A Study on Japanese Acquisition, Education and Support in the Multilingual Environments

利用我们小组成立的日本多种语言协会，我们在日本和海外进行了一些研究并报道了一些情况。作为研究的延伸，我们还举办了一次多语种同步学习支持国际研讨会。以下是我们的研究总结：1.从不同的研究观点，如(1)一人一种语言和一种环境-或语言假说，(2)主导语言和思维语言，(3)转换对多语种人语言感知的影响，(4)语言新近性和语言选择，(5)接触情景中的语言使用，(6)多重身份；(7)处所格标记；(8)时体。在我们举办的一次国际研讨会上，讨论和总结了韩国、中国和日本的多语言同步学习的现状和计划。这样的项目可以成为新的日本教师教育项目的一部分。
