This study examined the extent to which different measures of speechreading performance correlated with particular cognitive abilities in a population of hearing-impaired people. Although the three speechreading tasks (isolated word identification, sentence comprehension, and text tracking) were highly intercorrelated, they tapped different cognitive skills. In this population, younger participants were better speechreaders, and, when age was taken into account, speech tracking correlated primarily with (written) lexical decision speed. In contrast, speechreading for sentence comprehension correlated most strongly with performance on a phonological processing task (written pseudohomophone detection) but also on a span measure that may have utilized visual, nonverbal memory for letters. We discuss the implications of this pattern. 相似文献

A number of adult education innovations were introduced in Tanzania in the late 1960s and early 1970s. This article analyzes the context of three innovations, namely functional literacy, workers' education and the programme of the Folk Development Colleges. The analysis reveals that these innovations had firm roots within the socio-economic conditions prevailing in the country in the 1960s and 1970s, Nyerere's influence as President and Party leader, Tanzania's ideology of development, the policy of popular participation, the roots of educational policy in a humanistic philosophy of education, and indigenous education. Some of the factors which affected their implementation included lack of trained educators, inadequate financial resources, ineffective evaluation mechanisms, and a mis-match between participants' needs and actual programmes. It is suggested that there is a need to introduce economic innovations alongside educational innovations, to involve participants in determining their training needs, and to train and retain adult educators with a view to improving adult education initiatives in the country.
Zusammenfassung In Tansania wurden in den späten 60ern und den frühen 70ern einige Innovationen auf dem Gebiet der Erwachsenenbildung eingeführt. In diesem Artikel werden die Zusammenhänge zwischen drei Innovationen, nämlich funktionale Alphabetisierung, Arbeiterbildung und die Programme der Folk Development Colleges (Volksbildungsschulen), analysiert. Die Analyse zeigt, daß diese Innovationen in folgenden Gründen ihre Wurzeln haben: in den im Lande herrschenden sozialwirtschaftlichen Bedingungen der 60er und 70er Jahre, Nyerere's Einfluß als Präsident und Parteivorstand, Tansanias Ideologie der Entwicklung, der Politik der Volksbeteiligung, den Wurzeln der Erziehungspolitik in einer humanistischen Erziehungsphilosophie und im einheimischen Schulwesen. Einige der Gründe, die ihre Verwirklichung beeinflußten, lagen im Mangel an ausgebildeten Lehrern, unzureichenden Finanzquellen, ineffektiven Evaluierungs-mechanismen und einer schlechten Abstimmung zwischen den Bedürfnissen der Teilnehmer und den tatsächlichen Programmen. Der Autor stellt fest, daß es nötig sei, zusammen mit den Innovationen auf dem Gebiet der Erziehung auch wirtschaftliche Innovationen einzuführen, die Teilnehmer bei der Feststellung ihres Bedarfs an Bildung einzubeziehen und die Lehrer der Erwachsenen zwecks Verbesserung der Initiativen in der Erwachsenenbildung im Lande auszubilden und zu behalten.
Résumé Des innovations en matière d'éducation des adultes ont été introduites en Tanzanie à la fin des années 60 et au début des années 70. Cet article analyse le contexte de trois de ces innovations, à savoir l'alphabétisation fonctionnelle, l'éducation des travailleurs et le programme des Collèges du développement populaire. Cette analyse met en évidence que ces innovations étaient intimement liées aux conditions socio-économiques prévalant dans le pays à cette époque-là, à l'influence de Nyerere en tant que président et chef du parti, à l'idéologie tanzanienne de développement, à la politique de participation populaire, à la politique d'éducation ancrée dans une philosophie éducative humaniste et à l'éducation indigène. Le nombre insuffisant de maîtres formés, l'inadéquation des ressources financières, les mécanismes inefficaces d'évaluation et la disparité entre les besoins des participants et les programmes proposés sont quelques-uns des facteurs ayant entravé leur mise en oeuvre, L'auteur suggère qu'on introduise des innovations économiques à côté de celles éducatives, que les participants prennent part à la définition de leurs besoins de formation, qu'on forme et retienne les éducateurs d'adultes afin d'améliorer les innovations adoptées par le pays en matière d'éducation des adultes.相似文献

A comparative study was made on the tissue specific expression of glutathione transferases (GST) in brain and testis after
exposure of rat to phenobarbitol (PB) and β-methylcholanthrene (MC). Glutathione transferases, a family of multifunctional
proteins are involved in intracellular transport processes and in detoxication of electrophilic xenobiotics by catalyzing
reactions such as conjugation, isomerization, reduction and thiolysis. On purification, the yield of GST proteins by affinity
chromatography was 39% in testis and 32% in brain. The affinity purified testis GSTs were resolved by chromatofocusing into
six anionic and four cationic isozymes, and in brain glutathione transferases were resolved into four anionic and three cationic
isozymes, suggesting the presence of multiple isozymes with Yc, Yb, Yβ and Yδ in both of them. In testis and brain, these
isozymes at identical pI values showed variable functions with a battery of substrates and the cationic isozymes of brain
and testis showed identical properties in CHP (cumene hydroperoxide) at pH values of above 7.0. Substrate specificity studies
and immunoblot analysis of testis and brain proteins revealed that they play a predominant role in the detoxication of phenobarbitol
or β-methylcholanthrene. Expression of the isozymes in testis and brain on exposure to PB and MC indicated elevated subunit
variation. In both testis and brain, Yδ of π class was expressed on PB treatment and Yc of α class and Yβ of μ class was expressed
in MC treated testis and only Yc was predominantly expressed in MC treated brain. Thus these subunits expression is considered
as markers for carcinogenesis and specific to chemical toxicity under phenobarbitol and β-methylcholanthrene stress.

The purpose of this paper is to highlight some observations made in a recent study aimed at describing the nature of current practice in the teaching of mathematics in Zimbabwean infant and primary school grades. It has been observed that the teaching is characterized by, among other things, a preponderance of chorus responses, non‐questioning pupils, lack of problem solving, teaching more than mathematics, more product and less process orientation, and small group work with group leaders. It is proposed that if teachers wish to improve the quality of their teaching then an appropriate starting point is that of apprehending and understanding what they currently do in their classrooms. Such an understanding can be developed through deliberate and serious observation of and reflection on their own current practice. This paper is intended to stimulate that process. It is also suggested that the observations described here can be turned into research questions for investigations that can provide insights into ways of increasing effectiveness of mathematics teaching and learning in primary schools. 相似文献

This study is an examination of the relationship of perceived social support and adolescents' adjustment behaviors over time. The sample (n = 82) included students from two at‐risk urban middle schools. Utilizing two measures, the Child and Adolescent Social Support Scale (CASSS; C. K. Malecki, M. K. Demaray, & S. N. Elliott, 2000) and the Behavior Assessment System for Children, Self Report of Personality (BASC; C. R. Reynolds & R. W. Kamphaus, 1998), data were collected at three time points. Results point to a relationship between social support and student adjustment behaviors over time. Specifically, support from parents was related to clinical maladjustment and emotional symptoms one year later. In fact, parent support was still related to clinical maladjustment one year later even after students' earlier levels of clinical maladjustment were taken into account. Parent support was also related to personal adjustment in the short term (6 months). Classmate support was related to students' emotional symptoms one year later. Finally, school support was related to school maladjustment one year later even after students' earlier school maladjustment was taken into account. Implications for school psychologists are discussed. © 2005 Wiley Periodicals, Inc. Psychol Schs 42: 691–706, 2005. 相似文献

The relationship among students' reading performance, their behavior (task-focused behavior, emotional stability, and compliant behavior) in the classroom, and the teacher's skills was investigated in 66 third-grade classrooms. Results from this study showed the students' reading performance and their behavior in the classroom are all significantly interrelated. Better reading performance at the beginning of the school year goes with better behavior at the end of the school year. In turn, better behavior at the beginning of the school year goes with better reading performance at the end of the school year. The teacher can improve the behavior of the students by providing high-quality reading instruction. Some teacher skills have differential effects, however, on the various behavioral aspects. The implications for the educational practice as well as for future research are discussed. 相似文献

Retrieval practice has been shown to benefit learning. However, the benefit has sometimes been attenuated with more complex materials that require integrating multiple units of information. Critically, Tran et al. Psychonomic Bulletin & Review, 22, 135–140 (2015) found that retrieval practice improves sentence memory but not the drawing of inferences from the same sentences. In three experiments, we investigated whether this lack of benefit of retrieval practice for inferential ability was due to the presentation format of the material. Participants studied four sets of seven to nine related sentences by practicing retrieval for two sets and rereading the other two sets. A final test was given 2 days later. When sentences were presented one at a time during study/practice as in Tran et al., we found no effect of retrieval practice on a test requiring inferential reasoning. When sentences in a set were presented simultaneously during study/practice, retrieval practice in the form of fill-in-the-blank testing (experiments 1 and 2) and free recall (experiment 3) aided later deductive inference more than rereading. Our findings suggest that retrieval practice can improve deductive inference, but in order to optimize its utility, the format in which the material is presented during practice must not hinder relational processing of the individual sentences. 相似文献

Studies investigating the post-high-school vocational status of individuals with disabilities have frequently found that these individuals are more likely to be unemployed, underemployed, or employed part-time, when compared to nondisabled peers. Transition programs are needed for adolescents with disabilities to facilitate their vocational success. The current study surveyed 80 high school students with learning disabilities (LD) and 80 nondisabled (NLD) peers to determine their transitional needs. Results indicated that (a) more students with LD than NLD students are involved in transition programs; (b) career goals were established by the majority of both groups; (c) parents provided most of the assistance in making career decisions; and (d) twice as many NLD students as students with LD wanted to go to college, while twice as many students with LD as NLD students wanted to enter the job market. More students with LD than NLD students were aware of vocational rehabilitation (VR) services, but the number was still below 50%. The majority of the information about VR services came from the school. 相似文献
