It is demonstrated that the popular three-parameter logistic model can lead to markedly inaccurate individual ability level estimates for mixture populations. A theoretically and empirically important setting is initially considered where (a) in one of two subpopulations (latent classes) the two-parameter logistic model holds for each item in a…

Positive psychology has been an influential movement within psychology in the early years of the twenty-first century. It is now timely to assess the value of its contribution to career education and guidance. This paper provides a critique of this perspective. Positive psychology can enrich approaches to career development. It can provide a…

Individualism is the dominant value system in Western cultures and, as such, it affects the conduct of every aspect of human endeavour, including education. One of the most enduring effects on education has been the search for individual differences that can explain and predict variation in student achievement, with the hope that pedagogical…

A multidimensional item response theory model that accounts for response style factors is presented. The model, a multidimensional extension of Bock's nominal response model, is shown to allow for the study and control of response style effects in ordered rating scale data so as to reduce bias in measurement of the intended trait. In the current…

The Interactive Learning Model illustrates how we process information (cognition), perform learning tasks (conation), and develop a self when performing difficult learning tasks (affectation). Individuals approach learning tasks with varying degrees of sequence, precision, technical reasoning, and confluence. These ingredients are embedded in the…

Inhelder and Piaget (1958) studied schoolchildren's understanding of a simple pendulum as a means of investigating the development of the control of variables scheme and the "ceteris paribus" principle central to scientific experimentation.The time-consuming nature of the individual interview technique used by Inhelder has led to the development…

Objective public testing methods were brought into use in language programs in the 1930s, primarily to justify decisions to exclude unqualified students from high school foreign language classes. In the United States, after World War II, government language programs supported research into the assessment of language aptitude to improve selection…

Limitations seen in traditional educational procedures are discussed, and three new directions are suggested as being important emphases for testing. A new perception of measurement in which children have positions along particular concept dimensions or "lines" is discussed in terms of traditional testing notions including variables, item banks…
