Understanding the effects of class size reduction (CSR) has been an enduring issue in education. For the past 3 decades, Project STAR has stimulated research and policy discussions regarding the effects of CSR on a variety of outcomes. Schanzenbach (2007) reviewed STAR studies and concluded that small classes improved student academic outcomes.…

The Common Core State Standards Initiative is the latest development in a long history of standards-based-reform in the United States. As of November 4, 2011, 46 states and the District of Columbia have adopted new curricular standards, called the Common Core State Standards (CCSS). These states and the District of Columbia are now implementing…

An Objective Structured Clinical Examination (OSCE) is an effective method for evaluating competencies. However, scores obtained from an OSCE are vulnerable to many potential measurement errors that cases, items, or standardized patients (SPs) can introduce. Monitoring these sources of errors is an important quality control mechanism to ensure…

In the United States there is an increasing tendency to view the only educational research worthy of federal funding as that which is designed as an experiment using randomised controls. One of the foundational assumptions underlying this research design is that the results of such research are meant to be generalisable beyond any particular…

Used the domain sampling model of generalizability theory to study ways of improving a construct measure, the Achievement Motives Scale (AMS) (R. Nygard and T. Gjesme, 1973). AMS results for 504 Chinese high school students and 252 U.S. graduate students are the basis for suggestions to improve the two language versions' approximations to the…

Although multivariate generalizability theory was developed more than 30 years ago, little published research utilizing this framework exists and most of what does exist examines tests built from tables of specifications. In this context, it is assumed that the universe scores from levels of the fixed multivariate facet will be correlated, but the…

This study examined the generalizability and dependability of a performance-based assessment in algebra. Four forms of a five-item test were constructed using different subsets of eight items based on attributes from task analysis. Subjects included 142 "algebra 2" students from 2 high schools in the Midwestern United States and 148 11th…

The ECFMG[R] Clinical Skills Assessment (CSA[R]) was developed to evaluate whether graduates of international medical schools (IMGs) are ready to enter graduate training programs in the United States. The patient note (PN) exercise, conducted after a 15-minute interview with a standardized patient (SP), is specifically used to assess a candidate's…

This study examined the generalizability of the internal/external (I/E) frame of reference model of academic self-concept development. The "external" component of the model refers to comparing one's achievement with one's peers; in LISREL causal modeling, this external comparison is presented as positive paths. The "internal"…

This article addresses an important problem that faces educators in assessing students' competence levels in learned tasks. Data from 165 students from Massachusetts and Minnesota in the United States are used to examine the validity of five assessment modes (multiple choice test, scenario, portfolio, self-assessment and supervisor rating) in…
