application transformation towards mobile
social learning
Evolution of
Smartphone
Mobile technology user has increased three
times in 2008 and it is projected to reach 89

the most mobile learning user after USA.
Today, smartphone has various platforms,
such as Java Android, Symbian, Bada, iOS,
and Windows Phone.
Evolution of
Smartphone
Android becomes the leader of smartphone
in the world today. In Indonesia Android has
52% market share in second quarter.
Learning
Paradigm
Learning concept which is currently teacher
centric has been shifted to the new
paradigm in which learners can participate
in developing learning process and content.

Social Mobile
Learning
• In many years, learning model which is
used is face to face in class, with one way
conversation from the teacher to
student.
• Most e-Learning today just automates
that process.
• The difference is only that in e-Learning,
the teacher and student do not need to
stay in the same place at the same time.Social Mobile
Learning
Cross (2003) stated that learning process
often happen in informal situation, such as
observation on someone else, asking to
peer, calling help desk, trial and error, or
cooperate with someone else in
understanding the material.Social Software
Approach
Social software approach gives several
advantages for online learning in compared
with traditional approach.
Besides, this approach represents the shift
Natural Characteristic of Learning
of learning management system model to be
more social, personal, open, and dynamic.

Collaboration
Social network collaboration creates online
communities and mobility to be favorable
delivery channel, not only to improve return
on investment, but also to expand the global
coverage and improve operational efficiency
of workers in company or institutionE-Learning 2.0
Social software implementation inspires
development of new e-Learning generation,
called e-Learning 2.0, featuring:
Learning is about
generating course
Social or collaborative Aggregating (RSS) and
contents and Knowledge sharing
learning Environment tagging
communicating with
people.
Collective intelligence Network usage with
Personalization
(wisdom of the crowd) various technology.Research
Objective
The research objective is defined as learning
management system enhancement
featuring mobile social learning based on
Android technology and Java Technology.Research
Methodology
This research uses ADDIE instructional
design model. As mentioned from its name,
ADDIE defines five steps, those are analysis,
design, development, implementation, and
evaluation.Research Methodology
M-Learning 2.0 • Mobile learning design refers to National E-Learning eXchange Technology (NEXT) • The concept is about a mechanism to learn from various sources, not just focused on reference given by teachers. This mechanism is called multisourcing concept. • The NEXT is in line with e-University concept
