This study aims to determine the comparison of students 'mathematical representation ability through the Project Based Learning (PjBL) Model and the students' mathematical representation ability through the conventional model. The PjBL model is a student-centered, innovative, project-based learning model and positioned teachers as effective facilitators in the contextual learning related to real life situation. This research employed quasi-experimental design. The research applied the posttest only non-equivalent control group design through randomized cluster sampling. The data collection technique used was test. The instrument used to collect the data was the essay test. Data analysis was conducted using independent sample t-test. The result of the data calculation through the Independent-Sample T-Test test obtained the significance level of 0.913 means that the students’ mathematical representation ability was better after the learning through Project Based Learning (PjBL) model was conducted compared to the students' mathematical representation ability through a conventional model. This means that the PjBL model is more influential on students' mathematical representation ability.
Penelitian ini bertujuan untuk menghasilkan e-modul matematika berbasis open ended yang berkualitas dilihat dari kevalidan, kepraktisan dan keefektifan. Penelitian ini dilakukan di SMP Muhammadiyah 3 Bandar Lampung. Penelitian ini merupakan jenis penelitian dan pengembangan (Reseach and Development). Langkah-langkah penelitian dan pengembangan berpedoman pada model ADDIE (Analysis, Design, Development, Implementation dan Evaluation). Penelitian ini dilatar belakangi oleh masalah yaitu belum adanya media pembelajaran yang menarik yang digunakan pendidik dan masih beranggapan matematika itu sulit dan membosankan. Hasil pengembangan diperoleh tahap analisis yaitu analisis kurikulum, analisis kebutuhan, dan analisis karakteristik peserta didik. Pada tahap desain diperoleh pemilihan media, pemilihan format dan desain awal. Pada tahap pengembangan dilakukan pengembangan media dan penilaian aspek kevalidan. Pada tahap implementasi dilakukan uji coba dalam kelas pembelajaran dan tes. Tahap evaluasi dilakukan analisis kepraktisan dan keefektifan. Hasil penelitian penelitian menunjukan bahwa e-modul matematika yang dikembangkan memenuhi kriteria valid, praktis dan efektif. Modul matematika dinyatakan valid berdasarkan penilaian para ahli materi dan pendidik menunjukan angka 3,29 dengan kriteri “Valid”, penilaian untuk para ahli media dan pendidik menunjukan angka 3,27 dengan kriteria “Valid”. Untuk hasil respon peserta didik uji coba skala kecil memperoleh rata-rata 3,30 dengan kriteria “Sangat Menarik” dan untuk uji coba skala besar diperoleh rata-rata 3,28 dengan kriteria “Sangat Praktis”. E-modul dikatan efektif berdasarkan ketuntasan peserta didik sebesar 68% yang termasuk kategori “Efektif”. Dapat disimpulkan emodul matematika layak digunakan.
This study aims to develop modules based on the Multiple Intelligences Theory of Howard Gardner using the Realistic Mathematics Education (RME) approach in class VIII Middle School. This research is an R & D research which stages using the development of Borg and Gall. The instrument used in this study uses a questionnaire given to material experts and media experts to test the feasibility of this module. The research results that have been developed are feasible to be used in proper learning are used seen from the results of the validation of material experts and media experts. On the results of the media expert test obtained an average of 80% with the Criteria "Good" while the results of the material expert test obtained an average value of 84% with the criteria "Very Good". Student responses to the small group test obtained an average value of 79% with the criteria "Good", while the response of students in the field test obtained an average value of 88% with the criteria "Very Good". Abstrak: Penelitian ini bertujuan untuk mengembangkan modul berbasis Teori Multiple Intelligences Howard Gardner menggunakan pendekatan Realistic Mathematics Education (RME) di kelas VIII SMP. Penelitian ini merupakan penelitian R&D yang tahapannya menggunakan pengembangan Borg and Gall. Instrumen yang digunakan dalam penelitian ini menggunakan angket yang diberikan kepada ahli materi dan ahli media untuk menguji kelayakan modul ini.Hasil penelitian yang telah dikembangkan layak digunakan dalam pembelajaran layakdigunakandilihat dari hasil validasi ahli materi dan ahli media. Pada hasil uji ahli media diperoleh rata-rata sebesar 80% denganKriteria “Baik” sedangkan pada hasil uji ahli materi diperoleh nilai rata-rata sebesar 84% dengankriteria “BaikSekali”. Adapun respon siswa pada uji kelompok kecil diperoleh nilai rata-rata sebesar 79% dengan kriteria “Baik”, sedangkan respon siswa pada uji lapangan diperoleh nilai rata-rata sebesar 88% dengan kriteria “Baik Sekali”.
This research is a development research aimed at developing powtoon-assisted learning media, knowing student responses, and effectiveness. The procedure in this development uses a 4-D development model, namely: Define, Design, Develop, and Disseminate. The product developed was in the form of a learning media video on a two-variable linear equation system material for VIII grade students. The instruments used in this study are learning media assessment sheets by experts to measure the validity of learning media, student response questionnaires to measure the attractiveness of learning media, as well as learning outcomes tests to measure the effectiveness of the use of instructional media.
