A discussion of resources outside the traditional classroom, such as the internet and community service opportunities, that enhance student learning.

Whether instructional goals originate from curriculum documents, students’ expressed interests, or a mixture of both, students are more likely to achieve the goals if teachers draw on a wide variety of resources. As a practical matter, this means looking for materials and experiences that supplement—or occasionally even replace—the most traditional forms of information, such as textbooks. Precisely what resources to use depend on factors unique to each class, school, or community, but they might include one or more of the following.

The internet as a learning tool

The Internet has become a fixture of modern society, and it offers a huge variety of information on virtually any topic, including any school subject and any possible grade level from kindergarten through university. At the time of writing this book (2007), about two-thirds of all households in the United States and Canada have at least some sort of Internet access, and virtually 100 per cent of public and private schools have some access (Parsad&Jones, 2006). These circumstances make the Internet a potential major resource for teachers and students—a virtual library many times larger than even the largest physical (or “bricks and mortar”) libraries in the world.

But the vastness of the Internet is not entirely a blessing. A major problem is that the sheer volume of information available, which can sometimes make searching for a specific topic, article, or document overwhelming and inefficient. The newer search engines (such as Google at<http://www.google.com>) can help with this problem, though they do not solve it completely. When searching the term photosynthesis, for example, Google and other similar search engines return over six million web pages that discuss or refer this topic in some way! If a teacher is planning a unit about photosynthesis, or if a student is writing an essay about it, which of these web pages will prove most helpful? Choosing among web pages is a new, somewhat specialized form of computer literacy, one that can be learned partially by trial-and-error online, but that also benefits from assistance by a teacher or by more experienced peers (Ragains, 2006).

Another problem with the Internet is inequity of access. Even though, as we mentioned above, virtually all schools now have access of some sort, the access is distributed quite unevenly across communities and income groups (Skinner, Biscope,&Poland, 2003; Parsad&Jones, 2005). For one thing, the large majority of Web pages are posted in English, and this fact naturally poses a challenge for any students who still learning to read or write English. For another, schools vary widely in how much Internet service they can provide. In general, well-to-do schools and those in cities provide more access than those located in less well-off areas or in rural areas—though there are many exceptions. A richly endowed school might have an Internet connection in every classroom as well as multiple connections in a school library or in specialized computer rooms. Students as well as faculty would be able to use these facilities, and one or more teachers might have special training in Internet research to help when problems arise. At the other extreme, a school might have only a few Internet connections for the entire school, or even just one, located in a central place like the library or the school office. Usage by students would consequently be limited, and teachers would essentially teach themselves how to search the Internet and how to troubleshoot technical problems when they occur.

what is fullerene does it is used to make bukky balls
Devang Reply
are you nano engineer ?
fullerene is a bucky ball aka Carbon 60 molecule. It was name by the architect Fuller. He design the geodesic dome. it resembles a soccer ball.
what is the actual application of fullerenes nowadays?
That is a great question Damian. best way to answer that question is to Google it. there are hundreds of applications for buck minister fullerenes, from medical to aerospace. you can also find plenty of research papers that will give you great detail on the potential applications of fullerenes.

so some one know about replacing silicon atom with phosphorous in semiconductors device?
s. Reply
Yeah, it is a pain to say the least. You basically have to heat the substarte up to around 1000 degrees celcius then pass phosphene gas over top of it, which is explosive and toxic by the way, under very low pressure.
Do you know which machine is used to that process?
