国家教育部在最近颁发的《基础教育课程改革纲要(试行)》中,倡导“研究性学习”.“研究”一词,听起来似乎是科学家或研究员们专用的.其实不然,美国学生从小学时就开始写研究论文了.“研究”,并不是高不可攀的,不是专家学者们才可以做的.中学生研究的问题,可新可旧(可以是前人曾研究过的).可大可小,关键是在研究过程中学会独立思考,学会合作交流.学会研究方法——提出问题、收集、整理资料,提出设想、方法,解决问题乃至引申、拓广. 本刊从本期起,将陆续提出一些研究性课题,与读者共同探讨.也希望读者把自己的研究课题和探索的过程、結果、心得告诉本刊.我们将为您提供展示数学才华的舞台. The Ministry of Education in the recently issued “Outline for Basic Education Curriculum Reform (Trial)” promotes “research learning”. The term “research” sounds as if it is dedicated to scientists or researchers. Actually, the American students are from elementary school. He began to write research papers. “Research” is not unattainable. It cannot be done by experts and scholars. The problem of middle school students’ research can be new and old (it can be studied by previous people). The key is to learn to think independently and learn to cooperate and communicate in the process of research. Learn to study methods - ask questions, collect, collate data, propose ideas, methods, solve problems and even extend and broaden. From this issue, the journal will Several research topics have been proposed one after another to discuss with readers. We also hope that readers will tell the journal about their research topics and their exploration process, results, and experiences. We will provide you with a stage to demonstrate your mathematical talents.
