丁文姚  李健  韩毅 《图书情报工作》2019,63(22):118-128

[目的/意义] 探索期刊论文科学数据引用特征与规律不仅有助于描述学科领域对科学数据的利用情况，还能够揭示学术成果表达中的数据引用模式。[方法/过程] 以我国图书情报领域6种期刊2017年与2018年第一期刊载论文为样本，结合国家标准《信息技术科学数据引用》的引用元素，采用内容分析法从9个维度对样本论文的科学数据引用行为进行数据编码，应用统计学方法描述图书情报领域期刊论文科学数据引用特征并探索不同维度特征间的关联关系。[结果/结论] 图书情报领域期刊论文广泛引用来自国内外的统计整理类科学数据，对期刊论文中个人研究科学数据的引用量较大；科学数据引用标注方式与科学数据类型存在一定对应关系，但多样化的标注方式缺乏统一性；二手引用现象较为突出，二手引用程度与科学数据创建者类型相关。  相似文献   

Science notebooks as interactional spaces in a multilingual classroom: Not just ideas on paper     

Sara E.D. Wilmes  Christina Siry 《科学教学研究杂志》2020,57(7):999-1027

Past studies have explored the role of student science notebooks in supporting students' developing science understandings. Yet scant research has investigated science notebook use with students who are learning science in a language they are working to master. To explore how student science notebook use is co-constructed in interaction among students and teachers, this study examined plurilingual students' interactions with open-ended science notebooks during an inquiry science unit on condensation and evaporation. Grounded in theoretical views of the notebook as a semiotic social space, multimodal interaction analysis facilitated examination of the ways students drew upon the space afforded by the notebook as they constructed explanations of their understandings. Cross-group comparison of three focal groups led to multiple assertions regarding the use of science notebooks with plurilingual students. First, the notebook supported student-determined paths of resemiotization as students employed multiple communicative resources to express science understandings. Second, notebooks provided spaces for students to draw upon diverse language resources and as a bridge in time across multiple inquiry sessions. Third, representations in notebooks were leveraged by both students and teachers to access and deepen conceptual conversations. Lastly, students' interactions over time revealed multiple epistemological orientations in students' use of the notebook space. These findings point to the benefits of open-ended science notebooks use with plurilingual students, and a consideration of the ways they are used in interaction in science instruction.  相似文献   

Towards truly inclusive science education: a case study of successful curriculum innovation in a special school     

Jane Essex 《Support for Learning》2020,35(4):542-558

The paper provides a first person account of participant evaluation research of curriculum innovation in a school serving students with profound learning difficulties. It describes how the aspirations of the school leadership team to introduce science, combined with advisory support, overcame the initial anxiety of teaching staff about teaching an unfamiliar subject. The staff position was transformed and they gave a very positive evaluation of their experiences of teaching science, due to the impact of the subject on their students. The introduction of a distinct and inclusive model of science into the curriculum was ultimately found to have significant benefits for both students and staff.  相似文献   

Actions for sociopolitical consciousness in a high school science class: A case study of ninth grade class with predominantly indigenous students     

Bhaskar Upadhyay  Erin Atwood  Baliram Tharu 《科学教学研究杂志》2020,57(7):1119-1147

This case study explores how a group of Grade 9 students engaged in sociopolitical discourses and actions in a science class in a mostly indigenous student school in Nepal. The study used sociopolitical consciousness (SPC) as a framework to document and understand indigenous students’ SPC-oriented science interactions and subsequent social change actions. We used ethnographic methods of data collection over 6 months. The study focused on the actions of 4 girls and 2 boys belonging to the indigenous Tharu group. Data were analyzed using iterative qualitative methods. The study findings show that students are capable of engaging in critical thinking, critical reflecting, and taking actions for social change. Additionally, students are competent to link their experiences with social, structural, and political discrimination to the relevant science content they learn. The study presents four thematic findings related to SPC and science teaching and learning: Fostering social justice awareness in science class, fostering structural understanding of inequities in sickle cell disease, fostering sociopolitical actions for sickle cell disease, and the teacher's activist pedagogy for SPC in science learning. Implications of the study are that culturally relevant pedagogy helps indigenous students to become sociopolitically more aware of the links between science and social change. Adding aspects of critical pedagogies in science teaching could encourage students to become more sociopolitically reflective about science learning.  相似文献   

Automated Scoring of Constructed‐Response Science Items: Prospects and Obstacles     

Ou Lydia Liu  Chris Brew  John Blackmore  Libby Gerard  Jacquie Madhok  Marcia C. Linn 《Educational Measurement》2014,33(2):19-28

Content‐based automated scoring has been applied in a variety of science domains. However, many prior applications involved simplified scoring rubrics without considering rubrics representing multiple levels of understanding. This study tested a concept‐based scoring tool for content‐based scoring, c‐rater?, for four science items with rubrics aiming to differentiate among multiple levels of understanding. The items showed moderate to good agreement with human scores. The findings suggest that automated scoring has the potential to score constructed‐response items with complex scoring rubrics, but in its current design cannot replace human raters. This article discusses sources of disagreement and factors that could potentially improve the accuracy of concept‐based automated scoring.  相似文献   

维柯《新科学》的三个关键词     

冀志强 《唐山学院学报》2014,(5):25-27

在维柯的《新科学》中有三个关键词可以视为他所建立的这门新科学的理论支柱。这三个关键词是天神意旨、心头词典和诗性智慧。天神意旨是其新科学的理论背景,心头词典是其新科学的历史工具,诗性智慧是其新科学的核心成果。通过这三个关键词,可以从整体上更为深入地认识维柯所建立的新科学的历史地位和学术价值。同时,将这三个关键词结合起来整体思考,也可发现这其中有某些通常被人们所忽视的维度。  相似文献   

Toward an Ethical Rhetoric of the Digital Scientific Image: Learning From the Era When Science Met Photoshop     

Jonathan Buehl 《Technical Communication Quarterly》2014,23(3):184-206

Over the past two decades, scientific editors have attempted to correct “mistaken” assumptions about scientific images and to curb unethical image-manipulation practices. Reactions to the advent and abuse of image-adjustment software (such as Adobe Photoshop) reveal the complex relations among visual representations, scientific credibility, and epistemic rhetoric. Perelman and Olbrechts-Tyteca's model of argumentation provides a flexible system for understanding these relations and for teaching students to use scientific images ethically and effectively.  相似文献

教育研究中的系统科学进展与应用   总被引：1，自引：0，他引：1  

刘菊  钟绍春  解月光 《远程教育杂志》2011,29(1)

系统科学作为教育研究的重要方法论,也是教学系统设计的理论基础之一.它虽然已经历了一般系统论、自组织理论、复杂性理论三个发展阶段,但就目前教育理论研究情况来看,系统科学思想方法的教育应用仍多停留在一般系统论的初级阶段,对系统科学的新近研究成果显得不够重视,尤其是有着丰富内涵与教育应用巨大潜力的自组织理论代表--耗散结构理论.随着后现代主义教育研究的深入,耗散结构理论已越来越多地受到课程研究领域专家的重视,相关研究成果初步显现.另外,数字化学习理论Connectivism新近获得了较大发展,它的主要观点正是耗散结构理论主要思想方法的重要体现.由此,我们相信在系统梳理系统科学自身发展状况的基础上,研究系统科学代表性观点的教育应用已显得十分必要.另外,积极吸纳耗散结构理论的思想观点去分析教学系统,有助于从教育研究方法论的角度审视教育的弊病,查找深层次原因,摸索规律,促进信息时代教育的新发展.  相似文献
