Over the past 20 years most countries, particularly developing countries, have seen a large increase in the number of students seeking higher education. A consequence of this growth is increasing pressure on teaching staff and institutions, usually resulting in, among other effects, increased class size. Large classes of between 300 and 1,000, and even more, at the undergraduate level are not uncommon in a number of countries (Mulryan-Kyne in Teach High Educ 15(2):175–185, 2010). Large classes are often perceived as one of the major obstacles to the attainment of quality education. Despite the difficulties associated with teaching and learning in large classes, they remain a reality in many countries affecting learners across all levels of the education system and are often the only perceived option available to meet growing demand for higher education in Sub-Saharan Africa (Mohamedbhai in The effects of massification on higher education in Africa. Report from the Working Group on Higher Education of the Association for the Development of Education in Africa, 2008). We contend that the challenges of delivering large classes can be confronted, and in many ways diminished, through the use of current and emerging technologies and enhanced faculty development. In this expository paper, we present findings from project activities focused on higher education faculty development and capacity building. The findings include both formative and summative development activities, as well as data collected in faculty professional development workshops and the results of two surveys. We use these data to lay out issues, challenges (e.g., skills, resources, logistics—including poor campus infrastructure), and opportunities (e.g., mobile capacity, distance tools such as Moodle) of large class pedagogy using a design-based research framework.  相似文献

The purpose of this study was to compare the views of Finnish and US preschool teachers, administrators and parents on appropriate educational practices for children aged 3‐5. To obtain a measure of their attitudes toward quality practices with children, a 26‐item instrument was adapted from Developmentally Appropriate Practices in Early Childhood Programs Serving Children from Birth Through Age 8. Researchers in the USA and Finland were asked to administer the instrument to subjects they considered to be ‘representative’ of teachers, administrators and parents in their respective countries. Analysis‐of‐variance procedures were then used to determine the differences in views to quality programmes among the three groups in both countries. No significant differences were found among the three groups in the Finnish sample (F(2,69) = 1.34, p = ns). Among the US group, the parents were found to score significantly less than administrators (F(2,120) = 7.85, p < 0.0006). Multivariate analyses of variance procedures showed that administrators from the two countries did not differ significantly in any of the areas under study. The two areas where teachers tended to differ significantly were those of ‘teaching strategies’ (t = 3.13, df = 100, p = 0.002) and ‘language development’ (t = 3.98, df = 89, p = 0.000). Teachers in the USA tended to take a more structured approach to instruction in preschool programmes, using teacher‐directed (less appropriate) approaches and providing children with (less appropriate) drill and practice on language skills. Parents in Finland appeared more supportive of developmentally appropriate practices than their US counterparts and their views were more generally congruent with those of teachers and administrators. This study suggests that the construct of ‘appropriateness’ of beliefs/practices for children may be of value in comparative international child‐care studies, and it raises the issue of why a greater congruence in beliefs/practices exists in some countries.  相似文献

A survey covering the scientific and social aspects of climate change was administered to examine U.S. undergraduate student mental models, and compare knowledge between groups based on major and environmental group membership. A Knowledge Score (scale 0–35, mean score = 17.84) was generated for respondents at two, central East Coast, U.S. universities (n = 465). Elements of student mental models examined include environmental issue confusion, skepticism, and self-reported understanding. This study finds that students frequently confuse climate change with other environmental issues, and that a substantial majority of students do not have an understanding of climate change that closely matches the scientific model. These misconceptions extend to their understanding of mitigation actions. Environmental group membership is shown to be a greater determinant of climate change knowledge than enrollment in a science major.  相似文献

Background: This study is located in the general context of recent research on family life in England, ‘gifted and talented’ education policy and the significance of parental engagement. There is strong evidence that parental involvement has a significant and positive effect on children’s development and achievement. Although a great deal of work has been done on identifying general patterns of good practice, there is a gap in the literature regarding the support needs of parents of gifted and talented children from lower socio-economic backgrounds.

Purpose: The aim of this UK-based study was to explore what support such parents had received and what support they felt they needed to better promote their children’s development and achievement.

Sample: An opportunity sample of 21 parents with youngsters aged 14–16 identified as ‘gifted and talented’ by their schools, as part of UK government policy, took part in the study. The students attended a university-based intervention programme, which was designed to raise the students’ aspirations and achievement. The students were from schools within areas of relative social deprivation and, most qualified for free school meals.

Design and Methods: In-depth semi-structured interviews were carried out to capture the authentic voice of the parents. Data was analysed using both pre-determined and emerging codes.

Results: Sixteen of 21 of the parents had good, supportive relationships with their children and 15 of 21 had high aspirations for them. However, 18 of 21 of the parents felt unable to engage with their child’s learning in the home. They also felt inadequate in their knowledge and experience to help their children with subject choices and advise on matters relating to Higher Education. Parents did not perceive their wider family or the wider community as supportive, nor did they expect them to be. Peer groups were seen as threats to their children’s well-being and advancement. Schools were highly rated for relationships but offered no specific support to these parents.

Conclusions: We conclude that although parental involvement is acknowledged in defining children’s life chances, parents in our sample, nonetheless, seemed to be being forced to ‘go it alone’. Within the limitations imposed by our small sample, we raise questions about the implications of the study.  相似文献

Workforce downsizing is becoming an increasingly common outcome of organizational restructuring. Recent studies have focused on the victims of downsizing, the employees laid off. Unfortunately, little has been said about what happens to the “survivors” of downsizing. This qualitative report documents the perspectives of a small company's layoff survivors. It examines factors that affect retained employees' performance. A conceptual framework for evaluating how downsizing impacts job performance is presented. Three main factors–need for security, desire for justice, and level of job enrichment–found to have an impact on employees' ability to actively support the company in its quest for competitive edge, are discussed.  相似文献

The present study aimed to investigate pre-sleep behaviours (including evening electronic device use) and sleep quantity in well-trained athletes. Seventy well-trained athletes (44 females, 26 males) aged 21 ± 4 y from a range of team and individual sports were asked to complete an online sleep diary for 7 days. The sleep diary included questions about pre-sleep behaviours (e.g. napping, caffeine intake), electronic device use in the 2 h prior to bedtime (e.g. type of device and duration of use) and sleep (e.g. time in bed, sleep onset latency). On average, athletes spent 8:20 ± 1:21 h in bed each night. Associations between age, time in bed and sleepiness suggested that younger athletes spent more time in bed (= -0.05, p = 0.001) but felt sleepier (r = -0.32, p < 0.01) than older athletes. On average, athletes mostly used electronic devices for 0–30 min prior to sleep. The use of multiple devices in the evening was associated with more perceived difficulty in falling asleep (= 0.22, p = 0.03), but no associations existed with other sleep variables. In summary, younger athletes may require later start times or improved sleep quality to resolve excessive sleepiness.  相似文献

BackgroundDespite the well-established health benefits of physical activity (PA) for young people (aged 4–19 years), most do not meet PA guidelines. Policies that support PA in schools may be promising, but their impact on PA behavior is poorly understood. The aim of this systematic review was to ascertain the level and type of evidence reported in the international scientific literature for policies within the school setting that contribute directly or indirectly to increasing PA.MethodsThis systematic review is compliant with Preferred Reporting Items for Systematic Review and Meta-Analysis guidelines. Six databases were searched using key concepts of policy, school, evaluation, and PA. Following title and abstract screening of 2323 studies, 25 progressed to data synthesis. Methodological quality was assessed using standardized tools, and the strength of the evidence of policy impact was described based on pre-determined codes: positive, negative, inconclusive, or untested statistically.ResultsEvidence emerged for 9 policy areas that had a direct or indirect effect on PA within the school setting. These were whole school PA policy, physical education, sport/extracurricular PA, classroom-based PA, active breaks/recess, physical environment, shared use agreements, active school transport, and surveillance. The bulk of the evidence was significantly positive (54%), 27% was inconclusive, 9% was significantly negative, and 11% was untested (due to rounding, some numbers add to 99% or 101%). Frequency of evidence was highest in the primary setting (41%), 34% in the secondary setting, and 24% in primary/secondary combined school settings. By policy area, frequency of evidence was highest for sport/extracurricular PA (35%), 17% for physical education, and 12% for whole school PA policy, with evidence for shared use agreements between schools and local communities rarely reported (2%). Comparing relative strength of evidence, the evidence for shared use agreements, though sparse, was 100% positive, while 60% of the evidence for whole school PA policy, 59% of the evidence for sport/extracurricular PA, 57% of the evidence for physical education, 50% of the evidence for PA in classroom, and 50% of the evidence for active breaks/recess were positive.ConclusionThe current evidence base supports the effectiveness of PA policy actions within the school setting but cautions against a “one-size-fits-all” approach and emphasizes the need to examine policy implementation to maximize translation into practice. Greater clarity regarding terminology, measurement, and methods for evaluation of policy interventions is needed.  相似文献
