Abstract

This article aims to analyze the difficulties of grade VII junior high school students in solving algebraic operation problems. This type of research is descriptive qualitative. The subjects in this study were students of class VII-A at a private junior high school in West Bandung Regency. The researcher used an instrument in the form of 7 items of comprehension ability, where each question represented an indicator of mathematical understanding. The data analysis technique used in this research is the test results of algebraic operations, data reduction and drawing conclusions. Based on the data analysis, it was found that some students had difficulties in solving algebraic operation problems, including students who did not understand what concept was being asked, students still did not understand calculating addition, subtraction and algebraic multiplication operations, students did not understand how to factor, students were less careful in writing operation signs or variables and students are still wrong in defining the variable 'x' they think that 'x' is a sign of the multiplication operation. So it can be concluded that the ability to solve algebraic operation problems in class VII-A is still low and still cannot reach the expected KKM value.

Abstract

This research aims to identify learning obstacles and factors that cause learning obstacles experienced by students in learning the concept of quadratic equations. This research used a qualitative approach with the triangulation method, the subjects in this study were 23 class X students who had studied the concept of quadratic equations. The data collection technique in this research was to give a test in the form of a description question consisting of 2 questions to 23 students. Furthermore,  the researchers analyzed each student's answer and then interviewed 3 students who are considered to be able to represent other students in this research to look more deeply into the learning obstacles that students have on the concept of quadratic equations As well as conducting tests and interviews, the researchers made observations when students passed tests. The learning obstacles that the researcher found in the concept of quadratic equation were categorized into ontogenic obstacle, didactic obstacle, and epistemology obstacle. As a final result, the researchers realized: 1) students did not (fully) understand what a quadratic equation meant; 2) students met challenging to represent the problem in algebraic form; 3) students were able to overcome quadratic equations (test) in single way.
