We investigated processing of numerical order information and its relation to mechanisms of numerical quantity processing. In two experiments, performance on a quantity-comparison task (e.g. 2 5; which is larger?) was compared with performance on a relative-order judgment task (e.g. 2 5; ascending or descending order?). The comparison task…

The effects of 2 weeks of no, general, and task-related enhanced movement experiences on 8- to 12-week-old infants' (N=30) hand and foot interactions with objects were assessed using standard video and motion analysis. For hand object interaction ability, general and task experience led to greater success than did no experience, and task…

In the voluntary task switching procedure, subjects choose the task to perform on a series of bivalent stimuli, requiring top-down control of task switching. Experiments 1-3 contrasted voluntary task switching and explicit task cuing. Choice behavior showed small, inconsistent effects of external stimulus characteristics, supporting the assumption…

As more and more schools adopt school-wide positive behavior support (SWPBS) as a model for school improvement and the success of initial demonstration sites becomes evident, districts are faced with expansion and sustainability issues. Careful planning of these implementation efforts requires district personnel to be familiar with the resources…

We propose a framework for evaluating the degree of authenticity of instructional tasks used within a teacher education program. First, we provide a defense for authenticity as an exemplary aspect of education. Second, we synthesize the theoretical literature on authenticity into conceptual codes. Using these codes, we build our authenticity…

Tasks provide a framework for communicative performance. Underlying each task is a set of learning opportunities--potential activities for learning. Not all of these opportunities are exploited for learning by teachers or learners. It is proposed that, when using tasks, the range of such learning opportunities needs to be identified and modelled…

The Spellings Commission report stresses that higher education must become more accountable, more transparent, and more open to the scrutiny of its stakeholders. The key word is always "accountability," to which the canonical reaction among educators is a reaffirmation of the remarkable diversity of American colleges and universities and the…

Teachers' competence to estimate the effectiveness of learning materials is important and often neglected in programmes for teacher education. In this lecture I will try to explore the possibilities of designing scaffolding instruments for a "priori" assessment of language learning tasks, based on insights from SLA and cognitive psychology, more…

What is involved in consolidating a new mathematical abstraction? This paper examines the work of one student who was working on a task designed to consolidate two recently constructed absolute function abstractions. The study adopts an activity theoretic model of abstraction in context. Selected protocol data are presented. The initial state of…

This approach to task analysis includes descriptions of (1) inputs, outputs, and jobs; (2) flow of materials and decisions between jobs; (3) inputs, major tasks, and outputs of each job; (4) sequence of steps for major tasks; (5) heuristics/algorithms for each sequence step; and (6) information needed to use heuristics algorithms. (EAO)

Defines and discusses task analysis and presents a method by which goals can be achieved with the integration of task analysis and design. Highlights include the fact that prerequisites must be kept in mind during the development process. (JKP)

Describes a project control system for Indiana State University's Library Systems and Automation Department. Organizing project information, managing priorities, defining projects and recurring activities, time management, identifying tasks, and service requests are discussed. The management decision-making process for new, proposed, and completed…

Examines problems of existing courseware authoring systems and suggests the use of knowledge-based techniques. A prototype knowledge-based representation language called GTE (Generic Tutoring Environment) is described that could form the basis of a full authoring environment, including generic tasks and instructional methods, domain knowledge, and…

Analysis of binary choice behavior in iterated tasks with immediate feedback reveals robust deviations from maximization that can be described as indications of 3 effects: (a) a payoff variability effect, in which high payoff variability seems to move choice behavior toward random choice; (b) underweighting of rare events, in which alternatives…

This article is a synopsis of three performance tasks designed for students enrolled in an educational leadership graduate level course Using Data to Affect Change. These performance tasks address the requisite knowledge and skills that an effective school leader should possess in order to improve the quality of instruction and at the same time…
