Blocks: AJAX Marking Block
Please note: This plugin is no longer supported for newer versions of Moodle, and I'm afraid I don't have the time to give it the full rewrite that it really needs. Sorry
The aim of this block is to avoid having to search through each of your courses to find out whether there is anything that needs marking.
When placed on the front page, it shows teachers how many pieces of work need to be attended to, broken down by course, or by cohort. The list then expands when clicked to show individual modules and students. When you click on a student, a pop-up opens, allowing the work to be marked and saved, then the block updates itself to show one less item in need of attention.
The block has been thoroughly tested on a copy of a large university database with >50,000 users and has been optimised so that it doesn't impact on DB performance at all.
Current status is that the development is paused (bug fixes only) whilst I work on other urgent projects. Once the Moodle logging 2.0 proposal in core is built and released, there will need to be a complete rewrite to make it maintainable for the future, but that is some way off.
If you want to stay current, follow @AJAX_Marking on twitter, which has general information about new features etc.
