Logical thinking is the process of drawing conclusions based on facts through systematic steps and relevant arguments. This ability can be developed through mathematics learning, especially in problem-solving. This study aims to describe the logical thinking profile of junior high school students in solving AKM numeracy problems in algebra content.The research employs a descriptive method with a qualitative approach. The research instruments consist of two AKM numeracy problems related to systems of linear equations in two variables (SPLDV) and number patterns, as well as a validated semi-structured interview guide. Data were collected through a logical thinking test and interviews to identify indicators of logical thinking, namely coherence in reasoning, argumentation ability, and conclusion drawing. The test was administered to 30 eighth-grade students from SMP Negeri 1 Genteng. The results showed that two students met all indicators of logical thinking. These students were able to understand the problem by clearly writing down important information using their own words. They planned their solutions logically, applying the elimination and substitution methods for SPLDV problems and identifying number patterns in different ways. Their problem-solving steps aligned with Polya’s stages: understanding the problem, planning, implementing, and reviewing. Both students wrote conclusions supported by logical reasoning.

Representasi matematis menjadi salah satu aspek penting dalam belajar matematika karena dengan kemampuan representasi matematis yang baik, dapat membantu memecahan permasalahan kompleks menjadi lebih sederhana. Penelitian ini merupakan penelitian deskriptif kualitatif yang bertujuan untuk mendeskripsikan kemampuan representasi matematis siswa Field Dependent (FD) dan Field Independent (FI) dalam menyelesaikan dua soal uraian persamaan garis. Subjek dalam penelitian ini adalah siswa kelas VIII-I SMP Negeri 1 Jember tahun ajaran 2019/2020 yang terdiri dari 10 siswa FD dan 19 siswa FI. Hasil penelitian menunjukkan bahwa dalam menyelesaiakan masalah, FD cenderung menggunakan dua indikator representasi matematis yaitu ekspresi matematis dan verbal. FD belum mampu memahami informasi yang diberikan pada soal dengan tepat sehingga, rencana penyelesaian yang dibuat tidak mengarah pada solusi. FI sudah mencakup tiga indikator representasi matematis yaitu visual berupa sketsa grafik titik potong sumbu-X dan sumbu-Y dengan tepat dan tabel untuk memperjelas masalah, ekspresi matematis berupa model matematika yang digunakan juga ditulis dengan runtut dan tepat serta representasi verbal yang digunakan berupa kesimpulan dan penjelasan langkah-langkah penyelesaian dari tes tulis juga dapat dijawab dengan baik menggunakan bahasanya sendiri. Selain itu, FI juga dapat menyelesaikan soal menggunakan alternatif penyelesaian lain.

Students often feel reluctant to work on worksheets given by teachers because of their unattractive appearance, monotony, and only consisting of material or a collection of questions that do not guide students to find the concept of the material. This makes learning boring and meaningless. Therefore, a development research was conducted on student worksheets using a blended learning model of the flipped classroom type on the material of the system of two linear equations in grade VIII. The purpose of this research is to determine the process and results of developing student worksheets using a blended learning model of the flipped classroom type on the material of the system of two linear equations in grade VIII. The design of the student worksheet in this research is based on the 4-D development model which consists of 4 stages, namely the defining stage (define), design (design), development (develop), and dissemination (disseminate). The development results show that the student worksheets are valid with an average total validity of 3.96; practical with a percentage of learning implementation of 97.06% stated as good; and effective with a percentage of student activity of 90.38% stated as very active, student response questionnaire of 96.08% stated as positive, and a percentage of student mastery of 86.96% stated as classically complete. ABSTRAKSiswa kerap kali enggan mengerjakan lembar kerja siswa yang diberikan oleh guru karena tampilannya yang tidak menarik, monoton, dan hanya terdiri atas materi atau kumpulan soal yang tidak menuntun siswa untuk menemukan konsep materi. Hal tersebut membuat pembelajaran menjadi membosankan dan kurang bermakna. Oleh karena itu, dilakukan penelitian pengembangan lembar kerja siswa menggunakan model blended learning tipe flipped classroom pada materi sistem persamaan linier dua variabel kelas VIII. Adapun tujuan penelitian ini untuk mengetahui proses dan hasil pengembangan lembar kerja siswa dengan model blended learning tipe flipped classroom pada materi sistem persamaan linier dua variabel kelas VIII. Rancangan lembar kerja siswa pada penelitian ini berdasarkan model pengembangan 4-D yang terdiri dari 4 tahap yaitu tahap pendefinisian (define), perancangan (design), pengembangan (develop), dan penyebaran (disseminate). Hasil pengembangan menunjukkan lembar kerja siswa valid dengan rata-rata total validitas 3,96; praktis dengan presentase keterlaksanaan pembelajaran 97,06% dinyatakan baik; dan efektif dengan presentase keaktivan siswa 90,38% dinyatakan sangat aktif, angket respon siswa 96,08% dinyatakan positif, dan presentase ketuntasan siswa 86,96% dinyatakan tuntas secara klasikal.

Errors in constructing concepts often occur in mathematics learning, especially in the topic of integer operations. These errors arise because students tend to memorize procedures or rules without fully understanding the underlying concepts. This research aims to analyze students' errors in constructing the concept of integer operations based on assimilation and accommodation. This study uses a qualitative method with 16 students from class VII B at MTs Baitul Hikmah Tempurejo as subjects. The data collection methods in this study included tests and interviews. Data analysis was carried out through the stages of analyzing test results, conducting interviews, and triangulating the data to ensure validity. Based on the analysis and discussion of the data, it can be concluded that all subjects experienced errors in constructing the concept. Four types of concept construction errors were identified: Pseudo Construction, Construction Hole, Mis-logical Construction, and Mis-analogical Construction. Pseudo Construction occurs when a student merely memorizes phrases like "negative meets negative, the result is positive" without a deeper understanding of the concept. Construction Hole occurs when a student provides incorrect answers due to incomplete understanding or failure to comprehend the problem. Mis-logical Construction happens when a student makes an incorrect assumption or conclusion, while Mis-analogical Construction involves false analogies, such as equating the concept of adding negative numbers with adding positive numbers. The results of this study are expected to provide insights into the types and causes of errors in concept construction made by students, which can then be used as a basis for developing effective learning strategies to help students understand concepts correctly.
