Abstract

Ethnomathematics is an activity carried out by a group of cultures where they are unaware that there is a basic application or concept of mathematics in it. Learning mathematics needs an approach that is able to connect mathematics with everyday culture. One of the cultures possessed by Indonesia is batik art. Batik Sekar Jagad Blambangan is a typical batik in Banyuwangi. This research aimss to describe the results of ethnomathematics exploration of Batik Sekar Jagad Blambangan and make student teaching materials student worksheet especially for grade XI Senior High School with geometry transformation material. This study used qualitative research with an ethnographic approach. The subjects are 2 craftsmen at Godho Batik house production in Banyuwangi. Data were collected by using observation, interview, and documentation. The result of this study indicates the existence of ethnomathematics at Batik Sekar Jagad Blambangan .There are some geometry concepts or elements found, such as: points, lines, angles, 2D shapes, congruence and geometric transformations.

Abstract

In learning activities, one of the efforts that can be done to improve students' learning abilities is to support learning styles that are following the objectives so that learning can be done effectively. This research was conducted at Junior High School 1 Kalisat, located at Jl. Diponegoro 52 Kalisat, Jember. This study aims to describe the students' critical thinking processes in solving fraction problems in terms of visual, auditory and kinesthetic learning styles. Data collection techniques used consisted of learning style questionnaires, critical thinking tests, and interview method. The subjects in this study were 6 students consisting of 2 students who represented visual, auditory, and kinesthetic learning styles. Based on data analysis, the results show that students with a visual and kinesthetic learning style meet five indicators of critical thinking, namely basic clarification, basic skills, concluding, further clarification, and strategies and tactics. Students with auditory learning styles meet the four indicators of critical thinking namely basic clarification, building basic skills, further clarification, and concluding. While students with auditory learning styles are less able to meet the indicators of strategies and tactics. Keywords: Critical Thinking, Learning Styles, Fraction Problems

Abstract

Single ventricle is a heart defect in which one of the ventricle does not developed and bother the blood flow. One of the solutions is fontan surgery. The result of Fontan surgery allows the blood flowing in veins that initially lead to the heart change into the arteries. Because of these changes, there are possibility of swelling and velocity change of blood flowing. This research constructed a mathematical model of blood flowing velocity in arteries and veins due to a single ventricle heart defect that was formed from the momentum and mass equation, which was influenced by the diameter of venous vessel and blood viscosity. The analysis of the blood flow velocity in arteries and veins due to single ventricle heart defect was simulated by MATLAB and FLUENT software. The factors observed were the effect of venous diameter and blood viscosity on the velocity of blood flow in the veins. The result indicated that the greater diameter of the vein, the smaller the flow velocity in the vein. The greater blood viscosity resulted the smaller flow velocity in arteries and veins.

Abstract

Ethnomatematics is the science of mathematics practiced by a cultural group where the society has unconsciously applied the concept of mathematics. The purpose of this study is to describe ethnomatemics in the activity of making tobacco motifs and to produce test packages. This type of research is a qualitative research with an ethnographic approach. There are three subjects in this study, S1 as the maker of patterns / designs, color locking, and "nglorod", S2 as a dyeing and coloring, and S3 as the maker of batik cap. Data collection methods used are observation, interviews, and documentation. This research is focused on the tobacco making batik activity. The results of this study indicate the existence of ethnomatematics which includes activities: counting, measuring, and designing. Ethnomatematics in this study was made as a test package in the form of descriptive questions for even ninth grade students.

Abstract

This study aims to describe students' spatial-visual ability in solving PISA questions in shape and space content based on visual, auditory, and kinesthetic learning styles. This type of research used in this research is descriptive qualitative research. Subjects in the study were six students from Class X MIPA 3 SMA Negeri 2 Tanggul consisting of two students from each of the visual, auditory and kinesthetic learning styles. The data collection methods used were questionnaires, tests, and interviews. The instruments used in this study were learning style questionnaires, shape and space content PISA test questions, and interview guidelines. The results showed that the achievement of the characteristics of the sixth spatial-visual abilities of the subjects differed. Students with a visual learning style can meet the characteristics of pattern search, conceptualization, problem-solving, and imagination in full. Students with an auditory learning style can meet the characteristics of conceptualization, problem-solving, and imagination completely but are unable to meet the characteristics of pattern search. Students with kinesthetic learning styles meet the characteristics of problem solving and imagination but are unable to meet indicators on the characteristics of pattern search and conceptualization. This can be seen from the results of solving the questions given and interviews conducted on the research subjects. Keyword: Spatial-Visual Ability, PISA Questions on Shape and Space Content, Learning Style
