The Development of Mathematical Literacy on Decimals Using Simulated Situations Integrated with Gamification for Grade 7 Students

Abstract

          This research aimed to develop mathematical literacy on the topic of decimals using simulation-based learning combined with the gamification concept for Grade 7 students. The sample group consisted of 22 Grade 7 students from a school in Kalasin Province during the first semester of the 2024 academic year. The sample was selected using cluster random sampling, with classrooms as the sampling unit. The research instruments included eight lesson plans incorporating simulation-based learning and gamification, as well as a mathematical literacy test on decimals. The research followed an action research design, consisting of two action cycles. The first cycle covered lesson plans 1 to 4, while the second cycle covered lesson plans 5 to 8. Each cycle included a five-item subjective test assessing students' mathematical literacy on decimals. Data analysis was conducted using statistical methods, including mean, percentage, and standard deviation. The findings revealed that in the first cycle, students achieved an average score of 68.94%, whereas in the second cycle, their average score increased to 83.38%. This demonstrates that students’ mathematical literacy on decimals improved significantly when engaged in learning activities incorporating simulated scenarios and gamification. Moreover, the students' average mathematical literacy scores in the second cycle met the "very good" quality standard, with statistical significance at the 0.50 level.
