A simple explicit recursive formula for the elements of the first column of Routh's array is presented. The use of this formula will eliminate the need for constructing the whole array.  相似文献

Previous research indicates that, prior to entering kindergarten, most children are exposed to some type of formal or direct mathematics instruction. However, the type of mathematical language and the frequency of its use vary greatly in terms of its emphasis on academic content. This study investigated the types and frequency of mathematical language used in six classrooms for children ranging in age from birth to five years. The study site was a quality early childhood setting at a state university in Southwest. Results indicated that utterances pertaining to spatial relations exceeded any other type of mathematical concepts by approximately twice the frequency. In addition, there was a paucity of higher level mathematical concepts observed. These data suggest a need for enhanced attention to higher level mathematical concepts explored in early childhood settings.  相似文献

Training efl/esl teachers for a peaceful Asia-Pacific region   总被引:1,自引:0,他引:1  
In this experimental study which is based on qualitative and quantitative data collection from an experimental and a control group, it has been found that when some educational terms in English Language Teacher Training programs are strengthened in meaning through some adaptations to better convey the message, their effectiveness is increased. Therefore, it is suggested that foreign or second language teachers in the Asia-Pacific region should not teach the target language only for linguistic and communicative purposes but also to introduce characteristics of different cultures and to contribute to educating people who enjoy similarities, respect differences and value human rights.  相似文献

In this paper, a novel oscillating flow polymerase chain reaction (PCR) device was designed and fabricated to amplify SPPS150 and salmonella typhi. In this new design, the samples are shuttled (oscillating flow) inside a microfluidic chip to three different temperature zones required for DNA amplification. The amplification cycle time has markedly been reduced as the reagent volume used was only about 25% of that used in conventional PCRs. Bubble formation and adsorption issues commonly associated to chip based PCR were also eliminated. Based on the performance evaluated, it is demonstrated that this oscillating flow PCR has the advantages of both the stationary chamber and continuous flow PCR devices.  相似文献

This paper is one of a pair that re-examines the evidence from a national initiative to train all teachers in England to bring them up to the level of newly qualified teachers, who are required to know when to use and when not to use information and communication technologies (ICT) in their professional practice. Reanalysis of data gathered for the 2004 evaluation uncovers the complexity of such professional development. The effectiveness of contrasting approaches to ICT-related teacher training was analysed using the national survey of 496 trainees and experts' reports on 11 of the 47 training providers. multilevel evaluation of professional development was shown to be robust for ICT teacher training, including a significant correlation between the views of experts and those of teachers. The presence of the middle level of 'organisational support and change' emerged as a particularly discriminating factor, indicating that higher-quality teacher training supports change in the classroom and in the school. Therefore, we recommend that all five of Guskey's levels be consistently adopted for the evaluation of ICT teacher training, and that research should also adopt a multilevel model. A second paper delves deeper to describe and contrast the highest and lowest-rated approaches to ICT teacher training.  相似文献

There is a high demand to develop and incorporate decision support tools, by the transportation sectors and other concerned agencies, to improve their infrastructure assets management under shrinking budgets and increasing demands. This paper develops a proof-of-concept Bayesian belief network (BBN) model to rank roads in a network system based on several key performance indicators (KPI) using a probabilistic framework. For a given road network, the proposed tool is capable of ranking or prioritizing the segment of roads for high level management objectives. To demonstrate the application of the proposed model, various scenarios are elaborated and discussed in detail. Finally, the sensitivity analysis is carried out to evaluate the effects of different KPIs.  相似文献

This study aims to investigate the relationship between past experience and the career mobility of 31 high-flying female academics from eight established Malaysian universities. Based on data gathered from in-depth interviews, it is discerned that the respondents' career mobility at the exploration stage is influenced by early exposure to learning, experience in secondary schools (especially at boarding schools), first-degree experience, and personal qualities. On the other hand, respondents' career mobility during the establishment and maintenance stages is attributed to graduate study experience, career centrality, family support, uniqueness of academic role, health consciousness and adherence to religiosity.  相似文献

Students' perceptions of the education environment influence their learning. Ever since the major medical curriculum reform, anatomy education has undergone several changes in terms of its curriculum, teaching modalities, learning resources, and assessment methods. By measuring students' perceptions concerning anatomy education environment, valuable information can be obtained to facilitate improvements in teaching and learning. Hence, it is important to use a valid inventory that specifically measures attributes of the anatomy education environment. In this study, a new 11‐factor, 132‐items Anatomy Education Environment Measurement Inventory (AEEMI) was developed using Delphi technique and was validated in a Malaysian public medical school. The inventory was found to have satisfactory content evidence (scale‐level content validity index [total] = 0.646); good response process evidence (scale‐level face validity index [total] = 0.867); and acceptable to high internal consistency, with the Raykov composite reliability estimates of the six factors are in the range of 0.604–0.876. The best fit model of the AEEMI is achieved with six domains and 25 items (X2 = 415.67, P < 0.001, ChiSq/df = 1.63, RMSEA = 0.045, GFI = 0.905, CFI = 0.937, NFI = 0.854, TLI = 0.926). Hence, AEEMI was proven to have good psychometric properties, and thus could be used to measure the anatomy education environment in Malaysia. A concerted collaboration should be initiated toward developing a valid universal tool that, using the methods outlined in this study, measures the anatomy education environment across different institutions and countries.
