MODEL PEMBELAJARAN TUTOR SEBAYA UNTUK MENINGKATKAN KEMAMPUAN KOMUNIKASI REPRESENTASI MATEMATIS MAHASISWA CALON PPL-2

Penelitian ini dilatarbelakangi oleh kondisi mahasiswa calon PPL2 bahwa  lebih dari 65% mahasiswa tersebut kompetensi matematika sekolah menengah belum pada standar yang diharapkan (paling tidak 75% mahasiswa memiliki kompetensi dalam katagori baik). Temuan tersebut terungkap dari beberapa catatan informasi di lapangan, hasil pra-survey dan hasil wawancara. Beberapa penyebab dari kondisi mahasiswa tersebut, diantaranya: (1) dalam perkuliahan matematika sekolah menengah mahasiswa menyelesaikan dengan cara kurang mandiri; (2) beberapa materi kuliah penunjang (geometri, aljabar, dan trigonometri) tidak dikuasai dengan baik oleh kebanyakan mahasiswa, dan (3) mahasiwa yang memiliki potensi di atas rata-rata kurang diberdayakan. Pelaksanaan kegiatan model pembelajaran tutor sebaya pada mahasiswa prodi pendidikan matematika FKIP Untan dilakukan sesuai langkah penelitian pengembangan ADDIE, dan langkah yang cukup menantang adalah pada langkah development, karena pada langkah ini memperoleh kelemahan mahasiswa yang beragam sehingga pengembangan tingkat lanjut perlu kreativitas yang memadai. Ketiga, Kemampuan komunikasi  dan representasi matematis mahasiswa prodi pendidikan matematika FKIP Untan sesudah pengembangan model pembelajaran tutor sebaya, berada di atas standar; yakni rata-rata skor tes I sebesar 72,1 dan rata-rata skor tes II sebesar 77,4. Melalui pengembangan model pembelajaran terjadi perubahan prinsip belajar pada diri mahasiswa yang memperoleh kontribusi dari penguatan karakter tanggungjawab, kepedulian dan solidaritas

Deskripsi Proses Pembelajaran IPAS Dengan Memanfaatkan Teknologi Informasi dan Komunikasi di Sekolah Dasar Negeri 28 Pontianak Kota

This research was conducted to describe the science learning process in utilizing Information and Communication Technology. This study used descriptive qualitative method. The sample is 2 teachers in class IV SDN 28 Pontianak City. Data collection techniques used are observation and interviews. The research data analysis technique uses the Miles and Huberman model. The results showed the implementation of science learning using ICT, in the core learning activities the teacher used ICT more often, in the preliminary and closing activities of learning only occasionally. Intensity Utilization of teachers looks enthusiastic and the number of applications using power point only. Teachers have obstacles in utilizing ICT, such as a lack of facilities and infrastructure, for example ICT devices that are lacking to operate properly, lack of technicians, lack of time in teaching due to too long to install ICT devices and lack of funding to facilitate computer labs . The solution is the school must improve infrastructure better, provide ICT facilities in each class and provide regular teacher training. Can be concluded that the implementation of science learning by utilizing ICT, teachers are more dominant in using it in the core learning activities
