Many academic tests (e.g. short-answer and multiple-choice) sample required knowledge with questions scoring 0 or 1 (dichotomous scoring). Few textbooks give useful guidance on the length of test needed to do this reliably. Posey's binomial error model of 1932 provides the best starting point, but allows neither for heterogeneity of question…

Sixty-five right- and left-handed preschool and school children were tested on three reach-to-grasp tasks of different levels of complexity, performed in three space locations. Our goal was to evaluate how the effect of attentional information related to object location interacts with task complexity and degree of handedness on children's hand…

Based on a previously validated cognitive processing model of reading comprehension, this study experimentally examines potential generative components of text-based multiple-choice reading comprehension test questions. Previous research (Embretson & Wetzel, 1987; Gorin & Embretson, 2005; Sheehan & Ginther, 2001) shows text encoding and decision…

Prior exposure to drugs of abuse has been shown to occlude the structural plasticity associated with living in a complex environment. Amphetamine treatment may also occlude some cognitive advantages normally associated with living in a complex environment. To test this hypothesis we examined the influence of prior exposure to amphetamine on fear…

There is a pervasive perspective that both students and college courses are not what they used to be. A utility maximization model exhibits why students prefer easier courses to those that provide more challenge, and presumably more knowledge. The model also demonstrates why faculty members accommodate these students with less stringent courses.…

Purpose: The purposes of this investigation were to examine the construct dimensionality and range of ability effectively measured by 28 assessment items obtained from 3 different patient-reported scales of communicative functioning, and to provide a demonstration of how the Rasch approach to measurement may contribute to the definition of latent…

To understand the difficulties that many students have with comprehension of mathematics, we must determine the cognitive functioning underlying the diversity of mathematical processes. What are the cognitive systems that are required to give access to mathematical objects? Are these systems common to all processes of knowledge or, on the…

People usually talk about "hot and cold" colours without really thinking of the impact these definitions may have on scientific understanding. These colours are associated with the human sensations of hot and cold, and this idea is consistent with commonsense and daily experience. Interacting with students, we detect conceptual conflicts when they…

In this study, we describe the development of rapid reading measures, sentences presented to students in a nearly subliminal manner, with a literal comprehension question asked following their removal. After administering alternate forms of these measures to students, we present the results from three statistical analyses to ascertain their…

The Department of Accounting at California State University Northridge (CSUN) has developed a unique sequence of courses designed to ensure that accounting students are trained not only in technical accounting, but also acquire critical thinking, research and communication skills. The courses have proven effective and have embedded assessment…

The purposes of this study were to: (1) examine whether or not the construction of concept maps by students improves their achievement and ability to solve higher order questions in chemistry, (2) investigate the differential effect of the treatment by gender and achievement level, and (3) explore the relationships between performance on concept…

Our experience suggests that pre-service primary school teachers have problems with learning science, especially chemistry, and that this negative attitude towards science influences their future teaching. On that premise, the purpose of the study was to determine the level of the pre-service primary school teachers' intrinsic motivation for…

The goal of this article is to frame some new directions to social comparison research in organizational settings. Four themes are developed. First, we examine the role of organizational variables in shaping the basic sub processes in social comparison, such as the selection of referents. The second theme focuses on the meaning of level of…

In a study on L2 proficiency in writing, conducted among 84 Dutch university students of Italian and 75 students of French, manipulation of task complexity led in the complex task to a significant decrease of errors, while at the same time a trend for a lexically more varied text was observed (Kuiken and Vedder 2005, 2007, in press). Based on this…

The structure of the national numeracy strategy (1999) has ensured that whole-class teaching has become a significant feature of the primary mathematics lesson. It is the section of the lesson where children are introduced to new mathematics and therefore there is a need to make it effective. In this article, the author describes her small-scale…
