Abstract

Previous studies have provided that when learning shapes for the first time, young children tend to use the prototype as the reference point for comparisons, but often fail when doing so since they do not yet think about the defining attributes or the geometric properties of the shapes. Most of the time, elementary students learn geometric properties of shapes only as empty verbal statements to be memorized, without any chance to experience the contepts meaningfully. In the light of it, a sequence of instructional activities along with computer manipulative was designed to support Indonesian third graders in constructing geometric properties of square, rectangle, and triangle. The aim of the present study is to develop a loval instructional theory to support third graders in constructing geometric properties of rectangle, square, and triangle. Thirty seven students of one third grade classes in SD Pupuk Sriwijaya Palembang, along with their class teacher, were involved in the study. Our findings suggest that the combination of computer and non-computer activities suppots third graders in constructing geometric properties of square, rectangle, and triangle in that it provides opportunities to the students to experience and to develop the concepts meaningfully while using their real experiences as the bases to attain a higher geometric thinking level.Key concepts: Geometric properties, rectangle, square, triangle, design research, realistic mathematics education DOI: http://dx.doi.org/10.22342/jme.4.2.414.160-171

Abstract

The present research and development project aims to develop and describe the quality of learning material consisting of lesson plans and student worksheets to facilitate students mathematical justification skills. The learning material is based on problem-based learning (PBL) approach and learning trajectory on the Cartesian Coordinate System. This project uses the ADDIE model (Analysis, Design, Development, Implementation, Evaluation). The subject of this research is 32 students in VIIIC SMPN 2 Bambang Lipuro. Based on the result of the validation assessment, the lesson plan and student worksheets are very valid. Based on the result of practicality using a student questionnaire, the learning material is practical. Based on the result of practicality using the observation sheet of learning implementation, the learning material is very practical. Based on the effectiveness assessment using the students mathematical justification skill test, 75% of students have minimum mathematical justification skills in the good category. However, based on the z-test, the learning material is not effective because zcount = 0,6172 < zα =1,654. So, the learning material is valid and practice to be implemented, but not yet effective to facilitate student’s justification skills. It was possibly due to obstacles happening during the implementation, like the implementation of PBL needs more time than it planed, and some students did not do the writing task.Keywords: learning material, PBL, learning trajectory, mathematical justification skills
