Penelitian ini bertujuan untuk mendeskripsikan proses pengembangan komik sebagai media pembelajaran matematikadan mendeskripsikan respon dan hasil belajar siswa setelah menggunakan komik sebagai media pembelajaran matematika pada materi perbandingan kelas VII SMP. Jenis penelitian yang digunakan adalah Reserach and Develop (R&D) dengan tahap penelitian 3-D, yaitu tahap pengembangan (define), tahap perancangan (design) dan tahap pengembangan (develop). Data dikumpulkan dengan instrument penelitian berupa angket terdiri atas lembar validasi dan angket respon siswa serta lembar tes yang selanjutnya dianalisis secara deskriptif. Validasi terdiri dari validasi materi yang menghasilkan nilai rata-rata total 3,625 dengan kategori sangat valid dan validasi media yang menghasilkan nilai rata-rata total 3,47 dengan kategori valid. Angket respon siswa dan lembar tes diberikan kepada subjek setelah uji coba menggunakan komik sebagai media pembelajaran matematika. Hasil yang diperoleh adalah sangat positif dengan persentase 92% untuk respon siswa dan seluruh siswa tuntas dalam tes hasil belajar dengan KKM 75.
This study aimed to describe the level of students' reasoning ability to solve the problems on flat sides of Geometry with the level of mathematical reasoning ability of high, moderate and low. The types and the research approaches used were descriptive qualitative and quantitative research design. The research subjectswere 6 students from class VIIIF. The form of data collection included 4 items ofwritten questions test and interview on the subject selected. Based on the analysis, the average value of the entire instrument about the mathematical reasoning abilities gained 71.5% for the indicators that carried out the calculations based on mathematical formulas or rules applicable. While 73.33% and 71.5% for the indicator of conclusions and 66.67% for the indicator ofestimation, that ifsummedup and averaged the percentage was 69%. The ability of class VIIIF students’ mathematical reasoning was fair.
This study aimed to describe the ability of mathematical literacy’s male and female students in Grade VIII. Based on the results of the interview, teacher accustomed to adopt problems of the textbook and national exams. Mathematical literacy was important to resolve the real problem in the form of the story matter. The research method used descriptive research. Data obtained from the mathematical literacy ability tests and interviews. The data was analyzed by observing the stages of how students in solving a problem were given. The results of the study were male students mathematical literacy ability was good enough in the settlement of the question of tests and reasonable when interviewed. Female students already have pretty good abilities in tests but were still lacking in reasoning and confident at interview sessions. Both of the students were men and women overall have been able to meet the competencies of mathematical literacy
The development of the flex media model looks like the beginning of the problems in the classroom, especially in the new normal. Students experience difficulties when given math problems. Students are less able to solve these problems, especially in understanding justifying mathematical ideas and arithmetic skills, and are less interested and enthusiastic when learning. This study aimed to develop a Moodle-based flex model learning media to improve students' mathematical hard skills with three-dimensional material. The study was used to research and develop the four-D model. The instruments used included validation, questionnaires, pre, and post-test questions, small-scale trials of 10 students, and large-scale trials with a purposive sampling technique of 30 class XII students. Data collection techniques include (1) validation questionnaires of media and material experts, (2) practicality questionnaires (student responses), and (3) pre-posttest questions. Material and media expert validator test with very decent results. The results of the student response questionnaire were reasonably practical regarding statements related to the practicality of the Moodle-based flex model media. The N-gain average score indicated a "moderate" improvement category. Based on the study results, the developed media meets valid, practical, and effective criteria for improving students' hard skills
Based on the evaluation result on the course of linear algebra, the result of mathematics student’s learning outcome, faculty of teacher training and education, University of Muhammadiyah Surabaya, from 26 students indicate that 30,76 % of students complete learning and 69,24% did not complete the target with average value 55,60. Based on the student's opinion, the course of linear algebra was difficult because has a high difficulty level, the learning system uses direct learning, and it causes the boredom. Furthermore, the reference material does not support completely for linear algebra. Thus we need additional learning models, so the students do not get bored and difficult by direct learning model that we used. In this case, we use “The Cooperative Learning Type TPS” model with 4 Me module in order to help the student to be able to work and shared with their friend to find problem solutions so that the interaction among learners occurs and the learning process becomes more active. We use the classroom action research method in this research. Based on the result of the research, we can improve 30% student’s learning result, 21 % of student’s activity and 95 % positive student’s response.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
