Design and validation of learning sequences of PGSD Sanata Dharma University student to teach the fraction concept for primary student using Montessori manipulatives

Abstract

Fraction concept is one of the learning problems that often occurs in elementary students. Elementary student’s misconceptions can be caused by teacher’s misconceptions. PGSD students are teacher candidates, so they must have the correct concept then they can teach the concept of fractions correctly too. Learning must be an inspiration for students when they become teachers later. One medium that can be used to teach fraction concepts is media based on Montessori. Local culture can support the use of Montessori media. This study aims to design and validate the learning sequence of PGSD Students in using Montessori media, to develop design principles to teach fraction concepts in elementary school students. The approach in this research is design research which includes three phases, namely design, trial and assessment. In the design phase, researchers formulate students’ prior knowledge and learning objectives. This is used as the basis for the sequence of learning. This stage of learning is evaluated in a repeat trial phases, the hypothesis design principle is developed and from which the learning stages are redesigned. The results of the assessment phase, together with the experience of the previous cycle and research review, are used to perfect the design principles of the student’s learning sequences so they can teach the concept of fractions correctly.
