A series of six experiments was conducted to increase understanding of human performance on diagnostic tasks, and in the process to investigate the feasibility of using context-free computer-based simulations to train troubleshooting skills. Three simulated diagnostic tasks were developed: a simple context-free task, a complex context-free task,…

This document contains one of two assessment tools developed by Project Proud Option, which developed and field-tested a set of student- and job-assessment instruments that provide a strategy for determining (1) the vocational skills required on a particular job; (2) the functional skill levels of a particular student; (3) a process to determine…

In this study, a systems methodology was devised for determing knowledge and skills common to piloting tasks required by differing aircraft missions to form a data base for developing a task oriented flight training program. The general approach was to identify and classify specific tasks performed by Air Force pilots, with the required level of…

The definition of hierarchical structure is reviewed, together with psychometric and experimental evidence regarding the existence of specific structures. A mathematical model including hierarchical and nonhierarchical options for a two component task is presented, along with an experimental design appropriate for testing the model and related…

The purpose of this study was to investigate whether students expected course difficulty to be reflected in grade distributions and in the amount of out-of-class effort required for success. Students from both upper and lower division classes described the amount of time they expected to spend preparing for an easy class, a difficult class, and a…

On-line comprehension studies of flexible word-order languages find that noncanonical ("scrambled") structures induce more difficulty than canonical structures [e.g., Hyona & Hujanen, "Q. J. Exp. Psychol." 50A (1997) 841-858], with this difference being attributed to the structural complexity/infrequency of these forms. However, by presenting…

This article proposes two general instructional strategies that a course designer or materials writer may use to create a second language course that makes new demands on learners, yet contains feasible learning tasks. First, course designers can manipulate task components believed to determine task difficulty, components such as input text, the…

BASED LARGELY ON AIR RESEARCH ON SHELTER MANAGEMENT SIMULATION, AN ANALYSIS WAS MADE OF THE IMPACT OF THE LARGE, COMPLEX SHELTER ON SHELTER MANAGEMENT TRAINING NEEDS. THE LARGE SHELTER REQUIRES THE TYPE OF LEADERSHIP THAT ONLY THOSE WHO ALREADY HAVE SUPERVISORY SKILLS CAN SUPPLY. SUCH PEOPLE ARE NEITHER ATTRACTED NOR HELPED BY THE USUAL SHELTER…

The relationships between the characteristics of human tasks and the abilities required for task performance are investigated. The goal of the program is to generate principles which can be used to identify ability requirements from knowledge of the characteristics of a task and of variations in the conditions of task performance. Such knowledge…

Discussion centered on three sets of factors that may influence the variability observed in "concept identification" (concept formation and discrimination learning) studies: stimulus characteristics, incentives employed, and subject characteristics. Stimulus characteristics are described in terms of the number of dimensions…

Questions investigated in this study deal with relationships between map problem difficulty and students' acquired level of intellectual development, the effects of sequential mastery of map concepts, and the optimum age to introduce certain map concepts in the geography curriculum. In the main investigation, which covered varied selected,…

Presents a study of task liking and intrinsic motivation using self-esteem, task label, and feedback analysis of variance. Reports that, for subjects with high self-esteem, feedback had strong impact on liking of a difficult task. Concludes that, for subjects with low self-esteem, feedback had strong impact on liking easy tasks. (DK)

Children (ages 5, 7, and 9 years) and young adults completed two visual attention tasks that required them to make a forced choice identification response to a target shape presented in the center of a computer screen. In the first task (high correlation condition) each target was flanked with the same distracters on 80% of the trials (valid…

Statistical methods employed to test individual differences in dual-task performance and the existence of a general time-sharing ability are reviewed and critiqued. Specifically, both the types of data being collected and the types of data analysis procedures have been inadequate to the critical evaluation of a hypothetical…

This paper analyses new methods of teaching skiing in terms of a computational paradigm for learning called increasingly complex microworlds (ICM). Examining the factors that underlie the dramatic enhancement of the learning of skiing led to the focus on the processes of simplification, debugging, and coaching. These three processes are studied in…
