霍桑笔下的魔鬼形象--罗杰·奇灵沃思解读

通过分析罗杰·奇灵沃思心灵的发展阐述了霍桑所表达的宗教意识,认为霍桑对"善"与"恶"的评价视角是含混的,充满了矛盾的他既将"恶"的起因归咎于清教对人性的扼杀又戴着清教主义的有色眼镜,对旧的道德观表现出某种程度的认同.霍桑宗教意识的矛盾性与其家庭和社会环境影响有着密切的关系.     

海派小说的“魔性”原型

男性文本中女性常常被异化为“天使”与“妖妇”两个极端。在中国,女人祸水论是妖妇形象产生的心理基础。男性对妖妇的恐惧是男人心中的阉割焦虑使然。蝴蝶、猫、狐狸是妖女形象常见的几种喻体。动物比拟是为了表明女人所具有的恶魔力量植根于女人的天性。在施济美等女作家的文本中,男性意义世界中的“妖妇”,实际上是一个善良的“天使”。戏拟手法既拆解了男性眼光中的女性神话,又消解了男性的主体地位。     

Dancing with the devil: formative peer assessment and academic performance

Peer assessment can be important in developing active and independent learners, as well as providing more and faster feedback in large classes, compared to marking done by tutors. In addition, the evaluative, critical stance required by students in order to assess their peers' work encourages the development of higher-order cognitive skills. Changing roles from being assessed to being an assessor can also improve students' ability to judge and improve on their own work. However, peer assessment does have potential problems and there is some debate as to the appropriate academic level at which to implement it, the kinds of feedback that are given and the ways in which students respond. In addition, there is little evidence that peer assessment has an impact on academic performance. This research reports the results of an online peer assessment exercise for a macroeconomics essay conducted in a large Economics 1 class at Rhodes University. Of the 800 students, about half participated in the peer assessment exercise. Data were collected from students via a formal course evaluation. In addition, a sample of 50 essays was evaluated in terms of the relationship between peer marks and final (tutor) marks received and the impact that peer assessment had on the quality of the final essay submitted. An Ordinary Least Squares regression was used to investigate the impact of peer assessment participation on marks. Results showed that peer marks tended to ‘bunch’ in the 60–68% range, indicating the reluctance of peers to give very high or low marks. In general, peers gave more useful feedback on technical aspects, such as presentation and referencing (which were also the categories in which students most often made improvements), than on content. Regression analysis showed that peer assessment participation was not a significant determinant of final essay mark, but that economics ability and English language proficiency were.     

More clever than the devil: ujanja as schooling strategy in Tanzania

This article explores the concept of “cleverness” as it is employed by Tanzanian youth to improve their likelihood of succeeding in school. It analyzes the Swahili term ujanja, which combines cleverness, opportunism, and deception, while it also illustrates an educational anthropologist’s ongoing process of familiarization and defamiliarization with this culturally salient concept over many years of fieldwork and engagement with key participants. Specifically, the study draws on interviews with youth participating in a longitudinal study on Mount Kilimanjaro and an extended life history interview with a close friend and research assistant. The interviews reveal the strategies used by some youth to evade peer pressure, thwart sexual advances, and cultivate relationships with school sponsors. The article concludes with a call for greater use of life history methodologies in the study of complex cultural concepts like “cleverness” and of textual forms that elucidate the emotional complexity of narrator/interpreter relationships.

Imagining the shaping of reflective deliberative education leaders: The devil is in the detail

Abstract

In this article we critically engage with some of the challenges and issues pertaining to the implementation of the Advanced Certificate in Education: School Leadership following a national agreement by the national Department of Education, provincial education departments and several universities. The rather idealised vision of the programme to provide learning opportunities to promote quality education in South African schools through the development of a corps of education leaders who apply critical understanding, values, knowledge and skills to school leadership and management in line with the vision of democratic transformation seemingly meshed with our own approach to the development of leadership. However, consequent to the planning, budgeting and implementation of this school leadership programme we realised that realities posed serious challenges. In this paper we narrate how it became increasingly clear how “the devil is in the detail”.     

The devil is in the details: issues of exclusion in an inclusive educational environment

In response to federal legislation and societal views that seek to provide free and appropriate education for each child. Public schools are now opening their doors to a wide variety of learners. General-education teachers are challenged to make their classrooms more inclusive. This year-long-ethnographic study explores the experiences of 20 non-deaf and two deaf fifth-grade students, a general-education and a Resource Room teacher, and support personnel. Results highlight explicit messages of equality and inclusion that belied behaviours which marginalised and excluded the deaf students. Suggestions are made for those committed to providing all students with a fair and equitable educational experience.     

Arguing against the Special Allowance

The special schools' allowance should be abolished. Its existence, always questionable, cannot be justified at a time of growing integration, suggests Dr Denis Mongon, a teacher with 15 years' experience in special education, including six years when he received the special schools' allowance.

Kant and the struggle against evil

Abstract

Kant held that the moral vocation of the human species was to strive toward moral perfection. But in Religion within the Boundaries of Mere Reason, he at least entertained as part of the human condition a rationalist version of the Christian doctrine of original sin: that human beings have a universal, innate and inextirpable propensity to evil. Are these two Kantian doctrines inconsistent, or at least in tension with each other? If they are, the tension is a creative one. This chapter will explain the Kantian doctrine of the radical human propensity to evil and relate it to Kant's theory of the acquisition of virtue and the struggle toward moral perfection. We will see that this struggle for Kant must be social, not merely individual, and that it involves both the development of moral character and the cultivation of empirical inclinations that harmonize with morality.
