    This research is a case study of using a distance learning network for teachers’ professional development in Egypt. It aims to investigate the impact of using Egypt’s National Network for Distance Training (NNDT) in developing teachers’ knowledge and on building communities of practice. It explores the role of professional development experts and teachers’ participation within the network. In addition, it draws attention to the teachers’ level of engagement in professional development programmes and, therefore, it reveals their modes of participation within the network. Moreover, it identifies the role of the technology in facilitating communication and collaboration between participants. Finally, this paper offers a number of recommendations that aim to develop the network capabilities to become a more ‘effective’ means for teachers’ professional development in Egypt

    Developing professional knowledge during initial design and technology teacher education

    This article seeks to identify the components which make up teachers' professional knowledge:subject content knowledgepedagogical content knowledgecurricular knowledgeschool subject knowledge";I don't think anything quite prepares you for teaching in a class does it?"; (ITT technology student).The greater involvement of schools in theprofessional development of new teachers makes it increasingly important to establish a common framework of understanding between students, school staff and lecturers in higher education. This understanding naturally covers common expectations of subject teaching competences to enter the profession, such as those pUblished by DATA (1995). School-Higher Education Institute (HEI) partnerships have existed for years, but an increased use of subject 'mentoring' in initial teacher education means it is useful also to extend our common understanding to a fuller discussion of the different components which make up teacher professional knowledge. Staff at the Centre for Research into Teacher Education (CRETE) at the Open University are working to develop such a framework of teacher professional knowledge and are researching how aspects of such knowledge (or the lack of them!) impact on school teacher performance. More research needs to be done, but I suggest here some preliminary ideas of a framework which could help discussion and lead to shared language amongst the different 'players'; students, school-based mentors and HEI tutors

    Approaches and models in technology teacher education: an overview

    In this paper, I give an overview of the different models and approaches to technology teacher education. Many of the issues which shape the requirements for the professional development of teachers are common to the different teacher education structures which exist, and the need to improve the quality and quantity of technology teachers is shared by all countries. By standing apart from any one country's programme, perhaps novel solutions to common problems will present themselves. I present here a framework for analysis which may be applied to a range of courses, both pre-service and INSET, and consider both new and traditional approaches to the education of technology teachers

    Total hemispherical emittance measured at high temperatures by the calorimetric method

    A calorimetric vacuum emissometer (CVE) capable of measuring total hemispherical emittance of surfaces at elevated temperatures was designed, built, and tested. Several materials with a wide range of emittances were measured in the CVE between 773 to 923 K. These results were compared to values calculated from spectral emittance curves measured in a room temperature Hohlraum reflectometer and in an open-air elevated temperature emissometer. The results differed by as much as 0.2 for some materials but were in closer agreement for the more highly-emitting, diffuse-reflecting samples. The differences were attributed to temperature, atmospheric, and directional effects, and errors in the Hohlraum and emissometer measurements (plus or minus 5 percent). The probable error of the CVE measurements was typically less than 1 percent
