Abstract

This study aims to describe the mathematical literacy of field-dependent (FD) students and field-independent students (FI) in solving PISA questions on Change and Relationship content in terms of the achievement of mathematical literacy levels. The PISA issue of Change and Relationship content is related to curriculum material, namely functions and algebra. This research is a qualitative descriptive study. The subjects in this study were students of class X MIPA 6 of SMA Negeri 1 Jember with 29 students consisting of 6 field-dependent (FD) students and 23 field-independent (FI) students. The results showed that the level of mathematics dependent literacy of field-dependent students was at level 2 (66.67% or as many as 4 students) and level 5 (33.33% or as many as 2 students) and the level of mathematics literacy of independent field students was at level 2 (13 % or as many as 3 students), level 5 (69.56% or as many as 16 students) and level 6 (17.4% or as many as 4 students).

This type of research is qualitative with ethnographic approaches. The subject in this study amounted to seven people. Data Collection using observation methods, interviews, and documentation. Data collection results are analyzed descriptively. Based on the analysis of data from the observation and interviews, obtained ethnomatematics in the process of making batik in the Setingkes Kangkung. The meaning of Ethnomatematics is the concept of algebraic and geometric concepts. Algebraic concepts include counting, measuring, and masing and geometry concepts, such as point, line, angle, construction, congruation, and Geometry transformation (translation, rotation, reflection, dilation). Ethnomatematics in this study were made as student worksheets for class VII of comparative material and the XI class of geometry transformation material.

Abstract

This development research produces online interactive learning media using GeoGebra-assisted linear programming Easyclass. The purpose of this study is to describe the process and results of developing interactive online learning media using GeoGebra-assisted Easyclass linear program material. Research using the 4-D Thiagarajan model. The study was conducted at MAN 2 Jember, followed by 24 students of class XI IPA 4. The results showed a correlation value of 0.917 so that the media was declared valid with a very high category. Practicality was analyzed based on a student response questionnaire showing a percentage of 99% so that it was declared practical with excellent criteria. The effectiveness was analyzed based on the test scores of student learning outcomes after using instructional media obtained a percentage of 88% of the number of students who scored more than 75 which were categorized very well. Based on the results of data analysis, online interactive learning media using Easyclass-assisted GeoGebra linear program material meets the criteria of validity, practicality and effectiveness so that the media can be used in carrying out learning activities.

Abstract

The objective of this study was to improve students’ responsibility especially in math class with Jigsaw cooperative learning and to know the implementation of Jigsaw in math class. This study was a collaboration classroom action research. Kemmis & Mc. The Taggart model was used in this study. The subject of this study was students in eighth grade in SMP N 2 Lendah. The result of this study showed that there is an improvement in students’ responsibility in math class by using Jigsaw. Students played a role as an expert and they discussed specific topics. After that, they discussed again in a big group and shared what they got in a small group. There is 2 cycle because in the second cycle has achieved this study target. In last, there are no students who have low responsibility or below. Almost 70% of students have high responsibility and the rest have average responsibility.

Abstract

Chronic bronchitis is a disease that attacks the respiratory tract and is one of the dangerous diseases that can cause death in the world. This study builds a mathematical model of airflow velocity in the bronchi due to chronic bronchitis which is influenced by mucus thickness and initial velocity. The type of research used is simulation research to find a picture of a simple system that will be manipulated or controlled to get an effect similar to the actual situation. The mathematical model is built on the reduction of the momentum equation and the mass continuity equation which is solved using the finite volume method and the QUICK discretization technique. The volume method is used because the fluid flow studied is O2 gas which is classified as unstructured. So by using the volume method, it will be easier to discretize to determine the values ​​that will be sought in the discretization process.

Abstract

This article aims to discuss some activities that can improve the professionalism of teachers in schools. The results of a survey conducted by PGRI regarding the impact of teacher professional certification on teacher performance show that the performance of teachers who have passed certification is still unsatisfactory and the performance of certified teachers is not satisfactory. Some of the activities of teachers in schools to improve their professionalism are making learning implementation plans, implementing student-centered learning strategies, carrying out an assessment of learning outcomes, self-development, carrying out scientific publications and innovative works, using learning media, and providing examples and guidance. Through some teacher activities at the school, the assumption that the results of the PGRI survey regarding the performance of certified teachers have not been satisfactory will be refuted or incorrect.

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.
