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.

A huge student turnout for NBT

More than 5 000 first-year students at the University of the Free State (UFS) recently wrote the National Benchmark Tests (NBT).

These tests are used to complement first-year students’ Grade 12 results and provide a profile of student competencies that the university can use to improve the quality of teaching and learning to enhance student success.

This was the first time that the UFS had made use of the NBTs, which were thoroughly piloted at several South African universities during 2009.

“A total of 5 449 students from the Main, South and Qwaqwa Campuses participated in this very ambitious testing process,” said Ms Merridy Wilson-Strydom from the Centre for Higher Education Studies and Development (CHESD) at the UFS.

“Altogether 7 687 test papers were completed. This is an excellent turn-out and highlights our students’ commitment to their studies.”

It was compulsory for all students (excluding those from the Faculty of Health Sciences) to write the Academic and Quantitative Literacy Test (AQL). Students from the Faculties of Economic and Management Sciences as well as Natural and Agricultural Sciences also wrote the Mathematics Tests.

“AQL targets students’ capacity to engage successfully with the demands of academic study in the medium of instruction, and the ability to manage situations or solve problems in a real context that is relevant to higher education study, using basic qualitative information that may be presented verbally, graphically, in tabular or symbolic form,” she explained.

“The Mathematics Test targets students’ ability with regard to mathematical concepts that are formally regarded as part of the school curriculum and tested in the Mathematics Examination Papers 1 and 2.”

The NBTs have been developed with inputs from over 300 academics from all the 23 universities in the country. They are available in English and Afrikaans.
Data integrity is quality-assured by the Assessment Systems Corporation in Michigan, USA, and further interrogated by the Education Testing Services in Princeton, New Jersey, USA.

The NBT results of UFS students will be available by the middle of March 2010. First-year students who do not perform at the required proficiency level in the academic literacy domain will be required to complete a language development module. This module is offered in both English and Afrikaans, depending on the chosen medium of instruction of the student.
