In much of the educational literature, researchers make little distinction between African-American students and students
of the African Diaspora who immigrated to the United States. Failing to describe these salient student differences serves
to perpetuate an inaccurate view of African-American school life. In today’s large cities, students of the African Diaspora
are frequently learning science in settings that are devoid of the resources and tools to fully support their success. While
much of the scholarship unites these disparate groups, this article details the distinctive learning culture created when
students from several groups of the African Diaspora learn biology together in a Brooklyn Suspension Center. Specifically
this work explains how one student, Gabriel, functions in a biology class. A self-described black-Panamanian, Gabriel had
tacitly resigned to not learning science, which then, in effect, precluded him from any further associated courses of study
in science, and may have excluded him from the possibility of a science related career. This ethnography follows Gabriel’s
science learning as he engaged in cogenerative dialogue with teachers to create aligned learning and teaching practices. During
the 5 months of this research, Gabriel drew upon his unique lifeworld and the depth of his hybridized cultural identity to
produce limited, but nonetheless important demonstrations of science. Coexistent with his involvement in cogenerative dialogue,
Gabriel helped to construct many classroom practices that supported a dynamic learning environment which produced small yet
concrete examples of standards based biology. This study supports further investigation by the science education community
to consider ways that students’ lifeworld experiences can serve to structure and transform the urban science classroom.
The development of services provided by the National Library of Medicine (NLM), which dates back to 1836, is described. MEDLINE, a database of 10-plus million references and abstracts to the world's biomedical literature, was put on the World Wide Web for free searching in 1997 as a system called PubMed, whose use has grown to over 250 million searches per year. PubMed features a variety of links between MEDLINE references and related information – full-text journal articles, DNA sequence data, medical knowledge bases, etc. – at websites within and outside NLM. PubMed is a major component of a larger NLM system, Entrez, which integrates access to a number of genome-related databases with linking features similar to those of PubMed. The newest linked service, which became a reality in February 2000, is PubMed Central, the National Institutes of Health's free repository for primary research reports in all the life sciences. 相似文献
For almost a half century David F. Treagust has been an exemplary science educator who has contributed through his dedication and commitments to students, curriculum development and collaboration with teachers, and cutting edge research in science education that has impacted the field globally, nationally and locally. A hallmark of his outstanding career is his collaborative style that inspires others to produce their best work. 相似文献
The study aimed to develop a meaning-based adult day care program managed by nurses for Filipino older persons. Meaning-based nursing care is intended to serve as a guide in creating meaningful, focused, and structured activities for nurses in adult day care.
A mixed methods research design was used in the study. This method involved the development of a training module, meaning-based nursing care, training of registered nurses, training evaluation of nurses, and referral for interdisciplinary team meetings and consultations. Meaning-based care was approaches that address the meaning of experiences for older persons in the process of conducting adult day care services.
The study gave evidences to the ability of nurses to manage a program for older persons. Thus, the study recommends the use of the nursing model developed to prescribe guidelines in the conduct of meaning-based adult day care programs and services. 相似文献
Breaktimes are ubiquitous in English schools. Research suggests they have social value for children, but school staff often have a range of concerns about breaktimes and tend to undervalue them. However, there is little understanding about these times, not least because data are not collected about their organisation and characteristics. This paper brings together data from three national surveys undertaken in 1995, 2006 and 2017 of head teachers of primary and secondary schools to provide an understanding of the nature, organisation and staff attitudes towards breaktimes and how they have changed over 25 years. At each survey point, completed questionnaires were received from representative random samples of over 1000 primary and secondary schools. Results showed marked reductions in the average total amount of time for breaks, the virtual abolition of afternoon breaks and a decline in time available for lunchtime breaks. The reductions were largely for behavioural reasons and to increase time for learning. Results also show variations in the length of breaktimes across school types and in relation to socioeconomic disadvantage, and changes to the amount of supervision provided by schools. Attitudes towards breaks varied across primary and secondary phases, and the withholding of breaks was used by schools to address poor pupil behaviour and disengagement. Schools continued to have concerns about the management of behaviour during breaktimes, even when breaks had already been shortened. It is suggested that staff undervalue the potential contribution that breaktimes afford the development and wellbeing of children and young people in school. 相似文献
