PROFIL BERPIKIR SISWA PESERTA OLIMPIADE MATEMATIKA DALAM MENYELESAIKAN MASALAH ALJABAR
Get PDFAbstract. This study aims to describe the profile of generalization thinking, simplifying problems, and analytic thinking of mathematical olympiad students in solving algebraic problems. The research subjects were 4 mathematical olympiad students at SMPN 2 Jember. Tests and interviews are used to collect data. Based on the analysis of the data, the results of the study show that the mathematical olympiad students can solve the given problems using non-procedural methods. They prefer to use a more effective and efficient way. In process of simplifying problems, the students can represent problems into mathematical models using algebraic forms. In making mathematical models, the students use variables as a form of example. In this study, there are still students who use symbols as variables that showing those students are still at the stage of iconic thinking according to J.Bruner's learning theory. In the analytical thinking process students are able to solve problems using the methods they obtain from the results of their analysis of the given problems. In the generalization thinking process students can find and apply existing rules or patterns to solve the given problem, even though there are still students who have not received the material. They are able to solve problems using reasonal and logical thinking.

Get PDFAbstract. Learning media is a tool to deliver the materials to students during teaching and learning process. This study aims to develop e-comic learning media on linear program of two variable. The process of developing this learning media refers to the Thiagarajan model known as the 4-D model which consists of four stages, namely define, design, develop and disseminate. The results of the comic media validation included in the valid criteria with a correlation coefficient value was 0.91. Based on the trials that have been conducted in Class X-MIPA 4 MAN 1 Jember with a total of 24 students, the results of the use of instructional media including the level of practicality are categorized as good with a percentage was 91.2%. Then the effectiveness results of comic media based on cognitive, psychomoto, and affective aspects obtained effectiveness level of "Good" in all aspects. Cognitive aspects show a percentage of students who scored above the standard score was 75%. The percentage on the student observation sheet was 87% in the psychomotor aspect. The last aspect is affective with a percentage was 93.75%.

BERPIKIR KREATIF DALAM MEMECAHKAN MASALAH SUBPOKOK BAHASAN SEGITIGA DAN SEGIEMPAT BERDASARKAN ADVERSITY QUOTIENT (AQ) SISWA KELAS VII E SMP NURIS JEMBER
Get PDFAbstract. This study aim to knows the creative thinking in solving the problem of sub-topic of triangle and quadrilateral based on adversity quotient (AQ) of class VII E Junior High School at Nuris, Jember. Data collection methods used in this study are questionnaires, tests and interviews. The instruments used are the Adversity Response Profile (ARP) questionnaire, creative thinking ability test in the form of open matter of triangle and quadrilateral material and interview. Of the population of 24 students VII class E was taken as many as 3 students is students who have high AQ value (climber), students who have AQ value being (camper), and students who have low AQ (quitter). That the climber students in the research more precisely have the creative level according to the transition category from camper to climber, camper students in this study according to the camper student category, but in this research quitter students exceed the category of quitter students, more precisely quitter students in research creative according to the transition category from quitter.

ETNOMATEMATIKA PADA AKTIVITAS PASCA PANEN TEMBAKAU MASYARAKAT PENDALUNGAN DAN PENERAPANNYA SEBAGAI LEMBAR KERJA PESERTA DIDIK
Get PDFEthnomatematics is a science that connects mathematics with culture in society. The purpose of this research was to describe the results of ethnomatematic exploration of post-harvest activities of tobacco farmers in the Pendalungan community and to make their products in the form of student worksheets. This type of research is qualitative with an ethnographic approach. Data collection methods used are observation and interviews. Ethnomatematics in tobacco post-harvest activities in the form of counting, measuring and designing activities. In the process of nyujen (submission) of tobacco leaves arises the mathematical concept of comparable values ​​and measurements when determining the length of the rope, determining the length of the bamboo, and determining the distance between leaves. In the process of making patterns of drying tobacco leaves, the concept of design and concept of comparable value emerged. In the fermentation process, tobacco leaves were observed in the concept of calculating when determining the length of fermentation time, and in the process of sorting tobacco leaves it was observed the concept of the ratio of turning value when determining the number of leaves per class in 1 kg. The results of the study are product teaching materials in the form of student worksheets. Student worksheets are intended for seventh grade Middle School / MTs students. This student worksheet is divided into 5 activities in the scientific approach.

ANALISIS PEMAHAMAN SISWA BERDASARKAN TEORI APOS MATERI BALOK DAN KUBUS DITINJAU DARI KECERDASAN EMOSIONAL
Get PDFAbstract. This research aims to describe students’ comprehension based on apos theory on the theme “cuboid and cube†from the perspective of emotional quotient of grade IX A students SMP Negeri 1 Semboro. This research is a descriptive study with qualitative approach. APOS theory assumes that understand of mathematical concept is a result of construction or reconstruction of mathematical object. Construction or reconstruction is done by action, processes, and object that are coordination in a scheme to solve the problems. So, we can know comprehension student of mathematical concept can use APOS theory. Subjects of this study were 6 students consist of 2 students with high emotional quotient, 2 students with moderate emotional quotient and 2 students with low emotional quotient. Data collection obtained with emotional quotient questionnaires, test, and interview. Based on the results of the analysis, the results can be obtained that students with high emotional quotient has reached the stage of action, process, object, and scheme; the comprehension of students with moderate emotional quotient has reached the stage of action, process, and object; the comprehension of students with low emotional quotient just has reached the stage of action, has not reached the process, object, and scheme.
