Query: Does transitioning to online classes mid-semester affect conceptual
  understanding?   The Force Concept Inventory (FCI) can be used as an assessment tool to
measure conceptual gains in a cohort of students. The FCI uses a
conceptions/"misconceptions" lens rather than a context dependent perspective,
such as "knowledge-in-pieces". In this study it was given to first year
students ($N=256$ students) pre- and post-mechanics lectures, at the University
of Johannesburg. From these results we examine the effect of switching
mid-semester from traditional classes to online classes, as imposed by the
COVID-19 lockdown in South Africa. Overall results indicate no appreciable
difference of gain, when bench-marked against previous studies using this
assessment tool. When compared with $2019$ grades, the $2020$ semester grades
do not appear to be greatly affected. Furthermore, statistical analyses also
indicate a gender difference in mean gains in favour of females at the $95\%$
significance level (for paired data, $N=48$).
