EFEKTIVITAS MEDIA POWER POINT INTERAKTIF DALAM MENINGKATKAN PRESTASI BELAJAR IPAS SISWA KELAS III SEKOLAH DASAR

Abstract

This study aims to: 1) determine the differences in students’ learning achievement

in IPAS between the use of interactive PowerPoint media and picture media among

third-grade students at SD Muhammadiyah Ambarbinangun, and 2) examine the

effectiveness of interactive PowerPoint–based learning media on the IPAS learning

achievement of third-grade students at SD Muhammadiyah Ambarbinangun. This

study employed a quantitative approach with a quasi-experimental design of the

nonequivalent control group type. The research was conducted at SD

Muhammadiyah Ambarbinangun by involving two classes, namely class III A as the

control group using picture media and class III B as the experimental group using

interactive PowerPoint media. Data were collected through pretest and posttest

using test instruments developed based on IPAS learning indicators. The data were

analyzed using descriptive statistics to identify students’ initial and final learning

achievement, followed by prerequisite analysis and a t-test to determine differences

in learning achievement between the two groups. The results of the study indicate

that: 1) there is a difference in IPAS learning achievement between students who

used interactive PowerPoint media and those who used picture media. The mean

posttest score of the experimental group was higher (80.00) than that of the control

group (67.89), with a significance value of 0.014 < 0.05; and 2) interactive

PowerPoint media are proven to be effective in improving IPAS learning

achievement, as indicated by an N-Gain score of 0.68 in the moderate category.

Therefore, the use of interactive PowerPoint media effectively improves the IPAS

learning achievement of third-grade students.
