Compilation and development of K-6 aerospace materials for implementation in NASA spacelink electronic information system

Spacelink is an electronic information service to be operated by the Marshall Space Flight Center. It will provide NASA news and educational resources including software programs that can be accessed by anyone with a computer and modem. Spacelink is currently being installed and will soon begin service. It will provide daily updates of NASA programs, information about NASA educational services, manned space flight, unmanned space flight, aeronautics, NASA itself, lesson plans and activities, and space program spinoffs. Lesson plans and activities were extracted from existing NASA publications on aerospace activities for the elementary school. These materials were arranged into 206 documents which have been entered into the Spacelink program for use in grades K-6

Principals\u27 Perceptions of the Effectiveness of the JROTC Program

The purpose of this national study was to investigate the perceptions of public high school principals regarding the effectiveness of the Junior Reserve Officer Training Corps (JROTC) program. The study examined the perceived influence of the program regarding the social development of the cadet, the behavior of the cadet, and the overall school environment. Data for this study was collected through an anonymous online survey emailed to current principals in public high schools across the United States where JROTC is offered as a course selection. Of the 3,062 schools identified as the population, 491 usable surveys provided participant information for data analysis. Principals indicated their level of agreement; from strongly disagree to strongly agree, regarding the perceived effectiveness of the JROTC program influence related to three constructs: social development of the cadet, behaviors of the cadet, and school environment. Responses were also compared based on demographic data related to the principals and to the schools. Findings indicated that high school principals perceived participation in the JROTC program as having a positive influence on the cadets’ social development, cadets’ behaviors, and on the overall school environment. Additionally, the study concluded that the strongest concentration of statistical significance based on demographics appears in the items measuring cadets’ social development. Findings resulting from the quantitative data and qualitative data, collected by open ended survey questions, suggest that the JROTC does more than merely prepare students for a successful military career. Findings from this study suggest that principals in schools with JROTC find the program to be effective in helping cadets meet goals and satisfy needs

Updating and augmenting NASA spacelink electronic information system

NASA's Spacelink is a collection of NASA information and educational materials stored on a computer at the Marshall Space Flight Center (MFSC). It is provided by the NASA Education Affairs Division and is operated by the Public Services and Education Branch of the MFSC Public Affairs Office. It is designed to communicate with a wide variety of computers and modems, especially those most commonly found in classrooms and homes. The system may be accessed by the educators and the public over regular telephone lines. NASA Spacelink is free except for the cost of long distance calls. The material prepared for Spacelink was found to be widespread by teachers and others across the nation and is being used to stimulate students in their quest for excellence. A partial summary of Spacelinks usage is presented

Augmenting and updating NASA spacelink electronic information system

The development of Spacelink during its gestation, birth, infancy, and childhood are described. In addition to compiling and developing more material for implementation in Spacelink, Summer 1989 was spent scanning the insignias of the various manned missions into Spacelink. Material for the above was extracted from existing NASA publications, documents and photographs

Refining, revising, augmenting, compiling and developing computer assisted instruction K-12 aerospace materials for implementation in NASA spacelink electronic information system

The NASA Spacelink is an electronic information service operated by the Marshall Space Flight Center. The Spacelink contains extensive NASA news and educational resources that can be accessed by a computer and modem. Updates and information are provided on: current NASA news; aeronautics; space exploration: before the Shuttle; space exploration: the Shuttle and beyond; NASA installations; NASA educational services; materials for classroom use; and space program spinoffs

Updating and expanding the library of materials on NASA Spacelink electronic information system

NASA Spacelink, a proven resource medium, may be accessed over telephone lines or via the Internet by teachers or anyone with a computer or modem. It is a collection of historical and current information on NASA programs and activities. Included in this library is information on a variety of NASA programs, updates on Shuttle status, news releases, aeronautics, space exploration, classroom materials, NASA Educational Services, and computer programs and graphics. The material stored in Spacelink has found widespread use by teachers and others, and is being used to stimulate students, particularly in the area of aerospace science

Overhauling, updating and augmenting NASA spacelink electronic information system

NASA/Spacelink is a collection of NASA information and educational materials stored on a computer at the MSFC. It is provided by the NASA Educational Affairs Division and is operated by the Education Branch of the Marshall Center Public Affairs Office. It is designed to communicate with a wide variety of computers and modems, especially those most commonly found in classrooms and homes. It was made available to the public in February, 1988. The system may be accessed by educators and the public over regular telephone lines. NASA/Spacelink is free except for the cost of long distance calls. Overhauling and updating Spacelink was done to refurbish NASA/Spacelink, a very valuable resource medium. Several new classroom activities and miscellaneous topics were edited and entered into Spacelink. One of the areas that received a major overhaul (under the guidance of Amos Crisp) was the SPINOFFS BENEFITS, the great benefits resulting from America's space explorations. The Spinoff Benefits include information on a variety of topics including agriculture, communication, the computer, consumer, energy, equipment and materials, food, health, home, industry, medicine, natural resources, public services, recreation, safety, sports, and transportation. In addition to the Space Program Spinoff Benefits, the following is a partial list of some of the material updated and introduced: Astronaut Biographies, Miscellaneous Aeronautics Classroom Activities, Miscellaneous Astronomy Classroom Activities, Miscellaneous Rocketry Classroom Activities, Miscellaneous Classroom Activities, NASA and Its Center, NASA Areas of Research, NASA Patents, Licensing, NASA Technology Transfer, Pictures from Space Classroom Activities, Status of Current NASA Projects, Using Art to Teach Science, and Word Puzzles for Use in the Classroom

RAP: Risk-Aware Prediction for Robust Planning

Robust planning in interactive scenarios requires predicting the uncertain future to make risk-aware decisions. Unfortunately, due to long-tail safety-critical events, the risk is often under-estimated by finite-sampling approximations of probabilistic motion forecasts. This can lead to overconfident and unsafe robot behavior, even with robust planners. Instead of assuming full prediction coverage that robust planners require, we propose to make prediction itself risk-aware. We introduce a new prediction objective to learn a risk-biased distribution over trajectories, so that risk evaluation simplifies to an expected cost estimation under this biased distribution. This reduces the sample complexity of the risk estimation during online planning, which is needed for safe real-time performance. Evaluation results in a didactic simulation environment and on a real-world dataset demonstrate the effectiveness of our approach.Comment: 23 pages, 14 figures, 3 tables.
