The present research investigated whether immediate metacognitive feedback on students’ help-seeking errors can help students acquire better help-seeking skills. The Help Tutor, an intelligent tutor agent for help seeking, was integrated into a commercial tutoring system for geometry, the Geometry Cognitive Tutor. Study 1, with 58 students, found that the real-time assessment of students’ help-...

Any designer of intelligent agents in a multiagent system is faced with the choice of encoding a strat egy of interaction with other agents If the nature of other agents are known in advance a suitable strategy may be chosen from the continuum be tween completely sel sh behavior on one extreme and a philanthropic behavior on the other In an open and dynamic system however it is unrealis tic to ...

Any designer of intelligent agents in a multiagent system is faced with the choice of encoding a strategy of interaction with other agents. If the nature of other agents are known in advance, a suitable strategy may be chosen from the continuum between completely sellsh behavior on one extreme and a philanthropic behavior on the other. In an open and dynamic system, however, it is unrealis-tic ...

Consider a sequence of i.i.d. random variables, where each variable is refreshed (i.e., replaced by an independent variable with the same law) independently, according to a Poisson clock. At any xed time t, the resulting sequence has the same law as at time 0, but there can be exceptional random times at which certain almost sure properties of the time 0 sequence are violated. We prove that the...
