Abstract

Self-efficacy is a person's feelings, ways of thinking, self-motivation, and desire to have something, while a positive attitude means in the learning process students have a tendency to accept or reject a concept or idea, if not in accordance with his mind. Students can think and be positive if if a learning can provide real benefits for life. While the academic achievement is the result of behavioral changes that include the cognitive domain, affective domain and psychomotor domain which is a measure of student success after being given treatment or learning. This research was conducted at SMK Negeri 1 Sipirok. This study uses descriptive research method with correlational approach with the aim to know whether there is a significant relationship between self-efficacy and positive attitude toward student academic achievement. Based on the research that has been done, the research results found that there is a significant relationship between self-efficacy and positive attitude of students to the academic achievement in SMK Negeri 1 Sipirok Tapanuli Selatan but the relationship is not showing increase or decrease so it can be said academic achievement is not important enough in pushing self-efficacy and positive attitude of students.

Abstract

The background of this paper is to attract society interest to know the beauty of mathematics that is represented by the diversity of mathematics geometry. Truncated Platonic Solid is one of those geometry which is expected to represent the beauty of mathematics. Truncated Platonic solid is a cut off Platonic Solid (not perfect). Platonic Solid is a geometry that was built by congruent polygon, all of the ribs have an equal lenght, also that same surface angle. Truncated Platonic Solid consist of cut off Tetrahedron, cut off Hexahedron, cutt of Dodecahedron, cut off Octahedron, and cutt off Icosahedron. Truncared  Icosidodecahedron is a cut off Icosidodecahedron

Abstract

The purpose of this study is to determine the level of student learning success by applying the method of mind mapping on the subject of the circle and to find out how the implementation of student learning activities by applying the method of mind mapping on the subject of the circle. The subjects of this study are students of SD Negeri 020580 Binjai which consists of 38 students. The tool used to collect data is a test in the form of a description that consists of 10 questions. From the results of data analysis obtained 16 students the success rate is very high, 9 students success rate high, 12 students the success rate is, 1 student success rate is low and no students who not very low success. Based on the data achievement level of student learning outcomes there are 1 students with low success rate and 37 students with high success rate. In terms of learning completeness obtained by the number of students who complete learning (absorbance ≥ 65%) are as many as 37 students (97.37%) and the number of students who are not complete learning (absorption 65%) is as much as 1 student (2.63% ). Based on criteria mastery level and mastery of learning then it can be concluded the level of students of SD Negeri 020580 Binjai is very high. From the results of classroom observation obtained the implementation of good learning activities with active students at every stage of learning activities.

Abstract

This article discussed about theory applaying learning according Van Hiele is learning that focus on Geometry. This theory is found that to study Geometry the student have a development to think step by step certain. The steps student cognitive level consist of 1) Visualisation level is introducing level, 2) Analisys level is description level, 3) Abstraction level (deduction informal) is arraged level or relational level, 4) Deduction formal level, and 5) Rigor level is systhematys level.  This implementation in the class Van Hiele determine some of learing faces 1) Information is about question answer  for introducing the student, 2) Direction method is about the students to know the topic that have been learned by tools with accorate that have prepared the teacher make some observation, 3) Explication is explain a view appear about structure that have observation, 4) Free orientation is how the students faced task more than a way and task  open ended and fase and 5) Integration is the students observe review and resume that have learn. Study applying theory Van Hiele more than applying on student activity, because student activity is role important on the procees of learning used study applying theory.

Abstract

This research aims to determine the effect of using comics media mathematics with the help of powerpoint on motivation and results of students’ mathematics learning on the subject of the matrix inverse order 2x2. This research was conducted in SMK Istiqlal Delitua. The population in this research are 486 students of class X. The sampling in this research using purposive sampling technique are 35 students of class X.AP-1. Based on the results of the test data requirements known that motivation data as well as results of the students’ mathematic learning are distributed normally. Motivation data an average score is 99,2 while the results of students’ mathematics learning data an average score is 19,6. Based on data analysis known that: (1) comics media mathematics are positive and significant impact on motivation to mathematic learn, where t test was obtained thitung = 3,1914 ˃ ttabel = 1,692. The index determination I = 12,5%, it means that comics media mathematics accounted 12,5% with motivation onof mathematic learning; (2) comics media mathematics are positive and significant with the results of students’ mathematics learning. Based on t test was obtained thitung = 6,19 ˃ ttabel = 1,692. The index determination I = 53,77%, it means that comics media mathematics accounted for 53,77% of the increase in the results of students’ mathematics learning.
