Abstract

This study aims to analyze junior high school students’ critical thinking skills in solving problems related to Systems of Linear Equations in Two Variables (SPLDV). The research employed a descriptive qualitative approach and was conducted at SMP Negeri 9 Kota Jambi involving 32 ninth-grade students. Data were collected through contextual essay-type SPLDV tests designed based on six critical thinking indicators proposed by Facione, namely interpretation, analysis, evaluation, inference, explanation, and self-regulation. In-depth interviews were also conducted to support and clarify the test results. Data analysis followed an interactive model consisting of data reduction, data display, and conclusion drawing. The findings indicate that students’ critical thinking skills have not developed evenly across all indicators. Interpretation skills were relatively better developed, while evaluation, inference, explanation, and self-regulation remained at low levels. Most students were able to identify relevant information and construct mathematical models; however, they experienced difficulties in evaluating solution procedures and drawing logical conclusions. These results highlight the need for mathematics learning strategies that emphasize analytical reasoning, evaluation, and reflective thinking to enhance students’ critical thinking skills, particularly in learning SPLDV.

Abstract

Penelitian ini bertujuan untuk menganalisis kemampuan penalaran matematis siswa SMP dalam menyelesaikan soal pada materi pola bilangan. Latar belakang penelitian didasari oleh fakta bahwa siswa masih mengalami kesulitan dalam mengidentifikasi, mengembangkan, dan menyelesaikan permasalahan yang berkaitan dengan pola bilangan sehingga menghasilkan capaian yang rendah pada aspek penalaran matematis hal ini dikemukakan oleh guru yang mengajar di sekolah tersebut. Penelitian ini menggunakan pendekatan kualitatif dengan jenis penelitian studi kasus. Subjek penelitian dipilih secara purposive sampling berdasarkan hasil tes tertulis kemampuan penalaran, yang terdiri dari siswa dengan kategori kemampuan tinggi, sedang, dan rendah. Data dikumpulkan melalui tes tertulis berupa soal pola bilangan dan wawancara semi-terstruktur. Analisis data dilakukan melalui tahapan reduksi data, penyajian data, dan penarikan kesimpulan. Indikator yang digunakan untuk menilai kemampuan penalaran meliputi mengajukan dugaan, melakukan manipulasi matematika, menemukan suatu pola, dan menarik kesimpulan. Hasil penelitian ini diharapkan dapat memberikan gambaran mendalam mengenai variasi kemampuan penalaran siswa dalam menyelesaikan soal pola bilangan, sekaligus menjadi bahan pertimbangan bagi guru, sekolah, dan peneliti lain dalam merancang strategi pembelajaran matematika yang lebih efektif.

Abstract

This study addresses the limited empirical profiling of emotional labor among early childhood teachers in Indonesia by applying the Rasch Rating Scale Model. The research aims to examine teachers’ tendencies in emotional regulation, identify item difficulty levels, and map teacher ability distributions. A total of 312 early childhood teachers participated by completing an emotional labour scale representing four emotional-regulation dimensions. The reported logit range of −0.85 to 0.75 refers specifically to the distribution of item difficulty, which differs from the later reported teacher logit range (−3.5 to +3.2). The analysis revealed high measurement reliability (item reliability = 0.98; person reliability = 0.70) and satisfactory model fit indices. Teachers predominantly demonstrated reflective and authentic emotional regulation, as operationalised by lower difficulty on deep-acting and natural-expression items, indicating these strategies were more readily performed. These findings highlight that emotional labour among Indonesian early childhood teachers is grounded in empathy, warmth, and affective balance, forming an essential foundation for emotionally responsive and humanistic teaching practices.
