Kamaliyah; Zulkardi; Darmawijoyo – Indonesian Mathematical Society Journal on Mathematics Education, 2013

Indonesia's involvement in the Programme for International Student Assessment (PISA) is one attempt to see how far the development of educational programs in our country compared to other countries in the world. PISA results show that Indonesia is still at the lower level. This means that the ability of Indonesian students in solving problems that…

Assiti, Saliza Safta; Zulkardi; Darmawijoyo – Indonesian Mathematical Society Journal on Mathematics Education, 2013

The intention of the present study is to know how the pupils can learn to make a group of ten to understand the idea of unitizing. The pupils were given a contextual problem "Counting the Beads" in order to promote their understanding about the idea of unitizing. The process of designing the problem was based on the 5 tenets of…

Supporting Student's Ability in Understanding Least Common Multiple (LCM) Concept Using Storytelling

Triyani, Septi; Putri, Ratu Ilma Indra; Darmawijoyo – Indonesian Mathematical Society Journal on Mathematics Education, 2012

Several researches showed that students had difficulty in understanding the concept of Least Common Multiple (LCM) in Elementary School. This underlies the researcher to design a learning of LCM using storytelling, Legend "Putri Dayang Merindu" (LPDM), which contains situational problem related to LCM. The purposes of this study are to…

Revina, Shintia; Zulkardi; Darmawijoyo; van Galen, Frans – Indonesian Mathematical Society Journal on Mathematics Education, 2011

Many prior researches found that most of students in grade five tended to have difficulty in fully grasping the concept of volume measurement because they have to build their competence in spatial structuring. The unit of volume "packing" measurement must be integrated and coordinated in three-dimension. On the other hand, it is revealed…

Meryansumayeka; Darmawijoyo; Ilma, Ratu; den Hertog, Jaap – Indonesian Mathematical Society Journal on Mathematics Education, 2011

In guiding students to construct a mathematical concept themselves, learning process should be started by a context which is suit with the concept. In this research, we focused on structured arrangement which was believed to be able to support students ages 8-9 years old developing splitting strategy in doing multiplication. This study was a…

Putra, Zetra Hainul; Darmawijoyo; Putri, Ratu Ilma Indra; den Hertog, Jaap – Indonesian Mathematical Society Journal on Mathematics Education, 2011

Knowing number facts up to 10 become crucial if we want students to solve addition and subtraction problems using more abbreviated strategies. Otherwise, students will keep counting one-by-one until they get an answer. One of important number facts is number pairs that make ten because it is an important "benchmark" that students will…
