i enjoyed the whole visualization portion of the problem and understood what was asked...the problem was i dont know what all the symbols and other types of things were. Its visualizations and animations such as these that actually get me more interested in the problem rather than conventional teaching.

The materials seem interesting but, I don't understand how this is helpful in the real world.Overall, I thought this topic was boring and useless.The content was good and easy to understand,to whomever wants to use it.Who ever wants to learn this, it would be helpful for them.The materials that were being used in here was very well organized and explained.

I'm not to familiar with the mathematical terms they had offered. But reading them, I understood when the animation gave me a visualization. I could follow it, without being confused. It was accurate enough for me a first time user, to understand the basic meaning of it. This would be very helpful to students and teachers, it could teach them a lot and benefit them.It never seemed hard for me to understand, this site just offered a easy way to learn. This site was made for first time users,everything is there and its so simple.

Technical Remarks:

It was interesting to read, and follow along on the animation.
Time spent reviewing site: 2 hours 5 minutes.

I thought that this was a good site because it has a lot of pictures and graphs for those people who learn on a visual level. The animation is particularly useful because it let's you see how the activity is applied in real time.

Technical Remarks:

I was surprised that for a website that uses animation there were no time lags and the load time was quick. The topics were organized in a neat manner as well.
Time spent reviewing site: I spent twenty minutes looking at the different images.

a) I basically searched around because it was interesting to me that it was a JAVA applet which illustrated a mathematical analyst of the bouncing of a ball. Other than that I was observing it more and more to figure out what mathematical terms does it relate to. b) The quality of the content is good because of the graphics and the design of the demonstration of the ball. What caught my attention was the timer or the clock which was used during the demonstration. c) The effectiveness for teaching is pretty good because the material can be used by an instructor to enrich a lecture or can be assigned to students for individual perusal. It may be used to enhance students' understanding of functions. The height of the bouncing ball, plotted against time, is a series of parabolas. This gives a nice and natural example of a function that analytically must be defined piece-wise. d) Using this material was easy because the JAVA applet was self-explanatory and easy to follow. Very good tool for graphic functions and can be used in the category of Calculus.

I spent about 20 minutes reviewing the different animation regarding "How the Ball Bounces". The quality of the animation was good. The animation showed a ball bouncing with a chart that displayed time, height, and velocity. This representation was then used to show how the values correspond to algebra. I believe the visual element of animation would provide as an effective tool in learning. By connecting the numbers to each bounce of the ball a better understanding can be achieved. The ease of viewing the computer animation cannot be understated. Great visual site.

the videos ilusstrating for the problems are in good quality.

Technical Remarks:

Although it is the matter of Calculus, I find it exciting and amusing. I spent 30 minutes thinking about this problem. I have never though about Mathematics applied in a bouncing ball. With a bouncing ball, people can find the motion equations: one of position, and the other of velocity. Moreover, it is a kind of applied Math in Physics problem: Falling the ball to find the position, velocity, and acceleration, right? I studied all these stuffs in high school, but they have been unreachable for me since then. Now, I understand a little bit. It is a good new, is it not???

This animation reminds me the same expriement we did in Astronamy class. The bouncing ball is gradualy slow down, and a stright line finally shows up due to the gravity of the earth. However, if it were in space, then this movement will go forever.

. How you reviewed the materials (Did you spend 5 minutes browsing, 2 hours
trying it, or actually use it in teaching-learning activities?).

I spent about 15 mins. at this website and then something happened and my
computer crashed.

2. The quality of content (Does the materials accurately present concepts and
models that are educationally significant?)

I found the website to be fun. It is a great visual tool. It will help those
who learn by doing or learn by seeing.

3. The potential effectiveness for enhancing teaching and learning (If used
appropriately, will students' learning and faculty's teaching be enhanced?) It
defintely a effective learning tool for both teacher and student. I really was
having fun with this one and I got to see the graph being made as the ball was

4. The ease of using the materials (Will first time users find it easy to use
the software?)

It was quite easy to use until my computer locked up at this site.

It really is a fun site.

I spent about 5min browsing. This site is a great tool if you are more of a
visual learner like myself. The content is great especially the animation where
you can actually see how the ball bounces. It seems to be pretty easy to use,
but I was wondering if you can customize the models in accordance with a real
world setting? it would be intersting to see how a ball bounces within the
context of sports like basketball, baseball,ect.

As a math student I found this program to be very interesting, especially
becasue I remember being frustrated by "ball bouncing" problems in my calculus
classes. This program Really gives you a realistic real world view of the
physics of the bouncing ball.

Technical Remarks:

I Found the controls at the bottom of the screen hard to understand and use.
Can you speed up the ball? I didn't understand how to manipulate the motion of
the ball. A good addition to this program would be a way to add in your own ball
bouncing equation so you could actually try the problems given as homework

I spend 5 min exploring the material of this site and I thought that it was a
very good site to go to for children in the 3ed or 4th grade it was very easy to
understand how the ball bounces over the per of time and distance it was easy
to teach and learn from the marital I thought that the site hade a lovely
graphic in it took it one step at a time by showing just with the ball at first
and then with the graph lines
