Abstract


Solving mathematics problem is a mental activity that someone does by using knowledge, skills, and understanding to get the final result as a response. In solving mathematics problem, many students still make mistakes. An error in solving mathematics problem occurs when students answer the question incorrectly. Newman’s Error Analysis is used in this research including reading error, comprehension error, transformation error, process skill error, and encoding error. The causes of students’ error from their intellectual ability in understanding the three dimension topic. The research purpose is to describe (1) the location of error made by high school students in solving mathematics problems related to the three dimension topic and (2) the causes of error made by high school students in solving mathematics problems related to the three dimension topic. The researcher used descriptive qualitative research design. The data were collected at SMA Muhammadiyah 1 Taman Sidoarjo. Four subjects of this research were chosen from XII IPS 2. In this research, students are given mathematics problems for knowing the students’ error in their problem solving. Mathematics problem related to three dimension is used in this paper based test. The researcher used test and interview to collect the data. Data reduction, data display, and conclusion will be used to analyze the data. The result of the research shows that the students made error in solving mathematics problems related to three dimension topic including reading, comprehension, transformation, process skill, and encoding errors. These errors happened because they do not understand keywords in the problem, do not understand concept of distance in three dimension, do not understand concept of angle in three dimension, do not master prerequisite topic including pythagoras theorem and comparison of areas of triangles, cannot write systematic procedure to solve the problem, and careless in encoding.


Keywords: Reading error, comprehension error, transformation error, process skill error, encoding error.
