The dialogue that occurs in science classrooms has been the subject of research for many decades. Most studies have focused on the actual discourse that occurs and the role of the teacher in guiding the discourse. This case study explored the neglected perspective of secondary science students and their beliefs about their role in class discussions. The study participants (N?=?45) were students in one of the three differentially tracked chemistry classes taught by the same teacher. Findings about the differences that exist among students from different academic tracks are reported. While it seems that epistemological beliefs focusing on content are common for the students in this study, the students' social framing in the different tracks is important to consider when teachers attempt to transition to more dialogic forms of discourse. Some key findings of this study are (a) students’ beliefs that science is a body of facts to be learned influenced the factors they deemed important for whole-class discussion, (b) students from the lower-level track who typically were associated with lower socioeconomic status were more likely to view their role as passive, and (c) students’ comfort level with the members of the class seemed to influence their decisions to participate in class discussions. 相似文献
High- and low-IQ children in the first, third, and fifth grades performed two free-recall tasks: a sort-recall task with sets of categorically related pictures, and a class-recall task, with children recalling the current members of their school class. All children were deemed to be experts concerning the composition of their school class, but, unlike experts in other domains, had no special motivation associated with their expertise. Recall and clustering on both tasks were high. The high-IQ children performed better than low-IQ children only on the sort-recall task. IQ was significantly correlated with measures of performance on the sort-recall task but not on the class-recall task. The results reflect the fact that the memory benefits associated with being an expert (here, elimination of IQ effects) are related to the greater knowledge the expert possesses and not to factors of motivation. 相似文献
Post‐Fordism and globalisation are trends in the contemporary world in which the role of the market and consumer are given greater centrality. It has been argued that these trends have consequences of spreading ‘Western’ lifestyles and values around the globe, encouraging cultural uniformity, while also giving greater importance to senses of the local and place, encouraging cultural difference. Drawing on Foucault's notion of discourse, this paper suggests these trends are found also in changing theories of distance education and open learning. It is argued that notions of distance education are part of the trend towards uniformity under conditions of globalisation, while those of open learning are part of the trend encouraging difference and diversity. The discussion is situated within contemporary debates about the modern and postmodern. 相似文献
The Institute of Education is the only institution in Singapore that trains and prepares individuals for the task of teaching. In order to ensure that its products, the teachers, are of a respectable calibre, not only should the training programme be reviewed regularly, but also the method of selecting trainees. 相似文献
Students with learning disabilities (LD) represent a vulnerable population and are at higher risk for social and emotional challenges compared to their peers without LD. A strengths‐based orientation is recommended to encourage building resilience factors to counteract the negative effects of LD over the lifespan. To identify areas of strength and areas for growth, measurement tools that are appropriate for the population of students with LD are needed. This study examined the psychometric properties of the Social Emotional Health Survey—Secondary for use with students with LD. Data from students in three secondary schools (n = 2,847) were used to confirm the factor structure, establish measurement invariance, and compare the social–emotional profiles of students with and without LD. The LD group was found to report lower overall social–emotional strengths than those of their non‐LD peers. Implications for practitioners and researchers are discussed. 相似文献
Teachers are central to providing high-quality science learning experiences called for in recent reform efforts, as their understanding of science impacts both what they teach and how they teach it. Yet, most elementary teachers do not enter the profession with a particular interest in science or expertise in science teaching. Research also indicates elementary schools present unique barriers that may inhibit science teaching. This case study utilizes the framework of identity to explore how one elementary classroom teacher’s understandings of herself as a science specialist were shaped by the bilingual elementary school context as she planned for and provided reform-based science instruction. Utilizing Gee’s (2000) sociocultural framework, identity was defined as consisting of four interrelated dimensions that served as analytic frames for examining how this teacher understood her new role through social positioning within her school. Findings describe the ways in which this teacher’s identity as a science teacher was influenced by the school context. The case study reveals two important implications for teacher identity. First, collaboration for science teaching is essential for elementary teachers to change their practice. It can be challenging for teachers to form an identity as a science teacher in isolation. In addition, elementary teachers new to science teaching negotiate their emerging science practice with their prior experiences and the school context. For example, in the context of a bilingual school, this teacher adapted the reform-based science curriculum to better meet the unique linguistic needs of her students.
We study the effects of homeschool background and time use on academic performance among students at Patrick Henry College, a private religious institution with a 63-credit core classical liberal arts curriculum. Using ordinary least squares regression analysis, we examine four research questions: (1) Does time use influence academic performance? (2) Do homeschooled students perform differently than traditionally schooled students? (3) Does parental education moderate the impact of homeschooling on academic performance? (4) Does homeschooling moderate the impact of ACT scores on academic performance? 相似文献
Since the 1970s there has been a steady growth in the use of preschool home visiting schemes by a diversity of statutory and voluntary agencies, working with families (commonly mothers and their children) who are either themselves labelled disadvantaged or live in areas which have been termed ones of multiple disadvantage. The schemes appear to have followed individual patterns. However, it will be argued that there are two themes common to them all: ‘education for prevention’ and ‘participation’. This paper seeks to critically examine these themes in the light of their concentration upon working‐class mothers, and to consider, through a case study of one such scheme, the perspectives of the mothers receiving the services. 相似文献
