Tujuan penelitian ini adalah untuk menghasilkan lintasan belajar dalam membantu siswa pada pembelajaran garis dan sudut dengan konteks pagar buluh. Metode yang digunakan dalam penelitian ini adalah design research type validation studies dengan mengujikan 6 siswa sebelum melibatkan 34 siswa kelas VII MTs Negeri Jambat Balo Pagaralam dengan dugaan lintasan belajar atau Hypothetical Learning Trajectory (HLT). Kemudian HLT tersebut dikembangkan dan seperangkat aktivitas diterapkan untuk memperoleh pemahaman yang lebih baik tentang bagaimana mengembangkan pemahaman materi garis dan sudut melalui tiga tahap, yaitu preliminary design, the design experiment, dan retrospective analysis. Penelitian yang dilakukan menghasilkan learning trajectory yang terdiri dari serangkaian proses pembelajaran dalam tiga aktivitas yaitu membuat pagar buluh, menyelesaikan masalah pada materi garis, dan menyelesaikan masalah pada materi sudut. Hasil penelitian menunjukkan bahwa dengan menggunakan konteks pagar buluh siswa dapat memahami konsep-konsep dalampembelajaran garis dan sudut serta siswa dapat menyelesaikan masalah-masalah yang berkaitan dengan materi garis dan sudut pada kehidupan sehari-hari.
The aims of this study to determine student learning outcomes in mathematical logic material after the application of logic pipe props. This research was conducted in class X.3 of SMA Muhammadiyah Pagaralam. The research method used was the experimental method with the category of one group pretest posttest design. Data collection techniques used in this study was documentation, observation, interviews, and tests. From the results of the study it can be seen that student learning outcomes in mathematical logic material using logical pipe props can be said good. This can be seen during the learning process through observation and the Student Worksheet that is done by students. In these learning activities, students in the group are active in completing the Student Worksheet and students look skilled in using the logic pipe props, so students can find out for themselves the concepts of conjunction, disjunction, implications and implications. In addition, student learning outcomes that can be seen from the post test results are classified as having a high average where the average post test score of students is 83.00. From the average score obtained by students and the activeness of students in the learning process, it can be concluded that the logical pipe props are well used in learning mathematical logic material.
This study aims to determine 1) the student's activity during the implementation of PBL models and 2) student learning outcomes after the implementation of PBL models through the creation of grass park on the material circle in class VIII SMP Negeri 1 Pagaralam. This research is an experimental research category one shot case study involving 32 students of class VIII SMP Negeri 1 Pagaralam. The results showed that the activity of students during the loading applied to the model PBL through grass park is categorized as very active seen from the activity of visual, verbal, listening, metrics, and writing. While student learning outcomes after the implementation of the PBL model through the creation of grass park are categorized very well as indicated by the average value of students. Thus, the PBL model is very suitable for use in mathematics, especially in the area of a circle of matter.
