INTRODUCTION
E-learning is the use of electronic media
and information and communication technologies in education. Elearning is broadly inclusive of all forms of educational technology in
teaching and learning. E-learning is inclusive of, and is broadly
synonymous with multimedia learning, technology-enhanced learning,
computer-based instruction, computer managed instruction, computerbased training, computer assisted instruction or computer aided
instruction, internet- based training, web-based training, online
education, virtual learning environment, m learning, and digital
educational collaboration. These alternative names emphasize a
particular aspect, component of delivery method.
E-learning include numerous types of
multimedia that deliver text, audio, images, animation, and streaming
videos, and include technology applications and processes such as audio
or video tape, satellite TV, CD-ROM, and computer-based learning, as
well as intranet/extranet and web-based learning on either local network
or the Internet in networked learning, underlay many E-learning
processes. E-learning can occur in or out of the classroom. It can be selfpaced; asynchronous learning or it may be instructor-led, synchronous
learning. E-learning is suited to distinct learning and flexible learning,
but it can be also used in conjunction with face-to-face learning, in
which case the term blended learning is commonly used.

E-LEARNING
E-learning in learning and education refers to the
use of modern technology, such as computers, digital technology,
networked digital devices and associated software and courseware.
There are several aspects to describing the intellectual and technical
development of e-learning, which can be categorized into discrete areas.
1. e-learning as an educational approach or tool that supports
traditional subjects
2. e-learning as a technological medium that assists in the
communication of knowledge, and its development and
exchange
3. e-learning itself as an educational subjects, such courses
may be called Computer Studies or Information and
communication technology
4. e-learning administrative tools such as education
management information system
EDUCATIONAL APPROACH
The extent to which e-learning assists or replaces
other learning and teaching approaches is variable, ranging on a
continuum from none to fully online distance learning. A variety of
descriptive terms have been employed to categorize the extent to which
technology is used. Distributed learning may describe either the elearning component of a hybrid approach, or fully online distance
learning environments. Another scheme described the level of
technological support as web enhanced, web supplemented and web
dependent.
CONTENT OF E-LEARNING
Content is a core component of e-learning and includes
issues such as pedagogy and learning object re-use.
PEDAGOGICAL ELEMENTS
Pedagogical elements are defined as structures or units
of educational content that is to be delivered. These units are
independent of format, meaning that although the unit may delivered in
various ways, the pedagogical structures themselves are not the text
book, web page, video conference, Podcast, lesson assignment, multiple
choice question, quiz, discussion group or a case study, of which are
possible methods of delivery.
PEDAGOGICAL APPROCHES
Various pedagogical perspectives or learning theories
may be considered in designing and interacting with e-learning
programs. E-learning theory examines these approaches, including
social-constructivist, one application of which was One Laptop per
Child. Self regulated learning refers to several concept that play major
roles in e-learning. Learning courses should provide opportunities to
practice these strategies and skills. Self-regulation and structured
supervision both enhance e-learning.
E-LEARNING IN MATHEMATICS
Making mathematically accurate and pedagogically
skillful diagrams. One problem faced by mathematics teachers at all
levels is how to make clear and accurate diagrams that makes the
essential ideas plain to learners, and how to do so in way that are
manipulable for mathematical reasoning. Doing this by hand is often no
easy task, whether the sketch is of an ellipsoid in calculus, or sixteenths
of a rectangle in fifth grade.
Mathematical accuracy is one of dimensions of the challenges; featuring
is a second – that is, making the instructionally key features visible to
learners. In addition, instructors must manage these challenges fluently,
using class time effectively. Important is the capacity to produce
carefully-scaled diagrams, with the capacity for color or shading, and to
be able to move elements of a diagram. Its use must be fast and flexible,
helpful both for carefully designed lectures and for improvisation on the
fly, in response to a student’s question. Such software or tools can
provide significant support for the use of diagrams in class; by both
students and instructors. Making such software accessible to students
increases their capacity for individual explorations and preparation for
contributions in class. Software tools to support the making of diagrams
can create problems too. Technology continues to transform all aspect of
our lives and works. It is already difficult to imagine how we once
functioned without email and the web. We are still at the early stage of
trying to understand and design the best uses of technology for
mathematics instruction.
APPLICATIONS
1.Preschool
Various forms of electronic media are a feature of
preschool life. Although parents report a positive experience, the impact
of such use has not been systematically assessed. Parameters, such as
age appropriateness, coherence with sought-after values, and concurrent
entertainment and educational aspects, have been suggested for choosing
media.
2.k-12
E-learning is utilized by public k-12 schools in the
United States as well as private schools. Some e-learning environment
take place in a traditional classroom, others allow students to attend
classes from home or other locations. There are several states that are
utilizing virtual school platforms for e-learning across the country that
continue to increase
3.Higher education
Enrollments for fully online learning increased by an
average of 12-14 percent annually between 2004 and 2009, compared
with an average of approximately 2 percent increase per year in
enrollment overall. The Sloan report, based on a poll of academic
leaders, indicated that students are as satisfied with on-line classes as
with traditional ones.
4.Corporate and professional
E-learning has now been adopted and used by various
companies to inform and educate both their employees and
customers. Compliance has also been a big field of growth
with banks using it to keep their staff’s CPD levels up.
5.Public health
There is an important need for recent, reliable, and
high-quality health information to be made available to the public as
well as in summarized form for public health providers.
ADVANTAGES AND DISADVANTAGES
Advantages
1) Improved open access to education, including access to full
degree programs
2) Better integration for non-full-time students, particularly in
continuing education
3) Improved interaction between students and instructors
4) Acquisition of technological skills through practice with
tools computers
5) No age-based restrictions on difficulty level
Disadvantages
1) Ease of cheating
2) Bias towards tech-savvy students over non-technical
students
3) Teachers’ lack of knowledge and experience to manage
virtual teacher-students interaction
4) Lack of social interaction between teacher and students
5) Lack of direct and immediate feedback from teachers
6) A synchronic communication hinders fast exchange of
question
7) Danger of procrastination
