E-learning involves teaching using electronic resources and the internet. It allows students to learn at their own pace and convenience. Key benefits of e-learning include accommodating individual needs, providing unlimited access to updated content, quick delivery of lessons, reduced costs compared to traditional learning, and being environmentally friendly. E-learning can be synchronous, involving real-time online interaction, or asynchronous using prerecorded materials without real-time interaction.

2. E- LEARNING

3. DEFINITION
A learning system based on formalized teaching but
with the help of electronic resources is known as
E-learning. While teaching can be based in or out of the
classroom the use of computers and the internet forms the
major component of E-learning. E-learning ca be also be
termed as a network enabled transfer of skill and
knowledge and the delivery of education is made of a
large number of recipient at the same or different time.

4. THE MOST IMPORTANT OF
E-LEARNING
Today’s learners want relevant, mobile, self-paced,
and personalized content. This need is fulfilled with the
online mode of learning; here, students can learn at their
own comfort and requirement.
Online learning Accommodates Everyone’s Needs
The online method of learning is best suited for
everyone. This digital revolution has led to remarkable
changes in how the content is accessed, consumed,
discussed, and shared.

5. Lectures can be taken any number of times
Unlike classroom teaching with online learning you can
access the content an unlimited number of times. This is
especially required at the time of revision when preparing
for an exam.
 Offers access to updated content
Prime benefit of learning online is that it makes sure
that you are in synchronization with modern learners. This
enables the learner to access update content whenever they
want it.

6.  Quick Delivery of lessons
e-learning is a way to provide quick delivery of lesson.
As compared to traditional classroom teaching method, this
mode has relatively quick delivery cycles.
 Scalability
e-learning helps in creating and communicating new
training, policies, concepts, and ideas. Whether it is for
formal education or entertainment , e-learning is very quick
way of learning.
 Consistency
e-learning enables educators to get a higher degree of
coverage to communicate the message in a consistent way
for their target audience. This ensures that all learners
receive the same type of training with this learning mode.

7.  Reduced costs
E-learning is cost effective as compared to traditional
forms of learning. The reason for this price reduction is
because learning through this mode happen quickly and
easily. A lot of training time is reduced with respect to
trainees, travels, course materials and accommodation.
 Effectiveness
E-learning has a positive influence on an organizations
profitability. It makes it easy to grasp the content and digest
it.

8.  It results in improved scores on certification tests, or other
types of evaluation.
 Higher number of students who achieve ‘pass’ or ‘mastery’
level.
 Enhanced ability to learn and implement the new processes or
knowledge of the workplace.
 Help in retaining information for a longer time.
 Less impact on Environment
As e-learning is a paperless way of learning, it protects
the environment to a lot of extent. As per a study done
e-learning courses, it has been founded that distance – based
learning programs consumed around 90% less power and
generated 85% less amount of CO2 emissions as compared to
traditional campus –based educational course. With e-learning
there is no need to cut trees for obtaining paper. Thus,
elearning is a highly eco – friendly way of learning.

9. CHARACTERISTICS OF
E-LEARNING
1. The creation of virtual class room.
2. Provision of web – based learning materials.
3. Communication through email and electronic discussion
groups such as mailing lists and news groups.
4. Online listing: Internet which is a world wide collection
of computer networks has made available the tools
required for e-learning. The www, e-mail, mailing
list, news groups, chat room etc are some of these major
tools made available by internet.

10. MERITS OF E-LEARNING
 Learners learn at their own pace. They are not hound by
time or space e-learning is flexible.
 E-learning goes a long way to democratize education,
especially higher education.
 It encourages life long education.
 Learners are slowly made to be independent. Self
confidence and self respect will be developed as they
develop autonomy.
 Learners can search and find rich and varied sources of
information.

11.  E-learning provides greater participation of the learners in
the learning. Discussion and group activates make them
learn by effective interaction.
 A sense of cooperation and community life can be
developed.
 The learners are active and so learning is effective and
interesting.
 Unlike the traditional methods of education e-learning can
be done wherever the learner has a device capable of doing
so.

12. DEMERITS OF E-LEARNING
 Most of the online assessments are limited to questions
that are only objective in nature.
 There is also the problem of the extent of security of
online learning programs.
 The authenticity of a particular student’s work is also a
problem as online just about anyone can do a project
rather than the actual student itself.
 The assessments that are computer marked generally have
a tendency of being only knowledge based and not
necessarily practicality based.

13. TWO TYPES OF E-LEARNING
Synchronous learning
Asynchronous learning
 Synchronous learning
Synchronous learning involves online studies that
chat. This kind of learning can only happen online. By
being online, you can stay in touch with your teacher and
other student. It’s called Synchronous learning, because
the systems allows students to ask their teacher or fellow
students question in stately through instant messaging.

14. BENEFITS OF
SYNCHRONOUS LEARNING
 Students can ask questions in real time.
 Students feel a greater sense of community and connection
of their peers when they all learn together.
 Students become more engaged in their learning.
 Students feels a stronger sense of collaboration.

15. ASYNCHRONOUS LEARNING
On the other hand we have asynchronous learning.
This can be carried out online and offline. Asynchronous
learning involves course work via web, email, forums
students are not able to have instant messaging via this
online forum.
Asynchronous learning can be provided through
recorded lecture, power point slides or on their own time.

16. BENEFITS OF
ASYNCHRONOUS LEARNING
 Students can progress through the learning when they
want, where they want, at the pace they want, in the order
they want.
 Students have more time to reflect on what they learned.
 Shy students may feel more comfortable interacting with
their professor or peers when they have time to compose
throughout emails rather than feelings pressured to speak
up in alive conference.
 Students can participate in the same activities regardless
of time zone.
