方老师:听说,上海的课程教材改革,现在已经从开设必修课、选修课、活动课的基础上,进入了一个新的阶段,那就是把课程分为基础型、拓展型和研究型三类,要求学生在打好基础的前提下拓展视野,并从事研究性学习。您能不能向我们介绍一下有关情况特别是研究型学习的情况呢?谢谢。北京市一中学生肖伟5月2日 Teacher Fang: I heard that the reform of curriculum materials in Shanghai has now entered a new phase based on the establishment of compulsory courses, elective courses and activity classes. That is to say, the courses are divided into basic type, extended type and research type III Class, require students to lay a good foundation to expand their horizons, and engage in research study. Could you please tell us about the situation, especially research-based learning? Thank you. Xiao Wei, a middle school student in Beijing, May 2
