Didactic trajectory of research in mathematics education using research-based learning

This study aims to describe the role of research-based learning in design a learning trajectory of research in mathematics education to enhance research and academic writing skills for pre-service mathematics teachers. The method used is a design research with three stages, namely the preliminary design, teaching experiment, and retrospective analysis. The research subjects are pre-service mathematics teacher class of 2012 from one higher education institution in Tangerang - Indonesia. The use of research-based learning in designing learning trajectory of research in mathematics education plays a crucial role as a trigger to enhancing math department preservice teachers research and academic writing skills. Also, this study also describes the design principles and characteristics of the learning trajectory namely didactic trajectory generated by the role of research-based learning syntax.

IMPROVING INTUITION SKILLS WITH REALISTIC MATHEMATICS EDUCATION

The intention of the present study was to see the improvement of students’ intuitive skills. This improvement was seen by comparing the Realistic Mathematics Education (RME)-based instruction with the conventional mathematics instruction. The subject of this study was 164 fifth graders of elementary school in Palembang. The design of this study was a Pretest-Posttest Control Group Experiment. Data was analyzed with the help of SPSS. The result of this study showed that there was different improvement of students’ skills. The improvement was higher in the class using the RME-based instruction that in conventional mathematics class.
