This collection of academic proceedings explores the evolution of teacher education and professional development during the global shift toward emergency remote teaching caused by the COVID-19 pandemic. The research emphasizes that while schools have returned to face-to-face instruction, educators must integrate technological pedagogical knowledge and digital literacy gained during the crisis into future curricula. The authors highlight the critical roles of teacher agency and resilience, arguing that instructors should act as proactive change agents rather than returning to outdated methods. Specific case studies examine English language instruction, science, and social sciences, focusing on how informal digital learning and mobile applications can enhance student engagement. Ultimately, the sources advocate for a reimagined pedagogical framework that prepares both pre-service and in-service teachers to navigate future educational disruptions through sustainable digital integration.
