Abstract

The development of IT in the 21st century has become the main complement in every learning activity such as using learning media. Learning media is a tool that can help the learning process so that learning objectives are conveyed. This study aims to produce interactive learning media using Sparkol Videoscribe on valid algebraic function limits. This research is a Research and Development (R&D) research with a four-D (4-D) development model. The subjects in this study were students of class XI IPS 1 SMAN 12 Padang. The data collection technique used a validation sheet. The results of this study are: Validity of interactive learning media using Sparkol Videoscribe which is designed to be very valid with the percentage results obtained 95.99% with a very valid category. Based on the results of the study, it can be concluded that the validity of interactive learning media using Sparkol Videoscribe is valid and feasible to use on the material limit of algebraic functions for class XI IPS 1 SMAN 12 Padang.

Abstract

The difficulty of learning to build polyhedron for middle students makes experts lecturers collaboratively create learning trajectories through the Lesson Study for Learning Community (LSLC). This study aims to produce a learning trajectory that can assist students in learning polyhedron using collaborative learning through LSLC. The research method used was design research with the first stage, preparing for experiment, experimental design, and retrospective analysis. This learning approach uses collaborative  LSLC is used in the process of making teaching materials and along with research methods. This study involved 47 lecturers and 24 mathematics education students. Data collection was carried out through observing student activities, recording video events in class, collecting student work results, and student test results. The collected data were then analyzed retrospectively with the results showing that collaborative and LSLC used in the acquired learning paths can help students in learning flat-sided shapes. The learning trajectory includes (1) students can collaboratively understand the surface area of the cube (2) collaboratively, students can understand the space diagonal of a block. With the existence of LSLC, researchers can form learning communities with research subjects, collaborate in making learning designs and teaching materials, and produce multilevel effective learning through sharing tasks and jumping tasks

Abstract

Proses belajar yang masih menggunakan metode konvensional dan menggunakan media papan tulis, serta siswa yang sulit memahami materi yang ada pada buku cetak. Tujuan penelitian ini adalah untuk menghasilkan e-Modul berbasis RME berbantuan Flip PDF Professional yang valid dan praktis pada materi barisan dan deret Fase-E di SMAN 1 Ranah Pesisir sehingga dapat digunakan sebagai salah satu sumber belajar matematika khususnya materi barisan dan deret. Jenis penelitian ini adalah penelitian pengembangan (Research and Development/ R&D) dengan model pengembangan yang dikemukakan oleh Plomp. Tahapan yang digunakan dalam model pengembangan ini hanya tahap 1 sampai dengan tahap 2 yaitu tahap investigasi awal, prototyping phase yang merangkap uji validitas dan praktikalitas. Instrumen penelitian yang digunakan adalah angket validitas, angket uji satu-satu yang berguna untuk melihat kepraktisan e-Modul oleh guru, angket uji kelompok kecil yang berguna untuk melihat kepraktisan e-Modul oleh siswa. Berdasarkan penilaian validator, diperoleh hasil validitas e-Modul berbasis RME berbantuan Flip PDF Professional sebesar 82,6 % dengan kategori sangat valid. Nilai kepraktisan dengan guru memperoleh nilai akhir 86,7 % dengan kategori sangat praktis. Nilai kepraktisan dengan siswa memperoleh nilai akhir 86,7 % dengan kategori sangat praktis. Berdasarkan hasil penelitian dapat disimpulkan bahwa e-Modul berbasis RME berbantuan flip pdf professional pada materi barisan dan deret Fase-E di SMAN 1 Ranah Pesisir dinyatakan valid dan praktis untuk digunakan oleh guru dan siswa.
