Abstract

This research was conducted with the aim of analyzing the difficulties experienced by students in working on BRSD material problems. This is taken from the cognitive indicators on the bloom taxonomy which are indicators of its difficulty. This research uses a qualitative descriptive method. The data collection technique is by giving questions to students. Furthermore, students' answers are analyzed to determine the extent of the difficulties that occur to students based on the determined indicators. This research was conducted at one of the state junior high schools in Cimahi for the 2020-2021 academic year. The subjects were 20 grade IX students. The instrument inside is a test item with predetermined indicators. The results of the analysis obtained are that there are still students who have difficulty solving indicators of problems that involve cubes. The above is evidenced by the results of the test questions to students where 70% of students experience difficulties with the question indicators as well as the percentage of student answers that are less than the predetermined KKM. The factors that make this indicator experience difficulties are (1) the students' lack of thoroughness in reading, understanding and answering questions; (2) Lack of students' spatial ability to imagine BRSD; (3) Students are accustomed to solving routine problems found in examples.

Abstract

This study aims to find out the difficulties of junior high school students in working on descriptive questions on social arithmetic material and to analyze the factors. The subjects of this study were 26 students of class VIII SMP Buana Panca Bakti Cianjur totaling 26 people in the 2019-2020 school year. Data collection in this study was conducted by means of tests, interviews and documentation. Before the interview, a math test was conducted with 5 questions of social arithmetic material. After the tests and interviews are carried out, the results of the tests and interviews are analyzed and taken from the difficulties the students experience when working on social arithmetic questions. The data analysis techniques used in this study were: (1) data reduction, by selecting the main things and focusing the important things, (2) data presentation, presenting the data on student work, (3) drawing conclusions. The results showed that the students' difficulties when solving social arithmetic problems were difficulties in understanding the problems because social arithmetic problems were in the form of story problems, difficulties in mathematical models and difficulties in the process or steps of completion. The factors that cause students' difficulties because students are lazy to read the questions, it is difficult to digest the words and the meaning of the questions, students are less interested in learning mathematics, and students do not understand the arithmetic operation well.

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.
