The importance of vocational teachers’ professional identification for what they regard as important knowledge in the Building and construction programme]

This study examines the importance of vocational teachers’ professional identification for what they regard as important knowledge in the Building and construction programme in Swedish upper secondary school. The analysis is based on responses to a questionnaire completed by a large majority of teachers in the Building and construction programme in the Västra Götaland region. The responses suggest that the professional identification is an important factor not only for vocational teacher’s identification of important knowledge for students, but even more so for what they value as important knowledge in their own role as teachers. Two different types of vocational teachers emerge from the analysis: one who sees one’s self primarily as a craftsman and another who sees one’s self primarily as a teacher. While both types of vocational teachers place great importance on knowledge that can be traced back to a vocational culture, the ’craftsman’ clearly considers such knowledge as more important than, and more isolated from, pedagogical issues and knowledge stemming from a school culture. In contrast, the ’teacher’ considers the three fields as being almost equally important and regards vocational culture as more closely associated with pedagogical issues and a school culture

Inter- and Intrasite Correlations of Large-Scale Parameters from Macrocellular Measurements at 1800 MHz

The inter- and intrasite correlation properties of shadow fading and power-weighted angle spread at both the mobile station and the base station are studied utilizing narrowband multisite MIMO measurements in the 1800 MHz band. The influence of the distance between two base stations on the correlation is studied in an urban environment. Measurements have been conducted for two different situations: widely separated as well as closely located base stations. Novel results regarding the correlation of the power-weighted angle spread between base station sites with different separations are presented. Furthermore, the measurements and analysis presented herein confirm the autocorrelation and cross-correlation properties of the shadow fading and the angle spread that have been observed in previous studies
