WHEN IS A SCHOOL ENVIRONMENT PERCEIVED AS SUPPORTIVE BY BEGINNING MATHEMATICS TEACHERS? EFFECTS OF LEADERSHIP, TRUST, AUTONOMY AND APPRAISAL ON TEACHING QUALITY

This study examines the hypothesis that the more support beginning mathematics teachers perceive and the better they evaluate the management of their school, the higher their teaching quality is. Indicators of teaching quality were how the teachers, who were in their third year in the profession, regarded themselves able to cope with the challenges of mathematics instruction and generic tasks like classroom management and how satisfied they were with their job. Indicators of support were the level of appraisal and autonomy the teachers reported. School management indicators were the administrative leadership of the principal and the climate of trust as perceived by the teachers. Our results reveal that teacher support plays an important role in the quality of beginning mathematics teachers. All quality indicators improved significantly if beginning teachers reported more appraisal and autonomy. A climate of trust plays an important role for the extent of autonomy perceived. Administrative leadership was significantly related to the amount of appraisal the teachers reported. Our results provide important information on how to steer a school so that the quality of beginning mathematics teachers is maximized.     

An overhead reduction technique for mega-state compression schemes

Many of the most effective compression methods involve complicated models. Unfortunately, as model complexity increases, so does the cost of storing the model itself. This paper examines a method to reduce the amount of storage needed to represent a Markov model with an extended alphabet, by applying a clustering scheme that brings together similar states. Experiments run on a variety of large natural language texts show that much of the overhead of storing the model can be saved at the cost of a very small loss of compression efficiency.     

德国大学的制度结构

本文以组织进化理论的眼光审视了德国大学近三百年的发展历程,从中抽象出德国大学作为一种制度的基本规则,并运用横向与纵向的比较和梳理勾勒出德国大学历史发展背后的脉络.本文指出,德国大学的制度核心,即对德国大学系统构成起到基础性作用的制度规则主要是:国家与大学紧密联系,却又不损害大学本身的学术自由;德国大学在知识上具有极大的包容性,并倡导研究与教学相统一;最后,在德国分权化的政治背景下,大学之间的自由竞争推动了德国高等教育的发展.     

Changing leadership: Teachers lead the way for schools that learn

This paper presents findings from a three-year, qualitative study of teachers enrolled in a Masters of Teacher Leadership program. Researchers sought to understand the ways teachers’ beliefs about and understandings of teacher leadership were affected by their participation in a formal teacher leadership program, as well as the kinds of actions they took up as a result of this participation. Data indicate three significant ways participants’ work as teacher leaders was developed and enhanced, including: (a) identifying and amplifying their professional voice, (b) deepening and extending their voice as they plan, and (c) reframing their work/shift responsibility through constructing widening circles of influence and impact. Authors identify implications of their research for growing teacher leaders, school improvement and change, changing school culture, enhancing student engagement, and building new structures.     

Tocqueville in Cyberspace: Using the Internet for Citizen Associations

Political theorists like Alexis de Tocqueville have long recognized the importance of citizen associations for the practice of democracy. Through participation in associations, citizens both receive an education in public affairs and create centers of political power independent of the state. Essential to participation in an association is participation in a forum, a communication space that allows for many-to-many communication in which citizens can "treat of public affairs in public" (Tocqueville, 1945, p. 109). Participation in forums suffers from numerous barriers, however, such as the need to meet in one common place, the need to meet at one common time, and the potentially high costs of participation. Online forums on the Internet avoid many of these barriers, and thus they hold the promise of facilitating the formation and operation of citizen associations. This was confirmed in 1995 by the experiences of a Boston-based citizen association, the Telecommunication Policy Roundtable-Northeast (TPR-NE). TPR-NE's uses of the Internet suggest that online forums may allow associations to be more responsive, more robust, and able to unite more members.
