Curriculum Web and Technology
A good curriculum web should have all the elements of a traditional classroom project. It should have clear goals and objectives that tie into the academic standards. A curriculum web is an excellent opportunity to design a project that gets students engaged in the material in a way that is relevant to them. What it should not be is an excuse to get students working on computers just for the sake of it. Children today spend enough time on computers as it is.
Evaluating Websites
I'm constantly researching things online, and I almost in a subconscious manner evaluate the credibility of the source. Obiously, if the website is from an establish news source, professional journal, etc. then you can trace the credibility back to that of the provider. With such websites you still have to use the questioning eye that is appropiate to judge traditional media.
In many other cases, however, the author is a private individual, and then you have to scrutinize the content with a more suspicious eye. Firstly, I look at whether or not the person is trying to sell me something or otherwise profit from their website. In the case that they are, everything must be taken with a grain of salt, and I try to look for neutral sources to confirm or deny that which I find to be important. Even when it is a neutral source, I have to evaluate what credentials and expertise that the author has to speak about the topic with any authority. Also I judge if they are someone who is very strongly opionated, and thus might tend to slant the truth.
Wikipedia is of course a great source to find general information about just about anything. The built in process of peer review is very effective, but it is critical to go back to the cited sources for anything that is questionable or controversial.

Math Website Evaluation
I tried several times using programs from the virtual manipulatives archive in the classroom.

Plagiarize This
I first studied copyright law in an undergraduate course on law and economics. Economically speaking, copyright law should encourage a balance between the socially optimal levels of innovation, versus the availability of intellectual/artistic material to the public. Copyright law encourages innovation by ensuring that author's receive due credit for their work, financially or otherwise. Overly restrictive copyright law, however, would inhibit innovation by stifling the spread of information.
When considering how copyright law applies to the field of education, special attention must be given to the proliferation of educational material for students. This is why the "fair use" doctrine is so important. As it applies to the classroom, the fair use doctrine allows copyrighted material to be shared to a group in such a manner that would otherwise be illegal. In the long term this is essential to promoting innovation because a more educated society is all the more capable of coming up with new insights that lead to the exponential growth in human knowledge.
Financially, copyright protection grants an author monopolistic power over his or her work, much like patents do. As such, the author can reap profits from his work that would not otherwise be possible. Sometimes this power can go to far, as currently occurs in the educational textbook industry. A few large companies dominate the educational publishing business and use their market power to gauge excess profits from students. This power gives rise to some of the shady practices in the industry, such as coming out with a new edition that is only a few words different from the previous one, just so old copies will have to be retired and students will have to purchase them new. I would like to see educators and students fight this specific practice by demanding more compatibility between textbook issues, so that an old edition could be functional with copied updates to keep up with new editions. Especially in subjects where current updates are not very essential (i.e. level I Calculus is not going to change very much in the next few years) it is a wasteful practice to constantly come out with new editions. Wherever such inefficiencies occur, copyright law should adapt to accommodate for the greatest net benefit to society.

First Blog
This is my first blog for the Advanced Technology in Education class. This will be a good class to refine computer skills and learn how to use technology in the classroom. As a math teacher I think this will be a very helpful class to come up with exciting ideas that I can use with my students.
