Sharing Data Over a Network In addition to saving placemarks or folders to your local computer, you can also save place data to a web server or network server. Other Google Earth users who have access to the server can then use the data. As with other documents, you can create links or references to KMZ files for easy access. Storing a placemark file on the network or on a web server offers the following advantages: Accessibility - If your place data is stored on a network or the Web, you can access it from any computer anywhere, provided the location is either publicly available or you have log in access. Ease in Distribution - You can develop an extensive presentation folder for Google Earth software and make that presentation available to everyone who has access to your network storage location or web server. This is more convenient than sending the data via email when you want to make it persistently available to a large number of people. Automatic Updates/Network Link Access - Any new information or changes you make to network-based KMZ information is automatically available to all users who access the KML data via a network link. Backup - If for some reason the data on your local computer is corrupt or lost, you can open any of the KMZ files that you have saved to a network location, and if so desired, save it as a local file again. Note: Before you can create a network link to an item in Google Earth, you must first store that place data on a server.

See, when you're at the front of a wired classroom, you get to watch students peck at laptops, skitter their eyes over screens and, every now and then, toss a glance in your direction. Some of them are taking notes, some are chatting with friends or cruising sports sites. Few are giving their instructor undivided attention. It's crazy making.

one of the things we ported over to new media from traditional media was the notion of the passive audience.

that chittering back channel itself isn't the problem. The problem is, as instructors, we haven't given it anything useful to do. "Students are telling us they want to be engaged. So, we need to find a way to give them specific focus for that back channel. If they're doing stuff that's on-task we're going to get engaged learning and ownership," she says.
