项目摘要

The aim of our research project is to develop and evaluate curriculum for junior high school students for fostering skills and attitudes of mathematical writing using information and communication technology. In order to accomplish the aim, we discussed about the meanings and significance of writing about mathematics, and considered about characteristics of the activities of mathematical writing. Next, we reviewed articles on practices and curriculum of similar activities in the subject science and extracted good points. We prepared web bulletin board for the subject mathematics that make use of the discovered good points extracted from reviewed practices. We developed curriculum in which students explore about figures, patterns and design, reflect on their own activities, and write about their own findings, consideration, and impressions. In this curriculum, students use the function of 'auto-shape' in spread sheet software so that they can easily make patterns using repeated same figures. We observed a year-long lesson at a public junior high school using this curriculum and web bulletin board. Two undergraduate students a junior high school teacher outside the school have commented the students' writing. We have observed some important lessons, recorded video tapes, and analyzed written descriptions of students, recorded video tapes, and questionnaires. Finally, we combined various data, investigated and concluded that the aim of the curriculum and the bulletin board system had significant effects on skills and attitudes.

我们研究项目的目的是开发和评估初中生使用信息和通信技术培养数学写作技能和态度的课程。为了实现这一目标，我们探讨了数学写作的意义和意义，思考了数学写作活动的特点。接下来，我们回顾了学科科学中类似活动的实践和课程的文章，并提取了优点。我们为学科数学准备了网络公告板，利用从审查实践中提取的发现的优点。我们开发的课程让学生探索图形、图案和设计，反思自己的活动，并写下自己的发现、思考和印象。在本课程中，学生使用电子表格软件中的“自动形状”功能，以便他们可以轻松地使用重复的相同图形制作图案。我们使用该课程和网络公告板在一所公立初中观察了为期一年的课程。两名本科生、一名校外初中老师对学生的写作进行了点评。我们观摩了一些重要的课程，录制了录像带，并对学生的书面描述、录制的录像带和问卷进行了分析。最后，我们结合各种数据，调查并得出结论：课程目标和公告牌系统对技能和态度有显着影响。
