Abstract

This study aims to examine the effectiveness of the Project Based Learning (PjBL) model in improving seventh-grade students’ creativity and numeracy skills at MTs NW Pringgarata. The main issue addressed is the low level of creativity and numeracy skills caused by conventional teaching methods. A quantitative quasi-experimental design was employed, involving two groups: an experimental class implementing PjBL and a control class using traditional methods. Research instruments included creativity and numeracy tests, supported by assessment rubrics, with data collected through pretests and posttests. Data analysis applied t-tests and N-Gain calculations. The results show that PjBL significantly improves students’ creativity and numeracy skills. The experimental class achieved higher posttest scores than the control class, with an N-Gain of 0.60 (moderate category) compared to 0.49 (moderate category). These findings indicate that PjBL is an effective and innovative alternative teaching method to enhance students’ creativity and numeracy skills.

Abstract

This study aims to develop of instrument  Problem Based Learning (PBL)-based Student Worksheet (LKPD) on the topic of Linear Equation in One Variable (SPLSV) for eighth-grade students at SMP IP Darul Hukumaini Jonggat. The research employed Research and Development (R&D) with Borg and Gall’s model, consisting of problem identification, information gathering, product design, expert validation, trials, and revisions. The participants were 7 students from class VIII A (small-scale trial) and 17 students from class VIII B (large-scale trial). Validation by material and media experts showed that the LKPD achieved the "very valid" criteria with an average score of 98.82%. Teachers’ and students’ responses indicated that the product was practical and highly practical in use. Thus, the developed PBL-based LKPD is feasible to be applied as a learning material to improve students’ understanding of SPLSV

Abstract

Penelitian ini bertujuan untuk mengetahui pengaruh model pembelajaran Problem Based Learning (PBL) terhadap kemampuan komunikasi matematis dan motivasi belajar siswa kelas VIII MTs Nurul Haq. Metode penelitian menggunakan pendekatan kuantitatif dengan desain quasi eksperimen berbentuk Nonequivalent Control Group Design. Sampel penelitian adalah dua kelas: VIII A (kontrol) dan VIII B (eksperimen), masing-masing 28 siswa. Instrumen penelitian meliputi tes uraian untuk mengukur kemampuan komunikasi matematis dan angket untuk mengukur motivasi belajar.Hasil penelitian menunjukkan rata-rata nilai pretest dan posttest kelas kontrol sebesar 47,58 dan 50,00, sedangkan kelas eksperimen 46,73 dan 83,04. Uji t menghasilkan p < 0,05, menandakan perbedaan signifikan antara kedua kelas. Analisis N-gain menunjukkan kategori sedang untuk kontrol (0,44) dan eksperimen (0,54). Penerapan PBL terbukti efektif meningkatkan komunikasi matematis (representasi, penyusunan model, penyajian ide) dan motivasi belajar siswa (partisipasi aktif, ketekunan, dan kepercayaan diri).

Abstract

This study aims to analyze the effectiveness of the Problem-Based Learning (PBL) model in improving students' mathematical conceptual understanding and mathematical disposition. The research employed an experimental design with a quantitative approach. The sample consisted of 38 eighth-grade students of SMP IP Darul Hukumaini, comprising 20 students in the experimental group and 18 in the control group. Research instruments included a mathematical conceptual understanding test and a mathematical disposition questionnaire. Data analysis involved validity testing, reliability, normality test, and t-tests. Findings revealed a significant improvement in the experimental group’s conceptual understanding, with higher posttest scores compared to pretest (t = 8.09 > 2.09). However, no significant difference was found between the experimental and control groups’ posttest results (t = 0.245 < 2.03). Students’ mathematical disposition also showed positive improvement through PBL. These findings highlight that PBL is effective in enhancing both cognitive and affective aspects, although its implementation should be supported by further strategies for optimal outcomes.
