E-learning by Design...

I have a question? when you deisn E-learning course, how do you introduce the topic?

do we need an introduction? a well done introducion will help learner see how th topic relates to other topics and it will see all courses information. In my experiences, a good introduction can be

(1)we may need more motivation for our students

(2)to tell our learners who you are in the right places. learners need to go to right topic. it gives them enough information to inform them whether to continue with the topic
(3) teachers set the context for the rest of the content of the topic.
(4)learners can preview context

is there anything left?
