The assignment task is to develop and analyse a test (exam) with focus on validity, reliability and fairness. The assignment should include:
1- Explanation and justification for choice of measurement (classical test theory) model and use of the model for construction of a scale and statistical analysis of the items ( I have done that already) have a look at it and kindly edit it
2- Results from the analysis, including data and comments.
3- An overall discussion and recommendations for further development of the test
4- Item distribution across construct
5- Validity ( internal and external)
6- and reliability (internal consistency, split half) of test
7- Limitations of the test( why it a good\bad test) and weaknesses and how to improve it ( kindly reflect on that
8- true score model X =T+E E is the error of measurement ( I have done that )
9- the relation between item difficulty and student ability should be clarified and well defined
10- The following books would help : Constructing measures: an Item response modeling approach by Mark Willson, 2005, however the book discusses Rasch model for measurement while we chosen the classical test model (true score model)
11- The other book which may help its title is: Measuring up: What educational testing really tells us By: Daniel Koretz
