Abstract

This study is motivated by the low mathematics learning outcomes of students on whole numbers up to 1,000 in grade III of SD N Mampir, caused by teacher-centered learning models. This study aims to determine the effect of implementing the Discovery Learning model on students' mathematics learning outcomes. This research uses a quantitative approach with a Quasi-Experimental Design method in the form of a Nonequivalent Control Group Design. The population comprises all grade III and IV students of SD N Mampir. The sampling technique employed saturated sampling, resulting in 40 grade III students as the experimental group and 40 grade IV students as the control group. The data collection instrument consisted of 20 multiple-choice test items. Data analysis techniques included descriptive statistics, prerequisite tests (Shapiro-Wilk and Levene's Test), and hypothesis testing using the Independent Sample T-Test with IBM SPSS Statistics 21. The results showed that the average posttest score of the experimental group was 21.25, higher than the control group at 18.58. The hypothesis test obtained a significance value of 0.000 < 0.05, so H₀ is rejected and Hₐ is accepted. This proves a significant effect of the Discovery Learning model on mathematics learning outcomes. Teachers are recommended to implement this model routinely to improve students' activeness and mathematical concept understanding.

Abstract

This study aims to describe teacher strategies in character building for students with diverse learning characteristics at SD Negeri Rawailat Cileungsi. Using a descriptive qualitative approach, data were collected through in-depth interviews with four key informants and participatory observation. Data validity was tested through source and technique triangulation, as well as member checking. The results indicate that character building does not rely on a uniform approach, but rather on concrete and repetitive differentiated strategies. The primary strategies include: (1) adjusting targets into micro-steps; (2) affective approach by building emotional connections; (3) direct modeling and experiential learning; (4) language adjustment and use of visual media; (5) structured routines; and (6) heterogeneous grouping. The main supporting factors are functional collaboration among teachers and synergy with parents, while inhibiting factors include large class sizes and the absence of specific planning documents. Teachers respond through creative adaptive efforts such as a tiered monitoring system and home visits. This study concludes that character internalization requires consistency in adaptive strategies and a supportive ecosystem within the framework of the Merdeka Curriculum.
