I have gone through the "How to use Lesson Module" three times. Apparently, what the lesson says is not what is computed. The Lesson Module actually averages all the grades and displays the average not the highest grade as indicated in the "lesson". Since these lessons as meant to be for purposes of learning (summative) and not for testing, wouldn't it better to display all the grades.
It might be helpful to the student and the teacher.
Is the teacher about to see in detail each of the "answers" for a better understanding of where students are having difficulty with certain concepts, ideas or knowledge? I haven't not been able to see this on this site. Not been able to explore my own site yet (some probably with the server behind the firewall).
I seems to have read somewhere in the lesson that a students should be able to see his detailed grades in the activity reports but I have not been able to see this on this site. I only got to see page once in my three attempts (graded 5, 10 and 5, average 6.7).
