Moodle 2.2.3 (upgrading to 2.3 on Dec 28, 2012)
I support a Community College and the most challenging part of our Moodle system is the gradebook. My instructors, on the whole, want a fairly simple gradebook. They only want the gradebook to tally points and display some sort of "Running Total to Date" to students. That way, about halfway through the term a student can see that he's earned, for example, 200/250 possible points to date, so his grade at this point is 80%, or "B." I'm having a really hard time setting up a simple gradebook like that. I've read dozens of pages in various Moodle docs (on this site and elsewhere); but those often get bogged down in mathematical formulas and esoteric explanations. Can't Moodle simply add points and divide by the number of points possible at any given place in the term? It would seem not.
The "Sum of Grades" aggregation method doesn't seem to like missing grades and won't total properly if a grade or two is missing. The "Simple Weighted Mean of Grades" may be a winner (at least it handles missing grades), but it uses a percentage as its foundation, and then calculates the category total number of points from the mean of the percentages in that category, which is very confusing. For example, in one class I have a category called Quizzes. I have 6 quizzes, worth 10 points each. One student completed three quizzes for 5, 8, and 10 points, or 23 points total. However, Moodle calculated his score as 5/10 + 8/10 + 10/10 = 23/30 = 76.67%. Then, Moodle multiplied the total points possible for the category (60) times the percentage the student has earned (.7667) and shows that the student earned 46 points. This is, to say the least, confusing to the student.
Can someone recommend a very simple gradebook setup that will let students see their "at this time" score during the term of instruction? This would meet the needs of about 80% of my instructors (I'm guessing at that number, but believe it's reasonable) and help me stop answering an endless stream of gradebook questions at the end of every term.
Thanks for any help you can offer.
