With the rise and rise of the computer as a teaching tool, elegant and effective ways of sharing and explaining on-screen activity are of rapidly growing interest throughout the education and training community. Everything from software demonstration and training, through web tours and walkthroughs, to pre-recorded presentations can be delivered as screencasts.

In our new Screencasting Workflow advice document we take a detailed look at all stages of the screencast production and delivery workflow, with explanations and demonstrations of techniques, tips on software and hardware selection and use, planning, performance and more. Designed as a thorough introduction to screencast production, this new resource also features several embedded screencasts which explore different areas of the screencast lifecycle, and numerous links to further documents and resources.

Invaluable for the beginner wanting an overview of the process, as much as the experienced screencaster after advice on more advanced techniques, this is a comprehensive introduction to the technical business of broadcasting your screen.

Web fonts let you use a far greater selection of typefaces on web pages. Although it has always been possible to put any typeface on the web by included it in an image, web fonts make your text selectable, scalable, editable, searchable and accessible.

Following the publication of our introductory guide, Google announced its new Google Font Directory and Google Font API. This allows anyone to use their collection of open source fonts freely on the web by adding a couple of lines of HTML to their web page.

Here is an example of text written using the Lobster font

The above line should appear in the Lobster font available from Google Font Directory. We have set Arial as the fallback font for browsers that may not support web fonts.

For more on web fonts have a look at our Introduction to Fonts and Typefaces.

The film not only showcases what we do but also offers an example of how information can be presented in an innovative way to engage a viewer, in this case through the use of animation (JISC Digital Media benefit from in-house expertise in video production and animation).

The short film 'Robotz' was the result and you can watch it here:

JISC Digital Media - Robotz Promotional Film from JISC Digital Media on Vimeo.

The principles embodied in the film can be applied to any informational media. Powerpoint, VLE design or even selecting video clips to illustrate 'real world' lectures might all benefit from the approach we took when making 'Robotz'.

You can read more about the making of 'Robotz' in our latest Intermedia newsletter.
