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.”

Statement by Judge Faan Hancke, Chairperson of the Council of the University of the Free State (UFS)
2008-03-08

The Council of the University of the Free State today (Friday, 7 March 2008) unanimously condemned the offensive and racist Reitz video in the strongest possible terms.

Council further labeled the video as an insult to women, to older persons and to poor working people who are defenseless and vulnerable and expressed its disgust at the action of the students concerned.

Council also apologised unreservedly and sincerely to the five UFS employees who were shown in the video and offered all emotional and counselling assistance necessary as well as in the current criminal matter under way or possible civil action they may undertake.

At the same time the university must also provide counseling to current first year students of Reitz who were not present at the time of the filming of the video.

Council also mandated the management, in addition to the other disciplinary steps under way, to consider the possibility of closure and of conversion of Reitz into a beacon of transformation, hope and liberation (either as a residence or in some other form).

This must take place in accordance with due process of the law to give residents and other stakeholders reasonable opportunity to make submissions so that all relevant considerations can be taken into account.

The Council expressed its full confidence in the management and supported the steps taken by management thus far under trying circumstances concerning transformation, residence integration, the Reitz video and the vandalism of the campus.

It reaffirmed the decision taken in June 2007 to increase diversity in student residences and recommitted the UFS to implement the policy.

The Council condemns all forms of racism and committed itself to eradicate racism and racial prejudice in any form and from any quarter on the UFS campus.

The meeting also approved the appointment of an external expert agency to assist the university in:

  • understanding and identifying the current challenges relating to the implementation of the integration policy 
  • supporting the university management and making recommendations on how to enhance the process of implementation

The intention is to provide additional capacity to the management in order to accelerate the transformation and integration process.

It called on management to take firm action against any staff or student who violates the law, is involved in threats, racism, disruptions, intimidation and vandalism and condemned these actions in the strongest possible terms.

The Council reassured all staff, students, parents and other stakeholders that firm action will be taken against persons who are guilty of disorderly conduct, intimidation, disruption or similar actions with the full force of the law.

The management was requested to maintain law and order so as to create a conducive environment in which academic excellence can be furthered. The Council appreciates the steps that have been taken in this regard.

The Council supported a management initiative to investigate the fundamental issues underlying many of the current problems in residences, including:

  • residence culture, including initiation, as well as race, racialism and racism
  • alcohol and drug abuse role,
  • place, organisation and management of residences constitution of student structures
  • and the role of political parties in student politics and structures
  • the physical structure of residences as part of a campus accommodation strategy

The Council agreed that social cohesion and racial tolerance will be highlighted as a strong theme in the academic cluster initiatives of the UFS and that management should find additional ways to strengthen existing programmes regarding diversity on the campus among all staff and students.

The Council called on all stakeholders to honour the high values of the Constitution of the country, to maintain these values and to further them in an orderly and peaceful environment.
