Reform movements in mathematics education advocate that mathematical argumentation play a central role in all classrooms. However, research shows that mathematics teachers at all grade level find it challenging to support argumentation in mathematics classrooms. This study examines the role of teachers' mathematical knowledge in teachers' support…

A number of studies report that frequency is a poor predictor of acceptability, in particular at the lower end of the frequency spectrum. Because acceptability judgments provide a substantial part of the empirical foundation of dominant linguistic traditions, understanding how acceptability relates to frequency, one of the most robust predictors…

This study aims to study the control of interference and self-control in students with different levels of probabilistic thinking style (PTS). The study covered 90 students (average age 20 ± 3.03 years). The sample subjects were formed through the approximate modeling method. The experimental group covered students from the 1st to the 4th year. At…

The aim of this study is to explore Israeli high school graduates' mathematical explanations for the spread of the coronavirus, given that the mathematics required to do so was part of their school curriculum. An online questionnaire consisting of two sections provided a variety of potential framings for explaining the phenomenon. The first…

Background: Friendship is important to quality of life, yet people with intellectual disability have more restricted social networks and fewer friends outside family and support staff. Method: Data from a nationally representative longitudinal study of older adults with intellectual disability (aged >40) examined rates and types of friends.…

Although there exists a large body of literature concerning the impacts of school choice policies, few studies focus on the choices of rural students. Using a unique dataset that includes administrative records, geocoded addresses, and commute times for Michigan public school students over 6 years, I describe who participates in interdistrict…

Knowledge tracing algorithms are embedded in Intelligent Tutoring Systems (ITS) to keep track of students' learning process. While knowledge tracing models have been extensively studied in offline settings, very little work has explored their use in online settings. This is primarily because conducting experiments to evaluate and select knowledge…

The variability in placement of students with autism and intellectual disability and lack of access to general education for these students suggests the need to identify factors associated with placement and then address the role of current policy. This article presents the results of a 5-year trend analysis of placement of students with autism…

The expansion and universalization of educational opportunities in many parts of the world raised expectations that education inequality could be alleviated. Contrary to expectations, however, empirical evidence on educational inequality has been revealed. This is because qualitative differentiation of education programs at a certain level of…

This study examined the effect of the Arizona Instrument to Measure Standards (AIMS) Scholarship on college cohort retention, college cohort completion, and college cohort time to completion--important student performance markers in an era of fiscal accountability. Over the six-year span (2006 - 2012) of this one year, renewable) full-tuition…

This article considers how a handicapping system should be devised for squash. It looks at the American scoring system, and whether it is possible to have a fair system of handicapping. We consider "fair" from a perspective of expected number of rallies won and probability of winning.

This study explores how student employment affects college persistence and how these effects differ by individual likelihood of participating in student employment. I analyze data from the National Longitudinal Survey of Youth 1997 using propensity score matching and stratification-multilevel analysis. This study finds that engaging in intense…

This paper explores the use of irony in narratives that focus on the problem of knowing what we do not know. Sometimes issues arise on a grand scale, as in the literature of Socrates, Pascal, and Descartes, where the question really is whether we can know anything at all or whether all that we can know is that there is nothing worth knowing that…

A key part of determining cut-scores when performing Angoff standard setting is utilizing equating methods to place standard-setting ratings onto the scale used to report scores to examinees. This article describes three equating methods that can be employed to place Angoff ratings onto the scale used to report scores to examinees when applying…

This research study provides an examination of the relatively new fields of Data Analytics and Data Science. We compare word rates in Data Analytics and Data Science documents to determine which concepts are mentioned most often. The most frequent concept in both fields is "data." The word rate for "data" is more than twice the…
