Assessing whether learning in one domain is transferable to abilities in other domains often eludes traditional testing. Thus, a question with bearing on the promise of neuroscience for education is whether neural changes that accompany in-school curriculum learning can improve prediction of learning transfer. Separately, debate in philosophy and p...

In an effort to better prepare students for collegiate work and the workplace, James Madison University (JMU) has created a unique, mentored dual enrollment program to help build high school students’ spatial and critical thinking skills, as well as give them in-depth experience with geospatial technologies. The Geospatial Semester, now in its 10...
Article
Full-text available
Knowledge around geospatial technologies and learning remains sparse, inconsistent, and overly anecdotal. Studies are needed that are better structured; more systematic and replicable; attentive to progress and findings in the cognate fields of science, technology, engineering, and math education; and coordinated for multidisciplinary approaches. A...

The Education and Public Outreach Panel for the 2003-2013 Decadal Survey has generated this report to assist NASA and the planetary sciences community with planning and prioritization of E/PO activities. We recognize the significant achievements of the NASA Office of Space Science (OSS) E/PO efforts in recent years which address many of the issues...
Article
Visualizing data is a great gateway to exciting mathematics and science content for many students and teachers. However, all too often, training and professional development focus on all the details of a single tool, forcing the learners to wonder what happened to the forest while they were learning all about the tree. In Project VISM—Visualization...

The “Image Processing for Teaching” (IPT) project provides a powerful medium to excite students about science and mathematics, especially children from minority groups and others whose needs have not been met by traditional “coded” ways of teaching these subjects. IPT offers open-ended opportunities for exploration, discovery, and quantitative anal...
Article
The probability distribution for impact velocities between two given asteroids is wide, non-Gaussian, and often contains spikes according to our new method of analysis in which each possible orbital geometry for collision is weighted according to its probability. An average value would give a good representation only if the distribution were smooth...
Article
Interpretation of the impact record on Asteroid 951 Gaspra requires understanding of the effects of collisions on a target body of Gaspra's size and shape. Recent hydrocode models show that major impacts on Gaspra may leave craters larger than previously thought possible and that they can create substantial regolith and produce global jolting capab...

Interpretation of the impact record on Gaspra requires understanding of the effects of collisions on a target body of Gaspra's size and shape, recognition of impact features that may have different morphologies from craters on larger planets, and models of the geological processes that erase and modify impact features. Crater counts on the 140 sq k...
Article
In order to better understand the effect of collisions on short-term features in narrow planetary rings, we have developed a model to investigate how particle-particle collisions might modify some consequences of satellite perturbations. To mimic the effect of collisional scattering, we use a Monte Carlo-like simulation that alters the velocities o...
Article
Planet formation models and simulations appear to be converging toward a consensus on how growth may have occured, at least up to the emergence of a few dominant planetary embryos from the vast swarm of planetesimals, which is similar to the scenario described by Greenberg et al. (1978, Icarus 35, 1–26). The various approaches to simulation differ...
Article
In an effort to understand the observed complex form of Saturn's F ring, we have used Gauss' perturbation equations to numerically model the short-term, three-dimensional dynamics of narrow rings. We consider ring particles that are perturbed by local moonlets orbiting with small (i ≤ 0°.1) inclination; collisions are ignored. We confirm that, as e...

The intermediate stage of protoplanetary accretion, where sub-km sized bodies accrete in 500-1000 km diameter bodies, is critical in determining the character of subsequent evolution. Greenberg et al. discovered that, at least through the formation of 500 km planetary embryos, the small particle dominate the population and control the velocity dist...
Article
Discoveries over the past fifteen years have revolutionized our understanding of planetary rings. Until recently, the only known ring system was Saturn's elaborate one, first spied by Galileo in 1610, but in 1977 rings were detected about Uranus. Shortly after that, rings were found about Jupiter (1979) and Neptune (1984), demonstrating that all of...
Article
The Saturn F ring's shepherd satellites, Pandora and Prometheus, have been suspected of causing the periodicities observed in the ring. To test this idea, a selection of the best available Voyager images of the ring were examined by applying an FFT technique to azimuthal profiles from spacecraft ring images. Only a few distinct periodic signals, in...
Article
The narrow width of Saturn's F ring belies its dynamical complexity. The kinks, clumps, and braids discovered by the Voyager spacecraft give the ring an ever-changing appearance when viewed at different times or from different orientations. In an attempt to quantify the longitudinal variations of the F ring in detail, a suite of Voyager 1 and 2 ima...
