This paper reports 3 studies comparing thereading and phonological skills of childrenwith Down syndrome (DS) and younger normallydeveloping children of similar reading level.In Study 1, the two groups did not differ insight word or nonword reading, but the childrenwith DS did marginally less well on syllablesegmentation, rhyme and phoneme detectiontasks. Group differences in syllable andphoneme awareness appeared attributable todifferences in verbal ability (BPVS, vocabularyknowledge); however, a significant impairmentin rhyme detection remained in an analysis ofsub-groups equated in vocabulary knowledge. Thedeficit in rhyme observed in DS was replicatedin Studies 2 and 3 using simplified tests ofrhyme judgement, with the majority of childrenwith DS performing at chance on the rhymemeasures. In contrast, the two groups did notdiffer in their ability to detect phonemes inany of the 3 studies and performed above chancein initial phoneme detection and alliterationjudgement tasks, although the identification offinal phonemes was at a much lower level. Correlational analyses indicated a relationshipbetween phonological skills and reading inboth groups. However, for children with DS,letter-sound knowledge did not predict readingwhereas it did for normal controls. It issuggested that children with DS do not possessfull phoneme awareness; although they canidentify initial phonemes in words, they do notunderstand phoneme invariance and may rely lesson phonological skills for reading thancontrols.  相似文献   

‘Beyond 2015’, within the modern/colonial global imaginary? Global development and higher education     

Sharon Stein  Vanessa de Oliveira Andreotti  Rene Suša 《Critical Studies in Education》2019,60(3):281-301

Efforts to emphasize higher education’s role in development have grown in recent years, but important questions remain about the motivations and effects of these initiatives. In this paper, we employ the concept of a ‘modern/colonial global imaginary’ to consider the impact of the enduring power relations and uneven politics of knowledge in the relationship between higher education and development. Specifically, we consider the Association of Commonwealth Universities’ (ACU) ‘Beyond 2015’ campaign, which was launched in anticipation of the new UN Sustainable Development Goals. We argue that despite the ACU’s intention to provide ‘a platform for diverse voices, particularly from the global South’, the campaign was structured in a way that discouraged dissenting perspectives. More broadly, we consider available possibilities and limitations for challenging mainstream development agendas.  相似文献   

How do teachers help children to learn? An analysis of teachers' interventions in computer-based activities     

Neil Mercer  Eunice Fisher 《Learning and Instruction》1992,2(4)

In British schools, educational software is normally used by children working under the supervision of a teacher, who will have set them specific tasks and organize them to work at the computer in pairs or groups. However, those theories of learning which have most influenced research into the design and use of educational software have been essentially concerned with individualized learning, and are insensitive to the nature of teaching and learning as a communicative, culturally-based process. The present paper discusses an alternative theoretical perspective, one derived from the work of Vygotsky. This is used in an analysis of interventions made by teachers in the computer-based activities of their pupils, using observational data gained from video-recordings of primary school classrooms. The usefulness of the theoretical perspective is evaluated, and implications for the development of computer-based activities are discussed.  相似文献   

The Schooling Experience of Adolescent Boys with AD/HD: An Australian Case Study     

Kathryn Gibbs  K. Louise Mercer  Suzanne Carrington 《International Journal of Disability, Development & Education》2016,63(6):608-622

This study explored the experience of schooling of six adolescent boys diagnosed with AD/HD from the perspectives of the boys, their mothers and their teachers. The study utilised social constructionism as the theoretical orientation and the Dynamic Developmental Theory (DDT) of AD/HD as the explanatory framework. Utilising a multiple, instrumental case-study, data were collected by means of semi-structured individual and focus group interviews as well as a review of school reports across a two year period. Findings of the study suggest that taking medication as prescribed together with supporting the students to make and manage friendships, utilising classroom strategies that support learning, and providing an engaging classroom environment are important considerations to promote a positive schooling experience for adolescents with AD/HD.  相似文献

From social interaction to individual reasoning: an empirical investigation of a possible socio-cultural model of cognitive development   总被引：2，自引：0，他引：2  

Rupert Wegerif  Neil Mercer  Lyn Dawes 《Learning and Instruction》1999,9(6):593

This study explores the theory that individual reasoning ability, as measured using standard reasoning tests, has part of its origin in dialogue with others. In the study, 64 eight- and nine-year-old children were taught the use of ‘exploratory talk’, a type of talk in which joint reasoning is made explicit. The relationship between the talk of the children and the solving of Raven's test problems was studied using discourse analysis of groups working together. The findings of the study support four claims: that use of exploratory talk can improve group reasoning, that exploratory talk can be taught, that the teaching of exploratory talk can successfully transfer between educational contexts and that individual results on a standard non-verbal reasoning test significantly improved as a result of the intervention teaching exploratory talk. Our results offer support for the hypothesis that experience of social reasoning can improve scores on measures of individual reasoning. The stronger hypothesis that general cognitive development is a product of induction into social reasoning remains in doubt.  相似文献   

Does spatial awareness training affect anatomy learning in medical students?     

Rene A. Gonzales  Gordon Ferns  Marc A. T. M. Vorstenbosch  Claire F. Smith 《Anatomical sciences education》2020,13(6):707-720

Spatial ability (SA) is the cognitive capacity to understand and mentally manipulate concepts of objects, remembering relationships among their parts and those of their surroundings. Spatial ability provides a learning advantage in science and may be useful in anatomy and technical skills in health care. This study aimed to assess the relationship between SA and anatomy scores in first- and second-year medical students. The training sessions focused on the analysis of the spatial component of objects' structure and their interaction as applied to medicine; SA was tested using the Visualization of Rotation (ROT) test. The intervention group (n = 29) received training and their pre- and post-training scores for the SA tests were compared to a control group (n = 75). Both groups improved their mean scores in the follow-up SA test (P < 0.010). There was no significant difference in SA scores between the groups for either SA test (P = 0.31, P = 0.90). The SA scores for female students were significantly lower than for male students, both at baseline and follow-up (P < 0.010). Anatomy training and assessment were administered by the anatomy department of the medical school, and examination scores were not significantly different between the two groups post-intervention (P = 0.33). However, participants with scores in the bottom quartile for SA performed worse in the anatomy questions (P < 0.001). Spatial awareness training did not improve SA or anatomy scores; however, SA may identify students who may benefit from additional academic support.  相似文献   

Connecting photosynthesis and cellular respiration: Preservice teachers' conceptions     

Mary H. Brown  Reneè S. Schwartz 《科学教学研究杂志》2009,46(7):791-812

The biological processes of photosynthesis and plant cellular respiration include multiple biochemical steps, occur simultaneously within plant cells, and share common molecular components. Yet, learners often compartmentalize functions and specialization of cell organelles relevant to these two processes, without considering the interconnections as well as the significance of the plant as an independent biological system functioning as a nested component within local and global ecosystems. Understanding connections among biological systems at macro and micro levels is important to biological literacy. This study examined preservice elementary teachers' conceptions of photosynthesis and plant cellular respiration, with attention to interconnections and systems. Participants were limited in their understanding of the processes impacting multiple ecological levels, and they held inadequate representations of interconnections between the processes. Participants' views were laden with sociological and egocentric components. They often compared plant functions with analogous human functions. Most participants viewed plants as dependent on humans while having societal use. Justifications for views included nominal knowledge of the processes; experiential authoritarian reasoning; and anthropomorphism. We discuss instructional implications in light of the findings. © 2009 Wiley Periodicals, Inc. J Res Sci Teach 46: 791–812, 2009  相似文献   

Acute effects of intense interval training on running mechanics

The aims of this study were to determine if there are significant kinematic changes in running pattern after intense interval workouts, whether duration of recovery affects running kinematics, and whether changes in running economy are related to changes in running kinematics. Seven highly trained male endurance runners (VO 2max = 72.3 +/- 3.3 ml kg -1 min -1 ; mean +/- s) performed three interval running workouts of 10 X 400 m at a speed of 5.94 +/- 0.19 m s -1 (356 +/- 11.2 m min -1 ) with a minimum of 4 days recovery between runs. Recovery of 60, 120 or 180 s between each 400 m repetition was assigned at random. Before and after each workout, running economy and several kinematic variables were measured at speeds of 3.33 and 4.47 m s -1 (200 and 268 m min -1 ). Speed was found to have a significant effect on shank angle, knee velocity and stride length (P ? 0.05). Correlations between changes pre- and post-test for VO 2 (ml kg -1 min -1 ) and several kinematic variables were not significant (P > 0.05) at both speeds. In general, duration of recovery was not found to adversely affect running economy or the kinematic variables assessed, possibly because of intra-individual adaptations to fatigue.  相似文献
