Abstract

This study aims to analyze the scientific communication skills of junior high school students who participate in robotics extracurricular activities through STEM-based learning with the Transcript-Based Lesson Analysis (TBLA) approach. The research was conducted at Nurul Ilmi 1 Integrated Islamic Junior High School, Jambi City, involving four groups of robotics extracurricular students. Each group is involved in the robot creation and testing project, and the interactions between group members during the activity are recorded, transcribed and analyzed using TBLA instruments. The analysis was carried out in a descriptive quantitative manner by calculating the frequency of the occurrence of six indicators of scientific communication, which were then converted into percentages. This process is done with the help of an excel application. Preliminary results show that the most dominant indicators are the ability to convey work verbally and the use of simple scientific terms, while the indicator asking about how robots work appears the least. These results provide an overview of students' scientific communication tendencies in the context of robotics activities, as well as provide a basis for the development of STEM learning models that can improve students' scientific communication skills through non-formal approaches

Abstract

Penelitian ini bertujuan untuk menganalisis efektivitas pembelajaran terhadap peningkatan pemahaman siswa pada materi gerak parabola menggunakan desain pretest–posttest. Subjek penelitian terdiri dari 22 siswa kelas XI SMA Negeri 10 Kota Jambi. Instrumen penelitian berupa tes hasil belajar berjumlah 20 soal yang diberikan sebelum dan sesudah pembelajaran. Data dianalisis menggunakan statistik deskriptif, normalized gain, dan uji paired sample t-test. Hasil penelitian menunjukkan rata-rata nilai pretest sebesar 47,27 dan meningkat menjadi 79,09 pada posttest, dengan selisih peningkatan sebesar 31,82 poin. Perhitungan normalized gain menghasilkan nilai 0,57 yang termasuk kategori sedang, sehingga menunjukkan bahwa pembelajaran cukup efektif dalam meningkatkan pemahaman siswa.. Temuan ini menunjukkan bahwa pembelajaran fisika yang terstruktur dan berfokus pada analisis konsep mampu memberikan peningkatan yang nyata terhadap pemahaman siswa pada materi gerak parabola. Penelitian ini dapat menjadi rujukan bagi guru dalam merancang strategi pembelajaran yang lebih efektif pada materi kinematika dua dimensi
