- Subject Assessment Guidelines for Physical Sciences
The Physical Sciences MasterClass Series of videos was produced to highlight, clarify and refine the most important concepts as described in the Subject Assessment Guidelines (SAGs) for Physical Sciences.
An effort was made to address each of the concepts referred to in the SAGs for both Physics and Chemistry. This was done by discussing common mistakes and pitfalls for topics with which students will be more familiar by now, as these were covered as part of the Grade 11 year. Other topics are discussed in depth and focus is placed on revising and clarifying concepts with which students traditionally encounter difficulties or are lacking in experience/practice.
In each of the videos in the Series, exam-style questions or questions adapted from past papers are discussed with the aim of providing the student with a blueprint to answer these questions. Special care was taken when discussing multi-calculation, multiple choice questions and explanation questions to explain how the student can get to the answer in depth.
Students are encouraged to attempt the questions themselves before watching the explanation. A student who watches this MasterClass Series attentively and who takes an active learning approach to the explanations given, by working through other past papers, will be thoroughly prepared for the examinations.
Susan Wilson completed her Bachelor of Computational Physics, and her Honours Degree in Physics at the University of Kwa-Zulu Natal. She then entered the NASSP (National Astrophysics and Space Science Programme) at UCT, before completing her MSc in Space Science at North-West University. Finally, she completed her Doctorate in astrophysics at the University of Kwa-Zulu Natal; her thesis explored how the relationships between various properties of galaxy clusters have evolved over time. During her studies, she also assisted with tutoring younger students and worked as an assistant during first-year Physics practicals.
After completing her PhD, Susan realised her passion lay more with teaching and education; she, therefore, completed her PGCE (Postgraduate Certificate in Education) through UNISA. She pursued a teaching job at Epworth High School in Kwa-Zulu Natal, where she taught Physical Sciences, Natural Sciences, Mathematics and Applied Mathematics. In 2021, she made the move to Redhill and began teaching Physics for the International Baccalaureate program as well as IEB Physical Sciences.
