ONLINE LEARNING
e-Learning is the use
of technology to enable people to learn anytime and anywhere. e-Learning can
include training, the delivery of just-in-time information and guidance from
experts. E-learning (or eLearning) is the use of electronic media, educational
technology and information and communication technologies (ICT) in education.
E-learning includes numerous types of media that deliver text, audio, images,
animation, and streaming video, and includes technology applications and processes
such as audio or video tape, satellite TV, CD-ROM, and computer-based learning,
as well as local intranet/extranet and web-based learning. Information and
communication systems, whether free-standing or based on either local networks
or the Internet in networked learning, underly many e-learning processes.
TYPES OF ONLINE LEARNING
Synchronous and
asynchronous
E-learning may either
be synchronous or asynchronous. Synchronous learning occurs in real-time, with
all participants interacting at the same time, while asynchronous learning is
self-paced and allows participants to engage in the exchange of ideas or
information without the dependency of other participants′ involvement at the
same time.
Synchronous learning
refers to the exchange of ideas and information with one or more participants
during the same period of time. Examples are face-to-face discussion, online
real-time live teacher instruction and feedback, Skype conversations, and chat
rooms or virtual classrooms where everyone is online and working
collaboratively at the same time.
Asynchronous learning
may use technologies such as email, blogs, wikis, and discussion boards, as
well as web-supported textbooks, hypertext documents, audio video courses, and
social networking using web 2.0. At the professional educational level,
training may include virtual operating rooms. Asynchronous learning is
particularly beneficial for students who have health problems or have child
care responsibilities and regularly leaving the home to attend lectures is
difficult.
PURPOSES OF ONLINE LEARNING
A Flexi-Time Approach
An e-Learning offers a flexible time and location approach
by changing the learning environment. It enables learning to take place in a
variety of different places, both physical and virtual. Learners now have a
choice and as a result increasingly wish to combine the options, choosing when
and where they study and learn.
A Mixed-Mode, Blended
Approach
E-Learning was misinterpreted after it
was first introduced. It was oversimplified and wildly optimistic. Some
described e-Learning as putting all learning on computers. They felt that
e-Learning could result in savings in instructor salaries, and could keep
students out of the classroom. They felt students could learn anywhere,
whenever they wanted, and could save time by studying only what they needed,
and could learn at an optimal pace, neither to be held back nor bypassed by the
rest of the class. But they forgot that learning is a social experience. Even
in the classroom much learning takes place informally in exchanges between
students. Most people learn better when computer-mediated lessons are combined
with virtual classes, study groups, team exercises, mentors and help desks,
off-line events, and online coaches. The act of learning itself has not
changed. Computers can make aspects of learning more convenient, but they do
not eliminate the need for human intervention.
A Student-Centred
Approach
An e-Learning package not only
provides a marriage of Internet, digital technology, and learning, it also
facilitates student/ learner centred learning. In recent years, there has been
a shift from the teacher/ instructor-centred approach to a student-centred
approach.
In this
approach, students gain expertise not only in the content area being studied,
but also in learning process itself – i.e., how to learn through discovery,
inquiry, and problem solving. Thus it was felt that a student-centred
e-Learning package would be appropriate for the new generation.

BLOG
A blog
(a truncation of the expression weblog) is a discussion or informational site
published on the World Wide Web and consisting of discrete entries
("posts") typically displayed in reverse chronological order (the
most recent post appears first). Until 2009 blogs were usually the work of a
single individual, occasionally of a small group, and often covered a single
subject. More recently "multi-author blogs" (MABs) have developed,
with posts written by large numbers of authors and professionally edited.
Variations of the
term blog :
·
Blogging: The act of writing a post for a
blog
·
Blogger: A person who writes content for a
blog
·
Blogosphere:
The online community of blogs and
bloggers
There are many different types of blogs, differing not only
in the type of content, but also in the way that content is delivered or
written.
Personal
blogs
The personal blog is an ongoing diary or commentary written
by an individual.
Microblogging is the practice of posting small pieces of
digital content—which could be text, pictures, links, short videos, or other
media—on the Internet. Microblogging offers a portable communication mode that
feels organic and spontaneous to many and has captured the public imagination.
Friends use it to keep in touch, business associates use it to coordinate
meetings or share useful resources, and celebrities and politicians (or their
publicists) microblog about concert dates, lectures, book releases, or tour
schedules. A wide and growing range of add-on tools enables sophisticated
updates and interaction with other applications, and the resulting profusion of
functionality is helping to define new possibilities for this type of
communication. Examples of these include Twitter, Facebook, Tumblr, and by far the largest WeiBo.
Corporate and organizational blogs
A blog can be private, as in most cases, or it can be
for business purposes. Blogs used internally to enhance the
communication and culture in a corporation or externally formarketing, branding or public relations purposes are called corporate blogs. Similar blogs for clubs and societies are called club
blogs, group blogs, or by similar names; typical use is to inform members and
other interested parties of club and member activities.
Some blogs focus on a particular subject, such as political blogs, health blogs, travel blogs (also known as travelogs), gardening
blogs, house blogs, fashion blogs, project blogs, education blogs, niche blogs, classical music
blogs, quizzing
blogs and legal blogs (often referred to as a
blawgs) or dreamlogs. How To/Tutorial blogs are becoming increasing popular. Two common
types of genre blogs are art blogs and music blogs. A blog featuring discussions especially about home and family is not uncommonly called
a mom
blog and one made popular is
by Erica Diamond who created
Womenonthefence.com which is syndicated to over two million readers monthly.
While not a legitimate type of blog, one used for the sole purpose of spamming
is known as a Splog.
By media type
A blog comprising videos is called a vlog, one comprising links is called
a linklog, a site containing a portfolio of sketches is called
a sketchblog or one comprising photos is
called a photoblog. Blogs with shorter posts and mixed
media types are called tumblelogs. Blogs that are written on typewriters and then scanned are
called typecast or typecast blogs; see typecasting
(blogging).
By device
Blogs can also be defined by which type of device is used to
compose it. A blog written by a mobile device like a mobile phone or PDA could be called a moblog. One early blog was Wearable
Wireless Webcam, an online shared diary of a person's personal life combining
text, video, and pictures transmitted live from a wearable computer andEyeTap device to a web site. This
practice of semi-automated blogging with live video together with text was
referred to as sousveillance. Such journals have been used as
evidence in legal matters
A Reverse Blog is composed by its users rather than a single
blogger. This system has the characteristics of a blog, and the writing of
several authors. These can be written by several contributing authors on a
topic, or opened up for anyone to write. There is typically some limit to the
number of entries to keep it from operating like a Web Forum.
Edublog
An edublog is a blog created for educational purposes.
Edublogs archive and support student and teacher learning by facilitating
reflection, questioning by self and others,collaboration and by providing contexts for engaging
in higher-order thinking. Edublogs proliferated when blogging
architecture became more simplified and teachers perceived the instructional
potential of blogs as an online resource. The
use of blogs has become popular in education institutions including public
schools and colleges. Blogs can
be useful tools for sharing information and tips among co-workers, providing
information for students, or keeping in contact with parents. Common examples
include blogs written by or for teachers, blogs maintained for the purpose of
classroom instruction, or blogs written about educational policy.
Importance of Teacher
Blogging
It is necessary
for teachers to be writers and to share their strategies, lessons, and
resources with one another, as they are able to provide glimpses into our daily
lives, while sharing effective ideas that are realistic and
classroom-tested. In the past, teachers would submit articles to various
teaching journals, wait several months for approval, then finally see their
work published. Now, blogging has become a fast, effective, and easy way
for teachers to become writers and publish content.
When blogs
first began in the 1990s, they were mainly used to share interests and hobbies
or to become an online journal. But times have changed, and you can now
find a blog on practically any topic. According to NM Incite, by
the end of 2011, there were “over 181 million blogs around the world, up from
36 million only five years earlier in 2006.” This dramatic increase in
the number of blogs and blog readers shows how significant blogging has become
for people to learn new things, share ideas, and express their thoughts.
Top Science Teacher Blogs
Bringing the subject
of science to life for students is the challenge shared by the teachers who
author amazing and insightful science education blogs. Sharing narratives set
within and beyond the classroom walls, these next generation educators embrace
technology but are never so dazzled by it that they lose sight of their common
goal.
