Seeking conceptual clarity in the action modalities

This article begins with the presumption that action learning has not made as deep an impact in promoting participatory social change as its supporters may have hoped for, but nor has its cousin action modalities, such as action research and action science. These action strategies have evolved separately along distinct traditions and, rather than focus on their commonalities, their proponents have tended to cite their differences from one another. As a result, they have seldom stood together to advocate for their shared epistemology based on practice as the fundamental unit of analysis. Accordingly, after briefly summarizing the history and differences among these action modalities, this article will focus on their potential confederation. It cites ten unifying elements that may construct an agenda characterized by the value of learners collectively reflecting on planned engagements that can not only expand but can create knowledge while at the same time serving to improve practice.     

印前数字图像清晰度评测方法

数字图像的质量直接决定着印刷品的质量,数字图像的清晰度是判断数字图像质量的重要指标。建立印前数字图像清晰度评价标准对于印刷业有着广泛的意义。印前数字图像清晰度可以从有参考和无参考两个方面进行评测。有参考评测主要根据印刷图像所需要的分辨率要求确定当前图像是否符合印刷要求。无参考评测可以利用基于焦点窗口的清晰度评价方法,检测出图像的不同区域清晰度,并以此作为印刷图像清晰度的参考值。以上两种方法在实际应用中都取得了良好的效果。     

教师教育与教师专业化

积极推进教师专业化 ,使教师职业像医生、律师一样专业具有不可替代性 ,应该成为“十五”教师教育的热点与主旋律。这就要求教师的培训机构、教师管理保障制度、教师教育培训制度 ,都实现相应的重大变革。这是师范教育及教师培训机构必须面对的重要问题     

未曾谋面的老师"网络教师"在2005

教师这种古老的职业,今天有了全新的面孔 信息技术手段的广泛应用,正在改变"教师"的职业面孔.那个鲜活的、具体的、或高大严厉或斯文和蔼的形象,似乎正在从传统的课堂上隐去;而留下的,不仅仅是电脑屏幕上的光点所闪烁出的智慧之火,还有在这屏幕背后,教师这个群体所面临的或重大或细微的职业变化.     

教师文化与教师专业成长

教师文化的类型与教师的专业化程度存在着密切的内在联系。二者在教师职业发展历程中相互促进、相互制约共同发展着。其关系在动态上表现为适应中的共同发展,在静态上表现为制约中的相互促进。专业化的教师文化的形成需要在教师职业专业化的实践进程中,由全社会配合教师群体共同加以培育、生成。     

教师借调与教师专业发展

本文介绍"借调教师"的概念,旨在为教师专业发展提供一种新取向,以强化当前教师专业发展的模式.本文以教师借调到香港一个"大学-学校"伙伴协作学校改进计划的经验为例,以实证研究方法探讨教师借调期间的经历对其个人专业发展及成长的影响,进而分析以此作为教师专业发展模式的意义.所提出的"教师借调"概念可弥补传统教师培训模式的一些局限.     

教师专业化与教师教育模式研究

一个国家的发展必须要有大量的高素质人才做支撑,人才的培养在教育,教育的关键在教师。教师专业化无疑是提高教师素质的最佳途径,教师专业化已成为当今世界教师教育发展的趋势。在论述教师专业化的基础上,着重研究了加快教师的专业化过程中的几种教师教育模式:“能力本位”模式与“标准本位”模式、良师辅导模式、校本培训模式、教师专业发展学校模式、“相似教育模式”。并对教师教育模式的选择提出了一些看法。     

教学语言与英语教学语言

在英语教学活动中 ,教学语言与英语教学用语在概念上不仅不同于普遍的交际性语言 ,而且它们在结构与使用上又都有着自己的特点和规律。本文试对两者之间的关系加以探讨 ,并侧重探讨英语教学语言的特点及使用。     

Teacher Time Utilization with Teacher Aides

Abstract

This study explored the relationship between cooperative and competitive instructional environments in which high level teacher questions were the primary instructional strategy and student achievement was measured by recall of content and the ability to respond to high level test questions. Ninety-six fifth grade students were randomly assigned to one of three groups: competitive environment (Cm), cooperative environment (Co), and control (C). Results of the data analysis by MANOVA indicated that Cm and Co did better than C on both low level and high level portions of the posttest. There were no significant differences between Cm and Co in low level understanding, but significant differences in favor of Cm over Co did emerge on the high level subtest. The implications for structuring classroom environments and the need for further research studies are discussed.     

State Teacher Evaluation and Teacher Education

Contemporary test-based reforms are often grounded in the claim that test performance is the key to international economic competitiveness. However, this oft-repeated assertion lacks empirical support. According to the World Economic Forum, the United States' recent loss of economic competitiveness standing is due to macroeconomic instability rather than to a lack of workforce skills and knowledge. In contrast to the claims of President Obama and Secretary Duncan, the nation has no shortage of qualified job applicants. There are, on average, three qualified applicants for every high tech job. Furthermore, 80% of projected jobs require only technical or on-the-job training. The vast majority do not require the skills measured by contemporary accountability schemes. For example, only 5% require any math beyond basic operations. Educators must continue to focus on equality of educational opportunities for all children and, as contrasted with narrow economic rationales, embrace a broader vision of the purposes of education.     

老师

我是一粒幼小的种子, 你使我成为美丽的花朵; 我是一颗新星, 你使我成为耀眼的太阳; 我是一块普通的石头, 你使我成为一粒闪亮的宝石;     

Performance appraisal format: Role clarity and evaluation criteria

The effectiveness of alternative performance appraisal formats is evaluated in terms of their contribution to selected dimensions of role clarity, and their focusing the evaluation on primary criteria as opposed to secondary criteria. The formats studied are: simple graphic rating scales, more complete graphic rating scales, and behaviorally anchored rating scales. From the viewpoint of the person being rated, the dimensions of role clarity investigated are: understanding of the performance dimension being rated, understanding of where the faculty member stands on each performance dimension, and understanding of the behavioral changes that would improve ratings on each performance dimension. Behaviorally anchored rating scales are observed to be superior to the other rating scale formats on each dimension of evaluation.     

Teacher as Researcher,Teacher as Scholar,and Teacher as Leader

ABSTRACT

Too often, because of the static nature of schools and the dominant existence of high-stakes testing, professional learning for teachers is determined by administrators or policy and is facilitated by those who are not part of the school community using prepackaged programs. These initiatives run counter to authentic teacher inquiry where teachers enhance their understanding of students and learning and, ideally, develop new teaching practices (Borko, 2004; Cochran-Smith & Lytle, 1999, 2009; Darling-Hammond, 1997). In this article, we focus on how teachers participating in action research begin to position themselves as teacher leaders.
