There is a degree of instability in any measurement, so that if it is repeated, it is possible that a different result may be obtained. Such instability, generally described as "measurement error", may affect the conclusions drawn from an investigation, and methods exist for allowing it. It is less widely known that different disciplines, and…

Although test anxiety is typically negatively related to performance on cognitive ability tests, little research has systematically investigated whether differences in test anxiety result in measurement bias on cognitive ability tests. The current paper uses a structural equation modeling technique to explicitly test for measurement bias due to…

Precision and generalizability for relative and absolute change scores were estimated by means of error/tolerance ratios and generalizability coefficients for 51 patients receiving 1 year of psychodynamic psychotherapy. These estimations involved 6 scale indicators and 3 raters. Practical suggestions are offered for the number of rates needed to…

The present study provides experimental data comparing emerging adults' attitudes toward dating and sibling violence in adolescence using a new methodology in which participants observe a violent interaction between adolescents. The reported amount of violence experienced in dating and sibling relationships among emerging adults is also compared.…

Shneidman's Psychological Pain Assessment Scale (PPAS; 1999) was administered to 88 psychiatric patients. Both current and worst-ever psychache were significantly higher in those patients judged by a psychiatrist, on the basis of a structured clinical interview, to be at risk of suicide. However, current and worst-ever psychache were not…

The authors describe the development and psychometric properties of the Korean Mood State Inventory (KMSI), which is designed to measure the mood states of Korean college students. Factor structure, concurrent validity, and internal consistency of the KMSI scores are reported. Implications, limitations, and recommendations for future research are…

Attributions of laziness, reflected in teacher comments such as "Just try harder and you will shine", may mask specific cognitive, learning, attentional or emotional problems that could explain low motivation in some children. This paper reports findings from an investigation of 20 children, aged 7 to 10 years, who were regarded as lazy…

"Teachers Teaching Teachers" ("T3") focuses on coaches' roles in the professional development of teachers. Each issue also explores the challenges and rewards that teacher leaders encounter. This issue includes: (1) Building Bridges: Data Help Instructional Coach Make Vital Connections with Teachers (Theresa Long); (2) NSDC Tool: Instructional…

This study investigated whether an intervention measurably contributed to the self-regulatory processes underlying undergraduate students' learning. The Rasch model was first applied to Dynamic and Active Learning Inventory Revised (DALI-R; Iran-Nejad & Chissom, 1992) data to examine the validity of inferences made from this instrument and to…

An important goal for California is that public high schools continue to make progress in closing the achievement gap between demographic groups and that students are prepared for postsecondary education. In early 2008 Commission staff started developing a composite measure of academic preparation based on standardized test scores in nine college…

The purpose of the study was to examine whether the Greek translation of the "Learning Disability Evaluation Scale" (LDES) can be used in the identification of learning disabilities. The LDES was completed by 165 teachers for one of their students, aged 5 to 14 years. The LDES was significantly correlated to students' grades in Math and…

Constrained public funding for universities and the emphasis placed on university-industry interactions mean that universities are increasingly required to compete for industrial funds for research. This in turn means that universities need to develop a customer service culture in order to be competitive and attractive to industry. Many studies…

Many exam programs have begun to include innovative item types in their operational assessments. While innovative item types appear to have great promise for expanding measurement, there can also be genuine challenges to their successful implementation. In this paper we present a set of four activities that can be beneficially incorporated into…

Teacher-based assessment (TBA) is increasingly being promoted in educational policies internationally, with English language teachers being called on to plan and/or implement appropriate assessment procedures to monitor and evaluate student progress in their own classrooms. However, there has been a lack of theorization of TBA in the English…

Differential item functioning (DIF) analysis is a statistical technique used for ensuring the equity and fairness of educational assessments. This study formulates a new DIF analysis method using the information similarity index (ISI). ISI compares item information functions when data fits the Rasch model. Through simulations and an international…
