Development of Curriculum on Mathematical Communication Using Information Technology

我们的研究项目的目的是开发和评估初中学生利用信息和通信技术培养数学写作技能和态度的课程。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，我们回顾了关于科学这门学科中类似活动的实践和课程的文章，并提取了好的观点。我们为数学学科准备了网络公告栏，利用从回顾的实践中发现的优点。我们开发了课程，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来制作图案。我们使用这个课程和网络公告栏在一所公立初中观察了一年的课程。两名本科生，一名校外的初中老师对学生的作文进行了点评。我们观察了一些重要的课程，录制了录像带，分析了对学生的书面描述，录制了录像带和调查问卷。最后，我们结合各种数据，调查得出课程目标和公告栏制度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.
