This research aims to better understand how the COVID-19 pandemic has affected children's social, emotional, and moral development. Articles and related studies were gathered from the Education Resources Information Centre (ERIC), Scopus, and Science Direct databases. After a quality review following the PRISMA 2020 protocol, 16 articles were selected for a systematic literature review (SLR). The findings from this review were organized into four main themes: (1) the impact of technology and distance learning on children, (2) children's behavior and emotions, (3) the conditions of people around them, and (4) social support. It is suggested that future studies focus on the positive effects of COVID-19 on education.
