Abstract

This study aims to evaluate the effectiveness of integrating the Problem-Based Learning (PBL) model with an ecosystem balance simulation game in enhancing senior high school students’ critical thinking skills. A quasi-experimental method with a matching-only posttest-only control group design was employed, involving 90 purposively selected students divided into three groups. The critical thinking instrument consisted of 12 validated essay items. Data analysis included the Kolmogorov–Smirnov normality test, Levene’s homogeneity test, and ANOVA followed by the LSD post hoc test. The results indicate a significant difference among the groups (Sig. = 0.019), with post hoc analysis showing that the experimental group performed significantly better than the conventional group, but did not differ significantly from the PBL-only group. These findings suggest that integrating simulation games into the PBL framework is associated with improved critical thinking outcomes compared to conventional instruction, while yielding results comparable to PBL without simulation support. This indicates that simulation-based PBL may serve as a complementary instructional approach that supports student engagement and conceptual understanding. The study’s implications highlight the importance of integrating interactive digital media in ecology instruction to support the development of students’ 21st-century competencies.

Abstract

This study aims to analyze the influence of the Problem-Based Learning (PBL) model, assisted by the Rabbit Dynamics Population media, on students' scientific attitudes towards ecosystem materials. This study uses a quantitative approach with a quasi-experimental design (posttest-only control group design) involving three groups, namely the experimental class (PBL assisted by simulation media), the positive control class (PBL without media), and the negative control class (discovery learning). The research sample comprised 90 students from class X at SMA Negeri 1 Jatiwaras, selected through purposive sampling. The research instrument was a 23-item scientific attitude questionnaire using a Likert scale that met validity and reliability criteria (α > 0.80). Data analysis was carried out using normality and homogeneity tests, followed by one-way ANOVA, with post hoc tests. The results showed a significant difference in students' scientific attitudes between groups (Sig. < 0.05), with the experimental class having the highest average compared to the positive and negative control classes. Further tests showed that the experimental classes differed significantly from the two control classes, while there was no significant difference between the positive and negative control classes. The increase in scientific attitudes in the experimental class is evident in the indicators of critical thinking, creativity, cooperation, and perseverance. These findings show that integrating the PBL model with the Rabbit Dynamics Population simulation media effectively improves students' scientific attitudes, and it is therefore recommended as a biology learning innovation to support 21st-century skill development.
