**Other Considerations**

• There should be an emphasis on the understanding of the underlying concepts.

• Communication, both oral and written, should be emphasized throughout the

course. Written solutions to problems should be expected and evaluated.

• Students should be allowed to use graphing calculators and computers where

appropriate.

• There should be an emphasis on functions as mathematical models.

• At the end of each semester, a summary of the mathematics covered should occur

in which the relationships among concepts are emphasized.
