The problem of student indiscipline is an issue of concern for teachers and parents around the world. Teachers need to maintain student discipline and for them to do so it is important that they also understand the nature of discipline problems. This study, by Lawrence Kofi Ametepee, who is studying for a PhD in special education, Morgan Chitiyo, board certified behaviour analyst and Assistant Professor of Special Education, both at Southern Illinois University, Carbondale, USA, and Susan Abu, who is currently a graduate student in the Department of Women's Studies at Texas Women's University, was designed to examine the nature and perceived causes of student indiscipline in Zimbabwean secondary schools. The authors anticipate that such an examination will promote teachers’, parents’ and policy makers’ understanding of student indiscipline, which will, in turn, enhance disciplinary policies and practices, making schools safer for all students and more effective in their role as educational and socialising agents. 相似文献

The article sets off with a brief summary of the history of appraisal and disposal of records as processed at the National Archives of Iceland (NAI) since its establishment in 1882 to present times. Rules on appraisal and disposal of records introduced in 1900, 1911, and 1916 were ignored and all records were kept. Status quo remained until 1985 when a new National Archives Act was passed. The appraisal and disposal process adopted then is described and explained. It included the publication of instructions on records management as well as forms relating to records management. The influence of acts of law on the appraisal and disposal process is explained. Finally the experience with the arrangement of organised appraisal in Iceland is described. 相似文献
