Blocks: Blur Names
The Blur Names block is created by Brendan Lalor, and released for all.
WHY: It helps protect student privacy, that FERPA-compliance might not dampen
our Moodle spirit.
WHAT: The Blur Names block helps conceal information that might otherwise
reveal the identities of students when faculty are displaying Moodle courses
to each other.
HOW: The presence of this block on gradebook and some other pages will blur
the names, email addresses, and images of students - e.g., in both the Grader
and User Reports; and it will do the same for names in Moodle core's Forum,
and in the Choice module, as well. This protection of student privacy allows
for more FERPA-friendly sharing among faculty.
Take whatever block-placement measures are appropriate in your situation to
ensure that the block is loaded on the relevant pages. For the simplest
cases, when you want to use it, add it to all pages in the left column (so
that it's loaded even when there is no column on the right). This is not a
one-size-fits-all strategy; so adapt it!
1. The block will not presently blur names in tooltips, which appear
when hovering over gradebook cells.
2. The block has not been designed to blur names in modules beyond those
listed: Choice, Forum, and in the Gradebook.
3. The block has not been tested for Moodle releases prior to 2.6. However
there's nothing too snazzy in it; so it should work with earlier releases
as long as they feature the relevant CSS class and ID names.
SOLICITATIONS: If you know a CSS-method for blurring the names in tooltips
that appear while hover over gradebook cells, please share it with me.
to honor requests for CSS-based extensions. Drop me a note at
