Abstract

SAVI kepanjangan dari Somatis, Auditori, Visual, dan Intelektual merupakan sebuah pendekatan dalam pembelajaran yang diharapkan mampu memberikan kontribusi yang baik dalam upaya untuk meningkatkan kemampuan komunikasi dan penalaran matematik serta kemandirian belajar siswa SMP. Dalam pendekatan SAVI seluruh indera dipergunakan dalam belajar. Kemampuan mendengar, membaca, menyimak, merefleksi diri, mengatakan sesuatu, melakukan tindakan, dan mempergunakan intelektual merupakan bagian penting dari pendekatan SAVI. Dengan kemampuan tersebut, akan memudahkan siswa dalam mengkomunikasikan matematika, menggunakan daya nalarnya sehingga mudah difahami dan akhirnya akan menumbuhkan rasa kemandirin belajar yang tinggi.Kata Kunci : Pendekatan SAVI, Komunikasi Matematis, Penalaran Matematis, Kemandirian Belajar SAVI stands for Somatic, Auditory, Visual, and Intellectual is an approach to learning that is expected to give a good contribution in an effort to improve communication skills and mathematical reasoning, the independence of junior high students. In all senses SAVI approach used in the study. Listening skills, reading, listening, reflection, say something, take action, and use the intellectual is an important part of the SAVI approach. With these capabilities, will allow students to communicate mathematics, using the power of reason that is easily understood and will ultimately foster a high sense of independent learning.Key words : SAVI Approach, Mathematical Communication, Mathematical Reasoning, Learning Independence

Abstract

This study aims to determine the effect of mathematics anxiety and learning motivation on students' mathematical connection abilities. This research was conducted in SMP Negeri 1 Cikampek class VII 9. In the selection of research samples using the cluster random sampling technique. With the method of Correlational research type of regression, the data used are quantitative data obtained from the inquiry questionnaire and learning motivation and mathematical connection ability test questions. Data processing techniques used in this study are using multiple linear regression. In this study quantitative data processing was performed using IBM SPSS 21.0 software for windows. The results of this study obtained a regression equation (Y=-58,623+0,678X1+0,359X2) which is linear with a determination coefficient of 30.3%, meaning that about 69.7% is explained outside of the regression equation. Thus, it was found that mathematics anxiety and learning motivation significantly influence students' mathematical connection abilities.

Abstract

Learning mathematics by understanding mathematical concepts is very important, with students understanding mathematical concepts will help problems in mathematics, even problems in everyday life. This study aims to determine the ability to understand students' mathematical concepts in algebraic form material. This research uses qualitative research with descriptive method. The subjects in this study were seventh grade students in one of the junior high schools in Purwakarta Regency and the selection of subjects was done by purposive sampling technique. The data collection technique used is a description test of understanding mathematical concepts in algebraic form with 3 questions. The data were analyzed by giving a score for each subject's answer, then the recorded score was changed in the form of a percentage value. The test results were analyzed according to the indicators of the ability to understand concepts. It can be seen from the results of the research that the indicator restating a concept has a percentage of 64% with a good level of understanding, indicators using and choosing certain procedures or operations have a percentage of 53% with a sufficient level of understanding, and indicators of applying concepts or algorithms in problem solving have a percentage of 53% with a sufficient level of understanding. All students' ability to understand mathematical concepts has a percentage of 57% with a sufficient level of understanding.

Abstract

This study aims to determine how the students’ difficulties in solving the test questions with indicators of the logical-mathematical thinking ability in one of the geometry materials, especially cubes. This study was conducted according to the facts in 9th-grade of SMP Negeri (State Junior High School)in one of the schools in Karawang Regency. This study used descriptive research with a qualitative approach.  The data were collected by an essay test consisting of 4 questions, and interviews. The subjects of the study were 28 9th-grade students of SMPN 1 Cikampek Karawang Regency. The instrument of the study used the essay test with indicators of logical-mathematical thinking ability according to (Andini, 2017): (1) The ability to conclude based on the appropriate portion; (2) The ability to conclude based on the examples; 3) The ability to conclude based on the existing data; (4) The ability to conclude based on the relationship between two variables. The data analysis techniques used were data collection, data reduction, data presenting, and concluding. The results of the study in the geometry materials show that all indicators of logical-mathematical thinking ability have not been achieved maximally. Only students with high category who meet the indicator, while the students who have moderate and low categories cannot meet the indicators. Out of 28 students, 3 students are in the high category with a percentage of 10.71%, 75% of students are in the moderate category, and 4 students are in the low category with a percentage of 14.29%. These results of the study show that students still have difficulty understanding and mastering the concepts to solve the test questions with the indicators of logical-mathematical thinking ability.
