Two thoughts:
1- referring to what a few people said regarding teachers' level of
experience in the classroom compared to their level of experience with
technology, I think that it would have been much more beneficial had
Recker, Dorward, and Nelson examined both factors more in depth.
Instead of only using experienced teachers (experience being time in
the classroom) who were "comfortable" with technology (I feel unsure
of how they decided whether a teacher was qualified to be
"comfortable" - did I miss that or was it never mentioned?), I think
their argument would have been greatly strengthened if they had used a
variety of teachers (first year, second, almost-retired) with a
variety of technological capabilities/ comfortability. For example,
during my student teaching, there was a "new" teacher (in his second
year) who could do amazing things with technology and the internet and
as such was able to help his students develop a greater level of
understanding. There was also a very experienced teacher who was able
to use a little bit of technology/ the internet and would even call
himself "comfortable" with the internet, but he rarely used it to help
students build understanding at all (in fact, he would only use it for
non-math things that would entertain the students and boost their
opinion of him as a "cool teacher").
2- I really loved Janelle's response to Chris' question about how one
decides that something is worth posting on the internet. I believe
this takes us into the realm of subjectivity and opinion. Janelle
(who has a great nickname) hits the nail on the head when she says
that people post ideas that they like themselves - this gives that
information an element of worth and value, and are thus "good ideas."
How could one person say "you have a great idea" and "yours is stupid"
to every single thing that goes on the internet? It must be of some
worth or value to some person somewhere, or it would never get posted
in the first place. I certainly agree that some information is more
useful than others at given times, namely when I am looking for very
particular information or need to use it for something specific like
writing a paper, getting a source, finding local chinese restaurants,
etc... Part of the appeal of the World Wide Web is that it is
universally accessible, which includes the ability to contribute to
it. Perhaps, if we're looking for more specific information, we ought
to search specialized databases, journals, encyclopedias, and the
like. Such collections of information would certainly require
somebody to review the information to ensure its validity and
usefulness before including it, and then you would need to answer the
questions such as "who reviews it" and "what standards are the works
held to". As far as the world wide web, I think it would be
impossible and even a really bad idea to require every thing that was
ever posted to be reviewed and accepted/ rejected - what about the
right/ freedom to express oneself? (Of course, there are certain
expressions that are socially inapproriate such as nudity, vulgarity,
swear words, etc... Typically such things are kept off of easily
accessible, public domains where you would be surfing at home, school,
work, etc..., and there are available applications/ police type things
that help with this). Anyways, i think that the internet has to be
accessible and that we need to always be able to find useless things
that interfere with our scholarly/ academic/ otherwise searches for
information, how else would we be able to find distraction and
procrastine?
