Abstract

Fraction is one of the topics that is learned by students from primary, in secondary school and even college. When learning about fractions, sometimes students find difficulties that can trigger errors and misconceptions. This study was conducted to identify common students’ errors and misconceptions about operations of fractions (i.e. addition, subtraction, multiplication, and division) in an Indonesian primary school. The study used a qualitative methodology and involved 4 participants (S1, S2, S3, and S4) from 6th grade students from a classroom in a public primary school in South Jakarta. They were selected based on theirscores on a test on operations of fraction (15 problems). The four participants who were chosen, each got 2, 4, 6, and 14 answers correct. The result of this study indicated that for these four students, some errors about fractions in their primary school were errors in computing the fractions and mistyping the solutions. Some of the misconceptions of fractions were related to fraction operations.

Abstract

The study's objective is to investigate common difficulties experienced by 8th-grade students when solving non-routine mathematics problems. This study used a qualitative descriptive method, and the research participants were eighth-graders students at one of the private middle schools in Jakarta. The researchers used a convenience sample to obtain a group of six students available for an in-depth interview session and willing to solve two non-routine problems related to algebra topic. The study showed that the participants experienced difficulties when solving non-routine mathematics problems. They could not read the problem comprehensively; they had trouble converting the word problems into mathematical sentences. They also had difficulty in carrying out their plans. In other words, students did not have the strategy to solve the problem. They had errors in the calculation and had incorrect formulations when solving the given problems. It is suggested that the teacher provide students with guiding instructions to assist students in going through the problem-solving phases step by step. The teacher can also highlight the non-routine problem's keywords and give a representation that helps students understand the problem. Keywords: learning difficulties, middle school students, mathematics problems DOI: http://dx.doi.org/10.23960/jpmipa/v23i1.pp67-77
