Abstract

This research is motivated by the low understanding of students' mathematical concepts due to the lack of active participation of students during the learning process. The purpose of this classroom action research is to examine the increase in the ability of students to understand concepts in mathematics learning about Relationships and Functions using the Scientific approach. This research was conducted on 20 students of class VIII SMP Advent Cimindi. This classroom action research was designed in 2 cycles consisting of 4 meetings. The procedure in each cycle includes the stages: planning the action, implementing the action, observing and reflecting. The effectiveness of the action in each cycle is measured from the results of observations of students and teachers during learning and from student learning evaluations. The results showed that the application of a scientific approach could improve students' ability to understand mathematical concepts. This is indicated by an increase in student learning completeness from the first cycle to the second cycle. In the first cycle, the level of student learning completeness reached 55% and in the second cycle increased to 90%. So it can be concluded that learning with a scientific approach can improve students' ability to understand mathematical concepts.

Abstract

Analyze students' mistakes in solving story problems in terms of the aspects of problem representation and solution execution is the aim of this study. Students' mistakes in story problems refer to Newman's theory, including errors: comprehension, transformation, process skills, and encoding. Qualitative descriptive used in this study, with the research subjects were 17 students of class VII at SMPN 3 Tambun Selatan, Bekasi Regency, West Java Province. The test and non-test instruments were used in this study, the test instrument was in the form of story questions related to algebraic form material, while the non-test instrument was an unstructured interview. Research subjects were asked to work on story problems and then analyzed the types of errors. Furthermore, from each type of error, one subject was selected to be interviewed as part of a more in-depth analysis. The results showed that comprehension errors, transformation errors, process skill errors, and encoding errors were caused by errors in the problem representation and solution execution phases. Both phases require students' ability in understanding concepts and fluency in procedures.

Abstract

The purpose of this study was to determine the relationship between the teaching methods used by the teacher and the students' interest in mathematics. This research is a quantitative study with data collection in the form of interviews, questionnaires and documentation of the transcripts of mathematics grades in one of the primary schools. There is a positive relationship between how teachers deliver Mathematics material to students' interest in learning Mathematics. This is used as a topic of discussion because in the learning process, students' interest in the subject is needed. The teaching and learning process which is supported by high interest and enthusiasm from students can make learning much more effective. This is also supported by the opinion of experts on how effective learning can be done, one of which is the relationship between appropriate and fun teaching methods with high student interest. In addition, the author raises the subject of Mathematics because this subject is still a frightening specter for students, especially the response that Mathematics teachers are usually scary and boring teachers. Therefore a study was made that shows how effective the relationship is between the Mathematics Teacher's teaching methods and students' interest in learning about this subject.

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.
