System-wide improvement of early-grade mathematics: New evidence from the Gauteng Primary Language and Mathematics Strategy

This article reports on a two-year evaluation of the Gauteng Primary Language and Mathematics Strategy (GPLMS), an innovative system-wide reform intervention designed to improve learning outcomes in Gauteng Province, South Africa. Using data from universal testing of all learners in 2008 on a provincial systemic evaluation, as well as data from the 2011, 2012 and 2013 Annual National Assessment tests, this article investigates whether or not the GPLMS improves the numeracy skills of learners in early-grade mathematics in underperforming schools. Using as identification strategy, the natural experiment that resulted from a miscalculation of the provincial systemic evaluation test scores in 2008, which had been used to assign schools to the GPLMS intervention, the study shows that the GPLMS intervention is positively associated with improvements in early-grade mathematics performance of schools in the neighbourhood around the assignment threshold. The findings of the study contribute to the growing body of knowledge that shows the effectiveness of combining lesson plans, learner resources, and quality teacher capacity building.     

延安精神对高校思想政治理论课教育教学的启示

延安是中国革命的圣地和新中国的摇篮,也是中国共产党人的精神家园。中国共产党不仅在延安时期实现了马克思主义中国化的第一次历史性飞跃,确立了毛泽东思想的指导地位,而且培育和形成了伟大的延安精神。在党和国家高度重视大学生思想政治教育、进一步加强和改进高校思想政治理论课教育教学的新形势下,弘扬延安精神既是思想政治理论课教育教学的重要内容,也对高质量地开展思想政治理论课教育教学具有深刻的启示和方法论指导。     

Smart structures and materials

A structure is an assembly that serves an engineering function. It is reasonable to expect that all engineering design should be smart, and not dumb. But one can still make a distinction between smartly designed structures and smart structures. The latter term has acquired a specific technical meaning over the last few decades. A smart structure is that which has the ability to respond adaptively in a pre-designed useful and efficient manner to changes in environmental conditions, including any changes in its own condition; the response is adaptive in the sense that two or more stimuli or inputs may be received as anticipated and yet there is a single response function as per design. Smartness ensures that the structure gives optimum performance under a variety of environmental conditions. While structures with some degree of smartness have been designed from times immemorial, the current activity and excitement in this field derives its impetus from the level of sophistication achieved in materials science, information technology, measurement science, sensors, actuators, signal processing, nanotechnology, cybernetics, artificial intelligence, and biomimetics.     

中国近代三次禁烟运动之比较

近代中国鸦片烟毒泛滥成灾，因此，中国人民曾多次掀起全国性的禁烟禁毒运动。大规模的禁烟运动有三次，即林则徐禁烟运动、清末明初禁烟运动和国民政府“二年禁毒、六年禁烟”运动。这些运动发生的国内处背景、禁烟措施、效果以及民众的表现，都有不同。虽然，这些运动终未能彻底解决烟毒问题，但经验教训却可供后世借鉴。

高中英语写作教学反思与设计案例分析——一项基于高中英语教师培训数据的研究

写作教学从来都是外语教学的重点和难点。通过教师培训的反思数据分析可见,高中英语教师对写作教学改革在理念上新旧共存,情感上冷热不一;从教学设计的数据看,教师在专业知识和技能上良莠不齐。因此,有必要消除教师心理障碍,激发教师学习热情,开发多元化职后学习和教育模式来推动教师参与课改和教改。
