作者根据我国城市化道路的基本方针 ,运用社会学的社区研究方法 ,对贵州省德江县煎茶镇集镇建设的情况进行了考察调研 ,通过对煎茶镇集镇建设 1 5年取得的成就分析 ,认为贵州省在西部大开发中 ,只有走小城镇带动战略的振兴之路 ,才能迎头赶上东部地区的发展。同时分析了集贸型小城镇的弱点 ,认为贵州要振兴 ,应该按费孝通教授指出的大力发展庭院经济 ,完成“公司 +基地 +农户”的发展阶段 ,同时要学习借鉴东部城镇建设的经验 ,将集贸型小城镇逐步改造成工业型、贸易型、特色型小城镇 ,大、中、小城镇合理布局 ,协调发展 ,与长江流域、珠江流域的城市群融为一体 ,贵州才能实现全面振兴的目标。 相似文献

Retractions serve as one perspective of the publishing process, and can offer vast insight into the problems associated with basic research, with the traditional publishing platform, or with policies. Some established retraction guidelines exist, such as those established by the Committee on Publication Ethics, or COPE. This essay provides a perspective of stealth or silent retractions within the broader concept of retractions, and within the framework of the COPE retraction guidelines. The issue of opaque retraction notices, especially in the case of COPE members, as well as the prominence of questionable retraction policies among select “predatory” open access publishers, is emphasized. Select clear examples are provided. 相似文献

This essay provides an unpalatable perspective on classifying the reluctance of authors, editors or publishers to correct their erroneous literature as being unethical. Authors who publish papers that carry errors and who take laurels for such publications, but who then fail to correct reported errors at a post-publication stage should be classified as unethical, and their act or irresponsibility as misconduct. Similarly, editors and publishers who fail to revise erroneous literature when claims are factually correct, independent of the volume of claims, are also in violation of their codes of conduct and professional responsibilities towards the scientific community and society. This essay provides a critical outlook on this issue which has begun to plague the post-publication movement in science, and which deserves urgent attention and focus. 相似文献

AbstractThis article reports on a longitudinal study spanning over 5 years, involving the design and implementation of an early childhood teacher education program model that engages a critical-ecological theoretical approach, a funds of knowledge perspective, and design-based methodology. This project aimed to promote equitable education for all children, and especially for young immigrant children encountering situations of oppression within the national and local educational contexts in Arizona. In this teacher education program, families, community members, researchers, pre-service teachers and teachers worked together to develop new modes of curricular activity, new spaces, new relationships, and new forms of movement among participants, as well as new circulations of literacy artefacts. 相似文献

The dialogue that occurs in science classrooms has been the subject of research for many decades. Most studies have focused on the actual discourse that occurs and the role of the teacher in guiding the discourse. This case study explored the neglected perspective of secondary science students and their beliefs about their role in class discussions. The study participants (N? =? 45) were students in one of the three differentially tracked chemistry classes taught by the same teacher. Findings about the differences that exist among students from different academic tracks are reported. While it seems that epistemological beliefs focusing on content are common for the students in this study, the students' social framing in the different tracks is important to consider when teachers attempt to transition to more dialogic forms of discourse. Some key findings of this study are (a) students’ beliefs that science is a body of facts to be learned influenced the factors they deemed important for whole-class discussion, (b) students from the lower-level track who typically were associated with lower socioeconomic status were more likely to view their role as passive, and (c) students’ comfort level with the members of the class seemed to influence their decisions to participate in class discussions. 相似文献

Satellite remote sensing techniques can be used for conducting environmental change detection studies following a natural disaster. Modern computer technology and free access to global satellite imagery allows educators to introduce undergraduate students to the fields of remote sensing and encourage their scientific participation through a research assignment that also serves as an educational exercise. The undergraduate physical science laboratory manuals used in higher education that contain printed remote sensing material often fail to effectively achieve these goals. This class exercise utilizes digital satellite imagery for studying the floods that resulted in the Paraná River region in South America during El Niño 1997–98. In addition, it examines vegetation cover and spectral profiles from the study area in order to further understand and assess the changes that were caused by this recurrent climatic anomaly. 相似文献

After one year of implementation, this paper describes a programme designed to support literacy learning in low performing schools from poor sectors in Santiago, Chile. School‐based intensive training on theory and practice of a literacy learning framework for classroom instruction and long‐term support were used to impact the achievement of students from disadvantaged families in 16 kindergarten classrooms and 16 1st‐grade classrooms in nine primary schools. Preliminary results showed an improvement in learning achievement positively related to level of implementation of the literacy instruction framework in the classrooms and teachers' perception of an improvement in their knowledge and classroom practices. Although findings from this study cannot support definite conclusions, because of the lack of experimental conditions, they provide relevant information for future experimental studies on how to meet the literacy learning needs of children from disadvantaged backgrounds. 相似文献
