The objective of this study is to determine students' responses to learning in the network (online) in mathematics. This research uses a descriptive method with a qualitative approach. Data collection technique is questionnaire. The questionnaire consisted of positive and negative statements totaling 20 statements. The questionnaire is distributed via Googleform. Data analysis techniques are data reduction, data presentation and conclusion. The subjects are 29 students of Class XI MIPA 1 of SMA Negeri 1 Weru in the academic year 2019/2020. The result shows that the average percentage of student responses in mathematics received positive criteria. With the average percentage of students' responses to the first indicator, namely interest of 83.62% so it is included in the positive criteria. In the second indicator, motivation is 74.14% so it is included in the positive criteria. The third indicator is satisfaction at 80.17% so it is included in the positive criteria. In the fourth indicator, interest is 73.49% so it is included in the positive criteria. And the fifth indicator is the response of 75.43% so it is included in the positive criteria.

Subjek dalam penelitian ini adalah siswa kelas X MIPA 3 SMA Negeri 1 Bulu Sukoharjo sebanyak 28 siswa. Penelitian ini menggunakan Penelitian Tindakan Kelas (PTK). Penelitian Tindakan kelas ini meliputi dua siklus. Tiap-tiap siklus terdiri atas perencanaan, tindakan, pengamatan dan refleksi. Teknik pengumpulan data yang digunakan adalah menggunakan teknik tes dan non tes. Hasil penelitian dapat disimpulkan bahwa model pembelajaran kooperatif tipe Make A Match dapat membantu mengatasi masalah siswa kelas X MIPA 3 SMA Negeri 1 Bulu Sukoharjo Tahun Ajaran 2018/2019 bisa mencapai tingkat keberhasilan persentase aktivitas belajar siklus I sebesar 43% kemudian meningkat lagi pada siklus II menjadi 89%. Nilai rata-rata kelas dari pra siklus 55,60 dengan 5 siswa tuntas, naik menjadi 13 siswa dengan rata-rata 67,67 di siklus I, kemudian meningkat pada siklus II menjadi 24 siswa dengan rata-rata 75,35. Sedangkan untuk persentase hasil belajar siswa dari pra siklus 17,86% meningkat pada siklus I menjadi 46,43% selanjutnya meningkat lagi pada siklus II menjadi 86%.

The objectives of this study are to increase the activeness and students learning achievement through the Snowball Throwing type cooperative learning model with Discovery Learning. This research is a Classroom Action Research (CAR) which consists of 4 stages with 3 cycles. The subjects are 29 students of class VII B SMP Negeri 16 Surakarta for academic year 2019/2020. The data collection techniques in this study are test, observation, and documentation techniques. The data analysis technique is carried out by analyzing the observation sheet and the analysis of the success of the action. Based on the research, the percentage of pre-cycle activeness data is 33.38%, the first cycle is 42.90%, the second cycle is 52.40% and the third cycle is 71.50%, while for classical completeness precycle learning achievement is obtained 20.69% , cycle I 27.58%, in cycle II it increased to 44.83% and cycle III increased to 75.86%. From the results obtained, it can be concluded that the application of the Snowball Throwing type cooperative learning model with Discovery Learning can increase the activeness and students learning achievement of class VII B students of SMP Negeri 16 Surakarta in the academic year 2019/2020.

The purpose of this study was to determine how the students' mathematical reasoning abilities towards the matrix material. The data in this study were obtained from the results of filling out questionnaires and also interviews. Sources of data in this study were the subjects from which the data were obtained, namely students of class XI-MIPA 3 SMA N 1 Tawangsari. The data analysis technique used was data reduction, data presentation and conclusion drawing. The results of the data analysis from the questionnaire showed that the average percentage of student responses to mathematical reasoning abilities on the matrix material was 60.75% and was in the medium category. With the percentage on each indicator, namely on indicator 1 (students do calculations with the applicable mathematical formula / rules) of 55.63% so that it is included in the moderate category, students with the moderate category have aspects of the ability to understand question commands and are only weak at calculation operations. In indicator 2 (students draw general conclusions based on mathematical processes / concepts) the percentage is 61.25% so it is included in the medium category. In indicator 3 (students make estimates) the percentage is 81.25% so that it is included in the high category, students with high categories have aspects of the ability to understand question commands, question logic and can complete counting operations. While the percentage on indicator 4 (students draw conclusions based on the similarity of mathematical processes / concepts that are seen) is 54.5% so it is included in the low category, students with low categories have aspects of the question's melogical ability and are only weak in counting operations. The average percentage of the four indicators is 63.16% so that student responses can be said to be in the medium category. In this study, checking the validity of the data used triangulation techniques, namely by comparing the results of the study with the results of interviews. From the comparison of data analysis with questionnaires and interviews, it can be concluded that students with mathematical reasoning on the matrix material are in the medium category.
