a) It took me about 30 minutes to fully review this site. I went in and out of each links, spending more or less time on a topic that interested me or less, or I spent more time on topics that I didn't know what they were. For example, the section titled "The Planimeter" was about a mathematical tool that I hadn't previously heard of, so I spent more time there than I had for "Chinese Handcuffs". b)I think that the site does a good job at explaining concepts. In fact that is likely it's strongest point, which is that it accurately (at least to the best of my knowledge) conveys information in such a logical manner. Concerning how educationally significant they are, I think the writer of the site sort of takes away from that by explaining in the very first paragraph that he doesn't feel the need to relate these mathematical concepts to students every day lives. True, that not everything can be related. But it takes away from any possible building interest to read that as a student. So yes, the materials are educationally significant, in the way that all things can be significant, but the author is unable to show students why/how this is important to them. c)Certainly if a student were doing a report on any of these topics, or if a teacher would like to give students additional resources to review on their own, this would be a good site for that. It's very well written and concepts are explained very clearly, in my opinion. I especially think that the way concepts and topics are clearly organized, which always makes for better teaching/learning. Too often do educational website become too muddled and confusing with poor page design, which ultimately intimidates students. d) The material is easy to use, and the files or Geometer's Sketchpad aren't extremely large files, so the typical student's laptop should be able to download it with ease. Like said before, concepts are explained well and topics are organized, so it's impossible to get lost or confused amongst the materials.

I spent about two hours looking over the links on this site, going though them
and trying out the interactive ones. Here are the ones I found to be interesting
to me: The Sliding triangle, Linkages, The Planimeter, The Reuleaux and
Inversion Geometry.
I found this site to be fun and interesting at the same time, an interactive
site that is educating and fun. I checked out about a dozen of the lessons and
had fun trying out the interactive ones. I think this it a good site for young
and old students and a good teaching site. The site explains the problems and
shows you how to visualize the concept of it to, this is a good way to show what
the out come is of the problem and how easy it is to grasp the concept of it.
This is a very easy to use and is a very well designed site with descriptive,
interesting visual effects, interactive perspective drawings and more. I find
that using this types of visual effects not only help you to learn, it helps to
make it more fun for the person learning or teaching.

I took a look at this website more than one time before deciding to add a
comment. I spend approximately 2 1/2 hours total time on site- my first visit
for about an hour and my second visit 1 1/2 hours.What initally attracted me was
how Kunkel interacted with his dialog in a witty and informative style.He
refers to this website as presenting "mathematic investigation" I thought it was
exploritory in nature and invites curiousity. Some sections were very detailed
and held my interst more so then others, I spent some time on: Chinese
handcuffes; The Sliding triangle; The Brachstochrome; and Rungs and Vineyards.
Rungs & Vineyards was my favorite it's about the visial illusion exxperienced
while traveling in a car and passing a vineyards.
Kunkel uses Sketchpad to enhance his examples- I don't have this program on the
computer I using but was still able to appreciate the examples give. Overall, this site
was easy to use and I enjoyed it.

Kunkel's Mathematics Lessons is the prefect place to go if you love to draw or
are just interested in the geometric designs. "Rungs and Vineyards" is a must
see when going to this site. after about 20 mins or so It started to remind me
of when I would vist my Grandparent's house in Watsonville and as we would drive
by all of the farming crops along side the road, this site gives you two
perspective drawings that you would see from a moving automobile. It was
interesting to see an over view look of what you would be able to see from an
observer point of view. This site was full of math equations that could turn you
in circles but with a remarkable view of nature in the idea of mathematics

The site took me approximatelly forty-five minutes
to review the materials. The lessions are illustrated very remarkable by interesting arts and graphics which hepl the lessons more understanding and allurring. The materials were written clear ,well explaination, and reliable. The structure of the site is simple and organized, so it is easy to access. On the Paul Kunkel's home page lists alot of useful mathematics links. The Kunkel's mathematics lessions are very effective for eduacational purpose.

I found many of the concepts and theories interesting. I spent about twenty minutes
browsing the site. I think some of the
information could be useful for both students and teachers.
Unfortunately,I have never taken Calculus, therefore it was difficult for me to
understand some of the concepts and equations, etc.
And although I am not as familiar with some of the terminology of the material,
I still found much of the material presented fascinating.
