The feasibility of inferring relative task difficulty values and relative task aptitude requirements for a variety of tasks in the General and Administrative work areas is discussed. It was established that there was a high positive relationship between relative task difficulty values, as designated by work supervisors, and the corresponding…

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…

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…

A series of three experiments was conducted for the purposes of (1) clarifying problems of previous research on the relationship between working memory capacity and performance on figural analogy tasks, and (2) exploring developmental issues concerning executive strategies, working memory capacity, and perceptual processing. Directly manipulating…

A task force of opticians and educators in British Columbia was assembled to determine the knowledge and skills required of dispensing opticians and contact lens specialists. The ideas generated by the task force were analyzed and distilled into the standardized tasks listed in this document, using Krathwohl's taxonomy. The document contains 36…

Two studies of three youths (ages 12-14) with severe mental retardation, who used aggression and self-injury to avoid difficult instructional situations, found that simple commands interspersed among more challenging instructional trials were effective at increasing the learners' responsiveness to instructions and decreasing levels of problem…

Cognitive theories disagree about the processes and the number of abilities involved in transitive reasoning. This led to controversies about the influence of task characteristics on individuals' performance and the development of transitive reasoning. In this study, a computer test was constructed containing 16 transitive reasoning tasks having…

The nature of the message used by children, 4 1/2 and 6 1/2 year-old, was studied in a spatial description task. Speaker and listener were separated from one another by an opaque screen, and had to exchange information. Speaker were asked to describe a board showing eight objects placed in a room, and listeners were instructed to draw a similar…

Web site usability concerns anyone with a Web site to maintain. Libraries, however, are often the biggest offenders in terms of usability. In our efforts to provide users with everything they need for research, we often overwhelm them with sites that are confusing in structure, difficult to navigate, and weighed down with jargon. Dowling College…

This paper explored task difficulty from the perspective of the learner. It investigated the relationship between student perception of task difficulty and actual difficulty as measured by successful completion of a task. The study also collected information on those factors identified by students themselves as implicated in task difficulty.…

This annotated bibliography developed in connection with an ongoing investigation of the use of computer simulations for fault diagnosis training cites 61 published works taken predominantly from the disciplines of engineering, psychology, and education. A review of the existing literature included computer searches of the past ten years of…

This review examined the sequencing and grading of tasks in English-as-a-Second-Language (ESL) task-based learning pedagogy. Recent research on task-based learning has focused on cognition and the role that cognitive processes play in determining the ease or difficulty of any particular task. It is argued that an understanding of the effects on…

The development of a probabilistic model for validating Gange's learning hierarchies is described. Learning hierarchies are defined as paired networks of intellectual tasks arranged so that a substantial amount of positive transfer occurs from tasks in a lower position to connected ones in a higher position. This probabilistic validation technique…

The purpose of the current investigation was to determine if the experimental analysis of antecedent variables conducted in English and in Spanish would identify effective and ineffective instructions for response accuracy for Spanish-speaking English language learners. An antecedent variable (i.e., directive complexity) arranged in a hierarchical…
