Highlighting and illustrating several important and interesting theoretical trends that have emerged in the continuing development of instructional technology, this book's organizational framework is based on the notion of two opposing camps. One evolves out of the intelligent tutoring movement, which employs artificial-intelligence technologies in the service of student modeling and precision diagnosis, and the other emerges from a constructivist/developmental perspective that promotes exploration and social interaction, but tends to reject the methods and goals of the student modelers....

Since the NeuroTouch simulator platform is being utilized throughout the word by multiple centres to foster neurosurgical technical skill acquisition, it is critical to study the validity of this system. In this work, we assessed the psychomotor skills of board certified neurosurgeons (experts), senior and junior neurosurgical residents, and medical students while performing a variety of simulated brain tumor resections. Motor skills of operators are measured objectively using a set of novel performance metrics derived from the simulator. The authors provide a statistical analysis of each...
