Abstract

Keterampilan komunikasi menggunakan matematika merupakan suatu hal penting dalam proses belajar matematika. Keterampilan ini memungkinkan para murid untuk menyampaikan konsep matematisnya dengan cara penyampaian langsung melalui mulut, tulisan, dan visual. Penelitian ini menggunakan desain penelitian deskriptif kualitatif untuk mengevaluasi kemampuan siswa kelas 3 SD untuk menyelesaikan masalah yang berkaitan dengan materi keliling bangun datar persegi dan persegi panjang. Data dikumpulkan melalui dua metode: tes tertulis yang dilakukan terhadap sepuluh siswa di kelas 3 SD dan wawancara individual yang dilakukan terhadap lima siswa. Tes tertulis bertujuan untuk mengukur kemampuan siswa dalam menyelesaikan masalah keliling bangun datar, sedangkan wawancara menentukan bagaimana siswa memahami konsep keliling dan bagaimana mereka mengkomunikasikannya. Hasil penelitian menunjukkan bahwa sebagian besar siswa dapat dengan mudah mengidentifikasi dan menghitung keliling persegi panjang dan persegi. Namun, beberapa siswa kesulitan menyampaikan proses pemecahan masalah secara tertulis. Penelitian ini memberikan manfaat besar bagi guru dalam mengembangkan strategi pembelajaran yang dapat meningkatkan kemampuan siswa untuk berkomunikasi secara matematis, terutama dalam hal pemecahan masalah matematika

Abstract

This research aims to examine and determine the improvement in problem-solving abilities with the implementation of the PBL learning model assisted by LKPD. This study was conducted at SMP Deli Murni Sukamaju in Class VIII, with sample VIII-1 as the control class and VIII-2 as the experimental class. The type of research used is quasi-experimental research. The instrument used for data collection consists of 7 pre-test questions and 7 post-test questions on problem-solving abilities in the topic of number patterns. Based on the results of the research hypothesis using a two-way ANOVA with N-Gain data, the significant value is > =0.05, so H0 is rejected both overall and based on the students' Initial Mathematical Ability. This means that the improvement in students' problem-solving abilities using the PBL model assisted by LKPD is better overall and based on the students' Initial Mathematical Ability (KAM) than students using the Conventional model. The absence of interaction between learning and KAM, as seen in the significant value of the KAM*Class row with a result of >=0.05, means that the improvement in problem-solving ability occurs entirely due to learning. Continued with the Scheffe test, which showed that the group with low KAM significantly had better improvement compared to the students in the medium and high KAM groups.

Abstract

In this study, researchers will find out the obstacles faced by students when working on trigonometric identity problems based on Watson criteria. The method in research is qualitative description through several conditions, namely data reduction, data presentation, and conclusions. Based on the results of the study, it was found that among the 8 types of Watson error criteria, students made the most errors on several criteria, namely incorrect data, improper procedures, missing data and missing conclusions. This error can occur because students are lacking in mastering the concept of trigonometric identity material, so students often make mistakes from entering data that has been known to the problem, students are unable to apply formulas in solving problems, also students cannot solve the problem until the end. The factors causing the error of class XI students of Tamalabang State Science in solving trigonometric identity problems are students who do not master the basic concepts of trigonometric identity and students do not want to learn to understand the basic concepts of trigonometric identity because students find it difficult to understand, causing students to often make mistakes.
