Abstract

This study aims to test the feasibility of media-based learning Blog in learning mathematics on trigonometric subjects. This development research uses 8 stages from 10 stages of borg and gall method that are potential and problem, data collection, product design, product validation, product revision, product test, product revision and mass production. Learning media blogs are developed with the help of adobe flash which aims to provide some animation. This research was conducted in SMA Negeri 1 Batanghari class X students. The assessment instrument used was questionnaire of feasibility test by media expert, Expert of Material, and Questionnaire of student response. The results of the research are: 1) Based on the validation of material expert judgments obtained an average score of 4.65 is located in the category of "Very Good". Validation of expert media judgment obtained an average score of 4.35 in the category of "Very Good". Validation of the linguists assessment obtained an average score of 4.5 that is in the category of "Very Good". In addition, the results of small-scale test responses of learners obtained a score of 4.23 on the criteria of "Very Good", and while on a large-scale test the learners response to get an average score of 4, 19 is on the criteria of "Good". Thus it can be concluded learning media berbantuan blog is in good category and can be used in learning, especially on Trigonometry material.

Abstract

The aim of this research is to find out whether the improvement of students adaptive reasoning ability with accelerated learning method is better than ordinary learning. This research is a quasi experiment or quasi-experimental design with pretest-posttest control group design. The sampling technique uses a class random technique. The implementation of this study was carried out on eighth grade students in one of the State Junior High Schools in Bandar Lampung. The questions given are questions of adaptive reasoning ability in relation and function material, the test of adaptive reasoning ability test is theoretically tested by the validator with the description that test questions can be understood well and empirically validity and reliability meet the characteristics to be used in research , the level of difficulty and distinguishing power of the problem can already be used to determine the improvement of adaptive reasoning abilities. Quantitative data analysis was carried out using a mean difference test and N-Gain test. The results of this study were students whose learning to apply learning with the accelerated learning method improved adaptive reasoning ability was significantly better compared to students whose learning using ordinary learning was reviewed thoroughly.

Abstract

Kemampuan komunikasi matematis merupakan kompetensi yang harus dimiliki siswa, namun kenyataan di lapangan menunjukkan bahwa kemampuan komunikasi matematis masih belum memuaskan.  Pembelajaran konflik kognitif diterapkan dengan harapan untuk meningkatkan kemampuan komunikasi matematis siswa. Tujuan pada penelitian ini adalah untuk menelaah peningkatan kemampuan komunikasi matematis  siswa yang menerapkan pembelajaran konflik kognitif dan pembelajaran biasa, mengkaji perbedaan peningkatan kemampuan komunikasi matematis siswa yang menerapkan pembelajaran konflik kognitif dan siswa yang mendapat pembelajaran biasa bila ditinjau dari kategori pengetahuan awal matematika (tinggi dan rendah).Penelitian ini merupakan penelitian quasi experiment atau eksperimen semu dengan desain kelompok kontrol non-ekuivalen. Pelaksanaan penelitian ini dilakukan pada siswa kelas XIPA di salah satu SMA Swasta di Bandung. Soal-soal yang diberikan adalah soal-soal kemampuan komunikasi matematis pada materi trigonometri, uji coba tes kemampuan komunikasi matematis diuji secara teoritik oleh validator dengan gambaran bahwa soal tes dapat dipahami dengan baik dan secara empirik validitas dan reliabilitas memenuhi karakteristik untuk digunakan dalam penelitian, tingkat kesukaran dan daya pembeda soal sudah bisa membedakan siswa berkemampuan tinggi dan siswa berkemampuan rendah.  Analisis data kuantitatif dilakukan dengan menggunakan uji perbedaan rataan dan uji Anova dua jalur.Hasil penelitian ini adalah siswa yang pembelajarannya menerapkan pembelajaran konflik kognitif peningkatan kemampuan komunikasi matematis secara signifikan lebih baik dibandingkan dengan siswa yang pembelajarannya menggunakan pembelajaran biasa ditinjau secara keselurahan.
