Clinical Question: When assessing a kindergarten student in the area of early reading skills, does dynamic assessment provide additional classification accuracy over and above static, standardized assessments when determining if the student exhibits a difference in early learning experiences or a true disorder? Method: Systematic Review. Study…

Students with positive attitudes toward statistics are likely to show strong academic performance in statistics courses. Multiple surveys measuring students' attitudes toward statistics exist; however, a comparison of the validity and reliability of interpretations based on their scores is needed. A systematic review of relevant electronic…

Newton's article (2010) makes three main contributions to the literature. First, it is transatlantic, bringing together literatures that have been dealing with similar problems, using sometimes different methods and certainly with distinctive educational, cultural perspectives. He points out that neither of these literatures has all of the…

With increased emphasis on accountability, the use of low-stakes test data to make high-stakes decisions about program effectiveness is on the rise. In order to make valid inferences about what students know and can do, it is crucial to understand the consequences of low and high stakes in testing contexts. As a result, with a sample comprised of…

The idea that validity should be considered a property of inferences, rather than of assessments, has developed slowly over the past century. In early writings about the validity of educational assessments, validity was defined as a property of an assessment. The most common definition was that an assessment was valid to the extent that it…

Validity is an integrated evaluative judgment of the degree to which empirical evidence and theoretical rationales support the adequacy and appropriateness of interpretations and actions based on test scores or other modes of assessment. The principles of validity apply not just to interpretive and action inferences derived from test scores as…

Double cross-validation of a test battery against multiple criterion variables found the first general factor accounts for most criterion variance in cross-validated regression weights. Small contributions are made by mechanical/technical and psychomotor factors. It appears a common general factor plays the major role in validity for a range of…

Assessed validity of the Personality Inventory for Children (PIC) using the Wechsler Intelligence Scale for Children-Revised (WISC-R) and the Wide Range Achievement Test (WRAT) as criterion instruments. The cognitive triad of the PIC was minimally correlated with all intelligence quotient measures and significantly correlated only for reading and…

Data on the predictive and concurrent validity of the SVIB-M Engineer Scale were studied to demonstrate the divergent ways in which validity could be reported and interpreted. (Author)

The article "Thinking About Linking" by Newton (2010) presents a novel philosophical perspective on the way that educational assessments should be linked. Newton starts by describing the linking framework as it was characterized in various publications and identifies a cross-cultural dimension in the definitions and uses of test…

Strong-Campbell Interest Inventory (SCII) results were studied for participants whose most relevant SCII occupational scale was a twin scale. Overall, the other-sex SCII twin scale was about as accurate a predictor as the same-sex scale. (Author)

A new test construction methodology was proposed and its validity and viability were demonstrated. (Author/RK)

Expectancy tables are discussed as a device for interpreting the meaning of test results for those untrained in statistics. Three ways of organizing an expectancy table are discussed: (1) to determine the probability that a student with a given test score will succeed in a specified course; (2) to find out how to pick the best applicants; and (3)…

This study investigated whether the constant decline in Scholastic Aptitude Test (SAT) mathematics scores since 1963 reflected a decrease in student mathematical ability or the SAT's inadequacy in measuring mathematical ability. Findings indicated a very low correlation between SAT math scores and overall college math grades of six graduating…

The use of the regression equation derived from the Anglo-American sample to predict grades of Mexican-American students resulted in overprediction. An examination of the standardized regression weights revealed a significant difference in the weight given to the Scholastic Aptitude Test Mathematics Score. (Author/BB)
