Structure online course packages in courses, chapters

Hi all,

we are currently setting up online learning courses for our software products and have a discussion about structuring the courses, respectively how to name the structure units.

For our classic instructure-led classroom trainings we have the following:

Course:

          Lesson 1:

                Chapter 1.1

                 Chapter 1.2

          Lesson 2:

                 Chapter 2.1

                 Chapter 2.2

For our online learning courses it makes sense to have every lesson (1-max.2 hrs duration) converted in an online learning course

So the structure would be:

Course 1:

     Chapter 1.1

     Chapter 1.2

and so on.

I am fine with this structure, but some of my colleagues do not feel comfortable with the term "Chapter". What do you think?Is chapter an appropriate term for structuring an online course or is this more related to books like novels.

Thanks a lot for your feedback.

Caroline
