中日关系新格局与日本对华战略

世纪之交,中日两国的实力都处在上升期.在日本以超级经济大国地位加速实现政治大国目标和中国日益崛起的进程中,中日之间“强强型”关系的新格局正在形成.面对新局面,日本逐步调整对华战略,在继续与中国进行多方合作的同时,开始视中国为战略对手,多方面对中国进行牵制与防范.在此情况下,中国也必须重新审视中日关系,采取妥善对策.     

Folklore epistemology: how does traditional folklore contribute to children’s thinking and concept development?

This research utilised a ‘stimulated recall’ methodology [Calderhead, J. 1981. “Stimulated Recall: A Method for Research on Teaching.” British Journal of Educational Psychology 51: 211–217] to explore the potential of African folklore, specifically Ghanaian folk stories in the development of children’s reflective thinking about social life. The research was based on Ghanaian folklore for children, which is popularly known as ‘By the Fireside Stories’, encapsulated traditionally as Anansesem or Spider stories among the Akan of Ghana. Data were collected through storytelling to a group of children and inviting them to recall their concurrent thinking during and after the storytelling. The children’s cognitive recall processes were stimulated by questions and story character dramatisation recorded on a digital video recorder and played back to the children. Findings showed major contributions to children’s learning and development related to imagination, concept formation and thinking, and beyond the self in social relationship. This paper draws attention to how traditional oral storytelling can be an important part of early childhood education to develop children’s reflective thinking about social life.     

Shaping global teacher identity in a short-term mobility programme

This article explores the shaping of Australian and Malaysian pre-service teachers’ possible selves in a short-term mobility programme. With the theory of possible selves, individuals imagine who they will become based on their past and current selves. The focus of the research was on pre-service teachers’ possible selves as global and culturally responsive teachers. The experiential learning through participation in the programme allowed participants to consider their future possible selves as teachers with a deeper understanding of diverse learners’ needs and how they might strive to address these needs in their own classrooms. The scaffolding of reflections in the programme encouraged the pre-service teachers to take on multiple perspectives, to step outside their comfort zones and in many ways to see the world from different eyes. The research found that through experiential learning in the short-term mobility programme both the Australian and Malaysian pre-service teachers gained in positioning their cultural selves currently and as future teachers, suggesting that there is merit in utilising the theory of possible selves in future research in the area of shaping teacher identity.

Face-to-face versus computer-mediated discussion of teaching cases: Impacts on preservice teachers’ engagement, critical analyses, and self-efficacy

Two frequently-used discussion protocols were investigated as part of a program to implement teaching cases in undergraduate educational psychology classes designed for preservice teachers. One protocol involved synchronous face-to-face (FTF) discussion of teaching cases, which occurred in class after students had individually completed written case analyses as homework outside of class. The other was asynchronous computer-mediated (CM) discussion taking place outside of class, simultaneous to students’ completion of their written case analyses. Six class offerings of an undergraduate child development course taught by two instructors (three classes by each instructor) were randomly assigned within instructor in a quasi-experimental design to one of the three discussion conditions: FTF, CM, or no discussion of the cases across the semester. Findings indicated that both CM and FTF discussion conditions were associated with positive outcomes relative to the control condition. Both CM and FTF discussion related to higher cognitive–affective engagement with the cases than the control condition; and the CM discussion condition was associated with higher cognitive–affective engagement than FTF discussion. In contrast, FTF discussion, but not CM discussion, was associated with higher-than-control-condition case analysis ability at the end of the semester. Potential explanations for these findings and directions for future research are discussed.     

Authorship analysis of specialized vs diversified research output

The present work investigates the relations between amplitude and type of collaboration (intramural, extramural domestic or international) and output of specialized versus diversified research. By specialized or diversified research, we mean within or beyond the author’s dominant research topic. The field of observation is the scientific production over five years from about 23,500 academics. The analyses are conducted at the aggregate and disciplinary level. The results lead to the conclusion that in general, the output of diversified research is no more frequently the fruit of collaboration than is specialized research. At the level of the particular collaboration types, international collaborations weakly underlie the specialized kind of research output; on the contrary, extramural domestic and intramural collaborations are weakly associated with diversified research. While the weakness of association remains, exceptions are observed at the level of the individual disciplines.
