Abstract

This study was intended to identify learning obstacles faced by students on the distance between two points and the distance between point-to-line materials. The data in this study was obtained through a test, interview, and documentation of students who have learned the materials. The research method used was the qualitative method with a case study approach. This study involved 33 students of class XII and a teacher as a participant. Learning obstacles found in this study were ontogenical, didactical, and epistemological obstacles. The ontogenical obstacles were the students' lack of basic geometry ability and counting operations of the square root which caused the students to make mistakes in applying the Pythagoras formula, determining the position of perpendicular lines, as well as completing arithmetic operations of the square root. The didactical obstacle was the fact that students were only emphasized on using a quick formula to solve three-dimensional problems. This fact resulted in the uncompleted concept received by students. Consequently, the students forget the proper procedure for solving the problems easily, and they tend to make mistakes in applying the quick formula. The epistemological obstacle was the lack of students' comprehension of a concept to determine the distance between a point to a line if the triangle which is formed is not a right triangle. This lack of comprehension caused the students can’t solve a mathematics problem. The implication of this study is learning materials used by students should be arranged based on students' needs which consider the analysis of learning obstacles so that the learning objectives can be achieved

Abstract

The importance of students' mastery of statistics is supported by the inclusion of this material in the mathematics curriculum since primary and secondary education. The role of statistics itself has penetrated into various professions and fields of science. Regarding statistical mastery students need to have statistical literacy skills in the form of basic skills in reading graphs, graph titles or themes, giving meaning to units of graphs, finding certain values or units, determining maximum and minimum values or the difference between the two. This study aims to describe students' errors in solving statistical literacy test similar to minimum competency assessment or asesmen kompetensi minimum (in Indonesian) based on the Kastolan stages. The type of this study is qualitative research with a case study design. The subjects of this research were 5 students of grade 11, a senior high school in Banjarbaru, South Borneo, selected using purposive sampling technique. Data were collected using tests and interviews. During the study, it was found that errors made by students include conceptual errors, procedural errors, and technical errors. Students' errors in solving statistical literacy test can have an impact on their daily life when they are dealing with data. Moreover, errors made by students when solving problems can be an early sign that there are learning obstacles experienced by students.
