Air-sea Interactions: Activities in Oceanography
Steve LaDochy, California State University, Los Angeles
This online set of activities help students learn properties of ocean waves, wind-wave relationships and properties of tsunamis.

Three-Point Problem by Simultaneous Linear Equations
William Frangos, James Madison University
Students are introduced to the use of linear algebra in an intuitive and accessible way, through classroom activity and homework set. The familiar three-point problem is cast in terms of three dimensional analytic geometry, fostering understanding of mathematical models for simple geometric forms.
