According to Statista.com,  "Technology has changed the possibilities within teaching and learning. Classes, which prior to the digital era were restricted to lectures, talks, and physical objects, no longer have to be designed in that manner. Teachers and students now have a digital toolbox – ranging from engaging devices to teach the students to online courses and digital textbooks. Digital education is the term used to refer to all online educational practices. Projections show the e-learning market worldwide is forecast to surpass 243 billion U.S. dollars by 2022. In 2016, the self-paced e-learning product market amounted to 46.67 billion U.S. dollars and is projected to decrease to 33.5 billion U.S. dollars in 2021. A considerable share of faculty worldwide have shown a willingness to support less traditional and digital education models. About 65 percent of faculty supports the use of open educational resources (OERs) in teaching, and 63 percent showed support for the competency-based education system."
