《论语》的历史人物评价视角小议

儒家经典《论语》涉及的内容相当广泛,其哲学、政治、教育等内容人们常有提及,而对其历史人物的评价这一方面,目前所论尚不多见。本文即从其对历史人物的评价视角这一层面进行探讨。按其对历史人物的评价的性质和内容,可分为仁德视角评价、功用视角评价、礼法视角评价、任贤视角评价和情趣视角评价五种类型。

Stichwort: Bildungsökonomie und Qualität der Schulbildung

Keyword: Education Economics and Quality of Schooling. With reference to an earlier keyword article from the same author, this contribution looks at recent developments in education economics. The focus is a critical review of the field‘s contribution to research on the necessary conditions for high quality schooling. Of particular interest at the moment are the institutional framework conditions in a school system, which set incentives for performance. These are judged to be better than resource-based strategies of quality assurance. The empirical basis is provided by estimates of production functions using data from international school performance studies. This article will point out the limited validity of evidence gained through these studies and the – in sum – contradictory empirical findings. For this reason, political recommendations on the basis of this approach should be more reserved.     

Empirical evidence of the impact of lesson study on students’ achievement,teachers’ professional learning and on institutional and system evolution

In this article we review the evidence of the impact of lesson study on student learning, teacher development, teaching materials, curriculum, professional learning and system enhancement. We argue for lesson study to be treated holistically as a vehicle for development and improvement at classroom, school and system levels rather than as a curricular or pedagogical intervention. We illustrate the need for this approach to evaluating lesson study through a complex case exemplar which used Research Lesson Study (a form of lesson study popular in the UK and Europe) to develop learning, teaching, curriculum and local improvement capacity across schools initially involved in a two‐year mathematics curriculum development project that later evolved into three self‐sustaining, voluntary lesson study school hubs in London. We discuss resulting changes in culture, practice, belief, expectation and student learning. We argue as a result for greater policy level understanding of this expanded conception of lesson study as a vehicle in classroom, school and system transformation.     

Construction of meaning in the authentic science writing of deaf students

This study examines how students construct meaning through writing during authentic science activities. To determine how well students understood science concepts, we analyzed 228 writing samples from deaf students in grades 6 through 11 as well as the explanatory and reflective comments of their teachers. The analyses indicate that certain process writing strategies were differentially useful in helping deaf students to construct meaning and in allowing teachers to evaluate the constructed meaning. Three instructional conditions and two teacher variables were found to play roles in determining the accuracy and adequacy of the writing: (1) the writing prompts the teachers used, (2) the focus for the writing, (3) follow-up to the initial writing activity, (4) the teacher's content knowledge, and (5) the teacher's ability to interpret student writing. The authors recommend future applications of writing-to-learn strategies and suggest directions for further research and changes in teacher education.

试论高校内部和谐权力话语关系的构建——基于对J省高校的调查研究

文章通过对J省高校内部权力运行情况调查,比照当下教育语境阐释高校内部三种权力话语:一是以行政管理人员为主的行政权力话语;二是以教学科研人员为主的学术权力话语;三是以学生为主的学生权力话语。三种权力话语的阐释,意在以权力话语理论为指导,突破以往的认知限制,促进三种权力话语的有效对话,以三权相互独立又相互制衡的大学治理理念,构建大学组织的和谐权力配置模式。

The Relationship Between Academic Major and Environmentalism Among College Students: Is it Mediated by the Effects of Gender,Political Ideology and Financial Security?

Several studies have found a relationship between college students’ academic majors and their environmental attitudes and behaviors. Results from this study of incoming first-year students at a medium-sized public university suggest that students majoring in different programs of study were likely to have different environmental attitudes and behaviors. There were also differences in the proportions of women, political liberals, and financially secure students in each of the different majors. When controlling for the effects of gender, political ideology, and financial security, incoming business majors scored lower on two of the four measures of environmentalism than incoming students in the other majors. The findings in this study suggest that incoming students choose majors that are consistent with their worldviews.
