Mathematical learning based on ethnomathematics applying local culture can change the perception of the society about the applications of mathematics in everyday life. The purpose of this study was to describe the increase in high school students' cognitive level through the implementation of realistic mathematics learning model based on ethnomathematics in Bengkulu. This study was an assessment phase of development research employing a 2 × 2 factorial experimental design with students' initial performance being controlled. There were three main findings of this study. First, mathematical understanding of students taught using realistic mathematics learning was higher than those who taught using the conventional method (the learning materials in both groups was non-ethnomathematics oriented). Second, mathematical understanding of students learned the ethnomathematics oriented materials was higher than those learned non-ethnomathematics oriented materials (realistic mathematics learning applied in both groups). Third, mathematical understanding of students who learned the ethnomathematics oriented materials was lower compared to the students learned the non-ethnomathematics materials (the conventional learning method applied in both groups).

The purpose of this study was to describe students’ thinking processes in understanding the concept of graphs during ethnomathematics learning. This research was part of development research. This was the prototype stage. The subjects of this study were 26 students in the University of Bengkulu. The instrument of this study was the researchers themselves plus interview guides, anecdotes and observation sheets. Data collection was done during ethnomathematics learning. Data were analyzed qualitatively with the constant comparative technique. The results of this study were students begin learning with a culture of communication using mobile phones. Students think about the definition of graph by corresponding to a cellphone with a vertex. The edge of a graph was corresponded to the existence of a relationship between mobile phones. Students c...

The highest quality of the students in proving the theorem was extended abstract. One of the theorems that was difficult to determine was Lobachevsky’s parallel lines. The purpose of this study was to describe the characteristics of extended abstract level students in proving the Lobachevsky parallel lines theorem. This was part of research development. This stage was the student analysis phase. The subjects of this study were 21 Mathematics Education Pre-service teachers who were taking Geometry courses. The instrument of this study was the researchers themselves with the help of task sheets and interview guides. Data was collected through task-based interviews. Qualitative data analysis techniques with fixed comparison techniques. The results of this study were that students were able to understand the axiom “through a point outside the line g, there were at least two lines parallel to g”. This axiom was used to prove the Nonmetrical Theorem. Also, students were able to prove that...
