Testing and accountability programs can lead to some positive changes towards student performance. Here, Jones and Egley explore on whether Florida administrators thought that there was anything that could be done to improve the country's testing program in order to reduce or eliminate the types of concerns raised in George's study by conducting a…

Test equivalence can be evaluated in terms of four aspects: psychometric, behavioral, experiential, and individual differences (i.e., relativity of equivalence) (Honaker, 1988). This study examined the psychometric properties of the Attitude Towards Computerized Assessment Scale (ATCAS) designed to assess one of these criteria, namely,…

This paper deals with optimal partitioning of limited testing time in order to achieve maximum total test score. Nonlinear optimization theory was used to analyze this problem. A general case using a generic item response model is first presented. A special case that applies a response time model proposed by Wang and Hanson (2005) is also…

This paper presents a synthesis of what is currently known about the nature and development of scientific reasoning and why it plays a central role in acquiring scientific literacy. Science is viewed as a hypothetico-deductive (HD) enterprise engaging in the generation and test of alternative explanations. Explanation generation and test requires…

In this report, the circularly symmetric model is extended to the point where the symmetries are exhibited in blocks. In addition, it is shown how maximum likelihood estimators (MLEs) and likelihood ratio tests (LRTs) can be obtained. The circularly symmetric model is reviewed and it is shown how MLEs and LRTs can be obtained by reducing the model…

The Rasch model of latent trait test theory is extended to multiple choice questionnaires. The statistical development and logic of the extension is presented and implications of the extension are discussed. (JKS)

Prison inmates (N=565) classified as underachievers or adequate readers were administered the Wechsler Adult Intelligence Scale-Revised. Analysis of recategorized WAIS-R scores suggested that, as a group, the underachieving readers exhibited a pattern different from that of genetic dyslexic Ss and different from that of reading and learning…

An examination of statistical weaknesses and test limitations of performance contracting. (Author)

College Ss were twice administered both on IQ test and a test opinion scale in counterbalanced orders. The Ss received differential feedback before the second administration. Feedback significantly affected subsequent retest IQ test scores and opinion scale scores. It was concluded that when the testing is viewed as a complex interaction of…
