Abstract

Mathematical literacy skills are very necessary to face and solve various challenges in today's life, so these abilities need to be honed from elementary school. This research aims to analyze whether the increase in the mathematical literacy skills of students taught using a project-based learning model is higher than the mathematical literacy skills of students taught using regular learning. This type of research is quasi-experimental by dividing 2 sample groups as samples that are taught through regular learning and samples taught by applying a project-based learning model. This analysis uses the t-test to compare the means of the two sample groups. The sample in this study was 26 grade 4 children at state elementary school 064967 Medan, North Sumatra. The results of this research were the increase in the mathematical literacy skills of students taught using a project-based learning model was higher than the mathematical literacy abilities of students taught using regular learning. Through project activities, students can provide a rich understanding of concepts and ideas.

Abstract

This study aims to describe students' reflective thinking skills in solving mathematics problems in terms of the learning styles of junior high school students. This type of research was descriptive qualitative research. The research subjects were students of class VIII at SMP Negeri 1 Candimulyo, Magelang Regency, in the academic year 2020/2021. The subjects of this study were 2 visual learning style students, 2 auditory learning style students, and 2 kinesthetic learning style students. Data collection techniques in this study were learning style questionnaires, tests of reflective thinking skills, and in-depth interviews. Triangulation in this study using source triangulation. The results of this study indicate that subjects with visual and auditory learning styles can meet the reflective thinking ability phase (Reacting, Comparing, and Contemplating) with each indicator being met so that the subject was at a reflective level. Kinesthetic learning style subjects were able to meet the reflective thinking ability phase (Reacting, Comparing, and Contemplating) but several indicators were not fulfilled, so the subject was at a fairly reflective level. Therefore, the profiles of students’ reflective thinking skills in visual and auditory learning styles were both at a reflective level, while the profiles of students' reflective thinking skills in kinesthetic learning styles were different because they were at a sufficiently reflective level.

Abstract

Kemampuan numerisasi penting dimiliki siswa agar dapat menyelesaikan permasalahan atau pemecahan masalah dengan baik. Kemampuan numerisasi memberikan kemampuan pada anak berpikir logis dan sistematis dalam mengambil keputusan. Artinya jika seseorang yang memiliki kemampuan numerik maka akan memiliki kemampuan pemecahan masalah yang baik. Tujuan dari penelitian ini adalah menganalisis kemampuan numerisasi dalam menyelesaikan masalah distribusi peluang binomial pada siswa. Metode penelitian menggunakan pendekatan deskriptif kualitatif. Subjek dalam penelitian ini adalah siswa kelas XII yang dipilih berdasarkan gaya belajar yang dimiliki. Teknik pengumpulan data menggunakan tes dan angket penelitian. Teknik analisis data menggunakan deskriptif kualitatif. Hasil penelitian menunjukkan bahwa Siswa dengan gaya belajat visual memiliki kemampuan numerik yang baik dalam hal perhitungan sistematis, berpikir logis, mengkoordinasikan, serat kemampuan mengindeitifikasi pola. Siswa dengan gaya belajar auditorial memiliki kemampuan untuk berpikir logis tetapi masih kurang dalam perhitungan secara matematis. Siswa dengan gaya belajar kinestetik memiliki kemampuan numerik yang baik namun memiliki kelemahan pada kemampuan mengidentifikasi pola-pola yang ada pokok permasalahan.

Abstract

This research aimed to evaluate the effectiveness of Realistic Mathematics Education (RME) to improve students' multi-representation ability. A quasi-experimental design was used in this research. Sixty-four samples from the seventh-grade students of Junior School were randomly selected and divided into two classes: experimental class was treated using RME and control class was treated using conventional learning, with each class consisting of thirty-two students. The essay test was used to measure the multi-representation ability of students and the questionnaire was used to measure students' responses in RME learning. The data from the essay test were analyzed by N-Gain test and t-test in which normality and homogenity test were conducted previously, while the students' learning completeness and student responses were presented descriptive quantitative. The result of the research concluded that the multi-representation ability of students who get RME learning is better than the multi-representation ability in students who get conventional learning. 87.25% of students who get RME learning with the developed device have completed the KKM, and many students are very enthusiastic and interested in RME based learning, thus increasing their learning spirit in a learning process.

Abstract

MGMP Matematika Kabupaten Batang telah berdiri sejak lama namun belum ada kesepakatan terkait pertemuan rutin dan rancangan kegiatan bagi pada anggotanya. Selain itu, para guru di MGMP Matematika Kabupaten Batang belum mengenal STEM-AR yang dapat diaplikasikan dalam pembelajaran matematika. Urgensi dan fokus kegaiatn pengabdian ini adalah memberikan pengetahuan aplikatif yang mengintegrasikan Science, Technology, Engineering, and Mathematics (STEM) dan Augmented Reality (AR) dalam pembelajaran matematika sehingga guru dapat mengembangkan Modul Ajar berbasis Pendidikan STEM-AR dan menerapkannya di kelas matematika. Tujuan dari kegiatan PKM ini adalah membentuk Komunitas Belajar STEM-AR dengan fokus pada bidang sosial kemasyarakatan dan manajemen melalui metode pelaksanaan (1) memberikan pelatihan STEM, AR, dan pembuatan Modul Ajar berbasis Pendidikan STEM-AR, dan (2) penerapan hasil pelatihan dalam mengembangkan Modul Ajar berbasis Pendidikan STEM-AR. Kegiatan PkM Pendidikan STEM-SR bagi Guru Matematika di Kabupaten Batang telah terlaksana hingga pelaksanaan penggunaan teknologi tepat guna. Pada kegiatan pelatihan, Guru SMA di Kabupaten Batang telah memahami dengan baik terkait pendidikan STEM, AR, dan pengembangan modul ajar berbasis STEM-AR. Sudah 100% guru matematika di Kabupaten Batang telah mampu mengembangkan modul ajar berbasis STEM-AR. Guru Matematika Kabupaten Batang juga telah menerapkan pembelajaran berbasis STEM di kelas matematika, namun memang masih perlu ditingkatkan agar pembelajaran dapat berjalan lebih efektif. Siswa dalam kelas tampak antusias dengan pembelajaran berbasis STEM ini karena merupakan pengalaman baru bagi mereka. Perlu adanya perbaikan berkelanjutan dalam proses pembelajaran sehingga kelas menjadi lebih efektif.

Abstract

Soft skills are essential factors in preparing students to face the increasingly competitive job market. However, traditional learning methods often pay less attention to the development of these non-technical skills. This study aims to analyze the impact of project-based learning integrated with STEAM (Science, Technology, Engineering, Arts, and Mathematics) on improving students' soft skills in the Organic Chemistry course, particularly in the topic of hydrocarbons. The research employs a quantitative approach with a descriptive-correlational design. The sample was selected purposively, involving 33 students who took the Organic Chemistry. Data were collected through a closed-ended questionnaire using Google Form, and the data analysis was conducted using simple linear regression. The results showed that the project-based learning method integrated with STEAM (PJBL-STEAM) had a significant impact on the development of students' soft skills, with a determination coefficient (R²) value of 0.300. This indicates that the method explains 30% of the variation in soft skills improvement, while the remaining percentage is influenced by other factors beyond this study. In conclusion, this study highlights that PJBL-STEAM is not only effective in enhancing students' technical abilities but also plays a crucial role in developing the non-technical skills required in professional settings.
