What is different in elearning?
● Luxury of facetoface communication may not be available.
● Multimedia content has to be meaningful and useful even in standalone mode.

Some questions
● How to get students to use elearning?● They are the final consumers of the content!● Students naturally have a positive attitude towards new
media and technology.● We need to adapt the content to their requirements –
flexibility (anytimeanywhereanydevice), interactivity, modularity, short attention span, ...
● Quality of content is the deciding factor.

When is elearning not meaningful? 1● It consists of text pages with next buttons.
● Might as well print it and read the book.

● Distracts the user.

When is elearning not meaningful? 3
● Interactivity is low.● Difficult to keep reader interest without this.

What usually goes wrong?
Content creators focus on effort minimization.● Teachers convert their classroom teaching into audio
lectures or video lectures.● Add some slides and in some cases animations.
Why?● Overworked, underpaid teachers.● Forget to keep in mind that the learner is remote.

Take Away● Decisions on appropriateness and quality of content are key!
● Otherwise lot of effort can go into creating ineffective content.
● Finegrain modules are likely to be more useful than monolithic.
● Interactivity is essential in most cases.
● Look for Open Source or Creative Commons content repositories before creating your own.
● Release your own work into above repositories.
● Quality contents will require collaboration among experts in:
● Domain (Teachers)
● Technology (Programmers)
● Design (Artists)
