简谈化归思想在数学解题中的运用

本通过对大量数学解题方法的总结和归类，得出10种型数学解题的化归方法，并结合16个具体的数学解题问题，阐明了化归思想在数学解题中的运用。     

高职数学课程体系改革探索

培养具有创新精神与创造能力的高素质人才,全面提高学生的数学素质,切实加强应用数学的意识,构建数学系列课程中各门课程的结构、比例,达到知识结构合理、能力水平增加、综合素质提高的目的,以适应21世纪对各类人才的数学素质的要求.     

MM教育方式与当代数学教育

20世纪80年代至21世纪初,对数学教育改革和研究,这大浪淘沙式的严酷条件下,“MM教育方式”几乎是唯一存活下来,而且还在发展的一种教改方案.MM教育方式对当代数学教育的启示是:不能眼睛向外,看不到我们在数学教育方面的长处;要防止去“数学化”的倾向;要将数学教育理论研究与数学实践相结合.     

试论民国初年知识分子对实业发展的贡献

民国初年，知识分子较以往更多地投身实业。其对实业发展的贡献，主要表现在宣传、抵制国际经济侵略、挽回利权；和封建守旧势力作斗争，力图摆脱封建束缚；重视科技与管理，注重提高企业现代化水平；重视人才，注重培养人才；注重民族工商业间的相互扶持；等等。     

Mitigating the Effects of Poverty and Crime: the Long-Term Effects of an Early Intervention Programme for Children who were Developmentally Delayed and Prenatally Exposed to Cocaine

This study explores the long-term impact on participation in the Linda Ray Intervention Program (LRIP) for children (n = 54) who were developmentally delayed and prenatally exposed to cocaine. By identifying a group of programme graduates from a high crime/high poverty neighbourhood in Miami-Dade County using ArcGIS 10.2 software, a quasi-experimental design was used to compare children living in this area who participated in the centre-based modality (5 h a day; 5 days a week) to children living in this area who participated in the home-based modality (3 h per week) on their Florida Comprehensive Assessment Test (FCAT) reading and math scale scores in public school. The children who participated in the centre-based modality reported stronger outcomes in both math and reading FCAT scale scores at the p < .05 level and also out-performed their school-age peers on both math and reading FCAT scores at the p < .05 level.     

新课标下的数学课堂教学

数学课堂教学不仅是传授知识、形成技能、发展智力的过程,而更是教师引导学生经历数学化的过程,是促进学生全面、主动发展的过程,是承认学生差异、张扬学生个性的过程,是学生之间自主交流、合作探索的过程,是落实德育教育的过程,是理论知识和生活问题密切联系的过程,是数学课程资源的开发、利用、拓展的过程,是数学教师专业化发展的过程.     

Growing up in a tourist destination: developing an environmental sensitivity

Abstract

This paper explores how the socio-cultural milieu of a community may foster a sense of environmental stewardship among children and young people. Ethnographic fieldwork, carried out in a popular tourist destination in Australia, revealed that the overt impacts of tourism activity such as littering provoke negative feelings among children and young people; these perceptions can in turn translate into a sensitivity towards the environment. While debated in some circles, a Significant Life Experiences (SLE) lens is useful in understanding children and young people’s lived experiences of – and sensitivity to - environmental issues in the communities where they are raised. SLE is employed in this article to explore how a sense of stewardship towards the environment is developed among children and young people growing up in a tourist destination. Findings suggest they actively contribute to protecting the environment in a variety of ways from regular beach clean ups and educating visiting tourists to participating in rallies and anti-development protests.     

对1949至1952年间计划调节的历史考察

1949至1952年是我国国民经济的恢复阶段,也是多种经济成分并存,计划调节与市场调节相结合的新民主主义经济体制的运行阶段。就在这个过程中,因各种历史因素的推动,计划调节的机构逐步健全,计划调节的范围日益扩大,为高度集中的计划经济体制的形成打下了基础。
