Removed links to under construction pages. Previously when
you clicked on a teacher or activities menu item, an "Under Construction" page
would be displayed. This resulted in people giving up on trying the links. Now,
menu items only appear when they link to content.
Modified design so activities or instructions open automatically.
Feedback indicated that some people were unsure of how to use the applets and
wished that information was displayed immediately so they did not have to go
looking for it. Based on that feedback, the design was modified so that some
manipulatives open up with the instructions or an activity displaying immediately.
Added linking options. You may now create links to manipulative
pages that also display the instructions, teacher, or activities page. In a Windows
browser the base URL for a manipulative is displayed in the address window at the
top of the virtual manipulative page. In a Macintosh web browser the base URL for
a manipulative can be seen by choosing Page Info from the View menu. The base URL
is everything before the question mark character. You may create links that open
the instructions, teacher or activities page by using syntax in the table that
follows. The examples shown must be preceded by http://matti.usu.edu/nlvm/nav/.
Fixed browser-specific bugs. The NLVM website previously was not viewable in browsers running Mac OS X. It now is.
