YouTube screencast of RBL session 5 deals with distance travelled, the planning and milestones for resource based learning projects, the way I intend to use progress reviews to support participants in carrying out their project plans, and some quick hints on a piece of writing that is due in shortly. The screencast took two takes of about 7 or 8 minutes to produce. The visuals are simply the slides I will use in the f2f session anyway.

9 minutes and 46 seconds on basic probability, including the probability scale, expected frequencies, mutually exclusive and independent events, possibility space diagrams and even a without replacement problem. All aimed at a GCSE Intermediate group. The .mov file was produced by ‘presenting’ a PowerPoint while speaking a commentary recorded using iShowU screen cam software. YouTube provide the hosting and convert the .mov to a Flash movie.

The screen design screencast MOV was uploaded to YouTube. I’m now waiting for it to be ‘processed’ so that the video can be watched.
