Teachers are digikids too: the digital histories and digital lives of young teachers in English primary schools

In this article I consider the digital lives of a number of young teachers. Some are confident, competent movers in digital worlds, some are not. I wonder why, and look back at the teachers' digital histories to see whether ways in which they learned about digital worlds affects their lives now. I identify three different routes to learning about digital worlds, and describe these with representative stories. Two are serious solitary journeys, one self‐taught the other school‐taught. Most teachers in these groups use digital technologies for work and for the business of life. The third route is playful social. Teachers in this group have experienced learning about digital worlds with fellow enthusiasts and in playful contexts. These teachers use digital technologies for pleasure as well as the business of life and work. I argue that it is important that young teachers and student teachers be given time on courses to think about and discuss their own digital literacy histories.     

关于《汉语拼音方案》中y、w性质的界定

《汉语拼音方案》对y、w的性质又未作具体的界定，致使人们对y、w这两个字母的理解较为混乱．这是《汉语拼音方案》的一大缺陷。为了解决这一“缺陷”性问题，应该对《汉语拼音方案》中y、w的性质作具体的界定，以让《汉语拼音方案》在汉语语音发展以及推广普通话的过程中进一步发挥作用。     

Vertical Upheaval Buckling of Submarine Buried Heated Pipelines with Initial Imperfection

In this paper,a theoretical solution of vertical buckling is proposed with regard to the typical initial imperfection cases of submarine pipelines.Analytical tools are applied to predicting the occurrence and consequence of inservice buckling of a buried heated pipeline in Bohai Gulf.An evaluation is performed to ensure the pipeline structural integrity during operation under loading conditions.Different protection measures are proposed and their validities are analyzed.Analyses show that for the same magnitude of initial imperfection,the upheaval buckling of pipeline with isolated prop model is the most likely to occur.The empathetic model represents a special sub-case of continuous prop model,and the calculated buckle temperature is between the first stage and the second stage of post-upheaval buckling of continuous prop model.And the larger the initial imperfection,the less the axial force required for the upheaval buckling.Meanwhile,it can be seen that a peak point appears on the curves of temperature difference against buckling amplitude for small initial imperfection.Besides,trenching-burial is one kind of protection measures preventing the pipeline from thermal upheaval.The covered depth-to-diameter ratio depends on the design conditions and subsoil properties.For the given pipeline in this paper,the covered depth-to-diameter ratio is recommended to be 5.     

新课程标准下对中学语文教学人文情怀缺失的反思

在新课程标准全面实施,大力提倡素质教育的今天,仍然有不少中学语文教师在教学中只注意其工具性,而忽视对学生人文情怀的培养,究其主要原因是中学语文受应试教育的影响,使得教学重心仍有较大的偏离;教师的教学缺乏创新;校园周边文化缺乏正确的导向作用等。为改变当前中学语文教学学生人文情怀缺失的现象,应采取改革语文考试的内容,提高语文教师的人文意识,注重引导学生较系统地继承经典文化,有针对性地传承民间、乡土文化,对学生进行美育和艺术教育等多项对策,以培养为社会所需要的、具有人文情怀的高素质人才。     

The tensions of preparing pre-service teachers to be assessment capable and profession-ready

There is both a growing appreciation of teacher assessment capability for the improvement of school student learning and achievement and a commensurate drive for graduates in Australian Initial Teacher Education institutions to demonstrate impact on school student learning as part of a national accreditation process. We argue in this article that if institutions are to prepare assessment capable graduates who are “profession-ready”, attention to practice architectures is warranted. Practice architectures are the features in schools that enable and/or constrain practice. Skills, knowledge and understandings do not just cleanly transfer across Initial Teacher Education institutions and practicum contexts into graduate teacher classrooms. Practitioner identities are produced through “relatings” within specific social-political arrangement, “doings” that constitute activities afforded in material-economic conditions, and “sayings” that are a dominating medium in cultural-discursive frameworks.

Psychometry of the Teacher's Sense of Efficacy Scale in Spanish Teachers' Education

Our objective was to test the factorial validity of the different versions (TSES-24, TSES-12, and TSES-11) of the Teacher's Sense of Efficacy Scale in Spanish preservice teachers'. The participants were 358 preservice teachers. The confirmatory factor analysis showed inadequate fit indexes for both TSES-24 and TSES-12 but adequate fit indexes for TSES-11, which was invariant across gender. The reliability analysis showed appropriate values. The global factor for teachers' sense of efficacy and the three factors that constitute it positively predicted intrinsic motivation and life satisfaction. The global factor for sense of efficacy and the classroom management and student engagement factor negatively predicted amotivation. The results support the use of the TSES-11 three-factor model, rather than TSES-24 or TSES-12, for Spanish preservice teachers.     

Preparing new teachers for inclusive schools and classrooms

The policy of including pupils with special educational needs (SEN) in mainstream schools and classes is now firmly established in many jurisdictions worldwide. Successful implementation of such policy depends largely on teachers having the knowledge, skills and competencies necessary to make it work. This poses a considerable challenge for both teachers and those responsible for Initial Teacher Education (ITE). This article presents the results of a study investigating current Northern Ireland practitioners' perceptions of their initial ITE relative to SEN. The major question under investigation was whether they felt that their ITE prepared them to be effective teachers in inclusive settings. Findings confirm research in other jurisdictions that teachers feel unprepared for inclusion. Emerging from this are the participants' recommendations for the content and delivery of SEN courses in ITE. Their recommended model of SEN delivery is a combination of ‘permeation’ plus a ‘stand alone’ course with the focus on student characteristics, behaviour management, assessment and evaluation, and SEN legislation.
