Abstract

AbsrtactMathematics is one of the compulsory subjects taught at all levels of education. a model is neededto support students' needs to improve students' understanding of concepts. The CORE learningmodel with the Student facilitator and explaining strategy is very good in improving students'understanding of mathematical concepts. The purpose of this study was to determine theeffectiveness of the CORE model with a student facilitator and explaining strategy on students'understanding of mathematical concepts. This study uses a quantitative method with a quasiexperimental approach and a non-equivalent control group design. the author conducted a test ofvalidity, normality, homogeneity and reliability of the test to determine the correctness andsuitability of the instrument used. From the calculation results, the results of the test have a validvalue and have a normal distribution. For the homogeneity and reliability test, all items werehomogeneous. The calculation using the Crombach alpha reliability test was obtained for all itemsmore than 0.05, so all items on the test were appropriate or reliable. It is known that the results ofthe t-test analysis in the experimental class have an average value (mean) of 63.7 post-test andpre-test of 47.5, the increase in the average result is known to be 16.2 for all test results. Inaddition, from the results of the percentage of the effectiveness of the model category, the result isa value of 63.75. So, from these results the category of effectiveness of the learning model isincluded in the category of quite effective. Keywords: Effectiveness, CORE Model and Student Facilitator and Explaining Strategy, Understanding Mathematical Concepts

Abstract

Abstract : This study aims to identify and describe ethnomathematics in the traditional game of marbles in the Happy Village, Babelan District, Bekasi Regency, West Java. The research method used is ethnomathematics with the object of research being the traditional game of marbles. The data sources in this study consisted of: the research object, namely marbles games, sources, namely 3 elders, and related documents discussing marbles games. Data collection techniques are carried out through: observation, interviews, and documentation. Based on the research results obtained and data analysis, it is concluded that there are mathematical concepts in the game of marbles, namely: the concept of geometric shapes in the shape of marbles, the concept of flat geometry and trigonometry in the shape of the game area of ​​marbles, and the concept of opportunity and integer arithmetic operations in the implementation marble game..  Keywords: Ethnomatematics, Traditional Games, Marbles, Babelan Village.

Abstract

Abstract Mathematics is a subject that is quite difficult for students. Many students feel anxious when faced with math problems. The purpose of this study was to determine the level of math anxiety possessed by students based on their learning outcomes. This research is a descriptive qualitative research with 62 junior high school students representing each category of anxiety as subjects. Data collection techniques in this study include observation, questionnaires, interviews, and tests. The results of the study show that the math anxiety experienced by students in solving flat-sided geometrical problems consists of 4 levels of anxiety, namely the category of no anxiety as many as 8 students or 13%, the category of mild anxiety as many as 34 students or 55%, the category of moderate anxiety as many as 18 students or 29%, severe anxiety category as many as 2 students or 3%. Overall, students’ mathematical anxiety in solving problems on solid shapes topi was in low category with the average score of test result is 38,18 which is in opor category.   Keywords: Learning Outcome, Mathematics Anxiety

Abstract

An extension of the metric space in which the distance of the same point is not always zero is called a partial metric space. Orthogonality is the relation of two perpendicular lines at one point of intersection forming a right angle. There are several ways to define orthogonality, including Pythagorean Orthogonality, Isosceles Orthogonality, and Birkhoff-James Orthogonality. The purpose of this research is to study the consistency of the definition of orthogonality in the metric space to the partial metric space. Based on these results, it can be concluded that the partial metric space can be obtained by linear induction from a metric space. Then, in developing the definition of orthogonality to the partial metric space, it can be concluded that the qualified orthogonality is the I-orthogonality and the BJ-orthogonality, while the P-orthogonality does not qualify the consistency of the definition of orthogonality in the partial metric space. Kata Kunci: Orthogonality, Consistency, and Partial metric space

Abstract

Abstract This study aims to improve science learning outcomes for class VII A students of SMPN 3 Kasihan through the picture and picture cooperative learning model. This is because students are less active in teaching and learning activities as well as low attention to learning material. This type of research is Classroom Action Research (PTK) with the research subject of class VII A students of SMPN 3 Kasihan for the 2018/2019 academic year, a total of 32 students. The implementation of the action was carried out in 2 cycles, each cycle consisting of 2 meetings. The instruments used are observation, documentation, and test. Observation is used to observe during the teaching and learning process, documentation to collect data and student test results, as well as test methods that are carried out at the end of each cycle which are useful for knowing the increase in student learning outcomes. The data analysis technique is in the form of descriptive qualitative. This study showed an increase in student learning outcomes KI 3 (knowledge) cycle I obtained a completeness level of 37.50%, cycle 2 increased to 100%, which means there was a significant increase of 62.50%. Whereas in KI 4 (skills) in cycle 1 the level of completeness reached 59.38% while in cycle 2 it was 90.62% which means there was a significant increase of 31.24%.   Keywords: Learning Outcomes, Picture and Picture.
