The Effect of RANDAI Learning Model on Students' Mathematical Communication Ability at SMA Negeri 7 Padang
Keywords:
Learning model, RANDAI, Mathematical communication skillsAbstract
The students' low mathematical communication skills are caused by a continuous learning process that is not fully student-centered. Additionally, the learning models used so far have not been optimal or varied. This research aims to determine the mathematical communication skills of class XII students at SMA Negeri 7 Padang. This research is a quasi-experimental study with a pretest-posttest control group design. The population in this study was all students of class XII science at SMA Negeri 7 Padang in the 2023/2024 academic year. The research sample consisted of students in class XII IPA 3 as the control group and XII IPA 4 as the experimental group. The sampling technique used was total sampling. The instrument used is the question sheet contained in the form of essay questions consisting of 5 questions. The results show that the mathematical communication skills of experimental class students are higher than those of the control class with an average of experimental class pretest (65.18), experimental class posttest (80.23), control class pretest (55.21) and control class posttest (67.85 ). Data analysis was carried out using the Paired Sample T-test which showed that the significance value for the sample class was <0.05, namely 0.00. So it can be concluded that there is an effect of applying the RANDAI learning model on students' mathematical communication skills in class XII SMA Negeri 7 Padang
