How do children as young as 2 years of age know that numerals, like "one," have exact interpretations, while quantifiers and words like "a" do not? Previous studies have argued that only numerals have exact lexical meanings. Children could not use scalar implicature to strengthen numeral meanings, it is argued, since they fail to do so for…

Adaptive support for computer-mediated collaboration aims at supporting learners' collaboration in a way that is tailored to their actual needs and by fostering their self-regulation, leading to the acquisition of new collaboration skills. This review gives an example of developing support for a specific collaboration skill: the co-construction of…

This study examines the relationship between teacher knowledge and student learning for 9,556 students of 181 middle school physical science teachers. Assessment instruments based on the National Science Education Standards with 20 items in common were administered several times during the school year to both students and their teachers. For items…

In 2002, an article entitled "Four assumptions of multiple regression that researchers should always test" by Osborne and Waters was published in "PARE." This article has gone on to be viewed more than 275,000 times (as of August 2013), and it is one of the first results displayed in a Google search for "regression…

The process of education, and in particular that involving very young children, often involves students' taking their teachers' word on a good many things. At the same time, good education at every level ought to inculcate, develop, and support students' ability to think for themselves. While these two features of education need not be regarded as…

This study integrated Bayesian hierarchical modeling and receiver operating characteristic analysis (BROCA) to evaluate how interest strength (IS) and interest differentiation (ID) predicted low–socioeconomic status (SES) youth's interest-major congruence (IMC). Using large-scale Kuder Career Search online-assessment data, this study fit three…

As the number of children diagnosed with an autism spectrum disorder (ASD) continues to rise, more children with ASD are accessing early childhood services. Early childhood educators need strategies that benefit a variety of learners served in these settings including those diagnosed with ASD. Shared reading is one routine that is typically used…

This study introduces a co-twin control method commonly used in the medical literature but not often within educational research. This method allows for a comparison of twins discordant for an "exposure," approximating alternative outcomes in the counterfactual model. Example analyses use data drawn from the Florida Twin Project on…

The purpose of this quantitative study was to examine the factors that affect women administrators in higher education at four-year public and private universities in Texas. By comparing private and public universities, the research provided an assessment of similarities and differences of the factors impacting achievement of women in higher…

The purpose of this study is to understand how teachers make sense of data from a complex set of reading assessments and how inferences they derive from the data affect decisions about instruction. There are two key research questions--1) How does a teacher's developing expertise with a complex set of assessments (assessment literacy) affect the…

The shortcomings of the proportion above cut (PAC) statistic used so prominently in the educational landscape renders it a very problematic measure for making correct inferences with student test data. The limitations of PAC-based statistics are more pronounced with cross-test comparisons due to their dependency on cut-score locations. A better…

Today, increasing numbers of teachers at all grade levels are recognizing that inference is a powerful way of thinking and an important 21st century skill for all students to use and develop across the curriculum. Increasing numbers of teachers are also recognizing that developing and implementing integrative curriculum is important at all grade…

Test equating is a statistical procedure for adjusting for test form differences in difficulty in a standardized assessment. Equating results are supposed to hold for a specified target population (Kolen & Brennan, 2004; von Davier, Holland, & Thayer, 2004) and to be (relatively) independent of the subpopulations from the target population (see…

The study of prediction bias is important and the last five decades include research studies that examined whether test scores differentially predict academic or employment performance. Previous studies used ordinary least squares (OLS) to assess whether groups differ in intercepts and slopes. This study shows that OLS yields inaccurate inferences…

There is widespread interest in using various statistical inference tools as a part of the evaluations for individual teachers and schools. Evaluation systems typically involve classifying hundreds or even thousands of teachers or schools according to their estimated performance. Many current evaluations are largely based on individual estimates…
