In this way, they will be gently walked through what is a very new process with potentially unfamiliar data remotely-sensed images of Earth. For EarthKAM this means changing the nature and distribution of the support materials. Previously, EarthKAM produced a single, comprehensive educator guide with good information and support, but it was too much for new participants to digest easily. Also, as we scale up, almost all EarthKAM materials will be available exclusively on the Web. Although this web distribution option may not be feasible for many projects, it makes sense for EarthKAM, which already requires reliable web access for participation, and it dramatically reduces the costs and difficulties of distributing materials.
Accessibility is more than just having the materials and resources available to everyone.
It is tailoring these materials and resources to help participants successfully move into the program. By supporting participation at the Public Level, we reach many more people, have a greater impact on learning, and help middle school teachers and students develop the skills they need to become more involved. Again, by layering the challenges involved in a program, teachers and students can more easily move further into it. As they develop the necessary skills and interest, new opportunities and support need to be provided. The Public Level, a worthwhile experience in and of itself, also serves middle schools as an entryway into the Community Level, which demands more of learners in terms of image analysis, inquiry, communication, and web use.
