This book aims to provide sustainable solutions for better understanding and management of online education in different parts of the world. In this context, it explores the attitudes and perceptions of stakeholders, such as students, faculty, and other actors on issues related to online education. In particular, it examines the challenges they have faced over the years when online courses were introduced due to the COVID-19 pandemic. A model is proposed that includes five variables: specific communication issues in online education, the ability of professors to offer online courses, the quality of online education, students perceived stress during online education, and the technical requirements of online education. The book will be of interest to anyone concerned with the new and future ways of teaching and learning.
