A model for developing and disseminating multimedia materials for teacher educators.
Date: December 2002
Creator: Hodges, Linda S.
Description: The purpose of this study was to develop a model that would enhance the development, dissemination, and adoption of educational multimedia materials. The grounded theory definition of open coding was used to analyze data collected from the 3-year Technology Leadership Web Library Project at the University of North Texas. Weekly meeting minutes, email communication, reports, notes, questionnaires, and surveys were examined to determine major factors involved in the process of product development and dissemination. From the analysis of this study, five major factors in product development and dissemination were identified. These factors were leadership, team dynamics, expert advisors, feedback, and consumers. The synthesis of the factors led to the development of the PROMOTE (process revolving around ongoing management of team and evaluative feedback) model. The PROMOTE model is based on the establishment of a system that includes leadership, development team, and expert advisors at its center. The system is tied together with well-established feedback loops for stages of evaluation. The PROMOTE model is iterative and uses consumer feedback to generate new products. The PROMOTE model differs from other product development and evaluation models both in the focus of the process and the nature of the evaluation feedback.

Toward a functional approach to goal setting
Date: December 2007
Creator: Isley, Shane D.
Description: A variable that may be associated with performance improvements is goal setting (within and across days). Easy-to-achieve goals will likely produce gradual trends in improvement and difficult-to-achieve goals steeper trends. The purpose of the current experiments was to study the effects of setting easy-to-achieve and difficult-to-achieve goals on the level, trend, and variability of correct, incorrect, and skip responses for math tasks when reinforcement contingencies and numbers of practices were held constant. Five undergraduate students answered math problems on flash cards in 30s timings. Single case design elements were used to evaluate the effects of different types of goals on the speed and accuracy of performance. The results revealed that goal setting primarily increased the frequency of incorrect responses and both the level and trend of skip responses. The implications of these findings and other important variables that influence the effectiveness of goal setting are discussed. In addition, the authors suggest guidelines to follow when implementing goals to improve performance.

The effects of a feedback package on the facial orientation of a young girl with autism during restricted and free operant conditions
Date: August 2000
Creator: Jacobs, Wendy Lynn
Description: A multiple baseline design across activities and people was used to assess the effectiveness of a feedback package on the facial orientation of a young girl with autism. During baseline, observations indicated low rates of facial orientation and high rates of gaze avoidance during conversation (restricted operant) and play (free operant) conditions. After treatment, facial orientation rates increased and gaze avoidance rates decreased to levels similar to typically-developing peers and maintained at one month follow up. These results suggest that the feedback package was effective in producing durable facial orientation across different environments and people. Possible interpretations, strengths, and limitations are discussed.

Teacher Training: An Examination of Skill Acquisition, Generalization, and Increases in Child Appropriate Behavior
Date: August 2000
Creator: Sawyer, Rebecca Jo Moore
Description: The effects of a training package (modeling, role-playing, and feedback) were evaluated using a multiple baseline across skill areas. Two trainers taught two teachers to use basic intervention skills that included components of both discrete trial teaching (DTT) and the Natural Language Paradigm (NLP). Training occurred in the context of one task. Generalization was assessed with two untrained tasks. Teachers' responses in the target task increased following training, as did appropriate responding from the child. Some generalization of the teaching skills occurred. Teachers were instructed to generalize acquired skills as a possible method to promote generalization. The results of these findings and implications for training of ABA providers are discussed.

Effects of goal setting, e-mail feedback and graphic feedback on the productivity of public school attendance clerks
Date: August 2000
Creator: Rexroat, Robin D.
Description: A package intervention, consisting of daily-adjusted goal setting, e-mail feedback, and graphic feedback, was used in a public school attendance office to increase the efficiency with which 3 attendance clerks documented student attendance. During the intervention phase, the attendance secretary set a daily goal for each attendance clerk. This goal was a percentage of student absences to be coded and entered in the school computer program. After establishing a daily goal, the attendance secretary provided daily feedback, in the form of a written e-mail response and graphed feedback to each clerk. If the subjects had attained their daily goal, the attendance secretary also delivered a praise statement along with the e-mail feedback. Results indicated that the intervention package was ineffective in producing change in the attendance clerks' absence coding behavior.

Computer virus spread containment using feedback control.
Date: December 2004
Creator: Yelimeli Guruprasad, Arun
Description: In this research, a security architecture based on the feedback control theory has been proposed. The first loop has been designed, developed and tested. The architecture proposes a feedback model with many controllers located at different stages of network. The controller at each stage gives feedback to the one at higher level and a decision about network security is taken. The first loop implemented in this thesis detects one important anomaly of virus attack, rate of outgoing connection. Though there are other anomalies of a virus attack, rate of outgoing connection is an important one to contain the spread. Based on the feedback model, this symptom is fed back and a state model using queuing theory is developed to delay the connections and slow down the rate of outgoing connections. Upon implementation of this model, whenever an infected machine tries to make connections at a speed not considered safe, the controller kicks in and sends those connections to a delay queue. Because of delaying connections, rate of outgoing connections decrease. Also because of delaying, many connections timeout and get dropped, reducing the spread. PID controller is implemented to decide the number of connections going to safe or suspected queue. Multiple ...

Improving management systems in a public school in-home autism services program.
Date: December 2006
Creator: White, Victoria Anne
Description: The purpose of this study was to develop and examine the effects of enhanced training and performance management methods for an autism coordinator who managed several paraprofessional therapists providing in-home behavior therapy for young children with autism. Intervention included task clarification, targeted skill development, and improved feedback from the coordinator to the therapists. Results showed that service delivery performance of in-home trainers increased and/or became more consistent after the intervention was implemented. The intervention provided the autism coordinator with an empirically validated training and feedback system that can be successfully utilized in a sporadically supervised environment.

Performance measurement, feedback, and reward processes in research and development work teams: Effects on perceptions of performance
Date: December 2000
Creator: Roberts, M. Koy
Description: Organizations have had difficulty managing the performance of their knowledge work teams. Many of these troubles have been linked to antiquated or inadequate performance management systems along with a scarcity of empirical research on this important human resource initiative. These problems are magnified when managing the performance of research and development teams because greater ambiguity and uncertainty exists in these environments, while projects are unique and continually evolving. In addition, performance management in R&D has only recently been accepted as important while individuals in these settings are often resistant to teams. This study represented the first step in the process of understanding relationships between performance management practices and perceptions of performance in R&D work teams. Participants were 132 R&D team leaders representing 20 organizations that agreed to complete a survey via the Internet. The survey instrument was designed to examine the relationships between performance measurement, feedback, and reward processes utilized by teams in relation to measures of customer satisfaction, psychological and team effectiveness, and resource utilization and development. The most important level of performance measurement occurred at the business unit level followed next by the individual level while team level measurement was unrelated to team performance. A simple measurement system ...

Control of chaos in a CO2 laser
Date: September 5, 1994
Creator: Pérez, José M.; Steinshnider, J.; Stallcup, Richard E. & Aviles, A. F.
Description: This article discusses the control of chaos in a CO2 laser. Abstract: We report the experimental control of chaos in an optically modulated CO2 laser. The CO2 laser was driven into chaos by injecting a feedback beam modulated by an electro-optical modulator. Control of chaos was achieved using a modified proportional feedback technique in which the control pulses were delayed by approximately one relaxation period. Using this technique, it was possible to control unstable periodic orbits up to period 6.
