In the United States today, urban schools serve the majority of high-poverty and high minority populations including large
numbers of Hispanic students. While many Hispanic students perform below grade level in middle school science, the science
teaching community as a whole is lacking elements of diversity as teachers struggle to meet the needs of all learners. Researchers
have recognized that science teacher effectiveness, one consequence of self-efficacy among teachers, is associated with future
science achievement and science-related careers of their students. This qualitative study explores how three science teachers’
effectiveness in the classroom impacts students’ science self-efficacy beliefs at one urban middle school. Hispanic students
were the focus of this investigation due to demographics and history of underperformance within this district. Teachers’ perspectives,
as well as outside observer evaluations of instructional strategies and classroom climates were triangulated to explore dynamics
that influence students’ interests and motivation to learn science using a framework to link teachers’ sense of efficacy (focusing
on student outcomes). Findings suggest the impact teacher effectiveness can have on student outcomes, including strengthened
student science self-efficacy and increased science achievement. Building awareness and support in teachers’ sense of efficacy,
as well as developing respectful and supportive relationships between educator/facilitator and pupil during the transition
to middle school may construct permanence and accomplishment for all in science. 相似文献

Science education in the United States will increasingly be driven by testing and accountability requirements, such as those mandated by the No Child Left Behind Act, which rely heavily on learning outcomes, or "standards," that are currently developed on a state-by-state basis. Those standards, in turn, drive curriculum and instruction. Given the importance of standards to teaching and learning, we investigated the quality of life sciences/biology standards with respect to genetics for all 50 states and the District of Columbia, using core concepts developed by the American Society of Human Genetics as normative benchmarks. Our results indicate that the states' genetics standards, in general, are poor, with more than 85% of the states receiving overall scores of Inadequate. In particular, the standards in virtually every state have failed to keep pace with changes in the discipline as it has become genomic in scope, omitting concepts related to genetic complexity, the importance of environment to phenotypic variation, differential gene expression, and the differences between inherited and somatic genetic disease. Clearer, more comprehensive genetics standards are likely to benefit genetics instruction and learning, help prepare future genetics researchers, and contribute to the genetic literacy of the U.S. citizenry. 相似文献

Throughout their lives, individuals accumulate and apply lessons learned from instruction and experience. It is unclear how they transfer these lessons to become accomplished in their fields. In this exploratory study, we develop grounded hypotheses about the relationship of transfer to accomplishment. Selected individuals told stories about what they learned that influenced their major accomplishments, their sources, and timing. Findings indicate that individuality is magnified on the road to accomplishment, although shared lessons were evident. Attitudes and values, adopted and applied, seemed to play a special role in the passage from transfer to accomplishment. 相似文献

人教版语文第一册中有四篇课文是以传递爱国主义价值观为宗旨的。选取其中《我多想去看看》作为研究对象,运用符际互补理论框架,研究如何通过文字和图像符号系统的相互作用和相互配合,形成连贯的语篇,分析结果表明,文字图像之间的符际关系着重在"国旗"、"地点"、"升旗仪式"以及"观礼"等方面;在小学语文教材中可以通过文字和图像符号系统的互补形成连贯的多模态语篇并传导主流价值观。 相似文献

This article offers a critique of Michael Young’s perspective on the Internet as it relates to the knowledge-driven curriculum he supports. I argue that the Internet is a site of both theoretical knowledge and everyday concepts which challenges the differentiation of knowledge that premises much of Young’s writing. Google searches from the perspective of a student and teacher show that theoretical knowledge with vertical links to subject and disciplinary communities as well as coherence built through links between concepts is fairly readily accessed on the Internet. The importance of information literacy for students, the critical need to curate content on the web, as well as the implications for the curriculum of framing ‘knowing’ as encompassing ‘being familiar’ and comprehending’ are highlighted. 相似文献
