TITLE

CONTENT

How to be seated

Demonstrates how to achieve a seating arrangment that allows all the participants to be seen by the camera

Confused lecturer

This video shows that even highly experiences lecturers are liable to panic in the event of technical problems

Oral exams over video conference

An example of how an oral exam can be held by video conference

Codec video inputs

Demonstrates how to connect different type of peripherals (external camera, VCR, laptop, document camera etc.) to the video inputs on the codec

Using a document camera in a video conference

Shows different ways of using a document camera in a video conference

The document camera: a brief history

A brief historical introduction to the document camera - from the old overhead projector to an advanced document camera

Video conferencing lectures: how not to do it

In this sequence we invite the viewer to watch through a thoroughly bad lecture, and write down all the mistakes that the lecturer does in front of the camera

What went wrong?

This video highlights and discusses the lecturer's mistakes in the sequence above

Giving a lecture by videoconference, part 2: still room for improvement

The technical side of the video conference works flawlessly, but still no interaction

Giving a lecture by videoconference, part 3: how to do it

A varied and structured lecture which is also interactive

The importance of eye contact

This video stresses the sheer importance of looking into the camera to maintain eye contact with the other party

How to place the camera relative to the screen seen by the lecturer

Demonstrates how to place the camera close to the screen as to maintain eye contact with the camera

How to place the camera relative to the screen seen by the students

Demonstrates how a camera mounted in a classroom should be positioned to allow eye contact with the students

Pen colours on flipovers: which color works better?

Some pen colours (such as light green) are barely visible when filming a flipover

Pen colours on whiteboards: which color works better?

Some pen colours (such as light green) are barely visible when filming a whiteboard

Placing and orienting a microphone

How to orient the microphone relative to the speaker as to achieve a consistent sound level

Using wireless microphones

How to use wireless microphones to avoid the problems of table-top microphones

Failure to use camera presets

This video demonstrates the sheer chaos of a video lecture that doesn't use camera presets

Correctly using camera presets

Shows how to use camera presets to eliminate time-consuming adjustmests of the camera

Inputs and outputs on a codec

A quick overview of the different connectors and cables used to attach peripherals to a codec

Monitor views: Continuous presence

Shows a screen layout often used in e.g. collaborative meetings, where all participants are visible simultanously

Monitor views: Voice-activated camera switching

A screen layout where the last person to speak in shown in full screen for the other participants

Request floor

Some types of videoconferencing equipment enables any participant to "request floor", ie. to request to be shown in full screen for the other participants to see

Assign floor

Demonstrates that the person controlling the conference can at any time "assign floor" to a participant, ie. show the participant in full screen for the others to see

About digital whiteboards

Gives an introduction to pressure-sensitive digital whiteboards

Normal whiteboards equipped with sensors

Demonstrates the use of normal whiteboards equipped with ultrasonic or infrared sensors to transfer whiteboard notes to a computer

Writing text on a pressure-sensitive whiteboard

Demonstrates various tools for writing text on a pressure-sensitive whiteboard

Drawing geometric shapes on a digital whiteboard

This video demonstrates how the digital whiteboard's built-in functions can be used to draw geometric shapes

Importing elements into a digital whiteboard

Shows how to import images and internet pages into a digital whiteboard document

Exporting documents from a digital whiteboard

Demonstrates how to export documents from a digital whiteboard into a format suitable for publishing on the web

Using the gallery

Most digital whiteboards come with a collection of images and clipart called a gallery. This video suggest some ways to use the gallery in a teaching enviroment

Filming a person in front of a digital whiteboard

This video highlights the problem of filming a person in front of an illuminated surface, as the subject will become very dark. We suggest a work-around solution for this

A sample video lecture

Here we join in on a video lecture in physics

A practical example of interaction in a video lecture

Shows a concrete way of achieving interaction in a video lecture. The participants are given an assignment by the lecturer, and present their answer on a flipover

Intolerable noise levels

An example of how noise levels can reach intolerable heights during a video conference, due to unwanted chatting, paper shuffling etc.

Using digital whiteboards to perform interactive calculations

A demonstration of how a digital whiteboard can be used to perform interactive calculation in mathematics. Relevant parameters are entered into a web applet, which performs the calculations and displays the result in the form of a 3D graph. The graph can be rotated, zoomed in on etc.

Streaming physics video 1: The atmospheric pressure causes an implosion

This video gives an example on how streaming video and text elements can be combined to give a multimedia-rich learning experience. In this video the atmospheric pressure is used to crush a soda can

Streaming physics video 2: Adiabatic processes

Another example of using streaming video in teaching physics. This video gives some everyday examples of adiabatic processes (i.e. processes in which there is no heat loss, for example in a combustion engine)

Streaming physics video 3: Radioactivity

A streaming physics video which studies the effects of radioactivity, including the origin of radioactivity, the ionizing property of radiation and how to measure radioactive half-life

Designing a classroom to accomodate the use of digital whiteboards

In this video we join in on a physics lecture in which the lecturer uses a digital whiteboard. We also look at how the classroom is designed to accomodate the use of a digital whiteboard (e.g. how to position video projectors)
