摘要
初步研究表明,初二学生对正弦规则的数学解题能力存在一定的不足。影响这一问题的因素之一是教师的学习模式,这种模式仍然是机械的。老师没有把学习与环境或当地文化联系起来。基于此,本研究旨在以有效的民族数学pbl正弦规则为主题,发展HLT。所使用的开发模型是Plomp模型和Gravemeijer and Cobb模型,分为初始调查阶段、产品开发阶段和评估阶段。在本文中,讨论的重点是HLT的发展阶段。使用的数据分析技术是描述性统计和描述性技术。使用的数据收集工具:验证表、观察表、访谈表、问卷调查和现场记录。本研究得出的基于米南卡堡文化PBL细微差别的正弦规则的HLT符合0.771的效度标准,在内容和结构上都具有效度特征。
Hypothetical Learning Trajectory Design of Sinus Rules Based on PBL with Ethnomathematics of Minangkabau Culture
Based on the preliminary research, the tenth-grade students lacked ability in mathematical problem solving of sine rule. One of the factors that influenced this problem was the teacher's learning model, which was still mechanistic. The teacher did not relate between learning and environment or local culture. Based on this, this study aims to develop HLT on the topic of a valid ethnomathematical PBL-based sine rule. The development model used is the Plomp model and the Gravemeijer and Cobb model, which consists of the initial investigation stage, product development stage, and assessment stage. In this article, the discussion is focused on the HLT development stage. The data analysis technique used is descriptive statistics and descriptive techniques. Data collection instruments used: validation sheets, observation sheets, interview sheets, questionnaires, and field notes. This study resulted in the HLT of the sine rule based on PBL nuances of Minangkabau Culture, which met the validity criteria of 0.771 and the characteristics of validity in terms of content and constructs.
