2 Sarah Leach, Department of Mechanical Engineering Technology, Purdue University, South Bend, Indiana, [email protected] Abstract ? This paper describes the development and use of several interactive 3-D models for use in Fluid Power, Fluid Mechanics, and Machine Design courses. Instruction in these subjects often involves interpreting static 2D representations of complex mechanisms and fl...

Constructing models of dynamic systems is an important skill in both mathematics and science instruction. However, it has proved difficult to teach. Dragoon is an intelligent tutoring system intended to quickly and effectively teach this important skill. This paper describes Dragoon and an evaluation of it. The evaluation randomly assigned students in a university class to either Dragoon or bas...

We documen t extreme bias and dispersion in the small-sample d is t r ibut ions of four s tandard regression-based tests of the expectat ions hypothesis of the term structure of interest rates. The biases arise because of the extreme persistence in shor t interest rates. We derive approx imate analyt ic expressions for the biases under a simple f irst-order autoregressive da ta generat ing proc...
