How I reviewed the material: The site is quite compact, so I just tried it out
and read the instructions.

My evaluation of content quality: I was excited about having a virtual abacus,
but I was disappointed in the extremely limited ideas about how to use an abacus
and how to really use the simulation.


My evaluation of effectiveness for teaching or learning: I think that a real
life abacus would suit the bill better. Not sure where to get them?maybe in SF
Chinatown? Can always make them. And then get an age appropriate manual for
it.

This might be useful as a curiosity answerer. Can send student to this site to
at least get a feel of an abacus.

My evaluation concerning ease of use The program was not very responsive.
Clicking on beads might not create movement for more than 3 or 4 seconds.

1. 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 15-20 minutes reviewing this material.

2. The quality of content (Does the materials accurately present concepts and
models that are educationally significant?)
The quality of the content was good because the author presented how an abacus
works in a simple and easy to understand way. It is educationally significant
because the abacus was essentially the ?first calculator?. Although the abacus
is no longer a practical tool now that we have electronic calculators, it is
still interesting to know how an abacus works from a historical perspective.

3. The potential effectiveness for enhancing teaching and learning (If used
appropriately, will students' learning and faculty's teaching be enhanced?)
If used appropriately students learning could certainly be enhanced. Although
the lesson on how the abacus works was not particularly long, it was clear and
easy to understand.

Technical Remarks:

4. The ease of using the materials (Will first time users find it easy to use
the software?)
The website was fairly easy to use. The information was well organized, and
although sometimes the material was slightly confusing at times, I mostly
understood the author?s explanations of how the abacus works. I also liked that
he included a graphic where you could move the abacus beads up and down.

I spent about an hour reading and playing with the abacus. After reading
the tutorial, I continued to make many attempts at creating and solving a
multitude of simple arithmetic problems. Now I know how to use an abacus!!! The
tutorial is written in a very simple and clear manner with step by step
explanations. In learning any hands-on tool, simplicity in explanation is
essential. This format is a very strong example of how arithmetics can be taught
to those students whom are kinesthetic and visual learners. The abacus is an
ancient yet very applicable tool for todays learning environments.

Technical Remarks:

It would make the arithmetic explanations stronger if there were an abacus
available right next to the explanation, in comparison to reading the
explanation then scrolling back up to try it. I know it takes a lot of time to
create that ability, but it would make the tutorial all the more stronger.
Overall, it was great and very informative.

I approximately spent about 35 minutes on this site. It was fascinating for me
because I have never actually interacted with an Abacus before. As an addition
and subtraction tool, I can see the effectiveness and utility that could come
out of an Abacus for a young student. Also, the Chinese characters that were
includeded in the site were an incentive for me because, once again, I have
never been subjected to them. This site could most definitely be an accessory
and a teaching aid for an instructor.

Technical Remarks:

I had no technical difficulties with this site. In addition, it was a pleasure
interacting with the virtual Abacus.

Very simple and informative site regarding the Abacus. I have never actually
used an Abacus so I found the site to be interesting. The general explanations
and intructions on how to add/subtract using the Abacus were good. I spent
about 20 minutes reading the site and trying the Abacus. As far as a teaching
tool, if for some reason I needed to explain how to use the abacus or give a
demonstration of what an Abacus is I would definitely reference this site
because it is brief and concise. I think that anyone could learn using this
site.

Technical Remarks:

My computer did not have Java Virtual Machine installed so I had to download it
and install it prior to viewing the online abacus.

I enjoyed reading about the abacus. I knew that the abacus was created as a
counting mechanism centuries ago but never understood how it was used. This
report could use some more diagrams as Luis explains how to add and subtract,
especially give examples of moving the beads from one rod to another. The
content is understandable. I spent about 10 minutes reviewing the material.
Again, with more diagrams this could be a very effective teaching tool in
showing children the history "grassroots" of mathematics and in teaching them
how to count.

Technical Remarks:

I had no technical difficulties.
