The evaluation of learning in mathematics is a worldwide problem, therefore, new methods are required to assess the understanding of mathematical concepts. In this paper, we propose to use the Item Response Theory to analyze the understanding level of undergraduate students about the real function mathematical concept. The Bayesian approach was…

"Cyberbullying"--the intentional, repeated online harassment of a person with less perceived social power--is a pervasive issue facing today's college students. As a result of cyberbullying, victimized students can suffer social, psychological, and academic consequences. This article reports the psychometric validation of a cyberbullying…

Test developers are continually exploring the possibilities Computer Based Assessment (CBA) offers the Mathematics domain. This paper describes the trial of the Place Value Assessment Tool (PVAT) and its online equivalent, the PVAT-O. Both tests were administered using a counterbalanced research design to 253 Year 3-6 students across nine classes…

The Canadian Little Developmental Coordination Disorder Questionnaire (Little DCDQ-CA) is a parent-report screening instrument that identifies 3- to 4-year-old children who may be at risk for Developmental Coordination Disorder (DCD). We tested the criterion validity of the Little DCDQ-CA in a sample of preschool-aged children in the United States…

Student Experience surveys are used to measure student attitudes towards their campus as well as to initiate conversations for institutional change. Validity evidence to support the interpretations of these surveys' results, however, is lacking. The first purpose of this study was to compare three Differential Item Functioning (DIF) methods on…

General education programs often offer students a choice among various courses to fulfill a specific requirement. However, the extent to which these courses equally enable students to achieve the intended learning outcomes can vary, potentially giving some students an unintended advantage. This article evaluates whether students are inadvertently…

Even with extensive retention research dating from the 1960s, community colleges still struggle to identify the reasons why students do not return to college. Data mining has allowed these retention models to evolve to identify new patterns among student populations and variables. The purpose of this study was to create a predictive model for…
