Abstract

Solving a problem in geometric transformation that is prioritized is the ability to think visually, this is because visualization is the heart of mathematics to solve a problem, besides that visualization can also make it easier to understand abstract mathematics, and can be used as a strategy for solving mathematical problems to be very simple. This study aims to describe the visual thinking ability of mathematics education students on the material of geometric transformation. The type of research used in this research is descriptive qualitative research. The subjects in this study were 5 students. Written tests related to geometric transformation questions, such as questions, reflections, translations, and dilations were used as data sources in this research. By describing each instrument that has been done by students in accordance with the indicators of visual thinking ability, data analysis techniques are used. The results of this study indicate that students' thinking skills only reach the stage of sorting, searching, and finding. It means only to the acquisition and reasoning. This can be seen from the responses of several students, namely students (1) four stages and three principles of visual thinking ability are achieved. Students can sort out the questions given and look for information to get answers, and can describe and visualize the answers that have been obtained. Student response (2) only did not reach the step of describing and the principle of individuation. This means that students cannot explain and describe answers in the form of pictures or graphs correctly. Student responses (3) only reached the stage of sorting and obtaining or in other words only understanding what was asked. Students in response (4) only did not reach the step of describing and the principle of visualizing/illustrating. So that it can be used as a reference related to visual research, especially on geometry material.

Abstract

Abstrak Kemampuan visualisasi merupakan aspek krusial dalam memahami materi dimensi tiga. Tujuan penelitian ini yaitu menggambarkan kemampuan visualisasi siswa sekolah menengah atas dalam pembelajaran materi dimensi tiga berdasarkan gaya belajar. Subjek penelitian kualitatif ini dipilih dengan metode purposive sampling. Teknik pengumpulan data menggunakan tes essay berdasarkan indikator ketrampilan visualisasi. Teknik analisis data meliputi pengumpulan data, kategorisasi data, penyajian data dan penarikan kesimpulan. Hasil penelitian menunjukkan kemampuan visualisasi siswa berbeda berdasarkan gaya belajar. Siswa dengan gaya belajar visual menunjukkan kemampuan visualisasi yang sangat baik yaitu menyelesaian masalah, pencarian pola, pengonsepan, pengimajinasian, dan memvisualkan. Siswa dengan gaya belajar auditori menyelesaikan masalah, pencarian pola, dan memvisualkan, namun belum optimal dalam pengimajinasian dan pengonsepan. Siswa dengan gaya belajar kinestetik menyelesaian masalah dan pencarian pola, sedangkan mengimajinasikan hanya tercapai sebagian, dan pengonsepan serta memvisualkan belum terpenuhi secara memadai. Temuan ini menunjukkan adanya hubungan erat antara gaya belajar dan pencapaian kemampuan visualisasi dalam memahami materi dimensi tiga. Abstract Visualization ability is a crucial aspect in understanding three-dimensional material. The purpose of this study is to describe the visualization ability of high school students in learning three-dimensional material based on learning styles. The subjects of this qualitative study were selected using the purposive sampling method. The data collection technique used an essay test based on visualization skill indicators. Data analysis techniques include data collection, data categorization, data presentation and drawing conclusions. The results of the study showed that students' visualization abilities differed based on learning styles. Students with a visual learning style showed very good visualization abilities, namely solving problems, finding patterns, conceptualizing, imagining, and visualizing. Students with an auditory learning style solved problems, finding patterns, and visualizing, but were not optimal in imagining and conceptualizing. Students with a kinesthetic learning style solved problems and searching for patterns, while imagining was only partially achieved, and conceptualizing and visualizing had not been adequately fulfilled. These findings indicate a close relationship between learning styles and the achievement of visualization abilities in understanding three-dimensional material.

Abstract

Interviews with mathematics teachers and a number of 11th grade students at SMA Pelita Ngabang showed that low student independence in learning had a direct effect on their mathematics learning outcomes. It was not uncommon for some 11th grade students to experience difficulties in solving composition function problems. This was due to a lack of independent learning strategies, a lack of student motivation to learn, and a lack of discipline in managing study time. In addition, students' dependence on explanations provided by teachers also contributes to suboptimal learning outcomes. This study aims to analyze the influence of independent learning on the mathematics learning outcomes of 11th grade students on the topic of composite functions at SMA Pelita Ngabang. The research approach applied uses a quantitative method with a correlational research design. Sampling was conducted using purposive sampling, while data collection was carried out through the distribution of questionnaires and exam questions. Data processing techniques in this study included validity testing, reliability testing, descriptive statistical analysis, normality testing, linearity testing, homogeneity testing, and simple linear regression testing. The results of statistical analysis using SPSS version 25 software show that the hypothesis test with the F test produced a significance value of 0.003, which is less than 0.05. In addition, the R Square coefficient of determination showed a value of 0.331, indicating that independent learning has a significant effect on mathematics learning outcomes of 33.1%, which is classified as moderate.
