<p>One major challenge researchers have faced during the disruptions resulting from the Covid-19 pandemic is how to adapt to the global virus and, at the same time, make good progress in their research pursuits. Also, many international researchers have suspended ongoing research in developing countries due to inadequate online facilities in these countries. This article identifies innovative methodologies that can be employed to carry out mixed-method research in a non-technologically advanced country and reflects on the benefits and limitations of carrying out such rigorous research during difficult times. The mixed-method research design reported here combines tests and open-ended reasons for procedures to explore the impacts of two pedagogical practices on students' mathematical understanding. In particular, the methodological framework leverages the aims of the research, the theoretical background, standard ethical practice, and Covid-19 safety precautions. This article contributes to the methodological approaches for carrying out mixed-method research during unprecedented times.</p>
