Abstract

Abstract. The aim of this study described the feasibility of a project-based mathematics learning  geometri flat side material in one of Batu City Middle Schools. The research will be carried out using descriptive qualitative research. Subjects in this study were educators and students of class VII-B in one of the junior high schools in Batu City. These students are chosen because they tend to get bored easily and are less interested in learning mathematics. Data collection techniques used in this study consisted of three, namely: observation, test data and documents. The research instruments used were observation sheets of project-based mathematics learning implementation, and student learning outcomes test sheets. Overall the implementation of project-based mathematics learning methods has been implemented according to planning. Educator activities related to project-based learning have an average of 78% which is included in the well-implemented category. Therefore the implementation of project-based learning can be said to be feasible and needs to be developed again. Key words: geometri flat side, implementation, project based learning Abstrak. Tujuan dari penelitian ini yaitu mendeskripsikan keterlaksanaan perangkat pembelajaran matematika berbasis proyek pada materi bangun ruang sisi datar disalah satu SMP Kota Batu. Penelitian yang akan dilaksanakan menggunakan penelitian kualitatif deskriptif. Subjek dalam penelitian ini yaitu pendidik dan peserta didik kelas VII-B pada salah satu SMP di Kota Batu ini. Peserta didik ini dipilih karena cenderung mudah bosan dan kurang tertarik pada pembelajaran matematika. Teknik pengumpulan data yang digunakan dalam penelitian ini terdiri dari tiga, yaitu: observasi, data tes dan dokumen. Instrumen penelitian yang digunakan yaitu lembar observasi keterlaksanaan pembelajaran matematika berbasis proyek, dan lembar soal tes hasil belajar peserta didik. Secara keseluruhan pelaksanaan metode pembelajaran matematika berbasis proyek sudah terlaksana sesuai perencanaan. Aktivitas pendidik yang berhubungan dengan pembelajaran berbasis proyek memiliki rata–rata sebesar 78% yang termasuk dalam kategori terlaksana dengan baik. Oleh karena itu pelaksanaan pembelajaran berbasis proyek ini sudah dapat dikatakan layak dan perlu dikembangkan lagi. Kata kunci: bangun ruang sisi datar, implementasi, pembelajaran matematika berbasis proyek)

Abstract

Abstract: Students' abilities can be developed through lectures, one of which is variable Calculus 2. At the University of Islam Raden Rahmat (UNIRA), Malang students only rely on one textbook only when the lectures, so the motivation and low student interest in learning. Therefore it takes lecture materials that can help facilitate students in the lecture, which is an android textbook. This study aims to develop an android textbook valid, practical, and effective in Calculus 2 subjects in UNIRA Malang. This study is a research development. This textbook was developed by using the 4D model (define, design, develop, and disseminate). Phase disseminate not done. The data was collected with the validation and testing of the textbook. The textbook is validated by the lecturer and expert Calculus 2, as well as Indonesian lecturers. Tests were carried out on Informatics students UNIRA Malang to know the practical and effectiveness of the textbook. The results showed that: 1) textbooks have been effective, 2) including the content and construct validity of the validator's point of view, and 3) the use of textbooks in the lecture did not experience significant barriers.Keywords: Calculus 2, Android, Textbook. AbstrakKemampuan mahasiswa dapat dikembangkan melalui perkuliahan, salah satunya yaitu pada materi Kalkulus 2. Di Universitas Islam Raden Rahmat (UNIRA) Malang mahasiswa hanya mengandalkan satu buku ajar saja saat perkuliahan, sehingga motivasi dan minat belajar mahasiswa rendah. Oleh karena itu dibutuhkan suatu bahan perkuliahan yang dapat membantu memudahkan mahasiswa dalam perkuliahan, yaitu buku ajar android. Tujuan penelitian ini yaitu mengembangkan buku ajar android yang valid, praktis dan efektif pada mata pelajaran Kalkulus 2 di UNIRA Malang. Penelitian ini merupakan penelitian pengembangan. Buku ajar ini dikembangkan dengan menggunakan model 4D (Define, Design, Develop, and Desseminate). Fase desseminate tidak dilakukan. Pengumpulan data dilakukan dengan validasi dan pengujian buku ajar. Buku ajar ini divalidasi oleh dosen dan ahli Kalkulus 2, serta dosen Indonesia. Tes dilakukan pada mahasiswa Informatika UNIRA Malang untuk mengetahui kepraktisan dan keefektifan buku ajar. Hasil penelitian menunjukkan bahwa: 1) buku ajar sudah efektif, 2) meliputi validitas isi dan konstruk dari sudut pandang validator, dan 3) penggunaan buku ajar dalam perkuliahan tidak mengalami hambatan yang berarti.Kata Kunci: Kalkulus 2, Android, Buku Ajar.

Abstract

AbstractStudents' abilities can be developed through lectures, one of which is variable Statistics. For the maximum tuition required of a material that can support course lectures. In Universitas Islam, Raden Rahmat, students only rely on one textbook only when the lectures, so the motivation and low student interest in learning. One way that can help make it easier for students is the use of textbooks using R software. This research aims to develop textbooks using R software that is valid, practical, and effective in statistics subjects in Universitas Islam Raden Rahmat. This study is a research development. This textbook was developed using the 4D model (define, design, develop, and disseminate). Phase disseminate not done. The data was collected with the validation and testing of the Textbook. The textbook is validated by the lecturer and expert statistics, as well as Indonesian lecturers. Tests were carried out on mathematics education students at Universitas Islam Raden Rahmat to know the textbook's praktikalitas and effectiveness. The results showed that: 1) Textbook is valid (including the content and construct validity) of the validator's point of view, 2) the use of Textbook in the lecture did not experience significant barriers. According to students and lecturers, the book is a practical work, and 3) Textbooks have been effective. This is evident from the activities of students and high motivation to learn after the lecture. Keywords: Development, Statistics, Text Book. AbstrakKemampuan mahasiswa dapat dikembangkan melalui perkuliahan, salah satunya pada mata kuliah  Statistik a.

Abstract

Learning activities are an effort to increase the potential of students through a series of planned activities. One of the efforts that teachers can make so that the learning process can take place well and can achieve learning objectives is to develop teaching materials. One of the teaching materials that can be developed is the Student Worksheet. Student worksheets are arranged to make it easier for students to complete tasks in learning. In learning, especially mathematics, the independence and activeness of students in learning are factors that influence success in learning. To increase the activeness and independence in this research apply the inquiry method. The stages used in the development of teaching materials in the form of student worksheets (LKS) are research and development with the Borg and Gall model.
