Abstract

Coronary heart disease is a disease caused by accumulation of cholesterol that forms plaques on artery walls for a considerable period of time. Over time, this disease can cause the heart muscle to weaken, and cause complications such as heart failure. One of ways to treat coronary heart disease is the stent installation (rings) or commonly called angioplasty. Angioplasty aims to make the blood vessels narrow to open so that blood flow flows better. The emergence of mathematical modeling as a new science is one alternative to solve these problems. With mathematical modeling, practitioners can make a form of a formula that describes the state of blood flow in the coronary arteries according to actual conditions without ignoring important factors in the system. In this study a mathematical model was built based on the above problems to determine the effectiveness of stent installation or angioplasty in the process that occurs in coronary arteries. Keywords: Coronary heart disease, Mathematical modeling, Stent

Abstract

High order thinking skill is the ability to complete the tasks where there is no algorithm that have been taught, that need justification or explanation and probably have more than one solution probability. High thinking skill ability is the ability that consists of analysis, evaluation and creation. Emotional intelligence is the individual intelligence in recognizing self-emotion, motivate yourself, control others emotion and foster relationships with others. Lesson study learning community is the collaborative learning from Japan. The aim of this research is to describe the process of student’s high order thinking skill in solving probability problem on LSLC based learning on emotional intelligence. The subject of this research started from giving emotional intelligence questionnaire, next the learning activity based on LSLC where the students work collaboratively on high order thinking questions on the students’ worksheet that consists of 3 questions covering question number 1 is question of analyzing, question number 2 is question of evaluating and question number 3 is question of creating, it was obtained the subject of 1 student with low emotional intelligence, 1 student with moderate emotional intelligence and 1 student with high emotional intelligence. From those three subjects, it was obtained 1 student with high emotional intelligence that has high order thinking skill, while 1 student with moderate emotional intelligence and 1 student with low emotional intellegence that did not have high order thinking skill.

Abstract

This study aims to determine the student combinatorial thinking process in solving SPLTV problems. The research subjects were 5 auditory students in class X BIC 1 MAN 1 Jember. Data collection methods used are tests and interviews. Based on data analysis, the results of the study indicate that auditory students are able to use the concept and competence to provide combinatorial reasoning. At the stage of investigation the case students able to explain information, at the stage of calculating all cases, being able to write information using symbols but not being able to write down what was asked about the problem using symbols. At the systematic stage of generating a case, being able to make a plan so as to find a solution. At the stage of changing the problem into other combinatorial, able to find solutions more than one method or more than one method but there are students who have not been able to find solutions more than one method or more than one method, able to describe the reason or cause of the solution obtained. Keywords: Combinatorial thinking, SPLTV, Auditory learning style.

Abstract

This study aims to describe the profile of problem solving students based on the Polya stages in terms of cognitive style. The problem solving profile is a general description or description of the activities of solving mathematical problems carried out by students using previously acquired knowledge. The description is related to the psychological cognitive style possessed by students. Psychological cognitive style is divided into 2, namely the independent and field dependent cognitive style fields. Analysis of students' answers in the problem of the Two Variable Linear Equation System based on the 4 stages of the Polya consists of understanding the problem, making a plan of completion, implementing the completion plan and checking again. The instruments used were GEFT test, problem solving test, Two Variable Linear Equation System, and interview. The subjects of the study were 6 VIIIE class students at Genteng 2 Public Middle School. In general, field independent students are better at solving problems than field dependent students. Keywords: Cognitive Style, Problem Solving, Polya Stage, Profile.

Abstract

This study aims to describe the mathematical communication skills of junior high school students who experience deficiencies in reading writing, and counting (calistung). Mathematical communication ability consists of mathematical communication skills in verbal and in writing. The subjects of this study were 4 students in the calistung class. The method of data collection is through tests, interviews, and observations. Based on the results of the analysis, the mathematical communication skills of the calistung participants (reading, writing and counting) were in the range of the lowest three levels. Student 1 (S1) is at level 2 which is good enough. Student 2 (S2) mathematical communication skills are at level 2 which is quite good. Student 3 (S3) mathematical communication skills are at level 2 which is quite good. The mathematical communication ability of Student 4 (S4) is at level 1 which can be said to be of poor ability because it only fulfills 9 indicators out of all 32 indicators. Keywords: communication skills, mathematical communication skills, mathematical problem solving.
