Abstract

Tujuan penelitian adalah menganalisis proses berpikir peserta didik menurut de Bono dalam memecahkan masalah matematik ditinjau dari dominasi otak. Penelitian ini menggunakan metode kualitatif deskriptif. Subjek penelitian berasal dari tiga kelompok yaitu peserta didik berdominasi otak kiri, kanan dan seimbang. Teknik analisis data meliputi reduksi data, penyajian data, dan penarikan kesimpulan. Hasil penelitian menunjukkan bahwa peserta didik berdominasi otak kiri memiliki proses berpikir vertikal, berdominasi otak kanan memiliki proses berpikir lateral, dan berdominasi otak seimbang memiliki proses berpikir vertikal juga berpikir lateral. Namun terdapat perbedaan berpikir vertikal antara peserta didik berdominasi otak seimbang dengan yang berdominasi otak kiri, yaitu peserta didik berdominasi otak seimbang dalam memahami masalah dan menyusun rencana penyelesaian melalui membaca holistik dengan pendekatan intuitif, sedangkan peserta didik berdominasi otak kiri melalui membaca fonetik, rasional dan detail. Perbedaan juga terdapat antara berpikir lateral peserta didik berdominasi otak seimbang dengan peserta didik berdominasi otak kanan, yaitu peserta didik berdominasi otak seimbang dalam menyelesaikan masalah dengan cara analitis dan menunjukkan respon verbal, sedangkan peserta didik dominasi otak kanan tidak menunjukkan proses penyelesaian yang analitis (sintetis) dan menunjukkan respon non verbal.

Abstract

Certification of teachers that has lasted more than a decade aimed to produce professional teachers, thus impacting significantly to the advancement of education in Indonesia. But the reality in Tasikmalaya, West Java, it is very much different from the expectations. The majority of teachers are even more concerned about the increase of social status than the professional quality as an educator. More recently the government has implemented Teacher Competency Test (UKG), which was held simultaneously throughout Indonesia with the aim to determine the ability of teachers’ pedagogical and professional competencies. The purpose of this study was to determine the mapping of the teachers’ competency by rank, domain competence, academic qualification, age, gender, and see the difference in results UKG based certification status. Outputs resulting from this study were (1) to map the results UKG mathematics of junior high school in Tasikmalaya, (2) to formulate recommendations or proposals regarding the improvement of the UKG (3) to formulate recommendations or proposals of the sustainable planning of professional development for teachers. The method used in this research were studied documentation, interviews and questionnaires open. The mapping of UKG results can be used as consideration in evaluating the program especially in what improvements need to be prioritised. By using the techniques of interviews and open questionnaire, was expected collect information of the effect of UKG for the teachers.

Abstract

Matematika adalah ilmu tentang pola, struktur, dan representasi benda yang tumbuh dan berakar pada kehidupan nyata. Pola, struktur, dan bentuk benda-benda tersebut dapat ditemukan dalam kehidupan sehari-hari dan penerapan konsep matematika yang terintegrasi dalam adat budaya yang disebut etnomathematika. Salah satu konsep matematika tersebut terdapat pada ukiran Jepara. Penelitian ini menggunakan metode deskriptif-kualitatif untuk mendeskripsikan filosofi seni pahat Jepara, unsur-unsur matematika dalam seni pahat Jepara, dan keterkaitan antara kedua fokus studi tersebut. Pengumpulan data menggunakan wawancara, observasi, dan dokumentasi. Subjek penelitian adalah pengrajin ukiran Jepara. Hasil penelitian menunjukkan bahwa: (1) Seni ukir Jepara kaya akan filosofi, meliputi nilai, ajaran, dan kepercayaan yang berkaitan dengan agama, akhlak, dan budaya yang melatarbelakangi ukiran Jepara, (2) unsur matematika terintegrasi dalam pola pikir pengrajin dan diterapkan dalam pembuatan ukiran Jepara, termasuk kegiatan matematika yang berkaitan dengan berhitung, mencari lokasi, mengukur, dan merancang, serta konsep matematika yang berkaitan dengan titik, garis, sudut, gradien, geometri datar, lingkaran, bentuk geometris, kekosongan, dan transformasi geometri refleksi. dan rotasi, (3) filosofi dan unsur matematika secara bersama-sama berperan penting dan mendukung keberadaan seni ukir Jepara menjadi seni yang kaya nilai.

Abstract

This study aims to determine the role of the amoeba breeding context and to produce students' learning trajectories in learning rank numbers through a guided inquiry learning model using Google Jamboard. This research method uses Design Research (DR), which includes 3 stages: preliminary design), experimental design, and retrospective analysis. The research begins with a literature review and designing the HLT. The learning design was prepared based on the HLT which was then tested through 2 stages, namely the pilot experiment and teaching experiment. A retrospective analysis was performed at each stage by comparing the initial HLT with the actual learning trajectory. The data collection techniques used were observation, recording of learning activities during experimental design, giving LKPD, giving evaluation questions, and interviews. This research was conducted on students of SMP Negeri 5 Tasikmalaya class IX-B at the pilot experiment and IX-A at the teaching experiment. The results of this study indicate that the role of the Amoeba breeding context can help facilitate students to build basic concepts in finding the concept of exponent number material. In addition, a learning trajectory is produced that can help students understand the concept of rank number material, with the context of Amoeba breeding through guided inquiry using Google Jamboard.

Abstract

This research aims to develop an effective learning design for understanding the concept of exponentiation by applying the Discovery Learning model using the Hypothetical Learning Trajectory (HLT) as the framework foundation. The research method used is a design research method consisting of three main stages: preliminary design, teaching experiment, and retrospective analysis. The initial stage involves literature analysis and the design of an HLT tailored to the concept of exponentiation. The instructional design is based on the prepared HLT and tested through two experimental stages: pilot experiment and teaching experiment. Retrospective analysis is conducted to compare the initial HLT with the Actual Learning Trajectory (ALT) achieved during the learning process. Data is collected through observation to monitor learning activities and environmental conditions, as well as through recordings of learning activities to gain an understanding of student participation in the design experiments. Additionally, Student Worksheets (SW) are used as aids for students to understand the concept of exponentiation, and evaluation questions are used to measure students' learning outcomes in the subject matter. Interviews are also conducted to gain a deeper understanding from the student's perspective. The results of this research make a significant contribution to the development of more effective mathematics learning methods, particularly in understanding the concept of exponentiation, and provide guidance for teachers to design learning that is more relevant to students' daily lives. The implications of the research results provide guidelines for teachers in designing learning that is more relevant to students' daily lives.

Abstract

Jepara's carving is a work of art with a mathematical concept of aesthetic value. Mathematical aesthetics refers to the relationship between mathematics and aesthetic values, namely the beauty of mathematics integrated with the art of Jepara's carving. The qualitative descriptive method is used to describe aesthetics and mathematical concepts in Jepara's carving and the relationship between the two focuses of the study. Data were collected using semi-structured interviews, non-participatory observation, and documentation. The research subjects consisted of two informants: art and culture teachers and Jepara's carving artisans. The data were analyzed using the Miles and Huberman model, which consisted of the following stages: data reduction, data presentation, and conclusion drawing. The results showed that: (1) Jepara's carving has aesthetic value, seen from the fulfillment of aesthetic elements, namely: unity, complexity, sincerity, and balance; (2) the process of making Jepara's carving applies the mathematical concept of comparison, which plays an essential role in making Jepara's carving patterns; and (3) there is a collaboration between the application of mathematical concepts and aesthetic theory in creating the term mathematical aesthetics in Jepara's carving which refers to geometric aesthetics, wherein this Jepara's carving motif there is a regularity of patterns dominated by   .
