THE IMPACT OF UTILIZING HANDMADE INSTRUCTIONAL MEDIA COMBINED WITH QUESTION–BASED–LEARNING IN THE CONTEXT OF DECIMALS ON ACADEMIC ACHIEVEMENT AND SATISFACTION OF SEVENTH-GRADE STUDENTS

Abstract

The objectives of this research were to 1) develop handmade instructional media in mathematics for seventh-grade students, specifically focusing on the topic of decimals, aiming to meet the effectiveness criterion of 80/80, 2) compare the learning outcomes of seventh-grade students between traditional learning classes and those using handmade instructional media combined with question-based learning in the context of decimals, and 3) assess the satisfaction levels of seventh-grade students using handmade instructional media combined with question-based learning. The sample group used in the research consisted of seventh-grade students during the academic year 2023, totaling 160 students, selected through cluster random sampling, divided into an experimental group of 80 students and a control group of 80 students. Research tools included handmade instructional media 8topics, learning management plans using handmade instructional media combined with question-based learning 10 plans, normal learning management plans 10 plans, an achievement test, and a satisfaction assessment tool. Data analysis employed statistical measures such as mean, percentage, standard deviation, and an independent t-test for hypothesis testing.

The results indicated 1) The effectiveness of the handmade instructional media in mathematics on the topic of decimals at 83.33/81.72, 2) the students using the handmade instructional media combined with Question-Based-Learning exhibited higher learning achievement scores compared to those in traditional learning classes, with significance at the .05 level. Moreover, and 3) the satisfaction level of seventh-grade students with the handmade instructional media combined with Question-Based-Learning was notably high ( = 4.80, SD = 0.25).
