The scientific competencies advocated by the Programme for International Student Assessment (PISA) focus on the abilities needed in students' adult lives. This study investigated how such scientific competencies could be improved by using online argumentation. One hundred and thirty-eight 8th grade high school students took part in the study, with 69 in the experimental group and 69 in the control group. A quasi-experimental design was adopted and qualitative and quantitative analyses were used. An online argumentation system served as an aid for argumentation instruction and activities among experimental group students during the experiment. The results showed that using online argumentation could improve the students' scores for the PISA scientific competencies. The experimental group students outperformed their counterparts in terms of overall mean scores for the scientific competencies. On the one hand, the individual competencies of ‘using scientific evidence’ and ‘identifying scientific issues’ of the experimental group were higher than those of the control group. On the other hand, the experimental group students did not outperform their counterparts in terms of competency in ‘explaining phenomena scientifically’. Using an online environment to complement argumentation instruction and organizing argumentation activities focused on related topics may be a potential direction to consider for improving students’ PISA scientific competencies. 相似文献

OBJECTIVE: The aim of this paper is to examine some of the factors that facilitate and hinder interagency collaboration between child protection services and mental health services in cases where there is a parent with a mental illness and there are protection concerns for the child(ren). The paper reports on agency practices, worker attitudes and experiences, and barriers to effective collaboration. METHOD: A self-administered, cross-sectional survey was developed and distributed via direct mail or via line supervisors to workers in statutory child protection services, adult mental health services, child and youth mental health services, and Suspected Child Abuse and Neglect (SCAN) Teams. There were 232 completed questionnaires returned, with an overall response rate of 21%. Thirty-eight percent of respondents were statutory child protection workers, 39% were adult mental health workers, 16% were child and youth mental health workers, and 4% were SCAN Team medical officers (with 3% missing data). RESULTS: Analysis revealed that workers were engaging in a moderate amount of interagency contact, but that they were unhappy with the support provided by their agency. Principle components analysis and multivariate analysis of variance (MANOVA) on items assessing attitudes toward other workers identified four factors, which differed in rates of endorsement: inadequate training, positive regard for child protection workers, positive regard for mental health workers, and mutual mistrust (from highest to lowest level of endorsement). The same procedure identified the relative endorsement of five factors extracted from items about potential barriers: inadequate resources, confidentiality, gaps in interagency processes, unrealistic expectations, and professional knowledge domains and boundaries. CONCLUSIONS: Mental health and child protection professionals believe that collaborative practice is necessary; however, their efforts are hindered by a lack of supportive structures and practices at the organizational level. 相似文献

Since 1980 when Zimbabwe obtained political independence, special education has not received the same priority as the entire education system. One of the manifestations of this discrepancy is the shortage of qualified special education teachers in the country. In order to address this trend and promote the development of special education, researchers have suggested the need for professional development in the area of special education. The purpose of this study was to identify the special education professional development needs of both special and general education in-service teachers in Zimbabwe. A semi-structured survey instrument, developed by the first and second authors, which included open- and closed-end questions was used in this study. The sample consisted of 204 schoolteachers drawn from two school districts of Zvishavane and Gwanda. The participating schoolteachers overwhelmingly expressed the need for more professional development in the area of special education. The schoolteachers also identified several topics that they considered to be important for professional development. 相似文献

In the emerging digital economy, the management of information in aerospace and construction organisations is facing a particular challenge due to the ever-increasing volume of information and the extensive use of information and communication technologies (ICTs). This paper addresses the problems of information overload and the value of information in both industries by providing some cross-disciplinary insights. In particular it identifies major issues and challenges in the current information evaluation practice in these two industries. Interviews were conducted to get a spectrum of industrial perspectives (director/strategic, project management and ICT/document management) on these issues in particular to information storage and retrieval strategies and the contrasting approaches to knowledge and information management of personalisation and codification. Industry feedback was collected by a follow-up workshop to strengthen the findings of the research. An information-handling agenda is outlined for the development of a future Information Evaluation Methodology (IEM) which could facilitate the practice of the codification of high-value information in order to support through-life knowledge and information management (K&IM) practice. 相似文献

The AIDS epidemic has created many orphans around the globe. A majority of these orphans live in sub‐Saharan Africa. Children orphaned by HIV/AIDS face many daunting challenges in their struggle to cope with life. The issues they face due to the loss of their parent(s) include poverty, the stigma associated with HIV/AIDS and stress. This study carried out by Morgan Chitiyo of Southern Illinois University Carbondale, Darlington Changara of Midlands AIDS Caring Organisation and George Chitiyo of Tennessee Technological University discusses how different psychosocial and educational interventions have been developed to help the children to overcome these challenges. However, few of the interventions have been empirically tested to determine their efficacy. The authors set out to evaluate the treatment acceptability of a psychosocial support programme using a group of teachers who had received training and were participating in the implementation of the programme across their schools. Findings from the study indicate high acceptability ratings of the programme. 相似文献

The AIDS pandemic has orphaned hundreds of thousands of children worldwide and most of these are in sub-Saharan Africa. Being orphaned by AIDS creates peculiar circumstances which may affect the children's ability to benefit from regular education. The impact of vulnerability on children's well-being has been documented by UNAIDS, UNICEF and by other organizations and writers. This study sought to ascertain the effectiveness of implementing psychosocial support (PSS) among children who are orphaned by AIDS in improving their schooling outcomes. A total of 20 children with ages ranging from 10 to14 years, attending four different primary schools located in the rural wards of Mberengwa district of Zimbabwe were involved in this study. All the children showed signs of emotional need and they were lagging behind in their academic work. Psychosocial support was provided to these children over a period of eight months resulting in improvements in several areas, including schoolwork during and after the intervention period. 相似文献
