Abstract

ABSTRACTThis study aims to investigate the ability of self-efficacy and improvement of students' mathematical problem-solving ability through learning by using Problem Based Learning (PBL) methods. This study uses quasi experimental methods with final test control design for mathematical self-efficacy and pre-test post-test for mathematical problem-solving ability in terms of students' early math skills. The sample of this research is the students of class X IPA in SMA 3 and SMA 4 Kabupaten Tanggerang in odd semester of academic year 2017/2018 as many as 96 students. The result of this researh are (1) There is an improvement of mathematical problem-solving ability of students who are treated with PBL methods is better than students who get conventional learning; (2) There is an interaction between learning method and early math ability (KAM) to improving students mathematical problem-solving ability; (3) There is an improvement of mathematical problem-solving ability in students with high KAM; (4) There is no improvement of mathematical problem-solving ability in students with low KAM; (5) Self-efficacy of students who are treated with PBL methods is better than students who get conventional learning; (6) There is an interaction between learning method and early math ability (KAM) to self-efficacy of students; (7) There is different self-efficacy in students with high KAM; (8) There is no different of self-efficacy in students with low KAM.Keywords: Problem Based Learning, Problem-Solving Ability, Self-Efficacy

Abstract

ABSTRACTThe study aims to see the effect of CORE instruction methods toward mathematical critical thinking  ability and mathematical dispositions of high school students in East Jakarta. Samples of this research is 88 students 11th grade Science Major from SMA Negeri Jakarta Timur. Research methods is quasi experiment using treatment by level  design. Data collection were using instruments of test and questionnarie test: mathematics prior knowledge and mathematical critical thinking ability test, and mathematical dispositions questionnaire test. Data analaysis is using two way ANOVA. Results indicated that: (1) Mathematical critical thinking ability and mathematical dispositions of students treated by CORE instruction is higher than students treated by Direct Instruction, (2) There is an interaction between learning models and mathematics prior knowledge (KAM) that have significant effect toward mathematical critical thinking ability and students mathematical dispositions, (3) Mathematical critical thinking ability and mathematical dispositions of students with high KAM treated by CORE instruction is higher than students with high KAM treated by Direct Instruction, (4) There is no significant effect of learning models toward mathematical critical thinking ability and mathematical dispositions of students with low KAM.Keywords: CORE Instruction, Mathematical Critical Thinking Ability, Mathematical Dispositions, Mathematics Prior Knowledge
