This paper concerns an investigation of the manner in which typicality constrains graded membership in antonymous dimensional adjectives such as "short/tall" and "cheap/expensive" using the conceptual spaces framework. In this framework, items are organized in a space comprised of one or more dimensions along which they can be…

A response model that is able to detect guessing behaviors and produce unbiased estimates in low-stake conditions using timing information is proposed. The model is a special case of the grade of membership model in which responses are modeled as partial members of a class that is affected by motivation and a class that responds only according to…

This study distinguished two groups of mothers who have not communicated with their young adolescents about sexual health based on their intentions of having these discussions. We also compared these 2 groups to mothers who have had such communications. Overall, 29% of mothers had engaged in sexual discussions with their adolescent in some detail…

This causal comparative study used a set of predictable variables, including school configurations, to predict student proficiency on the Arizona Instrument to Measure Standards (AIMS) test in reading and math. The school configurations were K-8 and middle school. The researcher analyzed the 2011-2012 AIMS reading and math achievement scores of…

Current methods for detecting growth of students' problem-solving skills in math focus mainly on analyzing changes in test scores. Score-level analysis, however, may fail to reflect subtle changes that might be evident at the item level. This article demonstrates a method for studying item-level changes using data from a multiwave experiment with…

Higher education in America has a long tradition of civic engagement education. Although there is theoretical and rhetorical support, many institutions still struggle with implementing effective civic engagement on their campuses. The aim of this study was to provide an understanding of factors that contribute to successful civic engagement,…

A study analyzed and compared four selected models in the cyclical tradition of group development as a basis for identifying possible issues and implications for future theory building. The theorists whose models were examined were Leland Bradford, Jack Gibb, William Schutz, and Theodore Mills. Both historical and conceptual perspectives of the…

Student interaction patterns in eight elementary school classrooms were examined to investigate (1) the relationship between interaction patterns and sociometric indicators of friends, (2) the process by which children become stratified, and (3) the structure of peer relationships in classrooms. Chapter 1, the introduction, briefly discusses the…

The IADIS CELDA 2012 Conference intention was to address the main issues concerned with evolving learning processes and supporting pedagogies and applications in the digital age. There had been advances in both cognitive psychology and computing that have affected the educational arena. The convergence of these two disciplines is increasing at a…
