Abstract

Penelitian ini bertujuan untuk menganalisis tingkat kemampuan pemecahan masalah peserta didik SMA pada materi suhu dan kalor. Subjek penelitian ini adalah peserta didik kelas X salah satu SMA di kota Merauke yang berjumlah 30 orang. Metode yang digunakan dalam penelitian ini bersifat deskriptif dan data diperoleh dengan memberikan instrumen berupa tes kemampuan pemecahan masalah. Adapun instrumen yang digunakan adalah instrumen kemampuan pemecahan masalah berbasis multimodus representasi Rosengrant yang telah dikembangkan peneliti dan telah diuji validitas dan reliabilitasnya sehingga dinyatakan layak untuk digunakan sebagai instrumen tes. Selain itu, wawancara juga dilakukan terhadap guru sebagai data pendukung. Hasil yang diperoleh menunjukkan bahwa tingkat kemampuan pemecahan masalah peserta didik pada tahap 1 dan tahap 4 lebih baik daripada tahap 2 dan tahap 3.

Abstract

This community service program aims to enhance students’ problem-solving abilities in physics through the synergy of Problem-Based Learning (PBL) and learning assistance at SMA YPPK Yoanes XXIII Merauke. The implementation methods included: (1) socialization sessions for parents and teachers; (2) training for grade X students; and (3) mentoring for grade X students through PBL and the use of measuring instruments. The instruments used were tests validated by expert teams, while questionnaires were administered to assess parents’ understanding and students’ responses. Data were analyzed using descriptive analysis techniques. The results of this community service activity indicate that: (1) 90% of parents understood the importance of providing their children with additional lessons or tutoring; (2) students’ physics problem-solving skills improved by 77%; and (3) 14 students recognized the need for additional tutoring in physics. Overall, the program successfully strengthened students’ problem-solving abilities and increased awareness among both students and parents regarding the importance of continuous learning support.

Abstract

Physics instruction that relies solely on conventional learning models is one of the factors contributing to students’ low critical thinking skills. This study aimed to examine the effect of the Problem-Based Learning (PBL) model based on a Problem-Solving Strategy on the critical thinking skills of eleventh-grade students at State Senior High School 2 Merauke in the topic of particle motion dynamics. This quantitative study employed a quasi-experimental research method using a pretest–posttest control group design. The sample consisted of class XI-4 as the experimental group and class XI-6 as the control group, selected through purposive sampling. The research procedure comprised three main stages: the preparatory stage (problem identification, literature review, development of instructional modules, and construction and validation of research instruments), the implementation stage (administration of the pretest, implementation of the intervention, and administration of the posttest), and the final stage (data analysis and formulation of conclusions). This study adopted Facione’s indicators of critical thinking skills, based on their relevance and alignment with the operational definition of critical thinking employed in this research. The results showed that the experimental class achieved a higher percentage than the control class, demonstrating that the PBL model based on a Problem-Solving Strategy had a greater impact on improving critical thinking skills compared to conventional learning models.
