Details are given of a method used by a student in discovering the relationships between the area under the sine curve and the unit circle. Two computer programs for the required calculations are included. (DT)

Discusses how to teach literature so that the student will most successfully retain and assimilate the information developed in the work. (RB)

Flexibility in the application of instructional methods is the best approach to a teaching situation. Insofar as possible, a combination of traditional learning methods with heuristic (problem solving) and programed ones should be used. (CK)

There were no significant differences in achievement between students using an earth science laboratory block with or without teacher direction. (AL)

The three teaching methods are not only compared, but predictors for matching students with techniques are investigated. (DG)

An approach is presented that is based on modifying the standard axiomatic system found in high school geometry books. Such changes start with the introduction of a side-angle-side (SAS) postulate for similar triangles. It is shown how the new system can prove existence and uniqueness of parallel lines. (MP)

An approach to how to expand explorations of determinants is detailed that allows evaluation of the fourth order. The method is built from a close examination of the product terms found in the expansions of second- and third-order determinants. Students are provided with an experience in basic mathematical investigation. (MP)
