Supplemental instruction classes have been shown in many studies to enhance performance in the supported courses and even to improve graduation rates. Generally, there has been little evidence of a differential impact on students from different ethnic/racial backgrounds. At San Francisco State University, however, supplemental instruction in the Introductory Biology I class is associated with even more dramatic gains among students from underrepresented minority populations than the gains found among their peers. These gains do not seem to be the product of better students availing themselves of supplemental instruction or other outside factors. The Introductory Biology I class consists of a team-taught lecture component, taught in a large lecture classroom, and a laboratory component where students participate in smaller lab sections. Students are expected to master an understanding of basic concepts, content, and vocabulary in biology as well as gain laboratory investigation skills and experience applying scientific methodology. In this context, supplemental instruction classes are cooperative learning environments where students participate in learning activities that complement the course material, focusing on student misconceptions and difficulties, construction of a scaffolded knowledge base, applications involving problem solving, and articulation of constructs with peers. 相似文献

For this study, information on Who Bullies Who was collected from 54 school classes with 918 children (M age = 11) and 13,606 dyadic relations. Bullying and victimization were viewed separately from the point of view of the bully and the victim. The two perspectives were highly complementary. The probability of a bully-victim relationship was higher if the bully was more dominant than the victim, and if the victim was more vulnerable than the bully and more rejected by the class. In a bully-victim dyad, boys were more often the bullies. There was no finding of sex effect for victimization. Liking reduced and disliking increased the probability of a bully-victim relationship. 相似文献

This study demonstrates how academicians and practitioners can work together on an important topic that matters to organizational performance: the pivotal role played by salespeople during new product launches. In particular, the authors present three potential interventions that training and sales managers may use to sell a new product to salespeople. The results legitimatize the critical contribution of sales training to new product sales performance and highlight the value of the partnership between training professionals and sales managers. 相似文献

Many organizations have adopted a wide variety of approaches in introducing selected practices for achieving control of the quality of their products and services. Some of these piecemeal applications of the Quality Sciences have been successful–to varying degrees and for a time. However, the only approach that achieves long-term success is that requiring a complete cultural change in most organizations– involving a refocusing of all activities performed by everyone toward mutually intersupportive efforts to reach a common objective. In a word, a Quality System is required. In this paper, I have attempted to portray the basic considerations involved in developing and installing such a system. This is accomplished by describing some of the background of the system concept, certain of the internal and external features of a Quality System, and, to complete the picture, a semi-fictitious recital of the experiences of a company that has decided to embark on the Quality System journey. 相似文献
