The spread of the Covid-19 virus globally continues to grow. The impact felt by Indonesia in addition to the many positive cases, economic, social and educational system problems. The learning process that has been carried out face-to-face has become undisturbed, so that the learning process changes its function to online learning. The purpose of this research is to obtain information on how to describe the implementation process of learning for students of the Pamulang University Mathematics Study Program during the Covid-19 pandemic as an effort for Higher Education to stop and break the chain of spreading covid-19. The research subjects were students of the Mathematics Study Program. Data processing was carried out by interviewing through cloud meetings and questionnaire response sheets using the google format. Interviews and questionnaire sheets were conducted with questions that were compiled and developed with related literature. Miles & Huberman's interactive analysis techniques were used in this study. This study obtained the results, namely, (1) students already have basic learning facilities such as leptops, computers, android-based mobile phones and internet networks; (2) The learning process has not been maximally carried out yet; (3) Lack of supervision from both lecturers and parents during the lecture or learning process; (4) The online learning process has the advantage of flexibility in time, encourages and trains students to study independently.
Matematika termasuk salah satu mata pelajaran yang digeluti dari tingkat dasar, menengah hingga perguruan tinggi. Salah satu tuntutan dari pembelajaran matematika adalah kemampuan siswa dalam pemahaman relasional. Dengan dikuasainya kemampuan tersebut, siswa akan mendapatkan cara untuk bergerak dengan mudah dan terampil. Namun sesuai perkembangannya, kebanyakan siswa menghadapi kesulitan dalam menguasai konsep matematika, khususnya materi peluang. Oleh karena itu, peneliti tertarik melakukan penelitian untuk melihat kemampuan pemahaman relasional pada materi peluang. Salah satu upaya yang ditawarkan menggunakan pendekatan matematika realistik. One group pretest-posttest design menjadi pilihan metode penelitiannya. Populasinya adalah siswa kelas VIII MTsM Sulit Air semester II Tahun Ajaran 2020-2021. Sampelnya adalah siswa kelas VIII2 pada tahun pelajaran yang sama. Hasil dari penelitian ini didapatkan nilai N-Gain sebesar 0.57 dalam kategori efek sedang. Berdasarkan kategori tafsiran efektivitas adalah sebesar 56.81% dalam kriteria cukup efektif. Kesimpulannya adalah pembelajaran berorientasi matematika realistik efektif dalam membangun pemahaman relasional untuk materi peluang.
Often the use of repeated questions and answers is given by the teacher so that they cannot analyze students' mathematical literacy abilities. There needs to be a solution to the PISA problem so that student competencies can be seen clearly. The teacher should analyze this so that it does not happen continuously so that a way can be found to overcome it. The purpose of this study was to determine the mathematical literacy of junior high school students when working on PISA questions in the Minang context. This type of research is descriptive qualitative research. The results of the PISA test and interviews became the data in this study. To find out more detailed data, the authors took the research subjects based on the results of the PISA test later and categorized the subjects into the highest, medium and lowest. In this study, researchers used indicators of mathematical literacy level according to PISA. The results of this study indicate that in formulating the situation mathematically is 75%, reasoning 33.05% and solving problems 14.44%. That is, on average, students are only able to answer problems only up to level 2 PISA, that the ability to formulate situations mathematically.
The research problem in is the students’ mathematical reasoning ability is low, it is caused by learning device designed by the teacher does not yet support how to construct student’s mathematical reasoning ability. Through the development of this learning instrument, it is expected that students’ abilities in mathematical reasoning can increase. Learning tools are developed in the form of Lesson Plan and Student’s Worksheets. We use research Plomp’s model: initial research, prototype phase, and assessment phase. The results of preliminary analysis research, mathematical reasoning ability and student learning outcomes are still low. Teachers and students need learning tools based on Learning Cycle 5E with simple language and guide students to understand mathematics well. This study produced a valid mathematics learning device.
The Treffinger model is a series of learning processes designed to solve mathematical problems by students creatively through 3 (three) stages. The first stage is the Basic tool, the second stage is Practice with Process, and the third stage is Working with real Problems. The purpose of this study was to determine how much influence the Treffinger model has in improving students 'creative thinking skills in learning Calculus 1. The formulation of the problem in this study is whether the Treffinger model can improve students' creative thinking skills in learning Calculus 1 ?. Is the creative thinking ability of students in the aspects of analyzing (C4), evaluating (C5) and creating (C6) who learn using the Treffinger model higher than students who learn with the conventional model in the calculus 1 course? The method used in this research is quasi-experimental research. The design used in this study is a design with unequal groups. The conclusion in this study, in general, is that the application of the Treffinger model is effectively used in order to improve students' creative thinking skills in calculus 1 subject. ) and create (C6) who learn using the Treffinger model higher than the ability of students who learn using conventional models.
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.
