Abstract

This research is a case study research that aims to find out the difficulties of junior high school students in solving SPLDV problems. The subjects in this study were 10 students of class VIII-B MTs Negeri 3 Purwakarta, consisting of 3 students who had low abilities, 4 students who had moderate abilities, and 3 students who had high abilities. The instrument used in this study was in the form of test questions with a description of 6 questions which were arranged based on the cognitive domain of Bloom's taxonomy from the level of questions C3 to C6. The data analysis technique carried out consisted of checking student answers by calculating the percentage of each indicator, determining the type of error in answering the question, and knowing the type of student difficulty. The results showed that students still had difficulties in solving SPLDV problems. The success rate of students in solving SPLDV questions is still relatively low, this can be seen from the number of students who have difficulty solving SPLDV problems, especially on indicators about the ability to apply or use procedures to model and detail the value of the variables asked in a PLDV. The level of difficulty in these indicators is quite high. So that efforts are needed to improve students' ability to understand SPLDV material in online learning.

Abstract

The purpose of this study was to analyze student errors in solving a number of questions on line and angle material using Watson's criteria. The study method used is descriptive qualitative. Class VIII students at one of the MTs in Ciwidey are the research subjects in this study. Furthermore, 3 students were taken as samples with different error levels. The data analysis technique was carried out through 3 stages, namely examining student answers by referring to 8 errors according to Watson, presenting the results of the study in the form of tables and narratives, and conclusions based on research results. From the results of the study, a minor mistake made by students was not including the final conclusion (missing conclusions). Meanwhile, students with errors are making mistakes in the use of problem solving procedures, and do not include final conclusions. And students with high errors make mistakes by including inappropriate data, not using appropriate procedures, missing data and not including conclusions. The errors in indirect manipulation, response level conflicts, hierarchical ability problems and other than the seven errors were not found in the results of this study.
