The Analysis of Students’ Learning Obstacles on the Fraction Addition Material for Five Graders of Elementary Schools

Abstract

Various researchs have explained the students' difficulties in understanding fractions, so the researcher will analyze the student obstacle learning on fraction addition material. The approach used in this research is qualitative with the case study method. The subjects in this study were 5 th grade students of Geger Kalong Girang 1-2 elementary school, Bandung City with a total of 29 students. Collecting data in this study using tests, interviews, and documentation. Data analysis uses data reduction, data display, and conclusion drawing/verification. The results of this study found that students experience 1) ontogenic obstacle caused by the students inablity to understand the picture presented so that they are not able to determine the amount of fractions; 2) epistemological obstacle caused by the inability of students to understand fractions as part of the whole and apply the wrong concept in operating fractions; and 3) didactical obstacle caused by informal teaching methods and presentation of teaching materials that did not pay attention to student involvement. This research can facilitates students in understanding fraction addition material and provides an overview to the teacher in making teaching materials and learning design about fraction addition based on learning obstacle.

Improving Student’s Learning Liveliness of Natural Science by Giving Question and Getting Answer Startegy at Islamic Elementary School

“…By interpretation, each student both individual and group is required to participate actively, ask each other questions, and can reveal idea and problem solving correctly. In this case, teacher's creativity to facilitate students' liveliness is needed, as according to (Fauzi & Suryadi, 2020) "The teacher has an important role to facilitate the students in building their knowledge and experience that guides them to achieve the expected learning goals". The teacher must be able to create a learning situation where students will ask, answer, and express idea actively in learning process (Sinar, 2018: 6).…”

The Analysis of Primary Students’ Learning Obstacles on Plane Figures’ Perimeter and Area using Onto-Semiotic Approach

“…The activity of asking questions directly without the completion procedure does not form an active learning environment. Students become passive because they only imitate the examples provided (Fauzi & Suryadi, 2020). The teacher plays a critical role in establishing a didactic conducive environment to learning.…”

“…So, it is related to cognitive maturity and mental readiness. Didactic is an obstacle to the teachers' teaching (Fauzi & Suryadi, 2020;Rachma & Rosjanuardi, 2021).…”

Learning Designs for the Addition and Subtraction of Two-Digit Numbers based on Realistic Mathematics Education Principles Using Snakes and Ladders Game

“…Numbers are topics within the domain of arithmetic. Numbers are important in learning mathematics in elementary schools (Fauzi & Suryadi, 2020;Pitta-Pantazi, 2014;Jordan et al, 2010). According to Verschaffel et al (2007), numbers are important to learn because it relates to the students' real life, serves as a basis for understanding other materials, becomes one of the first materials taught in formal schools.…”
