Background info: About me

• Darko Grabar Working at University of Zagreb, Faculty of

Organization and Informatics

Head of Software Development Center and E-learning Support Center

Softer developer with strong relation to Open source and e-learning

Involved in e-learning projects since 2005

Participated in development of several e-learning strategies at institutional and country wide level

Background info: Why this topic

• This is what I do Trying to be one step ahead of teachers by predicting

future usage of ICT in learning

• E-learning is at its turn point New Web 2.0 technologies LMS crisis Bigger gap between rich and poor

• Cloud technologies are ready To be used by masses To provide cheep, reliable and powerful services

E-learning today

E-learning is a process of education (learning and teaching process)

conducted using the Information and Communication Technology which

improves the quality of the process itself and the quality of its result

E-learning today

Why the future is not here?

What are the problems?

Software is available

Hardware can support it

Network is ready

There are people that know how to use new technologies

Students/children are demanding it

Page 10: Darko Grabar Accessible e-learning in the cloud

E-learning today

Resources!

If there would be enough resources:• Schools would hire more teachers• They would have experts in ICT and e-learning• They would have appropriate ICT equipment• Teachers would have time to produce

quality e-learning materials• ICT staff would have time to provide top-of

the line environment for e-learning• Students/pupils would be able to use it • And the list goes on…

E-learning today

• So what’s wrong with e-learning today?

Outdated technology Closed systems Slow innovation Lack of resources

Money ICT resources People

Available only to “privileged”

What is “The Cloud?”

Page 14: Darko Grabar Accessible e-learning in the cloud

What is “The Cloud?”

End user

E-learning professional

ICT support

Page 15: Darko Grabar Accessible e-learning in the cloud

What is “The Cloud?”

Cloud computing is the use of computing resources (hardware and software) that

are delivered as a service over a network (typically the Internet)

Cloud computing entrusts remote services with a user's data, software

and computation

Wikipedia

Page 16: Darko Grabar Accessible e-learning in the cloud

What is “The Cloud?”

It is “a mechanism for delivering scalable business services that

execute on a decentralized computing fabric composed of

commodity software and hardware”

Page 17: Darko Grabar Accessible e-learning in the cloud

What is “The Cloud?”

It is a “pay-per-use model for enabling available, convenient, on-demand

network access to a shared pool of configurable computing resources”

Page 18: Darko Grabar Accessible e-learning in the cloud

What is “The Cloud?”

Not a new idea

Page 19: Darko Grabar Accessible e-learning in the cloud

What is “The Cloud?”

Relies on Virtualization

Page 20: Darko Grabar Accessible e-learning in the cloud

What is “The Cloud?”

Page 21: Darko Grabar Accessible e-learning in the cloud

What is “The Cloud?”

• Infrastructure as a service (IaaS)• Software as a service (SaaS)• Platform as a service (PaaS)• Storage as a service (STaaS)• Desktop virtualization• Data as a service (DaaS)• Database as a service (DBaaS)• Test environment as a service (TEaaS)• API as a service (APIaaS)• Security as a service (SECaaS)• Backend as a service (BaaS)

E-learning and the cloud

Case: teaching ICTGoal:

To provide advanced education in the field of ICT (programming and multimedia) to students in schools in the form of blended e-learning course.

We want to teach two courses Big Data Processing 3D Modeling

Requirements:• Learning Management System for delivering courses• E-Portofilo system for student collaboration • High computing power needed for large files

manipulation and 3D modeling• Large data storage• High speed network

Page 29: Darko Grabar Accessible e-learning in the cloud

E-learning and the cloud

Case: teaching ICT

Let’s do it “traditional way”

We will need:• Server• Install LMS, e-portfolio, databases, ...• High speed network connection• Computer classroom

Screen projector 20 computers (workstation class): fast processor, 8GB of RAM (min),

500GB disk, fast graphic card Windows and Linux OS Install all required software on each computer Fast local LAN connected to high speed broadband connection

• What about when working from home?

Discussion

• Are you using e-learning technologies? What technologies (LMS, e-Portfolio, other?...) Typical examples

• Would you use cloud services if available? In what context If no, why not?

• What functionality would you like to see in the “E-learning in the cloud environment”?
