The goal of this study was to define the construct and establish the validity of disciplinary literacy, which has recently gained attention from the implementation of the Common Core State Standards (National Governors Association Center for Best Practices & Council of Chief State School Officers in Common Core State Standards for English language arts & literacy in history/social studies, science, and technical subjects [PDF]. Authors, Washington, DC, 2010). After defining disciplinary literacy in the four core disciplines of English language arts, science, history and social studies, and mathematics, scales were developed and administered to a snowball sample of professionals nationwide, with 857 respondents. The data showed evidence of disciplinary literacy as a multidimensional construct with three related factors: source literacy, analytic literacy, and expressive literacy. Based on EFA and CFA results, we can conclude that there are at least three types of literacy in operation among the four core disciplines. The three factors of literacy varied significantly by the four core disciplines of English/language arts (ELA), science, history and social studies, and mathematics, supporting the notion that each discipline uses literacy uniquely. This is the first study of its kind to attempt to define, quantify, and validate the construct of disciplinary literacy.  相似文献

教师专业化与教师应对教育改革的能力   总被引:1,自引:0,他引:1  
本文论述的是中国教育改革发展变化过程中的教师专业化问题,所以提出这一问题的背景,是联合国教科文组织讨论了“全民教育”的各项活动和中国教育改革.当前教育改革的目的,在于提高个体和全民发展的能力.因此,教育质量成为人们日益关注的重要问题.教师的工作职能是要推动教育改革的各项措施得到实施.本文认为,“信息时代”的要求和“知识经济”的兴起,使人们对人才的特点有了新的理解,也证实了在教育儿童和青少年成为未来工作者和公民方面存在的不足.综观中国教育改革,它是一个被迫出现的过程,导致学校对教育改革的反应不灵敏.教师作为专业人员,应该支持改革,但是他们的效能还是存在一定的问题.本文进一步认为,中国教师当前面临的主要问题是不具备应对改革的能力.有关研究表明,教师工作的本质及其关注的问题与教育改革的预期大相径庭.这一问题即使通过行政命令、在职培训、或者投入更多的教育资源也难以解决.本文认为,进行全面改革的同时,要改革学生评价和选拔制度,从文化和社会层面上来思考教师职业,树立新的教师专业发展理念.  相似文献

This essay considers the question of why we should teach science to K-2. After initial consideration of two traditional reasons for studying science, six assertions supporting the idea that even small children should be exposed to science are given. These are, in order: (1) Children naturally enjoy observing and thinking about nature. (2) Exposing students to science develops positive attitudes towards science. (3) Early exposure to scientific phenomena leads to better understanding of the scientific concepts studied later in a formal way. (4) The use of scientifically informed language at an early age influences the eventual development of scientific concepts. (5) Children can understand scientific concepts and reason scientifically. (6) Science is an efficient means for developing scientific thinking. Concrete illustrations of some of the ideas discussed in this essay, particularly, how language and prior knowledge may influence the development of scientific concepts, are then provided. The essay concludes by emphasizing that there is a window of opportunity that educators should exploit by presenting science as part of the curriculum in both kindergarten and the first years of primary school.  相似文献

Results are reported in this paper from a study aimed at evaluating significant competencies in final-year students of some engineering programmes in Chile. The study was carried out by a group of eight universities that were interested in exploring ways to assess learning outcomes such as those demanded by the recent Chilean accreditation system. The authors actively participated in all stages of the study, contributing directly to the design, application and results evaluation of some tests. A sample of 150 students was tested, under conditions that guaranteed the comparability of results. In this paper the authors present results relating to the evaluation of effective communication. The study was backed up by a conceptual model and some hypotheses that are explained and discussed in this work.  相似文献

ABSTRACT

The aim of this article is to examine how EU lifelong learning policies are trying to reach the vulnerable by looking at what measures against social exclusion they offer and how equitable these measures are. It is a qualitative study that focuses on policy documents that form the European Union’s legal and political frameworks of reference in the lifelong learning area since 1992. The document analysis has been complemented by semi-structured interviews with EU lifelong learning experts. The findings show that early school leavers and migrants are the main target groups in the policies, leaving many other groups at risk of being excluded from learning opportunities. There is not enough attention to measures addressing wider social phenomena. There is also an overemphasis on basic skills which are understood in a very narrow way as literacy and numeracy when referring to the vulnerable. We argue that a greater variety of measures as well as better targeted measures are needed to address the multiple and complex needs of the vulnerable. Such measures would allow a broader understanding of lifelong learning where those that are hardest to reach are offered learning opportunities independent of their personal and social circumstances  相似文献

Reflective journals have been widely accepted throughout various educational disciplines for many years as a means of enhancing experiential learning practices. Reflective journals allow for students to gain a better understanding of a given experience and explore the levels of critical thinking as they work through the understanding and learning processes. Critical thinking involves the logical progression from mere knowledge and understanding to the highest levels of synthesis and evaluation. The immediate study presents findings of the analyses of a series of sequential reflective journals presented over the course of a semester-long internship experience. Findings indicate that reflective journals are shown to facilitate progression through the levels of critical thinking as identified in Bloom’s taxonomy and promote a higher level of understanding and application of theoretical concepts to practical experiential learning.  相似文献

Genetic determinism can be described as the attribution of the formation of traits to genes, where genes are ascribed more causal power than what scientific consensus suggests. Belief in genetic determinism is an educational problem because it contradicts scientific knowledge, and is a societal problem because it has the potential to foster intolerant attitudes such as racism and prejudice against sexual orientation. In this article, we begin by investigating the very nature of belief in genetic determinism. Then, we investigate whether knowledge of genetics and genomics is associated with beliefs in genetic determinism. Finally, we explore the extent to which social factors such as gender, education, and religiosity are associated with genetic determinism. Methodologically, we gathered and analyzed data on beliefs in genetic determinism, knowledge of genetics and genomics, and social variables using the “Public Understanding and Attitudes towards Genetics and Genomics” (PUGGS) instrument. Our analyses of PUGGS responses from a sample of Brazilian university freshmen undergraduates indicated that (1) belief in genetic determinism was best characterized as a construct built up by two dimensions or belief systems: beliefs concerning social traits and beliefs concerning biological traits; (2) levels of belief in genetic determination of social traits were low, which contradicts prior work; (3) associations between knowledge of genetics and genomics and levels of belief in genetic determinism were low; and (4) social factors such as age and religiosity had stronger associations with beliefs in genetic determinism than knowledge. Although our study design precludes causal inferences, our results raise questions about whether enhancing genetic literacy will decrease or prevent beliefs in genetic determinism.  相似文献

This article presents a historical account of the development of electronic devices along with an appreciation for the physics of semiconductors. Starting at the turn of the century with the work of J C Bose on Galena, the article leads us to recent low temperature experiments at IBM to demonstrate single electron transistors.  相似文献
