What is Virtual What is Virtual Campus?Campus?
Ideal study environment for the “life-long” learners Providing
up-to-date demanding learning materialsup-to-date demanding learning materials personal study guidepersonal study guide
Students can customize their study in own pace
Delivery the “own-paced” material to the right person in any time.

Why is scheduling worth Why is scheduling worth studying?studying?
Practical Expensive when it is done
manually Not require real-time
response Not need to handle noisy
sensors and effectors
Differences from the used time Differences from the used time tabling problemtabling problem
Less limitations in resources
No more restrictions in lecturers, rooms and the restrictions of their use
Time restrictions still exist but in a relax manner
Differences from the used time Differences from the used time tabling problemtabling problem
Different purposesUsed Time Table: Arranging periods, modules, rooms and lecturers to all courses in an academic year
Scheduling in Virtual Campus: Producing a customized study guide for each students
Personal Scheduler - Smart Scheduler Personal Scheduler - Smart Scheduler (S-Scheduler)(S-Scheduler)
1. Student’s- personal preference- academic record
2. Instructor’s recommendation
3. Available resources4. Other relevant
factors

Update the student database(says, course pointers for particular student)
Future WorkFuture Work
Continue to Implement the mentioned functionality
Make use of JCE to build the communication channels between people in Virtual Campus
Study and implement the S-scheduler
ConclusionConclusion
State out the importance of customization Describe the basic logical and technical flow Describe the basic interface of Virtual
Campus Introduce the S-scheduler
Q&AQ&AThank Thank

What’s in Virtual Campus?
Students fully engage in the learning process
through an interactive, dynamic environment
study personal scheduled on-line materials accomplish group project and discussion seek help/advice from instructors
What’s in Virtual Campus?
Instructors Delivery the lectures as usual, BUT through
the WWW (Internet) to access students Answer the questions from students in real-
time mode (just like in traditional classroom) OR non-real mode (by email or notice broad)
provide a channel for personal communication with students (collaboration - just like tutorial)
What’s in Virtual Campus?
Learning material provider shorten the distance with students gather the demanding materials
Personal scheduler consultant/counseller for each student re-arrange the order of the course
material according to each student’s pace
Changing Trend of Learning Style
Student-centeredteacher-centered
Students’ monotonously
Lecturing monotonously

New Learning Process
Customized learning strategyComponents of learning strategy Expected achievement
Choice of individual/group learning Depend on personal style(selection of synchronized/asynchronized mode lecture)
+ Collaboration Learn to solve problem together(social interaction)
+ Customized learning progression Instructor/scheduler advisedpace (personal pace control)
+ Efficient personal support Establish closer relationshipbetween instructor and students
Delivery the right knowledge to right people in right time
New Learning Process (cont’) Changed behavior of roles
Role Changes Expected behaviorStudent From
passive toactive
state out what they need and want decide which learning mode fit themselves encourage participation
Instructor
Instructor present the material answer the question from the students
about the material relatively less leader character from “chalk-and-talk” role to “guide-on-
the-side” rolePersonalScheduler
analyze the learning pattern of each student give study advice to the student listen to the student personal consultant
New Learning Process (cont’)
Relationship between demand and supply
Consequence StatusDemand >Supply Not fulfill the
enthusiasms of learningPresent
Demand =Supply Just in time deliverywhen knowing the
demand
Hard to seek andprepare the
material in time
Demand <Supply Customize switchingresource
