Susan Hert,Sanjay Tiwari,Vladimir Lumelskyhas provided powerful tools for mathematics education research. This chapter briefly considers Piaget’s background in biology and his interest in mathematics that together help account for why his work has been particularly useful in researching children’s mathematical thinking and learning.

Case-Based Path Planning for Autonomous Underwater Vehicles,around reuse of old routes, it would be fast especially when long routes need to be generated. Moreover, better reliability of paths can be expected as they are adapted from earlier missions. The scheme is novel and appropriate for AUV mission scenarios.
