This chapter introduces the motivations behind the current edited volume and provides a structure upon which subsequent chapters are organized. First, there is a brief chronology and snapshot of how teaching and instruction was affected by the Covid-19 pandemic at the post-secondary polytechnic level. The structure delineating the different disciplinary domains (e.g., geography, history, social sciences/studies, cross-disciplinary work) and the associated technologies and technological paradigms (e.g., digital humanities, educational technology) that were applied will be given a preliminary discourse. In addition to short summaries of the chapters, the salient issues, limitations in the field, as well as probable trends going forward will be highlighted for brief discussion.
