Abstract

This study describe the analysis of the difficulty of students in completing problem arithmetic operations on mixed numbers class VI MI Darussalam Malang. This type of research is a descriptive study with a qualitative approach. The subjects of this study are students of class VI MI Darussalam Malang with high, medium, and low grades. The results showed that: (1) students in the high and medium grades did not have difficulty in changing mixed fractions to ordinary fractions, however students in the low grade category have difficulty in converting mixed fractions to ordinary fractions; (2) students in the high grade category have no difficulty equating the denominator, however students in the medium and low grade categories have difficulty in equating the denominator of fractions; (3) students with all three categories of high, medium, and low grades have difficulty in calculating fraction operations with three mixed numbers; and (4) students in the high, medium, and low grade categories have difficulty completing the mixed fraction counting operation.

Abstract

The study aims to describe the understanding of group concepts in prospective mathematics teacher with high mathematical abilities. This research is a descriptive qualitative research, with a research subject is a prospective mathematics teacher who have taken group theory courses. The subjects were selected according to the criteria of having high mathematical abilities based on mathematical ability tests, having good communication skills and being able to explain. Data collection was carried out through providing group concept understanding tests followed by interviews. Written tests and interviews were conducted twice for the purposes of triangulating data through time triangulation. Regarding to the discussion section, it can be summarized that subjects with high mathematical abilities can define and show a group fulfilling the traits in detail.

Abstract

The purpose of this study is to describe the application of Reciprocal Teaching with role cards to improve student mathematical reasoning abilities on trigonometry material. Mathematical reasoning is thinking about mathematical problems logically to solve a problem and give reasons for a solution. One of the lessons learned to overcome the low mathematical reasoning ability is the learning of Reciprocal Teaching models using role cards. The steps of Reciprocal Teaching activities include question generating, clarifying, predicting, and summarizing. Before the Reciprocal Teaching steps are carried out, students are given a role card to determine the students who become model teachers. This research is a classroom action research. Based on the research that has been done, it is known that the application of the Reciprocal Teaching model increases the mathematical reasoning ability of students in XI grade IPA 2 of SMA Negeri 8 Malang on the Trigonometry with an increase in class average from initial 73 to 60 in cycle I and to 73 in cycle II. In addition, the average percentage increase in students' mathematical reasoning also increased from 60% to 73%.

Abstract

Most students consider mathematics as a difficult and confusing subject of the many subjects, solid geometry is one of the mathematical subjects considered by students to be the most difficult to understand. Therefore a study was conducted on the difficulties of students in completing the material in solid geometry. The purpose of this study is to describe the difficulty of students in solving mathematical problems in the material surface area and volume of the solid geometry with flat side, especially rectangular solid. This research is a descriptive qualitative research. Based on research that has been done, it is known that students have difficulty understanding concepts and definitions, difficulty applying formulas, and difficulty in calculations.

Abstract

Mathematics subjects, often unknowingly, clash the teacher in instilling character education. Not infrequently, in the process of learning mathematics, the teacher gives a bad character investment. Call it in the subtraction of natural numbers. Often teachers use the word 'borrow'. In fact, he never returned the loan. Then the purpose of the research conducted with this classroom action research method is to improve the learning process so that it no longer instills bad character. The researcher uses lego media as a model of the enumerator in instilling the concept of subtracting natural numbers. The results obtained that by using lego media, students can reduce natural numbers without making mistakes in concepts and learning outcomes obtained in classical completeness is 84.6%. Through this learning, even the cultivation of bad characters can be eliminated.

Abstract

Lack of student interest in learning mathematics is a scourge that needs immediate action. In this study, researchers used the media geoboard and rubber bands as a tool to increase interest in learning. The study was conducted with Classroom Action Research which was successfully completed in two cycles. The results of this study are increased student interest in mathematics before taking action only 12 students, after cycles I and II, made 20 students interested in a total of 22 students. Increasing learning outcomes and concept understanding was very good. At the end of the action in the second cycle it was found that all students had understood the concept of calculating area and circumference of rectangular and triangular shapes.

Abstract

This study aims to show differences in the learning outcomes of applying mind mapping learning with lectures. This study took a population in Class VIII SMP N Open 1 Gumukmas. The sample in this study was taken randomly, namely class VIII TKA Al Aufa as many as 16 students in the class with mind mapping model with LKS and class VIII TKB Baiturrohman 14 students in the class with conventional method. Data collection used test method. Data analysis technique used descriptive statistical analysis. From the results of the research and data analysis, it can be concluded that there are differences in the learning outcomes of the class with mind mapping model with LKS compared to the class with conventional method. This is evidenced by the average value of the class with mind mapping model with LKS getting 80.25 and the class with conventional method of 68.85.
