We have undertaken a critical appraisal of the current English system of law regulating: (1) Provision of services designed to prevent children coming into care of local authorities, which are the authorised agencies for dealing with children who are abused or neglected. (2) Ways of receiving children into care and also ways of terminating care orders. We question whether, and under what circumstances, care orders are really necessary. (3) Periodic reviews of children in care. We are critical of the English system and look to models in the USA as guides towards the possible reform of English law. We take the same perspective when considering termination of parental rights. In our opinion good laws do not of themselves provide the care and love which a child requires, but they make the caring possible by loved and loving adults. We argue that the law must provide the best possible framework to allow adequate caring by members of the non-legal professions, such as social workers and foster parents. At the same time the law must ensure that the rights of parents and children are protected. 相似文献

This study aimed at investigating the relationship between intellectual, social, personal and personality variables of academically gifted secondary school students. A total of 297 tenth grade boys and girls were identified on the basis of three main criteria: 1. Academic achievement with special emphasis on Arabic language, science and math scores; 2. Behavioural traits; 3. General mental ability and general adjustment. Data related to socioeconomic status and personal characteristics were also collected. Results of the analysis of variance showed that there were significant differences between gifted and nongifted groups in general mental ability, achievement, general adjustment, behavioural traits, personal and social variables, in favour of the former. 相似文献

Previous work suggests that standard dialects assume their prestige over other language varieties not because they are linguistically or aesthetically superior, but because of historical, cultural norms. An empirical investigation lends this view support by showing that British listeners cannot differentiate evaluatively speech styles having distinct social meanings in Greece. 相似文献

Abstract This paper reports the results of a study to understand why some New Zealand dairy farmers are changing from twice-a-day (TAD) to once-a-day (OAD) milking. Increasing herd size, unavailability of suitable labour and changing lifestyle expectations from farmers and their staff have led some to explore OAD milking as a means of alleviating these issues. A convergent interviewing process was used with 21 dairy farmers who had all adopted OAD milking. A marketing approach, based on consumer behaviour theory and farming systems theory, was used to classify farmers into segments based on their different reasons for adoption. Six segments were identified, viz., herd expansion, time needed to build capital, decreasing labour, increasing labour flexibility, feed shortfalls, and herd health, motivating farmers to adopt OAD milking. Farmers in some segments such as herd expansion and feed shortfalls indicated that they were less likely to be long-term adopters than those in the other segments. Farmers interviewed unanimously understood that OAD milking led to reduced milk yield but were generally prepared to tolerate this to achieve their short-term or long-term goals. 相似文献

Abstract This article describes the use of two linked instruments, the Instructor Effectiveness Check Sheet (IEC) and Instructor Effectiveness Questionnaire (IEQ). The use of an evaluation instrument during a course can enable improvements to be made — even with experienced instructors. Detail can be taken from the IEC and IEQ to find obvious and not so obvious needed changes and attention to individuals in the group. The article gives an example where the instruments were used to teach instructors about different pedagogical constructs, describes further research using the instruments at the Nantahala Outdoor Center, USA, and describes a case study on a wilderness education group that illustrated improvement in effective teaching. 相似文献

Multiple-choice (MC) reading comprehension test items comprise three components: text passage, questions about the text, and MC answers. The construct validity of this format has been repeatedly criticized. In three between-subjects experiments, fourth graders (N 1 = 230, N 2 = 340, N 3 = 194) worked on three versions of MC items from the Progress in International Reading Literacy Study 2001 reading comprehension test with relevant components successively deleted: “original version” (text, questions, MC-answers), “version without text” (questions, MC-answers), “version without text and without questions” (only MC-answers). Answering correctly the MC items became more difficult as the relevant information was eliminated. In the two narrative fictional texts presented, the students' performance of the version without text was not better than chance. Conversely in the informational (fictional) text, the students' performance of the version without text was better than chance. In the third condition, students' performance was never better than chance. 相似文献

In science education in the Netherlands new, context‐based, curricula are being developed. As in any innovation, the outcome will largely depend on the teachers who design and implement lessons. Central to the study presented here is the idea that teachers, when designing lessons, use rules‐of‐thumb: notions of what a lesson should look like if certain classroom outcomes are to be reached. Our study aimed at (1) identifying the rules‐of‐thumb biology teachers use when designing context‐based lessons for their own classroom practice, and (2) assessing how these personal rules‐of‐thumb relate to formal innovative goals and lesson characteristics. Six biology teachers with varying backgrounds designed and implemented a lesson or series of lessons for their own practice, while thinking aloud. We interviewed the teachers and observed their lessons. Our results suggest that rules‐of‐thumb, which differed substantially among the teachers, indeed to a great extent guide the decisions teachers make when designing (innovative) lessons. These rules‐of‐thumb were often strongly associated with intended lesson outcomes. Also, teachers’ personal rules‐of‐thumb were more powerful in determining the lesson design than formal innovative goals and lesson characteristics. The results of this study encourage more research into how rules‐of‐thumb reflect teachers’ practical knowledge, for which suggestions are made. 相似文献

ABSTRACT This paper reports a survey of lecturers from six Turkish teacher education institutions. The study specifically aimed to investigate the fundamental issues, concerns, and challenges of implementing information technology (IT) in teacher education. The survey consisted of four sections. The first section of the survey comprised several aspects of IT familiarity, namely the use of twelve common IT applications. The second section investigated benefits of IT to lecturers and teachers seeking to reveal how teacher educators view the role of new instructional technologies for teaching and learning. The third section dealt with the factors which are vital to implementing IT in teacher education, and the final part drew attention to the issues affecting employment and retainment of competent lecturers in teacher education. Most lecturers had a rather positive image and enthusiasm towards the use of IT in teacher training, despite a lack of experience. Recommendations are made for future strategies in Turkey on the basis of this survey and the associated literature. 相似文献
