Dear Tasrun,
A lesson is a chapter as mentioned by us. At IGNOU we use the term
Unit for a Lesson/ Chapter. For you a Lesson is a Chapter. As you know
each chapter/lesson can have some sections and sub-sections. For the
questions at the end we recommend different types. All these will be
discussed in the F2F workshop. For example, Self-Assessment Questions
can be spread over the chapter within the sections and sub-sections.
We have recommended practice Test at the end in our template. I will
show the use of activity template in your talk page.
with best regards, Sanjaya
