Abstract

The purpose of this research is to examine the physics literacy skills of students solving HOTS questions and self-regulated learning (SRL) on measurement material at private high schools in Maju Village, through descriptive research using a qualitative approach. The instruments used include questionnaires, and HOTS test questions on Measurement material. The results showed that the low SRL category (score 98) was unable to reach the questions at C4. The medium group (score 120), could not fulfill all level 4 indicators. In high SRL, students are able to fulfill the indicators, by solving the problem completely, using the right information, applying numeracy skills, and being able to provide conclusions and their reasons, but cannot fulfill the indicators at level 5 and 6. The learning independence factor plays a significant role in determining the level of HOTS student.

Abstract

This study employed classroom action research with the aim of enhancing students' physics problem-solving skills using Problem-Based Learning (PBL) supported by student worksheets (Lembar Kerja Peserta Didik/LKPD). The research targeted 10th-grade high school students focusing on the topic of Measurement. The methodology followed a cycle comprising four stages: planning, action, observation, and reflection. At the end of each cycle, evaluations were conducted using a validated test instrument consisting of four essay questions. The success criterion was set at a minimum of 70% of students achieving a mastery level, defined by a score of at least 65. During the pre-cycle phase, before applying PBL, the initial test results revealed no students achieved mastery, with an average problem-solving score of 54.67. Subsequently, two cycles of PBL implementation were carried out. In the first cycle, 15 students reached the mastery criterion, representing 41.17% improvement in problem-solving skills, with an average score of 63.75. Building on this progress, the second cycle was implemented, resulting in 29 students achieving mastery. This represented 80.05% of the class, categorized as a moderate improvement, with an average problem-solving score of 70.05. These findings indicate a significant enhancement in students' physics problem-solving abilities through the integration of PBL and LKPD. This approach effectively facilitated active student engagement and critical thinking, demonstrating its potential as an impactful instructional strategy in high school physics education.

Abstract

Penelitian ini bertujuan untuk mengetahui model pembelajaran yang digunakan guru fisika di Sumatra utara. Penelitian ini menggunakan metode observasi dan memiliki pendekatan kuantitatif. Kegiatan ini dilakukan agar dapat memperoleh data dari sampel yang sudah ditargetkan sebanyak 5 guru yang berada di Sumatra Utara. Teknik yang digunakan Penelitian ini dilakukan dengan menggunakan wawancara secara online menggunakan WhatsApp dan google Form. Hasil observasi menunjukkan bahwa model pembelajaran yang digunakan guru 1. pembelajaran inkuiri dan pembelajaran berbasis masalah (PBL), 2. Pembelajaran berbasis projek, dan pembelajaran berbasis masalah, 3. Pembelajaran berbasis masalah dan projek, 4. Pembelajaran berbasis masalah, 5. Pembelajaran berbasis masalah dan pembelajaran berbasis projek. Berdsarkan hasil observasi diperoleh model pembelajaran yang digunakan ialah pembelajaran inkuiri, pembelajaran berbasis masalah (PBL), pembelajaran berbasis projek (PjBL). Dan dari hasil observasi juga ditemukan bahwa banyak guru yang kurang mengetahui tata cara (Sintaks) pelaksanaan suatu model yang tepat.

Abstract

Physics learning practices in schools are still largely dominated by monotonous, teacher-centered approaches, which contribute to low student engagement and academic achievement. This study aims to improve student activeness and Physics learning outcomes through the implementation of the Inquiry Learning model based on the Merdeka Belajar (Freedom to Learn) concept. The research employed a Classroom Action Research (CAR) design conducted in two cycles. The subjects of this study were 25 tenth-grade students at SMA Desa Maju. Instruments used included multiple-choice tests to measure learning outcomes and observation sheets to assess student engagement. The results indicated a significant improvement, with the average learning score increasing from 29.00 in the pre-cycle to 47.50 in the first cycle, and reaching 87.83 in the second cycle. Student engagement also improved progressively in each session. These findings demonstrate that the implementation of the Inquiry Learning model based on the Merdeka Belajar concept is effective in enhancing both engagement and Physics learning outcomes.
