Winarti, Destina Wahyu; Amin, Siti Maghfirotun; Lukito, Agung; Van Gallen, Frans – Indonesian Mathematical Society Journal on Mathematics Education, 2012
Learning the concept of perimeter and area is not easy for students in grade 3 of primary school. A common mistake is that students think that if the area is the same, the perimeter also has to be the same. It is difficult for them to understand that for a given area, there are many possibilities of perimeter and vice versa. When student are not…

Shanty, Nenden Octavarulia; Wijaya, Surya – Indonesian Mathematical Society Journal on Mathematics Education, 2012
We examine how rectangular array model can support students' spatial structuring in learning multiplication. To begin, we define what we mean by spatial structuring as the mental operation of constructing an organization or form for an object or set of objects. For that reason, the eggs problem was chosen as the starting point in which the…

Khairunnisak, Cut; Maghfirotun, Siti; Juniati, Amin Dwi; de Haan, Dede – Indonesian Mathematical Society Journal on Mathematics Education, 2012
The meaning of fractions with integer multiplication is something that is difficult to understand by students. They tend to think that the product it produces a larger number, while the multiplication of fractions with integers, the result can be any number larger or smaller. This study is a research design that aims to develop a local…

Shanty, Nenden Octavarulia; Hartono, Yusuf; Putri, Ratu Ilma Indra; de Haan, Dede – Indonesian Mathematical Society Journal on Mathematics Education, 2011
This study aimed at investigating the progress of students' learning on multiplication fractions with natural numbers through the five activity levels based on Realistic Mathematics Education (RME) approach proposed by Streefland. Design research was chosen to achieve this research goal. In design research, the Hypothetical Learning Trajectory…
