Abstract

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.

Abstract

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 pre-cycle 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.

Abstract

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. Key words: Mathematical reasoning, matrix.
