This article is the third in a series reporting on the changes in attitudes and interests‐‐mainly with respect to physics‐of several hundred students as they proceed through the Danish upper secondary school (Gymnasium). It concentrates on the results of the final investigation which took place shortly before the students leave the school. 相似文献

AbstractMinority-serving institutions are important in the production of teachers of color. However, this formative process is not without limitations. This multisite, multistate study relied on network analysis techniques to unveil timely and relevant concerns that students, faculty, and administrators identified as critical toward the strengthening of teacher production. 相似文献

This study examined pre-service primary teachers' perspectives on teaching and learning experiences within college-based courses in ‘practical’ subject areas within a teacher education programme. Following three individual lectures (one each in art, music and physical education), pre-service teachers (n=11) participated in focus group interviews sharing their perspectives on the teaching and learning experiences. These data were analysed thematically and supported by teacher educators' (n=3) planning and reflection documentation. Although the problematic nature of the ‘practical’ suggests appeal and peril of the ‘practical’, the important nature of negotiating the ‘practical’ to enhance student learning is apparent. Students emphasised the value of practical engagement and expressed a strong preference for working in groups to create a safe learning environment to develop confidence and competence. These insights suggest key aspects of a pedagogy of teacher education in these ‘practical’ areas. The importance of being aware of and, in some cases, challenging student perspectives on how they learn best in these curricular areas is discussed. 相似文献
