CHC COG-ACH research synthesis project important update 1-8-09

[Double click on image to enlarge]

I'm pleased to announce another update and major revision to the the Cattell - Horn - Carroll (CHC) Cognitive Abilities-Achievement Research Synthesis project, a project first described in a prior post. This is a work "in progress". The purpose of this project is to systematically synthesize the key Cattell-Horn- Carroll (CHC) theory of cognitive abilities designed research studies that have investigated the relations between broad and narrow CHC abilities and school achievement.

The status of the project can be accessed via a clickable MindMap visual-graphic navigational tool (similar to the image above...but "active" and "dyanamic") or via the more traditional web page outline navigational method. You can toggle back and forth between the different navigation methods via the options in the upper right hand corner of the respective home web page.

Feedback is appreciated. I request that feedback be funneled to either the CHC and/or NASP professional listservs, mechanisms that provide for a more dynamic give-and-take exchange of ideas, thoughts, reactions, criticisms, suggestions, etc.

The most significant new revisions/additions/changes are in branches 4 and 6. A subtopic under branch 4 (studies included in the review) now includes the references of all the 19 studies reviewed AND URL links to the actual studies. The most significant revision is the addition of branch 6, which provides access to four summary charts/figures (sample figure is above) that attempt to synthesize the massive amount of coded information in the tabular summary tables (branch 5).

Barb Wendling and I are now going to commence interpretation of these charts/figures (and the tabular summary tables). I wish I had my interpretation, caveats, explanations of surprising findings, etc. written today, but it is going to take some time. To faciliate the process I would LOVE feedback from CHC experts on insights they may glean from a review of the four summary figures. Please discuss any hypotheses, insights, etc. on the CHC and/or NASP listservs.

This project is evolving into a manuscript to be submitted for publication and will also serve as the basis of my mini-skills workshop at NASP re: this research project.
