Abstract

Reading ability is a fundamental skill that elementary school students need to master as a foundation for successful learning. However, observations conducted at SDN 1 Kerjo, SDN 2 Jati, and SDN 2 Jatiprahu indicated that the reading ability of first-grade students was still low, as demonstrated by difficulties in recognizing letters, reading syllables, reading words, and comprehending simple texts. This study aimed to analyze the effect of using the Early Grade Reading Assessment (EGRA) Free on the reading ability of first-grade elementary school students. The study employed a quantitative approach with a quasi-experimental method using a Non-Equivalent Pretest–Posttest Control Group Design. The sample consisted of 33 students selected through purposive sampling and divided into an experimental group and a control group. The research instrument was a 20-item reading ability test administered as a pretest and posttest. The normality test results indicated that all data were normally distributed, with significance values of 0.347 and 0.524 for the pretest and posttest of the control group, respectively, and 0.174 and 0.389 for the experimental group, respectively (>0.05). The homogeneity test using Levene’s test yielded a significance value of 0.371 (>0.05), indicating that the data were homogeneous. The N-Gain analysis showed that the improvement in reading ability in the experimental group was higher than that in the control group. Furthermore, the results of the independent samples t-test indicated a significant difference between the two groups. Therefore, it can be concluded that the use of EGRA Free had a positive effect on the reading ability of first-grade elementary school students.

Abstract

Learning media play an important role in helping students understand the concepts of Natural and Social Sciences (IPAS) through concrete learning experiences. However, the learning process on sound-related topics in elementary schools is still predominantly conducted through lecture methods, causing students to experience difficulties in understanding the abstract concept of sound propagation. This study aimed to determine the effect and effectiveness of using recycled-material tin-can telephone learning media on the cognitive learning outcomes of fifth-grade elementary school students in IPAS, particularly on the topic of sound. This study employed a quantitative approach using a quasi-experimental method with a Nonequivalent Control Group Design. The sample consisted of 20 students, comprising 10 students in the experimental class and 10 students in the control class. Data were collected using tests administered as pretests and posttests. Data analysis was conducted using normality and homogeneity tests, an Independent Samples t-test, and an N-Gain test. The results showed that the use of tin-can telephone media had a statistically significant effect on students' cognitive learning outcomes, with a significance value of 0.000 (<0.05). The mean posttest score of the experimental class was 93.5, which was higher than that of the control class at 80.5. The N-Gain analysis showed that the experimental class achieved an N-Gain score of 79.3690%, categorized as effective, while the control class achieved an N-Gain score of 35.5595%, categorized as ineffective. Therefore, the use of recycled-material tin-can telephone learning media had a significant and effective effect on improving the cognitive learning outcomes of fifth-grade elementary school students in IPAS on the topic of sound.
