Overview

1. A lesson is made up of a number of pages.
2. A page contains some content and it normally ends with a question.
3. Each page normally has a set of answers.
4. Each answer can have a short piece of text which is displayed if the answer is chosen. This piece of text is called the response.
5. Also associated with each answer is a jump. The jump can be relative - this page, next page - or absolute - specifying any one of the pages in the lesson or the end of the lesson.
6. By default, the first answer jumps to the next page in the lesson. The subsequent answers jump to the same page. That is, the student is shown the same page of the lesson again if they do not chose the first answer.
7. The next page is determined by the lesson's logical order. This is the order of the pages as seen by the teacher. This order can be altered by moving pages within the lesson.
8. The lesson also has a navigation order. This is the order of the pages as seen by the students. This is determined by the jumps specified for individual answers and it can be very different from the logical order. (Although if the jumps are not changed from their default values the two are strongly related.) The teacher has the option to check the navigation order.
9. When displayed to the students, the answers are always shuffled. That is, the first answer from the teacher's point of view will not necessarily be the first answer in the list shown to the students. (Further, each time the same set of answers is displayed they are likely to appear in a different order.)
10. The number of answers can vary from page to page. For example, it is allowed that some pages can end with a true/false question while others have questions with one correct answer and three, say, distractors.
11. It is possible to set up a page without any answers. The students are shown a Continue link instead of the set of shuffled answers.
12. For the purposes of grading the lessons, correct answers are ones which jump to a page which is further down the logical order than the current page. Wrong answers are ones which either jump to the same page or to a page further up the logical order than the current page. Thus, if the jumps are not changed, the first answer is a correct answer and the other answers are wrong answers.
13. Questions can have more than one correct answer. For example, if two of the answers jump to the next page then either answer is taken as a correct answer. (Although the same destination page is shown to the students, the responses shown on the way to that page may well be different for the two answers.)
14. In the teacher's view of the lesson the correct answers have underlined Answer Labels.
15. The end of the lesson is reached by either jumping to that location explicitly or by jumping to the next page from the last (logical) page of the lesson. When the end of the lesson is reached, the student receives a congratulations message and is shown their grade. The grade is (the number of correct answers checked / number of pages seen) * the grade of the lesson.
16. If the end of the lesson is not reached, when the student goes into the lesson they are given the choice of starting at the begining or picking up the lesson where they answered their last correct answer.
17. For a lesson which allow re-takes, students are allowed to re-take the lesson until they have achieved the maximum grade.
