Abstract

This study investigates the impact of creative thinking skills, specifically through the Widening, Connecting, and Reorganizing (WCR) model, on the cognitive learning outcomes of junior high school students at SMPK Sint Vianney Soe. Creative thinking is recognized as a pivotal 21st-century competency that not only empowers students to devise innovative solutions but also influences their learning achievements. However, the relationship between creative thinking skills, particularly the WCR model, and cognitive learning outcomes has not been thoroughly explored. This research addresses this gap using a descriptive-correlational design, collecting data from 55 students through validated instruments. The findings revealed a significant relationship between creative thinking skills and cognitive learning outcomes, represented by the regression equation Y=26.354+0.691X. The analysis showed that 69.7% of the cognitive learning outcomes are influenced by creative thinking skills. Among the WCR dimensions, the widening aspect demonstrated the strongest correlation with cognitive outcomes, followed by the connecting aspect, while the reorganizing aspect was not significantly related to cognitive learning outcomes.

Abstract

The Pulsed Nuclear Magnetic Resonance (PNMR) technique is a widely used spectroscopic approach for observing the relaxation phenomena of atomic nuclei in a magnetic field. In this technique, the spin-lattice (T1) and spin–spin (T2) relaxation times are key parameters, as they reflect the microscopic dynamics and structure of a material system. This article presents the results of a systematic literature review of fourteen primary references that discuss the fundamental concepts of NMR, PNMR techniques, the measurement of T1 and T2, and PNMR applications. Although NMR research has seen extensive development internationally, scientific literature in the Indonesian language that specifically addresses this topic remains scarce. Therefore, this paper is intended to serve as an initial systematic resource to introduce the basic principles and potential applications of PNMR in physics and materials science.

Abstract

Problem-solving skills through the STEM approach are currently also being examined in relation to gender differences. This study aims to describe students’ problem-solving skills and compare them based on gender in the topic of thermodynamics using the STEM approach. The research employed a descriptive quantitative method involving 86 grade 11 science students, consisting of 51 female and 35 male students. The problem-solving indicators used include Useful Description, Physics Approach, Specific Application of Physics, Mathematical Procedure, and Logical Progression. Data were analyzed using descriptive statistics and comparative tests. The results showed that, in general, students’ problem-solving abilities were in the “good” category. The comparative analysis revealed that female students outperformed male students in the Useful Description and Logical Progression indicators, while male students showed higher performance in Specific Application of Physics and Mathematical Procedure. No significant difference was found between the two groups in the Physics Approach indicator. Overall, the total score of students’ problem-solving skills indicated no significant difference between female and male students. These findings suggest that the STEM approach fosters equitable opportunities for both genders to develop physics problem-solving skills, despite differences in specific indicator strengths. Therefore, STEM-based learning should be designed contextually and inclusively to accommodate students’ diverse potentials and cognitive styles in a balanced manner.

Abstract

Beberapa konsep abstrak seperti arus, tegangan, dan hambatan dalam materi kelistrikan fisika sering kali menjadi tantangan besar dalam proses pembelajaran. Hal ini menuntut adanya inovasi media pembelajaran yang konkret dan interaktif. Artikel ini mengkaji efektivitas media pembelajaran interaktif berbasis rangkaian digital melalui studi literatur sistematis terhadap tujuh sumber ilmiah dalam 10 tahun terakhir. Fokus utama kajian adalah pemanfaatan komponen IC LM324, LM339, serta gerbang logika TTL 7408 dan 7486 untuk memvisualisasikan alat hukum Ohm dan hukum Kirchhoff. Hasil kajian menunjukkan bahwa media ini dapat meningkatkan pemahaman siswa dengan memvisualisasikan konsep kelistrikan secara nyata dan mendorong pembelajaran aktif. Media ini dinilai efektif, mudah dirakit, ekonomis, serta sesuai dengan konteks sekolah menengah dengan keterbatasan sarana. Selain itu, pendekatan ini berkontribusi dalam pengembangan keterampilan berpikir kritis dan kemampuan eksplorasi siswa. Penelitian menyarankan agar pengembangan media didukung dengan pelatihan guru dan integrasi ke dalam kurikulum. Dengan demikian, media ini berfungsi sebagai alat bantu belajar sekaligus sarana eksplorasi untuk memperkuat pembelajaran berbasis proyek dan teknologi di era digital.
