Dictation is a complicated process of decoding information and reorganizing mean- ing of an utterance and it has long been used to measure students' language profi- ciency and help them to develop accuracy in listening and writing. However, many English majors have poor performance in dictation of TEM-4. The paper tries to dis- cuss the fundamental factors that prevent students from obtaining a relatively high score in dictation and suggests some ways to deal with the problems.  相似文献

In recent years, reading scholars have increasingly attended to children’s responses to picturebook page breaks, reasoning that the inferences young readers make during the turning of the page are central to understanding how children construct continuous narratives in semiotically rich texts. In this paper I argue that comics (including comic books and graphic novels) offer similar gap-filling affordances as picturebooks, but for older children and adolescent readers. A major site of meaning-making in comics is the “gutter” between panels. This is where much of the magic occurs for readers while transacting with the medium. Since the comics medium is popular with many students and has received increased attention from teachers, researchers, and curriculum developers during the multimodal and multiliterate turns of the past decades, I argue that it is vital for educators not only to use comics in their classrooms, but to focus explicitly on gutters in order to exercise the medium’s full potential. Pulling from numerous sources, I provide several pedagogical activities that emphasize gutters as rich sites of constructing meaning.  相似文献

In Canada there exists a noteworthy educational initiative referred to as Environmental Studies Programs (ESPs). These secondary school programs are interdisciplinary, helping to link subject matter and encouraging student responsibility. The results of three case studies of Ontario ESPs indicate that program participation has ‘real world’ applications and creates a safe space for genuine dialogue and critical reflection, and that students experienced changes in environmental attitudes and behaviors as a result of program participation. These findings offer further documentation of the benefits of integrated ESPs, including increased student engagement, learning experiences that are practical and relevant to students’ lives, experiential learning that is memorable and opportunities for development of social and interpersonal skills.  相似文献

Although many nations advocate for the full inclusion of people with intellectual disabilities in all realms of life, these individuals are nevertheless still frequently excluded. One field of life that has rarely been considered central for inclusion of people with intellectual disabilities is military service. A unique programme was developed that provides an opportunity for people with intellectual disabilities to serve in the military in Israel. The centrality of the military within Israeli society, along with the aims and phases of the project are described, and brief evidence of the impact of the programme is provided.  相似文献

Coaxial liquid-liquid flows were numerically studied in a nesting two-tube system. Calculations were carried out when various exit-lengths (meaning length differences between the two tubes) were used. Numerical results indicated that there exists a certain range of exit-length for the liquid-liquid flows to form stable and smooth interfaces, which requires that the exit-length should roughly be less than 5.6 times the outer tube diameter. In this range, interface instability is effectively restrained and the core fluid shows a phenomenon of die swell. When the exit-length is about 1.6 times the outer tube diameter, the core fluid has the greatest diameter size in the shell fluid. Velocity distributions at the outer tube exit favor formation of a continuous and stable core-shell structure.  相似文献

Teachers’ positive attitude is most critically and consistently associated with successful inclusion. However, little is known about teachers’ first-hand encounters with inclusive education in Singapore. We present findings from a qualitative study on inclusion based on focus group interviews with 202 teachers from 41 resourced primary schools. The data were transcribed and coded using Interpretive Phenomenological Analysis and NVIVO software. Two broad clusters identified were teachers’ positive and negative experiences in implementing inclusion. More reference was made to negative than positive experiences. The most dominant negative experience was stress from challenging behaviours and instructional difficulties of catering adequately for diverse needs in the same classroom. The most salient positive experience was satisfaction with pupils’ progress and new learning for teachers. Classroom practices that facilitated inclusion and the value of training in shaping teachers’ attitudes towards inclusion were highlighted.  相似文献

This study was an exploratory of the Landes initiative to supply all pupils and teachers with portable computers and Internet at school. These surveys involved 817 pupils and parents and produced a response rate of 98% for pupils from the first survey at the beginning of the year and 798 pupils at the end of the year. The approach, which consists of identifying any variances in individual perceptions of technology, was tested in an initial In-Tele research programme in which we were involved. The questionnaire-based survey reveals low usage of information technology in terms of teaching, with no difference between the portable and test groups. Moving on from the first level study, characterizing the sites and studying their viewing frequency produces the surprising outcome that the very high number of sites viewed actually conceals a much more pessimistic reality about pedagogical uses.  相似文献

A new method to detect multiple outliers in multivariate data is proposed. It is a combination of minimum subsets, resampling and self-organizing map (SOM) algorithm introduced by Kohonen,which provides a robust way with neural network. In this method, the number and organization of the neurons are selected by the characteristics of the spectra, e. g., the spectra data are often changed linearly with the concentration of the components and are often measured repeatedly, etc. So the spatial distribution of the neurons can be arranged by this characteristic. With this method, all the outliers in the spectra can be detected, which cannot be solved by the traditional method, and the speed of computation is higher than that of the traditional neural network method. The results of the simulation and the experiment show that this method is simple, effective, intuitionistic and all the outliers in the spectra can be detected in a short time. It is useful when associated with the regression model in the near infra-red research.  相似文献

ABSTRACT

In Sweden respite care is a legal right for families of children with disabilities. The Act Concerning Support and Service for Persons with Certain Functional Impairments (LSS) was passed in 1994. A previous study on respite care illuminated the municipalities’ view of the service. This article focuses on the parents’ view. The study is based on questionnaire responses from 141 families and interviews with 25 families. The results show that there is a widespread perception by families that there is not enough support and that the need for respite care is not met. There is also a lack of information about the service. More flexible, family‐oriented approaches are needed.  相似文献

The association between aberrant behaviour and depression was examined in a sample of 150 young males with Autism Spectrum Disorder via parent ratings on the Aberrant Behavior Checklist (ABC) and the Major Depressive Disorder subscale of the Child and Adolescent Symptom Inventory (CASI-4-D). Although several subscales of the ABC were significantly correlated with CASI-4-D scores, only the Irritability subscale was a significant predictor of CASI-4-D, but with different patterns of association across younger (6–12 years) and older (13–18 years) participants. When examined at an individual ABC item level, adolescents’ depression was primarily predicted the presence of temper tantrums that were associated with the introduction of variability or frustration at not getting his or her own way.  相似文献

A discriminant method for optimizing activity in nuclear medicine studies is validated by comparison with ROC (received operating characteristic)-curves. The method is tested in 21 single photon emission computerized tomography (SPECT), performed with a cardiac phantom. Three different lesions (Lb L2 and L3) were placed in the myocardium-wall by pairs fbr each SPECT. Three activities (84, 37 or 18.5 MBq) of 99mTc were used as background. Linear discriminant analysis was used to select the parameters that characterize image quality among the measured variables in the images [(Background-to-Lesion (B/Li) and Signal-to-Noise (S/N) ratios)]. Two clusters with different image quality (P=0.021 ) were obtained. The ratios B/Lj, B/L2 and B/L3 are the parameters used to construct the function with 100% of cases correctly classified into the clusters. The value of 37 MBq was the lowest tested activity for which good results for the B/Li ratios were obtained. The result coincides with the applied ROC-analysis (r=0.89).  相似文献

In this article, it is argued that the inordinate amount of time and attention given to the use of textbooks in education inadvertently leads to deadening miseducative experiences and creates a learning environment where what Dewey calls ‘consummatory experience’ is thwarted. In order to unpack this thesis, Dewey’s pragmatist aesthetics is engaged, and in particular, his concept of consummatory experience is defined and its temporal nature is elucidated by referring to two modes of time: chronological and phenomenological. Subsequently, the relation between teaching and consummatory experience is elucidated to uncover the reason why using textbooks is counterproductive.  相似文献

“积极、乐观、细致、易怒、善变、暴躁、无畏、被动、天真、朝气、大胆、优雅”等等,这些简单的词汇都是对一个人气质的形容。在这个世界上,就正如你无法找到两片绝对相同的树叶一样,你根本不可能找出两个完全相同的人!所以你与他或她或多或少都有不同的地方,不止是外貌,更多的是气质,不同之处就是你的气质所在。气质是一个人的心理面貌,即具有一定倾向性的各种心理特征的总和。这说明气质与专业确实是存在着联系的。气质决定的是一个人做事情的风格,思考问题的方式,选择一个与自己的气质比较匹配的专业可以少走弯路,更利于自己今后的发展…  相似文献
