Abstract

Abstract. The purpose of this study is to explore ethnomatematics in the activities of cocoa farmers to create the teaching materials for students in the form of the packages of test. The type of research was qualitative research with ethnographic approaches. The data collection method used were observation and interview. The research subjects were six people. The ethnomatematics included the activity of counting, measuring, and designing. This study focused on determining the estimated number of trees based on its distance and area by using stakes (patok), determining the fertilization model based on the fertilization time and the planting age, determining the number of workers based on the land area, and estimating yields. The emerging mathematical concepts were comparison and social arithmetic. Keywords: Ethnomatematics, cocoa farmers, culture

Abstract

Abstract: The purpose of this study is to describe the profile of algebraic thinking in junior high school students in solving mathematical problems in terms of cognitive style (reflective and impulsive). The subjects used were class VIII B Arjasa 1 Junior High School as many as 25 children. Data collection in this study used two test questions, namely the MFFT test (Matching Familiar Figure Test), algebra test and interviews with four students representing different cognitive styles (reflective and impulsive) . In this study students who have reflective cognitive style and students who have impulsive cognitive style can fulfill five indicators of algebraic thinking, namely generalization, abstraction, analytical thinking, dynamic thinking, and modeling. Kata Kunci: Algebraic thinking, Reflective Cognitive Style, Impulsive Cognitive Style

Abstract

Abstract.Ethnomatematics is the practice or daily activities of a society that has become a culture and there is the application of basic mathematical concepts. The purpose of this research is to describe ethnomatematics on the activities of hatching process of semi-natural green turtle eggs in Sukamade, Meru Betiri National Park to make teaching materials for students in the form of test questions and calculate the fractal dimensions on sand used for hatching the eggs of green turtle. This type of research is qualitative research with an ethnographic approach. The data collection methods used are observation and interviews. The research subjects were the UPKP (Turtle Conservation Management Unit), MMP (Gamekeeper Partner Community) and Facilitators. This study focuses on the activities to calculate, measure, and design. The mathematical concepts that arise are arithmetic operations, value comparisons, arithmetic series and geometric shapes. Fractal dimension calculations on natural and semi-natural sand in the process of hatching green turtle eggs with MATLAB aid program obtained the fractal dimensions on natural sand was 1.7252 and on semi-natural sand was 1.7273. Keywords: Ethnomatematics, Green Turtle, Fractal Dimension

Abstract

Ethnomathematics is the study of the relationship between mathematics and culture that found in society. This research was conducted at the GESIBU Blambangan Banyuwangi gate. The purpose of this study was to describe ethnomatematics form at the Blambangan GESIBU Gate and arrange it into the research product in the form of ethnomatematic-based student worksheets (LKS). This research is a qualitative research with descriptive data analysis. There are three data collecting technique being used, those are observation, interview, and documentation The subject of this research were four people, namely cultural observers, archaeologists, builders, and carvers. The results showed that there were an ethnomatematics in the arrangement of shapes and sizes for each component of the gate from its roof, body, foot and the carving. The shape and size from each gate component contain ethnomatatics, such as two-dimensional figure, solid figure/geometry, geometric transformation (reflection, dilation, and rotation), and arithmetic sequence patterns

Abstract

Teaching approach applied by mathematics teacher can affect students' mathematical connection ability (MCA). The fact shows that there are still many teachers using conventional learning, causing passive students and low MCA among students. The purpose of this study was to describe the effectiveness of applying a collaborative realistic mathematics education (RME) approach using the classroom and the outdoor environment to improve students' MCA on the topic of similar triangles. This quasi-experimental research with a qualitative descriptive approach took the subject of ninth-grade students at a public junior high school in Jember, Indonesia. Data were collected using observation sheets, questionnaires, tests, and interviews. The data were analyzed using the effectiveness test (N-gain score). The results showed that the application of collaborative RME using the indoor and outdoor classrooms made students more active in physical, social, and mental activities. This learning is effective in improving students' MCA. The average score of 57.47 in the pre-test increased to 93.88 in the post-test, and the N-gain score was 0.86. Mathematics teachers are advised to apply this learning approach, not only on the topic of similarity triangles, but also on other suitable topics.

Abstract

Learning mathematics is frequently regarded as difficult by students, resulting in a lack of problem-solving ability. This problem occurred at SMPN 8 Jember, where, based on the results of observations, grade VII students have low problem-solving skills due to the conventional learning model used. If the problem is not addressed immediately, it is feared that it will continue with the next generation of students. This study aims to determine the effectiveness of PBL model of the peer tutor method assisted by card problems on mathematics learning outcomes in seventh-grade junior high school students with quadrilateral material. This research includes a quasi-experimental design. The data collection technique uses pretest and posttest tests to be tested with the paired samples T test and regression test (ANOVA) on the SPSS application. The results of the paired samples T test in the experimental class gave a sig value of 0.000, while in the control class it was 0.003. The sig value for the regression test for the experimental class is 0.014, while the sig value for the control class is 0.033. These results show that the PBL model of the peer tutor method assisted by card problems is more effective and influential than the PBL model of the peer tutor method to improve student mathematics learning outcomes. The study concludes that incorporating card problem learning media into the PBL model of the peer tutor method produces effective results in terms of quadrilateral material mathematics learning outcomes.
