The research aimed to see whether SAVI learning approach is better than a normal class in improving students’ critical mathematical thinking skills due to number theory lectures of mathematics. This research used a quantitative research approach with experimental method in the form of quasi-experiment. The population of this research was all the fourth semester of mathematics department students of Malikussaleh University. The sampling used was a purposive sampling that consisted of students in class A1 and A2. The research design used a non –equivalent control group design. The instrument used in this research was a set of questionnaire of critical thinking that had been validated by several validators. Then, the analysis of the improvement score of students’ critical mathematical skills used a normalized gain data which shows the improvement of students’ score classification compared to the ideal maximum score. However, the n-gain score data of students’ critical mathematical skills of control class was not normally distributed. so a non-parametric test was conducted, namely the Mann Whitney U Test. Form Test results, the Asymp. Sig. (1-tailed) value was obtined around 0.008 < α = 0,05. This shows that H0 is rejected.Hence, it means that the improvement of students’ critical mathematical skills of experimental class is significantly better than a control class. Thus, it is also proven by the hypothesis that applying SAVI approach in learning is better than a normal class without any treatment in improving students’ critical mathematical thinking skills.

The AUD study at Al Hikmah Mujahidin Kindergarten and TK Kartika XIX-3 applied a descriptive and quantitative research approach using quasi-experimental techniques. The design carried out has the consideration that, if random grouping is carried out, it will disrupt learning and programs at school. The experimental design used is the non-equivalent control group design. The purpose of the research is to find out and examine the teacher's ability to build ethnomatematic literacy at TK AL Wisdom of Mujahideen and TK Kartika XIX-3. The benefits of research are to help develop the repertoire of theories, knowledge and practices regarding the ability of teachers to develop ethnomatematic literacy. This study produced several findings related to child etnomatematics literacy. Based on the results of the study it was found that the average ethnomatematic literacy before learning did not differ significantly from the experimental-control class. That is, that before learning is carried out, the initial ability difference between the two classes is obtained. Furthermore, after the action was carried out, posttest was carried out to see the final results after being given treatment in both classes. The posttest results on ethnomatematics literacy prove that there is a greater increase in the experimental class compared to the control class. The average posttest of the experimental class is 125.43 with the percentage of achievement that is equal to 91% while for the control group the average is 105.95 with the percentage of achievement that is equal to 82%. Summary of the scores on children's ethnomatematic literacy in the control and experimental classes. The results of the study prove that the actions in the experimental class were able to improve children's ethnomatic literacy better than the control class.
