One of the most exciting and important features of the Science Alive CD-ROMs is the inclusion of special icons that link to learning objects, checkpoints and chapter tests.

Learning objects use text, still or moving graphics, video, audio or any combination of these media to present information to the student on specific topics. Each learning object links to an associated eTivity. An eTivity tests the knowledge presented in the learning object. The eTivity links back to the learning object to allow the information to be reviewed if necessary.

The checkpoints in the Science Alive CD-ROMs provide an index to all learning objects in the chapter to that point. They also link to five quick questions — a mini-test of the content covered so far.

Chapter tests contain ten multiple-choice questions that are randomly generated from a larger pool of questions — so you can do these tests over and over with minimal chance of doing exactly the same test more than once.
