Online Staff and Student
Interaction
ABSTRACT
Grid
computing promises a standard, ‘complete’ set of distributed computing
capabilities. In “Online Staff Student Interaction Project”
we must provide basic functions such as resource discovery and information
collection & publishing, data management on and between resources, process
management on and between resources, common security mechanism underlying the
above, process and session recording/accounting.
Main
advantage of this project is, a network of distributed resources including
computers, peripherals, switches, instruments, and data. Each user should have
a single login account to access all resources.
We
start by analyzing the nature of Grid computing and its requirements for
knowledge support; then, we discuss knowledge characteristics and the
challenges for knowledge management on the Grid.
INTRODUCTION
In
this project, we examine the semantic aspects of e-learning from both
pedagogical and technological points of view. We suggest that if semantics are
to fulfill their potential in the learning domain then a paradigm shift in
perspective is necessary, from information-based content delivery to
knowledge-based collaborative learning services.
We
propose a semantics driven Knowledge Life Cycle that characterizes the key
phases in managing semantics and knowledge, show how this can be applied to the
learning domain and demonstrate the value of semantics via an example of
knowledge reuse in learning assessment management.
As
e-learning applications become more integrated and e-learning systems more
distributed, there is an increased need to manage their software and data components.
There
is a trend in the distributed systems and middleware areas of computing towards
Service-Oriented Architectures (SOA), these emphasize loosely coupled
components that interoperate by providing distinct services through
standardized interfaces.
In particular the grid is evolving as an SOA
for securely orchestrating and sharing crateful services and resources across
distributed or virtual organizations.
Both
web and grid service architectures have been applied to the e-learning domain,
the argument is that they are advantageous as they are modular and extensible
and offer increased interoperability to software producers.
While
grid services were originally conceived as a method of distributing high
performance computation, they also offer benefits in distributed knowledge and
information management, offering a guaranteed level of security that is
essential for serious e-learning applications.
We
believe that the semantic aspects of learning content are the key to
facilitating large-scale collaboration of e-learning activities over
service-oriented infrastructures. To use explicit and accurate semantics, a
consensus in the domain at the conceptual level is necessary, so that computer
and human participants can understand and communicate.
Ontology
is the best vehicle in this context to formally hold a pacification (of the
conceptualization) that can be shared within the community to describe
semantics accurately and consistently. An ontology explicitly defines the
domain concepts and their relationships and is similar to a dictionary or
glossary, but with richer structure, relationship and axioms that describe a
domain of interest more precisely.
These
rich semantics offer both teachers and learners new opportunities for locating
and reusing resources. But defining the correct semantics for a learning
application is difficult and maintaining ontologies can be problematic (akin to
managing the evolution of a complex graph).
We
propose a Knowledge Life Cycle for learning, to help define and maintain
evolving semantics. Our intention is not to develop a definitive ontology or to
promote a particular architecture, but to demonstrate how a semantic-driven
Knowledge Life Cycle model can be applied to the learning domain.
In
this paper, we present an overview of the semantics involved in learning,
present the Knowledge Life Cycle and show the advantages of rich semantics via
a demonstration of knowledge reuse.
Connecting
communities:
Services
can put people in contact with other people who are experts or learners with
similar interests
Personalized content:
Intelligent tutoring systems have for some time being
delivering content that was personalized for the user, based on an
understanding of their goals and previous knowledge
Personalized
sequencing:
Adaptive
Hypertext Systems attempt to provide pathways through materials by matching
domain ontologies with dynamically evolving user models
Adaptive
assessment:
Systems
may choose questions for the learner at the boundary of their understanding;
thus, improving the efficiency of assessment and providing feedback that
provides detail in critical areas
Feedback
agents:
Intelligent
agents that observe student behavior (e.g. assessment results, interactions
with a virtual experiment, etc.) can attempt to provide feedback and links to
suitable material to assist the learner
Recommender
agents:
The
system could recommend alternative resources based on user searching and
studying patterns. In a formal setting, it could query the syllabus and
timetable to recommend a plan of study
Annotation
tools:
Users
could annotate information themselves, providing useful information for others
and allowing both readers and other services the opportunity to process the
information in alternative ways
Search
engines:
When
resources have been semantically enriched, then search engines can be much more
powerful. Where services are semantically enriched, search engines can choose
suitable services to manage the query
Analytic
tools:
The
e-science community is leading the way in the production of tools that harvest,
store and analyze data from a range of sources.
How
semantic enrichment can improve the management of learning
E-learning practitioners
often comment that they believe they spend as much time organizing materials as
they spend on teaching and the production of materials. We believe that
semantics may ease this problem in a number of ways:
Production
of materials:
Production
of teaching materials is a notoriously time-consuming task and the ability to
locate and to reuse existing materials is a primary motivation for providing
metadata for learning resources. The next stage is to provide services to
assist in the location of suitable materials from heterogeneous sources.
Student
management:
An
understanding of the roles of the actors (teachers, students, experts,
assessors, etc.) makes the production of services for assigning students to the
correct classes, discussion groups, experimental teams, etc., possible.
Timetable
management:
An
important task for teachers of online tasks is the timing of events, such as
the release of some new materials, the closing date of some assessment, the
exact time of a synchronous group chat session, etc. These events can be made
to happen automatically when a course is described in some language such as IMS
Learning Design
Record
keeping:
Record
keeping and quality assurance can be the bane of a teacher’s life, requiring
them to spend much time ensuring that all the results are kept in the correct
places such as institutional enterprise systems, student portfolios as well as
made available for QA purposes by whatever external authorities might be
involved. All of this work is an obvious target for automation by services that
understand the goals.
Quality
assurance:
Quality
assurance often involves the maintenance of sample work and
feedback/reflections, as well as ensuring that new programmers, courses and
assessments have been through appropriate validation. Again, this is a task
that could be assisted by intelligent services, which could guide such tasks
through the set of other services involved.
EXISTING SYSTEM
Knowledge
management has six problems in knowledge life cycle. That is acquiring,
modeling, retrieving, reusing, publishing, and maintaining knowledge. Grid are
how to acquire, formally model, explicitly represent, store, maintain,
and update them, and to use them to support seamless resource sharing and
interoperability, so as to achieve a high degree of automation.
PROPOSED SYSTEM
We
analyze the nature of Grid computing and identify its requirements for
knowledge management. We further argue that an innovative and systematic
approach to knowledge management on the Grid is required in order to help
achieve the goal of the Grid.
Our
contributions are three folds: First, we propose the Semantic Web-based
approach to managing heterogeneous, distributed Grid resources for Grid
applications. Second, we design architecture to realize the proposed approach
and conceive a methodology which addresses the complete life cycle of knowledge
management. Third, we apply the approach, concepts, and methodology to a
real-world Grid application.
