This video was recorded at Complex Objects Visualization Workshop, Koper 2005. A graph is a mathematical structure that is sometimes hard to separate from its visualization. An important branch of graph theory studies graph drawing problems. Recently a mathematical approach to graph visualization has been developed under the name of "graph representations". In this tutorial we present an outline of the theory of graph representations.
Type of Material:
Presentation
Recommended Uses:
This is a lecture. It can be used as a self-paced and for homework as well.
Technical Requirements:
Browser. However - does not run on all browsers. It did not run on chrome -- but ran fine on firefox on my Mac Computer. Requires Adobe Flash.
Identify Major Learning Goals:
To learn about how graphs can be represented. As per the authors:

Target Student Population:
College General Ed, College Lower Division, College Upper Division
Prerequisite Knowledge or Skills:
Knowledge of graphs and Math.
Content Quality
Rating:
Strengths:
- The contents are fine and it gives the learners good explanation of the representation of the graphs.
Concerns:
Not suitable for general population as it expects mathematical maturity.
No exercises to help check understanding. Not interactive in nature (i.e. no active learning)
Video has not been edited in any way. It is straight from a class (and includes unnecessary segments and distractions).
Potential Effectiveness as a Teaching Tool
Rating:
Strengths:
- The objectives of the video lecture are clear to learners.
- Slides are given side-by-side, so the content and the video are synchorized appropriately.
- It can provide an overview.
Concerns:
Lectures can be construed as boring. Thanfully it is not too long and it is also indexed for easy access to a section.
Although it is a good presentation - it is not clear how effective it will be as a learning material --- mainly because it requires passive learning.
Ease of Use for Both Students and Faculty
Rating:
Strengths:
Nice layout.
Video on left side. Slides on left side.
Video is broken into segments. Captions can be clicked to go directly to some part of the video.
There is a section for leaving comments.
Concerns:
The great problem of the video is developed based on Flash which is regarded as obsolete, so many users can not view it in the common browsers nowadays.
