Abstract

Social arithmetic is material that is directly related to the application of mathematics in everyday life. But the facts show that students find it difficult to learn the material. This study was conducted with the aim of describing the identification of the difficulties of junior high school students in working on social arithmetic problems. In this research using a qualitative descriptive method. The data taken using the technique of giving test questions in the form of descriptions to students with indicators that have been set as instruments consisting of 6 questions, then further analyzing student answers. Data analysis was carried out, namely data reduction, data presentation and conclusion drawing. The analysis aims to determine the students' difficulties in social arithmetic lessons. The object of research is 25 students in one of the Cililin State Junior High Schools. The instrument is a test question regarding social arithmetic with different levels of questions. The results showed that there were 3 types of difficulties, namely: (1) difficulties in language aspects, such as students having difficulty understanding and translating questions and even difficulty in retelling in their own language; (2) Difficulty in the prerequisite aspects, the sequence from the language aspect makes students unable to copy back what is known and what is asked, students also understand a little about the concept of determining formulas; (3) difficulties in applied aspects, for example, students have difficulty carrying out counting methods, making it difficult for students to determine the common thread from these answers. This difficulty is caused because students do not fully understand the social arithmetic material.

Abstract

This study aims to analyze the critical thinking skills of junior high school students on Pythagoras material. Subjects in this study are students of class VIII-F in SMP Negeri 1 Ngamprah with the number of students 37 people. The method used in this research is qualitative descriptive. This type is chosen because it aims to describe the skills of students in solving problems of mathematical critical thinking independently. The research phase is divided into three, namely planning, implementation, and reporting. The technique of collecting data in the form of test. Data analysis techniques based on indicators of mathematical critical thinking skills that has been determined by researchers include: (1) identifying the concepts used in problem solving, (2) formulating an action (strategy, tactics, or approach) in solving problems, (3) providing arguments or reasons for answering and solving problems, and (4) evaluating evidence or decisions taken in solving the problem. The results obtained quantitatively show that the level of mathematical critical thinking skills of students in SMP Negeri 1 Ngamprah in solving the problems on Pythagoras material still falls into the low category. The evidence from the percentage of each indicator with the highest rate of only 61%. Some factors influence the level of students critical thinking skills, including the preparation of incomplete and appropriate strategies, provide arguments without showing the truth, and the students' accuracy in working on the questions.

Abstract

The aims of this research is to describe students' higher order thinking skills in solving social arithmetic problems. The method in this study is a qualitative descriptive method. The data collection technique is by giving higher order thinking skill test questions to students. Then further analyze students' answers and assess students' higher order thinking skills in social arithmetic material. The object of this research is 20 students in a private junior high school in West Bandung Regency. The instrument used is a test about social arithmetic material with the type of higher order thinking skill. The results of the study prove that students still experience problems in solving problems on Higher Order Thinking Skill questions at 3 levels of Bloom's taxonomy, namely: analyzing (C4); evaluate (C5); and create (C6). This is evidenced by the results of the students' higher order thinking skills which show that no one gets the very good category, most of the students only get the sufficient category. The factors that make the problem experience problems are (1) Not being able to analyze; (2) Unable to refute, evaluate or support an idea and cannot find reasons to support the answers obtained; (3) Unable to provide solutions to problems and integrate information into correct steps.
