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

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

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

Active and collaborative learningPassive learning

Educational Focus

Learning Style

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
