Glossary

• A ‘screencast’ is a digital recording of the evolving image on the screen during a lecture presentation synchronised with the speaker’s audio narration.

• We use the term ‘vignette’ to refer to a short segment of a screencast covering a critical concept which may be augmented by an interactive component introduced during the editing process.

Open Educational Resources• There are issues with Screencasts:

– ‘Attractiveness’– Copyright

• Vignettes– Distinct from lecture capture– Desirable?– Transferrable?

• Interactive element (SCORM)“Sharable Content Object Reference Model (SCORM) is a collection of standards and specifications for web-based e-learning. It defines communications between client side content and a host system called the run-time environment, which is commonly supported by a learning management system. SCORM also defines how content may be packaged into a transferable ZIP file called "Package Interchange Format". “Wikipedia 23/5/11

• Jorum– Vignettes will be deposited with Jorum as SCORM content and as mp4 files (which will

lack the interactivity).

EvaluationQuestionnaire Focus groups

• “Needs a screencast for all lectures - sometimes some can be missed out, and means may forget to revise that section”

• “Vignettes definitely helpful, condensed a lot of work into a small time - but more as a recap than learning”

Evaluation

EvaluationQuestionnaire Comments

• “just use media player, not java”• “could not access it”• “Couldn't use the viginettes in

Google Chrome, but I could in I.E.” • “I preferred the video player

compared to the screen casts. The quiz pop-up is an excellent idea. But sometimes it would repeat the question a second time when closed the box.”

• “Some did not load. However I am not sure whether this is a blackboard problem or is due to my laptop being rubbish.”
