The Development of Mathematics Learning Device with Metacognitive Approach Oriented to Mathematical Literacy and Mathematical Attitude of General High School Students

This study aims to determine the development of mathematic learning device with metacognitive approach which is oriented to the ability of mathematical literacy and mathematical attitude that is valid, practical and effective. Learning device development model refers to the Plomp Model which has 3 steps: preliminary stage, development or prototyping phase and assessment phase. The subject of the research is the students of grade - VIIG SMPN 16 Yogyakarta in the second semester of academic year 2017/2018. The research data were obtained by validation sheet, teacher's assessment sheets, questionnaires of student assessment, learning enforcement observation sheet, mathematical literacy ability test, and questionnaires of students mathematical attitude. The product of this research is the lesson plans (RPP) and worksheets (LKS).The results indicate that learning device with metacognitive approach oriented to the ability of mathematical literacy and students' mathematical attitudes meet the validity based on expert validation results, practical based on teacher and student ratings, and effective requirements based on the achievement of KKM ≥75% and high category ≥75% mathematical attitude.
