AbstractWe examined the progress made by 132 six-year-old French-speaking children in their preliteracy skills during four kinds of interventions. Three of these interventions concerned invented spelling, where the children tried to spell words. In the first condition, they were encouraged to reflect on conventional spellings. In the second condition, they reflected on spellings that were slightly more complex than theirs, while in the third condition, they reflected on increasingly complex spellings that eventually led to the conventional spellings. The fourth condition (control) consisted of phonological training. We assessed the children’s phonological awareness, letter knowledge, spelling, and decoding skills, controlling for vocabulary and nonverbal cognitive ability. Posttest results indicated progress in each condition. The greatest progress was observed in the second condition for decoding, spelling, letter-name knowledge and syllable awareness, and in the control condition for phoneme awareness. Overall, results showed that all kinds of interventions led to very similar levels of progress, but that improvements were greater for interventions that focused on the children’s initial invented spellings - in other words, when they adopted a Vygotskian perspective. 相似文献

This review highlights two areas of particular interest in the study of social learning in fowl. First, the role of social
learning in the development of feeding and foraging behavior in young chicks and older birds is described. The role of the
hen as a demonstrator and possible teacher is considered, and the subsequent social influence of brood mates and other companions
on food avoidance and food preference learning is discussed. Second, the way in which work on domestic fowl has contributed
to an understanding of the importance of directed social learning is examined. The well-characterized hierarchical social
organization of small chicken flocks has been used to design studies which demonstrate that the probability of social transmission
is strongly influenced by social relationships between birds. The practical implications of understanding the role of social
learning in the spread of injurious behaviors in this economically important species are briefly considered. 相似文献

This mixed methods study explores a service-learning experience embedded in a social foundations course in a teacher education program. The authors differentiate learning outcomes for social justice and charity service-learning, and utilize this framework to examine whether the service-learning experience fosters a social justice perspective. The findings demonstrate that while the experience did foster social justice perspectives for some students, the data also reflect evidence of learning outcomes that align with charity service-learning. 相似文献

This article contains a review of recent research on the topic of language development in an educational research perspective. The contribution is focussed on research which was carried out in the German education system. The starting point of such research was the insight that mastery of a language is of core importance for educational success as well as for participation in a society. The research which is presented in this review article strives to identify factors that are relevant for the development of different language abilities during an education biography. The article starts with an overview of international and national research traditions which build the ground for the investigation of language development in an educational research perspective. A second part of the article deals with research projects that aimed to unveil factors which are influential for differential language development during a school career. In the third part of the article, an outlook on recent research is presented which deals with the question how language development can be fostered and supported by educational institutions. In Germany, such projects are just beginning. They mainly derive from the evaluation of model projects or other practical experiments; only very few experimental intervention studies have been carried out. 相似文献
