10 minutes on the max/min median and quartiles

6 minutes and 43 seconds on how to cancel down a fraction to its lowest terms. I’d rather describe that as ‘remove all the common factors from a fraction’. Produced using the NCH Debut video capture software, and edited in Windows Movie Maker. Notes on how to do all this coming soon.

2 minutes and 28 seconds on multiplying fractions. Recorded as a quick reminder for students on a return to study course.

Produced on my College issue laptop using the free version of the NCH Debut screen and Webcam capture software, and using the cheapo USB microphone (Logitech and Belkin sell the same oem device). Attempts to [...]

Slideshare from an OpenOffice Impress presentation on the basics of fractions. Based on an idea from Malcolm C. It worked for his students so I’ll try it out with my Level 1 Adult Numeracy students.

A couple of worksheets coming as well…. You can download a PDF of [...]

Iâ€™m trying a visual way of introducing those reverse percentage story problems that go like this: â€œFred has had a pay rise of 10% and now earns Â£22000. What were his wages before the pay riseâ€.

Contrast, repetition, alignment, proximity

Ratio and proportion problems introduced visually

8 minutes on how to link slides together and build a menu in PowerPoint.

What do the built in microphones sound like? Not too bad, a bit low on the treble but reasonable sensitivity. High pass filter in Audacity sorted it.

Slideshare deck shows step by step solutions.

PowerPoint gets a sound track and is published to YouTube and TeacherTube. TeacherTube has problems with sound on MOVs made with iShowU version 1.33

YouTubes on rectangle, parallelogram and triangle, and on circles and composite shapes

Multiplying terms helps students to revise indices and directed numbers.

I guess this is a podcast with visuals.

YouTube video about tree diagrams in GCSE Probability. Me talking with illustrations provided by a PowerPoint presentation. I scripted the speech but then extemporised at various points – and managed this in two complete takes.

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.

A screencast made on Mac OS X using iShowU and Video2SWF to produce a flash movie with synchronised sound.

More audio learning: five minutes on prime numbers and finding prime factors. Students need something to write on and with unless they have excellent short term memory!

If 5 kilos of potatoes cost Â£2.60, how much will 7 kilos cost? These are simple everyday problems but spending a little time on them lays the foundation for percentages and ratios nicely. This podcast works through some easy examples.

Listen to WMA files direct from the Olympus WS-200s digital voice recorder. One with the internal microphones and one with an external dynamic microphone.

4 minutes and 15 seconds on what a Virtual Learning Environment can do for you

An audio lesson on easy areas with a single one side sheet of diagrams. This will be used by at least one student who can’t make the lesson because of shift pattern change.
