Abstract

This study aims to describe the implementation of the problem-solving method in learning measurement of length and weight for third-grade elementary school students and to determine ist effect on students’ learning outcomes and participation. The background of this study is based on the low understanding of students regarding measurement concepts due to teacher-centered learning and the lack of student involvement in solving real-life problems. The problem-solving method was chosen because it can train students to think critically, actively participate, and develop skills in solving problems related to daily life. This study used a descriptive qualitative approach with third-grade elementary school students as the research subjects. Data collection techniques included observation, interviews, documentation, and learning outcome tests. The results showed that the implementation of the problem-solving method improved students’ understanding of length and weight measurement concepts. Students became more active in discussions, were able to cooperate effectively in groups, and showed greater confidence in expressing opinions and providing solutions to the given problems. In addition, students’ learning outcomes increased after the implementation of the method. Therefore, the problem-solving method is considered effective for mathematics learning, especially in the topic of measuring length and weight for third-grade elementary school students.

Abstract

Mathematical problem solving skills are one of the key competencies that need to be developed starting in elementary school, as they play a role in enhancing students’ logical, critical, and creative thinking abilities. However, in reality, many students still struggle with solving math problems, particularly those involving contextual problems. This situation highlights the need to implement learning strategies that actively engage students in the learning process. This study aims to determine the effect of using the Problem Based Learning (PBL) strategy on improving the mathematical problem solving skills of second grade elementary school students. The research method used is quantitative research with a pre-experimental design employing a one-group pretest posttest design. The research subjects were second grade elementary school students selected using purposive sampling. Data collection was conducted through mathematics problem-solving ability tests administered before and after the implementation of the PBL strategy. The data were analyzed using descriptive statistics and hypothesis testing to determine the differences in students’ abilities before and after the intervention. The results of the study indicate that the implementation of the Problem Based Learning strategy significantly improved students’ mathematics problem-solving abilities. Thus, the Problem Based Learning strategy can serve as an effective alternative learning method to improv.

Abstract

This study aimed to examine the effect of implementing the Project Based Learning (PjBL) model on the mathematics learning outcomes of second-grade students at SD Integral Hidayatullah Probolinggo in the topic of multiplication and division operations. The study employed a quantitative approach using a one-group pre-test–post-test experimental design. Data were collected through pre-test and post-test instruments to measure students' learning outcomes before and after the implementation of the PjBL model. Data analysis was conducted using IBM SPSS Statistics, including descriptive statistical analysis, the Kolmogorov–Smirnov and Shapiro–Wilk normality tests, and the Mann–Whitney U non-parametric test because the data did not meet the assumption of normality. The analysis yielded an Asymp. Sig. (2-tailed) value of 0.000 (p < 0.05), indicating a statistically significant difference between the pre-test and post-test results. The findings suggest that the implementation of the Project Based Learning model had an effect on students' mathematics learning outcomes in multiplication and division operations. Therefore, the PjBL model can serve as an alternative instructional approach to promote active, contextual, and student-centered learning through project-based activities.

Abstract

The low critical thinking skills of 10th-grade high school students regarding arithmetic sequences and series are attributed to a lack of student engagement during the mathematics learning process. This study aims to determine the effect of implementing the question-and-answer method on improving students' critical thinking skills in the topic of arithmetic sequences and series. A quantitative approach was employed using a quasi-experimental design—specifically, a pretest-posttest control group design. The research subjects consisted of 26 10th-grade students from MA Wahid Hasyim during the 2025/2026 academic year. Data collection involved pretests, posttests, and observation sheets. Data analysis was conducted using normality and t-tests with the aid of IBM SPSS Statistics. The results indicate that the question-and-answer method successfully improved students' critical thinking skills, evidenced by the rise in the average score from 75 on the pretest to 88 on the posttest. Furthermore, the t-test yielded a significance value of 0.001 (p < 0.05), demonstrating that the question-and-answer method had a significant impact on enhancing students' critical thinking skills regarding arithmetic sequences and series.

Abstract

Geometri merupakan salah satu cabang matematika yang memiliki peran fundamental dalam sistem pendidikan sekolah menengah pertama, namun siswa sering mengalami kesulitan dalam menyelesaikan soal-soal geometri yang melibatkan proses kognitif kompleks seperti pemahaman konsep, penalaran logis, dan visualisasi spasial. Penelitian ini bertujuan untuk menganalisis kesulitan siswa dalam menyelesaikan soal geometri pada siswa SMP kelas VII. Metode penelitian yang digunakan adalah kualitatif deskriptif dengan teknik pengumpulan data melalui tes, wawancara, dan kuesioner yang dianalisis menggunakan triangulasi data. Subjek penelitian adalah 30 siswa kelas VII SMP Darul Akhlaq Kabupaten Probolinggo yang terdiri dari 15 siswa laki-laki dan 15 siswa perempuan. Hasil penelitian menunjukkan bahwa mayoritas siswa mengalami kesulitan signifikan dalam memahami konsep geometri, terutama dalam mengingat rumus (86,7%), membayangkan bentuk bangun (80%), dan memahami konsep luas (76,7%). Kesulitan ini berakar pada fondasi pemahaman yang lemah sejak awal pembelajaran dan metode pengajaran konvensional yang bersifat teacher-centered. Penelitian ini merekomendasikan implementasi pembelajaran kolaboratif dengan pendekatan konstruktivis yang lebih konkret dan visual untuk meningkatkan pemahaman geometri siswa.

Abstract

This study aims to analyze the effect of the Direct Instruction model on improving students’ mathematical conceptual understanding in the Pythagorean Theorem topic for eighth-grade students. This research employed a quantitative approach using a pre-experimental method with a One-Group Pretest-Posttest Design. The participants consisted of 30 eighth-grade students at MTs Bustanul Ulum selected through purposive sampling. Data were collected using an essay-based mathematical conceptual understanding test administered before and after the treatment. Data analysis was conducted using descriptive statistical analysis, normality testing, Paired Sample t-Test, Wilcoxon Signed-Rank Test, and Normalized Gain (N-Gain) analysis. The results showed that the students’ mean score increased from 67.50 in the pretest to 85.17 in the posttest, with an improvement of 17.67 points. The Paired Sample t-Test showed a significance value of 0.000 < 0.05 with a t-value of 13.293, while the Wilcoxon Signed-Rank Test also indicated a significance value of 0.000. The N-Gain analysis resulted in a score of 0.5422 or 54.22%, which was categorized as moderate and sufficiently effective. These findings indicate that the Direct Instruction model effectively improves students’ mathematical conceptual understanding through structured learning activities, explicit explanations, guided practice, and continuous feedback. Therefore, the Direct Instruction model can be considered an effective alternative strategy for mathematics teachers to enhance students’ understanding of the Pythagorean Theorem concept.

Abstract

This study aims to determine the effect of the storytelling method on students' Indonesian language learning outcomes in the topic of personal experiences among third-grade elementary school students. The topic of personal experiences is an essential component of Indonesian language learning because it helps students develop language skills, express ideas, and improve their speaking and writing abilities. However, based on classroom observations, many students still experienced difficulties in understanding and recounting their personal experiences in a coherent and engaging manner. Therefore, an instructional method that actively engages students in the learning process is needed. The storytelling method was selected because it enables students to understand the learning material through meaningful, engaging, and contextualized stories. This study employed a quantitative approach using a pre-test and post-test research design. The participants consisted of 26 third-grade elementary school students. The research instruments included pre-test and post-test questions. The data were analyzed using IBM SPSS Statistics through normality testing and the Mann–Whitney test. The results indicated that the students' mean score increased from 48.65 on the pre-test to 56.35 on the post-test. However, the Mann–Whitney test revealed a significance value of 0.110 (p > 0.05), indicating that the improvement was not statistically significant. Nevertheless, the storytelling method demonstrated a positive tendency to improve students' learning outcomes in the topic of personal experiences.
