Abstract

Modul yang digunakan guru pada pembelajaran matematika di SMKN 8 Malang lebih menekankan pada materi, contoh soal dan latihan soal. Contoh soal yang diberikan sudah berbasis kontekstual, tetapi kurang memberi kesempatan siswa untuk terlibat dalam pembelajaran. Hampir seluruh siswa dari tahun ketahun memperoleh hasil ujian dibawah KKM (kurang dari 60) pada materi barisan dan deret, karena kurangnya pemahaman siswa terhadap materi. Berdasarkan hal tersebut, peneliti bertujuan untuk mengembangkan Lembar Kegiatan Siswa (LKS) beracuan Problem Based Learning (PBL) untuk mendeskripsikan kemampuan penalaran matematika siswa SMKN 8 Malang pada materi barisan dan deret aritmetika yang memenuhi kriteria valid, praktis dan efektif. Prosedur penelitian mengacu pada model ADDIE. Penelitian ini dianalisis dengan menguji kevalidan, kepraktisan, dan keefektifan. Uji kevalidan LKS dilakukan oleh 2 validator, yaitu dosen matematika sebagai validator ahli dan guru SMKN 8 Malang sebagai validator praktisi. Setelah LKS dinyatakan valid, LKS diujicobakan kepada siswa kelas XI RPL C tahun ajaran 2021/2022 yang berjumlah 33 siswa. Berdasarkan hasil analisis data, diperoleh tingkat validitas LKS yang dihasilkan dikategorikan valid dengan skor rata-rata 3.39. Rata-rata skor hasil uji kepraktisan mencapai yang berarti dalam kategori praktis. Tingkat keefektifan LKS beracuan PBL yang dihasilkan dikategorikan efektif. Hal tersebut diperoleh dari hasil tes formatif dan pada saat wawancara. Hasil tes formatif dan wawancara menunjukkan bahwa siswa dapat mencari struktur atau pola dari suatu permasalahan, siswa dapat memilih serta menggunakan prosedur dan konsep untuk menyelesaikan masalah, siswa dapat menghubungkan konsep antar matematika atau matematika dengan bidang lain, siswa dapat memeriksa dan menjelaskan solusi dari permasalahan.

Abstract

This research aims to analyze the result of students' work in finding the solution to math-problems about absolute functions. Commognitive's analysis was used to analyze student works in this qualitative research. This research's methods were, namely, preparing, collecting data, transcription data, and analyzing data. A total of 25 students from two universities were given math questions, and two were selected as research subjects. The selection of subjects is based on different and exciting work results. The research subjects attended in-depth interviews to learn more about the commognitive's components. The results showed that commognitive conflict occurred in the word use component when the subject experienced errors in interpreting the data on the questions. Subjects cannot correctly describe the graphic requested in the questions (visual mediators). Describing what is known in the problem is also incompatible (narratives). Subjects experienced the incorrect routines. Based on the results of in-depth interviews, it can be said that the commognitive conflicts occurred because of a lack of understanding of the concepts.

Abstract

This study aims to analyze the order of textbooks based on van Hiele's theory. The research approach used is descriptive qualitative. The method used is content analysis or content study. The data subject in this research is junior high school mathematics textbook grade VIII curriculum 2013. The research was conducted by looking at the suitability of the characteristics at each van Hiele level with the textbook. Then if a discrepancy is found in the analysis, a solution is given according tZo the researcher's skills. The results showed that in general all the material "Surface Area of Cuboid and Cubes" in the Mathematics textbook of junior high school grade VIII curriculum 2013 material on the concept of surface area of cuboid and cubes has not fulfilled the order based on van Hiele's theory as a whole, namely there is an incomplete explanation in each level. The level of sequence analyzed in this textbook reaches level 2 (Ordering). So it is recommended for future research that the results of this analysis be used as a reference in teaching geometry material to students.

Abstract

Penelitian ini bertujuan untuk meningkatkan hasil belajar dan keaktifan siswa di SDN Bareng 1, Kabupaten Malang. Penelitian ini merupakan penelitian tindakan kelas (PTK) yang dilakukan dalam tiga siklus. Subjek penelitian mencakup seluruh siswa dan guru yang terlibat dalam pembelajaran, serta kepala sekolah yang memberikan masukan melalui wawancara. Kegiatan praktik pembelajaran terbimbing dilakukan oleh mahasiswa praktikan dengan subjek siswa kelas 3A. Hasil penelitian menunjukkan bahwa keaktifan belajar siswa meningkat, yang berdampak pada peningkatan hasil belajar dari siklus I hingga siklus II. Peningkatan ini terjadi karena penerapan model Project-Based Learning (PBL), di mana siswa mengerjakan lembar kerja, menyusun, dan menyelesaikan tugas proyek secara berkelompok. Melalui PBL, siswa lebih aktif berdiskusi, berkolaborasi, dan bertanggung jawab terhadap tugasnya. Hasil penelitian ini membuktikan bahwa penerapan model PBL dapat meningkatkan keaktifan dan hasil belajar siswa secara signifikan. Dengan mendorong keterlibatan siswa dalam proses pembelajaran, PjBL menciptakan lingkungan belajar yang lebih dinamis dan bermakna. Oleh karena itu, model ini direkomendasikan sebagai strategi pembelajaran untuk meningkatkan partisipasi dan pencapaian akademik siswa di sekolah dasar.

Abstract

The urgency of this research is to see the tendency for non-generative thinking in students to solve rectangular problems, which defined as a degenerative thinking disposition. A degenerative thinking disposition is a person's tendency to take action that ignores information excessively without considering analytical and genetic characteristics in generalizing a problem. The results of the preliminary study show that there are indications of non-generative thinking when students solve problems regarding the perimeter of a rectangle. Many students point out the incompleteness of the solution to the problem of the perimeter of a quadrilateral and tend to be hasty in assuming that the quadrilateral in question is a rectangle. This included in the symptoms that do not give rise to relational aspects. This type of research is qualitative with an exploratory, descriptive approach to three subjects. The data analysis technique uses thematic analysis steps. The results of the study show that students who experience degenerative thinking dispositions from non-relationship aspects ignore information excessively. Students with non-relationship aspects tend to experience excessive information neglect when relating information to definitions and analytical and genetic properties. Students overgeneralize the problem of rectangular properties without considering the existence of other esufficient elements. The concepts used in concluding problem solutions are based on still partial concepts. So the generalizations that are used as the basis for solving other problems end up being wrong.

Abstract

The current study attempted to describe pre-service teachers’ symbolic-visual representation skills in adding and subtracting fractions. It specifically aimed to analyze the teachers’ ability to construct either a symbolic or visual representation in fraction operations. A case study was conducted by involving 17 fifth-semester students who were enrolled in a teacher training course at one of universities in Ternate, Indonesia. The participants consisted of two males and fifteen females. The study data were gathered using a fraction problem-solving test. The results showed that: 1) the majority of participants succeeded in performing fraction operations and making representations by adding and subtracting fractions; 2) the participants demonstrated proficiency in executing fraction operations but showed poor ability in generating different representations of fractions; 3) the participants were more successful in creating visual representation for fraction addition compared to fraction subtraction. The participants also excelled in constructing circle models as visual representations, outperforming other visual representation models such as number lines, rectangular models for transition situations, and numerical representations of mixed fractions.
