The research is aimed to: (1) Get the set of open-ended problems which are valid and practical about fraction number in the Junior High School. (2) Find out the potential effects of open ended problems in relation to students'achievement in solving open-ended problems at Junior High School. This research is a developmental research. The respondence of this research are 37 students of seventh grade at SMP Negeri 6 Sekayu. The instrument used for this research is test of open ended problems. All data have been collected was analysed qualitatively. The results show that: (1) This research produces open ended problem about fraction number for students of VII grade which are valid and practical. The validity was judged by validator, where the all validators state that the instrument have been valid based on the content, construct and face. The validity was also judge by validator in the small group. The practicality was shown by the result of validators, which most of students could solve the open-ended problems. (2)The prototype of open-ended problems which were developed has positive potential effect to the result of student achievement, and that is shown by the variety of students'answers, and the average students'positive category of 2 tests were 79,8%.

AbstrakPenelitian ini bertujuan untuk: (1) Menghasilkan media komik matematika berbasis nilai karakter pada materi trigonometri di kelas X SMA yang valid dan praktis. (2) Mengetahui efek potensial yang muncul dari pengembangan media komik matematika berbasis nilai karakter pada materi trigonometri di kelas X SMA terhadap hasil tes siswa. Jenis penelitian yang digunakan adalah Development Research tipe Formative Evaluation. Subjek penelitian ini adalah siswa kelas X-1 SMA Negeri 1 Indralaya Utara tahun ajaran 2015/2016 yang berjumlah 30 siswa. Teknik pengumpulan data adalah dengan walkthrough, observasi, dan tes. Hasil dari penelitian ini adalah: (1) Penelitian ini telah menghasilkan media komik matematika berbasis nilai karakter pada materi trigonometri di kelas X SMA yang valid dan praktis. Validitas tergambar dari hasil penilaian validator dari segi konten, konstruk dan bahasa. Praktikalitas tergambar dari hasil ujicoba small group, dimana siswa dapat menggunakan media dengan baik sesuai perencanaan. (2) Media komik matematika berbasis nilai karakter dapat meningkatkan nilai karakter siswa. (1) This research has produced a media of math comics based on character values for trigonometry material to first grade of senior high school which valid and practical. The validity drawn from the assessment result of validator in terms of content, construct, and language. Practicalities drawn from the results of a small group test where most student can well-use the media as planned. (2) Mathematics comics media based on character values can increase students character values. (3) Matematics comics media which is developed has a positive potential effect on students test results, it can be seen that the stundent achieving the Minimum Completeness Criteria {Kriteria Ketuntasan Minimum (KKM)} of 2,51 is amounted to 83 or as many as 25 students.
Mathematical learning not only produces students who succeed in mathematical and procedural calculations but also develops religious thinking. Realistic mathematics education with the context of Islamic values makes students can imagine, which is one of the right ways to develop the skills of students’ creativity, collaboration, and communication. This study aims to describe the learning trajectory that can help students understand integers with a realistic mathematics education approach based on Islamic values. It is hoped that student responses are positive, meaningful, and enjoyable. This research uses the design research method, which is a form of a qualitative approach. There are three stages in this research, namely: preliminary design, experimental design, and retrospective analysis. The results showed that the Hypothetical Learning Trajectory (HLT) trial with an Islamic value-based context showed significant progress based on student responses. Initially, students had difficulty understanding integers, but they felt delighted to follow the learning process along with the habituation. The HLT technique used in habituation was through pilot experiments, followed by teaching experiments. Students respond very positively and are happy to follow it by seeing the very significant development of their abilities during the learning process.
Penelitian ini merupakan penelitian deskriptif kualitatif yang bertujuan untuk mengetahui kemampuan pemecahan masalah matematis siswa setelah pembelajaran dengan menggunakan pendekatan Model Eliciting Activities (MEAS) pada materi Sistem Persamaan Linier Tiga Variabel (SPLTV). Subjek dalam penelitian ini adalah siswa kelas X MIA 6 SMA Negeri 10 Palembang yang berjumlah 5 orang. Penelitian ini menggunakan teknik pengumpulan data berupa tes yaitu tiga soal pemecahan masalah materi SPLTV dan wawancara untuk memperoleh data secara mendalam. Hasil dalam penelitian ini menunjukkan bahwa indikator kemampuan pemecahan masalah yang sering muncul ialah indikator memahami masalah, dimana indikator ini muncul disetiap tingkat kemampuan siswa yaitu tinggi, sedang, dan rendah. Sedangkan indikator yang sangat jarang muncul ialah indikator melihat kembali. Dimana indikator ini hanya muncul pada tingkat kemampuan siswa yang tinggi saja, sedangkan untuk tingkat kemampuan siswa yang sedang dan rendah indikator ini tidak muncul. Penyebab indikator ini jarang muncul karena kebanyakan siswa tidak menghiraukan perintah soal untuk melihat kembali, siswa merasa cukup dengan perolehan hasil akhir tanpa menganalisis kembali hasil yang telah diperoleh.
