Introduction
WWW RS CF AHS
World Wide Web (www) search anything, anytime and anywhere without boundaries.
Recommender systems (RS) commonly used to help search the desired items,depending on the objects to be recommended; e.g. course to enrol, learning materials etc.
Collaborative Filtering (CF), a system that can find users with similar interests and preferences.
Adaptive Hypermedia System (AHS) share the same goal; personalize the materials to learners’ needs.

RS
Factor of limited time hinders learners from locating suitable learning information, they may end up with unsuitable material.
Nachmais(2003):
Some researchers identified these in RS & AHS, proposed some solutions to overcome the problems.
Though the technologies are personalized , improvement is necessary to suit the learners’ quality preferences and expectations.

Collaborative Filtering (CF)
• I have watched so many good & bad movies.
• Would you recommend me watching “Fast and Furious 5”?
Content-based method (2001),
deployed at Amazon; Eg:
• to pick from my previous list 20-40 movies that share similar audience with “Fast and Furious 5”, then how much I will like depend on how much I liked those early movies.
The idea is

In short:
• People who have watched those movies also liked this movie.

Kangas (2002)
• has the control to filter out whatever unwanted and allow what the users want.

But, what do RS do, exactly? 1. Predict how much you may like a certain product/service.2. Compose a list of N best items for you.3. Compose a list of N best users for a certain product/service.4. Explain to you why these items are recommended to you.5. Adjust the prediction and recommendation based on your feedback and other people.

Ever heard of Adaptive Hypermedia System?
Using a set of algorithms while interacting to the Adaptive Hypermedia system, (AHS) user can select the most appropriate content to be presented (Bhosale 2006).
Adaptive educational hypermedia tailors what the learner sees to the learner's goals, abilities, needs, interests, and knowledge of the subject, i.e.by providing hyperlinks that are most relevant to the user (Wikipedia).

As a Matter of Fact,
Malaysian educational system is exam-oriented (The Star Online 2006 &
Tun Hussin 2006).
Malaysians need a fresh and new philosophy in their
approach to exams (Ahmad 2003).

Conclusion
Future Study
The users need to be involved in a lot of
speculation in the buzz of digital and
education.
Lots of efforts into materialising the
changing for T and L to take place around the
technology.
Ensure technology 3.0 won’t do any harm to
the users.
Teachers/ educators need to discuss and
scrutinise their practice and make explicit pedagogies underpin to meet the
current demands.
