This paper reviews studies that have used instructional variables as nonaversive interventions for problem behaviors of individuals with severe disabilities. These include student choice of task, task variation, pace of instruction, interspersal of high probability tasks, partial versus whole task training, decreasing task difficulty, and a…

Effects of dimensionality on ability estimation of an adaptive test were examined using generated data in Bayesian computerized adaptive testing (CAT) simulations. Generally, increasing interdimensional difficulty association produced a slight decrease in test length and an increase in accuracy of ability estimation as assessed by root mean square…

Discusses how students generate meanings for mathematical word problems, develops a generative predicational model to account for students' comprehension of word problems, and describes an empirical study of Israeli sixth graders that was designed to test the model. Talk aloud protocols of the students are analyzed, and hypotheses tested are…

Challenges in applying cognitive strategy research to complex knowledge domains in students with learning disabilities include the need to focus on deficits in domain-specific knowledge; adaptation of assessment designs to answer cognitive questions; and procedures for individual cognitive strategy instruction in group settings. A research agenda…

A University of Hawaii study compared objective and subjective assessments of the three-step triple jump examination which tests medical students' clinical problem-solving processes. Subjects were 58 first-year students. Results found the subjective assessments were more consistent across problems of varying difficulty level than were objective…

This article presents an explorative study, which is part of a comprehensive project to examine the impact of epistemological beliefs on metacognitive calibration during learning processes within a complex hypermedia information system. More specifically, this study investigates: 1) if learners differentiate between tasks of different complexity,…

Assessing use of language learning strategies has become commonplace around the world. One strategy assessment tool is the questionnaire, which usually asks students to report on their typical, general use of language learning strategies. Because of this general focus, most questionnaires do not require respondents to complete an actual language…

Conventional wisdom is that some topics in introductory psychology are more difficult for students than others. Such wisdom seems reasonable given mismatches between students' and instructors' expectations and variations in both instructor expertise and student motivation across topical areas. Five instructors pooled students' exam performance…

Background: The objective of this study is to identify intact and deficient cognitive processes in children with attention deficit hyperactivity disorder (ADHD) and children with high functioning autism (HFA). Method: Three rigorously diagnosed groups of children aged between 6 and 12 years (54 ADHD, 41 HFA, and 41 normal controls) were tested on…

Purpose: To examine the critical roles of leadership in higher education and to define how such roles enable an environment that embraces the demands of a knowledge-based organization. Design/methodology/approach: Through interviews with executive leadership in several higher education institutions, the ontology of knowledge management was…

Evidence of phonological awareness levels usually comes from English-speaking children. The evidence in Spanish is scarce. The present study examined the phonological awareness of syllables, onsets--rimes, and phonemes, extending the Treiman and Zukowski (1991) results to preliterate and literate Spanish-speaking children. The sample comprised…

This paper assesses university students' acquisition of simple and complex knowledge, in exploring whether the knowledge gap hypothesis (KGH) with its origins in community-based research into people's informal learning from mass media, provides insights into students' acquisition and retention of information. The KGH posits that attempts to…

Several studies support that stored memories undergo a new period of consolidation after retrieval. It is not known whether this process, termed reconsolidation, requires the same transcriptional mechanisms involved in consolidation. Increasing evidence supports the participation of the transcription factor NF-[Kappa]B in memory. This was…

This paper proposes a methodology to calculate both the difficulty of the basic problems and the difficulty of solving a problem. The method to calculate the difficulty of problem is according to the process of constructing a problem, including Concept Selection, Unknown Designation, and Proposition Construction. Some necessary measures observed…

Simple matching models of decision making are no longer sufficient as a basis for career counselling and education. The challenge for contemporary careers advisers is how to communicate some of the complexities of modern career development to their students; in particular, the apparently contradictory relationship between the need for planning and…
