In this sense, the e-learning approaches can combine
different types of e-learning components, including [11]: e-learning content (contain simple learning resources; interactive
e-lessons; electronic simulations; and job aids); e-tutoring, e-coaching, e-mentoring (services which provide human and
social dimensions can be offered to students to support them
through the learning experience);collaborative learning (range
from discussions and knowledge-sharing to working together
on a common project); and virtual classroom (is the
instructional method most similar to traditional classroom
training, as it is led completely by an teacher).
