This research aims to produce a valid and practical e-module using the Bengkulu context that potentially affects students' literacy skills to understand the materials of patterns and number sequences. This research employed a research and development method. The development stages refer to Plomp’s five developments: (1) preliminary research, (2) the prototype-making stage, and (3) the assessment stage. The subjects of this research were 24 eighth-graders of SMP Negeri 6 Bengkulu City. The data collection techniques of this research were observation and test. Meanwhile, the research instruments were validation instruments, questionnaires, and literacy test questions. Validity analysis was conducted descriptively and consisted of an analysis of validity, practicality, and literacy test results. The average score of the expert validity is 0.64 and meets the valid criterion. The e-module has a practical category with a score of 3.55, and the requirements are very practical. The e-module has impacted students' literacy skills with an average score of 74.25 or good criteria. Moreover, e-module using Bengkulu context problems can encourage students to improve their mathematical literacy skills.

The observation results showed that practicum activities and student learning outcomes in algebra courses were not optimal. Therefore, a learning model is needed that can make students carry out practical activities directly in class and can improve student learning outcomes This study aimed to determine the increase in student learning outcomes through the use of Rational Function Student Worksheets based on the GeoGebra-assisted APOS model. The type of research carried out is Classroom Action Research (CAR). The research instrument was in the form of a learning achievement test sheet. The subjects of this study were first semester students of the Mathematics Education Study Program at Bengkulu University in 2022. The results showed that the average learning outcomes were 71.26 in cycle I and 82.05 in cycle II with a percentage of completeness in student learning outcomes of 82.05%. in cycle II. So it can be concluded that learning using rational function student worksheets based on the APOS model assisted by GeoGebra can improve student learning outcomes.Hasil observasi menunjukkan bahwa kegiatan praktikum dan hasil belajar mahasiswa pada mata kuliah aljabar belum optimal. Oleh karena itu, diperlukan model pembelajaran yang dapat membuat mahasiswa melakukan kegiatan praktikum secara langsung dikelas dan dapat meningkatkan hasil belajar mahasiswa. Penelitian ini bertujuan untuk mengetahui peningkatan hasil belajar mahasiswa melalui penggunaan Lembar Kerja Mahasiswa fungsi rasional berbasis model APOS berbantuan GeoGebra. Jenis penelitian yang dilaksanakan adalah Penelitian Tindakan Kelas (PTK). Instrumen penelitian berupa lembar tes hasil belajar. Subjek penelitian ini yaitu mahasiswa semester I Program Studi Pendidikan Matematika Universitas Bengkulu Tahun 2022. Hasil penelitian menunjukan bahwa rata-rata hasil belajar yaitu 71,26 pada siklus I dan 82,05 pada siklus II dengan persentase ketuntasan hasil belajar mahasiswa sebesar 82,05% pada siklus II. Sehingga dapat disimpulkan bahwa pembelajaran menggunakan lembar aktivitas mahasiswa fungsi rasional berbasis model APOS berbantuan GeoGebra dapat meningkatkan hasil belajar mahasiswa.

One of the problems that often occur in learning mathematics at school is the difficulty of teachers in providing test instruments. This research aims to develop a valid and practicaly high-level thinking mathematics test instrument for senior high school students in the local context. The higher-order thinking levels that are the focus of this research are analysis, evaluation, and creativity. The type of research conducted is development research using a formative evaluation design. The research instrument consisted of validity sheets and practicality sheets. The validity of the test instrument was analyzed using the Aiken index. The practicality test was carried out in a small group tryout with the subject of the tenth grade of Senior High School in Bengkulu. The study results were high-level thinking math questions in the local context for the tenth grade that were valid and practical, consisting of 5 multiple choice questions with 2 levels of analysis, 2 questions for evaluation, 1 creative question, and 3 essay questions covering all three levels.

Tujuan dari penelitian ini adalah untuk mengembangkan instrumen tes matematika berpikir tingkat tinggi untuk siswa SMA dalam konteks lokal yang valid dan praktis. Level berpikir tingkat tinggi yang menjadi fokus dalam penelitian ini adalah: analisis, evaluasi, dan kreatif. Jenis penelitian yang dilakukan adalah penelitian pengembangan menggunakan desain formatif evaluation. Instrumen penelitian terdiri dari lembar validitas dan lembar kepraktisan. Validitas instrumen tes dianalisis menggunakan indeks Aiken. Uji kepraktisan dilakukan dalam uji coba kelompok kecil dengan subjek kelas X SMA di Bengkulu. Hasil penelitian berupa soal matematika berpikir tingkat tinggi untuk siswa kelas X SMA konteks lokal yang valid dan praktis sebanyak 5 soal pilihan ganda dengan level analisis sebanyak 2 soal, evaluasi sebanyak 2 pertanyaan, dan kreatif sebanyak 1 pertanyaan serta 3 soal uraian yang mencangkup ketiga level. Soal memenuhi kriteria valid berdasarkan penilaian penguji dan praktis ditinjau dari keterbacaan pada uji kelompok kecil. Hasil uji coba terhadap 24 siswa menunjukkan bahwa sebanyak 14 siswa berada pada kategori sedang (58,33%), 7 siswa pada kategori baik (29,17%), dan 3 siswa pada kategori tinggi (12,50%).
