E-learning: Integrating Media and Interactivity
Incorporating audio
The
power of audio may often be overlooked, but the combination of written
and spoken words does have a big impact on recall and retention. To
bring audio into your course with Trainersoft simply means dropping the
clip onto the screen and setting its controls. The hard part is
determining where to use audio, and knowing how much is too much.
Audio, just like other media files, requires good bandwidth if you're
producing a Web-based program. This screen from Trainersoft 7 shows the
media controls you can set when incorporating audio into your program.

Incorporating video
A paper by Rachel Ellis and Mark Childs, published in the Journal of Educational Media in 1999, discussed the The Broadnet Project,
which was a study on the effectiveness of video as a learning tool in
online multimedia modules. Their conclusions and recommendations based
on the analysis of comments and perceptions of the trainees and the
producers were:
- Use video stories to put the subject into its context of use.
- Use video clips followed by questions to encourage active participation from trainees and build on existing knowledge.
- Ensure that these clips have the information required to answer the questions.
- Limit the length of talking head video clips and use them to elaborate on specific points.
For example, going back to our human resources manager example, the interview session could include three different choices for questions. When the student makes a selection, the video then plays out that scenario. They could progress until they chose incorrectly and had to face the consequences.
By relating to characters on the screen and being able to control their "destinies," students can learn from mistakes that would be too costly to make in the real world.
Trainersoft supports streaming media, which allows the student to see the video (or hear the audio) immediately. Rather than waiting for the complete file to download, the student hears it as it is "streamed" to his or her computer. This only applies to Web or intranet-based training. There are, however, hybrid possibilities that could include links to the Internet for streaming media or other training media. This might be beneficial if that portion of the training is likely to change and need updates frequently. By putting that portion of the training on the Web, updating the files is easier than recreating and distributing new CD-ROMs.
