The development of referential communication: Improving message accuracy by coordinating private speech with peer questioning

In this study, we examine the development of referential communicative regulation, incorporating the Vygotskian notion of private speech. From this perspective, private speech may serve a regulatory role when the child speaker is focused on what to say when speaking to others. In a longitudinal study carried out with 10 pairs of children with a mean age of 4.5, 6.5, and 8.5 years, we analyzed the relationship between the capacity of the child in the speaker role to modify messages, increasing their informative quality, the presence of private speech embedded in the messages, and the emergence of prior questions by the child in the listener role aimed at clarifying some aspect of the message. We found that the number of modified messages, the mean frequency of private speech in the messages, and the number of peer's questions all increase with age. Only in the case of the modified messages by the speaker did we find a triple interaction among age, use of private speech, and the presence of peer's questions. At 8.5 years, the presence of peer's questions and subsequent use of private speech appeared together for the majority of the modified messages. This was not the case at the ages 4.5 or 6.5. In line with Vygotsky's theses, private speech would play an important role to allow communicators to reflect on the quality of their communicative utterances, and to modify and improve them accordingly. In this process, the capacity to improve message accuracy by coordinating private speech with peer questioning clearly emerges with age.

—美国画家阿特眼中的古城衢州水墨丹青寄乡情简

阔别家乡十多年的女艺术家古仪带着这几年来创作的一百幅作品,来杭州举办大型个人画展。 古仪（原名励国仪）,是著名国画大师潘天寿的儿媳,中央美术学院院长潘公凯的夫人。她少年时代与潘公凯同时求学于浙江美术学院附中,附中生活开始了她对艺术之梦的探索和追求。尽管因“文革”她的求学生涯充满着艰辛和挫折,但是回忆起附中生活,她仍十分愉快地说：“虽然那时没有很多可看的画册,我们仍从学校图书馆找出前苏联列宾、苏里科夫的画册,进行翻拍,装订成册供自己学习。图片是用潘公凯手工制作的放大机放的,放得十分清晰,比照相馆里放得还好。”“文革”结束后,古仪在出版社任美术编辑,创作了大量的儿童连环画和书籍插图,其中有些作品在瑞士、法国、伊朗等国获奖。

基于APP的公共档案馆可提供的手机移动服务构想

随着移动互联网的普及和智能手机的不断发展进步,手机APP因其迅速、便于利用等特点得到了广泛的传播和利用。不仅商业APP,也有越来越多的政府部门开始开发并使用APP。同时,在档案学研究领域,档案数字化的进程也在进行中。本文以此为背景,首先简单介绍了APP的概念,之后提出公共档案馆可开发APP手机服务的基础,接下来具体叙述了关于公共档案馆可以开发哪些手机服务及这些服务的具体内容,从而进一步发挥公共档案馆不仅作为政府部门,还能作为公共服务机构发挥社会作用的理论构想。     

Children’s rough and tumble play: perspectives of teachers in northern Canadian Indigenous communities

Ten teachers in kindergarten and grade one classrooms in remote northern Canadian Ojibway communities, and two consultants from a First Nations Student Success Program participated in focus group discussions about the place of rough and tumble and superhero play, and teachers’ roles in preventing relational and physically aggressive play in school. This paper reports on issues related to sociocultural influences on perceptions of play involving objects to which Indigenous children assign implicit roles as guns, and teachers’ concerns about external perceptions of teachers’ roles vis-à-vis rough and tumble play in school. Implications for teacher practice and for teacher education include establishing boundaries and negotiating rules and consequences with students, and teaching problem-solving approaches. Teachers’ expressed need for exposure to research on rough and tumble play in teacher education and professional development initiatives is consistent with the findings of previous research. This study provides perspectives from teachers in a non-mainstream teaching context on a controversial topic with mixed views coming from researchers and media reports.
