Abstract

Multiplication learning at the elementary school level requires an approach that focuses not only on procedures but also on students' understanding of the concepts. One strategy used in education is the use of educational programs as components of learning activities. The purpose of this study was to analyze the effect of educational programs on the learning outcomes of fourth-grade students at SDIT Tahfidz Bintangku, Probolinggo City. This study was conducted on January 14, 2026, using a quantitative approach with a single-group pretest-posttest design. Thirty-three students were included in the study. The Wilcoxon Signed Rank Test was used to analyze the learning data because the data did not violate the assumption of normality. Furthermore, N-Gain analysis and effect size were used to enhance the interpretation of the research results. Keywords: Educational Games, Multiplication, Learning Outcomes, Elementary School

Abstract

This study was inspired by fifth-grade elementary school students' poor performance in mathematics, particularly in plane figures, due to the widespread use of the lecture method, which tends to make students docile and unmotivated. Therefore, the purpose of this study is to ascertain how the Discovery Learning approach affects the academic performance of thirty fifth-grade students at SDIT Tahfidz Bintangku in Probolinggo City, particularly in the field of plane figures. Any causal interpretation must take into consideration risks to internal validity because the approach was a quantitative study using a pre-experimental design of the one-group pretest-posttest type without a control group. The study used written pretest and posttest instruments, whose reliability was evaluated using Cronbach's Alpha (α = 0.87, high category) and whose validity was evaluated using Pearson's product-moment correlation. With a significance level of 0.000 < 0.05 and an average N-gain Score of 0.42 (moderate category) and a Cohen's Effect Size of 1.23 (large effect category), data analysis using the Paired Samples t-Test with IBM SPSS Statistics showed an increase in the mean score from 40.83 on the pre-test to 65.73 on the post-test; as a result, H1 is accepted. Therefore, it can be said that the Discovery Learning approach significantly improves fifth-grade elementary school students' learning outcomes in the area of plane figures; however, given the limitations of the research design, which did not include a control group, causal generalizations should be made with caution.

Abstract

The Three-Variable Linear Equation System (SPLTV) is an essential topic in the Grade X senior high school mathematics curriculum that requires deep conceptual understanding; however, preliminary observations revealed that 60% of students scored below the Minimum Completeness Criteria (KKM), attributed to conventional teacher-centered instruction that had not optimally facilitated conceptual understanding. This study aims to analyze the use of NotebookLM in supporting students' conceptual understanding of SPLTV in Grade X. The research employed a descriptive qualitative approach with instruments consisting of test questions, questionnaires, and interview guidelines, analyzed using the interactive model of Miles, Huberman, and Saldaña. The research subjects were 30 female students of Grade X at SMAIT Kyai Sekar Al-Amri, Probolinggo. The results showed that all students obtained test scores ranging from 80–100 with an average of 91.33, along with positive responses from the questionnaires and interviews regarding the ease of use and benefits of NotebookLM, although some students still experienced difficulties in determining the appropriate solving method and therefore still required teacher guidance.
