Abstract

This research aims to develop an open ended domica-based cards in improving creative thinking ability of elementary school students on the material fractions and find out the results of its development. The development was done by using Plomp model which consists of: (1) the initial Investigation, (2) design, (3) the realization/construction, (4) the testing, evaluation, and revision, (5) implementation. The research subjects at the the testing, evaluation, and revision phase is 38 6th grade students of SDN Kenongo 1 Tulangan Sidoarjo. While in the implementation phase, the ubject is 40 6th grade students SDN Kalitengah 1 Tanggulangin Sidoarjo. Data collection techniques use creative thinking tests, observation of students' creative thinking activities, questionnaires, and documentations. The results concluded that the open ended domica-based card to enhance the creativity of elementary school students produced two sets of cards in the material of common fraction and mixed fractions, as well as a set of cards consisting of whole fractions sub material (regular, percent, and decimal fractions), each of which contains 66 cards. Domica-based card open ended trial results good quality because it has met the criteria of validity, practicality, and effectiveness to train the creativity of students in the aspect of flexibility, elaboration, and novelty.

Abstract

Penelitian ini bertujuan untuk mengidentifikasi strategi dan level pemahaman intuitif siswa sekolah dasar dalam mengukur luas jajargenjang. Jenis penelitian yang digunakan adalah studi kasus. Teknik pengambilan data dilakukan dengan cara pemberian tugas, observasi, wawancara dan dokumentasi. Teknik analisis data yang digunakan adalah reduksi data, penyajian data, dan penarikan kesimpulan/verifikasi. Penelitian ini menemukan adanya dua strategi pemahaman intuitif yang baru yaitu strategi visual-kongkrit dan pengukuran estimasi. Sementara itu, ada dua level transisi pemahaman intuitif meliputi level 2: penutupan visual kongkrit dan level 4: penutupan susunan yang dikonstruk melalui estimasi pengukuran. Level pemahaman intuitif siswa yang dikonstruksi dari jenis-jenis strategi tersebut secara bertahap dapat mencapai level pemahaman intuitif, yaitu level 0 sampai level 6. Temuan penelitian ini berimpikasi pada level pemahaman intuitif siswa dalam mengukur luas daerah yang lebih rinci dan berhirarki. Hasil penelitian ini menyarankan agar siswa dapat mencapai pemahaman relasional atau memiliki konsep pengukuran luas yang bermakna, para pendidik khususnya di tingkat sekolah dasar harus menstimulasi pembelajaran menggunakan tugas-tugas pemahaman intuitif secara bertahap dan tidak hanya dibangun melalui pengukuran luas persegipanjang. AbstractThis study aims to identify strategies and levels of intuitive understanding of elementary school students in measuring the area of a parallelogram. This type of study is a case study. Data collection techniques carried out by giving tasks, observation, interview and documentation. Data analysis techniques used are data reduction, data presentation, and drawing conclusions/verification. This study has founded two new intuitive understanding strategies namely visual-concrete and estimation measurement strategies. Meanwhile, there are two levels of intuitive understanding transitions including level 2: visual â??concrete covering and level 4: Array covering constructed by measurement estimation. The level of students' intuitive understanding constructed from these types of strategies can gradually reach the level of intuitive understanding, level 0 to level 6. The findings of this study imply the level of students' intuitive understanding in measuring the area in a more detailed and hierarchical area. The results of this study suggest that students can achieve a relational understanding or have a meaningful broad measurement concept, educators, especially at the elementary school level, must stimulate learning using intuitive understanding tasks gradually and not only be built through rectangular area measurement.
