Abstract

This study aims to determine the communication skills and self-concept of students. This study involved 11th grade from one of the Inclusion Senior High Schools in Cimahi City. Inclusive Education is a system of education that provides opportunities for all students who have abnormalities and have potential intelligence and / or special talents to participate in education or learning in an educational environment together with students in general. This research method uses descriptive qualitative. The instruments used were mathematical communication test questions. As for self-concept, the instrument used was a questionnaire with a modified Likert scale ranging from 1-4. To examine the mathematical communication skills possessed by the eleven students provided 4 as a test instrument. Based on data obtained from the results of the study, the average criteria for mathematical communication ability was 24.55% (low). As for the self concept, the classification criteria are NA> 60 (strong). This shows that there is no positive relationship between mathematical communication skills and self-concept of students

Abstract

This study aims to: 1) find out whether the Problem Based Learning approach can improve problem solving skills in students of class X PM 1 at SMK Sangkuriang 1 Cimahi. 2) knowing whether the Problem Based Learning approach can improve student learning outcomes. The class chosen in the study was the class X PM 1 of SMK Sangkuriang 1 Cimahi. The class has low achievement and the learning response is slow. The method used is Classroom action Research through 4 phases of planning, action, observation, reflection. Data retrieval uses problem solving ability tests and student activity sheets. The research results in the percentage of students' ability to solve problems increased from 48.9%, 50%, to 61.1% for the first question. While the second question, from 60%, 61.1% to 64.4%. To complete the classical there is an increase from 36.7%, 63.3%, to 73.3%. The results of the assessment of questioning observation increased starting from 56.7%, 63.3% to 75.7%, collaboration assessments ranging from 58.3%, 65.0% to 71.7%, while independence in working on questions from cycle 1 reached 80.0%, for cycle 2 it reached 100%. Referring to the results of the study, the researchers concluded that the Problem Based Learning approach can improve problem solving skills and learning outcomes in the material system of equations and linear inequalities two variables of class X PM 1 SMK Sangkuriang 1 Cimahi academic year 2018/2019
