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 aim of this study was to appraise whether different forms of the SA T used since the mid-1970s varied in their correlations with academic performance criteria in the same cohort of examinees. A 1975 form and a 1985 form were administered to two random samples of high school juniors, and self-reported grade point average and high school rank were obtained. The SAT-Verbal and SAT-Mathematical scores generally had similar correlations with the grade criteria in the two samples. The principal conclusion is that the 1975 form of the SAT does not have greater validity than the 1985 form in assessing academic performance, at least at the high school level. This outcome offers no support for the hypothesis that the decline in the SAT's ability to predict college grades since the mid-1970s, observed in recent research, is attributable to changes in the test.  相似文献

Employers optimally pursue activities which facilitate the coordinating of employee characteristics and the requirements of the job. One allegedly important employee characteristic is the level of education. Employees with higher levels of education are rewarded with higher wages than employees with lower levels. This may occur if higher levels of education make an employee truly more productive or if because of an employer's beliefs only those individuals with higher levels of education are allowed to enter the higher paying positions (occupational screening).The above propositions are testable, depending crucially upon the theoretical model employed for determining occupational choices. We shall compare the implications of two possible occupation choice models: (1) enter the job which offers the highest lifetime income, (2) enter the job which offers the highest level of overall satisfaction. We estimate these two models using the NBER-TH data sample. By distributing our estimated results and the actual distribution of occupations over the education levels of high school, some college and BA we can see if more or less people are expected to enter specific occupations at each education level. Support for screening exists if more people are expected in high status occupations at low education levels than are actually in those occupations.When comparing the estimated results for each model we see different outcomes emerge. The latter indicates that screening does not exist while the former does. We present arguments as to why we feel that the second model is the more correct and appropriate and, consequently, why we feel that education is not an effective screening device.  相似文献

A visitor to a new country is assaulted by many changes, both environmental and cultural. Expecting things to be different the visitor is shocked by what he/she finds, thus the term culture shock. A second shock, possibly more traumatic, awaits the international sojourner upon his or her arrival home. The experiences of the returnee typically do not match his or her expectations. Frequently, the individual returning home is not anticipating adjustment difficulties. Compounding the problem is the fact that re-entry has not been widely recognized or researched and thus, little has been done to help individuals to prepare for it.Focusing on international students, who by definition return home, this paper refers to a wide range of social, cultural, political, educational and professional difficulties. The many variables which determine the extent of re-entry shock are identified and discussed. A group program is suggested as one strategy for assisting those about to return home. The results of a pilot study of such a program illustrate how it can be a powerful force to minimize the disorientation and shock of re-entry.This paper serves as a challenge to all those who are responsible or work with international students. Re-entry preparation is also a prerequisite if individuals, institutions, corporations, home countries and host countries are to maximize the benefits and minimize the problems of studying or working abroad.  相似文献

Students who engage in challenging behaviour compromise the fundamental ability of schools to educate children. Consequently, teachers face the daunting task of designing effective strategies to promote positive educational outcomes for their students. Since the 1997 Individuals with Disabilities Education Act amendments, the use of positive behaviour supports (PBS) to address the behavioural needs of children challenged by disabilities has expanded. There is evidence to support the utility of PBS in reducing challenging behaviour among students. However, successful schools are also gauged by the academic achievement of their students. Hence, it is important to examine the extent to which behavioural outcomes are related to academic outcomes. The purpose of this paper is to examine the extent to which PBS interventions aimed at reducing challenging behaviour result in corresponding improvement in academic achievement. A meta‐analysis of extant research indicated a positive correlation of 0.40 between improvement in problem behaviour and academic achievement.
