Authors note: My name is Erik Heinemann. I have a Bachelor’s degree in Chemistry and
teach the subject on the high school level in
Exemplar websites
The first
is the website URL http://web.jjay.cuny.edu/~acarpi/NSC/index.htm
From the
“~acarpi” it is evident that this is a personal page,
but it is a page with an individual associated with education from the edu domain. The
purpose of the site is immediately clear in that it is to educate and inform
its readers on the procedure of writing and balancing chemical reactions. The author is a professor at the
A link
to his personal information was provided but was not up to date and did not
work.
The site
was created in the 1998-1999 school year, but the chemistry information has not
changed and is still good for current students.
Links to
Periodic tables and simulations for the water formation are present as well as
other links if one was to examine the other lessons in the index. These links provide an interesting, fun and
often animated selection of information on the topic in the lesson and are
valid and reliable as far as I can tell given my years of education on the
subject of chemistry.
After
using Google to perform a link search, I found 18 sites that link to this one;
one from the
The site
is presented in a silly, but serious tone and is a GOOD site for the
educational purpose of learning about chemical reactions. It even goes so far as to provide examples
for students to practice.
The second site was not so good for chemical
reactions. The URL is
http://home.att.net/~lfretzin/notes08.html
From the “~lfretzin”
it is evident that it is a personal site. The domain is .net, but there is
little information that can be ascertained from the URL. The site provides no links and no information
about the author. The purpose of the
site seems to be informational or educational.
No date could be found. No links
are found on the entire page as far as supporting information, sources etc.. When a Google
search was performed there were no other sources that could be found that link
to this site.
The information is valid from my experience in
chemistry, but this site is POORLY linked and poorly supported. Without the supporting information, the site
cannot be authenticated and someone without the background in chemistry would
be advised not to use it for that reason; even though the information is valid.
