Abstract

This research is a Classroom Action Research. In this research, learning tools are arranged: Lesson Plans, Teacher's Guidebooks and Student Worksheets. Next, arrange essay test instruments and student observation sheets, before the test instruments are used, they are tested first and the results are used for research instruments. This research was carried out through 2 cycles before being given action, first given a diagnostic test with a minimum category of enough to get 40.91%. Furthermore, given a test of mathematics learning outcomes in the first cycle, it was 77.27 which increased to 86.36 in the second cycle. The percentage of active student activity increased, this was obtained from the average level of student activity in the first cycle of 76% then in the second cycle it rose to 85.28. The teacher's ability to manage learning cycle I and cycle II is included in the "Good" category. Based on these results, this study suggests the application of the Think Pair Share learning model to improve students' mathematics learning outcomes in class VII-3 of SMP Negeri 2 Batahan.

Abstract

The type of research used is Classroom Action Research (CAR) using two learning cycles, with the subject of class X-1 SMA Negeri 1 Batangtoru totaling 25 people. While the object of this research is the use of problem-based learning model with Blended to improve students' mathematical problem solving ability. Before the instrument was used, a test trial was conducted to see the validity and reliability of the test. Of the 6 test questions in the first cycle and 6 test questions in the second cycle, 5 test questions in the first cycle were valid (valid) and 5 test questions in the second cycle were valid (valid), and all test questions were reliable with a test reliability coefficient of 0.926 with a level high reliability and has a validation correlation with the moderate category. The average result of the students' mathematical problem solving ability test on the students' mathematical problem solving ability test in the first cycle was 68.80 in the "Enough" category with 64.00% completeness and the percentage of student activity levels was 70.31%. Then continue the activities of the second cycle where the average result of the students' mathematical problem solving ability test in the second cycle is 83.04 in the "Good" category with 92.00% completeness percentage and 89.06% student activity level percentage

Abstract

One thing that must be considered in learning mathematics is the model or method used in the learning process, because the method has an important role in determining student success. This study aimed to determine whether there is an effect of student motivation and interest in learning on learning outcomes on the subject of linear equations of one variable. The population in this study were students of class VIII Ponpes Al-Yusufiyah, with the number of class VIII as many as 7 classes. In this study, the sample was taken from the population using the Cluster Random Sampling technique, namely the research took the sample based on a predetermined population area. The number of samples is 20 students. The data collection method used in this study is a questionnaire and documentation method. For the final data analysis using Simple Linear Regression. The constant (a) is 36.714, meaning that if the Guided Effect level variable is 0, then the volume variable for learning outcomes is 36,714. The regression coefficient of the Guided Inquiry variable has a positive value of 13.671 indicating that if the learning outcomes increase by 1 (unit), then the way the learning outcomes increase by 13.671 coefficients is positive, meaning that there is a positive relationship between Guided Inquiry and Learning Outcomes.

Abstract

Abstrak Penelitian ini bertujuan untuk meningkatakan kemampuan penalaran matematis siswa melalui pendekatan open ended. Jenis Penelitian ini adalah penelitian tindakan kelas (PTK) yang terdiri dari dua siklus yaitu siklus I dan siklus II. Subyek penelitian ini adalah kelas VIII-A SMP Negeri 2 Muara Sipongi yang berjumlah 26 orang. Objek yang diamati dalam penelitian ini adalah seluruh proses dan hasil pembelajaran matematika untuk meningkatkan kemampuan penalaran matematis siswa melalui penerapan pendekatan open ended. Perangkat pembelajaran yang digunakan dalam penelitian ini adalah rencana pelaksanaan pembelajaran (RPP), buku panduan guru (BPG), lembar kerja siswa (LKS), instrument tes, lembar observasi kemampuan guru dalam mengelola pembelajaran dan lembar observasi aktivitas siswa. Instrumen tes yang digunakan dalam penelitian ini adalah berbentuk Essay yang sudah dihitung melalui perhitungan validutas, reliabilitas, dan tingkat kesukaran serta daya pembeda. Hasil penelitian menunjukkan bahwa kemampuan penalaran matematis siswa dengan penerapan pendekatan Open Ended pada siklus I diperoleh 53,84% atau 14 orang dari 26 siswa termasuk dalam kategori “tuntas”. Pada siklus II persentase ketuntasan hasil teskemampuan penalaran matematis siswa kelas VIII-A SMP Negeri 2 Muara Sipongi sebesar 96,15 atau 25 orang dari 26 siswa termasuk dalam kategori “tuntas”. Berdasarkan dari hasilpengamatan observer proses keterlaksanaan pembelajaran melalui pendekatan open ended siswa kelas VIII A SMP Negeri 2 Muara Sipongi dari pertemuan pertama samapai perteuan terakhir berjalan denagan baik. Kata Kunci: Pendekatan Open Ended, Penalaran Matematis
