I’m hoping I’ll be able to publicize our proposed gradebook improvements in Moodle 1.9.5 very soon now, perhaps tomorrow!
(To be added to Moodle Docs: Weight is only available for grade items within a category with weighted mean of grades aggregation type. Extra credit is only available for grade items within a category with either Mean of grades (with extra credits) or Sum of grades aggregation type.)
Elsewhere on moodle.org, I came across an interesting discussion: Plugin, module, block – what’s the difference? Perhaps we’ll get around to changing the name of the Modules and Plugins database one day!
