Definition

Rep IV is the name for a series of tools for repertory grid technique (RepGrid) and visual syntactic structures used for representing construct networks (RepNet).

As of feb 2009 there are three versions according to the official Rep IV (RepGrid, SocioGrids, WebGrid & RepNet) page:

Personal Version 1.11

This “provides simplified versions of RepGrid and RepNet that are freely available for personal (non-commercial) use. It can elicit and analyze single grids with up to 15 elements and 15 constructs, and nets having a syntax from the set provided.”

Research Version 1.12

This provides the full versions of RepGrid, SocioGrids and RepNet for professional use (commercial)

Web Version 1.12

This extends the Research version with web server capabilities supporting WebGrid-style grid elicitation and analysis through web browsers.

A functional test version is available on the Knowledge Science Group Server, University of Calgary. Daniel K. Schneider used both WebGrid III and WebGrid IV to generated the examples discussed in Repertory_grid_technique#Analysis_techniques repertory grid analysis techniques

Creating a Grid

Step 1 - Create a new Grid

• Click on "New" and fill in the form

Tips

• Name should be the name of the participant (E.g. Daniel). It will show in the elicitation dialog.
• The same principle is true for "Purpose". E.g. the participant will see "Daniel is considering TECFA's on-line environments for ..."
• You must choose a scale, e.g. 5 points (negative numbers are not allowed, max. is 9).
• It's a good idea to change terminology, so that users can understand what you mean, e.g. to study representations people have of our (TECFA's) online environments that we currently used, we used:
  • system for element
  • aspect for construct

.... The rest should be obvious

Step 2 - Elicit elements and constructs

You also could administer an already made grid of course ...

Click on the Scripts tab and click Elicit Grid. The system now will elicit elements and constructs with the classical triadic method until it suggest that sufficient constructs have been entered to discriminate between all elements (no 2 elements should be the same) and that there are sufficient elements to discriminate constructs (no 2 constructs should be same).

At any point you also can add manually and element or a construct by clicking on the "Elements" or the "Constructs" panel.

Additional tips

To delete an element or a construct: select the line in the "Elements" or "Constructs" tag then hit BACKSPACE (the DEL key will not work not the "Delete" item in the "Edit menu".

Discussion

The personal edition of Griv IV has some missing features that a researcher might need, but also some interesting capabilities that are not found in other systems.

Ergonomics

At least on Win Vista it is not easy to see the cursor and where exactly one should click. This may be a problem with some users.

Break construct match

An interesting feature of this system is "break construct match" warning and "dialog options". E.g. at some point in the eliciation process, you will get this kind of warning:

Break construct match

The system is telling the participant that two constructs (systems in our case) are nearly the same, i.e. that they they discrimiate very little among elements (aspects in our case). It then prompts use to look for a system that has different combination on the scale, e.g in our case a system made for pedagogy and that also favors and open share space. We could for instance add a system like Knowledge Space (but we don't use if for real at TECFA).

On a side note, Daniel K. Schneider simply would like to add that indeed pedagogical platforms are deficient in more than one aspect and systems made for other purposes share many aspect since they are often made to support a community.

Break element march

In the same way, if two elements are too close, RepGrid IV will ask for another construct that might separate them. E.g. in our case it found Dokeos and Blackboard to be very similar systems:

Break element match

The feature I found was simple: One is commercial and the other is free and open source.
