Penelitian ini memiliki tujuan untuk mengembangkan LKPD berbasis problem based learning untuk meningkatkan kemampuan pemecahan masalah pada materi barisan dan deret serta untuk mengetahui perbedaan rata-rata hasil belajar peserta didik sebelum dan sesudah diterapkannya LKPD berbasis problem based learning pada materi barisan dan deret. Jenis penelitian yang digunakan yakni penelitian dan pengembangan (Research and Development) dengan menggunakan model pengembangan 4D yang terdiri dari empat tahapan yakni Define, Design, Development, dan Dissemination. Namun, penelitian ini hanya sampai pada tahap Development karena penelitian ini terbatas pada uji laboratorium. Hasil uji kelayakan LKPD yang dikembangkan yakni untuk validasi ahli materi sebesar 93,85% (sangat layak) dan untuk validasi ahli media sebesar 96,67% (sangat layak). Hasil uji paired sample t-test yakni 0.000 < 0.05 yang artinya terdapat perbedaan rata-rata hasil belajar peserta didik sebelum dan sesudah diterapkannya LKPD berbasis problem based learning pada materi barisan dan deret. Dengan demikian, dapat disimpulkan bahwa LKPD yang dikembangkan telah dinyatakan sangat layak dan LKPD yang dikembangkan dapat meningkatkan meningkatkan kemampuan pemecahan masalah peserta didik.

The high perception of difficulty in mathematics stems from its abstract nature, leading to a high rate of student errors. One factor influencing this is individual cognitive style. This study aims to examine students errors in solving probability problems using the Newman procedure from a cognitive style perspective. This study employs a descriptive qualitative approach. Data were collection through the GEFT test, a written probability test, and semi structured interviews. The research subjects consisted of two student from class XII-3 selected through purposive sampling based on following criteria: (1) into the field-independent or field-dependent category, (2) have a good comunication according to the teachers instructions. Data analysis was conducted through the stages of data reduction, data presentation, and conclusion drawing. The findings reveal that students with a field independent cognitive style made errors in transformation, process skills, and encoding. Meanwhile, students with a field dependent cognitive style made errors in comprehension, transformation, process skills, and encoding. These errors were caused by limited mastery of the material, low accuracy, and external influences. The result are expected to assist teachers in designing instructional strategies aligned with students cognitive style to reduce error in problem solving.Keywords: Newman Error Analysis, Probability, Cognitive Style

Mathematical literacy is one of the fundamental skills that students must possess to meet the challenges of the 21st century, particularly in solving contextual problems. This study aims to analyze the mathematical literacy skills of Phase F students in solving AKM questions as viewed through Kolb’s learning styles. This is a descriptive qualitative study conducted in the 11th-grade class at Dr. Soetomo High School in Surabaya. It consisted of four subjects selected using purposive sampling to represent each learning style. Data collection was conducted through the administration of the KLSI 3.1 learning style questionnaire, a mathematical literacy test, and interviews. The research results generally indicate that students with high mathematical literacy skills were able to meet all indicators, such as converging, assimilating, and accommodating learners. Diverging learners (DL) tended to feel bored, resulting in a lack of focus and difficulties in performing calculations. Converging learners (SC) are able to analyze information and apply mathematical concepts systematically. Assimilating learners (SAs) are able to analyze information logically, provide structured answers, and interpret results effectively. Accommodating learners (SAc) are able to analyze information and tend to solve problems based on prior learning experiences. The findings of this study indicate that differences in learning styles influence how students analyze and solve mathematical problems, which can serve as a consideration for teachers in designing instruction.Keyword: Mathematical Literacy, AKM, Kolb Learning Styles

The result of study of student of class VII B in MTs Negeri 1 Kota Surabaya on the subject of wake up flat in academic year 2017/2018 after analyzed have low result, this is allegedly because approach of learning at that time not yet right, hence in this class research used approach of learning Contex Teaching and Learning (CTL), which emphasizes the concept of learning that helps teachers connect between the material they teach and the students' real-world situations and encourages students to make connections between their knowledge and application in daily life. The problem to be discussed is whether the learning of mathematics with CTL approach on the subject of wake up flat can improve student learning outcomes of class VII B in MTs Negeri 1 Kota Surabaya? While the purpose of this research is to find out the improvement of student learning outcomes on the subject of flat wake with CTL approach. The location of the research was conducted at MTs Negeri 1 Kota Surabaya, Medokan Semampir Sub-district, East Java. The subjects of this research are the students of class VII B MTs Negeri 1 Kota Surabaya, teacher of grade VII B SD and observer. The study is divided into 2 cycles, each cycle consisting of planning, implementation, observation and reflection. While the indicator of the success of this class action research is achieved if the students have a grade average of at least 75 and mastery learning classes above 75%. In the first cycle students achieve a grade point average of at least 69.87, while the learning mastery is 47.37%. Cycle II reaches the average grade value of 78.16 and the learning completeness is 60.53%. Based on the results of student learning above can be concluded that learning with CTL approach can improve student learning outcomes of class VII B in MTs Negeri 1 Kota Suarabaya on the subject of algebra, so it is recommended that in teaching on the subject of algebra teachers using CTL approach Keywords: Contex Teaching and Learning (CTL), learning outcomes, operation of algebraic forms
