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.”

State of our campuses: Impact of non-completion of the 2016 academic year on UFS students
2016-10-08

Dear Parents/Guardians and Students,

Impact of non-completion of the 2016 academic year

The University of the Free State (UFS) reiterates its support and commitment to the cause of free higher education. We have stated our position in all the available spaces. We want to work with UFS students to put pressure on the government to commit itself to accept the many suggestions put forward to make free education possible within a negotiated timeframe.

We are also seriously committed to our responsibility of providing education to all students enrolled at the university. We are doing our outmost to ensure that we can resume academic activities next week.

Description: " Academic non-completion 2016 Tags: " Academic non-completion 2016

We want to bring to your attention what will happen to individual students if the UFS cannot resume classes fully on Monday 10 October 2016.

Currently we have extended the academic year by one week. Some faculties are working on Saturdays and Sundays, starting earlier and finishing later to complete the material that needs to be taught and the practical work that students need to do to be able to write exams.

In the three biggest faculties at the university: Education, the Humanities, and Natural Sciences, this is what will happen:

  • Education will fail to graduate 1 193 students
  • Humanities will fail to graduate 1 125 students
  • Natural and Agricultural Sciences will fail to graduate 1 390 students

In the professional faculties: Economic and Management Sciences, Health Sciences, and Law, this will happen:

  • Economic and Management Sciences will fail to graduate 997 students
  • Health Sciences will fail to graduate 633 students
  • Law will fail to graduate 619 students

In total, approximately 6 000 students will not receive complete transcripts of their degrees and the certificates for their qualifications.

The university currently has 3 238 students on NSFAS bursaries. None of these students will be able to apply for bursaries for the lost year. They will be regarded as having failed or not completed their courses. They will not only miss this year, but the opportunity of studying in the future.

These students come from families to which their success in higher education was supposed to mean a change in the future of the entire family. Some parents/guardians hold more than one job to be able to pay tuition fees.

In not allowing the year to continue and students to finish, we are throwing away the efforts that entire families of poor people have made for four or five years to put their children through university. The promise of free education for future generations means nothing to these families who are poor in the present.

In terms of the academic calendar, it is a false argument to say that universities will be able to enrol first-years, because what 2016 students will miss, is the second semester.

We do not have the capacity to teach double the number of students in the second semester. This also misses the point that those students who were completing modules in order to graduate, will waste an entire year (assuming they have funding) to complete their degrees. This argument does not see the knock-on effect that students, not promoting in modules from first to second and second to third year, etc., will have. Finally, this also misses the point of what will happen to students who have to repeat first-semester modules.

In terms of academic staff, students are discounting the willingness of academic staff to teach double or to have the academic year extended by approximately six weeks between teaching and examinations. The same can be said for all the administrative and support staff required for running the university.

In our case, all the students in the University Preparation Programme (UPP) on the South Campus in Bloemfontein will be stuck without being able to move into mainstream modules, preventing a new intake of UPP students for 2017. These are the poorest and most disadvantaged students at the UFS.

It is absolutely necessary to find a means of protest and political action that will not jeopardise the future of current students and the country’s desperate need for critical skills.  The interdict against violent protest secured by the UFS is still in force. The police will intervene if the interdict is not respected and the UFS will have no control over police actions.

We trust that parents/guardians and students understand the implications of the situation.

Kind regards,

Prof Nicky Morgan
Acting Rector
University of the Free State
