The Development Instrument Test of PISA and Student Worksheet ( LKPD) with Shape and Space Content Using RME Approach to Improve the Mathematic Representation Ability of High School Students

Abstract

The purpose of this study was to produce Student Worksheet (Lembar Kerja Peserta Didik / LKPD) and PISA-based test instruments that were valid; practical; effective and able to improve students mathematical representation abilities. This type of research was the Tessmer model development research. The trials in this study were conducted in class X-Science 3 and X-Science 4 of SMA Negeri 1 Dolok Batu Nanggar. From the results of trial I and trial II obtained: (1) LKPD and PISA-based test instruments on the developed RME model were valid and practical; but have not met effective criteria namely: a) classical student completeness of more than 85%; b) achievement of learning objectives of more than 75% for each item; c) students who gave a positive response of more than 80%; and d) achievement of learning time was the same as regular learning time; and (2) there was an increase in the average mathematical representation ability of students in the first trial was 0.4 with moderate and in the second trial was 0.6 in the medium category.
