Abstract

This study analyzes students' errors in doing exercises on the material of Straight-Line Equations (PGL) based on the Newman procedure. This research was conducted at one of the schools in Cianjur area, with the research subject of 12 students. The method used in this analysis is the qualitative descriptive method because it will describe the form of student errors. The data collection technique uses 5 test items. The questions were made according to the predetermined indicators of achievement of basic competencies. Furthermore, based on students' answers, the researcher analyzed the extent to the students' errors in solving PGL questions. The results showed that: (1) 50% had errors in reading problems, namely students were less careful; (2) 16.7% experienced errors in understanding the problem, namely not being able to understand (3) 66.7% experienced problem transformation errors, namely difficulties in making graphs from the instructions presented, and students did not correctly convert the information obtained into PGL graphs; (4) 50% experienced errors in process skills, namely students were not able to solve the problems and be careless in the calculation process; (5) 83.3% experienced writing errors/answer notation, namely incorrectly in writing negative signs, symbols, equals signs, not writing variables and conclusions.

Abstract

This research is a classroom action research (CAR) with the main objective of improving students' Mathematical Comprehension Ability (KPM) in algebraic form with the help of the application of a scientific approach. This research is motivated by the lack of student KPM in learning mathematics. This CAR is carried out with research stages including (1) Planning (Planning), (2) Action (Acting), (3) Observing (Observing) and (4) Reflecting (Reflecting). This study has a subject, namely 16 students in class VII C SMP Bhakti Mulya Batujajar with data collection techniques through pretest and posttest in the form of 6 questions, teacher observation sheets and student observation sheets. The implementation of this research is for 2 cycles consisting of 4 meetings. Data analysis was carried out quantitatively and qualitatively. So the result of this research is that the student's KPM in the first and second cycles increased by 18.75% where in the first cycle students' learning completeness was 68.75% in the second cycle to 87.5%. So it can be concluded that, KPM in learning mathematics can be improved with the help of the application of a scientific approach.

Abstract

The importance of mathematical problem-solving abilities for students is that they enable students to overcome various difficulties encountered in order to achieve a goal that is expected in terms of mathematics and everyday life. The research aimed at exploring the causes of difficulties in students' mathematical problem-solving abilities when solving story questions on quadratic functions. Data collection in the research carried out was carried out by giving four items about mathematical problem solving abilities in the quadratic function material. The subject of this research was conducted on 20 grade IX junior high school students in the city of Cimahi. The data analysis technique in this study was descriptive qualitative with the aim of providing a description of students' mathematical problem solving abilities when solving problems on quadratic function material. Based on the research conducted, it was found that students who were able to understand problems as big as they were in medium criteria, students who were able to plan a settlement were in medium criteria, students who were able to make solutions were in medium criteria, and students who were able to check back were in low criteria.
