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.


5/29

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)


7/29

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.


8/29

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.


10/29

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.


11/29

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.

Guus Ramackers

Oracle principal product manager for UML and cochair of the OMG's


12/29

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.


13/29

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

14/29

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

Ivar Jacobson October-2011


15/29

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.


19/29

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.

Web Site Usage for Three

Years

The chart shows a plot

of the web usage statistics

for the month of April for

the years, 2010, 2011,

and 2012.

It can be seen from the

graph that there is a

steady increase in visitors

and pages referred for thelast three years.

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.


27/29

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.


28/29

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
