The development and investigation of Language activities:Focusing on the skills of logical understandings and expressions

自国家课程标准更新以来，研究者和教师都提出了各种各样的“语言活动”。然而，这些活动并没有很好地系统化。在这项研究中，我专注于培养理解和用逻辑方式表达的语言技能。对语言活动的方法进行了回顾，并指出了两种语言活动的必要性：(1)无论主题如何，都可以实施的活动框架；(2)“日常语言活动”。作为活动框架，提出了以学生讲解为主导的语言活动模式。调查了LASE对数学问题解决和阅读的影响，发现LASE对理解和培养语言技能是有效的。对于“日常语言活动”，开发和提出了模拟工具(“我的词典”和“POSTIT笔记”)。

Since the government's renewal of curriculum guideline, a variety of "Language activities" have been proposed by both researchers and teachers. These activities were, however, not well schematized. In the study, I focused on fostering the language skills to understand and express in logical ways. The methods of Language activities were reviewed, and the review pointed out the needs for two kinds of Language activities: (1) the activity frameworks that could be implemented regardless of the subject, (2) the "everyday language activity". As the activity framework, Language Activity led by Students' Explanations (LASE) was proposed. The effects of LASE on math problem solving and reading was investigated, and found to be effective on understanding and fostering language skills. For the "everyday language activity", analogue tools ("My Dictionary" and "PostIt Note") were developed and proposed.
