Monolingual, native French-speaking subjects (9- and 11-year-old children and adults) were requested either to talk or write about nine triplets of pictures whose components varied along the pragmatic dimension «new vs. given information». In the first picture in each series, all components were new. In the second and third pictures, one component was replaced each time by a new component, the other components becoming given. The oral execution of the task made the experimenter (the addressee) into a co-producer of the situational discourse produced, whereas the written production situation placed a certain distance between the producer and the addressee. The expression of the contrast between old versus new elements to be described in each situation was studied by examining the use ofarticles (definite andindefinite) andpronouns. The expression of oldness and newness by means of articles was more common in speaking than in writing. In the oral medium, the given/new contrast was marked more and more often as age increased, although this was not true in the writing situation, where the subjects generally used definite articles, even when referring to a new element. Pronouns were used infrequently orally, particularly by 9-year-olds, to express the increasing «oldness» of the elements. The written use of pronouns was extremely rare. Although it was already present orally in older subjects, the tendency to give autonomy to the production associated with each picture (decreasing use of pronouns in favor of nouns) was predominant in the written medium. Maximum explicitness was favored in writing (due to the deferred reception of the production by the addressee), and the marking of elements as new or given was therefore not given priority. The way in which the written and oral production media modulated the choices of the subjects is discussed.  相似文献

Throughout his focus article, Robert Sternberg discusses the theoretical underpinnings and rationale behind his emerging Active Concerned Citizenship and Ethical Leadership (ACCEL) model. In the process, he raises several critically important issues, including the misuse of IQ testing as the major method for identifying gifted students, the need to address real-life problems by focusing on creativity and concerned citizenship, and the potential for principled, ethical leadership to make a real difference in the world now and in the future. The intent of this response article is to pick up on these major themes, extend the conversation, emphasize the necessity for expanding enrichment programming to include marginalized young people for whom the playing field is not level, and help set the stage for wider implementation of the ACCEL framework to enhance identification, instruction, and learning in gifted education.  相似文献

Our research is concerned with teacher’s knowledge, and especially with teacher’s processes of learning, in the classroom, from observing and interacting with students’ work. In the first part of the paper, we outline the theoretical framework of our study and distinguish it from some other perspectives. We argue for the importance of distinguishing a kind of teacher’s knowledge, which we call didactic knowledge. In this paper, we concentrate on a subcategory of this knowledge, namely observational didactic knowledge, which grows from teacher’s observation and reflection upon students’ mathematical activity in the classroom. In modeling the processes of evolution of this particular knowledge in teachers, we are inspired, among others, by some general aspects of the theory of didactic situations. In the second part of the paper, the model is applied in two case studies of teachers conducting ordinary lessons. In conclusion, we will discuss what seems to be taken into account by teachers as they observe students’ activity, and how in-service teacher training can play a role in modifying their knowledge about students’ ways of dealing with mathematical problems.  相似文献

The purpose of this study was to examine the ability of two educational leadership university programmes to improve the cognitive agility of their graduates. The research looked to discover whether the aspiring principals exited the programmes with an increased ability to employ cognitive agility – the ability to use the multiple thinking skills of systems thinking, reflecting, and reframing – when engaged in their professional work and solving problems. Both Masters programmes were in School Leadership, offered through the same university department and following the same core curriculum leading to Level 1 educational leadership certification. The results indicate that of the two programmes studied, the Principal Rapid Orientation and Preparation in Educational Leadership (PROPEL) programme, designed to prepare leaders for turnaround schools, produced more cognitively agile graduates than the traditional Master’s programme. The mediating variables of participants’ years of experience and budget responsibility increased the level of cognitive agility of both programme’s graduates.  相似文献

This study aimed to test a four-wave sequential mediation model linking mother–child attachment to children's school readiness through child executive functioning (EF) and prosociality in toddlerhood and the preschool years. Mother–child attachment security was assessed when children (= 255) were aged 15 months and 2 years, child EF at age 2, prosocial behavior at age 4, and finally cognitive school readiness in kindergarten (age 6). The results revealed three indirect pathways linking attachment to school readiness: one through EF only, one through prosocial behavior only, and a last pathway involving both EF and prosocial behavior serially. These findings suggest that secure attachment may equip children with both cognitive and social skills that are instrumental to their preparedness for school.  相似文献

In order to explore the possible confounding effects of age, race, sex, and socioeconomic status on developmental outcomes of prenatal cocaine exposure, two matched samples of preschoolers (20 children with cocaine/polydrug in utero exposure and 20 children with no prenatal drug exposure) were compared on the Stanford-Binet: 4th ed. (S-B: 4th ed.), Social Skills Rating System, Vineland Adaptive Behavior Scale—Survey Form, Preschool Language Scale: 3rd ed. (PLS: 3rd ed.), and the Child Behavior Checklist. None of the 40 children had attended or were currently enrolled in preschool programs. Both groups had scores approximately one standard deviation below the expected mean in social skills, auditory comprehension, and expressive language. Likewise, externalizing behavior difficulties were approximately one standard deviation above the mean for both groups. Results suggest in utero drug exposure had no independent impact on cognitive, social, language, and behavioral developmental outcomes when the confounding variables of age, ethnicity, gender, and SES were controlled. © 1997 John Wiley & Sons, Inc.  相似文献

In keeping with proposals emphasizing the role of early experience in infant brain development, this study investigated the prospective links between quality of parent–infant interactions and subsequent child executive functioning (EF), including working memory, impulse control, and set shifting. Maternal sensitivity, mind-mindedness and autonomy support were assessed when children were 12 to 15 months old ( N  =   80). Child EF was assessed at 18 and 26 months. All three parenting dimensions were found to relate to child EF. Autonomy support was the strongest predictor of EF at each age, independent of general cognitive ability and maternal education. These findings add to previous results on child stress-response systems in suggesting that parent–child relationships may play an important role in children's developing self-regulatory capacities.  相似文献

This study investigated the status of phonological representations in French dyslexic children (DY) compared with reading level- (RL) and chronological age-matched (CA) controls. We focused on the syllable’s role and on the impact of French linguistic features. In Experiment 1, we assessed oral discrimination abilities of pairs of syllables that varied as a function of voicing, mode or place of articulation, or syllable structure. Results suggest that DY children underperform controls with a ‘speed-accuracy’ deficit. However, DY children exhibit some similar processing than those highlighted in controls. As in CA and RL controls, DY children have difficulties in processing two sounds that only differ in voicing, and preferentially process obstruent rather than fricative sounds, and more efficiently process CV than CCV syllables. In Experiment 2, we used a modified version of the Colé, Magnan, and Grainger's (Applied Psycholinguistics 20:507–532, 1999) paradigm. Results show that DY children underperform CA controls but outperform RL controls. However, as in CA and RL controls, data reveal that DY children are able to use phonological procedures influenced by initial syllable frequency. Thus, DY children process syllabically high-frequency syllables but phonemically process low-frequency syllables. They also exhibit lexical and syllable frequency effects. Consequently, results provide evidence that DY children performances can be accounted for by laborious phonological syllable-based procedures and also degraded phonological representations.  相似文献
