ABSTRACTThis research is motivated by the fact that the ability of mathematical communication in Indonesia is low. The models and approaches used in the learning process are one of the supporting factors for learning mathematics in the classroom. This study aimed to analyze SMA 1 Namlea students' mathematical communication skills with realistic mathematics learning assisted by GeoGebra. The research method used is quasi-experimental. WHO researched SMA Negeri 1 Namlea, Buru Regency. The analysis results show that the test instrument is valid and reliable to be used for pretest and posttest. The results showed that the mathematical communication of students who received realistic mathematics learning assisted by GeoGebra was better than students who received realistic mathematics learning without GeoGebra. The results also showed that there was a positive response from students towards learning realistic mathematics with GeoGebra.KEYWORDS: Realistic Mathematics, GeoGebra & Mathematical Communication

Based on the explanation of the theory by Gardner the state is motivation comes from within a person as a driving force to achieve goals for more advanced change. This study aims to determine how enthusiastic student's Eighth grade in the SMPN 03 Bengkulu Tengah are in learning English, especially speaking English. Researchers used a quasi-experimental research method, namely a control group posttest only design which showed a significant difference between 74, 92%, and 61.96% of the experimental class in the control class. From this hypothesis, the researcher obtained a comparison of the experimental class in the treatment using the storytelling method of 4.34% and the control class with the narrative picture method of 3.58%. So the researcher can conclude that there is a significant difference between the two methods with or without the use of treatment compared to the motivation to learn English in class VIII students at SMPN 03 Bengkulu Tengah.

ABSTRAK Penelitian ini bertujuan untuk melihat pengaruh model pembelajaran berbasis masalah yang dikombinasikan dengan menulis matematika terhadap kemampuan pemecahan masalah dengan tinjauan kemampuan awal matematis siswa dengan kategori tinggi, sedang, dan rendah. Penelitian ini merupakan penelitian kuasi eksperimen dengan menggunakan satu kelompok eksperimen dengan perlakukan model pembelajarann berbasis masalah yang dikombinasikan dengan menulis matematika dan satu kelompok kontrol yang hanya diberikan perlakukan model pembelajaran berbasis masalah. Metode pengumpulan data terdiri dari tes kemampuan pemecahan masalah matematis. Teknik analisis data menggunakan analisis variansi dua jalan sel tidak sama. Hasil penelitian menunjukkan bahwa kemampuan pemecahan masalah siswa yang menggunakan model pembelajaran berbasis masalah yang dikombinasikan dengan menulis matematika lebih baik daripada kemampuan pemecahan masalah siswa yang hanya menggunakan model pembelajaran berbasis masalah secara umum maupun berdasarkan kategori kemampuan awal matematis. Ditinjau dari kategori kemampuan awal matematis, siswa kategori tinggi dan sedang menunjukkan tidak adanya perbedaan kemampuan pemecahan masalah yang signifikan, sedangkan kemampuan pemecahan masalah siswa kategori tinggi dan sedang lebih baik jika dibandingkan dengan kemampuan pemecahan masalah siswa kategori rendah. Kata kunci: pembelajaran berbasis masalah, menulis matematika, kemampuan pemecahan masalah, kemampuan awal matematis.   ABSTRACT This study aims to look at the effect of problem-based learning models combined with mathematical writing on problem solving abilities with a review of students' mathematical early capabilities in high, medium, and low categories. This research is a quasi-experimental study using one experimental group with the treatment of problem-based learning models combined with writing mathematics and a control group that is only given the treatment of problem-based learning models. Data collection methods consist of tests of mathematical problem solving abilities. Data analysis techniques using two path analysis of variance are not the sam cell. The results showed that the problem-solving ability of students who use problem-based learning models combined with writing mathematics is better than the problem-solving abilities of students who only use problem-based learning models in general or by the category of mathematical early ability. Judging from the early mathematical ability category, high and medium category students showed no significant difference in problem solving abilities while the problem solving ability of high and medium category students was better when compared to the problem solving ability of low category students. Keywords: problem based learning, writing mathematics, problem solving ability, mathematics early ability.
