Action Research on team teaching style and workload for elementary school teachers

Huang, Chien-yuan 14 June 2010 (has links)
The study aims to release how to make the researchers willingly to devote their efforts to teaching continuously. On one hand, the teaching qualities will be enhanced. on the other hand, the mental and physical fatigue will be reduced. In order to achieve the objectives of this study, the study adopts action-research and on the theory of team teaching finds out what degree of the workload of every team-teaching style. The distinction of the study is that team teaching in formal and nonformal curriculum, and implementation of five styles of team-teaching after six-years period. These participants are spontaneous, they are also the subjects in research. On the basis of the observation , the questionnaire, analysis of the teaching miscellanies and reflection. The study is vertufied and received the feedback. Then it becomes the basis for next action. ¡]1¡^Exchange teachers team-teaching The difficulty of implementation is the minimum, beacause the workload of teaching preparation can be reduced. But the feelings of workload is increasing ¡]2¡^Dynamic team-teaching It is moderately difficult to implement. The workload of teachers can be reduced to higher degree. But it is fatally flawed in parents¡¦ questioning. ¡]3¡^Group team-teaching It is moderately difficult to implement, too. Athough it is not the best model to reduce the workload, it still can ease the workload to a degree. ¡]4¡^Single-core team-teaching It is more difficult to implement. It can reduce the workload somehow, but in terms of teaching preparation alone, it almost makes no differences between before and after. So the feelings of workload did not significantly change. ¡]5¡^Multi-core team-teaching Overall it is the most difficult to implement for a long time. It also can reduce the workload, especially the researchers ,but multi-core membership is fragile. ¡]6¡^ The impact on these five team-teaching styles of teaching workload is different. Multi-core team-teaching meet the researchers¡¦ requirements mostly, but Group tem-teaching is much more advantageous to implement in the real environment.

Motivation among NASA government contractors

Garcia, Yadira 2009 August 1900 (has links)
There are many government standards and regulations that even contractors must follow. This makes it difficult for contracting companies to have the same incentives that other private companies provide for their employees that keeps them motivated. A survey was conducted among NASA government contractors, mainly Engineering and Science Contract Group (ESCG) contractors to get their perspective on the work motivation they have working in the space industry. This report will discuss some of the motivation theories proposed in industrial psychology as well as the benefits offered by ESCG and will be compared with the results from the survey. Lastly there will be recommendations on how to improve the benefits offered or lack thereof by ESCG that could improve the motivation in the workplace. / text

APPLICATION OF ADAPTIVE COMPUTING IN SATELLITE TELEMETRY PROCESSING

Figueiredo, Marco, Graessle, Terry 10 1900 (has links)
International Telemetering Conference Proceedings / October 26-29, 1998 / Town & Country Resort Hotel and Convention Center, San Diego, California / The advent of adaptive computers built from re-programmable logic devices presents a potential solution for meeting the data processing requirements of the new era of Earth monitoring satellites to be launched by the National Aeronautics and Space Administration (NASA) Earth Science Enterprise project. The Earth Observing System (EOS) AM-1 spacecraft, the first satellite of this new era, will produce in only six months as much data as NASA has collected to this date. As a consequence, the Earth Science Data and Information System (ESDIS) project is building high performance and highly costly parallel processing systems to address the real-time data production requirements. Together with the high performance front-end ingest and level 0 processing microcircuits developed in-house at the Goddard Space Flight Center’s (GSFC) Data Systems Technology Division (DSTD), adaptive computers present a possible alternative to traditional CPU-based systems to increase the performance while reducing the cost of satellite telemetry processing systems. The Adaptive Scientific Data Processing (ASDP) project has been investigating the use of adaptive computers in the implementation of space borne scientific data processing systems. An order of magnitude processing speed acceleration over high-end workstations has been demonstrated for both level 1 and level 3 algorithms. This paper discusses the use of adaptive computing in satellite telemetry processing systems, level 1 and beyond. Primarily, it describes the efforts and presents the results of two prototypes developed by the ASDP project. The limitations of the current state of the technology are discussed and the expected improvements to facilitate the adoption of adaptive computers are presented. Finally, future work of the ASDP project is discussed.

Application of IP Multicasting to the NASA Communications Command and Telemetry Ground Network

Spinolo, M. Chris 10 1900 (has links)
International Telemetering Conference Proceedings / October 26-29, 1998 / Town & Country Resort Hotel and Convention Center, San Diego, California / The NASA Communications (Nascom) Division has been directed to deploy Internet Protocol (IP) based technology for the ground segments of all present and future spaceflight telemetry networks. The Nascom network supports all NASA spaceflight telemetry, command and status requirements, from sounding rockets and balloons to the Hubble Space Telescope and the Space Shuttle. This paper discusses the challenges of transitioning a 35 year old, custom engineered, worldwide legacy telemetry network to IP, and the resulting, new NASA IP Operational Network for ground transport of spacecraft telemetry and command.

Network Management and Signalling Standards for CCSDS Advanced Orbiting System Communication Systems

Pietras, John 11 1900 (has links)
International Telemetering Conference Proceedings / October 30-November 02, 1989 / Town & Country Hotel & Convention Center, San Diego, California / The Consultative Committee for Space Data Systems (CCSDS) is an international organization chartered to develop and adopt communications protocols and data processing standards suitable for use in space-related communication and data processing systems. Among its ongoing activities, CCSDS is in the final stages of approving recommendations for communications services and protocols to be used by "advanced orbiting systems" (AOS) typified by the international Space Station Freedom Program. As a companion activity to the development of the AOS protocols, CCSDS is in the process of defining the network management functions that are necessary to realize the full capabilities of the AOS services. CCSDS is also concerned with communicating management information among distributed network management systems, an environment that will be typical of multi-national space ventures. These network management systems are envisioned to be automated, resulting in a need for standard network management protocols and data structures. This paper briefly describes the CCSDS network management environment, and reviews the current status of CCSDS recommendations for network management functional capability, use of international standards for network management, and composition of signalling systems in support of the AOS services. The paper concludes with a timetable for future work in this area.

REDUCING MAINTENANCE COSTS ON THE SHUTTLE PROGRAM

Gladney, Ed 10 1900 (has links)
International Telemetering Conference Proceedings / October 28-31, 1996 / Town and Country Hotel and Convention Center, San Diego, California / NASA and Lockheed Martin Telemetry & Instrumentation have jointly developed a new data acquisition system for the Space Shuttle program. The system incorporates new technologies which will greatly reduce manpower requirements by automating many of the functions necessary to prepare the data acquisition system for each shuttle launch. This new system, the Automated Data Acquisition System (ADAS), is capable of configuring itself for each measurement without operator intervention. The key components of the ADAS are the Universal Signal Conditioning Amplifier (USCA), the Transducer Electronic Data Sheet (TEDS), and the Data Acquisition System (DAS 450). The ADAS is currently being delivered and installed at Kennedy Space Center. NASA and Telemetry & Instrumentation are actively pursuing commercialization of the ADAS and its associated products which will be available during 1996.

Skylab: The Human Side of a Scientific Mission

Johnson, Michael P. 05 1900 (has links)
This work attempts to focus on the human side of Skylab, America's first space station, from 1973 to 1974. The thesis begins by showing some context for Skylab, especially in light of the Cold War and the “space race” between the United States and the Soviet Union. The development of the station, as well as the astronaut selection process, are traced from the beginnings of NASA. The focus then shifts to changes in NASA from the Apollo missions to Skylab, as well as training, before highlighting the three missions to the station. The work then attempts to show the significance of Skylab by focusing on the myriad of lessons that can be learned from it and applied to future programs.

Medical Hardware for the Space Environment: An Engineering Experience at the National Aeronautics and Space Administration

Reyna, Baraquiel 2011 August 1900 (has links)
The complexity and amount of medical hardware needed by National Aeronautics and Space Administration (NASA) constantly shifts with mission requirements. Early missions such as Mercury, Gemini, and Apollo required minimal, relatively non-complex medical hardware, but as mission lengths have increased from hours to multiple months and mission crew sizes have increased from one to seven, so has the amount and complexity of medical hardware. As such, a need has arisen to develop a methodology by which medical hardware is certified for the space environment in a safe, consistent, and economically viable manner. This record of study documents my experiences certifying medical hardware for the space environment by providing two specific certification examples, a defibrillator, and automated external defibrillator and provides a brief history of the medical hardware used by NASA for its manned space programs.
