The MODIS Rapid Response System generates complete mosaic images of the Arctic every day at 4km, 2km, 1km resolutions. The mosaic is composed of smaller image tiles, which are available individually at 250 m, 500 m, 1 km, 2 km, and 4 km resolutions.

A large collection of MODIS Rapid response imagery can be found in the Earth Observatory's Natural Hazards section, with captions that provide pertinent information about each image.

(1) modeling the use of new technologies in communicating to students, teachers and the general public; (2) ensuring that technology becomes integral to teaching 21st-century skills from critical thinking and problem solving to collaboration and information literacy in the classroom; (3) boosting Web 2.0 applications and tools as key components of student learning; (4) offering professional development in these technologies and deploying the online tools that help teachers create learning communities among themselves; and (5) requiring better balanced assessments of student work—including project-based learning enhanced by technology tools—in an age driven by NCLB-oriented testing and better use of data from the assessments to help students improve their performance.

The revised edition also includes a self-assessment for superintendents to evaluate how far their districts have come along the technological curve. CoSN’s CEO Keith Krueger explains that his organization’s research shows that many district leaders are behind that curve, and the new document opens with a letter:

e cautions that the large-scale changes CoSN is advocating are most likely to happen for district leaders who are not engaged in dozens of other initiatives. “Everybody wants the superintendent to be in the middle of everything,” Reeves explains. “The real acid test is whether you can execute the ‘not-to-do list,’” adding that superintendents need to resist establishing too many priorities. Each of the five areas featured in “Empowering the 21st Century Superintendent” includes a set of resources and a series of action steps for superintendents and district leadership teams. For instance, in the 21st-century skills section, leaders are urged to improve their own such skills, create a vision for integrating them into K12 instruction, audit the district’s strategic plan to see which might be missing and adjust professional development accordingly.

If you come across a question you can't answer, be honest. Don't bluff or portray yourself as an expert when you aren't. Instead model the collaborative skills you've developed and work together with the student to solve problems.

By sharing power you enhance the learning community. 

Here are some problem solving tips.

A series of studies that have had a great deal of influence on the research and decision-making discussions concerning school library media programs have grown from the work of a team in Colorado—Keith Curry Lance, Marcia J. Rodney, and Christine Hamilton-Pennell (2000).

Recent school library impact studies have also identified, and generated some evidence about, potential "interventions" that could be studied. The questions might at first appear rather familiar: How much, and how, are achievement and learning improved when . . . librarians collaborate more fully with other educators? libraries are more flexibly scheduled? administrators choose to support stronger library programs (in a specific way)? library spending (for something specific) increases?

high priority should be given to reaching teachers, administrators, and public officials as well as school librarians and school library advocates.

there may be levels of web learning maturation at work here: Childhood: people who are very new to using the web for learning tend to accept what is given to them, because they don’t really know what the options are. When online learning with the LMS was new, most people were in this category. Adulthood: people who use the web a great deal and in varied ways tend to do better in online classes, and assess the worth of the LMS (or any tool) based on how well it works for the course. Adolescence: in between are the adolescents. They know just enough to be dangerous. They have enough experience to want convenience and not enough to understand the larger issues of pedagogy, including the restrictiveness of an LMS on what the instructor wants to do. They can drive but have no sense of how traffic works.

Why it’s important to deal now with the “teen angst” of web-adolescence: 1. Not customizing the LMS to suit your pedagogy implies that we all teach the same way. If we all teach the same way, then a computer can do our work instead. (I’ve been reading Daniel Pink’s A Whole New Mind – he’s pretty clear that if a computer can do your job, eventually it will.) 2. Instructors should use the tools that best create the environment they want, and that increasingly means web applications that require multiple log-ins. Students should get accustomed to using separate tools for separate tasks, just like in the real world. 3. Acknowledging the teen view means taking it seriously, but it doesn’t mean developing policy around it. Just as parents try to mitigate the excesses of the teen diet and habits, we owe students our wisdom in creating the learning experience that is most appropriate. (Oh dear, I’m starting to sound like Edmund Burke again.)
