The analysis of research based learning implementation in improving students conjecturing skills in solving local antimagic vertex dynamic coloring

This study aims to determine the application of research based learning in improving student conjecturing skills in solving local antimagic vertex dynamic coloring problems. The research method used in this study can be regarded as a combination of qualitative and quantitative methods. Qualitative methods are used to obtain data related to test results on each indicator and the results of phase portraits while quantitative methods are used to statistical analysis. Experiment and control classes each consists of 41 and 43 responden. Both classes were given different treatments. In the experimental and control class applied research based learning methods and the experiment class will use student worksheet. Result the students conjecturing skills indicates for control class that 21% is categorized as low level, 29% is categorized as fair level, 27% is categorized as high level and 23% is categorized as very high conjecturing skill and than experiment class that 13% is categorized as low level, 24% is categorized as fair level, 36% is categorized as high level and 27% is categorized as very high conjecturing skill. The results of this study of homegenity of two clasess by using a pretest result show sig score 0.681 > 0.05 thus the differences of mean of two clasess is not significant. The inferential statistical result of the independant sample t-test on the posttest results showed that the sig(2-tailed) value was 0.007 (p ≤ 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 conjecturing skills on solving local antimagic vertex dynamic coloring.
