Learning science through dialogic inquiry: Is it beneficial for English-as-additional-language students?

While the effectiveness of teaching that emphasizes dialogue and inquiry has been well documented with respect to English-as-mother-tongue children, it remains an empirical question as to whether this approach is equally useful when the student body includes a substantial number of English-as-additional-language (EAL) students. Through a longitudinal study of one class in an elementary school in California, we address this question in the context of a science unit that evolved over 4 years in response to the dramatic increase of EAL students in the school. Both the quantitative and qualitative analyses carried out on the data strongly suggest that dialogic inquiry can be effective for EAL students as well as for their mainstream peers when the teacher also systematically and strategically integrates literacy with science instruction and strikes a balance between hands-on and text-mediated investigations.     

Critics’ and public perceptions of violence in television programs

The following article is one of the first fruits of a million dollars’ worth of research by some two dozen investigators that was sponsored by the Surgeon General's Scientific Advisory Committee in an attempt to examine the possible links between the mass media and violence. The research upon which this particular publication is based was performed pursuant to Contract No. HSM 42–70–32 with the National Institute of Mental Health, Health Services and Mental Health Administration, U.S. Department of Health, Education and Welfare. Dr Greenberg, associate professor in the Department of Communication at Michigan State University, and a frequent contributor to the Journal, was the principal investigator. Mr. Gordon, a Ph.D. candidate, was senior research assistant in the same department.     

Tattoo Torment

刺青是一项古老的传统，至今已有两千多年的历史。古时候，人们多用它来表明身份；现如今，它则成了张扬个性的一种手法。不过，在做刺青前一定要有充分的心理准备，如果哪天后悔了，想去掉都难!     

基于标准的评核：教育领域人力资本和能力提升的工具与方法

本文概述了一种评核概念和理论，即基于标准的评核。这种评核模式通过把学生的成绩和他们的知识、课程标准联系起来，给学生的学习成绩赋予意义。它有效地将评核的焦点从对成绩排名的关注（仅仅把学生的表现与同学相比较）转移到了对学生学习进步的关注上来。本文关注这一转变过程，并为这一评核方式的实施提供可能的策略。同时，本文认为这一评核体系将会对教育中人力资本和能力提升产生深远的影响。
