Guidelines for multimedia resources creation

Here is another helpful summary, relevant to those making and using on-line instructional  videos or lectures.  There are several underlining principles of using multimedia resources, based on theories of how the human brain processes a combination of verbal and visual information: 1)It is better to provide explanations in two forms of information rather than one  e.g. a film with corresponding  verbal explanation is better than just a visual aid; 2) Multimedia explanations should include words in verbal rather than written form e.g. try watching a subtitled film; 3) Coherent summary  highlighting key words/visuals  is better than detailed explanations.

All common sense really, but neatly put together.

Useful information on e-learning effectiveness

Here  is   the summary  of  a study comparing student satisfaction and formal test results after using four different types of instruction:  traditional classroom, on-line instruction without video, on-line instruction with video, and on-line instruction with interactive video  (video organised in small chunks that are well-indexed, and easily manipulated).  All groups that used on-line instruction reported higher satisfaction than the group with traditional classroom instruction.  The students using on-line instruction without video and those using on-line instruction with linear video scored equal satisfaction.   The interactive video group reported higher satisfaction.  The test scores (learning outcome) of the group using the interactive video were higher than those of  the other three groups.

Does this justify the time investment that making interactive videos require?

How to create good on-line videos – teaching and professional fellowship project findings

Staff views.  LCF technical staff focus group reviewed a number of videos (available from the LCF BlackBoard, PROCESSARTS, and an on-line video produced by Derby University) looking at their reuse values.  All videos were focused on basic sewing machine preparation and use, but differed in production style.  Several initial recommendations emerged:

– introduce a graphic overlay highlighting key points on the screen where  applicable;

– prepare good scripts, including some contextual information;

– consider  voiceover (to prevent the viewer from being distracted by the presenter) .

Ideas from the Open Source community for video learning resources

Here is a link to an Open Source Community about CNC router machines:

definition of CNC; “A machine tool that uses programs to automatically execute a series of machining operations.” (http://www.toolingu.com/definition-900130-12155-cnc-machine.html)

Not only is it an interesting layout of a website/ blog community, it also offers some interesting CAD examples (in the grey boxes) which could be learning videos.
