Kurang tertariknya siswa dalam pembelajaran. Hal ini disebabkan karena dalam penyajian materi guru masih menggunakan buku paket yang disediakan oleh sekolah, sehingga perlu dikembangkan suatu media pembelajaran matematikayang berbasis macrmedia flash 8. Penelitian ini bertujuan untuk mengembangkan media pembelajaran matematika berbasis macromedia flash 8 dengan pendekatan Contextual Teaching andLearningMateri pada materi Bangun Ruang Kelas V SDN 55 Padang. Penelitian ini adalah penelitian pengembangan. Penelitian ini dilakukan pada semester genap 2019/2020 dengan subjek penelitian siswa kelas VB SD N 55 Aia Pacah Padang. Hasil penelitianmenunjukannilairata-ratavaliditas 96,3% dengan kriteria sangat valid, nilai rata-rata praktikalitas 94,1% dengan kriteria sangat praktis. Dari data tersebut disimpulkan bahwa pengembangan media pembelajaran interaktif bangun ruang tersebut sangat valid, dan sangat praktis dalam pembelajaran matematika dikelas V sekolah dasar.

This study aims to describe the learning difficulties of PGSD students in Basic Mathematics Concept II lecture which is viewed from the location, type and factor of student learning difficulties. From the results of research conducted obtained: 1.The location of learning difficulties of students in learning materials data processing on the subject of Basic Mathematics Concept II is on the indicator: determine the mean, median, and mode for single data with 75.478 percentage, 2. the types of learning difficulties experienced by students in the subject matter of the basic concept of mathematics II are the types of procedural and skill errors with each percentage of 27% and 20%. Therefore, it is important for students to understand and master the concept of the material and understand the procedures (skills) done in solving a problem.

This research aims to produce a effective module of area and perimeter plane  in primary school. This research is a research development by using the 4D model (define, design, develop, and desseminate). Phase desseminate not do. This research was to determine whether the module was designed has effective. Effectiveness module is obtained from data on student learning outcomes. The results showed that the modules of area and perimeter plane has a high effectiveness. Therefore, it was concluded that the module area and perimeter plane in primary schools has been effective.Keywords: module, area and perimeter, effective, primary school

Learning mathematics at school mostly involving mathematical reasoning abilities. Weakness in the reasoning of students in mathematics learning visible from students' mistakes in solving math problems.Efforts should be made to improve the ability of students' mathematical   reasoning   can   be   through   the   model   Problem   Based   Instrutional (PBI).Problem Based Instructional a learning that begins with the presentation of an authentic and meaningful issues that the students will be able to conduct investigations and menutut solving by the students themselves.So with the model Problem Based Instructional able to assist students in improving students' mathematical reasoning abilities.

Kementerian Pendidikan, Kebudayaan, Riset, dan Teknologi Republik Indonesia mencanangkan Program Merdeka Belajar Kampus Merdeka (MKBKM) yang merupakan salah satu terobosan di era digitalisasi di bidang pendidikan. Program MBKM ini memberi peluang untuk pertukaran pelajar dan juga membuka batas ruang kelas (fisik) menjadi ruang digital. Penelitian ini bertujuan untuk menganalisis implementasi program MBKM di Prodi Pendidikan guru sekolah dasar Universitas Bung Hatta. Selain itu, penelitian ini bertujuan untuk menganalisis berbagai kendala yang dihadapi selama pelaksanaan program MBKM. Kebijakan MBKM dimaksudkan untuk pemenuhan masa dan beban belajar bagi mahasiswa program sarjana atau sarjana terapan dengan mengikuti seluruh proses pembelajaran pada program studi (prodi) PGSD di Universistas Bung Hatta sesuai masa dan beban belajar. Mahasiswa dapat pula mengikuti proses pembelajaran untuk memenuhi sebagian masa dan di luar prodi.
