maltitz challenges current science education paradigms at the inaugural NAS Research Conference, urging a shift from grade-driven learning to fostering critical thinking, curiosity, and human intelligence in the era of AI and the Fourth Industrial Revolution.

In his keynote address at the inaugural NAS Research Conference on 1 July 2025, Prof Michael von Maltitz delivered a wide-ranging and compelling critique of the current state of science education. Speaking to an audience of researchers and academics, he challenged assumptions about learning, assessment, and the role of artificial intelligence (AI) in higher education – offering both caution and practical guidance.

Prof Von Maltitz – from the Department of Mathematical Statistics and Actuarial Science at the University of the Free State (UFS) – opened with an overview of the industrial revolutions leading up to the current Fourth Industrial Revolution, characterised by artificial intelligence, connectivity, and data-driven automation. He warned against remaining entrenched in this phase of development, arguing that AI, while powerful, is not truly intelligent. “AI … is … artificial,” he said. “It is based on brute-forcing very large numbers of very basic operations at blazing speeds, linking external inputs to stored information. And so, it’s not intelligent. It’s just strong.”

He cautioned that the unchecked use of AI – driven by efficiency, not understanding – risks entrenching systems that prioritise ease and profit over education and well-being. “Everything is profit-driven at the moment. Everything, and I mean … everything. Really. It is this greed that keeps us firmly stuck in the Fourth Industrial Revolution.”

This, he suggested, makes the vision of a Fifth Industrial Revolution both necessary and urgent. The next phase, he argued, should be one that centres on sustainability, equity, human-machine collaboration – and critically – the development of human intelligence and critical thinking. “There should be something here about ‘building human intelligence’ or ‘critical thinking’. This would truly make the Fifth Industrial Revolution about bettering humanity.”

 

When the measure becomes the mission

Central to his address was the idea of ‘broken proxies’ – the phenomenon where a measurement designed to approximate a goal becomes the goal itself, distorting the original purpose. He illustrated this concept using examples ranging from GDP and crime statistics to social media algorithms, before turning to science education. Here, grades and degrees, once indicators of knowledge and progress, have become ends in themselves.

“The only things that are important to students are grades and degrees, because the incentives are linked to grades and degrees, and so, obviously, all effort will go towards grades and degrees.”

Prof Von Maltitz reflected on his own academic journey, describing how he excelled at exams and accumulated qualifications, yet absorbed little meaningful knowledge in the process. “I played the grades game, and nothing stuck in long-term memory, as is the case with many of our students today,” he said. “Why? Well, there were merit bursaries, degrees, and awards up for offer, not for learning, but for performing well.”

This system, he argued, incentivises performance over understanding and leaves students vulnerable to shortcuts – particularly through generative AI. “Under the assumption that rewards are linked to grades and not education, if you offer a student an assessment method that can be gamed … it will be gamed.”

Referencing a recent MIT study, he warned of the cognitive toll of over-reliance on AI. “They showed that, over four months, the AI users’ brains became systematically less active, especially when asked at the end of the study to do a brain-only essay. They had lower brain function in every area. In four months, they had become significantly ‘dumber’ than their counterparts in the other arms of the study.”

 

Rebuilding curiosity and competence

Despite this sobering analysis, the address was not without optimism. Prof Von Maltitz urged delegates to reimagine education by shifting away from content-heavy teaching and rigid assessment structures. He called for a renewed focus on curiosity, conscious incompetence, and lifelong learning. “Are our students able to self-assess, identify weaknesses and gaps in their knowledge bases, seek answers, and build their own learning paths? Are they humble enough to say, ‘I don’t know’, and curious enough to go and find the answers?”

To support this vision, he proposed four practical steps: redefining teaching goals, distilling module content to its essentials, focusing on graduate attributes such as critical thinking and communication, and reassessing how learning is measured. He encouraged alternatives to traditional exams, including portfolios, interviews, peer assessment, and real-world problem solving.

“We don’t have to pretend to teach students everything in a particular field – but rather we show them what is out there to be learned,” he said.

“Education should not be about teaching everything,” he concluded, “but about showing students what can be known, how to learn, and where to go next.”

King Moshoeshoe comes alive on national television
2004-11-02

Honourable Bethuel Pakalitha Mosisili, Prime Minister of Lesotho, and his wife; King Letsie III of Lesotho and Dr Ezekiel Moraka, Vice-Rector: Student Affairs at the UFS during the première of the film at the Royal Palace in Lesotho

The ground-breaking documentary film on the life and legacy of King Moshoeshoe, the founder of the Basotho nation, will come alive on Thursday 4 November 2004 when it is screened on SABC2 at 21:00

The film, called Moshoeshoe: The Renaissance King, forms part of a larger project by the University of the Free State (UFS) to honour the Moshoeshoe legacy of nation-building and reconciliation and to explore his role as a model of African leadership. It was produced by the well-known journalist Mr Max du Preez and commissioned by the UFS as part of its centenary celebrations.

The SABC2 screening was preceded by a première in Bloemfontein last month, and was attended by provincial political leaders.

This past weekend there was a première at the Royal Palace in Lesotho, which was attended by King Letsie III, the prime minister, the chief justice, judges, the president of the senate, cabinet ministers and directors-general.

“Through this documentary film the UFS commits itself to developing a shared appreciation of the history of this country and to the establishment of the Free State Province as a model of reconciliation and nation-building. King Moshoeshoe is also a strong common element, and binding factor, in the relationship between South Africa/the Free State, and its neighbour, Lesotho,” said Prof Frederick Fourie, Rector and Vice-Chancellor of the UFS.

“Not all people in South Africa know the history of Moshoeshoe. Many Basotho – but not all – are well versed in the history of Moshoeshoe, and his name is honoured in many a street, town and township. Many white people know little of him, or have a very constrained or even biased view of his role and legacy. In Africa and the world, he is much less known than, for instance, Shaka,” said Prof Fourie.

“King Moshoeshoe did a remarkable thing in forging a new nation out of a fragmented society. He also created a remarkable spirit of reconciliation and a remarkable spirit of leadership,” said Prof Fourie.

According to Prof Fourie we already benefit from his legacy: the people of the Free State share a tradition of moderation and reconciliation rather than one of aggression and domination. “For the UFS this is also part of real transformation – of creating a new unity amidst our diversity,” said Prof Fourie.

“We also find in the legacy of King Moshoeshoe the possibility of a “founding philosophy”, or “defining philosophy”, for the African renaissance. To develop this philosophy, we must gain a deeper understanding of what really happened there, of his role, of his leadership. Therefore the UFS will encourage and support further research into the history, politics and sociology of the Moshoeshoe period, including his leadership style,” said Prof Fourie.
