E-learningE-Learning is a term referring broadly to technology-based learning, seems to focus

on Web-based delivery methods, but often used in broader context.

E-learning is the use of online technologies in learning and teaching:

•E-mail

• Websites

• Multimedia – webcams, video, audio, animation

• information from the Internet

• Discussion groups

• Chat software

• Bulletin boards

- Course Management Systems (CMS)

- Enterprise Learning Management Systems

(ELMS)

- Learning Content Management Systems (LCMS)

• Software tools:

• Authoring Tools

• Real-time Virtual Classrooms

• Learning Management Systems (LMS):

• Virtual instructors • Online Tests

• Newsgroups

• Teleconferencing & videoconferencing • Shared

whiteboards

• Web forums

• Computer files

Advantages of e-learning

• Lower costs

• Learn when you need it (Just-In-Time)

• Effective use of time

• Learning options are not constrained by learners geographic location

• Effective for certain types of learners (shy, reflective, language challenged, those that need

more time)

• Instruction can be more customized and flexible (especially CBT)

• Side benefits of learning new technologies and technical skills

• Learning can be fit into learners busy schedule

• Learner-focused

• Etc.

Critical analysis

• Study of 40 Global companies - unless forced, the majority of workers (68%) would not sign up for voluntary online courses (by Forrester Group).

• Even when online courses were compulsory, over 30% refused to sign up.

• Those who do sign up for a course, between 50% and 80% never finish the

course.

Crisis in e-learning

Why?

• Focus on new technology, not on

instructional design

• Speed to market

• Boredom

• Lack of understanding of learning

and teaching

• Lack of understanding of the unique

teaching advantages of electronic

media

ConclusionsITS is not a new term, but the problem is still actual. In addition to the continuing work on

ITS, one important research issue is to use methodologies of AI as a theoretical base of the

ITS, as well as learning theory, instructional design, instructional strategies, pedagogy, and

teaching methods. This connection can open new perspectives in e-learning research area.

Seeing no really usable practical results, ITS is still perceived by many as a technology of

the future, but the rapid growth of learning software and artificial intelligence is making it a

viable option.
