    Kemampuan berpikir kritis seseorang dalam suatu bidang studi tidak dapat terlepas dari pemahamannya terhadap materi bidang studi tersebut. Dengan demikian agar siswa dapat berpikir kritis dalam matematika, maka siswa harus memahami matematika dengan baik. Tujuan penelitian ini adalah meningkatkan aktivitas dan kemampuan berpikir kritis siswa pada pembelajaran matematika dengan model Cognitive Growth berbasis Scientific Approach. Penelitian ini merupakan Penelitian Tindakan Kelas (PTK) yang dilaksanakan di SMP IT Ihsanul Fikri Kota Magelang pada kelas VIIIB mata pelajaran Matematika. Instrumen yang digunakan yaitu lembar pengamatan aktivitas siswa, lembar tes kemampuan berpikir kritis, dan lembar observasi pelaksanaan pembelajaran. Presentase peningkatan berpikir kritis siswa pada siklus I = 57,58 %, siklus II = 67,24%, dan siklus III = 89,01%. Presentase untuk aspek aktivitas siswa pada siklus I=39,20 %, siklus II = 59,40%, dan siklus III = 93,93%. Dapat disimpulkan bahwa penerapan pembelajaran dengan model Cognitive Growth berbasis Scientific Approach dapat meningkatkan aktivitas dan kemampuan berpikir kritis siswa kelas VIII pada materi pokok kubus dan balok di SMP IT Ihsanul Fikri Kota Magelang

    The problem solving ability is needed for the students to be able to face the challenges of education on cognitive aspects. Meanwhile, in the affective aspect, the students’ activities also play an important role in the process of learning mathematics in higher education. Armed with activities and mathematical problem solving ability, they are expected to be more adaptive in their efforts to find solutions for each problem. The purpose of this research is to improve the activities and ability to solve mathematics problems in the second semester students in the Integral Calculus course using the Cognitive Growth model. This is a Classroom Action Research (CAR in the even semester 2018/2019). The subjects of this research are the second semester students of the Mathematics Education Study Program at a higher education institution in Magelang, Central Java, Indonesia. The data collection techniques in this research are the test, observation, and interview. The percentage for the aspect of the students’ activities in the first cycle = 51.51%, the second cycle = 58.56%, and the third cycle = 65.48%. The percentage of improvement in the students' mathematical problem solving ability in cycle I = 45.08%, cycle II = 40.08%, and cycle III = 56.59%. Therefore, it can be concluded that the application of the Cognitive Growth model can improve the activities and problem solving ability in the second semester students in the Integral Calculus course

    Inclusive schools are organized by the government in order to provide opportunities to all students regardless of conditions and backgrounds.  Deaf as individuals who have barriers and special needs are still discriminated against so that they cannot study in inclusive schools due to lack of facilities and knowledge of the learning process of deaf students, especially mathematics subjects. The purpose of this study was to analyze the implementation and obstacles to the mathematics learning process of deaf students in inclusive schools. The method used is a qualitative descriptive research method. The results of the research obtained include: 1) at the learning planning stage mathematics teachers maked unit planners while shadow teacher  maked IEP; 2) at the stage of learning implementation the learning system given to deaf students is the same as other regular students, mathematics teachers used clear lip gestures in explaining, and deaf students was accompanied by shadow teacher during the learning process; 3) at the evaluation stage, the evaluation questions given to deaf students was the same as other regular students; 4) GPK is constrained  in how to explain the material to deaf students, set strategies in providing motivation and providing consequences when deaf students are lazy, and teachers must be ready to re-explain the material that has been delivered.

    This study aims to analyze the influence of differences in learning models on problem-solving ability, the influence of differences in student learning styles on problem-solving ability, and the interaction between learning models and student learning styles on problem-solving ability. The design of this study is a pseudo-experimental design. The samples in this study were students of class VII A and class VII C of SMP Negeri 3 Muntilan who were selected by cluster random sampling. Based on the results of the hypothesis test conducted with the two-way ANAVA test, the results were obtained that 1) there were differences in the influence of learning models on problem-solving ability; 2) there is no difference in the influence of the four learning styles on problem-solving ability; 3) there is no interaction between the learning model and the student’s learning style on problem-solving ability. The conclusions of this study are 1) students with ethnomathematics-based PBL models have better problem-solving abilities than students with direct learning models; 2) students with convergent, divergent, assimilated, and accommodation learning styles with an ethnomathematics-based PBL models have better problem-solving abilities than students with direct learning models.Penelitian ini bertujuan untuk menganalisis pengaruh perbedaan model pembelajaran terhadap kemampuan pemecahan masalah, pengaruh perbedaan gaya belajar siswa terhadap kemampuan pemecahan masalah, dan interaksi antara model pembelajaran dan gaya belajar siswa terhadap kemampuan pemecahan masalah. Desain penelitian ini yaitu desain eksperimen semu. Sampel dalam penelitian ini adalah siswa kelas VII A dan kelas VII C SMP Negeri 3 Muntilan yang dipilih secara cluster random sampling. Berdasarkan hasil uji hipotesis yang dilakukan dengan uji ANAVA dua jalan diperoleh hasil bahwa 1) terdapat perbedaan pengaruh model pembelajaran terhadap kemampuan pemecahan masalah; 2) tidak terdapat perbedaan pengaruh keempat gaya belajar terhadap kemampuan pemecahan masalah; 3) tidak terdapat interaksi antara model pembelajaran dengan gaya belajar siswa terhadap kemampuan pemecahan masalah. Kesimpulan dari penelitian ini adalah 1) siswa dengan model PBL berbasis etnomatematika memiliki kemampuan pemecahan masalah lebih baik daripada siswa dengan model pembelajaran langsung; 2) siswa dengan gaya belajar konvergen, divergen, asimilasi, dan akomodasi memiliki kemampuan pemecahan masalah yang sama baiknya; 3) siswa dengan gaya belajar konvergen, divergen, asimilasi, dan akomodasi dengan model PBL berbasis etnomatematika memiliki kemampuan pemecahan masalah lebih baik daripada siswa dengan model pembelajaran langsung

    The mathematics literacy abilities are strongly needed for the students to be able to face educational challenges from the cognitive aspects. The students' mathematics literacy abilities can be viewed from various dimensions, one of whixzch is the learning styles. The purpose of this research is to analyze the students' mathematics literacy abilities in inferential statistics subject based on the learning styles. This is a qualitative descriptive research. The subjects of this research are the fourth semester students at a higher education institution in Magelang, Central Java, Indonesia, who are currently taking inferential statistics course. The instruments used in this research are test and interview instruments. The data analysis is carried out through data reduction, data presentation, and drawing conclusions. The students’ mathematics literacy abilities with divergent learning styles are only able to arrive at the formulating step. The students’ mathematics literacy abilities with convergent learning styles are able to take the mathematical literacy processes. The students' mathematics literacy abilities in the assimilation learning style have come to the interpreting step, but they have not been able yet to solve the problems well. The students' mathematics literacy abilities in the accommodation learning style have been able to understand and check (formulating and interpreting) well but in preparing plans or arguing (employing stage) in solving the problems, it has not been achieved yet properly. Based on the research results, it is found that each different learning style has its own different mathematics literacy abilitiesKemampuan literasi matematika sangat diperlukan agar mahasiswa mampu menghadapi tantangan pendidikan pada aspek kognitif.Kemampuan literasi matematika mahasiswa dapat ditinjau dari berbagai dimensi, salah satunya gaya belajar.
