Abstract

Interactive learning has become a necessity in the modern educational era, particularly for facilitating students’ understanding of abstract mathematical concepts such as algebra. Difficulties in comprehending algebraic concepts often hinder the development of students’ critical thinking skills, which are essential for solving problems and making logical decisions. This study aimed to develop Nearpod-assisted interactive learning media and examine its effectiveness in enhancing students’ critical thinking skills in algebra. The study employed the Thiagarajan (4-D) development model, consisting of four stages, namely define, design, develop, and disseminate. The research subjects were selected through purposive sampling and consisted of 31 seventh-grade students (16 females and 15 males) from Class VII G of State Junior High School 4 Jember, Indonesia, who demonstrated low levels of critical thinking skills based on the results of an initial assessment. Data were collected through classroom observations, critical thinking tests, and student response questionnaires. The effectiveness of the developed media was evaluated by testing the research hypothesis regarding the impact of Nearpod-assisted learning on students’ critical thinking skills. Data were analyzed using a paired-samples t-test and N-Gain analysis. The t-test results showed a significance value (Sig. 2-tailed) of 0.000 (< 0.05), indicating a significant difference between the mean pre-test and post-test scores. Furthermore, the N-Gain percentage reached 80.19%, indicating a high level of improvement. These findings suggest that Nearpod-assisted interactive learning media is effective in improving students’ critical thinking skills in algebra and positively contributes to their learning outcomes at State Junior High School 4 Jember.

Abstract

Critical thinking is very necessary to face the development of the era that continues to develop. The international instrument that is often used to measure mathematical critical thinking skills is the Programme for International Student Assessment (PISA). This qualitative research with a descriptive approach aims to describe the process of students' mathematical critical thinking in solving PISA questions on the content of change and relationship in terms of self-regulated learning. The subjects of this study were one subject with a high self-regulated learning category and one subject with a moderate self-regulated learning category in grade VIII. The selection of subjects was based on the results of the self-regulated learning questionnaire criteria and the results of critical thinking tests. The results of the analysis obtained showed that students with high self-regulated learning had a superior mathematical critical thinking process compared to students with moderate self-regulated learning. Subjects with high self-regulated learning not only understood the questions well, but were also able to analyze them in depth, evaluate the results of their work, and draw logical and relevant conclusions. In contrast, subjects with moderate self-regulated learning were still able to solve the questions, but with simpler strategies and less in-depth thinking. They tended to follow standard procedures without further exploration of the concepts underlying problem solving.

Abstract

Proses berpikir aljabar siswa tercermin dari cara mereka menyelesaikan soal kontekstual. Penyelesaian soal kontekstual memungkinkan siswa mengembangkan pola pikir yang lebih kompleks karena melibatkan pengetahuan matematika formal dan informal. Variasi pendekatan siswa dalam menyelesaikan masalah tidak hanya dipengaruhi oleh kemampuan kognitif, tetapi juga oleh faktor nonkognitif yaitu tipe kepribadian dan salah satu teori yang digunakan untuk mengklasifikasikan tipe kepribadian adalah Hippocrates–Galenus. Pendekatan yang digunakan adalah deskriptif kualitatif dengan tiga subjek kelas VIII, satu siswa bertipe Sanguinis dan dua siswa bertipe Plegmatis. Subjek tersebut dipilih secara purposive berdasarkan skor angket serta kemampuan komunikasi mereka. Data diperoleh melalui tes berpikir aljabar, observasi, dan wawancara, kemudian dianalisis melalui tahapan reduksi data, penyajian data, dan penarikan kesimpulan. Keabsahan data dijamin melalui teknik triangulasi metode. Hasil penelitian menunjukkan bahwa subjek Sanguinis mampu mengenali pola, menyusun rumus umum, dan menyimbolkan informasi, meskipun pemahaman hubungan antarvariabel masih bersifat konseptual. Pemodelan yang dilakukan belum konsisten, strategi analitik bersifat intuitif, dan pengorganisasian cenderung kurang terstruktur. Sementara itu, subjek Plegmatis mampu mengenali pola dan menyusun rumus, namun hanya memahami hubungan antarvariabel secara konseptual, cenderung tidak mengembangkan model atau menghasilkan model yang kurang tepat, serta menunjukkan hasil kerja yang kurang terorganisasi.
