Item Difficulty Modeling Using Fine-tuned Small and Large Language Models
This study investigates methods for item difficulty modeling in large-scale assessments using both small and large language models (LLMs). We introduce novel data augmentation strategies, including augmentation on the fly and distribution balancing, that surpass benchmark performances, demonstrating their effectiveness in mitigating data imbalance and improving model performance. Our results showed that fine-tuned small language models (SLMs) suc…
Further Clarification Regarding Validity and Education
opportunity to present our ideas on validity, a topic that we consider to be of utmost importance (A Suggested Change in Terminology and Emphasis Regarding Validity and Education, this issue, pp. 437-448). We would also like to thank the distinguished discussants-Susan E. Embretson, Joanna S. Gorin, Robert J. Mislevy, Pamela A. Moss, and Stephen G. Sireci-for their thoughtful and challenging comments (also in this issue of the journal) regarding …
A Suggested Change in Terminology and Emphasis Regarding Validity and Education
This article raises a number of questions about the current unified theory of test validity that has construct validity at its center. The authors suggest a different way of conceptualizing the problem of establishing validity by considering whether the focus of the investigation of a test is internal to the test itself or focuses on constructs and relationships that are external to the test. They also consider whether the perspective on the test…
Measurement Training for School Personnel Recommendations and Reality
Using evidence from a national survey and earlier literature, Schafer and Lissitz note that the time spent by teachers in assessment activities is not reflected in their evaluation skills nor in their prep aration programs. Prospective teachers receive limited preparation in assess ment procedures despite the existence of well-developed recommendations from professional groups vis-a-vis as sessment objectives for preprofessional training. The aut…

Limitations of Coefficient Alpha as an Index of Test Unidimensionality1
Confusion in the literature between the concepts of internal consistency and homogeneity has led to a misuse of coefficient alpha as an index of item homogeneity. Coefficient alpha is actually a complexly determined test statistic, item homogeneity only being one influence on its magnitude. The related statistic, the average intercorrelation, has similar difficulties. Several indices of item homogeneity derived from the model of common factor ana…
An Examination Of Some Factors Related To Using Different Minkowski Models In Non-Metric Multidimensional Scaling
Great interest in non-metric multidimensional scaling has resulted in a number of computer programs to derive solutions. This study examined the effect upon stress of data generated under five metrics and recovered under all five metrics. MDSCAL-5M. TORSCA-9, and POLYCON-II were used to analyse these data. POLYCON-II was the most accurate, although none of the programs was highly successful. In most cases recovery with the Euclidian metric provid…
A Study of the Effect of the Violation of the Assumption of Independent Sampling Upon the Type I Error Rate of the Two-Group t-Test
This paper describes some of the situations in which a psychologist is likely to violate the assumption of independent errors. A Monte-Carlo study of the effects of this violation is then described. A number of examples of different kinds and degrees of dependency are included along with a table that gives the effect of the dependency upon the shape of the test statistic's distribution. The results of this study demonstrate that this assumption i…
The Utility of Homogeneous Subgroups and Individual Information in Prediction
A number of behavioral research studies have employed subgroups of subjects for prediction. In using subgroups for predictive purposes, a key assumption is often overlooked, i.e., at least one of the grouping or predictor dimensions affects the relationships between the other grouping dimensions and the criteria. The purposes of the present study were (a) to emphasize this commonly overlooked assumption and (b) to examine empirically the utility …
A Generalized Classification Technique Using Interval, Ordinal, and Nominal Variables
Moderator Subgroups and Bayesian m -Group Regression
In our initial paper (Lissitz & Schoenfeldt, 1974), we compared the effectiveness of five moderator subgroup models, including two least square procedures, two probability weighting (semi-Bayesian) methods, and the Bayesian m-group regression method (Novick, Jackson, Thayer, & Cole, 1972), in predicting college grade point average. It was found that the semiBayesian, the Bayesian, and within group least squares procedures offered no improvement o…

The Selection of Independent Variables and Prior Probabilities as a Factor Influencing the Accuracy of Classifying Individuals to Existing Groups
This paper first examines some of the suggestions made by Lohnes and Gribbons (1970) for improving the hit rate of multiple discriminant classification analysis. Alternative to their ideas are advanced and the effect upon hit rate is determined. It is found that an improvement, over their best hit rate, of greater than 26% can be achieved by adopting the ideas proposed by this paper. These involve a more careful selection of the variables and the…
