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

This study aims to determine whether online learning assisted with video conferencing affects students' mathematical problem solving abilities during the Covid-19 pandemic. This research is a quasi experimental research type with a quantitative approach and a nonequivalent control group design. The population in this study were all students of mathematics education at the University of Malikussaleh semester III and the sample consisted of two classes, namely the experimental class and the control class. Data collection techniques are tests of mathematical problem solving abilities that have been tested and analyzed. The data analysis technique used is using the t test with terms of normality and homogeneity. The result of the research obtained is that there is an effect of online learning assisted by video conferencing on students' mathematical problem solving abilities during the Covid-19 pandemic.

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.

Abstract

This study was intended to investigate the influence of inquiry learning approach assisted with square word media toward students’ mathematical understanding ability in learning mathematics. This study was conducted through quantitative research procedures namely quasi-experimental design. The populations were all students of class X at MAS Syamsuddhuha. The samples were 25 students of class X MIA 1 and 25 students of class X MIA 2, selected by purposive sampling. The nonequivalent posttest-only control group design was used. The data were obtained from the post-test results of the students’ mathematical understanding; they were analyzed by using SPSS 18 software. Since the data was not normal, the non-parametric Mann-Whitney test was applied. The findings of this study showed that the significant value of the test was 0,000 and it was less than 0.05 allowed the H0 rejected. It can be concluded that there was an influence of inquiry learning approach assisted by word square media on students' mathematical understanding ability, which was done in the study of trigonometry II for class X at MAS Syamsuddhuha. Hence, mathematical understanding ability is a crucial aspect in solving mathematical problems which can be measured by applying inquiry learning approach in classroom.
