Abstract

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.

Abstract

Mathematics is a discipline that is taught at every level of education in Indonesia. Mathematics are interrelated with each other, and cannot be separated from other disciplines and problems in everyday life. Process standards that students use in learning mathematics include problem solving, reasoning and proof, connection, communication, and representation. This study aims to determine the mathematical connection ability of students who are taught through the make a match cooperative learning model better than the students' mathematical connection ability through the scientific learning model on the line and row material in class XI SMAN 1 Pintu Rime Gayo. This research is a quasi-experimental study using the pretest-posttest group design. The samples taken were class XI MIA 2 as the experimental class and XI MIA 1 as the control class. Retrieval of data in research using tests. The data collected from the test results were analyzed using SPSS version 18 to find normality using the Shapiro-Wilk test and to test the hypothesis using the Mann-Whitney-Test. Based on the results of data analysis, it shows that the N-gain average score of students who apply the make a match cooperative learning model is 0.71 (high category), higher than students who use scientific learning of 0.36 (moderate category). From the results of the Mann-Whitney-Test above, the Asymp value is obtained. Sig (1-tailed) is 0.0005 <α 0.05. This shows that the increase in students' mathematical connection ability through cooperative learning type make a match is significantly better than students who get scientific learning.

Abstract

Students' mathematical communication is stated to be low because students learn by listening and seeing the teacher solve mathematical problems and students have difficulty in expressing everyday events in mathematical models. This study aims to determine whether there is an influence of the Inside Outside Circle (IOC) type of cooperative learning model on students' mathematical communication skills better than using scientific learning. This study uses a quantitative approach with the type of research Quasi-Experimental Design and the design of this research The Nonequivalent Postets-Only Control Group Design. The population in this study were all students of class VIII SMP Negeri 1 Nisam, while the samples were class VIIIB as the experimental class and class VIII-A as the control class with the sampling technique of purposive sampling. The data collection technique in this study used a mathematical communication ability test. The data analysis was carried out for the mathematical communication ability test using the t-test because the data were normally distributed and homogeneous, the data were processed using SPSS 18 software and the hypothesis test results were obtained with a significant value of 0.000 less than 0.05, which means reject H0 and accept Ha. The results showed that there was an effect of the Inside-Outside Circle (IOC) type of cooperative learning model on students' mathematical communication skills.
