The Influence of Research-Based Learning Implementation In Improving Students’ Combinatorial Thinking Skills in Solving Local Irregularity Vertex R-Dynamic Coloring

Abstract

This research is one of the studies aimed at applying research-based learning and aims to determine its effect on the combinatorial thinking skills of students in solving local irregularity vertex r-dynamic coloring problem. The research method used in this research is mix-method. Mix-method research is a combination of qualitative research and quantitative research. The qualitative method is used to obtain data related to the results of testing on each indicator and the results of the portrait phase while the quantitative method is used for statistical analysis. The experimental class consisted of 41 respondents and the control class consisted of 30 respondents. The treatment given is different, namely between the treatment in the experimental class and the treatment in the control class. In the experimental class applied learning tools that have been developed and applied research-based learning methods. While the control class used research-based learning methods without the learning tools that have been developed. Based on the treatment that has been given, the results of students’ combinatorial thinking skills show for the control class 53% are categorized as low-level, 37% are categorized as a medium level, and 10% are categorized as a high level of combinatorial thinking skills and then experimental class that 34% are categorized as low level, 44% are categorized as a medium level, and 22% are categorized as combinatorial high-level thinking skills. The results of this study of homogeneity of two classes by using a pre-test score of 0,701 result show sig> 0.05 Thus Spake the differences of the mean of two classes is not significant. The inferential statistical result of the independent sample t-test on the posttest results Showed that the sig 2-tailed value was 0.000 ( 0.05) so that was significant. The conclusion is there is a significant impact of the application of research-based learning in improving the students’ combinatorial thinking skills in solving local irregularity vertex r-dynamic coloring.
