On 30 January 2020, the coronavirus disease 2019 (COVID-2019) has been officially declared a pandemic by the world health organization (WHO) as a public health emergency of international concern (PHEIC). Interpretation the developing epidemiology, diagnosis, treatment and transmission dynamics of the outbreak COVID-2019 by medical learners, future doctors, demands several consecutive steps, from formulating the correct research question to determining learning outcomes. Given the characteristics of learning medical topics, this study discusses the advantages of using concept maps (CMs) through action research process (ARP) as a core component of an undergraduate curriculum in medical education. Specifically, it presents evidence from an action research process aimed at assessing the impact of concept maps as a powerful tool for promoting meaningful learning on medical learners enrolled on the COVID-2019 module. The findings from the study suggested that an implementation of CMs through ARP have been effective, positive and powerful in meaningful learning for coronavirus disease 2019 (COVID-19). So the performance of learners improved from pre-test to post-test with the normalized gain (g) was 0.30, considered moderately effective. The outcomes of the study also concluded that CMs through ARP is one of the successful strategies that can be effectively, critically and meaningfully used to teach and learn coronavirus disease 2019 (COVID-19) in medical education at university of medicine Algiers, Algeria.
