Abstract

This study aims to analyze the mathematical concept understanding ability of seventh grade students at SMP Swasta Bhayangkari 3 Rantauprapat regarding the topic of two-dimensional quadrilaterals. The assessment of concept understanding focuses on determining the extent of students' abilities in solving problems related to mathematical concepts, using the following indicators: Understanding mathematical concepts includes the ability to define a concept both verbally and in writing, group objects based on certain properties, provide examples and counter-examples of a concept, present the concept in various forms of representation, and apply concepts or algorithms to solve problems. The research method used is descriptive qualitative, involving 24 students as research subjects. Data were collected through a concept understanding test consisting of 5 questions related to two-dimensional quadrilaterals. The results indicate that 8 students, or 33.3%, are categorized as having high understanding, 12 students, or 50%, are in the moderate category, and 4 students, or 16.6%, fall into the low category. Thus, the mathematical concept understanding ability of the students is considered to be quite good. The research results show that students' understanding of mathematical concepts still needs to be improved, especially in the ability to explain concepts, clarify the nature of objects, and present concepts in various representations.

Abstract

This study aims to determine whether there is an effect of YouTube on student learning activeness and performance in class VIII MTS Tarbiyah Islamiyah Ulumahuam students. This activity was carried out offline. The research subjects were MTS Tarbiyah Islamiyah Ulumahuam students and the sample used amounted to 50 students where 25 participants for the experimental class and 25 participants for the control class. The instrument used is a questionnaire of student activeness and learning performance using YouTube as media and documentation. The analysis techniques used are Normality, Homogeneity, and Hypothesis tests. Based on the results of the research conducted, there is an effect of YouTube on the activeness and performance of student learning with a learning model using YouTube seen from the average value of the questionnaire of student learning activeness and performance, namely with a significant value of 0.000. For hypothesis testing using one-way anova test with significant results of 0.000

Abstract

This ponder points to analyze the impact of the jigsaw sort agreeable learning show on students' basic considering abilities, and see how colossal and positive or negative the impact that happens between the two factors. This investigate employments a quantitative approach strategy of genuine test sort. by utilizing the Pretest-Posttest Control Gather Plan investigate plan. The populace of this think about was all lesson VIII MTs Tarbiyah Islamiyah comprising of 2 classes totaling 55 understudies. The test utilized was lesson VIII-b as numerous as 30 understudies. the testing procedure utilized was arbitrary testing strategy. Information were collected through test questions on SPLDV fabric a few time as of late and after treatment of the jigsaw learning show. The information were analyzed utilizing parametric truthful tests, to be particular essential straight relapse tests with SPSS 22.0 The comes approximately of the examination appeared that the Sig.2 (2-tailed) esteem was 0.040 and 0.040 < 0.05, meaning that there was a noteworthy impact between variable X and variable Y, to be particular the impact of the jigsaw learning show on students' basic considering capacities.

Abstract

Full-day school not only serves as a system for fostering excellent concentration and understanding in children's learning, but also hones their ability to think relevantly and adds enthusiasm to their pursuit of knowledge. This study aims to determine the significant impact of full-day school on students' concentration and understanding of mathematics. The research method used was qualitative, utilizing data analysis such as validation tests, linearity tests, homogeneity tests, and T-tests. The results showed that full-day school had a significant impact, particularly on students' concentration. Initially, students were stable in their learning, but over time, their concentration weakened due to fatigue from prolonged study. This can also impact students' understanding of mathematics. In this study, the effect of full-day school on concentration and understanding of mathematics was 0.464> 0.05 and the calculated t value was 4.303> t table. It can be concluded that Ha is accepted which means there is an effect of full-day school (x) on concentration and understanding of mathematics (y). So from the explanation, it can be seen that the calculated t is greater than the t table, meaning Ho is rejected. There is a significant influence between full day school on concentration and understanding of mathematics in SMA Swasta HAS SEPAKAT.
