Using videoconferencing in the classroom

An interesting article about incorporating guest speakers into classrooms using Skype or a virtual classroom tool (Adobe Connect) and a new Skype service for educators to trade tips and tricks, called "Skype in the classroom."

Putting Defence lecture material on-line

Peter Hamilton (Defence and Systems Institute) writes about his approach to e-learning by using online presentations to replace the lectures.

I had the job of creating an Associate degree in Engineering (Defence Systems) program where all students would be working in industry and needed flexibility for learning. The students were more mature and had worked in manufacturing engineering roles, primarily as technical officers, and needed to retrain for work in companies that service the growing Defence industry.

Below is a presentation that describes the project (UniSA staff can view the web sites linked within the presentation).

Associate Degree in Engineering (Defence Systems) e-learning project

One of the strategies used was a 'lecture capture' technique where we made short recordings of the topics given by our course experts that could be accessed online 24x7. We had financial support from the federal government to implement the program and create the resources.

To make this happen, I purchased 6 licenses for Adobe Presenter 7, the application software underlying the ‘In a Nutshells’, in about Sep/Oct 2008. It works as a PowerPoint add-in that publishes that allows ‘narrated PowerPoint presentations’ to be created and saved on a special server in ISTS. The process of up-loading narrated presentations to the Server is centrally controlled by me.

The tool is relatively easy to use with most lecturers being able to master the tool in under 30 minutes. Narrated presentations have been created in a number of ways depending on the preferences of the lecturer:

1. Lecturers use an existing PowerPoint presentation for which they have prepared a script or, sometimes, good notes. Lecturers then record the script using the Presenter 7 tool. The script becomes the ‘Notes’ component of the narrated presentation.


2. Lecturers use an existing PowerPoint presentation but without a script. Using the Presenter 7 tool they record the narration for each slide speaking ‘off-the-cuff’, prompted by the slide content. The sound file is then transcribed into a Word document by a professional transcriber; is edited by the lecturer to eliminate ums and arghs; and forms the ‘Notes’ component of the narrated presentation.


3. Lecturers present a PowerPoint based lecture in the normal face-to-face fashion. The lecture is recorded using a digital recorder. The sound files are transcribed in the same way as above. Using Presenter 7, the sound files are uploaded to match the PowerPoint slides while the transcribed and edited sound file is used as the ‘Notes’ component of the narrated presentation. This is a quite labour intensive process.

These recordings have been well received by students both on-line and on-campus as they can revisit them as often as they like. We have sometimes just played them as a lecture and still the students appreciated them as they were very clear.

We need to be mindful of the length of the recordings as there is only a certain amount of time that someone will look at their screen to watch a recording. Our average lecture length is about 20-30 minutes, some a little longer, others a little shorter. For a lecture, I consider about 30 minutes to be optimal.

Capturing lectures

When developing content for teaching in online courses, or providing extended flexibility for face-to-face or external students, many people consider the use of lecture capture techniques. Lecture capture could be as simple as making an audio recording of a lecture and slides/notes available online or can involve using sophistocated software programs that link together the voice, visuals and resources.

Educause put together a short document called the 7 things you should know about Lecture capture that describes what it is and considers the significance, implications and downsides.

One of our first podcasters at UniSA was Tim Sawyer in Medical Radiation - he prepared this short presentation about his approach to share with others in 2007 (6 minutes) as he was quite impressed with how much his students engaged with the recordings.

Currently we don't have any automated systems to do podcasting or lecture capture at UniSA - although last year we were close to getting Lectopia - an automated record and publish tool installed in lecture theatres - but for some reason it all faded away. If you want to make recordings you need to have access to your own (school's) recorder.

If you do want to try making audio recordings, Online advisers will set up "podcasting" environments for courses that students can subscribe to to receive lecture recordings to their ipod as soon as they are available. A manual upload of audio files and pdf documents (lecture notes) by the lecturer is required.

Our next blog post will be from Peter Hamilton from DASI who has used Adobe Presenter as his main lecture capture tool for courses in the Associate Degree in Engineering (Defence Systems).
