Instructional methods and languages in class: A comparison of two teaching approaches and two teaching languages in the field of intercultural learning

The article presents the results of a quasi-experimental intervention study with a 2 × 2 factorial design. We implemented a problem-based intercultural learning unit in four secondary schools (grades 9 to 12) and varied the teaching approach (analytical/affective-experiential) and the language of instruction (German/English). The learning unit covered six 45-min lessons and was conducted in nine school courses (n = 143). Five additional school courses (n = 66) served as a control group. In all experimental groups, students engaged with critical incidents. These were either analysed (analytical focus) or acted out as role plays (affective-experiential focus). In addition, students analysed film clips (analytical focus) or participated in a simulation game (affective-experiential focus). The experimental groups outperformed the control group in the post-test, which required the analysis of critical incidents. Both teaching approaches were equally effective; however, students evaluated affective-experiential learning more positively. Using a foreign language for teaching did not impair performance.     

论董仲舒的天人观

董仲舒从自然,神性、人伦等方面论述了天的含义,并在此基础上,建构起他的一种独特的定宙模式。在这一定宙中,天、人乃至万物都是同源同类,它们以气中为中介,人循在应人事,相互感应,形成了从天地自然到人伦世事的一个完整世界。     

斑节对虾杆状病毒感染与水体理化因子

通过二造虾塘水体理化因子的检测和斑节对虾杆状病毒感染的调查，发现水体理化因子可影响斑节对虾杆状病毒的感染度，其中影响最大的是氨氮，其次是盐度和亚硝酸氮．氨氟和pH值有协同作用，硫化物可诱发斑节对虾杆状病毒病，亚硝酸氮可明显地抑制对虾的生长．     

《文心雕龙》与《论衡》谶纬观辨析

谶纬是图谶和纬书的合一,本非一类,谶出现较早,纬起源于西汉末期。《文心雕龙》和《论衡》都表达了对谶纬的看法,却有很大反差。刘勰、王充经学思想的不同是他们谶纬观差异的基础,《文心雕龙·正纬》篇不录王充即缘于此。《文心雕龙》和《论衡》分别着眼于文章写作与"疾虚妄",他们的谶纬观都是超越时代的。

合作技术创新的风险因素识别及模糊评价研究

合作创新因主体多样化而分散了创新风险,而合作创新过程中独有的风险及其复杂性和主观性、模糊性远未引起足够的重视。在对合作创新过程中风险因素进行识别的基础上,将合作创新的风险归纳为知识产权风险、合作关系风险和运作流程风险三大类,并结合合作创新风险项目的模糊性特点,运用模糊群体决策理论,建立了风险评价模型,同时给出了风险分析矩阵。

铁尾矿利用经济分析模型与应用

在技术及选矿工艺等因素的制约下,我国历史上铁矿资源回收率偏低,进而导致了大量铁尾矿的产生。目前,铁尾矿资源回收利用技术及设备问题已基本解决,而且铁精矿价格日益高涨,促使国内铁尾矿资源开发利用的外部条件日益成熟。尤其是在国内外铁矿石价格高企的今天,使得铁尾矿资源开发利用更加具有经济价值和可行性。在借鉴矿床经济品位计算原理的基础上,通过适当的类推及数学极限处理而导出了铁尾矿资源回收再选的经济分析模型。在广泛收集铁矿山相关经营参数及预计未来铁精矿价格走势的基础上,通过计算认为我国铁尾矿资源回收再选的临界品位定在7%是比较经济合理的,并提出了免除铁尾矿资源回收再选的税金及其基建投资贷款利息减半的政策优惠设想。     

Pre-service teachers’ attempts at debating contemporary issues in science education: A case study from Botswana

This paper constitutes an attempt to explore trends, issues and challenges that emerge when three different cohorts of pre-service teachers debate contemporary issues in science education at the University of Botswana. Apart from the author's experience of teaching the course, the impetus for this study also comes from a growing interest in the contemporary literature in the need for teachers who, in the context of globalization and knowledge economy, are ‘self-reforming’ through continually addressing the key issues of their profession. Unfortunately, the current situation is such that this burden of interrogation falls heaviest on teachers, despite their lack of skills in undertaking the task.     

绑架罪新论

绑架是一种常见行为,而在司法理论和司法实践中,关于绑架罪还有不少争议。研讨相关问题,对罪名、客体要件、客观要件和特殊主体的定罪量刑等,应该有更为清晰的思路。
