Read MoreMathematics during the pandemic
Editor's Note
WISAARKHU Volume 2 aims to provide a diversity, not necessarily a jointly exhaustive collection, of perspectives of Mathematics during the COVID-19 pandemic.
During this time of the COVID-19 pandemic with many uncertainties, the transition to online learning, teaching, and assessment requires extraordinary efforts of all learners, all students, all teachers, all lecturers, and all parents/guardians. This transition may not be easy; it may not be perfect. However, there may be a unique opportunity to rethink our approaches to teaching and learning and assessment of Mathematics for the benefit of all. Much may be accomplished through working together and having realistic expectations of each other, including ourselves.
Within this context, the second volume of WISAARKHU includes contributions on 4 main subthemes, namely, experiences of the pandemic within and beyond mathematics, mathematical modelling of the pandemic, online offering of mathematics during the pandemic, and protecting mental health during the pandemic.
It is a magazine for inspiring with ideas and successful approaches, for creating awareness, for sharing experiences, for communicating, for connecting, and for reflecting.
It is not a research journal. It does not purport to endorse any particular opinion or approach to the learning and teaching of mathematics. Its readership is intended for all from across the globe with an interest in mathematics.
Each perspective expressed in the content of WISAARKHU is that of the author. It does not purport to reflect the opinions of the editor or Stellenbosch University or the affiliations of the authors.
No matter your interest in or experience of Mathematics, I hope you will read this magazine acknowledging the intention with which it has been written.
