Abstract

This study aims to examine the impact of the experimental method on science learning outcomes for 28 third-grade students at Weerame Christian Elementary School, divided equally into experimental (n=14) and control (n=14) groups. The experimental group used direct instruction. Data came from a validated 20-item multiple-choice test. Descriptive analysis revealed notable gains: the experimental group's mean pretest score was 50.68 (range: 35-60), rising to 85.23 posttest (range: 60-95; N-Gain=0.70, high effect). The control group's mean improved from 49.09 (33-75) to 61.45 (40-80; N-Gain=0.24, low effect). Pretest equality was confirmed (mean difference=1.59; p>0.05). Prerequisite tests showed normality (sig.=0.161) but marginal homogeneity (sig.=0.017). Independent Samples t-test yielded sig.=0.000 <0.05, indicating a significant posttest difference favoring the experimental group. It is therefore concluded that the experimental method influences science learning outcomes in third grade at SDM Weerame. Teachers should integrate it into science lessons under Merdeka Curriculum on elementary shcool.

Abstract

The problem in this study is the low mathematics learning outcomes of students, with an average score of 66.5 with only 37.5% of students achieving the minimum mastery criteria. This study aims to determine the effect of the Student Teams Achievement Division (STAD) cooperative learning model on the mathematics learning outcomes of fourth-grade students at SD Katolik Bali Loura. This study employed a quasi-experimental method with a non-equivalent control group design. The sample consisted of 48 students, divided into 24 students in the experimental class and 24 students in the control class. Data were collected through pretest and posttest and analyzed using N-Gain and independent sample t-test. The results showed a significant improvement in learning outcomes, with a significance value of 0.000 < 0.05. This indicates that the STAD cooperative learning model has a significant effect on students mathematics learning outcomes. This study is limited to the cognitive domain, therefore future research is recommended to examine affective and psychomotor aspects in order to obtain more comprehensive results.
