Abstract

In learning process must be found the student’s learning difficulties. The difficulties blocked students in learning process caused by several internal factors(talent, motive, intelligence, motivation) and external factors (family, teachers, peers). The student difficulty in learning general is caused by the lack of understanding of mathematical concepts. Skemp states that there are two types of mathematical concepts understanding, namely instrumental understanding and relational understanding. The purpose of research in this article is to describe the students' difficulties to solve the problem in a quadrilateral topic based on Skemp's Understanding theory. Skemp’s Understanding theory indicators include : students ability to classify objects based on requirements that can build this concept, students ability to apply this concept with algorithm , students ability to giving examples of a concept, students ability to present the concept in mathematics representation, students ability to relating various mathematical concepts, and the ability to develop the necessary terms and conditions is quite a concept. This research was designed in qualitative research. The data was collected by test and interview. The results show that the most difficult is about the students ability to relating various mathematical concepts.

Abstract

The relevance of this research is the growth of character values for students in Indonesia. Mathematics is a subject that builds character value for students. This can be seen from how students view mathematics from their perspective. Students' perspective can be seen as a student's assessment of the mathematics such as from the attitudes, interests, self-concepts, values, and morals shown in the learning process of mathematics with the students' willingness to act positively or negatively. In mathematics learning, this is called the affective aspect (AA). One of the factors influencing students’ AA is self-efficacy (SE). SE is a belief that is someone has to complete a given task or problem. There are three categories of SE that owned by students, that is high, medium, and low. The purpose of this study is to determine which ones provide better mathematics AA than students. The research subjects are 294 students in Karanganyar Regency. Data is obtained by questionnaire. Based on the results of data analysis, the conclusion is students with high SE have better mathematics AA than students with moderate and low SE, while students with moderate SE have better mathematics AA than students with low SE.

Abstract

Mathematics is one of the lessons in school. Starting from elementary school, junior high school, senior high school, even college. Mathematics is abstract and identic with numbers, so the author guessed that maybe this is the reason why students consider that mathematics is a difficult lesson. In fact, the learners deliver the material step by step. First, the teacher introduced something concrete to the students (related to the surrounding environment). After that, teacher introduced something more abstract to the students. Sometimes, the transition from concrete to abstract become the problem in the learning process. One of the materials that convert concrete to abstract is systems of linear equations in 8th grade because in this stage students are introduced to more coefficients and variables. This article will discuss how to use media in the form of BBC (Box, Board, and Comics) on systems of linear equations. This research is about Research and Development (R &D). The procedures of comics followed the ADDIE model which included analysis, design, development, implementation, and evaluation. This research aims to create a valid media based on the validation by the and students’ responses which can be proven that BBC (Box, Board, and Comics) media are interesting and worthy to use in the classroom.
