Description of Grid

As a first grid I created it to see if it could determine which sports I like best, and see if it coincides with what I really think. I listed as my domain "sports" and as my context "sports I would like". I listed a number of different sports as the elements of my grid. The next section is where I specified the constructs to use for the grid. Here the program gives you a combination of three of the total number of elements and you are to choose what one is different from the other two and what the differences are, and then rate all the others on these attributes. When you click on the FOCUS button you are presented with a grid which groups together elements that are similar in nature.

Comment on Initial Impression

Initially I found WebGrid a little confusing as a whole and in particular deciphering between what was a construct and an element. Once you got going on it it and did a little reading on Personal Construct Psychology (PCP) the terminology became clearer. It was interesting to see the results the grids produced and how it decided that some of your constructs are virtually the same.

Part 2: Elicitation of Constructs on CPSC 547 Topics

Developing the Constructs

Coming up with the constructs for this grid was fairly difficult because the elements were at times hard to distinguish between and I found myself retrying the TRIAD button until I was able to figure out a distiguishing factor between the three elements. If WebGrid found two elements to be similar I would try to distinguish between theses two, to create a new contruct.

Description of the Grid

The grid was set up using elements based on the presentation topics of our computer science 547 class. The following constructs are the ones I chose to differentiate the topics:

These constructs differentiated the elements and a grouping of similar elements based on these is shown when FOCUS was pressed.

Comparison of the Grid

See the compare button on the WebGrid for the actual comparison to Dr.Gaines' constructs.

The relationship between our two sets of constructs seem to be, for the most part, in correspondence according to the 4-way classification of constructs given by Dr. Gaines and Dr. Shaw, although using different terminology for the same distinctions they match up closely.

Part 3: Elicitation of Constructs on Wide Area Broadband Networks

Description of Grid

Since I did part of the section on "Applications of Broadband Networks" I used this for the context of my final WebGrid. As the domain I chose Wide Area Networks. I chose six different Broadband applications as my elements for the grid, including such things as Distance Learning, Video On Demand, Medical Imaging, etc. The constructs I developed were as follows:

Analysis of Grid

The FOCUS graph shows relationships between the elements and the constructs I have chosen for my WebGrid. From the graph it is apparent that Recreational - Educational are related constructs and that Distance Learning - Video Conferencing are related elements.

The PrinCom graph shows the components anaylsis. It virtually shows the same type of theings as the FOCUS graph only in a different aspect, to show the relationship in a different form.
