Strengthening Buffer Solution Learning Activities with Numbered Heads Together Models Equipped with a Combined Hand Out –Augmented Reality

Abstract

Abstract This study aims to determine the comparison of the effect between the Numbered Heads Together (NHT) model equipped with Handout-AR and NHT model equipped with Microsoft PowerPoint on student learning activities on the buffer solution. The research sample was determined using the Cluster Random Sampling technique. The study data were obtained using documentation and observation techniques. The documentation technique was used to obtain data on the students’ midterm test results. The observation technique was used to obtain the data on the scores of student learning activities. The study data were analyzed using the Mann Whitney test. The results show that the application of the NHT model equipped with Handout-AR has a better effect on student learning activities on buffer solution material than the application of the NHT model equipped with Microsoft PowerPoint. These results are supported by the results of the Mann Whitney test and the average score of student learning activities from the two experimental classes. The data analysis using the Mann Whitney test produces asymp. Sig. 2-tailed value (0.000) greater than the significance level/a (0.050). The NHT/Handout-AR class has an average score of learning activities (87.6) which is greater than the NHT/Microsoft PowerPoint class (68.4).
