This longitudinal study investigated the effects of maternal emotional health concerns, on infants’ home language environment, vocalization quantity, and expressive language skills. Mothers and their infants (at 6 and 12 months; 21 mothers with depression and or anxiety and 21 controls) provided day-long home-language recordings. Compared with controls, risk group recordings contained fewer mother–infant conversational turns and infant vocalizations, but daily number of adult word counts showed no group difference. Furthermore, conversational turns and infant vocalizations were stronger predictors of infants’ 18-month vocabulary size than depression and anxiety measures. However, anxiety levels moderated the effect of conversational turns on vocabulary size. These results suggest that variability in mothers’ emotional health influences infants’ language environment and later language ability. 相似文献

ABSTRACTThis study examines academic outcomes for university students engaged in a supplemental peer learning program in a selective institution. Using a matched sample of 1266 students, half enrolled in the supplemental program and half not enrolled, we find that participating students on average earned higher grades in linked courses. Using a subsample of students in a chemistry course sequence, we find program participants were more likely to remain in the sequence than non-participants, and that the impact was greater for students with lower levels of preparation. 相似文献

The article explores the long‐term effectiveness of in‐service teacher training courses for English as a Foreign Language (EFL) teachers in the Greek educational context. It presents the results of a questionnaire designed and issued to teacher‐trainees a year after the completion of 60‐hour courses. The questionnaire assessed, among others, (a) teacher trainees' beliefs regarding the relevance of the knowledge acquired to their individual needs, (b) the extent to which they used the materials provided in the course, and (c) the usefulness of the subjects offered. The data are discussed in relation to strategies for optimising teacher training services and implications are drawn for the implementation of change in a broader educational context. A ‘cooperative model' is proposed for the promotion of change involving active cooperation between all agents involved in the educational process and necessitating top‐down and bottom‐up cooperation. 相似文献

对20世纪30年代新文学史的编纂和对新文学作品的选编,需要与当时的社会和文化境况,特别是与当时的文化争论紧密联系起来.重读这些资料,有助于我们今天对当时文化界境况的了解,而且也可以重温当时对新文学的评价,从中可见五四运动的一些主要人物再三重申并肯定五四理想,同时也表现出他们的一些不自信和担心.他们反思到:他们生命中的一段历程结束了,与之诞生的文学也行将告一段落.总之,可以推想:20世纪30年代新文学史的编纂和新文学作品的选辑,并不是五四全盛时期的硕果,而是人们对轰轰烈烈的五四运动的深切留恋,<中国新文学大系>尤其可以算是为了已结束的文化时代,也为了自己一代人所作出的贡献而建立的一座纪念碑. 相似文献

Jigsaw puzzles are ubiquitous developmental toys in Western societies, used here to examine the development of metarepresentation. For jigsaw puzzles this entails understanding that individual pieces, when assembled, produce a picture. In Experiment 1, 3- to 5-year-olds (N = 117) completed jigsaw puzzles that were normal, had no picture, or comprised noninterlocking rectangular pieces. Pictorial puzzle completion was associated with mental and graphical metarepresentational task performance. Guide pictures of completed pictorial puzzles were not useful. In Experiment 2, 3- to 4-year-olds (N = 52) completed a simplified task, to choose the correct final piece. Guide-use associated with age and specifically graphical metarepresentation performance. We conclude that the pragmatically natural measure of jigsaw puzzle completion ability demonstrates general and pictorial metarepresentational development at 4 years. 相似文献

The home literacy environment is a well-established predictor of children’s language and literacy development. We investigated whether formal, informal, and indirect measures of the home literacy environment predict children’s reading and language skills once maternal language abilities are taken into account. Data come from a longitudinal study of children at high risk of dyslexia (N = 251) followed from preschool years. Latent factors describing maternal language were significant predictors of storybook exposure but not of direct literacy instruction. Maternal language and phonological skills respectively predicted children’s language and reading/spelling skills. However, after accounting for variations in maternal language, storybook exposure was not a significant predictor of children’s outcomes. In contrast, direct literacy instruction remained a predictor of children’s reading/spelling skills. We argue that the relationship between early informal home literacy activities and children’s language and reading skills is largely accounted for by maternal skills and may reflect genetic influences. 相似文献

Students’ Mental Models of the Internet and Their Didactical Exploitation in Informatics Education 总被引:1,自引:0,他引:1
The Internet constitutes a relatively new teaching subject for the Informatics curriculum. Within secondary education, students should develop an understanding of basic Internet concepts as well as Internet skills. For the attainment of these goals it is necessary that they develop adequate mental models of the Internet. That development should be based on the assessment of their initial mental models of the Internet. The purpose of this study was the investigation of the mental models that high school students form of the Internet in the beginning of the Informatics curriculum. The study involved 340 Greek high school students who completed a written questionnaire and a drawing task. The results suggest that students form simplistic, utilitarian rather than structural mental models of the Internet, which would provide them with an adequate explanatory system of what the Internet actually is and the processes underlying its use. The students’ mental models also involve particular misconceptions. The didactical implications of the findings for Informatics education at high school level are considered. 相似文献
