TY - JOUR JF - Proceeding of International Conference On Research, Implementation And Education Of Mathematics And Sciences 2015 (ICRIEMS 2015), Yogyakarta State University, 17-19 May 2015 SN - 978-979-96880-8-8 ID - UNY23017 UR - http://fmipa.uny.ac.id AV - public N2 - The ability of mathematical connection gets less teacher?s attention, especially in elementary school. But mathematical connection ability is a math skill must be had by students well. The purpose of the research is to test the superiority learning based on Van Hiele theory to improve student?s mathematical connection ability. Location of the research is SDN 1 Cibatuireng Karangnunggal district, Tasikmlaya regency. The method used is pre-experiment by collecting data technique those are test and non test. The results of the test are : 1). Increasing the student?s mathematic connection ability; 2) the implementation learning based on Van Hiele theory through some stages (information, direct orientation, explanation, free orientation, integration); 3) the student?s mathematical connection ability increased after using learning based on Van Hiele theory. Key words: mathematical connection, learning based on Van Hiele theory Y1 - 2015/// PB - Faculty of Mathematics and Sciences Yogyakarta State University A1 - Tiara, Penta Yurlita A1 - Epon, Nur?aeni A1 - Oyon, Haki Pranata TI - THE ENHANCEMENT ABILITY OF MATHEMATICAL CONNECTION IN PARALELLOGRAM MATERIAL THROUGH LEARNING BASED ON VAN HIELE THEORY IN CLASS V SDN 1 CIBATUIRENG ER -
