RandomSelector is a tool for classroom selection and
experimentation. Using this tool educators and students can make
random selections from sets stored as text files. For example,
RandomSelector can call on students randomly, or simulate flipping
coins or drawing socks from a drawer.
Random selector is very easy to use! It has been designed that way
from the beginning.
Note that at this time all selections are made with replacement;
i.e., the list we are selecting from does not shrink as selections are
Example: Selecting a name
In this example we see a name selected
from a alist of names in the file and dynamically displayed with a
pause between characters. Not only is the name randomly selected, but
the characters in the intermediate frames are randomly chosen as well.
Example: Flipping a coin and drawing socks from a drawer
In this example we see a coin
flipped, a sock drawn from one of two drawers, and a simultaneous coin
flip and sock drawing.
You can open several files in RandomSelector and it will merge them
into one list from which it makes a selection. You can open the same
file more than once to give it more weight in the selection process.
RandomSelector provides numerous display options. Below is a
screenshot of the Options dialog.
