The method used in this research is quasi experiment. Sampling technique using cluster random sampling and the samples were taken from grade 8 in one of junior high school in Bandung. The sample was 45 students, consisting of the experimental class (n = 24 students) and the control class (n=21 students). The experimental class is taught by inquiry-based laboratory activities, while the control class is taught by non-inquiry laboratory activities. The result of this research shows that the experimental class got N-Gain of 0.60, while the control class got N-Gain of 0.44, and both classes proven to have statistically significant different improvement.

Abstrak Penelitian ini bertujuan untuk mengetahui pemecahan masalah dari masing-masing gaya belajar yang berbeda. Penelitian ini termasuk dalam penelitian deskriptif-kualitatif. Popuasi yang diambil dalam penelitian ini adalah siswa SMPN 1 Kibin tahun ajaran 2019/2020. Teknik pengambilan sampel penelitian menggunakan teknik cluster random sampling. Instrumen yang digunakan dalam penelitian ini berupa kuesioner, tes, wawancara, dan peneliti. Data mengenai menganalisis pemecahan masalah diambil dari kuesioner dan tes. Hasilnya didapat gaya belajar visual mendominasi. Kemudian 1 siswa dari gaya belajar yang berbeda dijadikan sampel untuk di wawancara. Hasil analisis menunjukkan pemecahan masalah setiap siswa berbeda karena dipengaruhi oleh gaya belajar. Gaya belajar visual dalam pemecahan masalah cenderung menekankan pada soal tes dan mencari informasi yang mendetail untuk memecahkan masalah. Gaya belajar auditorial dalam memecahkan masalah cenderung mengandalkan ingatan ketika pembelajaran. Gaya belajar kinestetik dalam pemecahan masalah cenderung memahaminya terlebih dahulu, kemudian dikonstruksikan dalam kehidupan sehari-hari. Dari hasil tersebut dapat disimpulkan bahwa gaya belajar memegang peranan penting dalam pemecahan masalah. Kata kunci : Pemecahan masalah; Gaya belajar visual; Gaya belajar auditorial; Gaya belajar kinestetik   Abstract This study aims to determine the problem solving of each different learning style. This research is included in descriptive-qualitative research. Populations taken in this study were students of SMPN 1 Kibin 2019/2020 school year. The research sampling technique used cluster random sampling technique. The instruments used in this study were in the form of questionnaires, tests, interviews, and researchers. Data regarding analyzing problem solving is taken from questionnaires and tests. The result is that the visual learning style is dominated. Then 1 student from a different learning style is sampled to be interviewed. The analysis shows that each student's problem solving is different because it is influenced by learning styles. Visual learning styles in problem solving tend to emphasize test questions and look for detailed information to solve problems. Auditory learning styles in solving problems tend to rely on memories when learning. Kinesthetic learning styles in problem solving tend to understand them first, then constructed in daily life. From these results it can be concluded that the learning style plays an important role in problem solving. Keywords: Problem solving; Visual learning style; Auditory learning style; Kinesthetic learning style

This research is aimed to describe a technology-integrated collaborative learning, exploring the student perception associated with the implemented learning method as well as observing the effectiveness of this method compared to the individual method. This research was conducted in Islamic Institute of Ma’arif NU Metro – Indonesia in 2017/2018 academic year. Through the application of cluster random sampling technique, about 28 students were determined as the research sample. The research sample was the fifth semester students of mathematics education who are currently learning the geometric transformation subject. The experimental class which becomes the focus of researcher is consist of 28 students who were derived from the cluster random sampling technique. This research design is a mixed research. Observation sheet, interview, and test of problem solving capability were used as the data collecting instrument. The results of this research indicates that the collaborative process is performing well. The learning process was conducted in the class, not in the computer laboratory. The limited number of laptop did not impact the learning process. The observation results indicate that the level of student enthusiasm in following the learning process is adequately high. The positive comments from students show that the technology-integrated collaborative method has supported them to comprehend the mathematics concepts as well as growing the high intention of learning. Negative comments that occur are associated with the complexity of studied material and the difficulty in using the application for a small number of students. The test results of problem solving capability has shown that the method of technology-integrated collaborative learning provides better results compared to the individual learning..
