Abstract

The purpose of this study was to determine the effect of the Course Riview Horay (CRH) learning model assisted by the Math Riddles application on the critical thinking skills of class XI students at Al-Arifin Rahuning Private Madrasah Aliyah in the 2022/2023 academic year. This research is an experimental research with a pretest-posttest control group design. The population in this study were all students of class XI Al-Arifin Rahuning Private Madrasah Aliyah. Two classes were selected by purposive sampling to be the research sample. Class XI MIA-1 consists of 25 students as an experimental class which is taught by applying the Course Riview Horay learning model assisted by the Matt Riddles application while class XI MIA-2 consists of 25 students as a control class taught using the Expository learning model. The data obtained in this study were scores of students' critical thinking skills which were analyzed by t-test. Based on data on students' critical thinking skills that have been obtained, it is known that the average value of students' critical thinking skills in the experimental class is greater than that of the control class. From the results of the calculation of the hypothesis test , it is obtained that > >then it is rejected and accepted. Based on the results of data analysis, it was found that there was an influence of the Course Review Horay (CRH) model assisted by the Math Riddles application on the critical thinking skills of class XI MAS Al- Arifin Rahuning students.

Abstract

Students' literacy and numeracy abilities are one of the abilities that really need to be improved in order to be able to withstand the challenges of education in the 21st century. Mindset is one of the things that influences students' literacy and numeracy abilities. The aim of this research is to describe the literacy and numeracy abilities of students' mathematical thinking patterns in working on problems with comparative material. The research method uses a qualitative descriptive method which was carried out at UPTD SMP N 1 Aek Kuasan in 2023/2024 Academic Year. The sampling technique is purposive sampling. The subjects in this research are 25 VIIth -1 class students with different thought patterns. Data collection using, observation, tests, interviews and documentation. They analyzed including reducing data, presenting them, and drawing conclusions. The results of this research show that the literacy and numeracy abilities of students at UPTD SMP N 1 Aek Kuasan are categorized into 3 categories, namely high, medium, low, where the high category is 32%, and the medium is 36% and the low one is 32% and then doing such an interview sample of 3 students, to strengthen the research results.  Keywords : Literacy and Numeracy Ability; Mindset, Mathematics

Abstract

The purpose of this research is to determine the influence of the learning model. The influence of the Means Ends Analysis (MEA) learning model assisted by GeoGebra on the mathematical problem solving abilities. The research design class ‘s two group, that’s pretest-posttest design. The population in this study are Xth Class which consisted of 6 classes. The research sample consisted of 2 clases (Xth-3 class and Xth-6) which are taken by random sampling. Xth-3 Class as an experimental class using the Means Ends Analysis (MEA) learning model assited by geogebra and Xth-6 class ‘s as a control class with a direct learning model. After the learning was completed, posttest was obtained with the average score for the experimental class (80,07) and the control class (74,648). The results of the t-test obtained t_count t_table, namely 2,83 1,67, Thus, H_0 is rejected and H_1 is accepted. Based on the results of data analysis, it was found that there was an influence of the GeoGebra-assisten Means Ends Analysis (MEA) Learning Model On Studens’mathematical Problem Solving Ablility at Xth class of SMA Negeri 1 Buntu Pane.
