The fault is in ourselves: looking at ‘failures in implementation’     

Razia Fakir Mohammed  Brian Harlech‐Jones 《Compare》2008,38(1):39-51

While implementers are often blamed, reformers themselves are usually responsible for sub‐optimal implementation of educational reform projects. This article shows that the conditions for successful implementation, which are known and accessible, are frequently ignored. The case study concerns a university that is engaged in in‐service teacher education reform in Pakistan, focusing on introducing a ‘learner‐centred’ approach in schools. The research identified severe shortcomings related to implementation of the new approach, mostly relating to a failure by the teacher‐educators to understand and adapt to the actual contexts in which the teachers work. Finally, we suggest reasons why there are so many instances of failed reforms in developing countries.  相似文献   

Serum gamma glutamyl transferase (γ-GT) activity in alcoholics with liver abscess and chronic alcoholics     

G. Rajagopal  K. M. Mohammed Rafi 《Indian journal of clinical biochemistry : IJCB》2005,20(2):198-199

Gamma Glutamyl Transferase (γ-GT) is a microsomal enzyme. Its activity in serum is assayed in alcoholics with liver abscess and alcoholics without liver abscess after screening by ultrasonography. The enzyme activity in serum is increased by 334% in the patients with liver abscess compared to normal control subjects (p<0.0001), and 172% when compared to patients with chronic alcoholism without liver abscess (p<0.0001). The enzyme activity was increased by 59.3% in the serum of patients without liver abscess compared to the normal control subjects (p<0.001). Measurement of γ-GT in serum appears to be a sensitive index in the diagnosis of alcoholics with liver abscess.  相似文献

具有不同宽槽数的矩形微带贴片天线多带特性研究     

刘元安 《东南大学学报》2004,20(1):10-15

主要研究了多带工作的特性,并通过设计矩形贴片微带天线--包含不同数目的并放置在两辐射端的槽, 进行分析. 分析基于MOM仿真软件包, 结论表明一个贴片上有3个槽的天线具有多带特性: 4个振荡频率分别在1. 6, 1. 8, 2. 65, 和4. 83 GHz, 并且具有足够的反射损耗和增益值. 同时证明了带有2对槽的贴片天线(槽分别位于两辐射端)有双带特性, 其振荡频率分别在1. 64和1. 8 GHz, 而且返回损耗和增益值很好.  相似文献   

Doing an effective job? Measuring the impact of casework     

Susannah Turner  Leisa Randall  Azra Mohammed 《Educational Psychology in Practice》2010,26(4):313-329

This article describes an initiative to evaluate the impact of educational psychologists’ (EPs’) casework. Previous studies have often focussed on evaluating processes or reducing outcomes to measurable units. The authors argue that qualitative research methods can be used to illuminate EP effectiveness. They describe a real world and proportionate methodology, crucially aimed at supporting self‐reflection and development. An evaluation of this initiative showed that it can demonstrate EP impact and has validity for individual and service improvement. Implications, including the need to face up to less than positive feedback, are discussed.  相似文献   

Ergogenic effects of precooling with cold water immersion and ice ingestion: A meta-analysis     

Hui C. Choo  Kazunori Nosaka  Jeremiah J. Peiffer  Mohammed Ihsan  Chris R. Abbiss 《European Journal of Sport Science》2018,18(2):170-181

This review evaluated the effects of precooling via cold water immersion (CWI) and ingestion of ice slurry/slushy or crushed ice (ICE) on endurance performance measures (e.g. time-to-exhaustion and time trials) and psychophysiological parameters (core [T_core] and skin [T_skin] temperatures, whole body sweat [WBS] response, heart rate [HR], thermal sensation [TS], and perceived exertion [RPE]). Twenty-two studies were included in the meta-analysis based on the following criteria: (i) cooling was performed before exercise with ICE or CWI; (ii) exercise longer than 6?min was performed in ambient temperature ≥26°C; and (iii) crossover study design with a non-cooling passive control condition. CWI improved performance measures (weighted average effect size in Hedges’ g [95% confidence interval]?+?0.53 [0.28; 0.77]) and resulted in greater increase (ΔEX) in T_skin (+4.15 [3.1; 5.21]) during exercise, while lower peak T_core (?0.93 [?1.18; ?0.67]), WBS (?0.74 [?1.18; ?0.3]), and TS (?0.5 [?0.8; ?0.19]) were observed without concomitant changes in ΔEX-T_core (+0.19 [?0.22; 0.6]), peak T_skin (?0.67 [?1.52; 0.18]), peak HR (?0.14 [?0.38; 0.11]), and RPE (?0.14 [?0.39; 0.12]). ICE had no clear effect on performance measures (+0.2 [?0.07; 0.46]) but resulted in greater ΔEX-T_core (+1.02 [0.59; 1.45]) and ΔEX-T_skin (+0.34 [0.02; 0.67]) without concomitant changes in peak T_core (?0.1 [?0.48; 0.28]), peak T_skin (+0.1 [?0.22; 0.41]), peak HR (+0.08 [?0.19; 0.35]), WBS (?0.12 [?0.42; 0.18]), TS (?0.2 [?0.49; 0.1]), and RPE (?0.01 [?0.33; 0.31]). From both ergogenic and thermoregulatory perspectives, CWI may be more effective than ICE as a precooling treatment prior to exercise in the heat.  相似文献   

Consumerisation in UK higher education business schools: higher fees,greater stress and debatable outcomes     

Abdul Jabbar  Bejan Analoui  Kai Kong  Mohammed Mirza 《Higher Education》2018,76(1):85-100

For many UK higher education business schools, the continued recruitment of UK, EU and international students is crucial for financial stability, viability and independence. Due to increasingly competitive funding models across the sector, many institutional leaders and administrators are making decisions typical of highly marketised consumer environments. Thus, this paper explores academics’ perceptions of the impact of consumerisation in UK higher education business schools. To achieve this, 22 business school academics were interviewed within three UK higher education institutions (HEIs) in the North of England. Participants had a minimum of three years teaching experience. Data was analysed using template analysis taking an interpretive approach. The findings indicate that academics perceived the introduction of tuition fees to have been the catalyst for students increasing demonstration of customer-like behaviour: viewing the education process as transactional, with the HEI providing a ‘paid for’ service. It is argued that these changes in UK higher education have created tensions between university leaders and academics, creating genuine dilemmas for those with decision-making responsibilities who must balance academic integrity and long-term institutional financial viability.  相似文献   

Optimising the blended learning environment: the Arab Open University experience     

Tahrir Hamdi  Mohammed Abu Qudais 《Open Learning》2018,33(1):46-62

This paper will offer some insights into possible ways to optimise the blended learning environment based on experience with this modality of teaching at Arab Open University/Jordan branch and also by reflecting upon the results of several meta-analytical studies, which have shown blended learning environments to be more effective than their face to face and online only counterparts. Three key elements will be presented as important ways for improving the blended learning environment: forging genuine collaborative partnerships between institutions in terms of the team-writing of Open and Distance Learning (ODL) material, adopting a more theoretically based instructional approach, such as the cognitive apprenticeship (CA) model, which emphasises making thinking visible and developing a comprehensive understanding of blended education in order to help students achieve their educational goals.  相似文献   

Prior knowledge in mathematics and study success in engineering: informational value of learner data collected from a web-based pre-course     

Katja Derr  Reinhold Hübl  Mohammed Zaki Ahmed 《European Journal of Engineering Education》2018,43(6):911-926

The article describes the development and evaluation of a web-based pre-course in mathematics, delivered to four cohorts of engineering students at a German university. Based on demographic, personal, and learning-related data relationships between students’ preconditions, their learning gains in the pre-course, and study success in the degree programme were analysed. The results support the existing literature in that domain-related prior knowledge and secondary school achievement play a dominant role regarding study success in engineering. The analyses also showed that the influence of cognitive predictors could only be compensated for by a strong learner engagement. At-risk students with high pre-course learning gains showed significantly better first-year performance. The number of self-tests a student attempted was positively related to pre-course learning gains and even to first-year performance, suggesting that this variable is a good indicator of student engagement.  相似文献
