Introduction
Advancements in Information and CommunicationTechnologies have opened up new challenges andopportunities in higher Educational Institutions.
There is steep rise in internet usage around the world duringthe last decade.
Connectivity and instant access have opened up new vistas
in many spheres of lives of people. The traditional class room based educational system needs
transformation to catch up with technology.
The learners today have opportunities and flexibility of
learning at any time, any where , and at any pace.

Changing Paradigms
Now the responsibility of Learning has been shifted from teacher
to the learner.
The role of teacher has been changed from instructor to facilitatoror mentor of Learning.
The faculties need empowerment to acquire new skills to facilitate
this transformation.

Virtual Learning EnvironemntProblems & Issues
VLE is a learning Platform which provides web basedaccess to content ,grades, assessments, and other online
learning facilities.
VLE faces problems like Information overload, poorusability , Lost in Hyperspace syndrome.
Majority of professors primarily use Blackboard a) To post
course content , b) to calculate grades , and c) tocommunicate with students via the Announcements tool.
Advanced features like Rubric, Wikis, and blogs are not
widely used. (Janiess Sallee et al.,2012)

Research Gap in E-Learning
SWEEPING EXPECTATIONS ON E-LEARNING
Putting the learners in the center of study process andexaggerating their self-directed abilities.
The new technologies would transform teaching and learning
process from being highly teacher dominated to student
centered and the students would develop problem-solving
abilities, creativity and higher order thinking skills.
However study by Guri-Rosenblit (2009,2011) ,there exists
noticeable gap in e-Learning research.
There is limited research to support these claims.

Self Regulation
Self Regulation Key Indicator
Since E-Learning heavily depend on shifting the responsibility fromthe Instructor to Learner, Self regulated learning is a key-indicator for
enhancing the learning outcome of the learners.
Zimmerman(1990) , David J. Nicol (2006) emphasize learners to
assume responsibility and control for their own acquisition of
knowledge and skill.
Some self Regulated Learning Strategies are a) Self-evaluation b)
Goal setting and Planning, c) Self-monitoring etc.
All researchers agree Self Regulation depends on continuous feed back
of learning effectiveness.

Why UML
Modeling ?
The Three
Amigos
The Unified Modeling Language
(UML) was developed by
Grady Booch,
Jim Rumbaugh and
Ivar Jacobson
(the Three Amigos)
as a way to define large
complicated systems.

Why UML Modeling ?
In a Software Production Process, the Conceptual Modelsare Key Inputs in the process of Code Generation.
The Conceptul Models must provide a holistic view of all
components of the final application and the interactionamong components of the systems.
The Model should support the structure , behavior and the
interaction between the users and the system. UML is a defacto standard for modeling Software Intensive
systems.

Why UML Modeling ?
Modelingcreating simplified representations of various aspects of asoftware system (prior to building it) that convey information about the
system from a variety of perspectives.
UML serves as a blueprint that bridges the gap between the world that
customers, users, and analysts understand and that of the developers,
engineers, and architects implementing the system.
UML provides an industry-standard way to model systems before
building them and to talk about system features and capabilities by
using an easy-to-understand, ageless graphical paradigm to effectively
capture requirements and document system design.

Why UML Modeling ?
software development is fundamentally hard, and theway we counter that complexity is by abstraction.
The UML permits a team to visualize and construct
abstractions that transcend the underlyingimplementation language.
smooth mapping from the highest level enterprise
architecture abstraction to the software systemabstraction to the implementation in code.
UML is a single communication tool from inception to
implementation.

Grady Booch about future of UML
One other thingin terms of where the UML is headedisthat I was blown away recently when I discovered an article
called The Systems Biology Graphical Notation.
Apparently it was inspired by the UML as an attempt to build
a standard for biologists for modeling things within their
worldthings like mechanisms within cells and the like. So
thats an example of where the UML has extended its reach
far beyond whatever I imagined. Thats pretty cool, and italso tells me that the language does have staying power; its
going to be around here for a long, long time. We do need to
simplify and refactor it

Exerpts from Ivar Jacobsons
Blog- UML is Evolving Distinctive features of the new use cases are:
As agile and light as you want it to be
Scaling up, scaling out and scaling in - to meet your
needs
Its not just about requirements - it's for the whole
lifecycle
It's also for non-functional requirements
Its not just for software development - it's for business
as well

UML Modeling and Self
Regulation
Self Regulation can be easily accommodated in UML.
An e-learner could be in different states in a course life cycle like
enrolled, certified , accessing content, taking test, and received score
card etc.
The student can be notified at appropriate time his progress in learning
so that he can adopt different learning strategies which helps towards
enhancements in his learning outcome.
UML Design Patterns are helpful in conceptualizing various Self
Regulated Learning Strategies like goal-setting, Self-evaluation, self-
monitoring and help-seeking etc.

UML State Machine
Diagram
Students Role in E-
Learning
The diagram shows a
UML state machine
diagram representing
students role in E-
Learning.
In the course life cycle, a
student can be in any one
of different possible
states.
For example, when a
student browses through
the E-Learning content, he
moves to the self-learning
state.

Pilot Study and Experimental
Findings
Experimental Set-up
An experimental setup was made which illustrates a typical e-
learning system.
A pilot study was done to understand the self regulatory
behavior of under graduate students of Information Technology
course.
A departmental web site is hosted and the faculties uploadcontents on many subjects and topics.
The tools used are Google Sites, Google Docs etc. Google Sites
is an easy way to create and share web pages.

Questionnaire on Learner PreferencesWeb Refer I refer to web material as additional resource in learningDownload notes I have referred to educational web sites like edunotes.in to download
subject notesGet Overview I strongly prefer to get an overview of the subject before start learningComfortable in Text I like to read the subject in text form and comfortable in understandingHearing Lectures I would like to understand the subject by hearing what the lecturer
teachesVisual I understand the subject better with diagrams, graphs, charts etc than text
matter and I like maps to know directionsMultimedia I like to refer to multimedia content like to video to understand the
subject.
Text Important I consider textual content is important like use cases are text storiesin UML notation
Down loadimportant I prefer downloaded notes of all topics are very important inunderstanding the subject, exam point of view.All media important
I consider audio, visual, text, video content and lab exercises areequally important for gaining knowledge

Learning Preferences Survey
The main idea of Survey was to
collect the voice of the students based
on 10 criteria on learning preferences.
It can be seen from the chart that
majority of students belonging to two
groups have responded positively for
the criteria on learning preferences.
It can be inferred that E-learning
framework has a positive impact on the
focused group and it helps the students
to enhance their learning outcome better
than class room lectures.

ConclusionThis research work highlighted faculty empowerment as the key
indicator in fostering self regulated learning.
A UML based e-learning model was suggested in this work which
provides a controlled environment in which self director learners can
become autonomous.
This study hypothesizes that an UML based model helps inconceptualizing an e-Learning framework with holistic and serial-
based view and also Self Regulation can be implemented with UML
Design Patterns.
A pilot study was done using a web based experimental set up wherea faculty was empowered for creating content, provided with tools for
monitoring states of student learning processes.
The student feedback and reports on web analytics confirm that
there are interesting pattern exists in student learning behavior.

Future Directions The present workis preliminary.
Concrete experimentation needed to support the proposed UML
Model.
UML Modeling, Self-Regulated Learning, and Faculty Empowerment
are separate concepts.
More experiments and evidence needed to prove that the suggestedmodel helps to improve student learning outcome.
The pilot study has to be scaled up covering a larger audience.
More studies
o
to establish correlation between site visits, page views andLearning outcomes.
Educational Data Mining Techniques can be adopted .
o Automatic analysis of web log data.
o Generation of visual reports
o Pattern analysis and knowledge discovery
