The gold-standard for evaluating the effect of an educational intervention on student outcomes is running a randomized controlled trial (RCT). However, RCTs may often be small due to logistical considerations, and resulting treatment effect estimates may lack precision. Recent methods improve experimental precision by incorporating information…

This article describes standardised testing in Denmark and the protections guaranteed to avoid "high stakes". It explains the use of computer-based "adaptive tests" which adjust to an appropriate level for each student. It is an abbreviated version of an article from 2011 in the "Journal for Applied Testing…

Purpose: The current study used a case review diagnostic assessment task to examine the diagnostic decisions speech-language pathologists (SLPs) working in the United States made after reviewing child language cases. Method: Fourteen SLPs were given 5 case studies that presented either congruent or incongruent results between standardized testing…

Selection decisions have a major impact on our education, occupation, and quality of life, and the role of standardized tests in selection has always been a source of controversy. Here, I consider various definitions of fairness in measurement and selection--those emerging from within educational measurement and statistics, those from philosophy,…

This study was designed to determine if a relationship exists between placement assessment scores and student attrition for first year college students at a technical college in the Midwest. The data included de-identified student scores on four standardized assessments used by the school for admissions and course determination, as well as various…

Purpose: This study investigated changes in oral-verbal expressive language associated with improvements following 2 treatment periods of constraint-induced language therapy in 4 participants with stroke-induced chronic aphasia. Generalization of treatment to untrained materials and to discourse production was also analyzed, as was the durability…

This research brief provides an overview of methods for estimating the size of achievement gaps. Unfortunately many researchers, analysts, and policy-makers use subjective methods (e.g., visual inspection) to evaluate group differences. Another common method is to take the difference between groups in percent proficient, but there are a number of…

Purpose: Evidence has shown that group conversation treatment may improve communication and reduce social isolation for people with aphasia. However, little is known about the impact of conversation group treatment on measures of discourse. This project explored the impact of conversation treatment on measures of monologic discourse. Method: In…

The "TOEFL Junior"® Standard test is a tool for measuring the English language skills of students ages 11+ who learn English as an additional language. It is a paper-based multiple-choice test and measures proficiency in three sections: listening, form and meaning, and reading. To date, empirical evidence provides some support for the…

Relevance interventions have shown a great potential to foster motivation and achievement (Lazowski & Hulleman, 2016). Yet, further research is warranted to test how such interventions can be successfully implemented in practice. We conducted a cluster-randomized trial in ninth-grade math classrooms to test the effectiveness of a relevance…

The purpose of this study was to investigate whether language skills can predict teacher reports of social skills (empathy and assertion) and social behavior (prosocialness, aggression, and victimization) in preschool children. Relationships among social skills and behaviors were also examined. Ninety-eight preschool children were administered…

This paper focuses on difficulties that primary school students have in facing mathematical word problems. In particular, we are interested in exploring how they develop in the transition from grade 2 to grade 5. The research basis of the hypothesis is that some difficulties detected in grade 5 are already predictable in grade 2. Starting from the…

Resilient readers comprehend written language despite word reading deficits. The reading resiliency framework specifies candidate protective factors hypothesized to mitigate adverse effects on reading comprehension arising from phonological decoding deficiencies and, consequently, illuminates how some individuals exhibit relative reading…

In the frame of national Italian standardized assessments in mathematics, a didactic phenomenon has been observed concerning students' behaviour when answering an item: students are inclined towards not accepting an output which is not clearly recognizable with something distinct from the starting inputs. The observed effect seems to originate…

The focus of this study is to evaluate the effectiveness of the Student Success Skills group counseling (SSSGC) intervention with grade 9 students identified as at risk to dropout. This study analyzed two years of non-identifiable student data (N = 167) collected by school counselors at one high school in south Florida. An analysis of covariance…
