摘要

学生在学习数字模式材料时需要具备良好的数学推理能力。通过PMRI方法和协作学习使用视频媒体可以应用于学习活动中,以获得良好的数学推理技能。本研究旨在探讨八年级学生在采用PMRI方法的视频媒体学习过程和合作学习数字模式材料后的数学推理能力。本研究采用描述性研究。研究对象为八年级学生。A, Srijaya Negara Palembang SMP, 39名学生中有25名学生(12名男性和13名女性)。数据收集技术包括观察、两道试题的笔试和访谈。数据分析技术是描述性的。本研究获得的结果是学生在使用PMRI方法的视频媒体学习过程中以及在八年级数字模式材料上的协作学习后的数学推理能力。SMP Srijaya Negara Palembang的学生表现良好,平均得分为68.89。出现最多的指标是“提出猜想”,而出现最少的指标是“得出结论”。通过PMRI方法使用视频媒体,在学习过程中进行协作学习,可以使学生具备良好的数学推理能力。

Students’ mathematical reasoning skills on number pattern using PMRI and collaborative learning approach
Students need to have good mathematical reasoning skills when learning number pattern material. The use of video media through the PMRI approach and collaborative learning can be applied in learning activities to have good mathematical reasoning skills. This study aims to determine mathematical reasoning skills after implementing the learning process using video media with the PMRI approach and collaborative learning on number pattern material for class VIII students. This research uses a descriptive type of research. The research subjects were students of class VIII.A, SMP Srijaya Negara Palembang, with 25 students (12 males and 13 females) out of a total of 39 students. Data collection techniques are observation, a written test consisting of two test questions, and interviews. The data analysis technique is descriptive. The results obtained from this study are the students' mathematical reasoning skills after the learning process using video media with the PMRI approach and collaborative learning on the number pattern material of grade VIII.A students of SMP Srijaya Negara Palembang are good, with an average value of 68.89. The indicator that appears the most is "submit a conjecture," while the indicator that appears the least is "draw a conclusion." Using video media through the PMRI approach and collaborative learning during learning can make students have good mathematical reasoning skills.
