Separated and integrated perspectives on environmental,economic, and social dimensions – an investigation of student views on sustainable development

The sustainable development (SD) concept is based on the idea that economic and social development should be linked to the environment. However, controversies about various associated issues often arise due to the differences in protagonists’ viewpoints, depending partly on whether they focus mainly on environmental, economic, or social dimensions and partly on ideological stances related (for instance) to the optimal ways of promoting economic growth and social justice. This study investigates views of 638 Swedish upper secondary students who responded to a questionnaire probing their views of SD from two perspectives. In the first, the dimensions were separately introduced, so the respondents only had to consider one dimension at a time. In the second, the dimensions were introduced in an integrated fashion, so the respondents had to consider effects related to all three dimensions. The results strongly indicate that the students’ views and priorities concerning the dimensions depend on both the perspective and the context. Implications for teaching and learning are discussed.     

教育管理决策的适应思维范式

科学认识和价值认识发展轨迹的融合产生了当代教育管理决策的适应思维范式。在这种思维范式下 ,我们应该主动把握教育决策事件发展的统计因果关系 ;充分考虑到教育决策事件的经济价值、社会政治价值、科学价值、审美价值。在决策主体、决策方法和决策对象上应把握适度分权、非线性和自主性等全新特征。惟有如此 ,才能适应当前教育环境和教育教学改革需要     

Emerging Educational Institutional Decision-Making Matrix

The ＂emerging educational institutional decision-making matrix＂ is developed to allow educational institutions to adopt a rigorous and consistent methodology of determining which of the myriad of emerging educational technologies will be the most compelling for the institution, particularly ensuring that it is the educational or pedagogical but not the technological imperative that drives the technology integration agenda. The matrix is designed to be used after some initial research into an emerging technology. Once a technology is put through the matrix, a member of options are available： （1） shelving the technology; （2） putting the technology on hold and maintaining a watching brief until the technology matures in the market; and （3） researching the product further by conducting a trial or placing in testing sandpit. After further research, the technology can be tested as a pilot to determine how well or otherwise, the technology works within the institution. If an emerging technology has more than one product associated with it, a second and third step in the matrix has been developed, and the second step assigns a rating to each of the categories within the matrix. With many products containing similar features, a third step has been developed to compare products on a feature level.     

Fe^3＋掺杂TiO2可见光催化降解酸性红的研究

研究了在可见光条件下,用实验室合成的Fe3＋掺杂TiO2为催化剂催化降解酸性红染料,重点考察了Fe3＋的掺杂量、Fe3＋掺杂TiO2为催化剂的添加量、酸性红溶液的初始浓度、溶液pH值、光照时间对降解率的影响.实验结果表明,Fe3＋掺杂比为1.5%、催化剂用量为1.5 g/L、pH为2.0、质量浓度为40 mg/L的酸性红100 mL,用白炽灯光照降解酸性红30 min,酸性红降解率可达98.45%.

由潜抑到彰显——论老舍的民族归属意识

满族作家老舍的民族归属意识并非像沈从文和张承志等少数民族作家一样,始终自觉彰显,而是以解放前后为界,经历了由潜抑到彰显的转变历程。老舍一生都有着始终如一的满族归属意识,但在解放前一直处于一种压抑状态。直到解放后才开始彰显自己的民族归属意识。

A model for making decisions about ethical dilemmas in student assessment

In this mixed-methods study we investigated the development of a generalized ethics decision-making model that can be applied in considering ethical dilemmas related to student assessment. For the study, we developed five scenarios that describe ethical dilemmas associated with student assessment. Survey participants (i.e., educators) completed an online survey to express their decision-making process when faced with ethical dilemmas relating to student assessment. Based on the literature and the educators’ written responses to the scenarios, elements to consider in an ethics decision-making model related to student assessment include the following: (1) the critical incident giving rise to the ethical dilemma; (2) identification of the conflict elements; (3) decisions about the ethicality of the elements; (4) justification of the decisions; (5) implications; and (6) alternative suggestions. This model offers guidance to educators in considering the dimensions of an ethical dilemma in assessment prior to making a decision.     

转型时期校长决策思维的特点

转型时期，我国各级各类教育都面临着多元文化与多元经济的冲击。在复杂多变的国际和国内背景中，学校的生存与发展在很大程度上取决于校长的管理决策，而校长决策过程中的思维品质又将直接影响决策的效果。要提高校长决策思维水平，必须了解和研究决策思维的特点。该文从决策思维品质的四个方面论述了决策思维所体现的十二个特点。
