基于上下文语义的网络议程设置研究——以红黄蓝事件为例

基于共现分析的网络议程设置研究从认知心理学的角度出发,分析媒体议程与公众议程网络,更加贴近回答李普曼所说的“我们脑海中的图景”,但该方法只能体现议程网络中关键词间的显性关系。本文提出通过基于上下文语义的word2vec模型,测度网络议程设置中关键词隐性关系的研究方法。以“红黄蓝事件”为例,揭示党媒、都市类媒体、商业媒体、知乎意见领袖以及公众的议程网络及其相似度。研究发现,知乎意见领袖对公众议程的影响程度最大,其议程主要是对事件背后因果关系的梳理以及对策建议的提供。在媒体方面,党媒和都市类媒体报道基本一致,且二者对公众的影响均高于商业媒体。本研究是对现有网络议程设置研究的补充,对议程设置的本土化研究有一定的启示。

Randomizing multiple contingency components to decrease disruptive behaviors and increase student engagement in an urban second‐grade classroom

Disruptive behaviors displayed in the classroom interfere with learning by taking time away from academic instruction. This study investigated the effects of randomizing components within an interdependent group contingency for group disruptive behavior and engagement levels of 26 students in a second‐grade classroom in an urban Midwestern school. Using a multiple‐baseline‐across‐settings design, baseline levels of group disruptive behavior and engagement were compared to intervention levels across three different class periods. Results suggest that the intervention decreased levels of disruptive behavior and increased levels of student engagement. Benefits of randomizing components within an interdependent group contingency are discussed as well as limitations to this study and suggested areas of future research. © 2010 Wiley Periodicals, Inc.

Research Supervision: An Important Site of Teaching

Supervision of students engaged in research projects and theses is an important site of teaching. Schon's (1987) well-known framework–educating for reflective practice–proves aptly suited for this teaching forum, offering insights for research supervision at multiple university levels. Conceptually, a research and writing studio where a practicum takes place is substituted for Schon's illustrative architectural design studio. The framework is mined for its fine-grained analysis of student-coach interaction and its emphasis on bringing self-reflection, a practice consistent with social work ideals, to three levels: research and writing, the student-coach dialogue and the relationship in which it is embedded.     

U.S. Virtual School Trial Period and Course Completion Policy Study

Abstract

Variation in policies virtual schools use to calculate course completion and retention rates impacts the comparability of these quality metrics. This study surveyed 159 U.S. virtual schools examining the variability in trial period and course completion policies—two policies that affect course completion rates. Of the 86 respondents, almost 70% had trial periods that varied from 1 day to 185 days. Course completion definitions varied from remaining in the course irrespective of the final grade to receiving an A– in the course. Such wide variation renders the completion and retention rate metrics useless. We recommend virtual schools adopt consistent measures for calculating student retention to allow meaningful comparisons among virtual schools and between virtual and brick-and-mortar schools.
