Abstract

Kemampuan penalaran memiliki peran penting dalam tercapainya tujuan pembelajaran, namun danya siswa yang kurang memahami dan menggunakan nalar dengan baik menyebabkan siswa gagal menguasai pokok bahasan. Penelitian ini bertujuan untuk mendeskripsikan kemampuan penalaran matematis siswa berbasis masalah dalam meneyelesaikan permasalahan pada materi bilangan pecahan. Metode yang digunakan dalam penelitian ini adalah deskriptif kualitatif. Instrumennya berupa hasil studi dokumentasi yaitu LKS dengan soal kemampuan penalaran matematis pada saat pembelajaran matematika dan wawancara. Penelitian dilakukan di SMP Negeri 7 Kota Bengkulu. Hasil penelitian menunjukkan bahwa secara keseluruhan siswa dapat menyelesaikan soal permasalahan kemampuan penalaran dengan kategori sedang, masih terdapat beberapa permasalahan yang mereka lewatkan sehingga jawaban yang dihasilkan kurang tepat.

Abstract

Numeracy literacy skills are basic competencies that need to be developed in junior high school (SMP) students in the 21st century. However, mathematics learning in schools has not yet linked the concept of mathematics to the cultural context in daily life. This research aims to develop Student Worksheets (LKPD) in the Context of Tabut Culture with a valid and practical STEAM approach to facilitate students' numeracy literacy. This research uses the Research and Development (R&D) method with a 4D development model comprising define, design, and develop stages, while the disseminate stage is not carried out. The research subjects included 31 students and 1 mathematics teacher in grade VII of SMPN 1 Kepahiang. The research instrument consists of validation sheets and questionnaires on the practicality of students and teachers. The study's results showed that the LKPD developed had a validity rate of 87.83% in the very valid category. The results of the practicality test showed that 80.67% of students were in the practical category, and 82.27% of teachers were in the very practical category. These findings show that LKPD, in the context of Ark Culture with a STEAM approach, is suitable as innovative teaching materials to support contextual mathematics learning and improve students' numeracy literacy.

Abstract

This community service activity aims to improve teachers' capacity in writing scientific articles as part of ongoing professional development. A total of 30 teachers from the Avicena Bengkulu Learning Community participated in a webinar titled "Writing Scientific Articles for Teachers," held online on September 25, 2024, via Google Meet. The activity consisted of delivering materials and facilitating interactive discussions on the structure of scientific articles, adjustments to journal templates, and publication strategies. The activity results showed high enthusiasm among participants, reflected in their active questioning and readiness to prepare the initial draft of the article. This activity increased participants' understanding of the importance of scientific publications and encouraged them to begin writing based on the learning practices they had undertaken. This webinar is a genuine contribution from lecturers to strengthening publication literacy among teachers as part of improving professionalism.

Abstract

Mathematical critical thinking ability is the capacity to investigate, discover, connect, and assess every aspect of a problem carefully and thoughtfully to arrive at the best solution. This study aims to describe students' mathematical critical thinking abilities regarding circles in Grade VIII at SMP Negeri 09 Lebong. This research is a qualitative descriptive study with 20 student participants. Three students were interviewed: one with high ability, one with medium ability, and one with low ability. Data collection methods included tests, interviews, and documentation. The research instruments consisted of test items and interview guidelines. The data analysis technique involved data collection, data reduction, data presentation, and conclusion. The results of the study show that high-ability students met all indicators of mathematical critical thinking: Interpretation, Analysis, Evaluation, and Conclusion. Medium-ability students met two indicators: Interpretation and Analysis. Low-ability students were unable to meet the indicators of mathematical critical thinking: Interpretation, Analysis, Evaluation, and Conclusion.

Abstract

The purpose of this study is to investigate how the understanding of mathematical concepts by grade XI students at SMA N 6 Bengkulu City is influenced by the application of the mind mapping method. This study employs a quasi-experimental design with control groups. The participants consist of two sections, each with thirty-six students: XI MIPA A and XI MIPA D. The use of mind mapping techniques serves as the independent variable, while students' conceptual knowledge is the dependent variable. Measurements were conducted using tests. Data analysis compared the conceptual knowledge of the experimental and control groups using t-tests and hypothesis tests with a significance level of 5%. The findings indicate that mind mapping positively affects the students' conceptual understanding of mathematical matrices. The conceptual understanding of the experimental group improved significantly, as evidenced by the posttest results, compared to the control group that utilized conventional methods. In conclusion, the mind mapping learning model proves to be an effective tool in enhancing students' comprehension of mathematical concepts.
