Abstract

The absence of interactive multimedia in learning hinders the achievement of learning objectives. This study aims to analyze the effectiveness of interactive multimedia based on problem-based learning in IPAS lessons for fourth-grade elementary school students. This is a development research study using the ADDIE model (Analyze, Design, Development, Implementation, Evaluation). The research subjects included experts in instructional design, content, and media, as well as 27 fourth-grade students. Data were collected using questionnaires and tests, and analyzed through descriptive quantitative methods and inferential statistics using a dependent sample t-test. The evaluation results showed that (1) the instructional design scored 92.5% (very good); (2) the feasibility of the interactive multimedia was rated highly feasible by the content expert (92.5%), instructional design expert (95%), media expert (92.5%), individual trial (95%), and small group trial (94.44%); and (3) the effectiveness of the multimedia, based on the dependent sample t-test, yielded a t-value of 9.864 with df = 26 and a significance level of 5% = 1.706, indicating tvalue > ttable, so H0 was rejected and H1 was accepted. Based on these results, it can be concluded that the PBL-based interactive multimedia is both feasible and effective for use in fourth-grade elementary school. The implication of this research is its potential to enhance students’ learning motivation, improve their understanding of the material, and encourage teachers to use innovative learning media to optimally achieve educational goals.

Abstract

Implementation of the mathematics learning process using conventional book teaching materials provided by the government and teachers who do not have enough time to develop teaching materials will affect students' learning creativity and students' understanding of mathematics material. The conventional learning process results in the formation of abstract concepts so that students' creativity in identifying and solving problems is less than optimal. The aim of the research is to develop an e-module for interactive material on the circumference and area of flat figures based on Balinese ethnomathematics that is valid, practical and effective to increase the creativity of fifth grade elementary school students. The research was conducted using the ADDIE (Analyze, Design, Development, Implementation, Evaluation) model. The subjects of this research were learning materials experts, learning media experts, 2 practitioners/class teachers and 23 students in class VB SD No. 1 Strait. The research results show that (1) the validity of learning material experts is worth 4.75 with very good qualifications, (2) the validity results of learning media experts are worth 4.35 with very good qualifications, (3) the percentage of practicality based on teacher responses is worth 98% and student responses are worth 92.6% with very good qualifications, (4) The t-test results show the significance value in the t-test is 0.000 or p < 0.05, so H0 is helpful and H1 is accepted.
