Subjects were five Cambodian mother‐child pairs. Three mothers (Group One) had received one year's schooling, and two (Group Two) had had no schooling in Cambodia; all children were participating in regular primary school class reading programs and receiving individual help from an ESL teacher. Group One was introduced to Shared Reading in a multiple baseline across‐subjects design, while an AB design was used for Group Two. Probes were taken of mothers and children reading individually from unseen books at the same level as those used in Shared Reading. During the Shared Reading program the Group One mothers and children markedly increased their rate of progress through book levels as did the Group Two children, but the Group Two mothers did not, although there was some evidence of minor progress in word recognition. Results are discussed in terms of the importance of the interactive social context for acquiring literacy skills.  相似文献

In this paper we discuss the background to this study in the development of the international MSc e‐Learning Multimedia and Consultancy. The aims of the study focus on the conditions for achieving communication, interaction and collaboration in open and flexible e‐learning environments. We present our theoretical framework that has informed the design of programme as a whole which is based on a socio‐constructivist perspective on learning. Our research is placed within an action research framework and we outline our position within the critical or emancipatory tradition and also our standpoint on the use of ICT in education. We discuss the design of the programme and also our pedagogical approach and describe in detail the particular context for this study. We report on the student experience of being learners on this module, their perceptions of what they have gained most from learning from and with each other and their responses to the various ways in which ‘scaffolding’ has been designed and implemented by the tutors. Finally we offer some reflections on the conditions for achieving well‐orchestrated interdependence in open and flexible e‐learning environments.  相似文献

One major world view that dominates the field of developmental psychology is the organismic world view. This world view depicts individuals, including children, as active agents who know the world in terms of their own operations upon it. Individuals are seen as being in control of their own learning. This control is exercised by individuals initiating and maintaining their own learning opportunities within a responsive social context.

The responsive social context is increasingly seen by developmental psychologists (Bronfenbrenner, 1979; Wood, 1982) as of fundamental importance for the acquisition of intellectual skills. It is within responsive social contexts that individuals acquire not only specific skills but also generic knowledge about how to learn. It is this generic knowledge that allows individuals a measure of control over, and hence independence in, these social contexts.

Educational policy statements, school prospectuses and, more recently, the Core Curriculum, abound with aims and objectives to do with achieving individual autonomy and independence as a learner. Yet there is growing evidence that in many contemporary classrooms at primary, secondary and tertiary levels, we may be providing precisely the wrong contexts for students to become autonomous and independent learners. Too many classroom learning environments simply do not qualify as responsive social contexts. Individual learners have minimal control over learning interactions and hence are excessively dependent on external control by teachers.

Theoretical explanations for differences between unskilled and skilled performance are being sought increasingly in terms of characteristics of the specific contexts in which performance occurs and less in terms of qualitative differences in global capacities or in thinking processes between individuals (Wood, 1982). For example, differences in complexity of oral language between three‐year‐old children might be explained by differences in the amount and quality of language exchange with caregivers. They might also be explained by differences in caregiver skills in interpreting and responding to needs signalled by an individual child's use of language in a particular context. If we are genuinely concerned about aims of autonomy and independence in learning, then we need to discover and analyse those characteristics of responsive environments which support and promote independent learning. On the basis of existing research it is possible to specify four such characteristics of responsive learning contexts.

This paper documents the creation, implementation and analysis of a survey instrument designed to reveal patterns of use and attitudes towards the value of social media by UK teachers. The study was motivated to discover which teachers use social media professionally, how they use it (both personally and professionally) and attitudes to social media as a professional tool (for their students' and their own professional use). The instrument was created from verbal data from two focus group discussions regarding the use of social media in education. Attitude statements were included verbatim when practical. This instrument was placed online and practising teachers invited to complete it (n?=?216). Exploratory factor analysis and hierarchical clustering identified 9 factors from 54 attitude statements and 5 distinct teacher groups. The rich data allowed each group to be carefully defined, providing potentially invaluable information to school leaders when developing social media projects to recognize and accommodate the full range of teacher concerns and experience. The paper also addresses methodological concerns regarding instrument creation, dealing with missing data and the impact of missing data on subsequent analysis.  相似文献

The Trends in International Mathematics and Science Study (TIMSS) is a comparative assessment of the achievement of students in many countries. In the present study, a rigorous independent evaluation was conducted of a representative sample of TIMSS science test items because item quality influences the validity of the scores used to inform educational policy in those countries. The items had been administered internationally to 16,009 students in their eighth year of formal schooling. The evaluation had three components. First, the Rasch model, which emphasizes high quality items, was used to evaluate the items psychometrically. Second, readability and vocabulary analyses were used to evaluate the wording of the items to ensure they were comprehensible to the students. And third, item development guidelines were used by a focus group of science teachers to evaluate the items in light of the TIMSS assessment framework, which specified the format, content, and cognitive domains of the items. The evaluation components indicated that the majority of the items were of high quality, thereby contributing to the validity of TIMSS scores. These items had good psychometric characteristics, readability, vocabulary, and compliance with the assessment framework. Overall, the items tended to be difficult: constructed response items assessing reasoning or application were the most difficult, and multiple choice items assessing knowledge or application were less difficult. The teachers revised some of the sampled items to improve their clarity of content, conciseness of wording, and fit with format specifications. For TIMSS, the findings imply that some of the non‐sampled items may need revision, too. For researchers and teachers, the findings imply that the TIMSS science items and the Rasch model are valuable resources for assessing the achievement of students. © 2012 Wiley Periodicals, Inc.

This paper raises some questions about academic authorial honesty under the headings of Plagiarism (including self‐plagiarism), Theft, and Collusion. Compared with the medical sciences, the social sciences in general and education specifically, lag behind in terms of critical attention being paid to the problem of plagiarism, the peer review process and academic authorial ethics. The ubiquity of the Internet, the ever intensifying demand to publish or perish, and maybe, a general shift in perceptions of what constitutes ‘bad’ plagiarism and collusion which challenge traditional notions of what constitutes authorial honesty, mean that the time may be ripe for a consideration by academic writers and journal editors of how they regard and deal with the whole area. This paper makes an early contribution to the discussion.  相似文献
