Hand’s on Activity to Increase Student’s Understanding about Place Value at Elementary School
Abstract
The purpose of this research was to increase student’s understanding about place value at elementary school. This research was conducted at second grade of an elementary public school no 13 in Kecamatan Padang Barat. There were three phases of the development: preliminary research, development/prototype phase, and assessment phase. The model of development was adapted from Plomp model. This research was focused until development/prototyping and implementation. The first step was discuss with teacher to get some information about the problems in mathematics instruction at the second grade. The teacher still have the difficulty how to show the real process in addition and subtraction operation at natural number. The second step was preparing the Base Ten Blocks and creating the booklet about how to use it. In this prototyping phase the booklet was corrected by teacher and expert. This phase had micro-cycle until the teacher and the students find the booklet useful. In first prototype, validation was conducted by self-evaluation and expert review. After the revision of the first prototype, the second prototype was created, and then it was used to know about its practicality by implementation in small group evaluation and student in class.
