Excellent choices made for topics and well-chosen links to websites. I am impressed with the layout of the work. I am under the impression that your work is still under construction but i think overall it is looking quite good. --Ksthill 07:45, 16 March 2007 (CET)


Yes it is. What do you think of the objectives - do the general and specific match?--Augustmoon 08:09, 16 March 2007 (CET)

Reliability and Validity

I think that the definitions of the above neeed to be more focused.The statement "Reliability is related to the consistency of assessment scores over time,and between and among raters... and Validity is related to..." doesn't give the reader a clear idea of the meaning of the terms. You are talking about 2 things in the first instance. 1) the reliability of the test/instrument and 2) Inter-rater Reliability. Reliablity speaks to the issue of consistency and repeatability. Does the test/measure/instrument consistently, over time, produce the same kind of results. Inter-rater reliablity is about the consistency of raters/assessors in arriving at similar ratings/assessments based of course on (the design?? of) the test/ instrument. Definition: Reliability: The extent to which a measurement instrument yields consistent, stable, and uniform results over repeated observations or measurements under the same conditions each time. Issues of Internal consistency re: design of the instrument also impacts reliability. Validity on the other hand speaks to whether the test/instrument tests what it is intended to. There are concerns that relate to face- validity, content valildity etc. Whilst the bullets under the two terms attempt to provide more fodder, what may be more worthwile may be bullets that speak to the characteristics of a reliable test/instrument and that of a valid test/instrument--Ainsworthovid 06:56, 25 March 2007 (CEST)
