The existence of dyslexia without severe literacy problems     

T.?R.?MilesEmail author  T.?J.?Wheeler  M.?N.?Haslum 《Annals of dyslexia》2003,53(1):340-354

This paper is concerned with those who display positive indicators on tests for dyslexia but seemingly do not have any severe literacy problems. A case study is presented by way of illustration. On the basis of data from the British Births Cohort Study (12,905 10-year-old children), it was found that some seemingly normal achievers who showed signs of dyslexia (N=422) obtained different results on five measures associated with dyslexia than did other normal achievers without such signs (N=4,998). The measures used were: underachievement at word recognition; and underachievement at spelling, reading comprehension, pseudoword reading, and mathematics. The proportion of boys to girls in the groups was also noted. It is suggested that these were cases of mild dyslexia, who, on the basis simply of reading and spelling tests, might escape detection. The consequences for the concept of dyslexia are discussed, and it is suggested that the needs of dyslexics with only mild literacy problems should not be overlooked.  相似文献   

Learning in multiple contexts: are there intra-, cross- and transcontextual effects on the learner’s motivation and help seeking?

In Germany, Austria and Switzerland, the majority of 15?C19-year olds follow vocational education programmes within a dual-track system, spending most of their time in a company and going to school only 1?day each week. With their separate aims, content and sociological organisation, the company and the school can be considered as two distinct contexts within which apprentices have to acquire the various skills and competencies of their future occupation. In this paper, the development of apprentices?? learning intentions and motivation to learn, subjective competence, perceived utility of what is learned and estimated learning place attractiveness (study 1) as well as their readiness to seek help in these different contexts over the year of training (study 2) is analysed using both longitudinal and cross-sectional data. The findings show significant differences in apprentices?? motivation, their beliefs and their readiness to seek help in the different contexts throughout the training. Moderate (cross-different contexts, same time) as well as transcontextual (different contexts, different times) influences can also be seen. These results emphasise the importance of a careful delimitation of contexts when studying the impact of contextual factors on learners?? motivation and behaviours; they also suggest that motivation within one of these contexts can indirectly affect the learner??s motivation within another of these contexts. It is therefore likely that, by using these various dynamics appropriately, educators might temporarily sustain learners?? motivation in an unappreciated context by having recourse to a better accepted one.  相似文献   

The impact of friendship on synchronous collaborative retrieval tasks in the primary school     

Jérôme Dinet  Robin Vivian 《British journal of educational technology : journal of the Council for Educational Technology》2012,43(3):439-447

Two experiments aim at describing the impact of friendship during a synchronous collaborative information retrieval (SCIR) with young pupils (recruited in Grade 3). In the first study, 68 pupils were asked to look for 13 answers in one of the three following conditions: on an individual basis (condition “Single”), as part of a designed duo with social friendship (condition “Affinity +”), or as part of a designed duo without social friendship (condition “Affinity ?”). In the second experiment, we investigated more precisely the impact of friendship on verbal interactions between partners. Main results obtained in these two experiments are the following: (1) pairs retrieved effectively more answers, more correct answers and were more efficient than singles; (2) pairs composed of pupils without social friendship retrieved more answers, more correct answers and were more efficient than pairs composed by friends; (3) pairs composed of friends produced significantly more irrelevant queries; and (4) pairs composed of friends produced more verbalisations related to conflicts, while pairs composed of pupils without social friendship are engaged in a great deal of consensus seeking. Finally, educational implications are discussed.  相似文献

A description of a mother's play guidance for her child with autism in the process of playing by the rules     

Meral Çilem Ökcün  Nur Akçin 《Journal of Research in Special Educational Needs》2012,12(2):96-106

The purpose of this study is to describe the strategies used by a mother with a child with autism during games activities with peers to provide the child with social skills. The research method of this study is ‘a qualitative single‐subject case study’. The participants in this research are a mother and her 9‐year‐old child with autism, one brother and three typically developing peers. The research data were collected through field notes, interviews, audio and videotape recordings during natural interactions between the mother and her child. The strategies the mother used were analysed using video records during games activities in a natural park. The interactions of the mother with her child were examined in the context of a hide‐and‐seek game. Micro‐ethnographic‐analysis techniques were used in the analysis of the video records. According to the research data, it was found that the mother with a child with autism made extensive use of 13 different verbal strategies and seven different non‐verbal strategies. It was observed that the mother guided her child and the group during the hide‐and‐seek game, arranged the environment of the games, carried out routine activities both at the beginning and at the end of the games and arranged the games in accordance with the abilities and preferences of the child. These applications bear a resemblance to the model of integrated game groups. As a result, the data from the present research reveal that a mother having a child with autism acts as a guide during the games and uses verbal and non‐verbal interaction strategies in this guidance process and by doing so contributes to the process of participation in the games by the child with autism and in the child's social interaction with his peers.  相似文献   

Critical Issues in Teaching a Multicultural Counseling Course     

Eunju Yoon  Gihane Jérémie-Brink  Kathleen Kordesh 《International journal for the advancement of counseling》2014,36(4):359-371

A Multicultural Counseling course (MCC) brings unique challenges and rewards to both instructors and students. Given its unique challenges, the process of teaching a MCC is as important as, or even more important than, the content. Drawing from extant literature and the authors’ experiences, this paper discusses such topics as what to teach, how to teach, classroom dynamics, instructors’ issues, and students’ issues to provide a concise, practical, and comprehensive framework for teaching such difficult but essential courses.  相似文献   

Convergence of Visions     

Thérèse Paquet-Sévigny 《International Information and Library Review》2013,45(3-4):447-454

The right for everyone to access “the promised land” of the InfoSociety is widely recognized. The “wiring of the universe” is now technically and financially possible. One should do it quickly in the respect of human values and rights, freedom of opinion, transparency and cultural diversity. However, in the context of communication developments in 1997, it is a multifacet issue of concern to all the countries. The cyberspace era brings many new challenges to the communications' academic curricula, professional practices, media owners and the research and development (R&D) of industries across the world. The emerging virtual communities change social and political relationships, as well as the job market well beyond national and linguistic boundaries. The paper examines the minimal conditions needed for this open process to take place with the participation of all players and the possible role of ORBICOM, the network of UNESCO Chairs in Communication.  相似文献   

A Longitudinal Study of the Social Adjustment of Mentally Retarded Adults in Sweden. A Discussion of Methodological Problems and Preliminary Results     

Rikard Palmér 《Scandinavian Journal of Educational Research》2013,57(4):197-209

Palmér, R. 1982. A Longitudinal Study of the Social Adjustment of Mentally Retarded Adults in Sweden. A Discussion of Methodological Problems and Preliminary Results. Scandinavian Journal of Research 26, 197‐209. In connection with an interdisciplinary research project, 1966‐1971, a differential psychological survey of about one hundred mentally retarded young people in the 18‐25 age‐group was carried out. About ten years later a follow‐up investigation began. Initially the central concern was to clarify the meaning of social adjustment in middle age. Essential components of this variable include objectively observable facts such as work and living situation, but also adaptive behaviour and the individual's perception of himself and his situation. Methodological problems are examined in broader theoretical perspective. One conclusion is that we should seek access to individual perceptions and experiences ‐ of which handicap awareness is a vital component ‐ via relatively unstructured conversations and interviews. This part of the study can then be developed into a consciously hermeneutic approach. Preliminary results of analysis are discussed.  相似文献   

Preservice Science Teachers’ Efficacy Regarding a Socioscientific Issue: A Belief System Approach     

Ahmet Kılınç  Tezcan Kartal  Barış Eroğlu  Ümit Demiral  Özlem Afacan  Dilber Polat  Mutlu P. Demirci Guler  Özkan Görgülü 《Research in Science Education》2013,43(6):2455-2475

The aim of the present study was to understand the nature of teaching efficacy beliefs related to a socioscientific issue (SSI). We investigated Turkish preservice science teachers’ teaching efficacy beliefs about genetically modified (GM) foods using a belief system approach. We assumed that preservice teachers’ beliefs about GM foods (content knowledge, risk perceptions, moral beliefs, and religious beliefs) and their teaching efficacy beliefs about this topic constitute a belief system, and these beliefs are interrelated due to core educational beliefs. We used an exploratory mixed design to test this model. We developed and administered specific questionnaires to probe the belief system model. The sample for the quantitative part of this study included 441 preservice science teachers from eight universities. We randomly selected eight participants in this group for follow-up interviews. The results showed that preservice science teachers held moderately high teaching efficacy beliefs. Learning and teaching experiences, communication skills, vicarious experiences, emotional states, and interest in the topic were sources of this efficacy. In addition, content knowledge and risk perceptions were predictors of teaching efficacy. We believe that epistemologies based on traditional teaching and the values attached to science teaching are the core beliefs that affect the relationship between predictor variables and teaching efficacy.  相似文献
