Dr Ocaya
Dr Richard Ocaya’s research addresses the skills development and transfer millennium goal of many governments globally.

With the Fourth Industrial Revolution becoming a reality, Dr Richard Ocaya’s research is receptive to the fact that Africa and the world need to re-imagine their research. His research focuses on electronic instrumentation design for scientific measurements, computational physics on atomic nano-atomic structures, and semiconducting organic compounds materials built on silicon to realise Schottky devices.

Software developer 
“I develop most of the instrumentation that I apply in my research – both software and hardware,” said Dr Ocaya, a Physics Lecturer and Programme Director: Physics and Chemistry on the UFS Qwaqwa Campus.

“I am active in scientific computing through the computing cluster and software development, mathematical physics for material science modelling, and embedded instrumentation design using microprocessors. I also have deep interest in radio and data telemetry, in which I hold a South African patent issued in 2013. My present international collaborations are with like-minded researchers in similar fields in Saudi Arabia, Turkey, Japan, Egypt, South Korea, and the United States,” he added.

How does his research talk to the real world?
“The driving principle of all areas of my research has always been to deploy cutting-edge research to actual, real-world applications for the immediate betterment of Africans. The areas of my research align closely with the millennium goals of many governments globally, including the Republic of South Africa. These goals pertain to skills development and transfer that position us to better address the challenges of energy, water, and other priorities.”

Dr Ocaya is currently co-promoting a PhD student, having previously supervised one PhD, two MSc, and more than twenty honours students. He is a self-taught electronics and computer programmer, whose curiosity led him to question ‘the voices and music coming from a box; a radio’. “In my quest to satisfy my curiosity, I collected many discarded devices, took them apart, and tried so many circuits, only to have them fail because the theory was lacking. After thousands of failed projects and with me barely thirteen and in lower secondary school, my first ever project actually worked,” he said.

NRF-rating
He is the author of the book Introduction to Control Systems Analysis using Point Symmetries: An application of Lie Symmetries, which is available in all major bookstores such as Amazon, in both print and e-book format. He is a C3 NRF-rated researcher whose work makes a pioneering contribution to the new and growing field of phononics, an independent field of the now established photonics.

“This field will someday lead to improved energy-storage devices and faster processors due to more efficient heat removal from nanodevices,” he concludes.

Work clouds and rhizomatic learning – Prof Johannes Cronjé teaches through technology in inaugural lecture
2014-09-29

Prof Johannes Cronjé 

Prof Johannes Cronjé has been appointed as visiting professor in the Faculty of Natural and Agricultural Sciences in collaboration with the Centre for Teaching and Learning. The driving force behind his appointment is to develop young and upcoming scholars in the field of online and blended learning at our university.The title of Prof Cronjé’s inaugural lecture, ‘Tablets, Painkillers or Snake Oil – a Remedy for Education?’ suggested a compelling event. Prof Cronjé did not disappoint.

“We live in a world where we carry more information in our pockets than in our entire head,” Prof Cronjé remarked. Interesting fact: an iPhone 4 has 16 million times more processing power than the Apollo 11 – the spacecraft that put the first man on the moon.

If students carry this much processing power in their hands, what should we be teaching students? Prof Cronjé asked. “I believe the answer to that is: we should be teaching them to teach themselves.”

Presenting his inaugural lecture in the same way as he would to his students, Prof Cronjé had the entire audience within minutes vigorously participating in the event.

Prof Cronjé advocates a process called rhizomatic learning. Knowledge, he explained, grows in a similar way to rhizomes’ roots – inseparably connected and seemingly without beginning or end. “Learning is a social aspect: people learn from one another.”

Making use of freely-available online applications, Prof Cronjé demonstrated the power of technology in the classroom. “My objective is to use technology to make people enthusiastic and motivated about the learning process.” Using their smartphones, tablets and laptops, the audience could effortlessly participate through connecting to each other by means of a virtual work cloud. “Knowledge is being created in the room as it happens,” Prof Cronjé explained, “motivating you to participate in this learning experience.”

“There are three things you need for group work to be successful: a mutual goal, individual responsibility and positive interdependence. Then it is real cooperative learning,” Prof Cronjé concluded.
