Relational complexity (RC) theory conceptualizes an individual's processing capacity and a task's complexity along a common ordinal metric. The authors describe the development of the Latin Square Task (LST) that assesses the influence of RC on reasoning. The LST minimizes the role of knowledge and storage capacity and thus refines the…

The dance studio typically features a wall of mirrors; however, there has been little research on the pedagogical advantages and disadvantages of mirrors in the training environment. Psychological studies on objective self-awareness, the ability to see one's self as an object, suggest that the mirrors magnify this state. How this increased…

Objectives: To illustrate how cognitive interviewing techniques can be used to identify question-response problems for poorer and less educated survey respondents and to describe how qualitative analyses of interviews can improve survey questionnaires. Methods: A cognitive interviewing project testing a general health questionnaire was…

This study provides data from an existing review of secondary data and a survey of dual enrollment managers on the topic of Mississippi community and junior colleges' dual enrollment collaborations with secondary schools and parents of home-schooled students. Dual enrollment, also known as dual credit, concurrent enrollment, and credit based…

This paper presents a goal-based scenario approach to teaching introductory database concepts to undergraduates using two different scaffolding methods. One method, termed "worked-out examples," attempts to reduce extraneous cognitive load by requiring students to complete increasingly complex missing parts of worked out examples. The other…

Reading is a complex skill, vital for the postgraduate student. However, many international postgraduate students experience considerable difficulty when applying their reading practices learnt in their own countries. This paper, part of a larger study, aims to provide insights into the reading practices of Indian/Bangladeshi postgraduate students…

English as a Foreign Language (EFL) freshman students at the College of Languages and Translation received direct instruction in adjective-forming suffixes, then they took an immediate and a delayed test. Error analysis showed that 36% of the responses were left blank or the subjects duplicated the stimulus word. In 32% they mismatched the word…

In this cross-national study, the authors compared mathematics self-efficacy beliefs of American (n = 107) and Taiwanese (n = 188) middle-school students for level and calibration (accuracy and bias). Taiwanese students surpassed Americans in math achievement. American students evidenced slightly higher self-efficacy levels for easy math items but…

This study examined initial evidence of changes in fit to a unidimensional model for some language tests at multiple ability levels. Seven data sets were analyzed using the first phase of exploratory factor analysis: principal component eigenvalue extraction. Each data set is analyzed at varying n-sizes: whole group; random subsample; and five…

Several exploratory analyses of the fifths data generated by Test of English as a Foreign Language (TOEFL) item analyses were developed in order to evaluate the effects of options on the discriminability of difficult items and to identify difficult items with low, unreliable biserials that had been rejected by test developers, but for which…

This study was designed to compare the accuracy of three commonly used ability estimation procedures under the graded response model. The three methods, maximum likelihood (ML), expected a posteriori (EAP), and maximum a posteriori (MAP), were compared using a recovery study design for two sample sizes, two underlying ability distributions, and…

Modern applications of computerized adaptive testing (CAT) are typically grounded in item response theory (IRT; Lord, 1980). While the IRT foundations of adaptive testing provide a number of approaches to adaptive test scoring that may seem natural and efficient to psychometricians, these approaches may be more demanding for test takers, test…

Because of the lack of error-free, on-task performance by young children, cognitive modeling has not generally been considered an appropriate technique for characterizing computer use by young children. It is argued that cognitive modeling can be a useful strategy for organizing data on children's performance when the domain being studied is…

This study is the first stage of a wider enquiry into alternative ways of assessing the readability of specialist texts. The interest in assessing these texts arose from the need to grade 60 medical journal articles for an individualized English-as-a-Foreign-Language reading scheme for doctors. The study reports on an investigation of subjective…

Multiple group factor analysis is described and illustrated through a simulation involving 5,000 examinees. The estimation process of the group factors were implemented using the TESTFACT program of Wilson and others (1987). Group factor analysis is described as a special case of confirmatory factor analysis. Group factors can be computed based on…
