ABSTRAKProgram International for Student Assessment (PISA) merupakan program penilaian tingkat Internasional yang diselengarakan setiap tiga tahun sekali yang bertujuan untuk meneliti kemampuan siswa usia 15 tahun dalam literasi membaca, matematika, dan sains. Hasil PISA tahun 2009 dan tahun 2013 menunjukkan bahwa prestasi siswa Indonesia pada literasi matematika masih berada pada level 2. Rendahnya prestasi tersebut tidak terlepas dari proses belajar di sekolah, salah satunya siswa belum dibiasakan menyelesaikan soal-soal yang menuntut kemampuan siswa untuk menganalisis, bernalar, beragumentasi, merepresentasikan permasalahan dalam berbagai situasi, dan memecahkan masalah yang berhubungan dengan masalah kehidupan sehari-hari. Untuk itu perlu dikembangkan soal matematika setara PISA yang sesuai dengan konteks siswa Indonesia yang dapat digunakan guru sehingga literasi matematika siswa dapat meningkat. Tujuan penelitian ini adalah (1) untuk menghasilkan soal matematika setara PISA pada konten shape and space dan change and relationships untuk siswa SMP yang valid dan praktis dan (2) untuk mengetahui level siswa dalam menyelesaikan soal matematika setara PISA pada konten shape and space dan change and relationships. Penelitian ini menggunakan alur pengembangan instrumen oleh Tessmer. Subjek penelitian adalah 36 siswa kelas IX-5 MTsN Model Banda Aceh. Hasil penelitian menunjukkan bahwa (1) diperoleh perangkat soal matematika setara PISA pada konten shape and space dan change and relationship sebanyak 12 butir yang valid dan praktis dan (2) rata-rata pencapaian level siswa dalam menyelesaikan soal matematika setara PISA masih berada pada level 2.ABSTRACTProgram for International Student Assessment (PISA) is a study of the International level student assessment program is held from once every three years which aims to examine the ability of 15 year old students in reading, mathematics, and science literacy. The PISA results in 2009 and 2013 showed that Indonesia student's achievements in mathematics literacy is still at the lower level. Low achievement is closely connected to the learning process in schools, such as students are not accustomed to solve the problems which require the student's ability to analysing, reasoning, arguing, and representing problems in a variety of situations and solving problems related to their daily life. Therefore, it is necessary to develop the equivalent of PISA mathematical problems in Indonesian context so that teachers can increase the studentsâ€™ mathematical literacy. The purpose of this study was (1) to produce the equivalent PISA mathematical problem on the shape and space and change and relationships for junior high school students that fulfill the validity and practicality criteria, and (2) to determine the level of students in solving mathematical problems similar to the content of PISA. Tessmer development design was used in this study. The subjects were 36 students grade IX-5 MTsN Model Banda Aceh. The results showed that (1) obtained the equivalent PISA mathematical problem on the shape and space and change and relationships content as much as 12 items are fulfill the validity and practicality criteria (2) The average of studentsâ€™ achievement in level of students in solving mathematical problems PISA equivalent is at the baseline of level 2 (siswa yang mana? Semua siswa? Pada umumnya, atau rata-rata?).

The application of Realistic mathematics education (RME) in schools has not satisfied. The efforts of educators to help teachers implement RME are an ongoing process, including by providing examples of learning process through the video lessons. This study aims to investigate teacher understanding of the characteristics of RME through watching video lessons. Three elementary school teachers in Aceh, Indonesia, were involved in this research. Data was collected through questionnaires and semi-structured interviews. Data were analyzed descriptively. The results showed that the teacher did not understand three of the five characteristics of RME. Teachers' understanding of real problems is only limited to the use of concrete objects. The teacher could not identify activities on the video about using models or symbols to scaffold students from concrete to more formal knowledge. The teacher also did not realize that the relationship between mathematical concepts can help students understand mathematics well. The implication of this study is that researchers need to guide the teacher design the learning trajectory before watching learning from other teachers. After watching the whole video lessons, the teacher also needs to be moved to identify important events related to the characteristics of RME in the learning in the video.

The development of technology in education greatly influences learning strategies. Thus, teachers must adapt and present interesting and technology-based learning, such as e-comics. Therefore, the teacher must see in advance the extent to which students will accept e-comics for use in learning mathematics. This research aimed to determine students' perceptions of the use of e-comics as a media in mathematics learning. This research implemented a quantitative approach with a survey method. The samples were 124 students of Junior High Schools (SMP / MTs) in Aceh. The research data were obtained from questionnaires filled by students which were collected through the TAM (Technology Acceptance Models) framework which was distributed online. The results showed that students used e-comic as a learning media influenced by their perceived benefits and attitudes towards the use of e-comic. The perceived benefits of students' attitudes have a significant role in their behavioral intention to use e-comic in learning mathematics. This research implies that e-comics has the potential to be used as a media in mathematics learning, especially on material that is considered difficult so that it can attract students' attention.

The purpose of this study was to determine the ability of students as prospective teachers to solve problems of high-level PISA (most difficult) is level 5. This study was a descriptive study using a qualitative approach to describe the ability of each student in solving PISA question. The subjects were students taking the Teaching Mathematics I course of Mathematics Education Program FKIP Unsyiah. Data analysis in qualitative research based on the results of the data collection process in the form of field notes, documentation, and interviews. Assessment conducted on students' ability to solve problems using the PISA assessment rubric. Furthermore, the score obtained is converted into the interval level of ability. The results showed only one student (14,28 %) of the seven students who have an excellent ability to resolve the matter appropriately. Meanwhile, three students (42,85 %) experienced only a mistake on the problems at the problem of the distance down. However, the ability of the three students vary based on the accuracy of the analysis in solving aspects. For the third ability of other students (42,85 %) were still low due to the settlement of questions that do not quite right with the ability to be at sufficient levels. Based on the results of this study are expected each faculty can use international issues as a matter of PISA in learning, so that students get used to solve the problems of non-routine to improve their ability to understand and solve problems, which can contribute to the future of teaching practice.
