Objective: Elucidation of clinically relevant subtypes has been proposed as a means of advancing treatment research, but classifying anorexia nervosa (AN) patients into restricting and binge-eating/purging types has demonstrated limited predictive validity. This study aimed to evaluate whether an approach to classifying eating disorder patients on…

Though calibration of an achievement test within psychological and educational context is very often carried out by the Rasch model, data sampling is hardly designed according to statistical foundations. However, Kubinger, Rasch, and Yanagida (2009) recently suggested an approach for the determination of sample size according to a given Type I and…

In education theory, Bloom's taxonomy is a well-known paradigm to describe domains of learning and levels of competency. In this article I propose a calculus capstone project that is meant to utilize the sixth and arguably the highest level in the cognitive domain, according to Bloom et al.: evaluation. Although one may assume that mathematics is…

Current school curriculum documents require that justification and proof become a significant part of the mathematics classroom culture. In order to determine how well secondary level student teachers can complete a valid mathematical proof the researcher administered, the same mathematical task of Balacheff (1988) to a group of student teachers…

This study investigated preschoolers' living kinds conceptualization by employing an extensive stimulus set and alternate indices of understanding. Thirty-four 3- to 5-year-olds and 36 adult undergraduates completed 3 testing phases involving 4 object classes: plants, animals, mobile, and immobile artifacts. The phases involved inquiries…

Computer-adaptive classification tests focus on classifying respondents in different proficiency groups (e.g., for pass/fail decisions). To date, adaptive classification testing has been dominated by research on dichotomous response formats and classifications in two groups. This article extends this line of research to polytomous classification…

In the wake of the September 2001 attacks, the U.S. government founded the Department of Homeland Security (DHS) with responsibility to develop a National Infrastructure Protection Plan for securing critical infrastructures and key resources. DHS established interdisciplinary networks of academic expertise administered through Centers of…

Background: The purpose of this study is to describe feasibility and test-retest reliability of the six-minute walking distance test (6MWD) and an adapted shuttle run test (aSRT) in persons with severe intellectual and sensory (multiple) disabilities. Materials and Methods: Forty-seven persons with severe multiple disabilities, with Gross Motor…

During the last decade, expanding research investigating the school subject Physical Education (PE) indicates a promotion of inequalities regarding which children benefit from PE teaching. Outdoor education and its Scandinavian equivalent "friluftsliv," is a part of the PE curriculum in many countries, and these practices have been…

This paper uses Sizer and Sizer's concept of "shoving" to examine the school experiences of a group of young people who left mainstream school early and some time later enrolled in an alternative educational setting designed to reengage early school leavers in formal learning. "Shoving" is a way to explain why so many young…

A child's acquisition of adaptive behavior and skills may constitute his or her most important goal during infancy and early childhood. In addition, adaptive behavior data often are required when making decisions under Part C of the 2004 Individuals With Disabilities Education Improvement Act. This study reports the results of a factor analysis of…

This paper explores the complex and shifting dimensions of the social, cultural and bodily differences that impact on learners and their learning. Our theoretical argument proceeds in five stages. First, we build a typology of terms used to classify demographic differences for the purposes of designing, implementing and evaluating the…

The 21st century learner resides in an advanced global society that is led by the waves of the economy, advances in the technological world, concern around our safety and security, as well as demographical changes (Carver & Markatos-Soriano, 2007). The trends suggest education needs to equip students with the attitudes that promote respect for…

Framed in theories of social semiotics, this multiple case study describes and categorizes the actional-operational modes used by three middle school earth science teachers throughout the course of one school year. Data included fieldnotes, photographs, and video recordings of classroom instructions as well as periodic interviews with the…

Problem Statement: Difficulties in the learning process usually emerge from the problem of mental representations constructed by students in their interactions with the world. This previous knowledge and these ideas are in contradiction with scientific facts, and are known as misconceptions or alternative ideas. Thus, an analysis of the mental…
