Language is a means of communication.Without language,it would beimpossible for people to communicate,and the society would break down.However,language is not a simple,single code used in the same manner byall people in all situations, It is a very complicated social phenomenon. It isthe most characteristically human of all human activities. It enters naturallyand essentially into virtually everything we do, from greeting an acquaintanceto making a trip on the moon.Therefore, a careful study of the languagevariation might help us to understand the relationship betweem language andsociety better.  相似文献

Grouping children of different ages in the same preschool classroom (i.e., mixed age) is widespread, but the evidence supporting this practice is mixed. A factor that may play a role in the relation between classroom age composition and child outcomes is peer skill. This study used a sample of 6,338 preschoolers (ages 3–5) to examine the influence of both classroom age composition and peer skill on children’s behavioral and language outcomes. Results supported the growing literature indicating preschoolers’ skills are higher when peer skill is higher, but differences related to classroom age composition were not found. These findings further support the view that peer skill plays an important role in preschool children’s outcomes.  相似文献

This paper is a reflection on a three-year longitudinal study that explored the development of children’s concept of a substance, for which detailed results concerning children’s understandings have been reported elsewhere. The attention in this paper is on the methodological features related to the longitudinal nature of the study and the insights into pupils’ learning that were afforded by its design. There is, of course, an extensive literature on children’s understandings of scientific ideas, and the nature of conceptual change involved in learning is a contested area. I argue in the paper that longitudinal studies are uniquely placed to inform the debate, and by focusing on this particular study the aim is to demonstrate the kind of contribution that can be made.  相似文献

This qualitative case study looks closely at an elementary teacher who participated in professional development experiences that helped her develop a hybrid practice of using inquiry-based science to teach both science content and English language development (ELD) to her students, many of whom are English language learners (ELLs). This case study examines the teacher’s reflections on her teaching and her students’ learning as she engaged her students in science learning and supported their developing language skills. It explicates the professional learning experiences that supported the development of this hybrid practice. Closely examining the pedagogical practice and reflections of a teacher who is developing an inquiry-based approach to both science learning and language development can provide insights into how teachers come to integrate their professional development experiences with their classroom expertise in order to create a hybrid inquiry-based science ELD practice. This qualitative case study contributes to the emerging scholarship on the development of teacher practice of inquiry-based science instruction as a vehicle for both science instruction and ELD for ELLs. This study demonstrates how an effective teaching practice that supports both the science and language learning of students can develop from ongoing professional learning experiences that are grounded in current perspectives about language development and that immerse teachers in an inquiry-based approach to learning and instruction. Additionally, this case study also underscores the important role that professional learning opportunities can play in supporting teachers in developing a deeper understanding of the affordances that inquiry-based science can provide for language development.  相似文献

Abstract

This article discusses the resource implications of Malawi’s new language-in-education policy. Whilst previous publications on the English as a medium of teaching and learning policy, which was announced in Malawi in 2014, have sharply criticised and dismissed the new language policy from pedagogical and other educational grounds, the current article is the first to dwell exclusively on the resource implications of the new language policy. The qualitative study reported on, which utilised Barron’s learning ecologies framework, was based on information drawn from one key informant; readers’ comments extracted from a Malawian online newspaper; and some scholarly publications. The article argues that the available resources are too inadequate to lead to a successful implementation of English as a medium of teaching and learning in the non-English-dominant Malawi. The article recommends that Malawi should return to the previous language policy, which was UNESCO compliant, and that adequate and enabling resources be channelled to improving the teaching and learning of English as a subject. Resources should also be injected into the professional development of teachers in order to capacitate them to effectively handle English as a medium of teaching and learning from Grade 5 onwards.  相似文献

It is complicated to design a computer simulation that adapts to students with different characteristics. This study documented cases that show how college students’ prior chemistry knowledge level affected their interaction with peers and their approach to solving problems with the use of computer simulations that were designed to learn electrochemistry. Students with different prior knowledge levels were found to use different approaches to solving problems with the use of computer simulations. In particular, the cases showed that students with a high level of prior knowledge tended to use the equations and formulas to accomplish the learning tasks and then use the computer simulations to confirm their predictions. Students with a low level of prior chemistry knowledge used the computer simulations as the main resources to accomplish their tasks. Considerations of individual differences and the integration of learning materials were suggested for further research on instructional use of computer simulations.  相似文献

The inclusion of the history of science in science curricula—and specially, in the curricula of science teachers—is a trend that has been followed in several countries. The reasons advanced for the study of the history of science are manifold. This paper presents a case study in the history of chemistry, on the early developments of John Dalton’s atomic theory. Based on the case study, several questions that are worth discussing in educational contexts are pointed out. It is argued that the kind of history of science that was made in the first decades of the twentieth century (encyclopaedic, continuist, essentially anachronistic) is not appropriate for the development of the competences that are expected from the students of sciences in the present. Science teaching for current days will benefit from the approach that may be termed the “new historiography of science”.  相似文献

Science teaching environments are social environments, and teachers emotions interact with their science teaching in powerful ways. To value the teacher is to value the whole person, not just the intellect. In this paper, a theorization of teacher emotion in science teaching is developed which illustrates the role of emotion in establishing and maintaining self-esteem in science teaching situations. From the standpoint of social-constructionist theory of emotion, it is argued that emotion is a social construction within social relationships. Arising from this view, are the emotions of intellectual excitement, frustration and shame that play a key role in the development of self-esteem. The dynamics of these emotions, in the context of experiences of success and failure, may dispose teachers to act positively or negatively towards science teaching. The theorisation developed is illustrated in the emotional experiences of an elementary school teacher in an early childhood science classroom. These experiences indicate that emotion is constitutive of teaching, and merits greater consideration in science teaching.  相似文献

There are many factors that shape students’ attitudes toward science, technology, engineering and mathematics. This exploratory study of high school students examined the effect of enriching chemistry with math on chemistry students’ attitudes toward math and careers involving math. To measure student attitudes, a survey was administered before and after the 18-week chemistry class; results from the chemistry class were compared to survey results from students in an elective science class that did not emphasize mathematics. At the end of the 18-week period, only the chemistry students exhibited more positive views toward their abilities in mathematics and careers that involve mathematics, as compared to their views at the outset of the course. To ensure that chemistry mastery was not hindered by the additional emphasis on math, and that mastery on state end-of-course examinations reflected knowledge acquired during the math-intensive chemistry class, a chemistry progress test was administered at the start and end of the term. This exploratory study suggests that emphasizing mathematical approaches in chemistry may positively influence attitudes toward math in general, as well as foster mastery of chemistry content.  相似文献

This study investigates the beliefs and practices of seven high school chemistry teachers as a result of their participation in a year-long inquiry professional development (PD) project. An analysis of oral interviews, written reflections, and in-class observations were used to determine the extent to which the PD affected the teachers’ beliefs and practice. The data indicated that the teachers developed more complete conceptions of classroom inquiry, valued a “phenomena first” approach to scientific investigations, and viewed inquiry approaches as helpful for facilitating improved student thinking. Analysis of classroom observations with the Reformed Teaching Observation Protocol indicated that features of the PD were observed in the teachers’ practice during the academic year follow-up. Implications for effective science teacher professional development models are discussed.  相似文献

This article charts the progress of one cohort of student‐teachers (variously known as beginning teachers and pre‐service teachers) training to teach English in London secondary schools during 2008–9. The research focuses specifically on the experiences which facilitate their development as confident and creative teachers and assessors of reading at Key Stage 3 (11–14 years). Findings indicate that it is the interaction – and tensions – between their personal reading histories, engagement in theory, and practice within the social environment of the classroom which shape their burgeoning identities as teachers of literature and reading. This year‐long study demonstrates that for some a growing confidence has enabled them to look beyond approaches advocated by statutory curriculum frameworks to develop their own view of innovative practice in the teaching of reading.  相似文献

Books I and III of Newton’s Principia develop Newton’s dynamical theory and show how it explains a number of celestial phenomena. Book II has received little attention from historians or educators because it does not play a major role in Newton’s argument. However, it is in Book II that we see most clearly Newton both as a theoretician and an experimenter. In this part of the Principia Newton dealt with terrestrial rather than with celestial phenomena and described a number of experiments he carried out to establish the success of his theory in explaining the properties of fluid resistance. It demonstrates most clearly the activities of a scientist working at the forefront of knowledge and working with phenomena which he did not fully understand. In this paper the first of Newton’s set of experiments into fluid resistance are described and the theory which underlies his explanation is outlined. A number of issues arising from this portion of the Principia together with implications for teaching about the nature of science are discussed.  相似文献

Research Findings: This study explored the relations between Spanish–English dual language learner (DLL) children’s home language and literacy experiences and their expressive vocabulary and oral comprehension abilities in Spanish and in English. Data from Spanish–English mothers of 93 preschool-age Head Start children who resided in central Pennsylvania were analyzed. Children completed the Picture Vocabulary and Oral Comprehension subtests of the Batería III Woodcock–Muñoz and the Woodcock–Johnson III Tests of Achievement. Results revealed that the language spoken by mothers and children and the frequency of mother–child reading at home influenced children’s Spanish language abilities. In addition, the frequency with which children told a story was positively related to children’s performance on English oral language measures. Practice or Policy: The findings suggest that language and literacy experiences at home have a differential impact on DLLs’ language abilities in their 2 languages. Specific components of the home environment that benefit and support DLL children’s language abilities are discussed.  相似文献

This article records and evaluates a student’s learning journey in two modules on an MA (Education) English Language Teaching (ELT) programme: an Oracy and ELT Pedagogy module and an Educational Technologies module. The notions of ‘exploratory talk’ and ‘task-based learning’ are explored using a single case study with material drawn from the student’s autobiography and diary, the spoken and written assignments, and the student and lecturers’ reflections on completion of the modules. We show, through the use of autobiography and critical reflection, what the student brings to the course and how this reflection allows him to use and transfer knowledge from one module to another. We analyse the ways in which the modules complement each other and how this influences the student’s learning and teaching practice. We then identify the key features of his learning in relation to ELT pedagogy.  相似文献

Students who are disabled are under-represented in higher education. One reason for this may be that education is not covered by the Disability Discrimination Act (1995) and disability statements to government made by individual institutions are more for information than an expression of mission or committed action. The growing empowerment of disabled people themselves has radically shifted thinking about the disabled in society and in this paper student views on provision in one large UK University are collected. Questionnaire and interview data highlight the existing shortcomings in terms of physical access but also in terms of disability awareness among those whose job it is to provide effective university education for all. The findings are broadly in line with researches elsewhere. The paper urges that further research be undertaken and that all universities urgently examine their own situation.  相似文献

On September 16, 2009, the Lambda Literary Foundation (LLF) released a statement revising their eligibility guidelines for the Lambda Literary Award, the most prestigious citation offered for LGBT books and authors. This criteria, which demands that an author must self-identify as a member of the LGBT family of writers, has been met with considerable disapproval within the field of children’s and young adult literature, with critics decrying the decision as unfair and essentialist. By arguing for the deployment of strategic essentialism as a discourse of resistance and by working to complicate discussions of essentialism within the field of children’s and young adult literature, the author of this article confronts the condemnation levied at the Lambda Literary Foundation and makes the case for the necessity of establishing the “Lammys” as an “insider-only” citation.  相似文献
