 Let's explore groupings. Now firstly through the eyes of an admin on the front page, side administration block, we need to go to Miscellaneous Experimental. This is as of Moodle 1.9.7. It's not enabled by default, but we first need to enable groupings. So groupings are clusters of groups and naturally we use groups to micromanage learners in a given course context. So let's just step into a sandpit and we'll create some groups. So we'll call this group, let's say Sydney, Sydney group and we'll create the Melbourne group. So the number in brackets alongside the group name indicates the number of members in those said groups. None at the minute. Okay so we'll say for Melbourne we will add student, that particular student to the said group, factor groups and we'll do the same thing here. For the Sydney group we'll add the second student to that group. So in fact just organize one student in each of those respective groups. We've got a groupings. Let's create some groupings again. Generally it's a one-to-many relationship here, one grouping and a cluster of groups, but in this case we're just mapping one group to a single grouping, the purpose of what we're trying to achieve. So we'll call this the Melbourne grouping. We add another grouping, Sydney grouping. Okay so we edit this particular grouping. We want to for the Melbourne grouping add Melbourne group, factor groupings. We'll do the same thing for Sydney, mapping the Sydney group to the Sydney grouping. So where this all starts to make sense is we go back to the course page, we're editing on, let's add a resource, we'll link to a file. Okay we'll look at the file name. So we'll just say, what's this? It's just a file resource. You'd call it something perhaps more descriptive. Now we'll upload that file. So quickly browse for it. Okay so this could be a document, a presentation, a piece of media, anything that's likely to have been prepared earlier. So we select that where groups and groupings comes into place down here toward the bottom in this page where we say available for group members only and we might say that okay well this is only available to the Sydney group for example. Okay so we say return to course. So in theory we can see there in brackets alongside that resource it's only available to the Sydney grouping and you could in fact test that as a proof of concept if you wanted. Okay if we go to the participant list and we can go okay we've got a Melbourne student here who's in fact enrolled in the Melbourne group and belongs to the Melbourne grouping, log in as them and in theory they shouldn't see that resource and in fact they don't.
