The Covid-19 pandemic caused learning activities to immediately stop and be diverted online. There are many obstacles faced by teachers and students. Therefore, it is necessary to choose the right learning media so that the learning process remains optimal. One media that can be used as a learning media is a website. This study aims to describe the effectiveness of the website as a media for learning mathematics during the online learning period. This type of research is descriptive quantitative with survey method. The sample in this study were 15 students of class VIII SMP Nurul Falah Pekanbaru who were selected by simple random sampling technique. Data obtained using google form which contains statements related to 5 aspects of website assessment, clarity of material, interactivity, accessibility, nature of efficiency, and effectiveness. The results obtained by the majority of students like the website as a medium for learning mathematics. The effectiveness of using the website was in the quite good category, 40% of students said the website was very effective, 53,3% said it was effective, and only 6,7% said it was ineffective. Based on this, the website becomes an effective learning medium to be used during the online learning period.
In March 2020, direct learning activities were transferred online due to the Covid-19 pandemic. There are many alternative technology-based learning media used for online learning systems. However, the use of this media has not been able to increase students' motivation to learn mathematics. One of the media that can be used as an alternative learning media during this pandemic is a website. The purpose of this study was to find out how to use the website as a learning media in the midst of this pandemic, and to determine student learning motivation. This research is a descriptive study with a quantitative approach, the subjects in this study were 25 students of grade 8 and 9 Junior High School. The results of this study were that many students agreed with the use of websites as alternative learning media during this pandemic and students' high motivation to learn mathematics when using the website with an average percentage of 66,3%. From this research, it can be concluded that the website can be an alternative media for learning mathematics in the midst of this pandemic because the website has various advantages that can also increase student learning motivation.
Penelitian ini bertujuan untuk mendeskripsikan: (1) keterlaksanaan pembelajaran fisika di SMA dengan penerapan model pembelajaran kooperatif tipe TAI, (2) peningkatan hasil belajar siswa berdasarkan kompetensi pengetahuan, sikap, dan keterampilan, (3) respons siswa terhadap model pembelajaran yang diterapkan, dan (4) aktivitas siswa. Penelitian ini adalah penelitian quasi experiment dengan “One Group Pre-test Post-test Design” pada 1 kelas eksperimen dan 2 kelas replikasi, masing-masing kelas berjumlah 36, 37 dan 35 siswa. Data diperoleh melalui observasi, pemberian soal pre-test dan soal post-test, serta angket respon siswa. Hasil belajar siswa pada kompetensi pengetahuan dilakukan dengan uji-t berpasangan, analisis n-gain score dan uji ANOVA. Hasil penelitian menunjukan bahwa: (1) penerapan model pembelajaran kooperatif tipe TAI terlaksana dengan kategori baik; (2) hasil belajar siswa pada kompetensi pengetahuan meningkat secara signifikan pada α=0.05 dengan n-gain score untuk kelas eksperimen sebesar 0,48, kelas replikasi I sebesar 0.51, dan kelas replikasi II sebesar 0.42 seluruhnya dalam kategori sedang, dan peningkatan hasil belajar siswa pada ketiga kelas tersebut secara statistik tidak berbeda. Pada kompetensi sikap diperoleh nilai modus pada ketiga kelas sebesar 3.00 dan termasuk dalam kategori baik. Untuk kompetensi keterampilan, diperoleh nilai rata-rata untuk penilaian kinerja dan tertulis kelas eksperimen sebesar 3.73, kelas replikasi I sebesar 3.72 dan replikasi II sebesar 3.71; (3) hasil pesentase rata-rata respons siswa terhadap model pembelajaran kooperatif tipe TAI positif dengan kategori sangat baik; dan (4) aktivitas siswa mengalami peningkatan selama pembelajaran berlangsung.
Penelitian ini bertujuan untuk mengembangkan buku ajar untuk memfasilitasi mahasiswa pada perkuliahan Dasar dan Proses Pembelajaran Matematika (DPPM) yang memenuhi kelayakan yakni memiliki kriteria valid dan praktis. Penelitian ini merupakan penelitian pengembangan dengan model pengembangan dari Plomp. Prosedur pengembangan terbagi menjadi tiga tahap yakni: (1) studi pendahuluan; (2) pengembangan atau pembuatan prototipe; dan (3) penilaian. Pengumpulan data menggunakan lembar angket kevalidan dan kepraktisan buku ajar. Subjek penelitian ini adalah mahasiswa calon guru program studi pendidikan matematika semester IV, dan dosen pendidikan matematika di Pekanbaru. Hasil penelitian ini menunjukkan bahwa, berdasarkan hasil dari komentar para validator buku ajar yang dikembangkan telah valid dengan kriteria baik, baik dari aspek konten, media, maupun bahasa. Selanjutnya berdasarkan ujicoba terbatas, buku ajar yang dikembangkan telah terbukti praktis dengan kategori baik. Hasil ini dapat dilihat berdasarkan masukan dan komentar beberapa mahasiswa yang menjadi subjek ujicoba bahwa, isi materi dan bahasa mudah dipahami, kalimat sederhana dan adanya ringkasan disetiap BAB nya sangat mendukung proses perkuliahan.Kata kunci: Buku ajar; dasar dan proses pembelajaran matematika; pengembangan.
