Online simulation - why use it?

I have used the website http://frog.edschool.virginia.edu/Frog1/ to review its purpose.

The purpose of the site is to show people how to practice dissecting a frog and can also give brief demonstrations via a multimedia download which is played using QuickTime. The student is also allowed to practice what they have learned on a picture of the frog but I have found this to be very unresponsive in certain areas of the picture e.g. the practice information told me to click on where I believed the frog should be pined I was able to click on top limbs which were at the top but the bottom limbs always came up with “this is incorrect” making the practice frustrating.

The site is very good on helping students understand what they have to do before dissecting a frog but the site is highly unusable for dissecting a frog as it is pictures taken and u the student is asked to click on areas that are unresponsive making the student learn nothing as the dissection would not work also because there is no animation the student does not know whether they have dissected any part of the frog as it only says “you are correct” or “you are incorrect”.

What this site shows me about online simulation for education is that it needs more work as the site is unresponsive in allowing students to proceed and as there is no animation nothing can be shown as the student progresses so dissecting a real from is the better way at the moment.
