This article reports findings from a mixed-method study investigating parents' perspectives and experiences in navigating their children's online learning during the COVID-19 pandemic. The study involved surveys of parents (n = 775) and interviews (n = 32) conducted in eight primary schools in Hong Kong. Statistical analyses revealed that parents' perceptions of online learning (PPOL) were positively affected by their self-efficacy in providing online learning support, their expectations for parent-teacher communication, and their satisfaction with schools' support. Conversely, increased levels of parental engagement and stress, and the need for regular school updates negatively affected PPOL. Qualitative findings showed that parents' perspectives were influenced by experiences tied to their normative role expectations and their perceptions of teachers and schools, which subsequently shaped their emotional responses to online learning. These findings offer nuanced insights for developing policies and practices aimed at better supporting parents' engagement in the digital era.
