It is suggested that students collect interarrival data for customers arriving at a queue. Two common features will often occur across these various datasets. Some data collection hints, some problems for students to pursue and a few pointers to the literature are given. 相似文献

Attention to significant commonalities between the position of teachers and police officers, we suggest, illuminates problematic aspects of their position within a democracy. Demographically, both the teaching force and the police force are disproportionately white, yet the commonalities extend beyond race. We suspect too little attention has been paid to other social categorizations, namely social class and gender. Toward this end, we explore the significant commonalities between the position of teachers and police officers and suggest that aspects of their position within a democracy make accountability a problematic tactic for addressing systematic failures. In this article we turn to Plato's discussion of the guardians for his ideal Republic because Plato squarely faces a problem that still dogs us: How are those persons given the right to uphold order to be prevented from turning on the polis they are meant to protect? The answer we offer rests on a theorization of a middle position and on a democratically situated ethical response to the other. 相似文献

The effects of two types of structured academic conflict, controversy and debate, were compared with individual study in a study on desegregation. Seventy-two sixth grade students were assigned to conditions on a stratified random basis controlling for sex, reading ability, and ethnic membership. In all three conditions students studied a controversial issue with materials representing both pro and con views. In the controversy condition each learning group was divided into two pairs representing the pro and con sides. In the debate condition each member of a learning group was assigned a pro or con position to represent in a debate with the other three members. In the individualistic condition subjects were told to learn the material without interacting with other students and each student was given all the pro and con materials. The results indicate that controversy promotes the most cross-ethnic verbal rehearsal and exchange of the assigned material, the most concern that all students master the assigned material, the most active search for more information about the topic being studied, the most reevaluation of one's position and incorporation of opponents' arguments, the most liking for the subject matter and the instructional experience, the highest self-esteem, and the most accepting and supportive relationships among minority and majority students. The debate condition generated higher levels of these dependent variables than did individualistic study. 相似文献
