1. Introduction (I)

Standard Education

Webbased Learning Systems

INTERNET

Guide student’s interaction to educational goals

clearly specified.

Learning tasks that can measure those goals success.

Focused in the

learning process NOT

content

Nowadays, every online course:

to the student's learning process

ADAPTATION

1. Introduction (II)

• Objetive

improve

ADAPTABILITY

of

dotLRN

Learning Management System(LMS)

to the student's learning process

¿ How ?

Integrating

grail (IMSLD)

assessment (IMSQTI)

¿ For what ?

Esssential

process in a University with a large number

to afford a personalization

of students such as

UNED

scalable

flexible

Advantages

of development based on IMSLD and IMSQTI:

properties

open/flexible way of representing student's

information

their preferences

their knowledge

their interests

more complicated operations

for groups

collaborative learning activities

synchronization

more adapted context

IMSLD B level

properties update based on

intermediate events

4. Application to ADAPTAPlan &

EU4ALL

• ADAPTAPlan

• EU4ALL

IMSLD Learning Courses that use properties to specify:

a)

student learning style

b)

student knowledge

c)

Felder and Silverman Learning Style Model

d)

Bloom's Taxonomy of Educational Objectives

Adapt a course on Object Oriented Programming –

OOPC

presented in

IJCSA08

, to exploit

IMSQTI adaptive functionality

Scenario 1 –

Student registers in a learning course

Scenario 2 – S

tudent gets familiarized with the virtual learning environment

5. Conclusions

Definitive

integration

between

grail (IMSLD)

and

assessment (IMSQTI)

Application to ADAPTAPlan & EU4ALL projects

dotLRN evolution

Improve

adaptability

to learning processes

thanks to evaluation

(18)

6. Future Work

• Code Publishing (UNED and OpenACS)

• Continue with dotLRN evolution

– Improving its adaptability to the student preferences

– Extend

assessment

package developing

IMSQTI
