Native Apps

Executables (64-bit and 32-bit) for Windows and (64-bit) for Macintosh computers are available for all of our older projects (NAAP, ClassAction, & Ranking Tasks). The appropriate package for your (or your student's) computer system must be downloaded and installed locally. Note that these are actual applications that run in your native OS and their longevity depends only upon your OS. There is no similar viable solution for Chromebooks.

Note that every simulation available in the past on this site is contained in either the ClassAction or NAAP Labs native app. (In ClassAction look under the Animations tab.) The following guide to content is provided to assist you in navigating. Student guides and demonstration guides can be found on the NAAP Resources page.

Information on Running a Native App from a Thumbdrive

For Windows

It is possible to run a Native App off of a thumbdrive (USB flashdrive). This procedure has NOT been widely tested.
