Development of Curriculum on Mathematical Communication Using Information Technology

本研究的目的是开发和评估初中生使用资讯通讯科技培养数学写作技巧和态度的课程。为了达到这一目的，我们讨论了数学写作的意义和意义，并对数学写作活动的特点进行了思考。接下来，我们回顾了关于学科类活动的实践和课程的文章，并从中提取了优点。我们利用在复习实践中发现的优点，制作了数学学科的网络公告栏。我们开发了课程，让学生探索图形、模式和设计，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“自动成形”功能，以便他们可以轻松地使用重复的相同图形制作图案。我们在一所公立初中用这个课程和网络公告板观察了一年的课程。两个本科生和一个初中老师在校外评论学生的作文。我们观察了一些重要的课程，录制了录像带，分析了学生的书面描述，录制了录像带，并进行了问卷调查。最后，我们结合各种数据，调查并得出结论，课程目标和公告栏系统对技能和态度有显著影响。

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.
