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.

Abstract

The purpose of this study was to determine the mathematical critical thinking ability of students who were taught using the Auditory Intellectually Repetition learning model was better than the mathematical critical thinking skills of students who were taught through a scientific learning approach. This study uses a quantitative approach and the type of research used is quasi-experimental research. The population in this study were 11th grade students of SMA Negeri 5 Simeulue Barat, the samples in this study were two classes selected using a nonprobability sampling technique of purposive sampling type, namely class 11 IPA-1 as an experimental class using the Auditory Intellectually Repetition model and class 11 IPA-2 as a control class using a scientific approach. The data processing technique uses SPSS version 25 with the results of the study showing that: the value of Sig (p-value) > 0.05), it is accepted that it is 0.629 in the experimental class and 0.273 in the control class so that the data has a normal distribution. The t-test analysis of students' mathematical critical thinking skills was obtained 0.001 < 0.05, then Ho was rejected and Ha was accepted. This means that the mathematical critical thinking ability of students who are taught with the Auditory Intellectually Repetition learning model is better than the mathematical critical thinking skills of students who are taught with a scientific learning approach.

Abstract

The purpose of this development research is to determine the feasibility and effectiveness of using Powtoon animation learning media for flat-sided geometry. The development model used is the ADDIE model. The subjects of this study were students of class VIII-2 MTsS Syamsuddhuha (junior high religious school). The percentage results of product assessment by media experts are 96% in the very feasible category, the percentage result of product assessment by material experts is 92% in the very feasible category, and the percentage result of product assessment by 10 small group students is 94% in the very feasible category. Based on the results of the product assessment by all validators who stated that it was very feasible, the Powtoon animation learning media developed had meet the criteria for use for students. The effectiveness of using the product can be seen from the results of the comparison of the students' average pretest and posttest scores. The resulting product is effective in increasing the understanding of mathematical concepts, as evidenced by the average pretest score of 43,44, an increase in the posttest of 84,27, and the N-Gain value of 0,72 in the high category. It can be concluded that Powtoon animation learning media is feasible and effective to be used in improving the understanding of mathematical concepts.
