Mathematic is one of the difficult and scary subjects. Sometimes, the students feel afraid and it makes them feel forced and uncomfortable. Indirectly this situation would affect the students’ learning outcomes and another reason was the lack of activities in learning mathematics which could train and enhance students’ collaborative skill. Learning would be more meaningful if it involved peers to build students’ knowledge. Therefore, the purpose of this research was to find out the effect of Ludo game in improving students’ collaborative skill. This research was quasi-experimental with the sample of 21 students on third grade in SD 19 Nan Sabaris. The instrument used students’ collaborative assessment sheet. The data analyzed by using effectiveness test with paired sample t-test. The conclusion showed that there were significant different on students’ collaborative skill between the students who were taught by using Ludo and the students who were taught by using conventional learning.

Learning tool is a guide line teacher inconducting teaching and learning process in the class. The aim of this research is to develop a learning tool of physics-based thinking skill in problem basedAbstrak: Perangkat pembelajaran adalah acuan guru dalam melaksanakan pembelajaran di kelas. Penelitian ini bertujuan untuk mengembangkan perangkat pembelajaran fisika berbasis keterampilan berpikir kritis dalam problem-based learning dengan kriteria valid, praktis, dan efektif. Jenis penelitian adalah penelitian pengembangan. Model pengembangan yang digunakan adalah model 4-D yang terdiri dari tahap pendefinisian, perancangan, pengembangan dan penyebaran. Uji coba produk dilakukan di kelas XI MIA 1 SMA Adabiah 2 Padang dan penyebaran dilakukan di kelas XI MIA 2 SMA Adabiah 2 Padang. Instrumen yang digunakan adalah lembar validasi dan lembar observasi. Jenis data yang diambil aktifitas dan hasil belajar siswa. Hasil tahap pendefenisian diperoleh melalui analisis kurikulum, konsep dan siswa. Hasil tahap perancangan diperoleh dari perancangan perangkat pembelajaran. Hasil tahap pengembangan sangat valid, hasil uji praktikalitas sangat praktis, hasil analisis efektivitas sangat efektif dan terlihat dari nilai pengetahuan 86,67% memperoleh nilai tuntas, penilaian keterampilan 86,07% memperoleh nilai tuntas dan penilaian sikap 80,23% bersikap baik. Dengan demikian penelitian ini menghasilkan perangkat pembelajaran fisika berbasis keterampilan berpikir kritis dalam PBL dengan kriteria sangat valid, sangat praktis dan efektif. © 2017 Pendidikan Fisika FTK UIN Raden Intan LampungKata kunci: keterampilan berpikir kritis, perangkat pembelajaran, problem based learning, strategi pembelajaran

Science is one of the compulsory subjects at the elementary school level. Science learning is currently not able to motivate students to be active in learning, and this can be observed at SDN 19 Nan Sabaris. This study aims to see the effect of using problem-based LKPD with the help of applications to improve science learning motivation of fifth grade students of SDN 19 Nan Sabaris. This type of research is quasi-experimental, with a sample of fifth grade students at SDN 19 Nan Sabari, Padang Pariaman Regency. The instrument of data collection in the study was a motivational questionnaire. The data analysis technique uses the t test with the type of paired sample t-test. The results of the data analysis showed the value of sig 2. Tailed for 0.0025 smaller than the alpha value = 0.05, and it can be concluded that there is a significant difference in science learning motivation between before and after the use of problem-based LKPD.
