Drawing on a combination of prior experience, theoretical stance, and intuition, along with pedagogical practices identified to be effective in addressing diversity with teacher candidates, a model for teaching multicultural education to teacher candidates was designed. This study examined how particular elements of this model were effective in developing teacher candidate’s cultural competence. The results indicate that teacher candidates gained substantial knowledge about and experiences with issues of diversity by the end of the course. Participants pointed to the multiple methods employed in the class; in particular the interactive strategies, group work, diverse cultural experiences, and opportunities to critically reflect on these experiences as accounting for their gains. Their sense of ownership and understanding has given them the ability to use these strategies in their own future work. Implications for research and teacher education are discussed.  相似文献

Abstract

Purpose: This study developed a framework for quality assessment of diagnoses and advice given at plant clinics.

Design/methodology/approach: Clinic registers from five plant clinics in Uganda (2006–2010) were used to develop quality assessment protocols for diagnoses and advice given by plant doctors. Assessment of quality of diagnoses was based on five validation criteria applied on the ten most common crops. Quality of advice was assessed for the four major problems considering efficacy and feasibility.

Findings: The quality of diagnoses varied between crops, from 68% completely validated in maize to 1% in tomato. Complete and partially validated diagnoses were 44% of all queries. The remaining 56% were rejected. Several basic weaknesses were found in data recording and symptom recognition. A greater consistency and precision in naming diseases would increase the number of completely validated diagnoses. The majority of recommendations (82%) were assessed ‘partially effective’. ‘Best practice’ was recommended for 10% and ineffective advice was given in 8% of the cases with considerable variation between diseases.

Practical implications: Plant doctors need more training in symptom recognition, pest management and record keeping as well as better technical backstopping to solve unknown problems. Common standards and procedures for clinic data collection and analysis should be established, and roles and responsibilities clearly defined.

Originality/value: This is the first time plant clinic registers have been used to systematically assess quality of plant clinic services. Apart from being a valuable tool for quality assessment of extension, the plant clinic registers constitute a novel source of regular information about pests, diseases and farmer demand that can help improve decision-making of extension service providers, researchers, plant health authorities as well as information and technology providers.  相似文献

The study investigated the extent of adoption of electronic theses and dissertations in university libraries in Nigeria. Data collection for the study was via online questionnaire. The study revealed that digitization of theses and dissertations started between 1980 and 1995. It was found that only a few university libraries have embraced digitization of theses and dissertations in Nigeria. Benefits of electronic theses and dissertations were identified as improving university ranking and visibility, increasing access to the theses and dissertations, saving space in the library, enabling others link to the work with persistent URLs, preserving the work for future generations, and saving costs for students. Challenges such as unstable internet connectivity, lack of funding, irregular power supply, lack of information technology personnel, absence of electronic theses and dissertations submission policy, and copyright issues were identified. It is hoped that the study might provide insights useful for librarians planning to embark on the digitization of theses and dissertations project.  相似文献

This research study explores the use of different lab material, investigating which types of materials contribute the most to the delivery and support of laboratory (lab) sessions to design, skill‐based and technical courses in higher education in the UK. A qualitative research methodology was employed for this investigation and included both key stakeholders in academia, including 75 students and 12 tutors. An investigation was also conducted tracking student activity on the university's e‐learning facility (U‐link). Our key findings indicate that overall electronic material is considered the most effective type of material for the delivery of a lab session. This is followed by print, video and lastly audio material according to student responses and video, print and audio material according to tutor responses. Student and tutor responses varied per individual module/subject area. Video material was regarded by students and tutors as the most effective type for the delivery of skill‐based lab sessions and generally for independent learning, and electronic material was regarded as the most effective type for the delivery of technical and design lab sessions. Lastly, student tracking revealed that the introduction of video lab material in two modules increased the average time spent by students on U‐link by 58% for the technical module and 97% for the skill‐based module respectively.  相似文献

This article examines the social forces underlying FIFAgate. Why do corrupt practices, which are often highly consolidated or even institutionalized, suddenly become scandalous? What is a scandal? Why did FIFA fall into crisis in 2015 and not before? To answer these questions, it is necessary to look at the sequence of thrusts and parries between all the parties involved. Our analysis embraces the notion that social processes are based on relationships in order to provide insights into why and how denunciations can lead to long-tolerated corrupt practices suddenly becoming compromising enough to force an organization’s leaders to implement measures that would have previously been unimaginable. We use multiple sources to examine the emergence of FIFAgate and the way FIFA overcame previous critical situations, describing how FIFA neutralized earlier allegations and developed a remarkable ‘resilience’ to scandal. Finally, we analyse the successive mobilizations whose domino effect led to the emergence of FIFAgate and the measures FIFA took to contain the scandal. Our research enabled us to draw up a new theoretical model for analysing corruption scandals.  相似文献

In developing countries, education is regarded as a public good that must be publicly provided. Due to the perceived positive correlation between education and development in development-hungry Africa, the education sector has, over the years, been receiving very generous budgetary allocations. Today, however, particularly post-2008, there are moves to re-define education as a private good, consequently, not deserving of public provision. As a result, there are persistent calls for alternative ways of providing education, particularly at tertiary levels. Similarly, in Botswana, there are developments that unmistakably suggest that the time is ripe for alternative ways of providing tertiary education, mainly, cost-sharing. To be sure, the Ministry of Education and Skills Development drastically cut sponsorships during the 2016/17 academic year. The general lesson from the Botswana case is that there is a need to continually interrogate the architecture of public expenditure. If problems are discovered, the architecture must be promptly reconfigured.  相似文献

This paper focuses on the ways in which five- to seven-year-old primary school children in a Black/African township in South Africa construct and experience ‘free play’ in the classroom. Findings highlight the gendered manner in which play is constructed and constantly policed by these young children during ‘free play’. By foregrounding the young children’s gendered constructions and experiences of ‘free play’, the paper challenges the common sense teacher perceptions and constructions of children’s play that suggest children have ‘free choice’. The paper reveals that play is far from a ‘free’ activity as it is heavily constrained by specific contextual gender norms and expectations which limit possibilities by reproducing polarised versions of gender and perpetuate gender inequalities. Implications focus on the ways in which teachers can work with children to challenge the boundaries of gender during ‘free play’.  相似文献

This qualitative study analyzed the English language learning difficulties of 13 purposively chosen Korean students relative to their sociolinguistic competence, motivation in using the English language, and cultural factors. Interview responses were transcribed, categorized and thematised according to saliency, meaning and homogeneity. The findings of the study disclosed that, on the whole, while the subjects never had the opportunity to use the English language in Korea, they use it almost everywhere in the Philippines. Their difficulties exist both in daily conversation and in the academic setting. Such difficulties are attributable to both the subjects’ and the Filipinos’ different entry points in the learning and use of English. Despite cultural barriers in communication, however, the Koreans studying in the Philippines are instrumentally motivated to learn the English language.  相似文献

Individuals with schizophrenia have a greater risk for cardiometabolic risk factors (e.g. central obesity, insulin resistance, hypertension and dyslipidaemia), cardiovascular diseases and mortality. This risky profile may be explained by the adverse effects of antipsychotic medications and an unhealthy lifestyle (e.g. smoking, poor nutrition and low physical activity). In the general population, physical activity has been shown to be the optimal strategy to improve both cardiometabolic parameters and cardiorespiratory fitness levels. Accordingly, an emerging literature of non-pharmacological interventions (e.g. cognitive behavioural therapy, diet and physical activity) has been studied in individuals with schizophrenia. Therefore, the purpose of this review was 1) to conduct a critical literature review of non-pharmacological interventions that included some kind of physical activity (including supervised and unsupervised exercise training) and target cardiometabolic risk factors in individuals with schizophrenia. 2) To describe the contribution of physical activity alone by reviewing trials of supervised exercise training programmes only. A literature review via systematic keyword search for publications in Medline, PubMed, Embase and PsycINFO was performed. Many non-pharmacological interventions are efficient in reducing cardiovascular disease risk factors when combined with physical activity. Supervised physical activity has been successful in decreasing cardiovascular disease risk, and aerobic interval training appears to provide more benefits by specifically targeting cardiorespiratory fitness levels. In conclusion, physical activity is an effective strategy for addressing cardiovascular disease risk in individuals with schizophrenia. Long-term studies are needed to evaluate the feasibility and impact of exercise training programmes in individuals with schizophrenia.  相似文献

Although the link between sagittal plane motion and exercise intensity has been highlighted, no study assessed if different workloads lead to changes in three-dimensional cycling kinematics. This study compared three-dimensional joint and segment kinematics between competitive and recreational road cyclists across different workloads. Twenty-four road male cyclists (12 competitive and 12 recreational) underwent an incremental workload test to determine aerobic peak power output. In a following session, cyclists performed four trials at sub-maximal workloads (65, 75, 85 and 95% of their aerobic peak power output) at 90?rpm of pedalling cadence. Mean hip adduction, thigh rotation, shank rotation, pelvis inclination (latero-lateral and anterior–posterior), spine inclination and rotation were computed at the power section of the crank cycle (12 o'clock to 6 o'clock crank positions) using three-dimensional kinematics. Greater lateral spine inclination (p?p?p?相似文献
