Abstract

Penelitian ini merupakan penelitian kualitatif dengan tujuan untuk mengetahui kendala-kendala yang dihadapi oleh siswa baik itu ketika mengerjakan soal sendiri, maupun dikerjakan secara berkelompok. Teknik pengumpulan data yang digunakan dalam penelitian ini adalah teknik komunikasi langsung, dimana peneliti melakukan kontak langsung dengan responden melalui tatap muka. Instrumen yang digunakan dalam penelitian ini adalah tes dan wawancara. Siswa diberikan tes terkait dengan materi sistem persamaan linear dua variabel. Tes ini dimaksud untuk  mengetahui kemampuan siswa dalam memahami konsep matematika dan wawancara dilakukan untuk mengetahui kesulitan yang dihadapi oleh siswa. Setelah data diperoleh kemudian dianalisis menggunakan triangulasi data. Dari hasil penelitian ini diperoleh bahwa siswa yang berada pada kelompok dapat saling bertukar pikiran dalam memahami konsep matematika materi sistem persamaan linier dua variabel daripada siswa yang mengerjakan soal secara  mandiri. Dapat disimpulkan pembelajaran kelompok mempermudah siswa dalam memahami konsep karena adanya proses pertukaran pikiran saat memahami konsep dari suatu masalah.Kata Kunci: Konsep, Kelompok, Masalah

Abstract

This research begins with the results of interviews and observations which show that the value of students' mathematical critical thinking skills in class VII SMP Negeri 1 Sungai Lala is still low and there are differences between female students and male students in the process of solving the exercises given by the teacher. The purpose of this study was to determine whether there is a difference between critical thinking skills based on gender differences. This type of research is descriptive qualitative research. The subjects in this study were four students consisting of two female students and two male students, in which the four students were selected based on their critical thinking ability scores. The research instruments were questionnaire sheets and test questions. The data obtained will be analyzed by means of data reduction, data presentation, and data verification. Based on the results of the study showed that the results of the questionnaire percentage of critical thinking skills for female students were higher than for male students. The percentage results obtained were 50.77% for female students and 49.23% for male students. The completion of critical thinking ability test questions between female students and male students has differences. Female students have been able to master the five indicators of critical thinking skills in solving test questions, while for male students there are two indicators of critical thinking abilities that they have not yet mastered. In terms of conclusion, that female students have excellent critical thinking skills while male students have good critical thinking skills.

Abstract

Abstract This study aims to determine the difficulty of students in class VIII in understanding the understanding of mathematical concepts in the system of linear two-variable equations and the principles experienced by students in solving the problem stories for two-variable linear equation systems and the factors that cause students to experience these difficulties. The method used in this research is descriptive method. The subjects used in this study were students of class VIII selected with consideration. The instrument used is a written test in the form of essays and interview guidelines. From the data analysis, it is known the difficulties and the factors causing the difficulties experienced by students. difficulty in converting story problems into mathematical sentences, difficulty in operating with the substitution method, difficulty in operating addition and subtraction. The factors that cause difficulties are the lack of mastery of the system of linear equations for the two variables SPLDV, the lack of persistence, lack of accuracy when working on the questions, do not master the concept of the linear system for the two variables SPLDV.

Abstract

The background of the problem in this study is the lack of active student learning in the learning process. To see the activeness of student learning the teacher uses a learning model, namely the Hybrid Learning model. The Hybrid Learning model can be used to increase student learning activity and can eliminate student boredom in receiving material delivered by educators, especially in the current situation. Hybrid Learning models can be used in online learning processes so that students can carry out the learning process even if only at home or at school with limited time. This research is a descriptive qualitative research (descriptive research) in which the research method is to collect data in the form of words, pictures, not numbers and all that is collected is likely to be the key to what is being studied. The subjects of this study were selected based on students' daily scores on the previous material, namely lines and angles, in which the subjects of this study included 5 students, 3 of whom had the highest daily scores and 2 of them had the lowest daily scores. Data collection techniques are observation, Focus Group Discussion (FGD), documentation. Furthermore, the data obtained will be analyzed based on indicators of student learning activity. The data analysis technique in this study is by reducing data, presenting data, and verifying data. Based on the final results of the questionnaire score, namely 31% chose to strongly agree, 26% chose to agree, 27% chose to be undecided, 11% chose to disagree, and 5% chose to strongly disagree and the results of interviews using the Hybrid Learning model students became more active during the learning process. So it can be concluded that student learning activity is good.

Abstract

Penelitian ini dilatarbelakangi oleh rendahnya kemampuan pemecahan masalah matematis siswa kelas VII MTs Nurul Falah. Penelitian ini bertujuan untuk mengetahui efektivitas dengan menggunakan model pembelajaran Somatic Auditory Visualization Intellectually (SAVI) berbantuan aplikasi GeoGebra dengan pembelajaran konvensional terhadap kemampuan pemecahan masalah matematis siswa kelas VII MTs Nurul Falah. Jenis penelitian ini ialah Quasi eksperimen, dengan design The Randomized Posttest Only Control Design. Populasi pada penelitian ini adalah kelas VII. Sampel dipilih menggunakan teknik  simple random sampling berdasarkan uji normalitas, uji homogenitas, uji kesamaan rata-rata. Dari hasil tes awal dengan teknik Simple Random Sampling yang kemudian diperoleh kelas VII A sebagai kelas eksperimen dan kelas VII C sebagai kelas kontrol. Teknik pengumpulan data pada penelitian ini yaitu tes kemampuan pemecahan masalah matematis siswa. Teknik analisis dalam penelitian ini menggunakan Uji-t diperoleh thitung > ttabel (6,668 > 1,998) dan Sig. < 0,05, yaitu 0,00 < 0,05 dengan (df) n-2 maka keputusan yang diambil adalah H1 diterima H0 ditolak. Sehingga dapat disimpulkan bahwa “ Model pembelajaran Somatic Auditory Visualization Intellectually (SAVI) berbantuan aplikasi GeoGebra efektif terhadap kemampuan pemecahan masalah matematis siswa kelas VII MTs Nurul Falah”.
