浙教版初中数学拓展性课程教材编写特点及改进建议

Researching on the Characteristics of Mathematics Textbook of Enrichment Curriculum in Middle School of Zhejiang Education Press Version

拓展性课程是国内学校课程的重要建设内容之一,教材编写是影响学生拓展性课程"学习机会"的重要因素.研究选取浙教版《义务教育拓展性课程数学新探索》七~九年级上册3本教材,借鉴数学教材探究活动分析框架,从学习进度、内容特征、呈现方式、探究活动特征等方面分析教材编写得失.研究表明,选取的3本拓展性课程教材对基础性课程进行了拓展延伸;教材设计体现"学为中心"理念;多样化拓展课题凸显课程层次性;但活动形式以个人解答为主,突出数学运算与推理.建议在数学拓展性课程中提高对数学基础性知识的应用与整合,加强数学建模素养在课程中的渗透,均衡不同类型拓展活动的比例,设计开展STEAM教育,以提高课程实践性及综合性.

Enrichment curriculum was one of the important contents of curriculum construction, textbook compilation was a important factor that influence students’ "learning opportunities". In this study, mathematics textbook of enrichment curriculum that published by Zhejiang Education Press was chosen as the research object. We analyzed the characteristics of textbook from the learning progress, content features, presentation style and exploration activity features. The results showed the textbook of enrichment curriculum extends the basic curriculum;the textbook design reflects the concept of "centering on learners";diversified enrichment projects highlight the hierarchy of curriculum, but the Individual solutions were the main forms of activity, and highlighting mathematical operations and reasoning. According to these results, we offered some suggestions as follows: Strengthen the application and integration of basic mathematics knowledge;balance the proportion of different types of enrichment activities;development of math enrichment courses based on STEAM concepts.
