The system describes, in order, the outcomes that students are expected to achieve in eight broad learning areas. The study has three aims. One, to create a scale for teacher receptivity to the use of Student Outcome Statements, based on eight orientations to receptivity: evaluative attitudes, behavior intentions, feelings towards Student Outcome Statements compared to the previous system, the benefits of the new system, support from significant others, alleviation of concerns, collaboration with other teachers, and involvement in decision-making. Two, to analyze the psychometric properties of the scale using the Extended Logistic Model of Rasch (Andrich, 1988; Rasch, 1960/1980) with the computer program RUMM (Andrich, Sheridan & Luo, 1997).

The four factors upon which the simulated data matrices varied were (a) the distribution of the scale values for the items (skewed or uniform), (b) the number of category response options (4 or 5), (c) the distribution of known trait levels (normal or skewed), and (d) the sample size (60, 125, 250, 500, or 1,000). Each condition was replicated 10 times resulting in 400 data matrices. Accurate item and trait parameter estimates were obtained for all sample sizes examined. As expected, sample size seemed to have little influence on the recovery of trait parameters but did influence item parameter recovery. The distribution of known trait levels did not seriously impact the item parameter recovery. It was concluded that Andrich's rating scale model allows for the use of considerably smaller calibration samples than are typically recommended for other polytomous IRT models.</p>","PeriodicalId":79673,"journal":{"name":"Journal of outcome measurement","volume":"3 2","pages":"176-99"},"PeriodicalIF":0.0,"publicationDate":"1999-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"21075949","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These results serve as validity evidence for the Rasch model procedure as a means for evaluating DIF in examinations. The conclusion is drawn that complex procedures are not required to generate interpretable results if relevant differences between the groups being compared are known.
