Measures of workload have been developed on the basis of the various definitions, some are designed to capture the multi-dimensional aspects of a unitary resource pool (Kahneman, 1973) while others are developed on the basis of multiple resource theory (Wickens, 2002). Although many theory based workload measures exist, others have often been constructed to serve the purpose of specific experimental tasks. As a result, it is likely that not every workload measure is reliable and valid for all...
Show moreMeasures of workload have been developed on the basis of the various definitions, some are designed to capture the multi-dimensional aspects of a unitary resource pool (Kahneman, 1973) while others are developed on the basis of multiple resource theory (Wickens, 2002). Although many theory based workload measures exist, others have often been constructed to serve the purpose of specific experimental tasks. As a result, it is likely that not every workload measure is reliable and valid for all tasks, much less each domain. To date, no single measure, systematically tested across experimental tasks, domains, and other measures is considered a universal measure of workload. Most researchers would argue that multiple measures from various categories should be applied to a given task to comprehensively assess workload. The goal for Study 1 to establish task load manipulations for two theoretically different tasks that induce distinct levels of workload assessed by both subjective and performance measures was successful. The results of the subjective responses support standardization and validation of the tasks and demands of that task for investigating workload. After investigating the use of subjective and objective measures of workload to identify a universal and comprehensive measure or set of measures, based on Study 2, it can only be concluded that not one or a set of measures exists. Arguably, it is not to say that one will never be conceived and developed, but at this time, one does not reside in the psychometric catalog. Instead, it appears that a more suitable approach is to customize a set of workload measures based on the task. The novel approach of assessing the sensitivity and comprehensive ability of conjointly utilizing subjective, performance, and physiological workload measures for theoretically different tasks within the same domain contributes to the theory by laying the foundation for improving methodology for researching workload. The applicable contribution of this project is a stepping-stone towards developing complex profiles of workload for use in closed-loop systems, such as human-robot team interaction. Identifying the best combination of workload measures enables human factors practitioners, trainers, and task designers to improve methodology and evaluation of system designs, training requirements, and personnel selection.

Today's focus on high-stakes standardized tests has had a massive impact on education throughout America, and standardized test preparation is one of the ugly, open secrets of education. Ever since 2001 when President Bush signed into law No Child Left Behind (NCLB), a bipartisan reauthorization of Johnson's landmark Elementary and Secondary Education Act of 1965, students have been bombarded with standardized tests from the earliest grades. Politicians believe these measures are the only way...
Show moreToday's focus on high-stakes standardized tests has had a massive impact on education throughout America, and standardized test preparation is one of the ugly, open secrets of education. Ever since 2001 when President Bush signed into law No Child Left Behind (NCLB), a bipartisan reauthorization of Johnson's landmark Elementary and Secondary Education Act of 1965, students have been bombarded with standardized tests from the earliest grades. Politicians believe these measures are the only way to remedy the perceived weaknesses in the education system because (")stringent accountability mandates… [provide] vital levers of change, inclusiveness, and transparency of results(") (Education Week, 2011, para. 15). Yet as time progresses, the quantity and importance of the exams increase to such proportions that, by the time students are in high school, their performance dictates whether they will graduate or attend college. While proponents of such exams say that they only test the skills that students ought to be learning anyway, the reality tends to be that teachers start to focus only on the specific questions the test will cover, and thereby lose the ability to provide full, comprehensive education. "Teaching to the test" is the much-maligned experience of most high schools. In order to combat the pressure students feel to perform and teachers feel to shortchange the learning experience, a (")Build Your Own Adventure(") manual designed around research-based principles demonstrated to improve student learning gains will allow students to focus on the key areas needed to improve test performance, demystify the test itself, and thus help students obtain score improvement. In so doing, students will not only perform better on standardized assessments, but ultimately be able to attend more elite colleges.

Show moreThis study conducted at the University of Central Florida was completed to inform the Ed. D. in Education program within the College of Education and Human Performance. The main purpose of the study was to determine the Dissertation in Practice (DiP) project types that should be allowed for use as the capstone requirement based on a needs analysis of K-12 schools and school districts. The secondary purpose was to inform the instructional design of the program to ensure the necessary skills and knowledge required are included in the program.The study was conducted in the University of Central Florida's Ed. D. in Education program and employed a qualitative approach to a needs analysis. Interviews were conducted with two distinctly different participant groups. The first group was comprised of administrators and teacher-leaders identified by a superintendent of a rural school district in Central Florida as (")highly effective("). The second group of participants was comprised of current Ed. D. students working in K-12 education with more than 10 years' experience.This research identified specific project types that best support school improvement and should therefore be integrated into the Ed. D. in Education program as allowable project types for use as the Dissertation in Practice. The results also identified qualities of highly effective administrators and teacher-leaders that may be considered by program faculty for inclusion in the design and implementation of the curriculum for the Ed. D. in Education program.Implications of this research include using the results to inform instructional practices and the allowable DiP projects for the Ed. D. in Education program. As this study was a needs analysis that serves as a basis for program instructional decisions, the results of this study may inform other Carnegie Project on the Education Doctorate (CPED) member institutions how to modify or enhance their programs as well.The focus on this study was exclusively on K-12 education. However many students enrolled in the program work in business, government, or non-profit settings. This research could be replicated to determine improvement project types that are commonly implemented in those settings in order to better meet the needs of all students enrolled in the Ed. D. in Education program.

Show moreThroughout the many years of research examining the various effects of automation on operator performance, stress, workload, etc., the focus has traditionally been on the level of automation, and the invocation methods used to alter it. The goal of the current study is to instead examine the utilization of various types of automation with the goal of better meeting the operator's cognitive needs, thus improving their performance, workload, and stress. The task, control of a simulated unmanned robotic system, is designed to specifically stress the operator's visual perception capabilities to a greater degree. Two types of automation are implemented to support the operator's performance of the task: an auditory beep aid intended to support visual perception resources, and a driving aid automating control of the vehicle's navigation, offloading physical action execution resources. Therefore, a comparison can be made between types of automation intended to specifically support the mental dimension that is under the greatest demand (the auditory beep) against those that do not (the driving automation). An additional evaluation is made to determine the benefit of adaptively adjusting the level of each type of automation based on the current level of task demand, as well as the influence of individual differences in personality.Results indicate that the use of the auditory beep aid does improve performance, but also increases Temporal Demand and Effort. Use of driving automation appears to disengage the operator from the task, eliciting a vigilance response. Adaptively altering the level of automation to meet task demands has a mixed effect on performance and workload (reducing both) when the auditory beep automation is used. However, adaptive driving automation is clearly detrimental, causing an increase in workload while decreasing performance. Higher levels of Neuroticism are related to poorer threat detection performance, but personality differences show no indication of moderating the effects of either of the experimental manipulations. The results of this study show that the type of automation implemented within an environment has a considerable impact on the operator, in terms of performance as well as cognitive/emotional state.
