Abstract

This research is motivated by students who do not understand the concept of learning mathematics and student learning completeness is still low. The aim of the research was to increase the activity and learning outcomes in the Constructed Space Construct material using the guided inquiry method. The research subjects were class IX-D students of SMP Negeri 3 Balung. Actions include the teacher's ability to design lesson plans, implementation of learning, and observation in order to determine the increase in student learning outcomes. In the pre-cycle, it was known that the average learning outcomes were 76.10 and the learning completeness only reached 68.97% with a completeness score of 75. The results showed that there was an increase in student learning outcomes after the action was taken. In the first cycle, an average score of 77.4 was obtained and the learning completeness was 75.86%. In the second cycle, an average score of 81.90 was obtained and the learning completeness reached 89.65%, which means that learning mastery had been achieved.

Abstract

This research aims to describe how the problem-solving ability of campers students in solving trigonometry problems. This study uses the problem-solving theory by Bransford & Stein that consists of five steps, namely identifying problems, defining goals, exploring possible strategies, anticipating results and acting, and looking back and learning. The technique of taking the subject in this study used purposive sampling. The research subjects were five students of IPA vocational high school. The instruments used were tests, interviews, and questionnaires. The results showed that campers students in solving trigonometry problems are pretty good. The students can fulfill four indicators of Bransford & Stein's problem-solving: (1) collect information, (2) define goals, (3) find problem-solving strategies, (4) use the correct arithmetic operations, and can find the result.

Abstract

This study aims to: (1) determine the average ability to understand mathematical concepts of students who are taught using the collaborative learning model AIR (Auditory, Intellectual, Repetition) with CRH (Course Review Horay) assisted by video learning is better than the average understanding of mathematical concepts students who are taught using conventional learning models, (2) knowing the average mathematical concept understanding ability of students who use the AIR (Auditory, Intellectual, Repetition) collaborative learning model with CRH (Course Review Horay) assisted by learning videos to achieve the Minimum Completeness Criteria (KKM). This research is a quantitative research with experimental method. The population of this study were all eighth grade students of MTs Nurul Huda Banyuputih in the even semester 2021/2022 academic year. Data collection was carried out using the test method. The data obtained were analyzed by t test and Z test. The results showed: (1) the average mathematical concept understanding ability of students who are taught using the AIR collaboration model with CRH assisted by video learning is better than the average understanding of mathematical concepts of students who are taught using the model conventional learning, (2) the proportion of students taught using the AIR collaboration model with CRH assisted learning video gets a score of more than 75%.

Abstract

In this paper, graphs are finite and connected graph. Let be a vertex coloring of a graph G where two adjacent vertices may be colored the same color. Consider the color classes . For a vertex , representation color of v is the k-vector , where . If for every two adjacent vertices u and v of G, then f is called a metric coloring of G. The minimum k for which G has a metric k-coloring is called the metric chromatic number of G and is denoted by . In this paper, we study the metric chromatic numbers of related wheel graphs namely double wheel graph, web graph, friendship graph and helm graph.

Abstract

This study aims to produce valid and practical math vlogs for set material to increase the learning interest of seventh-grade junior high school students. The development method used is the 4D model, which consists of 4 stages: define, design, develop, and disseminate. Material experts and media experts measured the validity of the vlogs, while practicality was obtained from practicality questionnaires from teachers and students. The increase in students' interest in learning was measured by an interest in learning questionnaire given before and after watching the developed mathematics vlog. The research results show that the developed math vlog meets valid, practical and effective criteria to increase students' interest in learning.

Abstract

Pewarnaan graceful merupakan kombinasi antara konsep graceful dan pewarnaan simpul. Pewarnaan graceful dilakukan dengan meminimalkan warna simpul dan sisi secara tepat. Sedangkan warna sisi diperoleh dari pewarnaan simpul yang bertetangga. Penelitian ini bertujuan untuk mengetahui pewarnaan graceful dan bilangan kromatik pada graf siklus comb graf star. Penelitian ini merupakan jenis penelitian eksploratif dengan menggunakan metode deduktif aksiomatik dan metode pendeteksi pola. Dari penelitian ini ditemukan satu teorema baru yang terdiri dari tiga kasus mengenai pewarnaan graceful pada graf siklus comb graf star.

Abstract

This study aims to determine the interest in learning mathematics of students who take part in the Two Stay Two Stray Cooperative Learning Model and whether the learning outcomes of students who take part in the Two Stay Two Stray Cooperative Learning Model are better than the results of students who take conventional learning in Class VIII MTsN 9 Padang Pariaman Academic Year 2022/2023. This type of research is pre-experimental with the research design The Static Group Comparison Design. The population in this study were all grade VIII students of MTsN 9 Padang Pariaman for the 2022/2023 academic year. The sampling was carried out randomly by first testing the normality, homogeneity and average similarity of the population data. The samples in this study were students of class VIII.2 as the experimental class and students of class VIII.3 as the control class. The results showed that students' interest in learning mathematics in class VIII MTsN 9 Padang Pariaman who took part in learning the Cooperative Type Two Stay Two Stray learning model was 76.99% with strong criteria. Students' mathematics learning outcomes were processed using the t-test at a significant level α = 0.05, the value of tcount > ttable was obtained, namely 3.42 > 1.68; whereas with Minitab Software obtained P-value <α, namely 0.001 <0.05, so that H0 was rejected and H1 was accepted. So, it can be concluded that the mathematics learning outcomes of students who take the Two Stay Two Stray Cooperative learning model are better than those who take conventional learning in class VIII MTsN 9 Padang Pariaman in the 2022/2023 Academic Year. Keyword : Interest in Learning, Learning Outcomes, Type Two Stay Two Stray Cooperative Learning Model
