Measuring the Impact of Gold and Green Open Access     

Li Zhang  Erin M. Watson 《The Journal of Academic Librarianship》2017,43(4):337-345

Using data from Web of Science, this research investigates how physical science researchers funded by the Canadian Institutes of Health Research complied with its open access policy, and compares the citation counts of articles published through gold and green models.It was found that, for articles published between 2008 and 2015, 9% were available through gold open access routes and 13% were available through green routes; most were not openly accessible. Citation rates were comparable for green open access and non-open access articles, but citation rates for gold open access articles were lower. After controlling for publication year, citation rates of gold, green, and non-open access articles were comparable. Among gold open access articles, citation rates were highest for open access journals with article processing charges, but after controlling for publication year, articles published in hybrid journals, followed by those in open access journals with article processing charges, achieved the highest citation rates. Articles published in free open access journals had the lowest citation rates. The results suggest that green open access is the most economical approach to comply with open access policies, and that it provides researchers with at least as much research impact as gold open access.  相似文献   

Gender Differences in Science: An Expertise Perspective     

Gita Taasoobshirazi  Martha Carr 《Educational Psychology Review》2008,20(2):149-169

The purpose of this paper is to propose a new approach to research on gender differences in science that uses the work on expertise in science as a framework for understanding gender differences. Because gender differences in achievement and participation in the sciences are largest in physics, the focus of this review is on physics. The nature of expertise is first discussed and a framework that focuses on factors that influence the emergence of expertise in physics is presented. This is used to interpret what is known about gender differences in science, particularly physics. Next, the potential contributions of the research on gender differences to our understanding of expertise are discussed. Using what is learned from these two areas of research, recommendations are made for future research examining gender differences in physics. It is suggested that such an approach be used for other areas of science, such as chemistry, where large gender differences in achievement and participation also exist.  相似文献   

Classroom Community and Peer Culture in Kindergarten     

Martha Lash 《Early Childhood Education Journal》2008,36(1):33-38

This study reflects a naturalistic, interpretive 5-month study in a public school morning kindergarten regarding the children’s social development and creation of a peer culture during the transitional months into public education. The main focus of the research was the children’s perspectives on these transitions and their evolving classroom community and peer culture in response to the teacher, classroom and school environment. This study captures the dynamic and complex flow of activity that occurs in classrooms, the give and take of relationships, and the agency that children take in developing peer culture as one piece of community. Elements of the peer culture that are foregrounded include secondary adjustments as realized in clean-up strategies, protecting play materials over time, and hypothetical competition with the afternoon kindergarten class.  相似文献   

Sample, Random and Variation: The Vocabulary of Statistical Literacy     

Jane M. Watson  Ben A. Kelly 《International Journal of Science and Mathematics Education》2008,6(4):741-767

This paper considers the development of school students’ ability to define three terms that are fundamental to statistical literacy: sample, random, and variation. A total of 738 students in grades 3, 5, 7, and 9 were asked in a survey to define and give an example for the word “sample.” Of these, 379 students in grades 7 and 9 were also asked about the words “random” and “variation.” Responses were used to describe developmental levels overall and to document differences across grades on the understanding of these terms. Changes in performance were also monitored after lessons on chance and data, emphasizing variation for 335 students. After 2 years, 132 of these students and a further 209 students who were surveyed originally but did not take part in specialized lessons, were surveyed again. The difference after 2 years between the performance of students who experienced the specialized lessons and those who did not was considered, revealing no differences in performance longitudinally. For students in grades 7 and 9, the association of performance on the three terms was explored. Implications for mathematics and literacy educators are discussed.  相似文献   

Anatomy as a Model Environment for Acquiring Professional Competencies in Medicine: Experiences at Harvard Medical School     

Katherine G. McDaniel  Taylor Brown  Caitlin C. Radford  Cynthia H. McDermott  Trudy van Houten  Martha E. Katz  Dana A. Stearns  Sabine Hildebrandt 《Anatomical sciences education》2021,14(2):241-251

Anatomy education provides students with opportunities to learn structure and function of the human body, to acquire professional competencies such as teamwork, interpersonal skills, self-awareness, and to reflect on and practice medical ethics. The fulfillment of this wide potential can present challenges in courses that are part of an integrated curriculum and shorter than traditional courses. This new reality, together with students' increasing concern about the stresses within medical education, led to efforts at Harvard Medical School to implement practical steps toward an optimal learning environment in anatomy. These were based on core elements of ethical anatomy education and principles of trauma-informed care. Anatomy is conceptualized here as the “first clinical discipline,” with relational interactions between anatomical educators, medical students, and body donors/patients. Essential prerequisites for the implementation of this work were support by the medical school leadership, open partnership between engaged students and faculty, faculty coordination, and peer-teaching. Specific interventions included pre-course faculty development on course philosophy and invitations to students to share their thoughts on anatomy. Student responses were integrated in course introductions, combined with a pre-dissection laboratory visit, an introductory guide, and a module on the history and ethics of anatomy. During the course, team-building activities were scheduled, and self-reflection encouraged, for example, through written exercises, and elective life-body drawing. Students' responses to the interventions were overall positive, but need further evaluation. This first attempt of a systematic implementation of an optimal learning environment in anatomy led to the identification of areas in need of adjustment.  相似文献   

Assessment of Students’ Understanding of Variation     

Jane M. Watson  Ben A. Kelly 《Teaching Statistics》2007,29(3):80-88

Several tasks used in research studies are presented with assessment rubrics and examples of the development of student understanding. The tasks focus on students’ appreciation of variation in several contexts and illustrate the need to discuss variation in the classroom and to ask students specifically about it during assessment.  相似文献   

Community-based inquiry improves critical thinking in general education biology          下载免费PDF全文

Quitadamo IJ  Faiola CL  Johnson JE  Kurtz MJ 《CBE life sciences education》2008,7(3):327-337

National stakeholders are becoming increasingly concerned about the inability of college graduates to think critically. Research shows that, while both faculty and students deem critical thinking essential, only a small fraction of graduates can demonstrate the thinking skills necessary for academic and professional success. Many faculty are considering nontraditional teaching methods that incorporate undergraduate research because they more closely align with the process of doing investigative science. This study compared a research-focused teaching method called community-based inquiry (CBI) with traditional lecture/laboratory in general education biology to discover which method would elicit greater gains in critical thinking. Results showed significant critical-thinking gains in the CBI group but decreases in a traditional group and a mixed CBI/traditional group. Prior critical-thinking skill, instructor, and ethnicity also significantly influenced critical-thinking gains, with nearly all ethnicities in the CBI group outperforming peers in both the mixed and traditional groups. Females, who showed decreased critical thinking in traditional courses relative to males, outperformed their male counterparts in CBI courses. Through the results of this study, it is hoped that faculty who value both research and critical thinking will consider using the CBI method.  相似文献

Abdulkadir Haktanir  A. Stephen Lenz  Nesime Can  Joshua C. Watson 《International journal for the advancement of counseling》2016,38(4):286-297

This study reports the development and evaluation of a Turkish-language version of three positive psychology assessments for use in clinical, education and research settings with Turkish-speaking individuals. A multistage translation of the Brief Resilience Scale (BRS; Smith et al. in International Journal of Behavioral Medicine, 15, 194–200, 2008), the General Mattering Scale (GMS; Marcus 1991) and the Short Grit Scale (GS; Duckworth & Quinn in Journal of Personality Assessment, 91, 166–174. doi:10.1080/00223890802634290, 2009) is detailed, as well as the procedure used to evaluate the internal structure of the translated assessments. The results yielded from data of 268 participants indicated factor structures ranging from acceptable to robust model fit for the BRS, GMS, and GS. Implications for counseling practice and future research are discussed.  相似文献

秦始皇兵马俑博物馆室内含硫颗粒物的SEM-EDX研究     

胡塔峰  曹军骥  李旭祥  董俊刚  沈振兴  Shun-Cheng Lee  Judith C.Chow  John G.Watson  容波 《中国科学院研究生院学报》2007,24(5):564-570

本文对秦始皇兵马俑博物馆室内采集的长短期降尘、大气悬浮颗粒物和彩绘漆层进行了SEM-EDX研究，在大气悬浮颗粒、短期和长期降尘中，含硫颗粒的粒径分别为0.9～22.8μm、1.0～29.0μm和1.2～37.7μm，多为石膏与粘土或石英以内部混合的状态存在。降尘中的附着型絮状硫酸钙多于大气悬浮颗粒物中，显示降尘和大气中的二氧化硫发生了累进的化学反应。彩绘漆层表面的坑和裂隙附近观察到原位生长的硫酸钙晶体，显示漆层材料或降尘颗粒物与大气二氧化硫之间的酸化学反应，可能是彩绘漆层表面受侵蚀形成微小坑和裂隙的原因之一。  相似文献
