Background: Effective teaching of university chemistry in an online environment not only requires teachers to have specific discipline content knowledge; it also requires them to have knowledge and skills in technology-enhanced teaching practices. When transitioning from traditional face-to-face teaching into online contexts, teachers must learn new strategies and methods, along with a shift in their beliefs. Whilst online learning of chemistry is commonplace in many higher education institutions globally, the integration of computer and digital technologies in teaching chemistry in developing countries had been limited prior to the 2020 pandemic. Purpose: In this study, the experiences, perceptions, and teaching strategies of university chemistry teachers in the Philippines have been explored during the transition of their instruction to emergency remote teaching at two timepoints during the COVID-19 pandemic. Sample: Data were collected in the form of survey responses from 139 participants representing 35 universities and colleges across the nation. Results: No strong relationships were found between participants' experiences and their academic rank, length of service, or institution type, suggesting university chemistry teachers took similar approaches to quickly adopt and adapt available technologies to deliver the required curriculum. Since the Philippines continues to struggle to establish a robust infrastructure to promote online and technology-enhanced learning, participants had to devise pedagogies and practices that would allow accessible learning experiences for their students by curating online tools that would require minimal bandwidth and low internet data consumption. Using abductive methodology, the Community of Inquiry (CoI) framework was employed as a guide in interpreting university chemistry teachers' experiences and perceptions about their implementation of emergency remote teaching using online technologies. Whilst participants had limited prior experiences in employing online learning pedagogies, key elements of the CoI framework became apparent through the new technologies and practices implemented by university chemistry teachers which fostered teaching presence, cognitive presence, and social presence.
