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.

● Interactivity plays an important role.● Why is interactivity important?● How to include interactivity in various modes of e­learning?

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.

When is e­learning not meaningful? ­2● It has more frills than substance.

● 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)
