Evaluating deaf students' readiness to meet the English language and literacy demands of postsecondary educational programs     

Bochner JH  Walter GG 《Journal of deaf studies and deaf education》2005,10(3):232-243

The purpose of this study was to investigate alternative methods for evaluating deaf students' readiness to meet the English language and literacy demands of postsecondary educational programs. In the first part of the study, scores obtained by a large sample of deaf students on the ACT Assessment (ACT Composite score and scores on the ACT English and Reading tests) were compared to their scores on various measures of English language and literacy skills. In the second part of the study, the performance of a smaller sample of deaf students on the ESL Reading and ESL Grammar/Usage components of COMPASS/ESL was compared to their performance on a set of concurrent measures of English skills. The results of this investigation demonstrate that neither the ACT Assessment nor COMPASS/ESL are appropriate for the full range of deaf students seeking admission to postsecondary educational programs. However, the ACT Assessment is appropriate for deaf students seeking admission to transferable (BS and AAS) degree programs, and the ESL Reading and Grammar/Usage tests appear to be appropriate for deaf students seeking admission to nontransferable (AOS) degree programs. Taken together, the combination of the ACT Assessment and COMPASS/ESL appear able to provide a valid, reliable, and coherent approach to admissions screening assessment for the full range of deaf students seeking admission to postsecondary programs.  相似文献

The Effect of Globalisation in Africa and the Choice of Language in Publishing     

Walter Bgoya 《International Review of Education/Internationale Zeitschrift für Erziehungswissenschaft/Revue internationale l'éducation》2001,6(2):283-292

This article shows us some of the problems of the domination of the ex-colonial languages for intellectual life in Africa. The author notes that English serves fundamentally the interests of those for whom it is both an export commodity and a language of conquest and domination. He argues that there is no compelling reason for adopting a foreign language as a national one. On the contrary, there is ample evidence that such linguistic imposition does more harm than good. When a language is artificially imposed, students are rarely able to master it sufficiently to work comfortably in it. Not only do they fail to acquire proficiency in the foreign language; they also lose proficiency in their own languages, becoming twice disadvantaged. The author sees dependency on a foreign language, like other forms of dependency, as a liability that a nation can ill afford. He quotes Ali Mazrui who raises the question: Will Africa ever effectively "take off" when it is so tightly held hostage to the languages of the former imperial masters?  相似文献

Computerized and Traditional Administration of Questionnaires: Psychometric Quality and Completion Time for Measures of Self-Concept     

Walter Peter Vispoel  Carrie Ann Morris  Linan Sun 《Journal of Experimental Education》2019,87(3):384-399

In two independent studies of questionnaire administration, respondents completed multidimensional self-concept inventories within four randomized research conditions that mirrored the most common administration formats used in practice: paper booklets with and without answer sheets and computer questionnaires with single versus multiple items per screen. Strong differences among conditions emerged for completion time, but not for psychometric properties of scores (means, variances, reliability coefficients, concurrent validity coefficients). Answer sheets increased completion time by 24% to 34%, single-item displays by 20% to 25%, and computerization by 13% to 17%. Completion time was longer for multiple-alternative than for rating-scale items, but relative effects of answer sheets, single-item displays, and computerization remained consistent. We discuss implications for questionnaire construction and administration.  相似文献   

An exploratory investigation into factors affecting visual balance     

Walter Niekamp 《Educational technology research and development : ETR & D》1981,29(1):37-48

Throughout the history of art more attention has been given to pictorial balance than to any other principle of visual composition. When examining pictorial balance, the visual weights of significant elements within a given field must be taken into consideration. This study, by means of ocular photography and the analysis of eye fixations, examined factors that have an effect upon visual weight. Confirming earlier studies, the upper half of a visual field was found to have inherently greater visual weight than the lower half. While several researchers have attributed greater visual weight to the left side of a field, others have favored the right. Data from this study were not sufficiently reliable to indicate a preference for either side. Results were insufficient to support the hypothesis that the upper left quadrant has greater inherent visual weight than the upper right quadrant. While it was shown that the interrelationships between tone and size have an effect on visual weight, the exact nature of these relationships must await future investigation.  相似文献   

Ethene/norbornene copolymerization by [Me2Si(3-tertBuCp)(NtertBu)]TiCl2/MAO-catalyst     

Tran  Phu-Dennis  Kaminsky  Walter 《浙江大学学报(A卷英文版)》2003,4(2):121-130

Ethene/norbornene copolymerization by the catalyst system [Me₂Si(3-^tertBuCp)(N^tertBu)]TiCl₂/MAO was investigated in detail at 30 °C, 60 °C, and 90 °C. A mass flow controller was used in this work to obtain kinetic data and investigate temperature's effects on activity, norbornene incorporation, copolymerization parameter, microstructure, glass transition temperature, and molar masses were described. High copolymerization valuesr _ξ and high alternation are determined. The number of isotactic alternating sequences is much higher than that of the syndiotactic alternating sequences.  相似文献   

Individualization of data-segment-related parameters for improvement of EEG signal classification in brain-computer interface     

曹红宝  BESIO  Walter  G  JONES  Steven  周鹏 《天津大学学报(英文版)》2010,16(3):235-238

In electroencephalogram (EEG) modeling techniques, data segment selection is the first and still an important step. The influence of a set of data-segment-related parameters on feature extraction and classification in an EEG-based brain-computer interface (BCI) was studied. An auto search algorithm was developed to study four datasegment-related parameters in each trial of 12 subjects’ EEG. The length of data segment (LDS), the start position of data (SPD) segment, AR order, and number of trials (NT) were used to build the model. The study showed that, compared with the classification ratio (CR) without parameter selection, the CR was increased by 20% to 30% with proper selection of these data-segment-related parameters, and the optimum parameter values were subject-dependent. This suggests that the data-segment-related parameters should be individualized when building models for BCI.  相似文献
