Abstract

The mismatch of learning models with student competencies has the potential to inhibit classroom interaction and reduce learning engagement. This impact is seen in the decline of academic achievement. An effective solution is the implementation of Project Based Learning (PjBL), a student-centred approach based on creative-innovative methods. This study examined the effect of PjBL on improving learning outcomes using a quantitative experimental design. The research subjects consisted of students of class VII A (experimental) and VIII B (control) at SMP Negeri 1 Tompaso Baru.. Based on the results of research using the t-test, obtained tcount= 3.605 and ttable value at a significant level α = 0.05 and df = 38 is 1.685, thentcount> ttable (3.605> 1.685). This shows that the Project Based Learning (PjBL) learning model is higher than the conventional learning model on student learning outcomes in social artimatics class VII SMP Negeri 1 Tompaso Baru.

Abstract

This study aims to develop a social arithmetic teaching module based on the Indonesian Realistic Mathematics Education (PMRI) approach that is valid, practical, and effective in supporting the numeracy skills of junior high school students. The low numeracy achievement of Indonesian students, reflected in the 2022 Programme for International Student Assessment (PISA) score of 366, together with the limited availability of contextual teaching materials, motivated this research. The study employed the Research and Development method using the Plomp model, which comprises three phases: preliminary research, the development or prototyping phase, and the assessment phase. The research subjects were seventh-grade students of SMP Katolik Don Bosco Bitung in the 2025/2026 academic year. Data were collected through expert validation sheets, teacher and student practicality questionnaires, and numeracy tests (pretest and posttest), then analysed using percentage scores and the N-Gain formula. The results show that the module met the highly valid criteria with percentages of 90% from the material expert and 91.7% from the media expert, while the test instrument reached 90%. The practicality aspect was categorised as highly practical based on the one-to-one trial (85.2%), small-group trial (88.8%), and field test (85.34%). The module's effectiveness was demonstrated by an increase in students' average scores from 28.63 on the pretest to 65.91 on the posttest, with an N-Gain value of 0.51 in the medium category. Therefore, the developed PMRI-based social arithmetic module is feasible for use as teaching material that supports the numeracy skills of junior high school students.

Abstract

This research aimed to evaluate the effectiveness of the Teaching at the Right Level (TaRL) approach on student learning outcomes regarding relations and functions. This experimental study employed a pretest-posttest control group design at State Junior High School 5 Manado. The experimental class was taught using the TaRL approach, while the control class received Direct Instruction. Results indicated that the average learning outcomes of the experimental class (81.80) significantly outperformed the control class (71.48). Hypothesis testing via t-test yielded tcount = 3.619 > ttabel = 2.011 at a significance level of 0.05, confirming significant difference. Furthermore, TaRL met all effectiveness criteria: 1) the average score exceeded the learning objective attainment threshold (KKTP) of 75;2) classical mastery was achieved; 3) student responses to the learning process were positive. In conclusion, the TaRL approach is effective in improving student learning outcomes for relations and functions material among eighth-grade students.
