Abstract

Cramer's rule is used by combining matrix determinant methods applied in the presentation of solving Systems of Linear Equations (SLE). The purpose of this study was to determine the differences in student learning outcomes when using the Cramer Rule assisted by the Sarrus Method using the elimination substitution method on two-loop electrical circuit material. The research method used is the Posttest-Only Control Design experimental method.  The results of this study are evidenced by the results of the hypothesis test which states that there is a significant difference between the learning outcomes of the control class and the learning outcomes of the experimental class. As well as the results of a very positive response from students to the implementation of Cramer's rule assisted by the Sarrus method. Thus, the conclusion of this study is that the implementation of Cramer's rule assisted by Sarrus method is proven to be effective as an alternative solution to solving two-loop electrical circuit problems.

Abstract

Science learning provides an opportunity to prepare students with 21st-century Engineering Design Thinking skills (EDT). EDT is a means of looking at and addressing daily real-world problems that greatly need solutions. This study aims to explore students’ EDT skills on alternative energy issues, specifically problem identification and developing ideas and plans. This research is a qualitative exploratory study in a senior high school in the Jember district. The learning design in this study uses the Science Learning through Engineering Design (SLED) models. Research data was gathered through observation and students’ worksheet documents. Content analysis is used as an approach to analyzing data. The results indicated that EDT trains students’ thinking processes to become more critical through problem identification and creativity in developing new ideas and imagination. EDT provides opportunities for students to combine their creativity and critical thinking to produce innovative design solutions. It improves students' epistemic comprehension while studying and helps them acquire relevant knowledge. This research is expected to be supplementary information for teachers to integrate EDT into their learning so that students can achieve meaningfulness and epistemic understanding.

Abstract

Viskositas merupakan kekentalan suatu fluida atau zat cair yang diakibatkan adanya gaya gesekan antar molekul yang menyusun fluida. Tujuan dari penelitian ini yaitu untuk menganalisis kecepatan jatuh benda terhadap viskositas. Metode yang digunakan adalah metode eksperimen sederhana serta menggunakan teknik pengukuran manual yang tidak terlalu rumit. Berdasarkan penelitian yang dilakukan menghasilkan data yaitu pada air jernih kecepatan benda jatuh 0,242 m/s dan nilai viskositas sebesar 0,544 N.m/s2. Pada air keruh kecepatan benda jatuh 0,186 m/s dan nilai viskositas sebesar 0,708 N.m/s2. Pada minyak baru kecepatan benda jatuh 0,134 m/s dan nilai viskositas sebesar 0,984 N.m/s2. Sedangkan pada minyak curah kecepatan benda jatuh 0,197 m/s dan nilai viskositas sebesar 0,669 N.m/s2. Pada oli baru kecepatan benda jatuh 0,138 m/s dan nilai viskositas sebesar 0,955 N.m/s2. Dan pada oli bekas kecepatan benda jatuh 0,212 m/s dan nilai viskositas sebesar 0,622 N.m/s2. Sehingga diperoleh hubungan kecepatan dengan nilai viskositas adalah berbanding terbalik.

Abstract

Tujuan penelitian ini adalah memanfaatkan laboratorium virtual Physic Education and Technology (PhET) simulation sebagai media pembelajaran sebagai salah satu solusi inovatif yang dapat dilakukan dalam upaya  meningkatkan pemahaman konsep fisika mahasiswa. PhET menyediakan simulasi virtual interaktif yang dapat digunakan secara daring maupun luring, sehingga cocok untuk lingkungan dengan keterbatasan akses internet dan juga keterbatasan infrastruktur seperti fasilitas laboratorium. Jenis penelitian ini merupakan penelitian kuantitatif. Penelitian ini dilakukan dengan metode eksperimen berbentuk one group pretest-posttest design. Sampel penelitian yaitu mahasiswa Program studi Pendidikan IPA Tahun Ajaran 2024/2025  sebanyak 14 orang. Pengambilan data dilakukan dua kali yaitu sebelum melakukan treatment (pretest) dan sesudah melakukan treatment (posttest), kemudian untuk mengetahui peningkatan pemahaman konsep fisika mahasiswa dilakukan uji N-gain. Hasil analisis data menunjukkan bahwa peningkatan hasil belajar mahasiswa memperoleh kriteria tinggi dengan skor N-gain sebesar 0,732. Oleh karena itu hasil studi menyatakan bahwa penggunaan laboratorium virtual PhET simulation sebagai media pembelajaran dapat meningkatkan kemampuan pemahaman konsep fisika mahasiswa.

Abstract

Abstrak Masalah yang dihadapi para guru ini adalah merancang pembelajaran yang mampu memenuhi kebutuhan karakterisik belajar siswa yang beragam, baik yang regular maupun anak berkebutuhan khusus. Salah satu strategi yang bisa dilakukan untuk mengupayakan hal tersebut di era Merdeka Belajar ini adalah dengan Pembelajaran Differensiasi. Pelaksanaan pembelajaran berdiferesnsiasi melibatkan unsur yang menjadi fokus pembelajaran abad 21. Tujuan kegiatan pelatihan ini untuk meningkatkan pengetahuan mengenai pembelajaran berdiferensiasi sehingga kualitas pembelajaran sesuai tuntutan abad 21 dapat terpenuhi dalam era merdeka belajar ini. Metode pelaksanaan meliputi pemberian materi oleh narasumber, diskusi serta tanya jawab antara peserta dengan narasumber, pendampingan, dan evaluasi. Pelatihan dilakukan pada 9 guru SMP Negeri 4 Sukowono pada Mei , Juni dan Juli 2024. Pada akhir pelatihan, peserta melakukan posttest  dan mengisi survei melalui angket respon yang hasilnya diukur menggunakan Skala Likert, dan diperoleh nilai rata-rata 80 dan skor 87% untuk komponen pengetahuan peserta. Berdasarkan data yang diperoleh dari isian posttest dan angket respon menunjukkan bahwa terjadi peningkatan pengetahuan peserta pelatihan mengenai pembelajaran berdiferensiasi. Antusiasme peserta terlihat dari keaktifan mengikuti keseluruhan kegiatan pelatihan. Kata kunci: pelatihan; guru; pembelajaran diferensiasi. Abstract The problem faced by these teachers is designing learning that is able to meet the needs of the diverse learning characteristics of students, both regular and children with special needs. One strategy that can be used to achieve this in this era of Independent Learning is Differentiated Learning. The implementation of differentiated learning involves elements that are the focus of 21st century learning. The aim of this training activity is to increase knowledge about differentiated learning so that the quality of learning according to the demands of the 21st century can be met in this era of independent learning. Implementation methods include providing material by resource persons, discussions and questions and answers between participants and resource persons, mentoring and evaluation. The training was conducted on 9 teachers at SMP Negeri 4 Sukowono in May and June 2024. At the end of the training, participants took a posttest and filled out a survey via a response questionnaire, the results of which were measured using a Likert Scale, and obtained an average score of 80 and a score of 87% for the participants' knowledge component. Based on data obtained from the posttest and response questionnaire, it shows that there has been an increase in the training participants' knowledge regarding differentiated learning. The enthusiasm of the participants can be seen from their active participation in all training activities. Keywords: training; teachers; differentiated learning.

Abstract

This study aimed to develop and validate an assessment instrument to measure students’ understanding of Newton’s laws and their nationalism attitudes. The instrument consisted of 15 essay questions on Newton’s laws and a 30-item Likert-scale questionnaire on nationalism attitudes. Content validity was evaluated by eight experts (lecturers, teachers, and peers) using Aiken’s V index, showing high validity. Empirical validation was conducted with 275 students from public senior high schools in Bima Regency, West Nusa Tenggara. Data were analyzed using Item Response Theory with the Partial Credit Model (PCM) via QUEST. Results indicated that all concept understanding items fit the PCM criteria, with acceptable reliability values ranging from 0.72 to 0.98. For the nationalism instrument, 29 items met the fit criteria, while one item was rejected. Overall, the developed instruments demonstrated strong validity and reliability, and are suitable for assessing both cognitive understanding of Newton’s laws and students’ nationalism attitudes.
