Just made these screencast tutorials for the team I'm working with as eLearning coordinator and thought I would pass them along here on the blog for those in my PLN who are starting out with Moodle and want some tips and tricks...
The idea here is to create a simple menu at the top of your Moodle course page that allows your learners to click and have only the relevant unit or cluster appear on the page. Essentially, this removes the 'scroll of death' issue if you find your learners are having to wade down through dozens of units to find something.
If you've found a better way to do/present this, please, by all means let me know (and even better: screencast how/why to do it!).
