Being a Learner Using Social Media in School: The Case of Space2cre8

The aim of this article is to gain knowledge about what it means to be a learner using social media in an educational setting. The article presents an ethnographic study of students in a multiethnic community in Oslo who participate in a social networking site called Space2cre8 (S28). In this article, we set out to explore the kind of space for learning that can be created in a lower secondary classroom by a social networking site. The article provides a detailed study of how two students made use of this social networking site as part of school activities, and it outlines two specific ways in which to be a learner using social media in school. The findings suggest that a social networking site such as S28 can provide different resources for different students with different learner identities, and might represent a space in which everyday knowledge and school knowledge merge to offer a hybrid space for learning.

The inclusion of pupils perceived as having social and emotional behavioural difficulties in mainstream schools: a focus upon learning

This article focuses upon the relationship between social and emotional behavioural difficulties (SEBD) and learning. It argues that, while inclusion is desirable in principle, it can be highly problematic in practice. Further, it explores the contested nature of the concept of SEBD and the nature of support for pupils categorised as such. The article draws upon a case study which evaluates a group work approach devised by the author to support pupils experiencing SEBD within a mainstream secondary school, within a deprived area. The study (N = 69) established benchmark measures relating to pupil attendance, discipline sanctions, attainment and pupil attitudes and followed the progress of the pupils until one to two years after completion of the intervention. The findings indicate that the intervention did not reduce the differential in performance in National Tests between the Support Group pupils and comparator groups but it did impact positively upon dispositions towards learning.

思维模式对汉英表达形式的影响

在对中、英思维模式的比较研究中发现:不同的思维模式对学习者的语言表达有着极大的影响.该影响导致了句子结构、语篇结构及话语模式在这两种语言中的不同.受其哲学思想、生产方式和历史的影响,汉语呈现出一种重意义的意合法,而英语呈现出一种重形式的形合法.本文以几个实例证明此理论,并分析汉、英之不同思维模式对这两种语言的表达形式的影响.     

集体人：社会动员的行为主体

社会动员必须以动员行为主体的研究为逻辑起点,以利益为终极关怀,以理性集聚为基础的集体人设定,是对社会动员行为主体的一种尝试.作为社会动员行为主体的集体人,具有内存在性、指向性、一致性、行动可能性、反意向等特征,同时由于受权威正式与否的影响,集体人可以细分为自觉集体人和觉他集体人,这两类集体人基于自身的特征,在社会动员中发挥着各自的功效.     

SRL in Online Cooperative Learning: implications for pre-service teacher training

The aim of this article is to investigate the relation between self-regulated learning and online collaborative environments. Based on the study of a blended course for trainee teachers, it explores the potential of the online collaborative component of the course for the practice and development of Self-Regulated Learning. The study made use of two questionnaires, developed within the TELEPEERS European project, to evaluate the potential support to SRL provided by technology-enhanced learning environments. The results provide information about the aspects of SRL practised in our environment. These include social competences, such as communication and negotiation with tutors and peers, emotional and motivational aspects, such as keeping up motivation and maintaining and restoring a positive working attitude, and cognitive and metacognitive skills such as management of time and learning environment and reflection on learning outcomes. The study also suggests the need to consider not only the SRL of the individuals involved in the learning process, but also the SRL of the whole community, that is, the result of the mediation between individual autonomy and group collaboration.     

Engineering design projects as a reflection promoter

This article describes examples of reflection documented in a longitudinal research comprising two studies: a three-year three-stage study on technology project-based learning (TPBL) and a three-year two-stage study on engineering thinking (ET). Both studies used qualitative tools such as interviews, active observations, and document analysis. Reflections expressed by 10th grade pupils from eight high schools and 14 post-secondary school students who participated in the TPBL study as well as the reflection findings of experts and undergraduates from the ET study were used. The data analysis indicates that reflection is not generated on its own; it must be fostered. Reflection takes one of three forms: as a reaction to an irregularity or error made when working on the system design; conducted in groups that is inherent to the design process in industry; and from intuition that something may not be quite right, even though preliminary results seem to be correct.     

Personalized learning through 1:1 technology initiatives: implications for teachers and teaching in neoliberal times

Situated within the broader context of neoliberalism, this article explores how personalized learning, as tied to 1:1 technology initiatives, prompts changes in teachers’ classrooms and practices. The article draws upon a case study of one novice teacher as a way to view how personalized learning is undergirded by tenets of neoliberalism that ultimately change the relationship between teachers, students, and knowledge. While this article does not dispute the positive effects that personalized learning through technology has offered to many students, it explores facets of how such a change has reoriented the role of the teacher and repositioned knowledge as it relates to classrooms and students.

Teaching methods and student personality — The search for an elusive interaction

Decades of research at the tertiary level have produced the finding that the use of different teaching methods makes no difference to student learning when end-of-course examination performance is accepted as the criterion of such learning. This conclusion has been based on a comparison between the average mark gained by groups of subjects taught in different ways. The present article takes the position that the use of such mean scores serves to conceal individual variability, and hypothesizes that it is possible to identify personality characteristics likely to predispose a student to perform better under one teaching approach rather than another. A programmatic series of studies using two approaches to personality measurement, purpose-concealed and face-valid, and two instructional approaches, lecturing and independent study, is described culminating in the conclusion that the student likely to perform better under the latter teaching method sees himself as being more tense and anxious than the student likely to perform better under the former method.Flinders University of South Australia     

Environmental education,national curriculum and primary school teachers. Findings of a research study in England and possible implications upon education for sustainable development

This article reports the results of a research study on the impact of environmental education (EE) upon English primary school teachers, and it then discusses the findings of the study in relation to education for sustainable development, as EE is considered one of the two precursors of education for sustainable development. The article begins by considering the development of EE in the English national curriculum of primary schools and then briefly outlines and reports two major findings of the study, comparing them against the new context of education for sustainable development. Overall, the article demonstrates how EE, the national curriculum and teachers have interacted with each other, while arguing that there seems to be a parallel course among education for sustainable development and EE in the national curriculum, with no apparent crossroad to link the two and explain how education for sustainable development is partly based on EE as well.

Lecturers’ and students’ perceptions of the role and value of the residential school at the University of Zambia

The residential school, held once a year, usually for two weeks, is an integral and compulsory component of distance education at the University of Zambia. It is, however, expensive for students and can discourage prospective students from applying for distance learning courses. This notwithstanding, residential schools have advantages. This article summarizes the findings of a study in a Zambian setting in which both lecturers and students felt that the residential schools have important educational benefits, such as, enabling lecturers to discuss difficult issues with and providing direct academic guidance to students. The paper does not discuss, in depth, why difficult issues arise, nor does it argue that direct academic guidance is essential. The arguments against residential schools perhaps need to be pursued more vigorously, such as, the barrier to entry for those unable to attend.

A folkloristic approach to understanding teachers as storytellers

This article presents a folkloristic analysis of two history teachers' performances of lectures in an eleventh-grade American history course. Folklore is defined as the situated performance of a traditionalized text (in this case, from the course textbook) in which the performer (the teacher) takes responsibility for communicating a version of the text to the audience (the students) that is meaningful to them in their current situation. Using performance analysis grounded in folkloristic theory, it is shown that the history lecture is a complex genre combining such simple genres as anecdote and personal experience story. In so doing, a folkloristic approach to the study of teachers as storytellers is explained.     

对语文学科“复合性”的再认识

语文教育界基本认同语文学科存在"复合性",但它是哪些因素之间的复合,却值得讨论。汉语、文学分科教学之失败的历史,汉语、文学、文章教学的实然、应然的关系表明:语文学科不是汉语教学与文学教学二者的简单复合,而是语言、文学、文章教学三者的复杂复合。
